Optionally, fig. 5 is a schematic structural diagram of another display panel according to an embodiment of the present invention, as shown in fig. 5, two opposite first gate driving circuits 40 are provided, one first gate driving circuit 40 is disposed at a first end of a row of scanning signal lines 10, and the other first gate driving circuit 40 is disposed at a second end of the row of scanning signal lines 10; each adjacent N rows of scanning signal lines in the multiple rows of scanning signal lines 10 form a line group; the first gate driving circuit 40 at the first terminal is used for driving the odd line groups, and the first gate driving circuit 40 at the second terminal is used for driving the even line groups.

By analogy, each adjacent 6 rows of scanning signal lines in the multiple rows of scanning signal lines 10 may form a line group, the odd line group is driven by the first gate driving circuit 40 located at one end of the scanning signal line 10, and the even line group is driven by the first gate driving circuit 40 located at the other end of the scanning signal line 10, so that the line layout is more reasonable, mutual interference is avoided, and a narrow frame of the display panel is facilitated.
For convenience of description, in the embodiments of the present invention, the display panel shown in fig. 5 is taken as an example to exemplarily describe the technical solution of the embodiments of the present invention without special description.
Optionally, fig. 6 is a schematic structural diagram of another display panel according to an embodiment of the present invention, and as shown in fig. 6, the first gate driving circuit 40 further includes a 1 st to an nth timing control line CKH; the multiplexing unit 42 includes the 1 st to nth control terminals C; an ith control terminal Ci in the multiplexing unit 42 is electrically connected to an ith timing control line CKHi for transmitting a scanning signal to an ith scanning signal line in the N rows of scanning signal lines when turned on, wherein i is greater than or equal to 1 and less than or equal to N.
Specifically, on the basis of the structure shown in fig. 5, fig. 6 exemplarily shows a structural diagram of a display panel with N being 6, each of the multiple selecting units 42 includes the 1 st to 6 th control terminals C (C1, C2 … … C6), wherein the 1 st control terminal C1 is electrically connected to the 1 st timing control line CKH1, the 2 nd control terminal C2 is electrically connected to the 2 nd timing control line CKH2, and so on. Thus, for example, when the timing control signal Ckh2 outputted from the 2 nd timing control line CKH2 controls the corresponding scan signal line in the multiplexer unit 42 to be turned on through the 2 nd control terminal C2, the scan signal Ckv1 provided by the first scan source line CKV1 may be transmitted to the 2 nd scan signal line in the N rows of scan signal lines, so that the plurality of sub-pixels 30 electrically connected to the row of scan signal lines are turned on, and the sub-pixels 30 are charged by the data signal S provided by each data signal line 30. Therefore, the structure of the first gate driving circuit can be effectively simplified under the condition that the display quality of the display panel is not influenced, so that the size of the frame of the display panel is reduced, and the narrow frame of the display panel is realized.
It should be noted that the timing control line CKH controls the conduction of the 1 st to nth control terminals C in the multiplexing unit 42 in a time-sharing manner, so as to avoid that the scanning signals are all transmitted to the N rows of scanning signal lines at the same time to affect the normal display of the display frame.
Optionally, fig. 7 is a schematic structural diagram of another display panel provided in the embodiment of the present invention, and as shown in fig. 7, the multiplexing unit 42 includes 1 st to nth switching devices T; the control end of the ith switching device Ti is the ith control end Ci of the multi-path selection unit 42, the input end is electrically connected to the first scanning source line CKV, and the output end is electrically connected to the ith scanning signal line, and is used for being turned on or off under the control of the ith timing control line CKHi.
Specifically, fig. 7 exemplarily shows a structural diagram of a display panel in which N is 6, a control terminal of a 1 st switching device T1 in the multi-path selection unit 42 is C1, and C1 is electrically connected to a 1 st timing control line CKH1, an input terminal of the 1 st switching device T1 is electrically connected to the first scan source line CKV, and an output terminal of the 1 st switching device T1 is electrically connected to the 1 st scan signal line; similarly, the control terminal of the 2 nd switching device T2 is C2, and C2 is electrically connected to the 2 nd timing control line CKH2, the input terminal of the 2 nd switching device T2 is electrically connected to the first scan source line CKV, the output terminal of the 2 nd switching device T2 is electrically connected to the 2 nd scan signal line, and so on. As such, for example, when the timing control signal Ckh2 outputted from the 2 nd timing control line CKH2 controls the 2 nd switching device T2 to be turned on through the 2 nd control terminal C2, the scan signal Ckv1 provided by the first scan source line CKV1 may transmit the 2 nd scan signal line to enable the plurality of sub-pixels 30 electrically connected to the 2 nd scan signal line to be turned on, so that the data signal S provided by each data signal line 30 starts to charge the sub-pixels 30. Therefore, the structure of the first gate driving circuit 40 can be effectively simplified without affecting the display quality of the display panel, so that the size of the frame of the display panel is reduced, and the narrow frame of the display panel is realized.
Optionally, with continued reference to fig. 7, the switching devices T of the multiplexing unit 42 are both N-type transistors or both P-type transistors.
Specifically, when the switching device T of the multi-path selection unit 42 is an N-type transistor, the timing control signal Ckh for controlling the switching device T to be turned on is all at a high level, and the timing control signal Ckh for controlling the switching device T to be turned off is all at a low level; when the switching device T of the multiplexing unit 42 is a P-type transistor, the timing control signal Ckh for controlling the switching device T to be turned on is at a low level, and the timing control signal Ckh for controlling the switching device T to be turned off is at a high level. In this embodiment, the switching devices T of the multi-path selection unit 42 are all N-type transistors or all P-type transistors, so that the time-limited control lines of the first gate driving circuit can be simplified, the size of the frame of the display panel can be reduced, and the narrow frame of the display panel can be realized.
Optionally, fig. 8 is a timing diagram of a first gate driving circuit according to an embodiment of the present invention, and with reference to fig. 6 and 8, an operation process of any timing control line CKH in the first gate driving circuit 40 includes a first turn-on phase t1(ii) a At the first start-up period t of the ith timing control line CKHi1The multiplexer unit 42 transmits the scanning signalTo the ith scanning signal line.
Specifically, fig. 8 exemplarily shows a timing diagram of the first gate driving circuit with N being 6, and the display panel 100 further includes a first start signal line STV1 and a second start signal line STV2 (both not shown in the figure), and at the beginning of each scan cycle, the first start signal line STV1 outputs the driving signal STV1 and transmits the driving signal STV1 to one first gate driving circuit 40, and the second start signal line STV2 outputs the driving signal STV2 and transmits the driving signal STV 3538 to another first gate driving circuit 40, so that the first shift register unit 41 in the first gate driving circuit 40 starts to operate. When the first scan source line CKV is active (e.g. high), the first scan source line CKV provides the scan signal Ckv for the multiplexer unit 42, and the operation process of any timing control line CKH includes a first start-up phase t1At the first turn-on stage t of the ith timing control line CKHi1When the timing control signal CKHi provided by the ith timing control line CKHi is an active signal (e.g., high level), the corresponding scan signal line is controlled to be turned on by the ith control terminal Ci of the multiplexing unit 42, so that the multiplexing unit 42 transmits the scan signal Ckv to the ith scan signal line, and the data signal S output by each data signal line 30 charges each sub-pixel 30 electrically connected to the ith scan signal line, thereby displaying a corresponding display image.
It should be noted that, at the stage when the first scan source line CKV outputs the valid signal, the timing control line CKH controls the scan signal line to be turned on in a time-sharing manner, and the specific scan timing of the embodiment of the present invention is not particularly limited, and may be, for example, line-by-line scanning or line-crossing scanning.
Illustratively, when the first scan source line CKV1 is an active signal (e.g., high level), the first scan source line CKV1 provides the scan signal Ckv1 to the multiplexing unit 42, and during the first on-phase t1 of the 1 st timing control line CKH1, the timing control signal Ckh1 provided by the 1 st timing control line CKH1 is an active signal (high level), and the multiplexing unit 42 transmits the scan signal Ckv1 to the 1 st scan signal line, so that each data signal line 30 outputs the data signal S to charge each sub-pixel 30 electrically connected to the 1 st scan signal line. Then, the 2 nd timing control line CKH2 enters the first onStarting phase t1And the output timing control signal Ckh2 is an active signal (high level), the multiplexing unit 42 transmits the scan signal Ckv1 to the 2 nd scan signal line, so that each data signal line 30 outputs the data signal S to charge each sub-pixel 30 electrically connected to the 2 nd scan signal line. And so on until the multiplexing unit 42 transmits the scan signal Ckv1 to the 6 th scan signal line and causes each data signal line 30 to output the data signal S to charge each sub-pixel 30 electrically connected to the 6 th scan signal line.
Then, based on the same principle, after the first scan source line CKV1 outputs the valid signal, the first scan source line CKV2 outputs the valid signal (for example, high level), and performs scanning according to a set scanning manner, for example, progressive scanning, and transmits the scan signal Ckv2 output by the first scan source line CKV2 to the 7 th to 12 th scan lines, which is not described herein again in detail.
Optionally, fig. 9 is a timing diagram of another first gate driving circuit according to an embodiment of the invention, and as shown in fig. 9, the operation process of at least one timing control line CKH further includes a first turn-on period t1Preceding pre-opening phase t0(ii) a At the first start-up period t of the ith timing control line CKHi1Before the end, the (i + 1) th timing control line CKHi +1 enters the pre-start stage t0(ii) a At the first start-up period t of the ith timing control line CKHi1And pre-start phase t of the (i + 1) th timing control line CKHi +10The multiplexing unit 42 transmits the scanning signals to the ith scanning signal line and the (i + 1) th scanning signal line, respectively.
Specifically, fig. 9 exemplarily shows a timing diagram of the first gate driving circuit with N being 6, when the first scan source line CKV is an active signal (e.g. high level), the first scan source line CKV provides the scan signal Ckv for the multi-path selecting unit 42, and at this time, the operation process of at least one timing control line CKH further includes during the first turn-on period t1Preceding pre-opening phase t0At the first turn-on stage t of the ith timing control line CKHi1Before the end, the (i + 1) th timing control line CKHi +1 enters the pre-start stage t0. In other words, the ith timing controlLine CKHi is in the first turn-on phase t1When an active signal (e.g., high level) is outputted to control the ith control terminal Ci of the multiplexer unit 42 to be turned on, the ith +1 th timing control line CKHi +1 enters the pre-start-up stage t0And outputs an active signal (e.g., a high level) to control the i +1 th control terminal Ci +1 of the multiplexing unit 42 to be turned on, so that the scan signal Ckv provided from the first scan source line CKV is transmitted to the i-th scan signal line and the i + 1-th scan signal line, respectively, through the multiplexing unit 42. In this way, when the scan signal Ckv provided by the first scan source line CKV is transmitted to the scan signal line of the current row, the sub-pixels 30 of the current row are driven to be turned on, so that the data signal line 20 provides the data signal S to charge the sub-pixels 30 on the row; meanwhile, before the scanning is finished, the same scanning signal Ckv is provided to the scanning signal line of the next row, so that the charging time of the sub-pixels 30 of the next row is prolonged, the charge quantity of the storage capacitors in the sub-pixels 30 is increased, the stability of the display picture is ensured, and the display quality is improved.
Illustratively, when the first scan source line CKV1 is active (e.g., high), the first scan source line CKV1 provides the scan signal Ckv1 to the multiplexer unit 42 during the first turn-on period t of the 1 st timing control line CKH11The timing control signal Ckh1 provided by the 1 st timing control line CKH1 is an active signal (high level), and the multiplexing unit 42 transmits the scan signal Ckv1 to the 1 st scan signal line, so that each data signal line 30 outputs the data signal S to charge each sub-pixel 30 electrically connected to the 1 st scan signal line. Before the end of the first row scan, the 2 nd timing control line CKH2 enters the pre-start phase t0And the output timing control signal Ckh2 is an active signal (high level), at this time, the multiplexing unit 42 transmits the scan signal Ckv1 to the 2 nd scan signal line, so that each data signal line 30 outputs the data signal S to charge each sub-pixel 30 electrically connected to the 2 nd scan signal line. It is apparent that the charging time period of each sub-pixel 30 electrically connected to the 2 nd scanning signal line is equal to the total time period of the first turn-on period plus the pre-turn-on period, extending the charging time of the plurality of sub-pixels 30 electrically connected to the 2 nd scanning signal line.
Alternatively, with continued reference to FIG. 9, of the ith timing control lineFirst opening phase t1Is earlier than or equal to the pre-start period t of the (i + 1) th timing control line0The starting time of (c).
Specifically, the first start-up stage t of the ith timing control line1May be earlier than the pre-start period t of the (i + 1) th timing control line1In other words, the first turn-on period t of the ith timing control line1Is in the pre-start stage t of the (i + 1) th timing control line0Before the start time of (c). Referring to FIG. 9, at this time, the pre-start period t of the (i + 1) th timing control line0First start-up period t of ith timing control line1The overlapping of the partial time periods can also meet the requirement of prolonging the charging time of the sub-pixels 30 in the row where the scanning signal line controlled by the (i + 1) th time sequence control line is positioned, thereby improving the stability of the display picture.
In addition, in another embodiment, the first turn-on period t of the ith timing control line1And the pre-start stage t of the (i + 1) th timing control line0The starting time of (2) is the same, as shown in fig. 10. At this time, the pre-start stage t of the (i + 1) th timing control line0First start-up period t of ith timing control line1The overlap is complete, and compared with fig. 9, the charging time of the sub-pixels 30 in the row where the scanning signal line controlled by the (i + 1) th timing control line is located can be further prolonged, thereby improving the stability of the display screen.
Optionally, with continued reference to fig. 9 or 10, one or more of the 2 nd to nth timing control lines CKH2 and CKH include a pre-turn-on stage t0
For example, when N is 6, only one timing control line CKH (e.g., CKH4) of the 2 nd to 6 th timing control lines CKH2 to CKH6 or a plurality of timing control lines CKH (e.g., a plurality of timing control lines CKH2, CKH4 and CKH6) may include a pre-turn-on stage t0The embodiment of the present invention does not specifically limit this, and may be selectively set according to actual conditions. Thus, it includes a pre-opening stage t0The timing control line CKH, especially the charging time of the sub-pixels 30 in the row of the turned-on scanning signal line, can be controlled by the pre-start-up staget0The display screen is prolonged, and the stability of the display screen is improved.
Preferably, the 2 nd to 6 th timing control lines CKH2 to CKH6 may each include a pre-start phase t0Therefore, the picture stability of the whole display panel in one scanning period is ensured, and the display quality of the display panel is improved.
Alternatively, as shown in fig. 6, 9 and 10, a plurality of columns of data signal lines 20 and a plurality of rows of sub-pixels 30, a row of scanning signal lines 10 is electrically connected to a row of sub-pixels 30, and a column of data signal lines 20 is electrically connected to a column of sub-pixels 30; n rows of sub-pixels 30 are driven by N rows of scanning signal lines 10 corresponding to one first scanning source line CKV; the operation of a row of sub-pixels 30 comprises a charging phase t2(ii) a Charging phase t of i-th row of sub-pixels 30 in N rows of sub-pixels 302The ith timing control line CKHi enters the first start-up stage t1The first scan source line CKV provides an effective scan signal to the ith scan signal line 10, and the data signal line 20 provides a corresponding ith row of data signals to the ith row of sub-pixels 30.
It is understood that a plurality of scan signal lines 10 and a plurality of data signal lines 20 intersect to define a plurality of pixels 30, and the plurality of sub-pixels 30 are arranged in a plurality of rows and columns in an array. N rows of scanning signal lines are correspondingly connected to one first scanning source line CKV through one multiplexing unit 42, so that the scanning signal Ckv of the first scanning source line CKV is transmitted to the N rows of scanning signal lines 10 in a time-sharing manner through the multiplexing unit 42 to drive the N rows of sub-pixels 30.
Specifically, as shown with reference to FIG. 9 or FIG. 10,
for example, the charging period t is defined as the active signal (high level) period of the timing control signal Ckh1 provided by the 1 st timing control line CKH12At this time, the 1 st timing control line CKH1 enters the first turn-on stage t1The first scan source line CKV provides an active scan signal (high level) to the 1 st scan signal line 10 to drive the sub-pixels 30 electrically connected to the 1 st scan signal line to be turned on, and the data signal line 20 outputs the corresponding 1 st row data signal S (S1, S2 … … Sm) and transmits the data signals to the sub-pixels 30 in the 1 st row for charging.
Optionally, as shown in fig. 6, 9 and 10, the charging phase t of the ith row of sub-pixels in the N rows of sub-pixels2If the ith timing control line enters the pre-start stage t of the (i + 1) th timing control line0The first scan source line CKV further provides an effective scan signal to the (i + 1) th scan signal line, and the data signal line 20 further provides the (i + 1) th row of data signals to the sub-pixels of the (i + 1) th row.
Specifically, the operation process of at least one timing control line CKH further includes a first start-up period t1Preceding pre-opening phase t0The ith timing control line CKHi is in the first start-up stage t1When an active signal (e.g., high level) is outputted to control the ith control terminal Ci of the multiplexer unit 42 to be turned on, the ith +1 th timing control line CKHi +1 enters the pre-start-up stage t0And outputs an active signal (e.g., a high level) to control the i +1 th control terminal Ci +1 of the multiplexing unit 42 to be turned on, so that the scan signal Ckv provided from the first scan source line CKV is transmitted to the i-th scan signal line and the i + 1-th scan signal line, respectively, through the multiplexing unit 42. At this time, since the data signal output from the data signal line 20 is a data signal corresponding to the i-th row of sub-pixels, the data signal is pre-turned on at the i-th timing control line and the i + 1-th timing control line in the pre-turn-on period t0In the overlapping time period, the ith row data signal output by the data signal line 20 is also provided to the (i + 1) th row sub-pixels, so as to charge the (i + 1) th row sub-pixels. Thus, the i +1 th timing control line includes a pre-start stage t0And in the pre-start-up period t0The first scanning source line CKV also provides an effective scanning signal for the (i + 1) th scanning signal line, so that the data signal line 20 also provides the (i) th row of data signals for the (i + 1) th row of sub-pixels, the charging time of the (i + 1) th row of sub-pixels is prolonged, the charge quantity of the storage capacitor in the sub-pixel 30 is increased, the stability of a display picture is ensured, and the display quality is improved.
It should be noted that the ith row data signal and the (i + 1) th row data signal may be the same or different, and are specifically related to the color of the sub-pixel 30 and the picture to be presented, and the embodiment of the present invention is not limited herein.
Illustratively, referring to fig. 9, the input is at the first scan source line CKV1When the active scan signal is asserted (Ckv 1 is high), the active signal (high) period of the timing control signal Ckh1 provided by the 1 st timing control line CKH1 is the charging period t2At this time, the 1 st timing control line CKH1 enters the first turn-on stage t1The first scan source line CKV1 provides an active scan signal (high level) to drive the sub-pixels 30 electrically connected to the 1 st scan signal line to turn on, and the data signal line 20 outputs the corresponding 1 st row data signal S, and transmits the data signal S to the 1 st row sub-pixels 30 respectively to charge the sub-pixels. When the 1 st time sequence control line enters and the 2 nd time sequence control line pre-start period t0The first scan source line CKV1 also provides an active scan signal (high level) to the 2 nd scan signal line, and the data signal line 20 also provides the 1 st row data signal S to the 2 nd row sub-pixels, and transmits them to the 2 nd row sub-pixels 30 respectively to charge them.
Optionally, fig. 11 is a timing diagram of another first gate driving circuit according to an embodiment of the invention, and as shown in fig. 11, the 2 i-th timing control line CKH2i includes a precharge stage t3And the 2i-1 th timing control line CKH2i-1 does not include the precharge phase t3I is less than or equal to N/2.
Specifically, fig. 11 exemplarily shows a timing diagram of the first gate driving circuit where N is 6, and the even number timing control lines CKH2i include a precharge phase t3Charging phase t3Comprising a pre-opening phase t0The odd number of timing control lines CKH2i-1 do not include the precharge phase t3. In a stage where the first scan source line CKV outputs the active scan signal, a 2i-1 th timing control line CKH2i-1 among the odd number of timing control lines CKH is in a first turn-on stage t1When an active signal (e.g., high level) is outputted to control the 2i-1 control terminal C2i-1 of the multi-way selection unit 42 to be turned on, the even-numbered timing control line CKH2i of the 2i-1 timing control line CKH2i-1 has entered the pre-start stage t0And outputs an active signal (e.g., a high level) to control the 2i control terminal C2i of the multiplexing unit 42 to be turned on, so that the scan signal Ckv provided by the first scan source line CKV is transmitted to the 2i-1 th scan signal line and the 2i scan signal line through the multiplexing unit 42, respectively. Then, the number of data signal line 20 outputsThe signals are transmitted to the sub-pixels in the 2i-1 th row and the sub-pixels in the 2i-1 th row, the sub-pixels in the 2i-1 th row are normally charged to present a corresponding display picture, and meanwhile, the sub-pixels in the 2i-1 th row are pre-charged to prolong the charging time of the sub-pixels in the 2i-1 th row and improve the stability of the display picture and the display quality of the display panel.
It should be noted that, the first turn-on period t of the 2i-1 th timing control line CKH2i-1 and the 2 i-2 th timing control line CKH2i, and the 2i-1 th timing control line CKH2i-1 are adjacent to each other1Is earlier than or the same as the pre-start period t of the 2 i-th timing control line CKH2i-10The start time of the present invention is not particularly limited in this respect. Preferably, referring to FIG. 11, the first turn-on phase t of the 2i-1 th timing control line CKH2i-11And the pre-start period t of the 2 i-th timing control line CKH2i0The starting time of the first row sub-pixels is the same time, so that the sub-pixels in the 2i-1 th row on the 2i scanning line controlled to be conducted by the 2i timing control line CKH2i can be ensured to have sufficient charging time, the stability of a display picture can be ensured, and the display quality is improved.
In this embodiment, the even number of timing control lines CKH2i are set to include a precharge phase t3The odd number of timing control lines CKH2i-1 do not include the precharge phase t3Therefore, the abnormal phenomenon of the display picture caused by the larger difference between the 2 i-th row data signal and the next row data signal can be avoided.
Optionally, with continued reference to fig. 9 and 11, the first turn-on phase t of the 2 i-th timing control line1Is earlier than the pre-start period t of the 2i +2 th timing control line0The starting time of (c).
Specifically, the first start-up period t of the 2 i-th timing control line1Pre-start stage t of 2i +2 time sequence control line0With a certain time interval, Gap, to prevent the first turn-on period t of the 2 i-th timing control line1The 2i +2 th time sequence control line enters the pre-starting stage t0. If the charging time of the two is overlapped, the 2i row data signal output by the data signal line charges the 2i row sub-pixel 30 and also charges the 2i +2 row sub-pixel 30Charging, which will cause the display to be abnormal. Especially, the sub-pixels in the 2i th row are not adjacent to the sub-pixels in the 2i +2 th row, when the difference between the data signal in the 2i th row and the data signal in the 2i +2 th row is large, the display of the display panel is seriously affected, and the display quality is reduced.
Alternatively, as shown in fig. 6 and fig. 11, a plurality of columns of data signal lines 20 and a plurality of rows of sub-pixels 30, a row of scanning signal lines 10 electrically connected to a row of sub-pixels 30, and a column of data signal lines 20 electrically connected to a column of sub-pixels 30; n rows of sub-pixels 30 are driven by N rows of scanning signal lines 10 corresponding to one first scanning source line CKV; the operation of a row of sub-pixels 30 comprises a charging phase t 2; charging phase t of i-th row of sub-pixels in N rows of sub-pixels 302The ith timing control line enters the first start-up stage t1The first scan source line CKV provides an effective scan signal to the ith scan signal line 10, and the data signal line 20 provides a corresponding ith row of data signals to the ith row of sub-pixels.
Optionally, with continued reference to FIG. 11, during the charging phase of the sub-pixels in the 2i-1 th row of the N rows of sub-pixels, if the 2i-1 st timing control line CKH2i-1 enters the pre-start phase t of the 2i timing control line CKH2i1The first scan source line CKV also provides an effective scan signal to the 2 i-th scan signal line, and the data signal line 20 also provides the 2i-1 th row of data signals to the 2 i-th row of sub-pixels.
Specifically, the 2i-1 th timing control line CKH2i-1 is in the first turn-on period t1When the valid signal (e.g., high level) is outputted to control the conduction of the 2i-1 control terminal C2i-1 of the multi-way selection unit 42, the 2 i-th timing control line CKH2i has entered the pre-start-up period t0And outputs an active signal (e.g., a high level) to control the 2i control terminal C2i of the multiplexing unit 42 to be turned on, so that the scan signal Ckv provided by the first scan source line CKV is transmitted to the 2i-1 th scan signal line and the 2i scan signal line through the multiplexing unit 42, respectively. At this time, the data signal outputted from the data signal line 20 is a data signal corresponding to the 2i-1 th scanning signal line, and therefore, the pre-start period t is set in the 2i-1 st timing control line and the 2 i-th timing control line0Coincidence period, which is output from the data signal line 20 and corresponds to the 2i-1 th scanning signal lineThe data signal is also provided to the sub-pixels of the 2i th row, and the sub-pixels of the 2i th row are charged.
Thus, since the 2 i-th timing control line includes the pre-turn-on period t0And in the pre-start-up period t0The first scanning source line CKV also provides an effective scanning signal for the 2 i-th scanning signal line, so that the data signal line 20 also provides a 2i-1 th row of data signals for the 2 i-th row of sub-pixels, the charging time of the 2 i-th row of sub-pixels is prolonged, the charge amount of the storage capacitor in the sub-pixel 30 is increased, the stability of a display picture is ensured, and the display quality is improved.
Optionally, fig. 12 is a schematic structural diagram of another display panel provided in this embodiment, as shown in fig. 12, in the N rows of sub-pixels 30, the 2j-1 th row of sub-pixels and the 2j row of sub-pixels have the same color, and j is greater than or equal to 1 and less than or equal to N/2.
It can be understood that the 3D display panel is generally used for displaying 3D stereoscopic effects, and the stereoscopic vision is generated by separating display frames of the display panel viewed by left and right eyes of a person and observing a difference in angles of an object with both eyes of the person. Therefore, when the sub-pixels in the 3D event panel are arranged, the pixels in two adjacent rows are the same pixels for the left and right eyes, and in actual use, the difference in the display screen of the display panel seen by the left and right eyes is small, that is, the difference in the potential of the sub-pixels in two adjacent rows is small. Therefore, the voltage value difference of the data signals for charging the adjacent sub-pixels is relatively large, so that the stability of a display picture is ensured, and the display quality of the display panel is improved.
Specifically, in the N rows of sub-pixels 30, the 2j-1 th row of sub-pixels and the 2j row of sub-pixels have the same color, so that the odd rows of sub-pixels can be used for presenting the picture seen by the left eye of a person, and the even rows of sub-pixels can be used for presenting the picture seen by the right eye of the person, so that the 3D display panel presents a stereoscopic visual picture.
It should be noted that the arrangement of the subpixels 30 in the N rows is AABBCC, wherein specific colors of the subpixels 30 represented by A, B and C are not particularly limited in the embodiment of the present invention, and can be selectively set according to practical applications. For example ABC, is RGB in sequence.
Optionally, N ═ 6; for the N rows of sub-pixels, the N rows of sub-pixels comprise two adjacent rows of red sub-pixels (R), two adjacent rows of green sub-pixels (G) and two adjacent rows of blue sub-pixels (B).
Specifically, fig. 12 exemplarily shows a structural diagram of a display panel with N being 6, in each 6 rows of sub-pixels 30, the sub-pixels in the 2j-1 th row and the sub-pixels in the 2j th row have the same color, and j is greater than or equal to 1 and less than or equal to N/2. For example, the arrangement order of the sub-pixels 30 in the 6 rows is RRGGBB, which is not particularly limited in this embodiment of the present invention, and other arrangement manners may also be used. Thus, the 1 st, 3 rd and 5 th row sub-pixels may constitute one display pixel corresponding to presentation of a display screen to the left eye of a person; the sub-pixel of the 2 nd row, the sub-pixel of the 4 th row and the sub-pixel of the 6 th row can form another display pixel corresponding to the display picture of the right eye of a person, so that the 3D display panel can display a stereoscopic visual picture.
For example, fig. 13 is a timing diagram of another first gate driving circuit according to an embodiment of the invention, and in a period when the first scan source line CKV1 outputs an active scan signal (i.e. Ckv1 is a high level period), the 1 st timing control line CKH1 enters a first turn-on period t shown in fig. 12 and 131(i.e. charging phase t)2) The first scan source line CKV1 provides an active scan signal (high level) to drive the sub-pixels 30 electrically connected to the 1 st scan signal line to be turned on, and the data signal line 20 outputs the corresponding 1 st row data signal S of 4.6V, and transmits the data signal S to the 1 st row sub-pixels 30 respectively to charge the sub-pixels. When the 1 st time sequence control line enters and the 2 nd time sequence control line pre-start period t0Overlap period of (i.e. precharge phase t)3) The first scan source line CKV1 also provides an active scan signal (high level) to the 2 nd scan signal line, and the 1 st row data signal S (4.6V) output from the data signal line 20 also charges the 2 nd row sub-pixels 30. When the 1 st time sequence control line is in the first start stage t1After the end, the 2 nd time sequence control line enters the first opening stage t1(i.e. charging phase t)2) At this time, the first scan source line CKV1 provides an active scan signal (high level) to drive the sub-pixels 30 of the 2 nd row to be continuously turned onThe data signal line 20 outputs the row 2 data signal S of 3.5V, which is transmitted to the row 2 sub-pixels 30 to charge the same.
Because the difference between the voltage value of the data signal S in row 1 and the voltage value of the data signal S in row 2 is small, the potential of the sub-pixel 30 in row 2 can be quickly restored to the correct potential (3.5V), and compared with the case that the potential of the sub-pixel 30 in row 2 is directly from 0V to 3.5V, the transient time for stabilizing the potential of the sub-pixel is saved, and the storage amount of charges in the sub-pixel is increased, thereby improving the stability of the display picture.
Based on the same inventive concept, the embodiment of the invention also provides a structural schematic diagram of a display device, and the display device comprises the display panel. Exemplarily, fig. 14 is a schematic structural diagram of a display device according to an embodiment of the present invention, and as shown in fig. 14, the display device 200 includes the display panel 100.
The display device 200 provided by the embodiment of the invention can be any electronic product with a display function, including but not limited to the following categories: the present disclosure relates to a mobile phone, a television, a notebook computer, a desktop display, a tablet computer, and the like.
