Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to fall within the scope of the present application.
Referring to fig. 1, fig. 1 is a schematic circuit diagram of a display panel according to an embodiment of the application. The display panel 1 includes a plurality of first scan lines 11 and a plurality of second scan lines 12 extending in a first direction D1 and alternately arranged at intervals, a plurality of first data lines 13 and a plurality of second data lines 14 extending in a second direction D2 and alternately arranged at intervals, first pixels 15 and second pixels 16 defined by intersections of the first scan lines 11 and the first data lines 13, third pixels 17 and fourth pixels 18 defined by intersections of the second scan lines 12 and the second data lines 14, and a driving circuit 19;
the driving circuit 19 transmits the first data signal transmitted by the first data line 13 to the first pixel 15 or the second pixel 16 under the control of the first scanning signal transmitted by the first scanning line 11, and the driving circuit 19 transmits the second data signal transmitted by the second data line 14 to the third pixel 17 or the fourth pixel 18 under the control of the second scanning signal transmitted by the second scanning line 12.
It should be noted that, in general, the display panel 1 includes a plurality of pixel units distributed in an array, and the driving circuit 19 electrically connected to the scanning lines of each row transmits the data signals on the data lines to the corresponding pixel units to realize the display of the picture.
In this embodiment, since the first scan signal transmitted on the first scan line 11 and the second scan signal transmitted on the second scan line 12 may be different, the first data signal transmitted on the first data line 13 and the second data signal transmitted on the second data line 14 may also be different, so as to independently control the operations of the first pixel 15, the second pixel 16, the third pixel 17 and the fourth pixel 18, and achieve different image display effects.
For example, the first scan signal may control the driving circuit 19 to turn on at a first frequency to enable the first pixel 15 or the second pixel 16 to display a picture at the first frequency, and the second scan signal may control the driving circuit 19 to turn on at a second frequency to enable the third pixel 17 or the fourth pixel 18 to display a picture at the first frequency; alternatively, the first data signal controls the first pixel 15 or the second pixel 16 to display at the first brightness, and the second data signal controls the third pixel 17 or the fourth pixel 18 to display at the second brightness, which is not limited in the present application.
Specifically, as shown in fig. 1, the driving circuit 19 omits to display black solid dots formed by intersecting the first scan line 11 and the first data line 13, and the second scan line 12 and the second data line 14 in fig. 1, the positions of the first pixel 15 and the third pixel 17 may be the same, and the positions of the second pixel 16 and the fourth pixel 18 may be the same, so as to reduce the occupied space of the display panel 1.
It can be appreciated that in the present embodiment, the first pixel 15 and the second pixel 16 are driven by the first scan line 11 and the first data line 13, and the third pixel 17 and the fourth pixel 18 are driven by the second scan line 12 and the second data line 14, so that the first pixel 15, the second pixel 16, the third pixel 17 and the fourth pixel 18 can be independently controlled, and the display modes of the display panel 1 are more diversified, so as to achieve the optimal display effect.
In one possible embodiment, please refer to fig. 2, fig. 2 is a schematic diagram of a driving circuit according to an embodiment of the present application. The driving circuit 19 includes a first switching unit T1, a first transistor diode P1, and a second transistor diode P2, wherein an anode of the first transistor diode P1 is electrically connected to a cathode of the second transistor diode P2 and the first switching unit T1, a cathode of the first transistor diode P1 is electrically connected to the first pixel 15 or the third pixel 17, an anode of the second transistor diode P2 is electrically connected to the second pixel 16 or the fourth pixel 18, the first switching unit T1 is turned on under the control of the first scan signal to transmit the first data signal to the first pixel 15 or the second pixel 16, and the first switching unit T1 is turned on under the control of the second scan signal to transmit the second data signal to the third pixel 17 or the fourth pixel 18.
It should be noted that, one end of the pixel unit in the display panel 1 is generally electrically connected to the common electrode 1a, so as to receive the common voltage, and when the voltage of the other end of the pixel unit in the display panel 1 is changed, the voltage of two ends of the pixel unit can be changed, thereby controlling the regulation of the pixel unit to light, or changing the light-emitting brightness of the pixel unit.
Specifically, as shown in fig. 2, one end of the first pixel 15 or the third pixel 17 is electrically connected to the common electrode 1a, and one end of the second pixel 16 or the fourth pixel 18 is electrically connected to the common electrode 1a, so that the voltage at the other end of the first pixel 15 or the third pixel 17 is changed, and the voltage at the other end of the second pixel 16 or the fourth pixel 18 is changed, so that the first pixel 15, the second pixel 16, the third pixel 17 and the fourth pixel 18 can be controlled.
In the present embodiment, the first data signal may be transferred to the first pixel 15 or the second pixel 16, and the second data signal may be transferred to the third pixel 17 or the fourth pixel 18 through the first transistor diode P1 and the second transistor diode P2. It is assumed that in an initial state, the voltage value of one end of the first pixel 15, the second pixel 16, the third pixel 17, and the fourth pixel 18 electrically connected to the first transistor P1 or the second transistor P2 is the same as the initial voltage value, and in general, the voltage value of the first data signal or the second data signal is not equal to the initial voltage value.
For example, when the gate of the first switching unit T1 is controlled by the first scan signal or the second scan signal such that the first data signal or the second data signal is transmitted to the drain of the first switching unit T1 through the source of the first switching unit T1, if the voltage value of the first data signal or the second data signal is greater than the initial voltage value, the first data signal or the second data signal can be transmitted to the first pixel 15 or the third pixel 17 through the first transistor diode P1; if the voltage value of the first data signal or the second data signal is smaller than the initial voltage value, the first data signal or the second data signal can be transmitted to the second pixel 16 or the fourth pixel 18 through the second transistor P2, so as to achieve the purpose of selectively charging two pixel units through one switching unit and two transistor diodes, thereby realizing independent control of the first pixel 15, the second pixel 16, the third pixel 17 and the fourth pixel 18.
It can be appreciated that, in the present embodiment, the first transistor diode P1 and the second transistor diode P2 are disposed at one side of the first switch unit T1, so that the leakage effect of the first switch unit T1 can be optimized, and the influence of the leakage current of the first switch unit T1 on the pixel units in the display panel 1 can be reduced.

It can be appreciated that the present embodiment is different from the previous embodiment in that, when the gate of the first switching unit T1 is controlled by the first scan signal or the second scan signal such that the first data signal or the second data signal is transmitted to the drain of the first switching unit T1 through the source of the first switching unit T1, if the voltage value of the first data signal or the second data signal is greater than the initial voltage value, the first data signal or the second data signal can be transmitted to the second pixel 16 or the fourth pixel 18 through the second transistor diode P2; if the voltage value of the first data signal or the second data signal is smaller than the initial voltage value, the first data signal or the second data signal can be transmitted to the first pixel 15 or the third pixel 17 through the first transistor diode P1, that is, the manner of selecting the transmission signal of the driving circuit 19 in the present embodiment is opposite to that in the previous embodiment.
It will be appreciated that in other possible embodiments, the driving circuit 19 may also implement that the first data signal or the second data signal is transmitted to the first pixel 15, the second pixel 16, the third pixel 17 and the fourth pixel 18 respectively in other embodiments, which the present application is not limited to.
In one possible embodiment, please refer to fig. 4, fig. 4 is a schematic diagram of a pixel circuit according to an embodiment of the present application. The first pixels 15 and the second pixels 16 are arranged at alternate intervals and staggered in the second direction D2.
Specifically, as shown in fig. 4, the first pixel 15 and the second pixel 16 are staggered by one pixel unit in the second direction D2, which is a possible way of electrically connecting the first pixel 15 and the second pixel 16 with the driving circuit 19 according to the present application, so that the space occupied by the driving circuit 19 for controlling the line connection of the first pixel 15 and the second pixel 16 respectively can be reduced.
It is to be understood that the first pixels 15 and the second pixels 16 may be disposed at alternate intervals in the second direction D2, or the third pixels 17 and the fourth pixels 18 may be disposed at alternate intervals in the second direction D2, which is not limited to this aspect of the application.

Specifically, as shown in fig. 5, the third pixels 17 and the fourth pixels 18 are alternately arranged at intervals in the first direction D1, and as a possible mode of electrically connecting the third pixels 17 and the fourth pixels 18 with the driving circuit 19 according to the present application, the space occupied by the driving circuit 19 for controlling the line connection of the first pixels 15 and the second pixels 16 respectively can be reduced.
It is to be understood that the third pixels 17 and the fourth pixels 18 may be alternately arranged at intervals in the first direction D1, or the first pixels 15 and the second pixels 16 may be alternately arranged at intervals in the first direction D1, which is not limited in the present application.
Specifically, as shown in fig. 1, the first pixels 15 and the second pixels 16 are multiplexed and are arranged at intervals alternately in the second direction D2, and the third pixels 17 and the fourth pixels 18 are arranged at intervals alternately in the first direction D1, so that the first scanning lines 11, the second scanning lines 12, the first data lines 13 and the second data lines 14 are electrically connected to the first pixels 15, the second pixels 16, the third pixels 17 and the fourth pixels 18 through the driving circuits 19, respectively, in a more compact manner, and the occupied space of the driving circuits 19 can be reduced to the maximum extent when the total area of the display panel 1 is fixed.
In one possible embodiment, please refer to fig. 6, fig. 6 is a schematic diagram of a display panel frame according to an embodiment of the present application. The display panel 1 further includes a first scan driving module 1b, a first data driving module 1c, a second scan driving module 1d, and a second data driving module 1e, where the first scan driving module 1b is electrically connected to the plurality of first scan lines 11, for generating the first scan signals, the first data driving module 1c is electrically connected to the plurality of first data lines 13, for generating the first data signals, the second scan driving module 1d is electrically connected to the plurality of second scan lines 12, for generating the second scan signals, and the second data driving module 1e is electrically connected to the plurality of second data lines 14, for generating the second data signals.
Specifically, the time and frequency of the first scan signal generated by the first scan driving module 1b and the second scan signal generated by the second scan driving module 1d may be different, and the voltage values of the first data signal generated by the first data driving module 1c and the second data signal generated by the second data driving module 1e may be different, so as to realize diversification of the display modes of the display panel 1.
For example, as shown in the dashed box portion of fig. 1, the dashed box portion has a total of 12 pixel units. The pixel units, the first scan lines 11 and the second scan lines 12 in the dashed frame are arranged in a row order from top to bottom, and the pixel units, the first data lines 13 and the second data lines 14 are arranged in a column order from left to right. When charging the pixel cells of the first row, it may be that the first scan driving module 1b generates the first scan signal and transmits the first data signal on the first scan line 11 of the first row, the first data driving module 1c generates the first data signal and transmits the first data signal on the first data line 13 of the first column and the second column to charge the pixel cells of the first row, the first column and the second column of the first row, the second scan driving module 1d generates the second scan signal and transmits the second data signal on the second scan line 12 of the first row, the second data driving module 1e generates the second data signal and transmits the second data signal on the second data line 14 of the second column to charge the pixel cells of the third column of the first row, and so on. It can be seen that the first scan driving module 1b may select to transmit the first scan signal on the different first scan lines 11, and the first data driving module 1c may select to transmit the first data signal on the different first data lines 13, so as to selectively control the first pixel or the second pixel to operate; the second scan driving module 1d selectively transmits the second scan signal on the different second scan lines 12, and the second data driving module 1e selectively transmits the second data signal on the different second data lines 14, so as to selectively control the third pixel or the fourth pixel to work, thereby realizing that the dual control system independently controls the first pixel 15, the second pixel 16, the third pixel 17 and the fourth pixel 18 respectively, so that the display modes of the display panel 1 are more diversified, and the optimal display effect is realized.
