Background technique

With the wide application of liquid crystal display devices in daily life, high resolution and narrow frame have become the current development trend of liquid crystal display devices. The driver of the liquid crystal display device mainly includes a data driver and a gate driver, wherein the gate driver can enable the liquid crystal display device to realize high resolution and narrow frame display. The gate drive circuit can be installed in the display panel through the chip on film (Chip On Film, COF for short) or the chip is attached to the glass substrate (Chip On Glass, COG for short), or can be installed in the display panel through the thin film transistor (Thin Film Transistor). A Film Transistor (TFT for short) constitutes an integrated circuit unit and is arranged in the display panel. The gate drive circuit is generally one electrode of the shift register connected to a gate line, and a signal is input to the gate line through the gate drive circuit, thereby realizing progressive scanning of pixels. Compared with the traditional COF or COG design, the gate driver can make the cost of the liquid crystal display device lower, reduce one process and increase the yield.

Due to the advantages of the touch display device (Touch Panel), which has the advantages of ease of use, multi-functionality of operation, ever-decreasing price and steadily increasing yield rate, etc., applications are becoming more and more popular. Touch display devices can be classified into plug-in touch display devices and built-in touch display devices. Among them, the in-cell touch display device is further divided into two types: an in-cell (In Cell) touch display device and an external (On Cell) touch display device.

When the gate driver is applied to an in-cell touch display device, the driving signal output by the gate driver will interfere with the touch signal, thereby affecting the touch function of the touch display device.

The working process of the shift register provided by this embodiment will be described in detail below with reference to FIGS. 3 to 5 .

In this embodiment, the shift registers can be cascaded to form a gate driving circuit. In this embodiment, the shift register can implement gate driving processes in two modes.

Figure 3 is a schematic diagram of the forward scan of the shift register in Figure 2 in the first mode, combined with Figure 2 and Figure 3, the first mode is a compatible mode, which is divided into pre-charging phase, output phase, reset phase and noise release phase.

In the pre-charging stage, the first switch tube M1 is turned on under the control of the input signal output from the signal input terminal Input (N), wherein the input signal output from the signal input terminal Input (N) is the output of the upper stage shift register The output signal output from the terminal Output(N-1), the output signal output from the output terminal Output(N-1) of the upper stage shift register is a high-level signal. The clock signal CLK output by the clock signal terminal is a low-level signal. Since the first switch tube M1 is turned on, the first power supply charges the capacitor C1 through the first switch tube M1, so that the voltage of the pull-up node PU is pulled up. At this time The voltage output by the first power supply is the voltage VDD, and the voltage VDD output by the first power supply is at a high level. The third switching tube M3 , the sixth switching tube M6 and the seventh switching tube M7 are turned on under the control of the voltage of the PU, and the voltage of the PU point is at a high level at this time. The seventh switching tube M7 is turned on, so that the voltage of the gate of the eighth switching tube M8 is the voltage VGL output by the third power supply, and the eighth switching tube M8 is turned off under the control of the voltage VGL output by the third power supply. The voltage VGL output by the three power supplies is at a low level. The sixth switch tube M6 is turned on, so that the voltage of the pull-down node PD is the voltage output by the third power supply. Since the voltage VGL output by the third power supply is at a low level, the voltage of the pull-down node PD is at a low level, and the fourth switch tube M4 and the tenth switch M10 are turned off under the control of the voltage of the pull-down node PD. The fifth switching tube M5 is turned off under the control of the voltage output by the switching power supply SW, and at this time the voltage output by the switching power supply SW is at a low level. The fourth switching tube M4, the fifth switching tube M5 and the tenth switching tube M10 are turned off, thereby ensuring the stable output of the signal at the output terminal Output.

In the output stage, the fifth switching tube M5 is turned off under the control of the voltage output by the switching power supply SW, and at this time the voltage output by the switching power supply SW is at a low level. The twelfth switching tube M12 is turned on under the control of the voltage of the pull-up node PU, the eleventh switching tube M11 is turned off under the control of the voltage output by the switching power supply SW, and the thirteenth switching tube M13 is turned on under the control of the voltage of the pull-up node PD. Closed under the control of the pull-down node PD output voltage is low at this time. At this time, the first switching tube M1 is turned off under the control of the input signal output by the signal input terminal Input (N), wherein the input signal output by the signal input terminal Input (N) is the output terminal Output ( The output signal output by N-1), the output signal output by the output terminal Output (N-1) of the shift register of the upper stage is a low-level signal. The voltage of the pull-up node PU remains at a high level, so the third switch M3 remains turned on under the control of the voltage of the pull-up node PU. At this time, since the clock signal output by the clock signal output terminal CLK is at a high level, the voltage of the pull-up node PU is amplified under the action of the bootstrapping effect (bootstrapping), and finally the driving signal is transmitted to the output terminal Output to achieve For the output terminal Output to output the driving signal. At this time, the sixth switch tube M6 and the seventh switch tube M7 are still in the on state under the control of the voltage at the PU point, so that the fourth switch tube M4 and the tenth switch tube M10 are still in the off state, and the fifth switch tube M10 is still in the off state. M5 is still in a closed state under the control of the voltage output by the switching power supply SW, thereby ensuring the stable output of the signal at the output terminal Output.

In the reset phase, the second switch tube M2 is turned on under the control of the reset signal output by the reset signal terminal RESET, wherein the reset signal output by the reset signal terminal RESET is the output terminal Output(N+1) of the next stage shift register The output signal output, the output signal output by the output terminal Output (N+1) of the shift register of the next stage is a high level signal. After the second switch tube M2 is turned on, the voltage of the pull-up node PU is pulled down to the voltage output by the second power supply under the influence of the voltage VSS output by the second power supply. level, the voltage of the pull-up node PU is at low level, so that the third switch M3, the sixth switch M6 and the seventh switch M7 are turned off. The ninth switching tube M9 and the eighth switching tube M8 are turned on under the control of the voltage VGH output by the fourth power supply, and the voltage VGH output by the fourth power supply is at a high level, so that the voltage of the pull-down node PD is pulled up, and the voltage of the pull-down node PD is pulled up. The voltage of PD is high level. The fourth switching tube M4 and the tenth switching tube M10 are turned on under the control of the pull-down node PD, so as to pull down the voltage of the pull-up node PU to the voltage VGL output by the third power supply through the tenth switching tube M10 and turn the output terminal Output The voltage of the third power supply is pulled down to the voltage VGL output by the third power supply through the fourth switch tube M4, and the voltage VGL output by the third power supply is at a low level.

In the noise release stage, the output terminal Output has no signal output, and the first switching tube M1 remains in a closed state. The eighth switch M8 and the ninth switch M9 are kept on, so that the voltage of the pull-down node PD remains at a high level when there is no signal output from the output terminal Output, the fourth switch M4 and the tenth switch M10 are turned on, and the fourth switch M4 and the tenth switch M10 are turned on. The tenth switch tube M10 continuously releases noise to the pull-up node PU, and the fourth switch tube M4 continuously releases noise to the output terminal Output. The above noise release process can eliminate the coupling noise (Coupling Noise) generated by the clock signal terminal, thereby The stability of the signal output is guaranteed.

Before the next frame is displayed, the gate shift register keeps repeating the noise-releasing stage and continuously performs noise-releasing processing. Before the display of the current frame picture ends and the arrival of the next frame picture, that is: in the V-Blank stage, the fifth switching tube M5 is turned on under the control of the voltage output by the switching power supply SW, and the output terminal Output is amplified. noise, at this time the voltage output by the switching power supply SW is at a high level. However, since the voltage of the pull-up node PU is at a low level, the twelfth switch M12 is turned off under the control of the voltage of the pull-up node PU, so that the eleventh switch M11 and the thirteenth switch M13 are also turned off. ; Since the voltage of the pull-down node PD is at a high level, the thirteenth switching transistor M13 is turned on under the control of the voltage of the pull-down node PD. When the thirteenth switching tube M13 is turned on, since the second pole of the thirteenth switching tube M13 is connected to the third power supply, and the voltage VGL output by the third power supply is at a low level, the thirteenth switching tube M13 will The eleventh switching tube M11 and the twelfth switching tube M12 are discharged to discharge excess charge, effectively reducing the coupling capacitance between the switching power supply SW and the pull-up node PU, and avoiding the voltage of the pull-up node PU of other rows The problem of affecting the display of other lines caused by pulling it high, thus improving the display quality. Among them, when the touch function needs to be performed, the touch process can also be realized in the vertical blanking stage. Since the output terminal Output is continuously denoised during the vertical blanking stage, the interference of the driving signal output by the output terminal on the touch signal can be avoided. . It can be known from the above content that the compatibility mode can be used in the vertical blanking mode in which touch is performed during the vertical blanking phase. In addition, when the display device does not perform the above-mentioned touch stage, the compatibility mode can also be used in a display mode that does not perform touch. In summary, the compatibility mode is compatible with the display mode and the vertical blanking mode, so the compatibility mode is compatible with the traditional gate driving mode and the vertical blanking gate driving mode of the in-cell touch. This stage is not specifically shown in the figure.

Fig. 4 is the schematic diagram that the shift register in Fig. 2 carries out forward scan in the second mode, in combination with Fig. 2 and Fig. 4, the second mode is the line blanking (H-Blank) mode, this mode Including pre-charging phase, touch phase, output phase, reset phase and noise release phase.

In the pre-charging stage, the first switch tube M1 is turned on under the control of the input signal output from the signal input terminal Input (N), wherein the input signal output from the signal input terminal Input (N) is the output of the upper stage shift register The output signal output from the terminal Output(N-1), the output signal output from the output terminal Output(N-1) of the upper stage shift register is a high-level signal. The clock signal CLK output by the clock signal terminal is a low-level signal. Since the first switch tube M1 is turned on, the first power supply charges the capacitor C1 through the first switch tube M1, so that the voltage of the pull-up node PU is pulled up. At this time The voltage output by the first power supply is the voltage VDD, and the voltage VDD output by the first power supply is at a high level. The third switching tube M3 , the sixth switching tube M6 and the seventh switching tube M7 are turned on under the control of the voltage of the PU, and the voltage of the PU point is at a high level at this time. The seventh switching tube M7 is turned on, so that the voltage of the gate of the eighth switching tube M8 is the voltage VGL output by the third power supply, and the eighth switching tube M8 is turned off under the control of the voltage VGL output by the third power supply. The voltage VGL output by the three power supplies is at a low level. The sixth switch tube M6 is turned on, so that the voltage of the pull-down node PD is the voltage VGL output by the third power supply. Since the voltage VGL output by the third power supply is at a low level, the voltage of the pull-down node PD is at a low level, and the fourth switch The transistor M4 and the tenth switching transistor M10 are turned off under the control of the voltage of the pull-down node PD. The fifth switching tube M5 is turned off under the control of the voltage output by the switching power supply SW, and at this time the voltage output by the switching power supply SW is at a low level. The fourth switching tube M4, the fifth switching tube M5 and the tenth switching tube M10 are turned off, thereby ensuring the stable output of the signal at the output terminal Output.

In the touch phase, that is, during the line blanking phase, the voltage of the pull-up node PU continues to maintain a high voltage, the twelfth switch tube M12 is turned on under the control of the voltage of the pull-up node PU, and the output voltage of the switching power supply SW is High level, the eleventh switching tube M11 is turned on under the control of the voltage output by the switching power supply SW; the thirteenth switching tube M13 is turned off under the control of the voltage of the pull-down node PD, and the voltage of the pull-down node PD is low. flat. The voltage output by the switching power supply SW is at a high level, and the fifth switching tube M5 is turned on under the control of the voltage output by the switching power supply SW, and noise is released to the output terminal Output (N), so that the output terminal Output (N) has no driving signal output, avoiding the interference of the driving signal on the touch signal, thereby ensuring the touch function. Since the eleventh switch M11 is turned on, the switching power supply SW can supplementally charge the pull-up node PU, so that the voltage of the pull-up node PU is at a high level and will not decrease. Since the switching power supply SW charges the pull-up node PU through only one switch tube of the eleventh switch tube M11 , the charging effect of the compensation module is good. Fig. 5 is a schematic diagram of no compensation for the pull-up node. As shown in Fig. 5, since the second switch M2 and the tenth switch M10 have electric leakage, if the pull-up node PU is not supplemented with charge, the pull-up node PU will be pulled down. The voltage of the pull-up node PU is pulled up, so that the voltage of the pull-up node PU decreases, so that there will be a problem of no driving signal output or too low output voltage of the driving signal after the touch is completed. Comparing the above-mentioned FIG. 4 and FIG. 5, it can be seen that after the supplementary charging of the pull-up node PU in FIG. 4, the voltage of the pull-up node PU is at a high level and will not decrease. At the same time, since the voltages of the pull-up nodes PU in the shift registers corresponding to other rows are all at low level, subsequent operations of the shift registers corresponding to other rows will not be affected.

In the output stage, the fifth switching tube M5 is turned off under the control of the voltage output by the switching power supply SW, and at this time the voltage output by the switching power supply SW is at a low level. The twelfth switching tube M12 is turned on under the control of the voltage of the pull-up node PU, and the eleventh switching tube M11 is turned off under the control of the voltage output by the switching power supply SW; is turned off under the control of , and the voltage of the pull-down node PD is at a low level at this time. At this time, the first switching tube M1 is turned off under the control of the input signal output by the signal input terminal Input (N), wherein the input signal output by the signal input terminal Input (N) is the output terminal Output ( The output signal output by N-1), the output signal output by the output terminal Output (N-1) of the shift register of the upper stage is a low-level signal. The voltage of the pull-up node PU remains at a high level, so the third switch M3 remains turned on under the control of the voltage of the pull-up node PU. At this time, since the clock signal output by the clock signal output terminal CLK is at a high level, the voltage of the pull-up node PU is amplified under the action of the bootstrapping effect (bootstrapping), and finally the driving signal is transmitted to the output terminal Output to achieve For the output terminal Output to output the driving signal. At this time, the sixth switch tube M6 and the seventh switch tube M7 are still in the on state under the control of the voltage at the PU point, so that the fourth switch tube M4 and the tenth switch tube M10 are still in the off state, and the fifth switch tube M10 is still in the off state. M5 is still in a closed state under the control of the voltage output by the switching power supply SW, thereby ensuring the stable output of the signal at the output terminal Output.

In the reset phase, the second switch tube M2 is turned on under the control of the reset signal output by the reset signal terminal RESET, wherein the reset signal output by the reset signal terminal RESET is the output terminal Output(N+1) of the next stage shift register The output signal output, the output signal output by the output terminal Output (N+1) of the shift register of the next stage is a high level signal. After the second switch tube M2 is turned on, the voltage of the pull-up node PU is pulled down to the voltage VSS output by the second power supply under the influence of the voltage output by the second power supply. level, the voltage of the pull-up node PU is at low level, so that the third switch M3, the sixth switch M6 and the seventh switch M7 are turned off. The ninth switching tube M9 and the eighth switching tube M8 are turned on under the control of the voltage VGH output by the fourth power supply, and the voltage VGH output by the fourth power supply is at a high level, so that the voltage of the pull-down node PD is pulled up, and the voltage of the pull-down node PD is pulled up. The voltage of PD is high level. The fourth switching tube M4 and the tenth switching tube M10 are turned on under the control of the pull-down node PD, so as to pull down the voltage of the pull-up node PU to the voltage output by the third power supply through the tenth switching tube M10 and the output terminal Output The voltage is pulled down to the voltage output by the third power supply through the fourth switch tube M4, and the voltage output by the third power supply is at a low level.

In the noise release stage, the output terminal Output has no signal output, and the first switching tube M1 remains in a closed state. The eighth switch M8 and the ninth switch M9 are kept on, so that the voltage of the pull-down node PD remains at a high level when there is no signal output from the output terminal Output, the fourth switch M4 and the tenth switch M10 are turned on, and the fourth switch M4 and the tenth switch M10 are turned on. The tenth switch tube M10 continuously releases noise on the pull-up node PU, and the fourth switch tube M4 continuously releases noise on the output terminal Output. The above noise release process can eliminate the coupling noise generated by the clock signal terminal, thus ensuring the signal output stability.

Before the next frame is displayed, the gate shift register keeps repeating the noise-releasing stage and continuously performs noise-releasing processing. Before the display of the current frame picture ends and the arrival of the next frame picture, that is, in the field blanking stage, the fifth switching tube M5 is turned on under the control of the voltage output by the switching power supply SW to release noise from the output terminal Output. At this time, the switch The voltage output by the power supply SW is at a high level. However, since the voltage of the pull-up node PU is at a low level, the twelfth switch M12 is turned off under the control of the voltage of the pull-up node PU, so that the eleventh switch M11 is also turned off. Since the voltage of the pull-down node PD is at a high level, the thirteenth switching transistor M13 is turned on under the control of the voltage of the pull-down node PD. When the thirteenth switching tube M13 is turned on, since the second pole of the thirteenth switching tube M13 is connected to the third power supply, and the voltage VGL output by the third power supply is at a low level, the thirteenth switching tube M13 will The eleventh switching tube M11 and the twelfth switching tube M12 are discharged to discharge excess charge, effectively reducing the coupling capacitance between the switching power supply SW and the pull-up node PU, and avoiding the voltage of the pull-up node PU of other rows The problem of affecting the display of other lines caused by pulling it high, thus improving the display quality. The row blanking mode can be applied to the gate driving mode of the row blanking of the in-cell touch. This stage is not specifically shown in the figure.

It should be noted that: as shown in FIG. 4 and FIG. 5 , the touch function is implemented in a certain line blanking stage in the display process, and then the display process continues. Take the first touch stage set between the first display scan stage and the second display scan stage in Figure 4 as an example for description. In the first display scan stage, perform the above precharge stage, and then enter the first In the row blanking stage after the display scan stage, the first touch stage is executed during the row blanking stage, and the second display scan stage is continued after the touch stage is completed, and the above output stage is executed in the second display scan stage , reset phase and noise release phase.

Specifically, when scanning in the forward direction, the voltage VDD output by the first power supply is at a high level, and the voltage VSS output by the second power supply is at a low level; when scanning in the reverse direction, the voltage VSS output by the first power supply is at a low level , the voltage VDD output by the second power supply is high level, the signal input terminal Input during forward scanning is used as the reset signal terminal RESET during reverse scanning, and the reset signal terminal RESET during forward scanning is used as reverse scanning When the signal input terminal Input.

The control pole of the second switch M2 is connected to the reset signal terminal RESET, the first pole of the second switch M2 is connected to the pull-up node PU, and the second pole of the second switch M2 is connected to the second power supply.

In this embodiment, the reset module 2 includes: a first switch M1 , a fourth switch M4 , a seventh switch M7 , an eighth switch M8 , a ninth switch M9 and a tenth switch M10 . The control pole of the first switch M1 is connected to the signal input terminal Input, the first pole of the first switch M1 is connected to the first power supply, and the second pole of the first switch M1 is connected to the pull-up node PU.

The connections of other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

In this embodiment, the shift registers can be cascaded to form a gate driving circuit. In this embodiment, the shift register can implement gate driving processes in two modes. The first mode is compatibility mode, which is divided into pre-charge phase, output phase, reset phase and noise release phase.

In the pre-charging stage, the second switch tube M2 is turned on under the control of the reset signal output by the reset signal terminal RESET, wherein the reset signal output by the reset signal terminal RESET is the output terminal Output(N+1 ), the output signal output by the output terminal Output(N+1) of the next stage shift register is a high level signal. The clock signal CLK output by the clock signal end is a low-level signal. Since the second switch M2 is turned on, the second power supply charges the capacitor C1 through the second switch M2, so that the voltage of the pull-up node PU is pulled up. At this time The voltage output by the second power supply is the voltage VDD, and the voltage VDD output by the second power supply is at a high level. For the working process of other structures in the pre-charging stage, refer to the first embodiment above, and will not be repeated here.

In the output stage, the second switching tube M2 is turned off under the control of the reset signal output by the reset signal terminal RESET, wherein the reset signal output by the reset signal terminal RESET is output by the output terminal Output(N+1) of the next stage shift register The output signal of the output signal output by the output terminal Output (N+1) of the shift register of the next stage is a low-level signal. For the working process of other structures in the output stage, reference may be made to the first embodiment above, and the description will not be repeated here.

In the reset phase, the first switching tube M1 is turned on under the control of the input signal output from the signal input terminal Input (N), wherein the input signal output from the signal input terminal Input (N) is the output terminal of the upper stage shift register The output signal output by Output(N-1), the output signal output by the output terminal Output(N-1) of the upper-stage shift register is a high-level signal. After the first switch tube M1 is turned on, the voltage of the pull-up node PU is pulled down to the voltage VSS output by the first power supply under the influence of the voltage output by the first power supply. level, the voltage of the pull-up node PU is at low level, so that the third switch M3, the sixth switch M6 and the seventh switch M7 are turned off. For the working process of other structures in the reset phase, reference may be made to the first embodiment above, and the description will not be repeated here.

For the working process of the reset stage, reference may be made to the first embodiment above, and the description will not be repeated here.

Before the next frame is displayed, the gate shift register keeps repeating the noise-releasing stage and continuously performs noise-releasing processing. Before the end of the display of the current frame picture and the arrival of the next frame picture, that is: in the field blanking stage, the fifth switching tube M5 is turned on under the control of the voltage output by the switching power supply SW to release noise from the output terminal Output. At this time, the switching power supply The voltage output by SW is high level. But because the voltage of the pull-up node PU is low level, the twelfth switch tube M12 is turned off under the control of the voltage of the pull-up node PU, so that the eleventh switch tube M11 is also turned off; is high level, the thirteenth switching transistor M13 is turned on under the control of the voltage of the pull-down node PD. Among them, when the touch function needs to be executed, the touch process can also be realized in the vertical blanking stage.

It can be seen from the above content that the compatibility mode can be used in the vertical blanking mode in which touch is performed during the vertical blanking phase. In addition, when the display device does not perform the above-mentioned touch stage, the compatibility mode can also be used in a display mode that does not perform touch. To sum up, the compatibility mode is compatible with the display mode and the vertical blanking mode, so the compatibility mode is compatible with the traditional gate driving mode and the vertical blanking gate driving mode of the in-cell touch.

The second mode is the line blanking mode, which includes a pre-charging phase, a touch phase, an output phase, a reset phase and a noise release phase. In this mode, the working process of the pre-charging phase, output phase, reset phase and noise release phase is the same as that of the first mode, and will not be repeated here. The difference between the touch control stage in this embodiment and the above-mentioned first embodiment is that: due to the leakage phenomenon of the first switch M1 and the tenth switch M10, it is necessary to supplementary charge the pull-up node PU, the rest of the description and embodiment One is the same, and will not be described again here.

At this time, the switch The voltage output by the power supply SW is at a high level. However, since the voltage of the pull-up node PU is at a low level, the twelfth switch M12 is turned off under the control of the voltage of the pull-up node PU, so that the eleventh switch M11 is also turned off. Since the voltage of the pull-down node PD is at a high level, the thirteenth switching transistor M13 is turned on under the control of the voltage of the pull-down node PD. When the thirteenth switching tube M13 is turned on, since the second pole of the thirteenth switching tube M13 is connected to the third power supply, and the voltage VGL output by the third power supply is at a low level, the thirteenth switching tube M13 will The eleventh switching tube M11 and the twelfth switching tube M12 are discharged to discharge excess charge, effectively reducing the coupling capacitance between the switching power supply SW and the pull-up node PU, and avoiding the voltage of the pull-up node PU of other rows The problem of affecting the display of other lines caused by pulling it high, thus improving the display quality.
