[0002] In the field of display technology, display panels typically incorporate multiple driving circuits to power the pixel circuits within the display area. However, existing display panels often have a large number of driving circuits, which hinders both the achievement of narrow bezels and the reduction of power consumption. Therefore, a solution is urgently needed. Summary of the Invention

[0004] In a first aspect, embodiments of this application provide a driving circuit for driving a pixel circuit. The pixel circuit includes a driving transistor and a gate reset transistor, a data write transistor, and a threshold grabbing transistor electrically connected to the driving transistor. The driving circuit includes multiple cascaded shift register units. Each shift register unit includes a first type of signal output module and a second type of signal output module. The output terminal of the first type of signal output module is electrically connected to the gate of the gate reset transistor and / or the threshold grabbing transistor, and the output terminal of the second type of signal output module is electrically connected to the gate of the data write transistor.

[0005] Secondly, based on the same inventive concept, embodiments of this application provide a driving method for a driving circuit, used to drive the driving circuit as provided in the first aspect. The working process of the driving circuit includes a first type of enable signal output stage and a second type of enable signal output stage. The driving method includes:

[0006] During the first type of enable signal output stage, the first type of signal output module outputs an enable signal;

[0007] During the second type of enable signal output stage, the second type of signal output module outputs an enable signal;

Therefore, this application is intended to cover modifications and variations falling within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the embodiments provided in this application can be combined with each other without contradiction.

[0048] Figure 1 This is a plan view of a display panel provided in an embodiment of this application. Figure 2This is a partial schematic diagram of a shift register unit provided in an embodiment of this application.

[0049] This application provides a driving circuit 01 for driving a pixel circuit 02. For example... Figure 1 As shown, in one possible application scenario, both the driving circuit 01 and the pixel circuit 02 are disposed in the display panel 100. The display panel 100 includes a display area AA and a border area NA located around the display area AA. The border area NA can surround the display area AA.

[0050] The driving circuit 01 is located in the bezel area NA, and the pixel circuit 02 is located in the display area AA. The pixel circuit 02 is electrically connected to the light-emitting device 03 and is used to drive the light-emitting device 03 to emit light. The driving circuit 01 is also electrically connected to the pixel circuit 02 and is used to provide a gate scan signal to the pixel circuit 02, thereby driving the pixel circuit 02 to work.

[0051] The drive circuit 01 includes multiple cascaded shift register units 10, combined with Figure 2 As shown, the shift register unit 10 includes a first type of signal output module 11 and a second type of signal output module 12. The first type of signal output module 11 and the second type of signal output module 12 are used to transmit gate scan signals to different transistors in the pixel circuit 02.

[0052] like Figure 3 As shown, Figure 3 This is a schematic diagram of a pixel circuit provided in an embodiment of this application. The pixel circuit 02 includes a driving transistor Md and a gate reset transistor M1, a data writing transistor M2, and a threshold grabbing transistor M3 that are electrically connected to the driving transistor Md.

[0053] The driving transistor Md is used to generate the light-emitting driving current, the gate reset transistor M1 is used to transmit the reset voltage to the gate of the driving transistor Md, the data write transistor M2 is used to transmit the data voltage to the driving transistor Md, and the threshold grab transistor M3 is used to compensate the threshold voltage of the driving transistor Md to the gate of the driving transistor Md.

[0054] For example, such as Figure 3As shown, the first terminal of the gate reset transistor M1 is electrically connected to the first reset signal line SL1, the second terminal is electrically connected to the gate of the driving transistor Md, and the gate is electrically connected to the first scan line S1N. The first reset signal line SL1 transmits the first reset voltage Vref1. The first terminal of the data write transistor M2 is electrically connected to the data signal line DL1, the second terminal is electrically connected to the first terminal of the driving transistor Md, and the gate is electrically connected to the second scan line SP. The data signal line DL1 transmits the data voltage Data. The first terminal of the threshold grabbing transistor M3 is electrically connected to the second terminal of the driving transistor Md, the second terminal is electrically connected to the gate of the driving transistor Md, and the gate is electrically connected to the third scan line S2N.

[0055] In addition, pixel circuit 02 also includes a power supply voltage writing transistor M4, a light-emitting control transistor M5, a light-emitting reset transistor M6, and a storage capacitor Cst. The first terminal of the power supply voltage writing transistor M4 is electrically connected to the first power supply signal line DL2, the second terminal is electrically connected to the first terminal of the driving transistor Md, and the gate is electrically connected to the light-emitting control signal line EM. The first power supply signal line DL2 transmits the first power supply voltage PVDD. The first terminal of the light-emitting control transistor M5 is electrically connected to the second terminal of the driving transistor Md, the second terminal is electrically connected to the first terminal of the light-emitting device 03, and the gate is electrically connected to the light-emitting control signal line EM. The first terminal of the light-emitting reset transistor M6 is electrically connected to the second reset signal line SL2, the second terminal is electrically connected to the first terminal of the light-emitting device 03, and the gate is electrically connected to the second scan line SP. The second reset signal line SL2 transmits the second reset voltage Vref2. One plate of the storage capacitor Cst is electrically connected to the gate of the driving transistor Md, and the other plate is electrically connected to the first power supply signal line DL1.

[0056] For example, both the gate reset transistor M1 and the threshold grabbing transistor M3 are metal oxides. The gate reset transistor M1 and the threshold grabbing transistor M3 are N-type transistors, while the driving transistor Md, the data writing transistor M2, the power supply voltage writing transistor M4, the light-emitting control transistor M5, and the light-emitting reset transistor M6 are P-type transistors.

[0057] The operation of pixel circuit 02 can be the same as that of existing technology, and will not be described in detail here.

[0058] Among them, the output terminal SN_OUT of the first type of signal output module 11 is electrically connected to the gate of the gate reset transistor M1 and / or the gate of the threshold grabbing transistor M3, and the output terminal SP_OUT of the second type of signal output module 12 is electrically connected to the gate of the data writing transistor M2.

[0059] In other words, the first type of signal output module 11 can provide a scan signal to the gate of the gate reset transistor M1 via the first scan line S1N, and / or provide a scan signal to the gate of the threshold grabbing transistor M3 via the third scan line S2N. The second type of signal output module 12 can provide a scan signal to the gate of the data write transistor M2 via the second scan line SP. In the same pixel circuit 02, at least one of the gate reset transistor M1 and the threshold grabbing transistor M3 and the data write transistor M2 can be connected to the same shift register unit 10.

[0060] It should be noted that, Figure 3 This only illustrates the case where the gates of the first type of signal output module 11 are electrically connected to the gates of the gate reset transistor M1 and the threshold grabbing transistor M3.

[0061] The enable signal output by the output terminal SN_OUT of the first type of signal output module 11 can be a high-level signal, and the enable signal output by the output terminal SP_OUT of the second type of signal output module 12 can be a low-level signal.

[0062] In this embodiment, by configuring at least one of the gate reset transistor M1 and the threshold grabbing transistor M3 in the pixel circuit 02 to be electrically connected to the same driving circuit 01 as the data writing transistor M2, the number of peripheral driving circuits required for the pixel circuit 02 can be reduced. When the driving circuit 01 and the pixel circuit 02 are applied in the display panel 100, it is beneficial to reduce the area occupied by the peripheral driving circuits, thereby facilitating the achievement of a narrow bezel in the display panel 100.

[0063] Furthermore, reducing the number of peripheral driving circuits required for the pixel circuit 02 can also reduce the number of clock signals required for the peripheral driving circuits, which is beneficial for reducing the power consumption of the display panel 100.

[0064] Figure 4 This is a plan view of yet another display panel provided in an embodiment of this application. Figure 5 This is a partial schematic diagram of another shift register unit provided in an embodiment of this application.

[0065] In one embodiment of this application, combined with Figure 4 and Figure 5 As shown, the second type of signal output module 12 includes a first scan signal output module 121 and a second scan signal output module 122. The first scan signal output module 121 and the second scan signal output module 122 are electrically connected to the gates of the data writing transistors M2 in different row pixel circuits 02, respectively.

[0066] Optional, such as Figure 4As shown, the output terminal SP1_OUT of the first scan signal output module 121 is electrically connected to the i-th row pixel circuit 02, and the output terminal SP2_OUT of the second scan signal output module 122 is electrically connected to the (i+1)-th row pixel circuit 02; i≥1. That is, in the display panel 100, the same shift register unit 10 can drive the data writing transistor M2 in two adjacent rows of pixel circuits 02.

[0067] It should be noted that the output terminal SP1_OUT of the first scan signal output module 121 and the output terminal SP2_OUT of the second scan signal output module 122 can both be the output terminal SP_OUT of the second type of signal output module 12.

[0068] In this embodiment of the application, the same shift register unit 10 is set to drive two rows of pixel circuits 02, which can reduce the number of shift register units 10 in the driving circuit 01. While implementing the driving pixel circuit 02, it is beneficial to further reduce the area occupied by the driving circuit 01, thereby further reducing the bezel of the display panel 100.

[0069] Please continue to combine Figure 4 and Figure 5 In one embodiment of this application, the output terminal SN_OUT of the first type of signal output module 11 is electrically connected to at least two rows of pixel circuits 02.

[0070] For example, the output terminal SN_OUT of the first type of signal output module 11 is electrically connected to the two-row pixel circuit 02. That is, the same shift register unit 10 can drive the gate reset transistor M1 and / or threshold grabbing transistor M3 in the two-row pixel circuit 02.

[0071] In this embodiment, the output terminal SN_OUT of the first type of signal output module 11 is electrically connected to at least two rows of pixel circuits 02. This is beneficial because in the same shift register unit 10, the first type of signal output module 11 and the second type of signal output module 12 can drive the same number of rows of pixel circuits 02, thereby reducing the control difficulty of the shift register unit 101 and simplifying the control method of the drive circuit 01.

[0072] Figure 6 This is a schematic diagram of a shift register unit provided in an embodiment of this application.

[0073] In one embodiment of this application, such as Figure 6As shown, the first type of signal output module 11 includes a first output unit 11 and a second output unit 112. The input terminal of the first output unit 11 receives a first fixed potential signal, and its output terminal is electrically connected to the output terminal SN_OUT of the first type of signal output module 11. The input terminal of the second output unit 112 receives a second fixed potential signal, and its output terminal is electrically connected to the output terminal SN_OUT of the first type of signal output module 11.

[0074] For example, the first fixed potential signal is a high-level signal VGH, and the second fixed potential signal is a low-level signal VGL.

[0075] The shift register unit 10 further includes a first input module 13, a transmission module 14, and a gating module 15. The first input module 13 receives a first trigger signal SN_IN at its input terminal, is electrically connected to the first node N1 at its output terminal, and receives a first clock signal CK1 at its control terminal. The first type of signal output module 11 can output the signal required by the pixel circuit 02 in response to the first trigger signal SN_IN.

[0076] The cascading module 14 is electrically connected to the first node N1. The first output terminal of the cascading module 14 is electrically connected to the second node N2, and the second output terminal SN_NEXT is electrically connected to the gating module 15 and the second output unit 112. The first output terminal of the cascading module 14 transmits a control signal to the second node N2 in response to the potential of the first node N1, and the second output terminal SN_NEXT of the cascading module 14 transmits a control signal to the gating module 15 and the second output unit 112 in response to the potential of the second node N2.

[0077] The gating module 15 is electrically connected to the second node N2, and the output terminal of the gating module 15 is electrically connected to the first output unit 11. The gating module 15 transmits a control signal to the first output unit 11 in response to the potential of the second node N2 and the second output terminal SN_NEXT of the cascading module 14.

[0078] Optional, such as Figure 7 As shown, Figure 7 This is a schematic diagram of another shift register unit provided in an embodiment of this application. The cascading module 14 includes a first module 141 and a second module 142. The first input terminal of the first module 141 receives a first fixed potential signal VGH, the second input terminal receives a second fixed potential signal VGL, the output terminal is electrically connected to the second node N2, and the control terminal is electrically connected to the first node N1. The output terminal of the first module 141 can be the first output terminal of the cascading module 14.

The output terminal of the second module 142 can be equivalent to the second output terminal SN_NEXT of the cascade module 14, and the output terminal of the second module 142 is electrically connected to the gating module 15 and the second output unit 112.

[0080] For example, such as Figure 8 As shown, Figure 8 for Figure 7 The schematic diagram shows a shift register unit. The first input module 13 includes a first transistor T1. The first transistor T1 has a first terminal that receives a first trigger signal SN_IN, a second terminal that is electrically connected to a first node N1, and a gate that receives a first clock signal CK1. The first transistor T1 is used to transmit the first trigger signal SN_IN to the first node N1.

The first terminal of the third transistor T3 receives a second fixed potential signal VGL, its second terminal is electrically connected to the second node N2, and its gate is electrically connected to the first node N1. The second transistor T2 and the third transistor T3 have different channel types. The first module 141 transmits either the first fixed potential signal VGH or the second fixed potential signal VGL to the second node N2 in response to the potential of the first node N1.

[0082] For example, the second transistor T2 is a P-type transistor, and the third transistor T3 is an N-type transistor. The potential level of the second node N2 is opposite to the potential level of the first node N1.

[0083] The second module 142 includes a fourth transistor T4 and a fifth transistor T5. The first terminal of the fourth transistor T4 receives a first fixed potential signal VGH, its second terminal is electrically connected to the output terminal of the second module 142, and its gate is electrically connected to the second node N2. The channel type of the fourth transistor T4 is the same as that of the second transistor T2. The first terminal of the fifth transistor T5 receives a second fixed potential signal VGL, its second terminal is electrically connected to the output terminal of the second module 142, and its gate is electrically connected to the second node N2. The channel type of the fifth transistor T5 is the same as that of the third transistor T3. The second module 142 transmits either the first fixed potential signal VGH or the second fixed potential signal VGL to the gating module 15 and the second output unit 112 in response to the potential of the second node N2. The output potential level of the second module 142 is opposite to the potential level of the second node N2.

Figure 6 and Figure 7 The second type of signal output module 12 includes a first scan signal output module 121 and a second scan signal output module 122. The first scan signal output module 121 and the second scan signal output module 122 can be electrically connected to pixel circuits 02 in different rows.

[0085] The first scan signal output module 121 includes a third output unit 1211 and a fourth output unit 1212. The input terminal of the third output unit 1211 receives a first fixed potential signal VGH, the output terminal is electrically connected to the output terminal SP1_OUT of the first scan signal output module 121, and the control terminal is electrically connected to the second node N2. The input terminal of the fourth output unit 1212 receives a second clock signal CK2, and the output terminal is electrically connected to the output terminal SP1_OUT of the first scan signal output module 121.

[0086] The second scan signal output module 122 includes a fifth output unit 1221 and a sixth output unit 1222. The input terminal of the fifth output unit 1221 receives a first fixed potential signal VGH, its output terminal is electrically connected to the output terminal SP2_OUT of the second scan signal output module 122, and its control terminal is electrically connected to the second node N2. The input terminal of the sixth output unit 1222 receives a third clock signal CK3, and its output terminal is electrically connected to the output terminal SP2_OUT of the second scan signal output module 122.

[0087] The shift register unit 10 also includes a second input module 16. The input terminal of the second input module 16 receives the second trigger signal SP_IN, the output terminal is coupled to the control terminal of the fourth output unit 1212 and the control terminal of the sixth output unit 1222, and the control terminal receives the first clock signal CK1.

[0088] Based on this configuration, the first scan signal output module 121 responds to the potential of the second node N2 and the second trigger signal SP_IN by outputting either a first fixed potential signal VGH or a second clock signal CK2. The second scan signal output module 122 responds to the potential of the second node N2 and the second trigger signal SP_IN by outputting either a first fixed potential signal VGH or a third clock signal CK3. The first scan signal output module 121 and the second scan signal output module 122 can share the same control signal. While driving the multi-row pixel circuit 02, this helps to further reduce the number of transistors in the shift register unit 10, thereby facilitating the further realization of a narrow bezel on the display panel 100.

In response to the potential of the output terminal of the second input module 16, the ninth transistor T9 transmits the second clock signal CK2 to the output terminal SP1_OUT of the first scan signal output module 121. The channel type of the eighth transistor T8 is the same as that of the ninth transistor T9.

[0092] For example, both the eighth transistor T8 and the ninth transistor T9 are P-type transistors.

The control terminals of both the first voltage regulator module 17 and the second voltage regulator module 18 receive a fixed potential signal. During the operation of the shift register unit 10, the first voltage regulator module 17 and the second voltage regulator module 18 can be in the ON state.

[0098] Optional, such as Figure 9 As shown. The control terminals of both the first voltage regulator module 17 and the second voltage regulator module 18 receive the second fixed potential signal VGL.

[0099] For example, such as Figure 10 As shown, Figure 10 for Figure 9 The schematic diagram shows one possible shift register unit. The first voltage regulator module 17 includes a thirteenth transistor T13. The first terminal of the thirteenth transistor T13 is electrically connected to the output terminal of the second input module 16, the second terminal is electrically connected to the control terminal of the fourth output unit 1212, and the gate is electrically connected to the second fixed potential signal VGL. The second voltage regulator module 18 includes a fourteenth transistor T14. The first terminal of the fourteenth transistor T14 is electrically connected to the output terminal of the second input module 16, the second terminal is electrically connected to the control terminal of the sixth output unit 1222, and the gate is electrically connected to the second fixed potential signal VGL. Both the thirteenth transistor T13 and the fourteenth transistor T14 are P-type transistors.

[0100] In this embodiment, the first voltage regulator module 17 and the second voltage regulator module 18 are configured to stabilize the potential at the output terminal of the second input module 16. When the potential at the control terminal of the fourth output unit 1212 changes, the first voltage regulator module 17 can reduce the impact of this potential change on the potential at the output terminal of the second input module 16, thereby stabilizing the potential at the output terminal of the second input module 16. When the potential at the control terminal of the sixth output unit 1222 changes, the second voltage regulator module 18 can reduce the impact of this potential change on the potential at the output terminal of the second input module 16, thereby stabilizing the potential at the output terminal of the second input module 16. This, in turn, helps ensure the accuracy of the second trigger signal SP_IN potential output by the second input module 16.

[0101] Please continue to refer to this. Figure 6 , Figure 7 and Figure 9 In one embodiment of this application, the shift register unit 10 further includes a reset module 19. The input terminal of the reset module 19 receives a first fixed potential signal VGH, the output terminal is electrically connected to the first node N1, and the control terminal is electrically connected to the reset signal line RST. The reset module 19 transmits the first fixed potential signal VGL to the first node N1 in response to the signal on the reset signal line RET, thereby resetting the first node N1. Furthermore, the cascading module 14 can then be used to reset the output terminal SN_OUT of the first type of signal output module 11 and the output terminal SP_OUT of the second type of signal output module 12.

[0102] For example, such as Figure 8 and Figure 10 As shown, the reset module 19 includes a fifteenth transistor T15. The first terminal of the fifteenth transistor T15 receives the first fixed potential signal line VGH, the second terminal is electrically connected to the first node N1, and the gate is electrically connected to the reset signal line RST.

[0103] Optionally, at the start of operation of the shift register unit 10, the reset signal line RST transmits the enable signal to control the reset module 19 to turn on.

[0104] In this embodiment, when the shift register unit 10 is reset, the reset signal line RST transmits an enable signal to control the reset module 19 to turn on. The first node N1 receives the first fixed potential signal VGH and maintains a high level. The second transistor T2 in the cascade module 14 is turned off, and the third transistor T3 is turned on. The third transistor T3 transmits the second fixed potential signal VGL to the second node N2, and the second node N2 maintains a low level. The fourth transistor T4 is turned on, and the fifth transistor T5 is turned off. The fourth transistor T4 transmits the first fixed potential signal VGH to the second output terminal SN_NEXT of the cascade module 14, controlling the seventh transistor T7 to turn on. The seventh transistor T7 transmits the second fixed potential signal VGL to the output terminal SN_OUT of the first type of signal output module 11, thereby resetting the output terminal SN_OUT of the first type of signal output module 11. The eighth transistor T8 and the tenth transistor T10 are turned on. The eighth transistor T8 transmits the first fixed potential signal VGH to the output terminal SP1_OUT of the first scan signal output module 121, and the tenth transistor T10 transmits the first fixed potential signal VGH to the output terminal SP2_OUT of the second scan signal output module 122, thereby resetting the output terminals SP1_OUT of the first scan signal output module 121 and SP2_OUT of the second scan signal output module 122.

[0105] Figure 11 This is a schematic diagram of a cascaded shift register unit provided in an embodiment of this application.

[0106] In one embodiment of this application, such as Figure 11 As shown, the cascaded multiple shift register units 10 include a j-th stage shift register unit 10 and a (j+1)-th stage shift register unit 10. The second output terminal SN_NEXT of the cascade module 14 in the j-th stage shift register unit 10 is electrically connected to the input terminal of the first input module 13 in the (j+1)-th stage shift register unit 10. The output terminal SP2_OUT of the second scan signal output module 122 in the j-th stage shift register unit 10 is electrically connected to the input terminal of the second input module 16 in the (j+1)-th stage shift register unit 10, where j≥1.

[0107] Based on this configuration, the signal output from the second output terminal SN_NEXT of the intermediate transmission module 14 in the j-th stage shift register unit 10 can be used as the first trigger signal SN_IN of the (j+1)-th stage shift register unit 10. Similarly, the signal output from the output terminal SP2_OUT of the second scan signal output module 122 in the j-th stage shift register unit 10 can be used as the second trigger signal SP_IN of the (j+1)-th stage shift register unit 10.

[0108] Please continue to refer to this. Figure 8 and Figure 10In one embodiment of this application, the gating module 15 includes a sixteenth transistor T16 and a seventeenth transistor T17. The first terminal of the sixteenth transistor T16 receives a first fixed potential signal VGH, the second terminal is electrically connected to the control terminal of the first output unit 111, and the gate is electrically connected to the second node N2. The first terminal of the seventeenth transistor T17 is electrically connected to the gating signal line CTRL, the second terminal is electrically connected to the control terminal of the first output unit 111, and the gate is electrically connected to the second output terminal SN_NEXT of the cascading module 14. The second terminals of the sixteenth transistor T16 and the seventeenth transistor T17 can be the output terminals of the gating module 15.

[0109] In this embodiment, the sixteenth transistor T16 transmits a first fixed potential signal VGH to the control terminal of the first output unit 111 in response to the potential of the second node N2, and the seventeenth transistor T17 transmits a signal on the strobe signal line CTRL to the control terminal of the first output unit 111 in response to the potential of the second output terminal SN_NEXT of the cascade module 14.

[0110] For example, the sixteenth transistor T16 and the seventeenth transistor T17 are both P-type transistors.

[0111] When the selected signal line CTRL transmits a high-level signal, both the sixteenth transistor T16 and the seventeenth transistor T16 can only transmit high-level signals to the sixth transistor T6. The sixth transistor T6 remains off, and the output terminal SN_OUT of the first type of signal output module 11 maintains a low-level second fixed potential signal VGL. At this time, the second output terminal SN_NEXT of the cascade module 14 can output a normal cascade signal.

[0112] When the selected signal line CTRL transmits a low-level signal, the sixteenth transistor T16 and the seventeenth transistor T17 can transmit high and low levels to the sixth transistor T6, respectively. The sixth transistor T6 can remain in the on or off state, and the output terminal SN_OUT of the first type of signal output module 11 can output the scan signal normally. At this time, the second output terminal SN_NEXT of the transmission module 14 transmits a signal with the opposite level to the output terminal SN_OUT of the first type of signal output module 11.

[0113] Based on this configuration, the frequency of the enable signal output at the output terminal SN_OUT of the first type of signal output module 11 can be controlled by controlling the signal on the strobe signal line CTRL.

At this time, the second output terminal SN_NEXT of the cascade module 14 can output a normal cascade signal.

[0119] When the strobe signal line CTRL transmits a low-level signal, the low-level signal on the strobe signal line CTRL can be transmitted to the third node N3 through the eighteenth transistor T18. The sixteenth transistor T16 and the seventeenth transistor T16 can transmit high and low levels to the sixth transistor T6, respectively. The sixth transistor T6 can remain in the on or off state, and the output terminal SN_OUT of the first type of signal output module 11 can output the scan signal normally. At this time, the second output terminal SN_NEXT of the cascade module 14 transmits a signal with the opposite level to the output terminal SN_OUT of the first type of signal output module 11.

[0120] Based on this configuration, the frequency of the enable signal output at the output terminal SN_OUT of the first type of signal output module 11 can be controlled by controlling the signal on the strobe signal line CTRL.

[0161] In the second stage Z2, the first trigger signal SN_IN is low, the second trigger signal SP_IN is high, the first clock signal CK1 is high, the second clock signal CK2 is low, and the third clock signal CK3 is high. The first transistor T1 and the fourteenth transistor T14 are off, the first node N1 maintains the low potential of the previous stage, and the output of the fourteenth transistor T14 maintains the low potential of the previous stage.

The sixth transistor T6 is turned on, and the sixth transistor T6 outputs the high-level first fixed potential signal VGH to the output terminal SN_OUT of the first type of signal output module 11.

[0163] In the third stage Z3, the first trigger signal SN_IN is high, the second trigger signal SP_IN is high, the first clock signal CK1 is high, the second clock signal CK2 is high, and the third clock signal CK3 is low.

[0164] The second node N2 maintains the high level potential of the previous stage. The fourth transistor T4, the sixteenth transistor T16, the eighth transistor T8, and the tenth transistor T10 are turned off, and the fifth transistor T5 is turned on. The fifth transistor T5 transmits the low-level second fixed potential signal VGL to the gates of the seventh transistor T7 and the seventeenth transistor T17. The seventh transistor T7 is turned off, and the seventeenth transistor T17 is turned on. The seventeenth transistor T17 transmits the low-level signal transmitted by the strobe signal line CTRL to the gate of the sixth transistor T6. The sixth transistor T6 is turned on, and the sixth transistor T6 outputs the high-level first fixed potential signal VGH to the output terminal SN_OUT of the first type of signal output module 11.

[0165] In the fourth stage Z4, the first trigger signal SN_IN is high, the second trigger signal SP_IN is high, the first clock signal CK1 is high, the second clock signal CK2 is high, and the third clock signal CK3 is high. The first transistor T1 and the fourteenth transistor T14 remain off. The first node N1 maintains the low potential of the previous stage, and the output of the fourteenth transistor T14 maintains the low potential of the previous stage.

[0166] The second node N2 maintains the high level potential of the previous stage. The fourth transistor T4, the sixteenth transistor T16, the eighth transistor T8, and the tenth transistor T10 are turned off, and the fifth transistor T5 is turned on.

The sixth transistor T6 is turned on, and the sixth transistor T6 outputs the high-level first fixed potential signal VGH to the output terminal SN_OUT of the first type of signal output module 11.

[0167] It should be noted that, in some other embodiments, the timing of the first trigger signal SN_IN and the second trigger signal SP_IN can be controlled to ensure that the time period during which the output terminal SN_OUT of the first type of signal output module 11 outputs the enable signal does not overlap with the time period during which the output terminal SP_OUT of the second type of signal output module 12 outputs the enable signal. This allows the gate reset transistor M1 in the pixel circuit 02 to be driven independently, thereby resetting the gate of the driving transistor Md in the pixel circuit 02.

[0168] Figure 18 This is a connection diagram of a shift register unit provided in an embodiment of this application.

[0169] In one embodiment of this application, such as Figure 18 As shown, the shift register unit 10 is electrically connected to the first fixed potential signal line XL1, the second fixed potential signal line XL2, and the strobe signal line CTRL. The first fixed potential signal line XL1 transmits the first fixed potential signal VGH, and the second fixed potential signal line XL2 transmits the second fixed potential signal VGL. The strobe signal line CTRL can transmit a low-level signal or a high-level signal according to control requirements.

[0170] In addition, the shift register unit 10 is connected to multiple clock signal lines, which are used to provide clock signals to the shift register unit 10. Figure 10 and Figure 18 As shown, in the odd-level shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the first clock signal line CLK1, the input terminal of the fourth output unit 1212 is electrically connected to the second clock signal line CLK2, and the input terminal of the sixth output unit 1222 is electrically connected to the third clock signal line CLK3.

[0171] Specifically, the clock signal transmitted via the first clock signal line CLK1 serves as the first clock signal CK1 received by the odd-level shift register unit 10. The clock signal transmitted via the second clock signal line CLK2 serves as the second clock signal CK2 received by the odd-level shift register unit 10. The clock signal transmitted via the third clock signal line CLK3 serves as the third clock signal CK3 received by the odd-level shift register unit 10.

[0172] In the even-level shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the third clock signal line CLK3, the input terminal of the fourth output unit 1212 is electrically connected to the fourth clock signal line CLK4, and the input terminal of the sixth output unit 1222 is electrically connected to the first clock signal line CLK1.

The clock signal transmitted via the fourth clock signal line CLK4 serves as the second clock signal CK2 received by the even-stage shift register unit 10. The clock signal transmitted via the first clock signal line CLK1 serves as the third clock signal CK3 received by the even-stage shift register unit 10.

[0174] For example, such as Figure 19 As shown, Figure 19The timing diagram of a clock signal line provided in this application embodiment shows that the first clock signal line CLK1, the second clock signal line CLK2, the third clock signal line CLK3, and the fourth clock signal line CLK4 sequentially transmit low-level signals.

[0175] In this embodiment, a first clock signal line CLK1, a second clock signal line CLK2, a third clock signal line CLK3, and a fourth clock signal line CLK4 are configured to transmit clock signals to the shift register unit 10 in the driving circuit 01. The shift register unit 10 in the driving circuit 01 can include only two ways of connecting the clock signal lines, which helps to reduce the complexity of connecting the shift register unit 10 to the clock signal lines in the driving circuit 01 and simplifies the connection structure of the driving circuit 01.

[0176] Figure 20 This is a connection diagram of another shift register unit provided in an embodiment of this application.

[0177] In one embodiment of this application, combined with Figure 10 and Figure 20 As shown, the shift register unit 10 is connected to multiple clock signal lines. In the j-th stage shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the first clock signal line CLK1, the input terminal of the fourth output unit 1212 is electrically connected to the second clock signal line CLK2, and the input terminal of the sixth output unit 1222 is electrically connected to the third clock signal line CLK3.

[0178] Specifically, the clock signal transmitted via the first clock signal line CLK1 serves as the first clock signal CK1 received by the j-th stage shift register unit 10. The clock signal transmitted via the second clock signal line CLK2 serves as the second clock signal CK2 received by the j-th stage shift register unit 10. The clock signal transmitted via the third clock signal line CLK3 serves as the third clock signal CK3 received by the j-th stage shift register unit 10.

[0179] In the (j+1)th level shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the third clock signal line CLK3, the input terminal of the fourth output unit 1212 is electrically connected to the first clock signal line CLK1, and the input terminal of the sixth output unit 1222 is electrically connected to the second clock signal line CLK2.

[0180] The clock signal transmitted via the third clock signal line CLK3 serves as the first clock signal CK1 received by the (j+1)th stage shift register unit 10. The clock signal transmitted via the first clock signal line CLK1 serves as the second clock signal CK2 received by the (j+1)th stage shift register unit 10. The clock signal transmitted via the second clock signal line CLK2 serves as the third clock signal CK3 received by the (j+1)th stage shift register unit 10.

[0181] In the (j+2)th level shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the second clock signal line CLK2, the input terminal of the fourth output unit 1212 is electrically connected to the third clock signal line CLK3, and the input terminal of the sixth output unit 1222 is electrically connected to the first clock signal line CLK1. j≥1.

The clock signal transmitted via the first clock signal line CLK1 serves as the third clock signal CK3 received by the (j+2)th stage shift register unit 10.

[0183] For example, such as Figure 19 As shown, the first clock signal line CLK1, the second clock signal line CLK2, and the third clock signal line CLK3 transmit low-level signals in sequence.

[0184] In this embodiment, the driving circuit 01 can be connected to only three clock signal lines to meet the clock signal requirements of each shift register unit 10. On the one hand, this reduces the number of clock signal lines connected to the driving circuit 01, saving energy. On the other hand, it makes the load of clock signal transmission on the first clock signal line CLK1, the second clock signal line CLK2, and the third clock signal line CLK3 more balanced, which helps to reduce the signal output difference of the shift register units caused by the uneven load of the clock signal lines.

[0185] Figure 21 This is a connection diagram of another shift register unit provided in an embodiment of this application.

[0186] In yet another embodiment of this application, combined with Figure 10 and Figure 21As shown, the shift register unit 10 is connected to multiple clock signal lines. In the j-th stage shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the first clock signal line CLK1, the input terminal of the fourth output unit 1212 is electrically connected to the second clock signal line CLK2, and the input terminal of the sixth output unit 1222 is electrically connected to the third clock signal line CLK3.

[0187] Specifically, the clock signal transmitted via the first clock signal line CLK1 serves as the first clock signal CK1 received by the j-th stage shift register unit 10. The clock signal transmitted via the second clock signal line CLK2 serves as the second clock signal CK2 received by the j-th stage shift register unit 10. The clock signal transmitted via the third clock signal line CLK3 serves as the third clock signal CK3 received by the j-th stage shift register unit 10.

[0188] In the (j+1)th level shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the third clock signal line CLK3, the input terminal of the fourth output unit 1212 is electrically connected to the fourth clock signal line CLK4, and the input terminal of the sixth output unit 1222 is electrically connected to the fifth clock signal line CLK5.

[0189] Specifically, the clock signal transmitted via the third clock signal line CLK3 serves as the first clock signal CK1 received by the (j+1)th stage shift register unit 10. The clock signal transmitted via the fourth clock signal line CLK4 serves as the second clock signal CK2 received by the (j+1)th stage shift register unit 10. The clock signal transmitted via the fifth clock signal line CLK5 serves as the third clock signal CK3 received by the (j+1)th stage shift register unit 10.

[0190] In the (j+2)th level shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the fifth clock signal line CLK5, the input terminal of the fourth output unit 1212 is electrically connected to the first clock signal line CLK1, and the input terminal of the sixth output unit 1222 is electrically connected to the second clock signal line CLK2.

[0191] Specifically, the clock signal transmitted via the fifth clock signal line CLK5 serves as the first clock signal CK1 received by the (j+2)th stage shift register unit 10. The clock signal transmitted via the first clock signal line CLK1 serves as the second clock signal CK2 received by the (j+2)th stage shift register unit 10. The clock signal transmitted via the second clock signal line CLK2 serves as the third clock signal CK3 received by the (j+2)th stage shift register unit 10.

[0192] In the (j+3)th level shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the second clock signal line CLK2, the input terminal of the fourth output unit 1212 is electrically connected to the third clock signal line CLK3, and the input terminal of the sixth output unit 1222 is electrically connected to the fourth clock signal line CLK4.

[0193] Specifically, the clock signal transmitted via the second clock signal line CLK2 serves as the first clock signal CK1 received by the (j+3)th stage shift register unit 10. The clock signal transmitted via the third clock signal line CLK3 serves as the second clock signal CK2 received by the (j+3)th stage shift register unit 10. The clock signal transmitted via the fourth clock signal line CLK4 serves as the third clock signal CK3 received by the (j+3)th stage shift register unit 10.

[0194] In the (j+4)th level shift register unit 10, the control terminals of the first input module 13 and the second input module 16 are electrically connected to the fourth clock signal line CLK4, the input terminal of the fourth output unit 1212 is electrically connected to the fifth clock signal line CLK5, and the input terminal of the sixth output unit 1222 is electrically connected to the first clock signal line CLK1. j≥1.

[0195] Specifically, the clock signal transmitted via the fourth clock signal line CLK4 serves as the first clock signal CK1 received by the (j+4)th stage shift register unit 10. The clock signal transmitted via the fifth clock signal line CLK5 serves as the second clock signal CK2 received by the (j+4)th stage shift register unit 10. The clock signal transmitted via the first clock signal line CLK1 serves as the third clock signal CK3 received by the (j+4)th stage shift register unit 10.

[0196] For example, such as Figure 22 As shown, Figure 22 The timing diagram of another clock signal line provided in this application embodiment shows that the first clock signal line CLK1, the second clock signal line CLK2, the third clock signal line CLK3, the fourth clock signal line CLK4 and the fifth clock signal line CLK5 sequentially transmit low-level signals.

[0197] In this embodiment, the driving circuit 01 can be connected to only five clock signal lines. While ensuring that the number of clock signal lines connected to the driving circuit 01 is small, the load of the clock signal transmitted by the first clock signal line CLK1, the second clock signal line CLK2, the third clock signal line CLK3, the fourth clock signal line CLK4, and the fifth clock signal line CLK5 is more balanced, which helps to reduce the signal output difference of the shift register unit caused by the unbalanced load of the clock signal lines.

[0198] Figure 23This is a connection diagram of another shift register unit provided in an embodiment of this application. Figure 24 for Figure 23 A timing diagram of the output signals of each type I signal output module in the multiple shift register units shown.

[0199] In one embodiment of this application, such as Figure 8 and Figures 10-16 As shown, the gating module 15 is electrically connected to the gating signal line CTRL, and the gating module 15 also transmits a control signal to the first output unit 111 in response to the signal on the gating signal line CTRL.

[0200] For example, such as Figure 8 and Figure 10 As shown, the first terminal of the seventeenth transistor T17 in the gating module 15 is electrically connected to the gating signal line CTRL. The seventeenth transistor T17 can transmit the signal on the gating signal line CTRL to the control terminal of the first output unit 111.

[0201] Combination Figure 23 and Figure 24 As shown, the driving circuit 01 is electrically connected to at least two gating signal lines CTRL, including a first gating signal line CTRL1 and a second gating signal line CTRL2. The cascaded multiple shift register units 10 include a first-region shift register unit 101, a second-region shift register unit 102, and a third-region shift register unit 103, with the second-region shift register unit 102 located between the first-region shift register unit 101 and the third-region shift register unit 103. The first-region shift register unit 101, the second-region shift register unit 102, and the third-region shift register unit 103 can sequentially output scan signals.

[0202] The first shift register unit 101 and the third shift register unit 103 are both electrically connected to the first strobe signal line CTRL1, and the second shift register unit 102 is electrically connected to the second strobe signal line CTRL2.

[0203] The first-level shift register unit 101 includes a final-level shift register unit 101B, which is a first-level shift register unit in the first-level shift register unit 101 that is closest to the second-level shift register unit 102. The third-level shift register unit 103 includes a first-level shift register unit 103A, which is a first-level shift register unit in the third-level shift register unit 103 that is closest to the second-level shift register unit 102.

[0204] During one operating cycle of the driving circuit 01, in the final stage shift register unit 101B of the first zone shift register unit 101, the enable signal output by the output terminal SN_OUT of the first type of signal output module 11 is the first enable signal XH1. In the first stage shift register unit 103A of the third zone shift register unit 103, the enable signal output by the output terminal SN_OUT of the first type of signal output module 11 is the second enable signal XH2.

[0205] It should be noted that within one operating cycle of the driving circuit 01, when the output terminal SN_OUT of the first type of signal output module 11 outputs multiple enable signals consecutively, in the final stage shift register unit 101B of the first zone shift register unit 101, the last enable signal output by the output terminal SN_OUT of the first type of signal output module 11 is the first enable signal XH1. In the first stage shift register unit 103A of the third zone shift register unit 103, the first enable signal output by the output terminal SN_OUT of the first type of signal output module 11 is the second enable signal XH2.

[0206] Specifically, the second enable signal XH2 is output after the first enable signal XH1 has finished outputting. There is a gap N between the start time of the second enable signal XH2 and the end time of the first enable signal XH1.

[0207] In other words, in the first-zone shift register unit 101 and the third-zone shift register unit 103 that are electrically connected to the same first strobe signal line CTRL1, there is a gap N between the last enable signal output by the first-zone shift register unit 101 and the first enable signal output by the third-zone shift register unit 103.

[0208] In this embodiment, the signal on the first strobe signal line CTRL1 can be set to change during the time interval N. While realizing the partition control of the first zone shift register unit 101 and the third zone shift register unit 101, and thus realizing the partition refresh of the display panel 100, it can avoid the situation where the output signal of the first type of signal output module 11 in the first zone shift register unit 101 and the third zone shift register unit 101 is incomplete, which is beneficial to improving the picture quality of the partition display of the display panel 100.

[0209] For example, such as Figure 25 As shown, Figure 25 for Figure 23The diagram shows another timing diagram of the output signals of each first-type signal output module in the multiple shift register units. Within one working cycle of the driving circuit 01, the second strobe signal line CTRL2 transmits a low-level signal, and the first strobe signal line CTRL1 first transmits a low-level signal, then a high-level signal. During the interval N, the signal on the first strobe signal line CTRL1 changes from low to high. This allows each first-type signal output module 11 in the first-zone shift register unit 101 to fully output enable signals while simultaneously preventing each first-type signal output module 11 in the third-zone shift register unit 101 from outputting enable signals, thereby achieving zoned refresh of the display panel 100.

[0210] It should be noted that, in the aforementioned embodiments, the gating module 15 includes a structure comprising a sixteenth transistor T16, a seventeenth transistor T17, and an eighteenth transistor T18, as follows: Figures 12-16 The shift register unit shown can also be connected to a single strobe signal line CTRL to achieve partitioned refresh of the display panel 100.

[0211] by Figure 12 Taking the shift register unit 10 as an example, when the signal on the strobe signal line CTRL changes from low to high, if the first type of signal output module 11 in a certain shift register unit is outputting a high-level signal, as can be seen from the aforementioned signal output process of the shift register, at this time, the second node N2 is at a high level, the eighteenth transistor T18 is turned off, and the high-level signal on the strobe signal line CTRL will not be written to the third node N3. Only after the first type of signal output module 11 in that shift register unit completes its high-level output and changes back to a low level will the high-level signal on the strobe signal line CTRL be written to the third node N3. This prevents the output signal SN_OUT of the first type of signal output module 11 in each shift register unit 10 from being incomplete.

[0212] Figure 26 This is a schematic diagram of another shift register unit provided in an embodiment of this application.

[0213] In one embodiment of this application, such as Figure 26 As shown, the second type of signal output module 12 includes a first scan signal output module 121 and a second scan signal output module 122. The first scan signal output module 121 and the second scan signal output module 122 can be electrically connected to pixel circuits 02 in different rows.

[0214] The first scan signal output module 121 includes a third output unit 1211 and a fourth output unit 1212. The input terminal of the third output unit 1211 receives a first fixed potential signal VGH, the output terminal is electrically connected to the output terminal SP1_OUT of the first scan signal output module 121, and the control terminal is electrically connected to the second node N2. The input terminal of the fourth output unit 1212 receives a second clock signal CK2, and the output terminal is electrically connected to the output terminal SP1_OUT of the first scan signal output module 121.

[0215] The second scan signal output module 122 includes a fifth output unit 1221 and a sixth output unit 1222. The input terminal of the fifth output unit 1221 receives a first fixed potential signal VGH, its output terminal is electrically connected to the output terminal SP2_OUT of the second scan signal output module 122, and its control terminal is electrically connected to the second node N2. The input terminal of the sixth output unit 1222 receives a third clock signal CK3, and its output terminal is electrically connected to the output terminal SP2_OUT of the second scan signal output module 122.

[0216] The shift register unit 10 also includes a second input module 16. The input terminal of the second input module 16 is electrically connected to the second output terminal SN_NEXT of the cascade module 15, and the output terminal is coupled to the control terminal of the fourth output unit 1212 and the control terminal of the sixth output unit 1222. The control terminal receives the first clock signal CK1.

[0217] Figure 26 The shift register circuit shown is Figure 10 The difference in the shift register circuit shown lies in the fact that the input terminal of the second input module 16 is electrically connected to the second output terminal SN_NEXT of the cascade module 15. The second trigger signal SP_IN received by the second input module 16 can be the signal output by the second output terminal SN_NEXT of the cascade module 15.

[0218] As can be seen from the signal output process of the shift register unit 10, in the signal output stage Z of the shift register unit 10, the fourth transistor T4 is turned off, and the signal potential output by the fifth transistor T5 is opposite to the level of the output terminal SN_OUT of the first type of signal output module 11. That is, in the signal output stage Z of the shift register unit 10, the second output terminal SN_NEXT of the cascade module 15 outputs a low-level signal. This is equivalent to the second output terminal SN_NEXT of the cascade module 15 providing a low-level signal to the second input module 16 in the first stage Z1. According to the working process of the second stage Z2, the third stage Z3, and the fourth stage Z4, the potential received by the input terminal of the second input module 16 will not affect the signal output of the output terminal SP1_OUT of the first scan signal output module 121 and the output terminal SP2_OUT of the second scan signal output module 122.

[0219] The embodiments of this application can increase the structural diversity of the shift register unit 10 and help reduce the number of cascade lines between the shift register units 10, thus saving costs.

[0220] Figure 27 This is a schematic diagram of another shift register unit provided in an embodiment of this application.

[0221] In one embodiment of this application, such as Figure 27 As shown, the shift register unit 10 also includes a third voltage regulator module 20. The input terminal of the third voltage regulator module receives a first fixed potential signal VGH, the output terminal is electrically connected to the output terminal of the second input module 16, and the control terminal is electrically connected to the second node N2. The third voltage regulator module 20 can transmit a high-level first fixed potential signal VGH to the output terminal of the second input module 16 in response to the potential of the second node N2.

[0222] For example, such as Figure 27 As shown, the third voltage regulator module 20 includes a transistor Tx. The first terminal of transistor Tx receives a first fixed potential signal VGH, the second terminal is electrically connected to the output terminal of the second input module 16, and the gate is electrically connected to the second node N3. Transistor Tx is a P-type transistor.

[0223] In this embodiment, during the period when the output terminal of the second input module 16 outputs a high level, the third voltage regulator module 20 can be controlled to turn on, so that the third voltage regulator module 20 transmits the high-level first fixed potential signal VGH to the output terminal of the second input module 16, thereby improving the potential stability of the output terminal of the second input module 16. This can stabilize the control terminals of the fourth output unit 1212 and the sixth output unit 1222 to a high potential, which is beneficial to improve the coupling effect of the second clock signal CK2 on the control terminal of the fourth output unit 1212 and the coupling effect of the third clock signal CK3 on the control terminal of the sixth output unit 1222.

[0224] Figure 28 A flowchart of a driving method provided in an embodiment of this application.

[0225] This application embodiment also provides a driving method for driving the driving circuit 01 provided in the above embodiments. The circuit structure of the driving circuit 01 can be as follows: Figure 8 , Figure 10 , Figures 12-16 , Figures 26-27 As shown. The operation of the drive circuit 01 includes a first type of enable signal output stage and a second type of enable signal output stage, as follows. Figure 28 As shown, the driving method includes:

[0226] Step B1: In the first type of enable signal output stage, the first type of signal output module outputs an enable signal.

[0227] Step B2: In the second type of enable signal output stage, the second type of signal output module outputs an enable signal.

[0228] Wherein, the first type of enable signal output stage and the second type of enable signal output stage do not overlap, or the second type of enable signal output stage is located within the first type of enable signal output stage.

[0229] For example, in the driving circuit 01, if the output terminal SN_OUT of the first type of signal output module 11 is only electrically connected to the gate reset transistor M1 in the pixel circuit 02, then in one working cycle of the driving circuit 01, the first type of enable signal output stage and the second type of enable signal output stage can be non-overlapping. The driving circuit 01 can first drive the pixel circuit 02 to complete the gate reset operation of the driving transistor Md, and then drive the pixel circuit 02 to perform the data signal writing operation.

[0230] If the output terminal SN_OUT of the first type signal output module 11 is only electrically connected to the threshold grabbing transistor M3 in the pixel circuit 02, then in one working cycle of the driving circuit 01, the second type enable signal output stage can be located within the first type enable signal output stage. When the driving circuit 01 drives the data writing transistor M2 in the pixel circuit 02 to turn on, it simultaneously drives the threshold grabbing transistor M3 to turn on, so as to ensure that the data signal can be written to the gate of the driving transistor Md.

[0231] Furthermore, if the output terminal SN_OUT of the first type of signal output module 11 is electrically connected to both the gate reset transistor M1 and the threshold grabbing transistor M3 in the pixel circuit 02, then the driving circuit 01 may include multiple first type of enable signal output stages. In one operating cycle of the driving circuit 01, some first type of enable signal output stages do not overlap with second type of enable signal output stages to ensure that the driving pixel circuit 02 completes the gate reset operation of the driving transistor Md. Some first type of enable signal output stages include second type of enable signal output stages to ensure that the driving pixel circuit 02 completes the data signal writing operation.

[0232] In this embodiment, at least one of the gate reset transistor M1 and the threshold grabbing transistor M3 in the pixel circuit 02 is electrically connected to the same driving circuit 01 as the data writing transistor M2. That is, the driving circuit 01 can simultaneously drive at least one of the gate reset transistor M1 and the threshold grabbing transistor M3 in the pixel circuit 02, as well as the data writing transistor M2. This reduces the number of peripheral driving circuits required for the pixel circuit 02. When the driving circuit 01 and the pixel circuit 02 are applied in the display panel 100, it is beneficial to reduce the area occupied by the peripheral driving circuits, thereby facilitating the achievement of a narrow bezel in the display panel 100.

[0233] Furthermore, reducing the number of peripheral driving circuits required for the pixel circuit 02 can also reduce the number of clock signals required for the peripheral driving circuits, which is beneficial for reducing the power consumption of the display panel 100.

[0234] In one embodiment of this application, such as Figure 8 , Figure 10 , Figures 12-16 , Figures 26-27 As shown, the second type of signal output module 12 includes a first scan signal output module 121 and a second scan signal output module 122. The first scan signal output module 121 and the second scan signal output module 122 are electrically connected to the gates of data writing transistors M2 in different row pixel circuits 02, respectively. The second type of enable signal output stage includes a first sub-stage and a second sub-stage. The second type of signal output module outputs an enable signal, including:

[0235] Step B21: In the first sub-stage, the first scan signal output module 121 outputs an enable signal.

[0236] Step B22: In the second sub-stage, the second scan signal output module 122 outputs an enable signal.

[0237] The first sub-phase and the second sub-phase are carried out sequentially.

[0238] For example, the first sub-stage and the second sub-stage do not overlap. In this embodiment, the first sub-stage can be... Figure 17 The second stage Z2 in this embodiment can be the second sub-stage. Figure 17 The third stage, Z3.

[0239] In this embodiment of the application, the same shift register unit 10 is set to drive two rows of pixel circuits 02, which can reduce the number of shift register units 10 in the driving circuit 01. While implementing the driving pixel circuit 02, it is beneficial to further reduce the area occupied by the driving circuit 01, thereby further reducing the bezel of the display panel 100.

[0240] like Figure 1 and Figure 4 As shown, this application embodiment also provides a display panel 100, which includes the driving circuit 01 provided in the above embodiment. Exemplarily, the display panel 100 can be any one of an organic light-emitting diode (OLED) display panel, a micro-light-emitting diode (Micro-LED) display panel, or a mini-LED display panel, and this application does not specifically limit it.

[0241] In the display panel 100, the driving circuit 01 can simultaneously drive at least one of the gate reset transistor M1 and the threshold grabbing transistor M3 in the pixel circuit 02, as well as the data writing transistor M2. This reduces the number of peripheral driving circuits required for the pixel circuit 02. It helps to reduce the area occupied by the peripheral driving circuits, thereby facilitating the achievement of a narrow bezel in the display panel 100.

[0242] Furthermore, reducing the number of peripheral driving circuits required for the pixel circuit 02 can also reduce the number of clock signals required for the peripheral driving circuits, which is beneficial for reducing the power consumption of the display panel 100.

[0243] Figure 29 This is a schematic diagram of a display device provided in an embodiment of this application.

[0244] This application embodiment also provides a display device 200, such as... Figure 29 As shown, the display device 200 includes the display panel 100 as provided in the above embodiments. Exemplary examples show that the display device 200 can be an electronic device such as a mobile phone, computer, television, vehicle display, or wearable display, and this application does not impose any specific limitations.

[0245] In the display device 200, by configuring at least one of the gate reset transistor M1 and the threshold grabbing transistor M3 in the pixel circuit 02 to be electrically connected to the same driving circuit 01 as the data writing transistor M2, the number of sets of peripheral driving circuits required for the pixel circuit 02 can be reduced. This helps to reduce the area occupied by the peripheral driving circuits, thereby facilitating the achievement of a narrow bezel in the display panel 100.

[0246] Furthermore, reducing the number of peripheral driving circuits required for the pixel circuit 02 can also reduce the number of clock signals required for the peripheral driving circuits, which is beneficial for reducing the power consumption of the display device 200.

[0247] The above description is merely a preferred embodiment of this application and is not intended to limit this application.
