[0042] As described in the background technology, with the development of electronic technology, display devices have been widely used in various fields and various electronic products, and have become an indispensable part of people's lives and work, such as televisions, mobile phones, computers, personal digital assistants, etc. In a display device, the display device generally includes a driving circuit, a scanning circuit, a pixel circuit, a fingerprint recognition circuit, etc. The pixel circuit is used to provide a corresponding driving current for the light-emitting element, the fingerprint recognition circuit is used to collect and identify fingerprints, the driving circuit is mainly used to provide a corresponding driving signal for the pixel circuits or fingerprint recognition circuits belonging to the same group, and the scanning circuit is to cascade these driving circuits, thereby providing driving signals to pixel circuits or fingerprint circuits belonging to different groups according to a set timing. The quality of these circuits directly affects the performance of the display device. As an important component of the display device, it is one of the key research directions of those skilled in the art.
[0043] Based on this, the embodiments of the present application provide a driving circuit and driving method, a scanning circuit and scanning method, and a display device, which effectively solve the technical problems existing in the prior art. The driving circuit realizes the phase conversion control from the effective level of the first control clock signal output by the shift register subcircuit to the first level output by the output subcircuit, and realizes the end time control of the first level output by the output subcircuit based on the control of the interval clock signal, thereby achieving the purpose of adjusting the pulse width of the first level output by the output subcircuit of the driving circuit, and achieving the purpose of adjusting the interval of the first level output by the output subcircuit of adjacent driving circuits in the scanning circuit.
[0044] To achieve the above purpose, the technical solutions provided in the embodiments of the present application are as follows, specifically combined with Figures 1 to 18 The technical solutions provided in the embodiments of the present application are described in detail.
[0045] refer to Figure 1, which is a circuit diagram of a driving circuit provided in an embodiment of the present application, wherein the driving circuit 100 provided in an embodiment of the present application includes a shift register subcircuit 110 and an output subcircuit 120. The first control terminal of the shift register subcircuit 110 is connected to the first control clock signal CK1, the second control terminal of the shift register subcircuit 110 is connected to the second control clock signal CK2, the third control terminal of the shift register subcircuit 110 is connected to the third control clock signal CK3, the start control terminal of the shift register subcircuit 110 is connected to the start control signal STV, the first input terminal of the shift register subcircuit 110 is electrically connected to the first level terminal VG1, and the second input terminal of the shift register subcircuit 110 is electrically connected to the second level terminal VG2; the shift register subcircuit 110 is based on the first control clock signal CK1. The first level of the first level end VG1 is output based on the effective level of the second control clock signal CK2, the inactive level of the first control clock signal CK1 is output based on the effective levels of the third control clock signal CK3 and the start control signal STV, and then the effective level of the first control clock signal CK1 is output, the first level and the second level of the second level end VG2 are opposite in phase, and the effective levels of the first control clock signal CK1, the second control clock signal CK2, the third control clock signal CK3 and the interval clock signal XCK are all in phase with the second level. The first control terminal of the output sub-circuit 120 is electrically connected to the output terminal of the shift register sub-circuit 110, and the second control terminal of the output sub-circuit 120 is connected to the interval clock signal XCK. The first input terminal of the output sub-circuit 120 is electrically connected to the first level terminal VG1, and the second input terminal of the output sub-circuit 120 is electrically connected to the second level terminal VG2. The output sub-circuit 120 outputs the first level based on the active level of the first control clock signal CK1 output by the shift register sub-circuit 110, and outputs the second level based on the active level of the interval clock signal XCK. During a driving cycle of the driving circuit 100, the active levels of the second control clock signal CK2, the third control clock signal CK3, the first control clock signal CK1, and the interval clock signal XCK are arranged in chronological order. That is, during a driving cycle of the driving circuit 100, the second control clock signal CK2 is first at an active level, followed by the third control clock signal CK3, and finally the first control clock signal CK1 is at an active level.
[0046] As can be understood, the driver circuit 100 provided in the embodiment of the present application implements phase conversion control from the active level of the first control clock signal CK1 output by the shift register subcircuit 110 to the first level output by the output subcircuit 120, and controls the end time of the first level output by the output subcircuit 120 based on the control of the interval clock signal XCK. Thus, by optimizing the interval clock signal XCK, the pulse width of the first level output by the output subcircuit 120 can be adjusted, and the interval between the outputs of the first level by the output subcircuits 120 of adjacent driver circuits 100 in the scanning circuit can be adjusted. Furthermore, the technical solution provided in the embodiment of the present application improves upon the shift register subcircuit 110. By adding an output subcircuit 120 connected to the output of the shift register subcircuit 110, the relevant functions of the driver circuit 100 can be implemented, thereby reducing the design difficulty of the driver circuit 100. Optionally, the driving circuit 100 provided in the embodiment of the present application can be used to provide a reset control signal (reset) for the fingerprint recognition circuit. Fingerprint recognition requires different exposure times when the finger is recognized and when the finger is not recognized, and the time required to read data is different. Therefore, the driving circuit 100 provided in the embodiment of the present application can realize the function of adjustable pulse width of the first level and the function of adjustable interval of the first level output by adjacent driving circuits, and can provide an adapted driving signal for the fingerprint recognition circuit. The applicable scenarios of the driving circuit 100 are not limited to the fingerprint recognition circuit. In other embodiments, it can also be used to provide relevant driving signals for other circuits. This application does not impose specific restrictions on this.
[0047] During a driving cycle of the driver circuit 100, a preset time gap exists between the active level of the first control clock signal CK1 and the active level of the interval clock signal XCK provided in the embodiment of the present application. Since the output sub-circuit 120 outputs the first level based on the active level of the first control clock signal CK1 output by the shift register sub-circuit 110, and the output sub-circuit 120 also outputs the second level based on the active level of the interval clock signal XCK, the driver circuit 100 controls the phase transition from the active level of the first control clock signal CK1 output by the shift register sub-circuit 110 to the first level output by the output sub-circuit 120, and controls the end time of the first level output by the output sub-circuit 120 based on the control of the interval clock signal XCK. Therefore, by adjusting the time gap between the active level of the first control clock signal CK1 and the active level of the interval clock signal XCK, the duration of the first level output by the output sub-circuit 120 can be adjusted, that is, the pulse width of the first level output by the output sub-circuit 120 can be adjusted.

[0056] refer to Figure 5FIG. 1 is a circuit diagram of another driving circuit according to an embodiment of the present application. The shift register sub-circuit 110 according to the embodiment of the present application further includes a scanning reset module 115, which receives a reset control signal QST and is electrically connected to the first level terminal VG1. The scanning reset module 115 controls the level of the first node N1 to the first level based on the active level of the reset control signal QST. Specifically, the scanning reset module 115 connects the first level terminal VG1 to the first node N1 based on the active level of the reset control signal QST. Optionally, during a driving cycle of the driving circuit 100, the active level of the reset control signal QST precedes the active level of the second control clock signal CK2. This allows the first node N1 to be reset before the circuit reset module 111. This prevents residual signal at the node during subsequent operation of the driving circuit 100, thereby improving the performance of the driving circuit 100. Alternatively, within a driving cycle of the driving circuit 100, the effective level of the reset control signal QST starts earlier than the effective level of the second control clock signal CK2, and the effective level of the reset control signal QST and the effective level of the second control clock signal CK2 partially overlap in time sequence. Similarly, the scanning reset module 115 resets the first node N1 before the circuit reset module 111, thereby avoiding the problem of residual signal at the node when the driving circuit 100 performs subsequent operations, thereby improving the performance of the driving circuit 100. Alternatively, within a driving cycle of the driving circuit 100, the effective level of the reset control signal QST and the effective level of the second control clock signal CK2 overlap in time sequence. This is not specifically limited in this application, and the timing design of the reset control signal QST and the second control clock signal CK2 needs to be carried out according to actual applications.
[0057] It should be noted that when the driving circuit 100 provided in the embodiment of the present application is applied to a scanning circuit, wherein the scanning circuit includes a plurality of cascaded driving circuits 100, the reset control signal QST is set in timing compared to the second control clock signal CK2 corresponding to the first-stage driving circuit 100. That is, in at least one scanning cycle (one scanning cycle is the time for scanning all cascaded driving circuits), the effective level of the reset control signal QST is before the effective level of the second control clock signal CK2 corresponding to the first-stage driving circuit 100; or, the starting moment of the effective level of the reset control signal QST is earlier than the starting moment of the effective level of the second control clock signal CK2 corresponding to the first-stage driving circuit 100, and the effective level of the reset control signal QST and the effective level of the second control clock signal CK2 corresponding to the first-stage driving circuit 100 partially overlap in time sequence; or, the effective level of the reset control signal QST and the effective level of the second control clock signal CK2 corresponding to the first-stage driving circuit 100 overlap in time sequence, thereby enabling the first node N1 of all driving circuits 100 to be reset first in the at least one scanning cycle, thereby avoiding the problem of residual signals at the nodes when the driving circuit 100 performs subsequent work, thereby improving the performance of the driving circuit 100.

Figure 11 The timing shown takes the overlap of the effective level of the reset control signal QST and the effective level of the second control clock signal CK2 in time sequence in a driving cycle as an example. In the scanning reset phase T1', the scanning reset module 115 resets the driving circuit 100 based on the effective level of the reset control signal QST, that is, the scanning reset module 115 controls the level of the first node N1 to be the first level based on the effective level of the reset control signal QST.
[0071] Specific combination Figure 10 The driving circuit 100 and Figure 11 The timing diagram shown in FIG. 1 is used to describe the driving process of the driving circuit 100 provided in the embodiment of the present application in more detail. Figure 11In the illustrated scan reset phase T1′ (which overlaps with the reset phase T1), the reset control signal QST is at an active level, controlling the eleventh transistor M11 to be turned on, and the gate of the twelfth transistor M12 is connected to the second level of the second level terminal VG2 and is in a normally-on state. At this time, the eleventh transistor M11 and the twelfth transistor M12 connect the first level terminal VG1 to the first node N1. Furthermore, the second control clock signal CK2 is at an active level, controlling the first transistor M1 to be turned on, connecting the second level terminal VG2 to the second node N2. The second level of the second node N2 can control the second transistor M2 to be turned on. Since the gate of the third transistor M3 is connected to the second level of the second level terminal VG2 and is in a normally-on state, the second transistor M2 and the third transistor M3 connect the first level terminal VG1 to the first node N1. Simultaneously, the second level of the second node N2 can control the fourth transistor M4 to be turned on, connecting the first level terminal VG1 to the output terminal of the shift register sub-circuit 110. OUTY indicates that the shift register sub-circuit 110 outputs the first level. At this time, the second capacitor C2 is maintained by the storage voltage to control the conduction of the sixteenth transistor M16 and the eighteenth transistor M18. The eighteenth transistor M18 transmits the second level of the second level terminal VG2 to the gate of the nineteenth transistor M19, controls the conduction of the nineteenth transistor M19, and connects the second level terminal VG2 with the output terminal of the output sub-circuit 120. OUTS indicates that the output sub-circuit 120 outputs the second level. In the start-up phase T2, the third control clock signal CK3 and the start-up control signal STV are at the active level, and accordingly control the fifth transistor M5, the sixth transistor M6, and the eighth transistor M8 to be turned on. Since the gate of the ninth transistor M9 is connected to the second level of the second level terminal VG2 and is in the normally-on state, the fifth transistor M5, the sixth transistor M6, and the ninth transistor M9 connect the second level terminal VG2 and the first node N1, and the eighth transistor M8 connects the first level terminal VG1 and the second node N2. The second level of the first node N1 can control the seventh transistor M7 and the tenth transistor M10 to be turned on. The seventh transistor M7 connects the first level terminal VG1 and the second node N2, and the tenth transistor M10 transmits the first control clock signal CK1 to the output terminal of the shift register sub-circuit 110. OUTY indicates that the output of the shift register sub-circuit 110 is the inactive level of the first control clock signal CK1 at this time. At this time, the second capacitor C2 is maintained by the storage voltage to control the conduction of the sixteenth transistor M16 and the eighteenth transistor M18. The eighteenth transistor M18 transmits the second level of the second level terminal VG2 to the gate of the nineteenth transistor M19, controls the conduction of the nineteenth transistor M19, and connects the second level terminal VG2 with the output terminal of the output sub-circuit 120. OUTS indicates that the output sub-circuit 120 outputs the second level.
[0072] During output phase T3, the first control clock signal CK1 is at an active level. At this time, the first capacitor C1 maintains the control of the tenth transistor M10, which transmits the first control clock signal CK1 to the output terminal of the shift register sub-circuit 110. OUTY indicates the active level of the first control clock signal CK1 output by the shift register sub-circuit 110 at this time. The active level is the same as the second level. The active level of the first control clock signal CK1 output by the shift register sub-circuit 110 controls the thirteenth transistor M13, the fourteenth transistor M14, and the fifteenth transistor M15 to conduct. The thirteenth transistor M13 transmits the first level of the first level terminal VG1 to the gate of the nineteenth transistor M19, thereby turning off the nineteenth transistor M19. The fourteenth transistor M14 and the fifteenth transistor M15 connect the first level terminal VG1 to the output terminal of the output sub-circuit 120. OUTS indicates that the output sub-circuit 120 outputs the first level.
[0073] At the end stage T4, the first control clock signal CK1 is at an inactive level. At this time, the first capacitor C1 maintains the control of the tenth transistor M10, which transmits the first control clock signal CK1 to the output terminal of the shift register sub-circuit 110. OUTY indicates that the shift register sub-circuit 110 outputs the inactive level of the first control clock signal CK1. The interval clock signal XCK is at an active level, which controls the seventeenth transistor M17 to be conductive. The seventeenth transistor M17 transmits the second level of the second level terminal VG2 to the gate of the nineteenth transistor M19, controlling the nineteenth transistor M19 to be conductive. The nineteenth transistor M19 connects the second level terminal VG2 to the output terminal of the output sub-circuit 120. OUTS indicates that the output sub-circuit 120 outputs the second level.
[0074] refer to Figure 12FIG. 1 shows another timing diagram provided by an embodiment of the present application. Within a driving cycle of the driving circuit, a preset time interval Ty exists between the active level of the first control clock signal CK1 and the active level of the interval clock signal XCK. During the preset time interval Ty, the shift register sub-circuit 110 outputs an inactive level of the first control clock signal CK1, and the output sub-circuit 120 maintains outputting the first level. Specifically, during the preset time interval Ty, the first control clock signal CK1 is inactive. At this time, the first capacitor C1 maintains control of the tenth transistor M10, which is turned on. The tenth transistor M10 transmits the first control clock signal CK1 to the output terminal of the shift register sub-circuit 110. OUTY indicates that the shift register sub-circuit 110 outputs the inactive level of the first control clock signal CK1 at this time. The second capacitor C2 maintains control of the nineteenth transistor M19, which is turned off, while maintaining the output level of the output sub-circuit 120 in phase with the first level. It can be seen that the driving circuit 100 provided in the embodiment of the present application can realize the phase conversion control from the effective level of the first control clock signal CK1 output by the shift register sub-circuit 110 to the first level output by the output sub-circuit 120, and based on the control of the interval clock signal XCK, the end time control of the first level output by the output sub-circuit 120 is realized, and by optimizing the interval clock signal XCK, the purpose of adjusting the pulse width of the first level output by the output sub-circuit 120 and the purpose of adjusting the interval of the first level output by the output sub-circuit 120 of the adjacent driving circuits 100 in the scanning circuit are realized.
