Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic structural diagram of a light-emitting panel in the prior art, as shown in fig. 1, a display region 0101 of the light-emitting panel 001 includes a plurality of display cells 010, a plurality of scanning signal lines 030, and a plurality of data signal lines 040 arranged in an array, the display cells 010 in the same row share one scanning signal line 030, and the display cells 010 in the same column share one data signal line 040; the non-display area 0102 on the side of the display area 0101 is provided with a shift register circuit 020, the shift register circuit 020 includes a plurality of shift register cells 021 arranged in cascade, the scan output end of each shift register cell 021 is electrically connected to each scan signal line in a one-to-one correspondence manner, in one scan cycle, each shift register cell 021 of the shift register circuit 020 sequentially outputs the enable level of the scan signal to each scan signal line 030, so that when the scan signal line 030 transmits the enable level of the scan signal, a row of display cells 010 corresponding to the scan signal line 030 receives the data signal transmitted by each data signal line 040 in a one-to-one correspondence manner, so as to control each display cell 010 to perform display and light emission.
However, in the light-emitting panel 001 of the prior art, each shift register cell 021 of the shift register circuit 020 can only sequentially provide the enable level of the scan signal to each scan signal line, so that the light-emitting panel 001 has a single scan mode and cannot meet the scan requirements in different display modes; meanwhile, when each shift register cell 021 of the shift register circuit 020 sequentially provides the enable level of the scan signal to each scan signal line, if the time of the enable level of the scan signal received by the same scan signal line is T and the display area 0101 of the light-emitting panel 001 includes N scan signal lines, the scan time of one scan cycle is N x T, and when N is a large value, the scan time of one scan cycle is long, which is not favorable for improving the refresh frequency of the light-emitting panel; in addition, when N is a large value, even when the light-emitting panel emits light, the light-emitting panel may flicker, which affects the light-emitting effect of the light-emitting panel.
To solve the above technical problem, an embodiment of the present invention provides a light emitting panel, including: a display area and a non-display area surrounding the display area; the display area comprises a plurality of sub-display areas and a plurality of scanning signal lines which are arranged in an array; the sub-display area comprises at least one display unit; the display units in the sub-display areas in the same row share the scanning signal line; the non-display area comprises a plurality of shift register circuit groups, and the same shift register circuit group comprises at least one shift register circuit; the shift register units in the shift register circuits of different shift register circuit groups are different in number; the scanning output ends of different shifting register units in the same shifting register circuit group are electrically connected with different scanning signal lines; the scanning output ends of different shifting register units of the same shifting register circuit sequentially output the enabling level of a scanning signal; in the same shift register circuit group, the scan output ends of the shift register units with the same arrangement sequence of different shift register circuits output the time overlapping of the enabling levels of the scan signals.
By adopting the technical scheme, on one hand, a plurality of shift register circuit groups are arranged in the non-display area of the light-emitting panel, the number of shift register units which are arranged in a cascade mode in the shift register circuit of the same shift register circuit group is the same, and the number of shift register units which are arranged in the cascade mode in the shift register circuits of different shift register circuit groups is different, so that the display unit in the display area of the light-emitting panel can adopt the shift register units in different shift register circuit groups for scanning, the scanning requirements of different scanning modes of the light-emitting panel are met, and the display control mode of the light-emitting panel is enriched; on the other hand, because the time of the scan output ends of the shift register units with the same arrangement sequence of different shift register circuits in the same shift register circuit group outputting the enable levels of the scan signals is overlapped, when the shift register circuit group comprises two or more shift register circuits, the enable levels of the scan signals can be provided for two or more scan signal lines at the same time, compared with the condition that the enable levels are provided for all the scan signal lines in sequence in one scan period, the scan time of one scan period can be shortened, the refresh frequency of the light-emitting panel is favorably improved, the picture flicker problem is improved, and the display light-emitting effect of the light-emitting panel can be improved; in addition, the light-emitting panel can also be used as a test panel for testing the compatibility of the shift register circuit, so that the optimal shift register circuit group matched with the light-emitting panel display light-emitting requirement is determined by detecting the working state of the shift register circuit of each shift register circuit group, and the purpose of testing the compatibility of the shift register circuit is realized.
The above is the core idea of the present invention, and the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
Fig. 2 is a schematic structural diagram of a light emitting panel according to an embodiment of the present invention, and as shown in fig. 2, the light emitting panel 100 includes a display area 101 and a non-display area 102 surrounding the display area 101; the display area 101 includes a plurality of sub-display areas 10 and a plurality of scanning signal lines 30 arranged in an array; the sub display area 10 includes at least one display unit 11; the display units 11 in the sub-display regions 10 in the same row share the scanning signal line 30, that is, the display units 11 in the same sub-display region 10 share the scanning signal line 30, and the display units 11 in the sub-display regions 10 in the same row also share the scanning signal line 30.
It is understood that one or more display units 11 may be included in the same sub-display area 10, and the display unit may include one or more sub-pixels, which may be designed according to actual needs, and this is not specifically limited in this embodiment of the present invention. Taking an example in which one display unit represents one sub-pixel and the light-emitting panel is a light-emitting panel that can emit light by itself, the display unit 11 may include a light-emitting element and a pixel circuit for driving the light-emitting element to emit light for display.
For example, fig. 3 is a schematic structural diagram of a sub-display area provided in an embodiment of the present invention, as shown in fig. 3, the same sub-display area 10 includes a plurality of display units 11 arranged in an array, the same display unit 11 includes a light emitting element 111 and a pixel circuit 112, and the pixel circuit 112 includes a driving transistor T01 and a switching transistor T02. In the same display unit 11, the gate of the switching transistor T02 receives the SCAN signal SCAN transmitted from the SCAN signal line 30, the first pole of the switching transistor T02 receives the DATA signal DATA, the second pole of the switching transistor T02 is electrically connected to the gate of the driving transistor T01, the first pole of the driving transistor T01 receives the positive power signal PVDD, the second pole of the driving transistor T01 is electrically connected to the first electrode of the light emitting element 111, and the second electrode of the light emitting element 111 receives the negative power signal; when the gate of the switching transistor T02 receives the enable level of the SCAN signal SCAN, the switching transistor T02 is in a turned-on state, so that the DATA signal DATA is transmitted to the gate of the driving transistor T01 through the turned-on switching transistor T02, so that the driving transistor T01 generates a driving current according to the DATA signal transmitted by the switching transistor T02, the driving current is transmitted to the light emitting element 111 through a path composed of the positive power supply PVDD and the negative power supply PVEE, and the light emitting element 111 emits light according to the driving current. When the display units 11 in the same sub-display area 10 are electrically connected to the same scanning signal line 30, the display units 11 in the same sub-display area 10 can simultaneously receive the enable levels of the scanning signals, so that the display units 11 in the sub-display area 10 can simultaneously receive the corresponding data signals and simultaneously emit light according to the received data signals, which can shorten the total time of providing the enable levels of the scanning signals to the display units 11 in the sub-display area 10 to a certain extent, compared with the case of providing the enable levels of the scanning signals to the display units in different rows, thereby shortening the scanning time of one scanning period of the light-emitting panel. The light emitting element 111 may be an Organic Light Emitting Diode (OLED), a micro-LED, a mini-LED, and the like, which is not specifically limited in this embodiment of the present invention. In an alternative embodiment, the light emitting element 111 is preferably a mini-LED with a smaller size to allow a higher resolution of the light emitting panel.
It should be noted that fig. 3 only exemplarily shows the structure of the display unit in the sub-display area, but the structure of the display unit in the embodiment of the present invention is not limited thereto, and other structures are also possible, for example, the pixel circuit of the display unit may be a structure of 7T1C (seven transistors and one capacitor) or other existing structures of the pixel circuit, which are well known to those skilled in the art, and this is not specifically limited in the embodiment of the present invention. The light-emitting panel may be a display panel directly displaying a corresponding image, or may be a backlight panel for providing backlight for other display modules, which is not specifically limited in the embodiment of the present invention. Meanwhile, the light-emitting panel is not limited to a self-light-emitting panel, and may also be a liquid crystal light-emitting panel or other non-self-light-emitting panels, which is not specifically limited in the embodiments of the present invention.
It can be understood that, in the embodiment of the present invention, the enable level of the scan signal is a signal capable of controlling the corresponding switch transistor in the display unit to be in the on state, and the disable level of the scan signal is a signal capable of controlling the corresponding switch transistor in the display unit to be in the off state; when the switch transistor in the display unit is a P-type transistor, the enable level of the scanning signal is low level, and the disable level of the scanning signal is high level; when the switch transistor in the display unit is an N-type transistor, the enabling level of the scanning signal is high level, and the non-enabling level of the scanning signal is low level; here, the high level refers to a level signal having a relatively high amplitude, and the low level refers to a level signal having a relatively low amplitude, and does not refer to their respective polarities. Meanwhile, the concepts of the enable level and the disable level mentioned in other places of the embodiments of the present invention may refer to the above definitions, and the embodiments of the present invention do not describe this.
For convenience of description, in the embodiments of the present invention, the structure of the display unit shown in fig. 3 is taken as an example, and technical solutions of the embodiments of the present invention are exemplarily described without specific description.
With continued reference to fig. 2, the non-display area 102 of the light-emitting panel 100 includes a plurality of shift register circuit groups 20, and the same shift register circuit group 20 includes at least one shift register circuit; the shift register units in the shift register circuits of different shift register circuit groups 20 are different in number; the scanning output ends of different shifting register units in the same shifting register circuit group are electrically connected with different scanning signal lines; the scanning output ends of different shifting register units of the same shifting register circuit sequentially output the enabling level of a scanning signal; in the same shift register circuit group, the scan output ends of the shift register units with the same arrangement sequence of different shift register circuits output the time overlapping of the enabling levels of the scan signals.
It should be noted that the non-display area 102 of the light emitting panel 100 in the embodiment of the invention includes a plurality of shift register circuit sets 20, that is, the non-display area 102 of the light emitting panel 100 may include two or more shift register circuit sets 20, and the number of the shift register circuit sets 20 disposed in the non-display area 102 of the light emitting panel 100 in the embodiment of the invention is not particularly limited. Similarly, the same shift register circuit group 20 may include at least one shift register circuit, that is, the same shift register circuit group 20 may include one, two or more shift register circuits, which is not limited in this embodiment of the present invention.
Illustratively, taking the example that the shift register circuit group 20 of the light emitting panel includes the first shift register circuit group 210 and the second shift register circuit group 220, the first shift register circuit group 210 includes one shift register circuit 211, the second shift register circuit group 220 includes two shift register circuits 221 and 222, and the number of the shift register units 2101 in the shift register circuit 211 of the first shift register circuit group 210 is different from the number of the shift register units 2201(2202) in the shift register circuits 221(222) of the second shift register circuit group 220. For example, the number of shift register units 2101 in the shift register circuits 211 of the first shift register circuit group 210 may be equivalent to the number of scan signal lines 30, while the number of shift register units 2201(2202) in the shift register circuits 221(222) of the second shift register circuit group 220 may be smaller than the number of scan signal lines; at this time, the scan output ends of the shift register units 2101 of the first shift register circuit group 210 may be electrically connected to the scan signal lines 30 in a one-to-one correspondence manner, so that when the shift register circuit 211 of the first shift register circuit group 210 operates, the shift register units 2101 of the shift register circuit 211 can provide the enable levels of the scan signals to the scan signal lines 30 in a one-to-one correspondence manner; the scan output end of each shift register cell 2201 of the shift register circuits 221 of the second shift register circuit group 220 is electrically connected to a part of the scan signal lines 30 in a one-to-one correspondence, and the scan output end of each shift register cell 2202 of the shift register circuit 222 is electrically connected to another part of the scan signal lines 30 in a one-to-one correspondence, so that when the shift register circuits 221 and 222 of the second shift register circuit group 220 operate, each shift register cell 2201 of the shift register circuit 221 can provide the enable level of the scan signal to the scan signal line 30 electrically connected thereto in a one-to-one correspondence, and at the same time, each shift register cell 2202 of the shift register circuit 222 can provide the enable level of the scan signal to the scan signal line 30 electrically connected thereto in a one-to-one correspondence, and when the ith shift register cell 2201 of the shift register circuit 221 outputs the enable level of the scan signal, the ith shift register cell 2202 of the shift register circuit 222 also outputs the enable level of the scan signal, that is, the shift register units 2201 and 2202 in the same order as the shift register circuits 222 and 221 in the second shift register circuit group 220 have overlapping enable levels of the output scan signals.
For example, fig. 4 is a timing chart of the scan signals output by the first shift register circuit group according to the embodiment of the present invention, and fig. 5 is a timing chart of the scan signals output by the second shift register circuit group according to the embodiment of the present invention. Referring to fig. 2 and 4, taking the example that the shift register circuit 211 of the first shift register circuit group 210 includes 12 shift register units, when the first shift register circuit group 210 operates, each shift register unit 2101 of the shift register circuit 211 sequentially outputs the enable level of the SCAN signal SCAN1-12, so that the display units 11 in each row of the sub-display areas 10 can emit light according to the corresponding data signals. With reference to fig. 2 and 5, taking the same shift register circuit 221 (or 222) of the second shift register circuit group 220 including 6 shift register cells 2201 (or 2202) as an example, each shift register cell 2201 of the shift register circuit 221 sequentially outputs the enable level of the SCAN signal SCAN1-6, each shift register cell 2202 of the shift register circuit 222 sequentially outputs the enable level of the SCAN signal SCAN7-12, and the enable level of the SCAN signal SCAN1 overlaps with the enable level of the SCAN signal SCAN7, the enable level of the SCAN signal SCAN2 overlaps with the enable level of the SCAN signal SCAN8, and … the enable level of the SCAN signal SCAN6 overlaps with the enable level of the SCAN signal SCAN 12. Thus, when the light-emitting panel 100 does not need a higher display refresh frequency, the shift register circuit 211 of the first shift register circuit group 210 can be controlled to be in an operating state, and when the light-emitting panel needs a higher display refresh frequency, the shift register circuits 221 and 222 of the second shift register circuit group 220 can be controlled to be in an operating state, so as to meet different display light-emitting requirements of the light-emitting panel 100; meanwhile, in the second shift register circuit group, the times of the scan output ends of the shift register units 2201 and 2202 in the same arrangement order in the different shift register circuits 221 and 222 are overlapped, so that at the same time, the shift register units 2201 and 2202 in the same arrangement order in the shift register circuits 221 and 222 in the second shift register circuit group 220 can simultaneously output the enable circuits of the scan signals, that is, the enable levels of the scan signals are simultaneously provided to the two scan signal lines 30, so that when the shift register circuits 221 and 222 in the second shift register circuit group 220 work, the scan time can be shorter, thereby being beneficial to improving the refresh frequency of the light-emitting panel 100, improving the problem of image flicker caused by longer scan time, and further improving the display luminous effect of the light-emitting panel 100.
In addition, the light emitting panel 100 can also be used as a test panel for testing compatibility of the shift register circuits, that is, when the first shift register circuit group 210 operates, the display light emitting state of the light emitting panel 100 can be detected to determine compatibility between the shift register circuit 211 in the first shift register circuit group 210 and the light emitting panel 100, and when the second shift register circuit group 220 operates, the display light emitting state of the light emitting panel 100 can be detected to determine compatibility between the shift register circuits 221 and 222 in the second shift register circuit group 220 and the light emitting panel 100, so as to achieve the purpose of testing compatibility between different shift register circuits and the light emitting panel 100.
It should be noted that fig. 2 is a schematic diagram of an embodiment of the present invention, and fig. 2 shows, by way of example only, that different shift register circuit groups (210 and 220) are located on the same side of the display area 101; in the embodiment of the invention, different sets of shift register circuits can be distributed on two opposite sides of the display area.
For example, fig. 6 is a schematic structural diagram of another light-emitting panel according to an embodiment of the present invention, when the shift register circuit sets in the light-emitting panel 100 include the first shift register circuit set 210 and the second shift register circuit set 220, the first shift register circuit set 210 and the second shift register circuit set 220 may be respectively located in the non-display areas 102 on two opposite sides of the display area 101, so that the sizes of the non-display areas on two sides of the display area 101 of the light-emitting panel 100 are equivalent, which is beneficial to improving the aesthetic property of the light-emitting panel 100.
For convenience of description, the following description will exemplarily describe the technical solutions of the embodiments of the present invention by taking the case that the shift register circuits are distributed on two sides of the display area as an example.
It is to be understood that fig. 6 exemplarily shows that the first shift register circuit group 210 includes one shift register circuit 211, and the second shift register circuit group 220 includes two shift register circuits 221 and 222; in the embodiment of the present invention, the same shift register circuit group may include one, two, or more shift register circuits, as long as the requirement for different numbers of shift register units in different shift register circuit groups is met, and the number of shift register circuits in each shift register circuit group is not specifically limited in the embodiment of the present invention.
In an alternative embodiment, as shown in fig. 7, each of the first shift register circuit group 210 and the second shift register circuit group 220 may include only one shift register circuit, that is, the first shift register circuit group 210 includes the shift register circuit 211, and the second shift register circuit group 220 includes the shift register circuit 221.
Optionally, with continued reference to fig. 6, each shift register unit 2101 (or 2201 and 2202) in the same shift register circuit group 210 (or 220) is electrically connected to each scan signal line 30 in a one-to-one correspondence, that is, different scan signal lines 30 are electrically connected to the scan output terminals of different shift register units 2101 (or 2201 and 2202) in the same shift register circuit group 210 (or 220), on the premise that the load quantity electrically connected with the scanning output end of each shift register unit 2101 (or 2201 and 2202) is kept consistent, the load quantity electrically connected with the scanning output end of each shift register unit 2101 (or 2201 and 2202) is reduced as much as possible, therefore, when the scanning signal outputted from each shift register unit 2101 (or 2201 and 2202) is transmitted to the display unit 11 of each sub-display section 10, it is possible to have high accuracy, each display unit 11 is allowed to accurately perform display light emission, thereby improving the accuracy of display light emission of the light emitting panel.
In an optional embodiment, the same shift register unit may further electrically connect two or more scan signal lines. Illustratively, as shown in fig. 7, the shift register unit 2201 in the second shift register circuit group 220 is electrically connected to two scan signal lines to provide scan signals for the two scan signal lines at the same time.
It is understood that, with continued reference to fig. 6, the shift register units 2101(2201 or 2202) in the same shift register circuit 211(221 or 222) are arranged in cascade, and the shift register units (2101, 2201, 2202) of different shift register circuits (211, 221, 222) are not connected to each other; in the same shift register circuit 211(221 or 222), the signal input terminals of other shift register units except the first shift register unit are electrically connected to the scan output terminal of the previous shift register unit, that is, in the same shift register circuit, the signal input terminal of the second shift register unit is electrically connected to the scan output terminal of the first shift register unit, the signal input terminal of the third shift register unit is electrically connected to the scan output terminal of the second shift register unit, and so on, the signal input terminal of the last shift register unit is electrically connected to the scan output terminal of the last shift register unit, so that the enable levels of the scan signals output by the shift register units of the same shift register circuit can be sequentially shifted.
Correspondingly, the signal input end of the first-stage shift register unit of each shift register circuit is connected with a starting signal; in the same shift register circuit group, the signal input ends of the first-stage shift register units of different shift register circuits receive the same starting signal; the signal input ends of the first-stage shift register units of different shift register circuit groups receive different starting signals; therefore, the shift register circuits of the same shift circuit group can work simultaneously, and the shift register circuits of different shift register circuit groups do not work simultaneously.
It should be noted that, the shift register circuits in the shift register circuit groups are exemplarily described above only by taking the example that the shift register circuits in each shift register circuit group can only realize unidirectional scanning (the enable level of the scan signal is sequentially output by each shift register unit from the first-stage shift register unit to the last-stage shift register unit), and the cascade connection manner of the shift register units in each shift register circuit group is also exemplarily described, in the embodiment of the present invention, the shift register circuits in each shift register circuit group can also realize the function of bidirectional scanning, that is, the shift register circuits include a forward scanning process (the enable level of the scan signal is sequentially output by each shift register unit from the first-stage shift register unit to the last-stage shift register unit) and a backward scanning process (the enable level of the scan signal is sequentially output by each shift register unit from the last-stage shift register unit to the first-stage shift register unit), in this case, each shift register unit includes two signal input terminals (i.e., a forward scan signal input terminal and a reverse scan signal input terminal); in the same shift register circuit, except that a forward scanning signal input end of a first shift register unit and a reverse scanning signal input end of a last shift register unit respectively receive starting signals, each shift register unit from the first shift register unit to the last shift register unit is electrically connected with a forward scanning input end of a next shift register unit and a scanning output end of a previous shift register unit, and meanwhile, a reverse scanning input end of the previous shift register unit is electrically connected with a scanning output end of the next shift register unit.
It can be understood that each shift register unit at least includes a signal input end and a scan output end, and on the premise that the shift register circuits in each shift register circuit group can normally operate, the specific structure of each shift register unit is not limited in the embodiments of the present invention.
In an alternative embodiment, fig. 8 is a schematic structural diagram of a shift register unit according to an embodiment of the present invention, as shown in fig. 8, the shift register unit may include 12 transistors (M1-M12) and 3 capacitors (C1, C2, and C3), and a forward scan signal input terminal INF, a reverse scan signal input terminal INB, a forward scan control terminal U2D, a reverse scan control terminal D2U, a forward scan clock terminal RSTF, a reverse scan clock terminal RSTB, an output clock terminal OUT, a first level signal terminal VGH, a second level signal terminal VGL, a scan output terminal Gout, and a clear signal terminal GAS; the gate of the transistor M1 is electrically connected to the forward scan signal input terminal INF, the gate of the transistor M2 is electrically connected to the reverse scan signal input terminal INB, the first pole of the transistor M1 is electrically connected to the forward scan control terminal U2D, the first pole of the transistor M2 is electrically connected to the reverse scan control terminal D2U, and the second poles of the transistors M1 and M2 are electrically connected to the node N11; a gate of the transistor M3 is electrically connected to the forward scan control terminal U2D, a gate of the transistor M4 is electrically connected to the reverse scan control terminal D2U, a first pole of the transistor M3 is electrically connected to the forward scan clock terminal RSTF, a first pole of the transistor M4 is electrically connected to the reverse scan clock terminal RSTB, second poles of the transistors M3 and M4 are electrically connected to the gate of the transistor M5, a first pole of the transistor M5 is electrically connected to the first level signal terminal VGH, and a second pole of the transistor M5 is electrically connected to the second node N2; a gate of the transistor M6 is electrically connected to the node N2, a gate of the transistor M7 is electrically connected to the node N11, a first pole of the transistor M6 is electrically connected to the second level signal terminal VGL, a second pole of the transistor M6 is electrically connected to the node N11, a first pole of the transistor M7 is electrically connected to the second level signal terminal VGL, and a second pole of the transistor M7 is electrically connected to the node N2; a gate of the transistor M8 and a first plate of the capacitor C2 are electrically connected to the node N2, a first pole of the transistor M8 and a second pole of the capacitor C2 are electrically connected to the second level signal terminal VGL, a second pole of the transistor M8, a first plate of the capacitor C1, and a second pole of the transistor M9 are electrically connected to the scan output terminal Gout, a gate of the transistor M9 and a second plate of the capacitor C1 are electrically connected to the node N12, and a first pole of the transistor M9 is electrically connected to the output clock terminal OUT; the gates of the transistors M10 and M11 are electrically connected with the clear signal terminal GAS, the first poles of the transistors M10 and M11 are electrically connected with the second level signal terminal VGL, the second pole of the transistor M10 is electrically connected with the node N12, and the second pole of the transistor M11 is electrically connected with the scan output terminal Gout; the gate of the transistor M12 is electrically connected to the first level signal terminal VGH, and the first and second poles of the transistor M12 are electrically connected to the nodes N11 and N12, respectively.
For example, taking the transistors in fig. 8 as N-type transistors as an example, fig. 9 is a driving timing diagram of a shift register unit corresponding to fig. 8, and referring to fig. 8 and fig. 9, the operation process of the shift register unit in the forward scanning process of the shift register circuit is as follows: in a time period t0, the zero clearing signal GAS of the zero clearing signal terminal GAS controls the transistors M10 and M11 to be in a conducting state, and the scanning output terminal Gout and the node N12 are both kept as low level signals of the first level signal terminal VGL; in the period t1, the positive direction scan signal input terminal INF receives the enable level of the scan signal SCANi-1 outputted from the previous stage shift register unit, so that the transistor M1 is turned on, the positive scan control signal U2d of the positive scan control terminal U2D is transmitted to the node N11 through the transistor M1, and is transmitted to the node N12 from the node N11 through the transistor M12, to charge the capacitor C1, and when the charged capacity of C1 satisfies the conducting condition of the transistor M9, the transistor M9 is turned on, and transmits the output clock signal OUT of the output clock terminal OUT to the scan output terminal Gout, so that the scan signal SCANi output from the scan output terminal Gout is synchronized with the output clock signal OUT of the output clock terminal OUT, meanwhile, the transistor M7 is turned on under the potential control at the stage N11 to transmit the low level signal of the second level signal terminal VGL to the stage N2, so that the transistor M8 is in an off state; at the stage t2, the output clock signal OUT of the output clock terminal OUT is at a high level, so that the scan output terminal Gout outputs an enable level of the scan signal SCANi; at the stage t3, the transistor M3 transmits the high-level forward clock signal RSTF of the forward scan clock terminal RSTF to the gate of the transistor M4, the transistor M4 is turned on, the transistor M4 transmits the high level signal of the first level signal terminal VGH to the node N2, so as to charge the capacitor C2, meanwhile, the transistor M6 is turned on under the control of the potential of the node N2 to transmit the low level signal of the second level signal terminal VGL to the nodes N11, N12, and C1, so that the transistors M7 and M9 are turned off, at this time, m8 is turned on when the amount of power stored in the capacitor C2 satisfies the turn-on condition of the transistor M8, so that the low level signal of the first level signal terminal VGL is transmitted to the scan output terminal Gout, the scan output terminal Gout outputs the disable level of the scan signal SCANi, and correspondingly, the scan output terminal of the next stage of shift register unit outputs the enable level of the scan signal SCANi-1. The corresponding reverse scan process can be performed by combining the signal at the reverse scan signal input terminal INB, the signal at the reverse scan clock terminal RSTB, and the reverse scan control signal at the reverse scan control terminal D2U, which has a similar principle to the forward scan process and is not described herein again.
It should be noted that fig. 8 and 9 only exemplarily show the structure of the shift register unit and the driving process thereof, and the structure of the shift register unit in each shift register circuit group and the driving process thereof according to the embodiment of the present invention are not limited thereto. Meanwhile, in the embodiment of the present invention, the structures of the shift register units in different shift register circuit groups may be the same or different, and this is not specifically limited in the embodiment of the present invention.
Alternatively, with continued reference to fig. 6, different shift register cells 2101(2201 or 2202) of the same shift register circuit 211(221 or 222) are electrically connected to be adjacent to the scan signal line 30 in sequence.
Specifically, since the shift register units 2101(2201 or 2202) of the same shift register circuit 211(221 or 222) are sequentially cascaded, the shift register units 2101(2201 or 2202) of the same shift register circuit 211(221 or 222) can be sequentially adjacent to each other; on this basis, the scan signal lines 30 can be electrically connected to and adjacent to different shift register units 2101(2201 or 2202) of the same shift register circuit 211(221 or 222), so as to simplify the connection mode between the shift register units and the scan signal lines, which is beneficial to simplifying the design of the light emitting panel 100 and reducing the cost of the light emitting panel 100.
In an alternative embodiment, as shown in fig. 10, the scan signal lines 30 electrically connected to the shift register units 2201(2202) of the same shift register circuit 221 (or 222) may not be adjacent to each other, and as long as the accuracy of the scan signals can be ensured, the connection manner between the scan signal lines 30 and the shift register units 2201(2202) of the same shift register circuit 221 (or 222) is not particularly limited in the embodiment of the present invention.
Optionally, when the plurality of shift register circuit groups include a first shift register circuit group and a second shift register circuit group, the first shift register circuit group includes at least one first shift register circuit; the second shift register circuit group comprises at least one second shift register circuit; the number of the shift register units in the first shift register circuit is N times that of the shift register units in the second shift register circuit; wherein N is a positive integer greater than 1. Accordingly, the number of the second shift register circuits may be N times the number of the first shift register circuits.
Specifically, with reference to fig. 6, the first shift register circuit 211 of the first shift register circuit group 210 includes 12 shift register units 2101, the second shift register circuit 221 of the second shift register circuit group 220 includes 6 shift register units 2201, and the second shift register circuit 222 also includes 6 shift register units 2202, so that the number of the shift register units 2101 in the first shift register circuit 210 is 2 times the number of the shift register units 2201 in the second shift register circuit 221, and is also 2 times the number of the shift register units 2202 in the second shift register circuit 222; in this way, the number of the enable levels of the scan signals output by the second shift register circuit group 220 at a time is 2 times the enable level of the scan signals output by the first shift register circuit group 210 at a time. When the enable level of the output scanning signal is changed in multiple, the frequency or the period of the control signal provided to different shift register circuit groups can also be changed in multiple, so that the processing logic of the provided control signal can be simplified, and the structure of the signal processing circuit can be simplified.
Meanwhile, the first shift register circuit group 210 includes a first shift register circuit 211, and the second shift register circuit group 220 includes two second shift register circuit groups 221 and 222, so that the second shift register circuits (221 and 222) in the second shift register circuit group 220 are N times of the shift register circuits (211) in the first shift register circuit group 210, thereby ensuring that the number of scanning signal lines electrically connected to each shift register unit in each shift register circuit is equivalent, that is, ensuring that the load amounts electrically connected to the scanning output ends of each shift register unit are consistent, and ensuring that the scanning signals transmitted to the display units 11 of each sub-display area 10 are consistent, thereby being beneficial to the consistency of the display luminescence of each display unit 11 and improving the uniformity of the display luminescence of the luminescent panel.
It should be noted that N in the embodiment of the present invention may be any positive integer greater than 1, that is, N may be 2, 3, 4, and …, which is not specifically limited in this embodiment of the present invention; meanwhile, fig. 6 shows, by way of example only, that the first shift register circuit group includes one first shift register circuit, and the second shift register circuit group includes two second shift register circuits; in the embodiment of the present invention, the number of shift register circuits in the shift register circuit group is not limited to this.
For example, fig. 11 is a schematic structural diagram of another light-emitting panel according to an embodiment of the present invention, as shown in fig. 11, the first shift register circuit group 210 includes two first shift register circuits 211 and 212, and the same first shift register circuit 211(212) includes 8 shift register units 2101 (2102); the second shift register circuit group 220 includes four second shift register circuits 221 and 222, and the same second shift register circuit 221(222) includes 4 shift register units 2201 (2202); at this time, the advantageous effects of the luminescent panel shown in fig. 6 can be achieved as well, and will not be described in detail here.
In an alternative embodiment, fig. 12 is a schematic structural diagram of another light emitting panel according to an embodiment of the present invention, as shown in fig. 12, the first shift register circuit group 210 includes a first shift register circuit 211, and the first shift register circuit 211 may include a shift register unit 2101, the second shift register circuit group 220 also includes a second shift register circuit 222, and the second shift register circuit 222 includes two shift register units 2201; in this way, when the first shift register circuit group 210 operates, the shift register units 2101 of the first shift register circuit 211 can simultaneously supply scan signals to all the scan signal lines 30; when the second shift register circuit group 220 is operated, the two shift register cells 2210 sequentially output the enable level of the scan signal, and one of the shift register cells 2210 can simultaneously provide the enable level of the scan signal to one part of the scan signal lines 30, while the other shift register cell 2210 can simultaneously provide the enable level of the scan signal to the other part of the scan signal lines 30.
In an alternative embodiment, as shown in fig. 13, when the first shift register circuit group includes one shift register unit and the second shift register circuit group includes two shift register units, the first shift register circuit group 210 can be further multiplexed as the second shift register circuit 220; at this time, two shift register units 201 may be disposed in the non-display area 102, and the two shift register units 201 are electrically connected to different scanning signals, for example, one of the shift register units 201 is electrically connected to the scanning signal line 30 corresponding to the sub-display area 10 in the odd-numbered row, and the other shift register unit 201 is electrically connected to the scanning signal line 30 corresponding to the sub-display area 10 in the even-numbered row; when the first shift register circuit group works, the two shift register units 201 are combined into one shift register unit, and the enable level of the scanning signal is output to each scanning signal line 30; when the second shift circuit group works, the two shift register units 201 can alternately output the enable level of the scan signal.
On the basis of the foregoing embodiment, optionally, on the premise that the plurality of shift register circuit groups include the first shift register circuit group and the second shift register circuit group, the plurality of shift register circuit groups may further include a third shift register circuit group and a fourth shift register circuit group; the third shift register circuit group comprises at least one third shift register circuit, and the fourth shift register circuit group comprises at least one fourth shift register circuit; the number of the shift register units in the second shift register circuit is M times of the number of the shift register units in the third shift register circuit; the number of the shift register units in the third shift register circuit is P times that of the shift register units in the fourth shift register circuit; wherein M and P are both positive integers greater than 1.
By way of example, fig. 14 is a schematic structural view of another light-emitting panel provided by an embodiment of the invention, as shown in fig. 14, the first shift register circuit 2100 includes eight shift register units 2001, the second shift register circuit 2200 includes four shift register units 2002, the third shift register circuit 2300 includes two shift register units 2003, the fourth shift register circuit 2400 includes one shift register unit 2004, thus, the number of shift register units 2001 in the first shift register circuit 2100 is 2 times the number of shift register units 2002 in the second shift register circuit 2200, the number of shift register units 2002 in the second shift register circuit 2200 is 2 times the number of shift register units 2003 in the third shift register unit 2300, and the number of shift register units 2003 in the third shift register unit 2300 is 2 times the number of shift register units 2004 in the fourth shift register circuit 2400; in this case, N ═ M ═ P ═ 2.
It should be noted that N, M, P may be designed according to actual needs in the embodiment of the present invention, N and M may be the same or different, N and P may also be the same or different, and M and P may also be the same or different, which is not specifically limited in the embodiment of the present invention.

Thus, when the third shift register circuit 2300 is operated, one of the third shift register units 2003 may be controlled to provide the enable level of the scan signal to a part of the scan signal lines 30, and then the other third shift register unit 2003 is controlled to provide the enable level of the scan signal to the other scan signal lines 30, so that the two third shift register units 2003 may sequentially output the enable levels of the scan signals; when the fourth shift register circuit 2400 is in operation, the fourth shift register unit 2004 is controlled to output the enable level of the scan signal to all the scan signal lines 30.
It should be noted that fig. 15 only exemplarily shows a connection manner of two third shift register units 2003 in the third shift register circuit 2300 to the scan signal line 30, that is, one of the third shift register units 2003 in the third shift register circuit 2300 may be electrically connected to the scan signal line 30 corresponding to the odd-numbered sub display area 10, and the other third shift register unit 2003 may be electrically connected to the scan signal line 30 corresponding to the even-numbered sub display area 10. In the embodiment of the present invention, the connection manner between the two third shift register units 2003 in the third shift register circuit 2300 and the scan signal line 30 may be other forms, which is not specifically limited in the embodiment of the present invention.
It is understood that fig. 15 exemplarily shows that the third shift register circuit 2300 and the fourth shift register circuit 2400 are separately disposed in the non-display area 102 of the light-emitting panel 100, but the third shift register unit of the third shift register circuit can be further multiplexed as the fourth shift register unit of the fourth shift register circuit in the embodiment of the present invention.

For example, fig. 17 is a driving timing diagram of a third shift register circuit group according to an embodiment of the present invention, and fig. 18 is a driving timing diagram of a fourth shift register circuit group according to an embodiment of the present invention. The first transistor T1 and the second transistor T2, and the switching transistor of the display unit are all N-type transistors as an example.
Referring to fig. 16 and 17 in combination, when the third shift register circuit group 230 operates, during a display period DT of one frame, the first control signal Con1 includes an enable level and an disable level, the second control signal Con2 also includes an enable level and an disable level, while the first control signal Con1 is at the enable level, the second control signal Con2 is at the disable level, so that the first transistor T1 is in a turn-on state, the second transistor T2 is in a turn-off state, the first transistor T1 transmits the enable level of the SCAN signal SCAN31 to each SCAN signal line 30 corresponding to the sub display regions 10 of the odd-numbered rows, while the second control signal Con2 is at the enable level, the first control signal Con1 is at the disable level, so that the second transistor T2 is in a turn-on state, the first transistor T1 is in a turn-off state, and the second transistor T2 transmits the enable level of the SCAN signal SCAN32 to each SCAN signal line 30 corresponding to the sub display regions 10 of the even-numbered rows. The SCAN signals SCAN31 and SCAN32 may be a continuous enable level, or may be alternating signals of an enable level and a non-enable level corresponding to the first control signal Con1 and the second control signal Con2, which is not limited in this embodiment of the present invention.
Referring to fig. 16 and 18, when the fourth shift register circuit group 240 operates, in the frame display period DT, the first control signal Con1 and the second control signal Con2 both have enable levels, so that the first transistor T1 and the second transistor T2 are both in an on state, the first transistor T1 transmits the enable level of the SCAN signal SCAN41 to each SCAN signal line 30 corresponding to the sub-display area 10 in the odd-numbered rows, and the second transistor T2 transmits the enable level of the SCAN signal SCAN42 to each SCAN signal line 30 corresponding to the sub-display area 10 in the even-numbered rows. In the light emitting panel display light emitting device, the first control signal Con1 and the second control signal Con2 may be held at the enable level, or the first control signal Con1 and the second control signal Con2 may be at the enable level only in the writing stage of the display signal and at the disable level in the holding stage, which is not particularly limited in the embodiment of the present invention. Accordingly, the SCAN signals SCAN41 and SCAN42 may be a continuous enable level, or may be signals corresponding to the first control signal Con1 and the second control signal Con2, which is not limited in this embodiment of the invention.
It can be understood that the number of shift register units in the shift register circuit is related to the number of scan signals that can be output by the shift register circuit, and when the number of shift register units in the shift register circuits of different shift register circuit groups is different, the number of scan signals that can be output by the shift register circuits of different shift register circuit groups is different. If each shift register circuit of the same shift register circuit group can provide scanning signals for all scanning signals of the light-emitting panel, the number of scanning signal lines receiving enabling levels of the scanning signals is different when different shift register circuit groups work, so that different shift register circuit groups correspond to different scanning modes.
Optionally, the shift register circuit groups correspond to multiple scan modes; each shift register unit of the shift register circuit in the shift register circuit group sequentially outputs the enabling level of the scanning signal in a scanning mode corresponding to the shift register circuit, and outputs the non-enabling level of the scanning signal in other scanning modes.
Illustratively, fig. 19 is a timing diagram of scanning driving of a light-emitting panel according to an embodiment of the present invention, and referring to fig. 15 and 19 in combination, when the plurality of shift register circuit groups 20 of the light-emitting panel include the first shift register circuit group 210, the second shift register circuit group 220, the third shift register circuit group 230, and the fourth shift register circuit group 240, the scanning modes of the light-emitting panel 220 include a first scanning mode, a second scanning mode, a third scanning mode, and a fourth scanning mode.
In the first SCAN mode (during DT 1), each shift register cell 2001 of the first shift register circuit 2100 in the first shift register circuit group 210 sequentially outputs enable levels of SCAN signals SCAN11, SCAN12, SCAN13, SCAN14, SCAN15, SCAN16, SCAN17, and SCAN18 to be supplied to each SCAN signal line 30, respectively, so that the display cell of each sub-display area 10 can realize display light emission under control of the corresponding SCAN signal, while the shift register cells (2002, 2003, and 2004) of the shift register circuits (2200, 2300, and 2400) in the other shift register circuit groups (220, 230, and 240) output disable levels of SCAN signals (SCAN21, SCAN22, SCAN23, SCAN24, SCAN31, SCAN32, SCAN 41). At this time, the enable levels of the eight scanning signals are provided for each scanning signal line of the light-emitting panel, so that the display light-emitting requirements of all the sub-display areas of the light-emitting panel can be met.
In the second SCAN mode (during DT 2), each shift register cell 2002 of the second shift register circuit 2200 in the second shift register circuit group 220 sequentially outputs the enable levels of the SCAN signals SCAN21, SCAN22, SCAN23, and SCAN24 to be supplied to each SCAN signal line 30, respectively, so that the display cells of each sub-display area 10 can realize display lighting under the control of the corresponding SCAN signal, and at this time, the shift register cells (2001, 2003, and 2004) of the shift register circuits (2100, 2300, and 2400) in the other shift register circuit groups (210, 230, and 240) output the disable levels of the SCAN signals (SCAN11, SCAN12, SCAN13, SCAN14, SCAN15, SCAN16, SCAN17, SCAN18, SCAN31, SCAN32, SCAN 40). At this time, the enabling levels of the four scanning signals are provided for each scanning signal line of the light-emitting panel, so that the display light-emitting requirements of all the sub-display areas of the light-emitting panel can be met.
In the third SCAN mode (during DT 3), each shift register cell 2003 of the third shift register circuit 2300 in the third shift register circuit group 230 sequentially outputs enable levels of SCAN signals SCAN31 and SCAN32 to be respectively supplied to each SCAN signal line 30 so that the display cells of each sub-display area 10 can realize display light emission under control of the corresponding SCAN signal, and at this time, the shift register cells (2001, 2002 and 2004) of the shift register circuits (2100, 2200 and 2400) in the other shift register circuit groups (210, 220 and 240) output non-enable levels of SCAN signals (n 11, SCAN12, SCAN13, SCAN14, SCAN15, SCAN16, SCAN17, SCAN18, SCAN21, SCAN22, SCAN23, SCAN24, SCAN 40). At this time, the enabling levels of the two scanning signals are provided for each scanning signal line of the light-emitting panel, so that the display light-emitting requirements of all the sub-display areas of the light-emitting panel can be met.
In the fourth SCAN mode (during DT 4), the shift register cell 2004 of the fourth shift register circuit 2400 in the fourth shift register circuit group 240 outputs the enable level of the SCAN signal SCAN40 to all the SCAN signal lines 30 so that the display cells of each sub-display area 10 can realize display light emission under the control of the SCAN signal SCAN40, and at this time, the shift register cells (2001, 2002, and 2003) of the shift register circuits (2100, 2200, and 2300) in the other shift register circuit groups (210, 220, and 230) output the disable levels of the SCAN signals (SCAN11, SCAN12, SCAN13, SCAN14, SCAN15, SCAN16, SCAN17, SCAN18, SCAN21, SCAN22, SCAN23, SCAN24, SCAN31, and SCAN 32). At this time, the enabling level of one scanning signal is provided for each scanning signal line of the light-emitting panel, so that the display light-emitting requirements of all the sub-display areas of the light-emitting panel can be met.
In this way, in different scanning modes, the number of the enabling levels of the scanning signals provided for each scanning signal line of the light-emitting panel is different, so that the time lengths of scanning periods for scanning each scanning signal line in the light-emitting panel are different, and the light-emitting panel can realize the scanning requirements of different refreshing frequencies; meanwhile, different shift register circuit groups are controlled to work in different scanning modes, the working performance of each shift register circuit group and the display luminous state of the display unit of each sub-display area in the luminous panel can be detected, so that the shift register circuit group with good compatibility with the luminous panel is determined, and the shift register circuit group can be arranged in the luminous panel in the subsequent production and manufacturing process of the luminous panel.
Optionally, fig. 20 is a schematic structural diagram of another light-emitting panel according to an embodiment of the present invention, and as shown in fig. 20, the light-emitting panel 100 further includes at least one switch circuit 50 corresponding to at least one shift register circuit group 20; the same switching circuit 50 comprises at least one switching unit 501; the input ends of different switch units 501 are electrically connected to the scan output ends of different shift register units in the same shift register circuit group 20; the output end of the switch unit 501 is electrically connected with the scanning signal line 30 electrically connected with the shift register unit corresponding to the switch unit 501; the control terminals of the switching units 501 of the same switching circuit 50 receive the same switching control signal.
Illustratively, taking the light-emitting panel 100 including two shift register circuit groups 20 (i.e. the first shift register circuit group 210 and the second shift register circuit group 220), and including one switch circuit 50, when the same shift register unit in the shift register circuit group 20 is connected to one scan signal line 30, the input end of each switch unit 501 in the switch circuit 50 is electrically connected to each shift register unit 2001 in the first shift register circuit group 210 in a one-to-one correspondence, and the output end of each switch unit 501 is electrically connected to each scan signal line 30 in a one-to-one correspondence, so that when the switch control signal controls each switch unit 501 to be in a conducting state, the scan signal output by each shift register unit 2001 in the first shift register circuit group 210 can be provided to each scan signal line 30; when the switch control signal controls each switch unit 501 to be in the off state, the scan signal output by each shift register unit 2001 in the first shift register circuit group 210 cannot be transmitted to each scan signal line 30, and the scan signal provided by each shift register unit 2002 in the second shift register circuit group 220 can be accurately provided to each scan signal line 30, and even if the scan signal output by each shift register unit 2001 in the first shift register circuit group 210 is different from the scan signal output by each shift register unit 2002 in the second shift register circuit group 220, the accuracy of the scan signal provided by each shift register unit 2002 in the second shift register circuit group 220 to each scan signal line 30 will not be affected. The switching unit 501 may include, but is not limited to, a transistor.
It should be noted that fig. 20 is only an exemplary diagram of the embodiment of the present invention, and fig. 20 only exemplarily shows that the light emitting panel 100 includes one switching circuit, but the number of switching circuits in the light emitting panel may be plural in the embodiment of the present invention, and in an alternative embodiment, the number of switching circuits may be equivalent to the number of shift register circuit groups.
For example, fig. 21 is a schematic structural diagram of another light-emitting panel according to an embodiment of the invention, and as shown in fig. 21, the light-emitting panel 100 includes two switch circuits 50 (i.e., a first switch circuit 51 and a second switch circuit 51), where the first switch circuit 51 corresponds to the first shift register circuit group 210, and the second switch circuit 52 corresponds to the second shift register circuit group 220, that is, an input end of each switch unit 511 in the first switch circuit 51 is electrically connected to a scan output end of each shift register unit 2001 of the first shift register circuit group 210 in a one-to-one correspondence manner, an output end of each switch unit 511 in the first switch circuit 51 is electrically connected to each scan signal line 30 in a one-to-one correspondence manner, an input end of each switch unit 521 in the second switch circuit 52 is electrically connected to a scan output end of each shift register unit 2002 of the second shift register circuit group 220 in a one-to-one correspondence manner, and an output end of each switch unit 521 in the second switch circuit 52 is electrically connected to each scan signal line 30 in a one-to-one correspondence manner . At this time, when the first shift register circuit group 210 operates, the switch units 511 in the first switch circuit group 51 can be controlled to be in the on state, and the switch units 521 in the second switch circuit group 52 can be controlled to be in the off state, so that the scan signals output by the shift register units 2001 in the first shift register circuit group 210 can be accurately provided to the scan signal lines 30, and the scan signals output by the shift register units 2002 in the second shift register circuit group 220 cannot be transmitted to the scan signal lines 30, thereby ensuring the accuracy of the scan signals output by the shift register units 2001 in the first shift register circuit group 210 to the scan signal lines 30; when the second shift register circuit group 220 operates, the switch units 521 in the second switch circuit 52 can be controlled to be in the on state, and the switch units 511 in the first switch circuit 51 can be controlled to be in the off state, so that the scan signals output by the shift register units 2002 in the second shift register circuit group 220 can be accurately provided to the scan signal lines 30, and the scan signals output by the shift register units 2001 in the first shift register circuit group 210 cannot be transmitted to the scan signal lines 30, thereby ensuring the accuracy of the scan signals output by the shift register units 2002 in the second shift register circuit group 220 to the scan signal lines 30.
As such, when the light emitting panel includes a plurality of switching circuits, the control terminals of the switching units of different switching circuits receive different switching control signals; the switch units of different switch circuits are not switched on simultaneously under the control of different switch control signals, so that the accuracy of the scanning signals output to the scanning signal line by each shift register unit in the shift register circuit group corresponding to the switch circuit to which the switched-on switch unit belongs is ensured.
It should be noted that, in fig. 20 and fig. 21, the signal input terminal of the next shift register unit and the input terminal of the open unit corresponding to the previous shift register unit in the same shift register circuit are electrically connected to the scan output terminal of the previous shift register unit, that is, the signal input terminal of the next shift register unit is directly electrically connected to the scan output terminal of the previous shift register unit, but in the embodiment of the present invention, the signal input terminal of the next shift register unit in the same shift register circuit is electrically connected to the scan output terminal of the previous shift register unit through the switch unit, that is, the signal input terminal of the next shift register unit is electrically connected to the output terminal of the open unit corresponding to the previous shift register unit, so as to achieve indirect connection with the previous shift register unit (as shown in fig. 22).
It can be understood that fig. 20 and 21 only exemplarily show that the output ends of the switch units in the same switch circuit are electrically connected to the scan signal lines in a one-to-one correspondence, while in the embodiment of the present invention, the number of the scan signal lines electrically connected to the output end of each switch unit is consistent with the number of the scan signal lines required to be electrically connected to the shift register unit corresponding to the switch unit, that is, when the shift register unit needs to provide scan signals to S scan signal lines, the shift register unit needs to be electrically connected to S scan signal lines, and the output end of the corresponding switch unit corresponding to the shift register unit also needs to be electrically connected to S scan signal lines, where S is a positive integer.
Alternatively, fig. 23 is a schematic diagram of a partial enlarged structure of a light-emitting panel according to an embodiment of the invention, and as shown in fig. 23, the display area further includes a plurality of data signal lines 60; the display units 11 of the same sub-display section 10 share the data signal line 60, and the display units 11 of different sub-display sections 10 are electrically connected to different data signal lines 60. Thus, when the light-emitting panel displays light, the display units 11 in different sub-display areas 10 can receive different display signals transmitted by different data signal lines 60, so that the display units in different sub-display areas 10 can have different display light-emitting luminances, and the light emitted by different display units can be combined into a colorful picture; and the display units 11 in the same sub-display area 10 can receive the same display signal transmitted by the same data signal line 60, so that the display units 11 in the same sub-display area 10 can have the same display light-emitting brightness, and the light-emitting panel has higher display uniformity.
Alternatively, fig. 24 is a schematic diagram of a partial enlarged structure of another light-emitting panel according to an embodiment of the invention, and as shown in fig. 24, the same sub-display area 10 includes one display unit 11; the display unit 11 includes a pixel circuit 112 and a plurality of light emitting elements 111; the pixel circuit 112 is used for driving the plurality of light emitting elements 111 to emit display light. Thus, all the light emitting elements 111 in the sub-display region 10 can be driven by the same pixel circuit 112, and the number of pixel circuits provided in the light emitting panel can be reduced while the sub-display region 10 has sufficient brightness, so that the structure of the light emitting panel can be simplified, which is beneficial to reducing the cost of the light emitting panel; meanwhile, the space saved by the pixel circuit can be used for arranging the light-emitting element so as to further improve the display brightness and the resolution of the light-emitting panel.
The light emitting elements 111 of the same display unit 11 may be connected in series and/or in parallel. When the light emitting elements 111 are current-type driving elements, the light emitting elements 111 can be connected in series to ensure uniformity of current flowing in the light emitting elements 111, so that the light emitting elements 111 can have high uniformity of display light emission.
It should be understood that the various light-emitting panel configurations shown above may be used, possibly in combination with each other. For example, the structures of the light-emitting panels described in the present invention may be present in parallel, or may be combined in different forms, and the present invention is not limited thereto as long as the desired result of the technical solution of the present invention can be achieved.

Therefore, under different scanning modes, the shift register units in different shift register circuit groups are adopted for scanning, so that the scanning requirements of different scanning modes of the light-emitting panel are met, and the display control mode of the light-emitting panel is enriched; meanwhile, when the time of outputting the enabling levels of the scanning signals by the scanning output ends of the shifting register units with the same arrangement sequence of different shifting register circuits in the same shifting register circuit group is overlapped, if the shifting register circuit group comprises two or more shifting register circuits, the enabling levels of the scanning signals can be provided for two or more scanning signal lines at the same time, compared with the condition that the enabling levels are provided for all the scanning signal lines in sequence in one scanning period, the scanning time of one scanning period can be shortened, so that the refreshing frequency of the light-emitting panel is favorably improved, the picture flicker problem is improved, and the display light-emitting effect of the light-emitting panel can be improved; in addition, the light-emitting panel is also used as a test panel for testing the compatibility of the shift register circuit, and the working states of the shift register circuits of different shift register circuit groups are detected in different scanning modes, so that the optimal shift register circuit group matched with the light-emitting panel display light-emitting requirement is determined, and the purpose of testing the compatibility of the shift register circuit is realized.
