Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device.

[0036] In the embodiments of the present application, the term "electrically connected" can mean that two components are directly electrically connected, or can mean that two components are electrically connected via one or more other components.
[0037] Various modifications and changes can be made to the present application without departing from the spirit or scope of the present application, which will be apparent to one skilled in the art. Therefore, the present application is intended to cover modifications and variations of the present application that come within the scope of the corresponding claims (claimed technical solutions) and their equivalents. It should be noted that the embodiments provided by the present application can be combined with each other without contradiction, if possible.
[0038] Before describing the technical solutions provided by the embodiments of the present application, in order to facilitate the understanding of the embodiments of the present application, the present application first specifically describes the problems existing in the related art:
[0039] Organic light emitting diode (OLED) display panel has the advantages of self-illumination, fast response, high brightness, thinness and the like, and has gradually become the mainstream in the display field.
[0040] The inventors have found that, as shown in Figure 1 The related art adds an eighth transistor T8 on the basis of the existing 7T1C pixel circuit, controls the eighth transistor T8 to be turned on by controlling the control signal SP* to be at an on level, writes the signal on the DVH signal line to the N2 node, and resets the N2 node periodically, so as to improve the shift or hysteresis phenomenon of the characteristics of the driving transistor T3 after long-term work by adjusting the potential applied to the N2 node.
[0041] However, for a double data line circuit, if a new DVH signal is added, it is not conducive to the pixel layout design.
[0042] In order to solve the above-mentioned problems in the related technologies, the present application provides a display panel and display device, which facilitates pixel arrangement while realizing the periodic reset of the first or second pole of the driving module of the dual data line circuit.
[0043] The display panel provided in the embodiments of this application will be described first below.
[0044] like Figure 2 As shown, the display panel 1000 may include multiple pixel circuit column groups 100, and each pixel circuit column group 100 may include at least two pixel circuit columns. Each pixel circuit column may be arranged in the row direction X, and each pixel circuit column may include multiple pixel circuits 10 arranged in the column direction Y.
[0045] Figure 2 and Figure 3 Taking a pixel circuit group 100 comprising two pixel circuit columns as an example, but not limited to this, the number of pixel circuit columns included in the pixel circuit group 100 can be set according to the actual situation and is not limited here. For example, a pixel circuit group 100 may include three pixel circuit columns, four pixel circuit columns, etc.
[0046] Each pixel circuit column can connect to two signal lines; that is, each pixel circuit column in pixel circuit column group 100 can connect to two signal lines. Each signal line transmits a data signal and a bias signal to the pixel circuits in the pixel circuit column in a 10-minute time division ratio. Furthermore, two pixel circuit columns in pixel circuit column group 100 can be connected to the same first signal terminal (source) and the same second signal terminal (DVH). The first signal terminal (source) can be used to provide the data signal, and the second signal terminal (DVH) can be used to provide the bias signal.
[0047] For example, at a first moment, the data signal of the first signal terminal (source) can be transmitted to the pixel circuit 10 in the pixel circuit column through one of the two signal lines, and the bias signal of the second signal terminal (DVH) can be transmitted to the pixel circuit 10 in the pixel circuit column through the other of the two signal lines. At a second moment, the bias signal of the second signal terminal (DVH) can be transmitted to the pixel circuit 10 in the pixel circuit column through one of the two signal lines, and the data signal of the first signal terminal (source) can be transmitted to the pixel circuit 10 in the pixel circuit column through the other of the two signal lines. The first moment and the second moment are different moments.
[0048] Thus, this application does not require additional signal lines and can periodically reset the first or second pole of the drive module 11, which is beneficial to improving the offset and hysteresis of the characteristics of the drive module 11 after long-term operation, and also beneficial to pixel arrangement design.
[0049] In some alternative embodiments, the display panel 1000 can further include a first gate circuit 200 and a second gate circuit 300, and the at least two pixel circuit columns can include a first pixel circuit column 110 and a second pixel circuit column 120.
[0050] The two signal lines connected to the first pixel circuit column 110 are connected to the first signal end source through the first gate circuit 200, and the two signal lines connected to the first pixel circuit column 110 are connected to the second signal end DVH through the second gate circuit 300.
[0051] That is, the first end of each of the two signal lines connected to the first pixel circuit column 110 can be connected to the first signal end source through the first gate circuit 200 to receive the data signal of the first signal end source. The second end of each of the two signal lines connected to the first pixel circuit column 110 can be connected to the second signal end DVH through the second gate circuit 300 to receive the bias signal of the second signal end DVH.
[0052] The two signal lines connected to the second pixel circuit column 120 are connected to the first signal end source through the first gate circuit 200, and the two signal lines connected to the second pixel circuit column 120 are connected to the second signal end DVH through the second gate circuit 300.
[0053] That is, the first end of each of the two signal lines connected to the second pixel circuit column 120 can be connected to the first signal end source through the first gate circuit 200 to receive the data signal of the first signal end source. The second end of each of the two signal lines connected to the second pixel circuit column 120 can be connected to the second signal end DVH through the second gate circuit 300 to receive the bias signal of the second signal end DVH.
[0054] The first gate circuit 200 can be used to time-divisionally transmit the data signal provided by the first signal end source to the four signal lines of the pixel circuit column group 100. That is, the first gate circuit 200 can be used to time-divisionally transmit the data signal provided by the first signal end source to the two signal lines connected to the first pixel circuit column 110 and the two signal lines connected to the second pixel circuit column 120.
[0055] The second gate circuit 300 can be used to time-divisionally transmit the bias signal provided by the second signal end DVH to the four signal lines of the pixel circuit column group 100. That is, the second gate circuit 300 can be used to time-divisionally transmit the bias signal provided by the second signal end DVH to the two signal lines connected to the first pixel circuit column 110 and the two signal lines connected to the second pixel circuit column 120.
[0056] In the embodiment, the first gating circuit 200 is arranged between the first signal terminal source and the pixel circuit column group 100, and the second gating circuit 300 is arranged between the second signal terminal DVH and the pixel circuit column group 100. The data signal and the bias signal can be transmitted to the pixel circuit 10 in the pixel circuit column group 100 in time by controlling the on-off of the first gating circuit 200 and the second gating circuit 300.
[0057] In some optional embodiments, the two signal lines connected by the first pixel circuit column 110 can include a first signal line data1 and a third signal line data3, and the two signal lines connected by the second pixel circuit column 120 can include a second signal line data2 and a fourth signal line data4.
[0058] The first gating circuit 200 can include a first switching element K1, a second switching element K2, a third switching element K3, and a fourth switching element K4. The first end of the first switching element K1, the first end of the second switching element K2, the first end of the third switching element K3, and the first end of the fourth switching element K4 are connected with the first signal terminal source. The second end of the first switching element K1 is connected with the first signal line data1. The second end of the third switching element K3 is connected with the third signal line data3. The second end of the fourth switching element K4 is connected with the fourth signal line data4. The second end of the second switching element K2 is connected with the second signal line data2.
[0059] For example, the first switching element K1 can include a first transistor M1, the second switching element K2 can include a second transistor M2, the third switching element K3 can include a third transistor M3, and the fourth switching element K4 can include a fourth transistor M4. The first end of the first switching element K1 can be the first pole of the first transistor M1, and the second end of the first switching element K1 can be the second pole of the first transistor M1. The first end of the second switching element K2 can be the first pole of the second transistor M2, and the second end of the second switching element K2 can be the second pole of the second transistor M2. The first end of the third switching element K3 can be the first pole of the third transistor M3, and the second end of the third switching element K3 can be the second pole of the third transistor M3. The first end of the fourth switching element K4 can be the first pole of the fourth transistor M4, and the second end of the fourth switching element K4 can be the second pole of the fourth transistor M4.
[0060] In the present application, the first pole of each transistor can be one of the source or the drain, and the second pole of each transistor can be the other of the source or the drain.
[0061] The second gating circuit 300 includes a fifth switching element K5, a sixth switching element K6, a seventh switching element K7, and an eighth switching element K8. The first terminal of the fifth switching element K5, the first terminal of the sixth switching element K6, the first terminal of the seventh switching element K7, and the first terminal of the eighth switching element K8 are connected to the second signal terminal DVH. The second terminal of the fifth switching element K5 is connected to the first signal line data1. The second terminal of the sixth switching element K6 is connected to the third signal line data3. The second terminal of the seventh switching element K7 is connected to the fourth signal line data4. The second terminal of the eighth switching element K8 is connected to the second signal line data2.
[0062] The fifth switching element K5 can include a fifth transistor M5, the sixth switching element K6 can include a sixth transistor M6, the seventh switching element K7 can include a seventh transistor M7, and the eighth switching element K8 can include an eighth transistor M8. The first terminal of the fifth switching element K5 can be the first electrode of the fifth transistor M5, and the second terminal of the fifth switching element K5 can be the second electrode of the fifth transistor M5. The first terminal of the sixth switching element K6 can be the first electrode of the sixth transistor M6, and the second terminal of the sixth switching element K6 can be the second electrode of the sixth transistor M6. The first terminal of the seventh switching element K7 can be the first electrode of the seventh transistor M7, and the second terminal of the seventh switching element K7 can be the second electrode of the seventh transistor M7. The first terminal of the eighth switching element K8 can be the first electrode of the eighth transistor M8, and the second terminal of the eighth switching element K8 can be the second electrode of the eighth transistor M8.
[0063] The first switching element K1 and the sixth switching element K6 are turned on or turned off under the control of the first control signal line mux1, the second switching element K2 and the seventh switching element K7 are turned on or turned off under the control of the second control signal line mux2, the third switching element K3 and the fifth switching element K5 are turned on or turned off under the control of the third control signal line mux3, and the fourth switching element K4 and the eighth switching element K8 are turned on or turned off under the control of the fourth control signal line mux4.
[0064] The first control signal on the first control signal line mux1, the second control signal on the second control signal line mux2, the third control signal on the third control signal line mux3, and the fourth control signal on the fourth control signal line mux4 are all different.
[0065] In the present embodiment, by providing a plurality of switching elements in the first gating circuit 200 and the second gating circuit 300 respectively, and further by controlling the turn-on or turn-off of each switching element, the on-off of the first gating circuit 200 and / or the second gating circuit 300 can be controlled, and the data signal and the bias signal can be transmitted to the pixel circuit 10 in the pixel circuit column group 100 in time.
[0066] In addition, since the first switch element K1 and the sixth switch element K6 are simultaneously turned on or turned off, the second switch element K2 and the seventh switch element K7 are simultaneously turned on or turned off, the third switch element K3 and the fifth switch element K5 are simultaneously turned on or turned off, and the fourth switch element K4 and the eighth switch element K8 are simultaneously turned on or turned off, the data signal write time and the bias signal write time are equal for the same pixel circuit 10.
[0067] In other optional embodiments, as shown in FIG. 1C, the two signal lines connected to the first pixel circuit column 110 include a first signal line data1 and a third signal line data3, and the two signal lines connected to the second pixel circuit column 120 include a second signal line data2 and a fourth signal line data4. Figure 4
[0068] The first gating circuit 200 includes a first switch element K1, a second switch element K2, a third switch element K3, and a fourth switch element K4. The first end of the first switch element K1, the first end of the second switch element K2, the first end of the third switch element K3, and the first end of the fourth switch element K4 are connected to a first signal end source. The second end of the first switch element K1 is connected to the first signal line data1. The second end of the second switch element K2 is connected to the second signal line data2. The second end of the third switch element K3 is connected to the third signal line data3. The second end of the fourth switch element K4 is connected to the fourth signal line data4.
[0069] The second gating circuit 300 includes a fifth switch element K5, a sixth switch element K6, a seventh switch element K7, and an eighth switch element K8. The first end of the fifth switch element K5, the first end of the sixth switch element K6, the first end of the seventh switch element K7, and the first end of the eighth switch element K8 are connected to a second signal end DVH. The second end of the fifth switch element K5 is connected to the first signal line data1. The second end of the sixth switch element K6 is connected to the third signal line data3. The second end of the seventh switch element K7 is connected to the fourth signal line data4. The second end of the eighth switch element K8 is connected to the second signal line data2.
[0070] The first switch element K1 is turned on or turned off under the control of a first control signal line mux1. The second switch element K2, the sixth switch element K6, and the seventh switch element K7 are turned on or turned off under the control of a second control signal line mux2. The third switch element K3 is turned on or turned off under the control of a third control signal line mux3. The fourth switch element K4, the fifth switch element K5, and the eighth switch element K8 are turned on or turned off under the control of a fourth control signal line mux4.
[0071] In this embodiment, the first switching element K1 is turned on or off under the control of the first control signal line mux1, the second switching element K2, the sixth switching element K6, and the seventh switching element K7 are all turned on or off under the control of the second control signal line mux2, the third switching element K3 is turned on or off under the control of the third control signal line mux3, and the fourth switching element K4, the fifth switching element K5, and the eighth switching element K8 are all turned on or off under the control of the fourth control signal line mux4. This increases the duration of the output data signal, which is beneficial to improving the effect of threshold compensation, improving the uniformity of the display panel 1000, and reducing the afterimage phenomenon. For example, since the first switching element K1 is turned on or off under the control of the first control signal line mux1, and the fifth switching element K5 is turned on or off under the control of the fourth control signal line mux4, for the first signal line data1, when the first control signal on the first control signal line mux1 is at the on level, the data signal is written. When the fourth control signal on the fourth control signal line mux4 is at the on level, the writing of the data signal stops and the writing of the bias signal begins. As a result, the duration of the output data signal is longer than the duration of the output bias signal, which helps to improve the effect of threshold compensation, improve the uniformity of the display panel 1000, and improve the afterimage phenomenon.
[0072] In some optional embodiments, each pixel circuit 10 in the first pixel circuit column 110 can be connected to both the first signal line data1 and the third signal line data3. That is, the first terminal of each pixel circuit 10 in the first pixel circuit column 110 can be connected to the first signal line data1, and the second terminal of each pixel circuit 10 in the first pixel circuit column 110 can be connected to the third signal line data3. In this way, each pixel circuit 10 in the first pixel circuit column 110 can receive the data signal from the first signal terminal source and the bias signal from the second signal terminal DVH.
[0073] For example, for ease of explanation, such as Figure 3 , Figure 4 , Figure 11 and Figure 14 As shown, the first pixel circuit array 110 may include a first red pixel circuit R1, a first blue pixel circuit B1, a second red pixel circuit R2, and a second blue pixel circuit B2. The first red pixel circuit R1, the first blue pixel circuit B1, the second red pixel circuit R2, and the second blue pixel circuit B2 are all connected to the first signal line data1, and all three are connected to the third signal line data3.
[0074] Each pixel circuit 10 in the second pixel circuit column 120 is connected to both the second signal line data2 and the fourth signal line data4. That is, the first terminal of each pixel circuit 10 in the second pixel circuit column 120 can be connected to the second signal line data2, and the second terminal of each pixel circuit 10 in the second pixel circuit column 120 can be connected to the fourth signal line data4. Thus, each pixel circuit 10 in the second pixel circuit column 120 can receive the data signal from the first signal terminal source and the bias signal from the second signal terminal DVH.
[0075] For example, such as Figure 3 As shown, the second pixel circuit array 120 may include a first green pixel circuit G1, a second green pixel circuit G2, a third green pixel circuit G3, and a fourth green pixel circuit G4. The first green pixel circuit G1, the second green pixel circuit G2, the third green pixel circuit G3, and the fourth green pixel circuit G4 may all be connected to the second signal line data2, and the first green pixel circuit G1, the second green pixel circuit G2, the third green pixel circuit G3, and the fourth green pixel circuit G4 may all be connected to the fourth signal line data4.
[0076] In some alternative implementations, such as Figure 5 As shown, the pixel circuit 10 may include a driving module 11, a data writing module 12, and a bias module 13. The data writing module 12 can be used to transmit data signals to the driving module 11, and the bias module 13 can be used to transmit bias signals to the driving module 11.
[0077] The data writing module 12 of the odd-numbered row pixel circuit 10 in the first pixel circuit column 110 can be connected to the first signal line data1, and the bias module 13 of the odd-numbered row pixel circuit 10 in the first pixel circuit column 110 is connected to the third signal line data3.
[0078] The data writing module 12 of the even-numbered row pixel circuit 10 in the first pixel circuit column 110 can be connected to the third signal line data3, and the bias module 13 of the even-numbered row pixel circuit 10 in the first pixel circuit column 110 is connected to the first signal line data1.
[0079] In this embodiment, since the data writing modules 12 of the odd-numbered row pixel circuits 10 and the even-numbered row pixel circuits 10 in the first pixel circuit column 110 are connected to different signal lines, the data signal writing time of each pixel circuit 10 in the first pixel circuit column 110 can be greater than the scanning time of a row pixel circuit 10. This is beneficial to improve the threshold compensation effect of each pixel circuit 10 in the first pixel circuit column 110, improve the uniformity of the display panel 1000, and improve the image retention problem of the display panel 1000.
[0080] Optionally, the data writing module 12 can be electrically connected between one of the two signal lines to which the pixel circuit column is connected and the control end of the driving module 11, and the control end of the data writing module 12 can be electrically connected with the first scanning signal line scan1. The biasing module 13 can be electrically connected between the other of the two signal lines to which the pixel circuit column is connected and the first end of the driving module 11, and the control end of the biasing module 13 can be electrically connected with the second scanning signal line scan2.
[0081] Exemplarily, as shown in Figure 3 For example, still taking the first pixel circuit column 110 including the first red pixel circuit R1, the first blue pixel circuit B1, the second red pixel circuit R2 and the second blue pixel circuit B2 as an example, the data writing module 12 of the first red pixel circuit R1 and the data writing module 12 of the second red pixel circuit R2 can be connected with the first signal line data1, and the biasing module 13 of the first red pixel circuit R1 and the biasing module 13 of the second red pixel circuit R2 can be connected with the third signal line data3. The data writing module 12 of the first blue pixel circuit B1 and the data writing module 12 of the second blue pixel circuit B2 can be connected with the third signal line data3, and the biasing module 13 of the first blue pixel circuit B1 and the biasing module 13 of the second blue pixel circuit B2 can be connected with the first signal line data1.
[0082] Since the data writing module 12 of the first red pixel circuit R1 is connected with the first signal line data1, the data writing module 12 of the first blue pixel circuit B1 is connected with the second signal line data2, and the data writing module 12 of the second red pixel circuit R2 is connected with the first signal line data1, the data signal writing time length of the first red pixel circuit R1 can be greater than the row scanning time length of the first red pixel circuit R1 row, and the first red pixel circuit R1 only needs to stop writing data signal before the data signal writing of the second red pixel circuit R2.
[0083] The data writing module 12 of the odd row pixel circuit 10 in the second pixel circuit column 120 is connected with the second signal line data2, and the biasing module 13 of the odd row pixel circuit 10 in the second pixel circuit column 120 is connected with the fourth signal line data4.
[0084] The data writing module 12 of the even row pixel circuit 10 in the second pixel circuit column 120 is connected with the fourth signal line data4, and the biasing module 13 of the even row pixel circuit 10 in the second pixel circuit column 120 is connected with the second signal line data2.
[0085] In the embodiment, since the data writing module 12 of the odd row pixel circuit 10 in the second pixel circuit column 120 is connected to a different signal line from the data writing module 12 of the even row pixel circuit 10, the data signal writing time length of each pixel circuit 10 in the second pixel circuit column 120 can be greater than the scanning time length of one row of pixel circuits 10, thereby facilitating to improve the threshold compensation effect of each pixel circuit 10 in the second pixel circuit column 120, improve the uniformity of the display panel 1000, and improve the residual image problem of the display panel 1000.
[0086] Exemplarily, as shown in Figure 3 , still taking that the second pixel circuit column 120 includes the first green pixel circuit G1, the second green pixel circuit G2, the third green pixel circuit G3 and the fourth green pixel circuit G4 for example.

The light-emitting control module 17 is connected in series with the light-emitting module 20 between the first power line PVDD and the second power line PVEE, and can be used to control the light-emitting module 20 to enter the light-emitting stage. The storage module 18 can be electrically connected between the first power line PVDD and the control terminal of the drive module 11, and can be used to maintain the potential of the control terminal of the drive module 11. The light emission control module 17 may include a first light emission control module 171 and a second light emission control module 172. The first light emission control module 171 can be electrically connected between the first power line PVDD and the first terminal of the drive module 11, and the second light emission control module 172 can be electrically connected between the second terminal of the drive module 11 and the first terminal of the light emission module 20.

[0130] In the first bias sub-stage c(i+1), the second scan signal on the second scan signal line scan* of the i+1th row is at the on level, and the bias module 13 of the pixel circuit 10 of the i+1th row is turned on. That is, the eleventh transistor M11 in the first blue pixel circuit B1 and the eleventh transistor M11 in the second green pixel circuit G2 are both turned on, and the ninth transistor M9 in the first blue pixel circuit B1 and the ninth transistor M9 in the second green pixel circuit G2 are both written with bias signals.
[0131] And so on.
[0132] For example, i can be 1.
[0133] Figure 7 and Figure 8 The difference is that, Figure 7 The duration of the data writing sub-stage for each row of pixel circuit 10 is equal to the duration of the first bias sub-stage, while Figure 8The duration of the data writing sub-stage of each row of pixel circuits 10 is greater than the duration of the first biasing sub-stage. As a result Figure 8 The duration of the data writing sub-stage of each row of pixel circuits 10 is greater than the duration of the first biasing sub-stage, which is conducive to improving the threshold compensation effect, improving the uniformity of the display panel 1000, and improving the residual image phenomenon.
[0134] In other optional embodiments, as shown in Figure 9 and Figure 10 The display panel 1000 can include multiple rows of pixel circuits 10. In the display time of one frame of picture, the working process of each row of pixel circuits 10 can include a data writing stage. The data writing sub-stage can be after the first biasing sub-stage. The data writing stage can include the data writing sub-stage and the first biasing sub-stage. In the data writing sub-stage, the driving module 11 of the pixel circuit 10 can write a data signal. In the first biasing sub-stage, the driving module 11 of the pixel circuit 10 can write a bias signal. The control signals on the first control signal line mux1, the second control signal line mux2, the third control signal line mux3, and the fourth control signal line mux4 can be in turn at the on level.
[0135] The data writing sub-stage of the jth row of pixel circuits 10 can at least partially overlap with the first biasing sub-stage of the j+2th row of pixel circuits 10. The data writing sub-stage of any two rows of pixel circuits 10 can not overlap. The first biasing sub-stage of any two rows of pixel circuits 10 can not overlap.
[0136] Wherein, j is a positive integer.
[0137] In the embodiment, the data writing sub-stage of the jth row of pixel circuits 10 can at least partially overlap with the first biasing sub-stage of the j+2th row of pixel circuits 10. That is, when the driving module 11 of the jth row of pixel circuits 10 writes a data signal, the driving module 11 of the j+2th row of pixel circuits 10 writes a bias signal. By time-sharing transmission of the data signal and the bias signal to the same pixel circuit 10 through different signal lines, without increasing additional signal lines, the first electrode or the second electrode of the driving module 11 in the pixel circuit 10 can be periodically reset, which is conducive to improving the offset and hysteresis phenomenon of the characteristics of the driving module 11 after long-term work, and is also conducive to pixel arrangement design.
[0138] Figure 9 The difference between Figure 7 and Figure 7 is that Figure 9 the data writing sub-stage of each row of pixel circuits 10 is after the first biasing sub-stage. Figure 9 The corresponding implementation principle is the same as Figure 7The corresponding implementation principle is similar, and will not be described here.
[0139] Figure 10 Different from Figure 8 , the data writing sub-stage of each row of pixel circuits 10 in Figure 8 is before the first biasing sub-stage, while the data writing sub-stage of each row of pixel circuits 10 in Figure 10 is after the first biasing sub-stage. Figure 10 The corresponding implementation principle is similar to Figure 8 , and will not be described here.
[0140] In some optional embodiments, as shown in Figure 11 , the odd-numbered row pixel circuits 10 in the first pixel circuit column 110 can be connected with the first signal line data1, and the even-numbered row pixel circuits 10 in the first pixel circuit column 110 can be connected with the third signal line data3.
[0141] For example, still taking the case that the first pixel circuit column 110 includes the first red pixel circuit R1, the first blue pixel circuit B1, the second red pixel circuit R2 and the second blue pixel circuit B2 as an example. The first red pixel circuit R1 and the second red pixel circuit R2 are both connected with the first signal line data1, and the first blue pixel circuit B1 and the second blue pixel circuit B2 are both connected with the third signal line data3.
[0142] The odd-numbered row pixel circuits 10 in the second pixel circuit column 120 are connected with the second signal line data2, and the even-numbered row pixel circuits 10 in the second pixel circuit column 120 are connected with the fourth signal line data4.
[0143] For example, still taking the case that the second pixel circuit column 120 includes the first green pixel circuit G1, the second green pixel circuit G2, the third green pixel circuit G3 and the fourth green pixel circuit G4 as an example. The first green pixel circuit G1 and the third green pixel circuit G3 are both connected with the second signal line data2, and the second green pixel circuit G2 and the fourth green pixel circuit G4 are both connected with the fourth signal line data4.
[0144] That is, the data signal and the bias signal are transmitted to each pixel circuit 10 of the first pixel circuit column 110 and each pixel circuit 10 of the second pixel circuit column 120 through the same signal line at different times. For example, the data signal and the bias signal are transmitted to the first red pixel circuit R1 through the first signal line data1 at different times.
[0145] In the embodiment, the odd row pixel circuits 10 in the first pixel circuit column 110 are connected with the first signal line data1, the even row pixel circuits 10 in the first pixel circuit column 110 are connected with the third signal line data3, the odd row pixel circuits 10 in the second pixel circuit column 120 are connected with the second signal line data2, and the even row pixel circuits 10 in the second pixel circuit column 120 are connected with the fourth signal line data4. Each signal line can transmit data signals and bias signals to the pixel circuits 10 in the pixel circuit column in time, without increasing additional signal lines, and the first electrode or the second electrode of the driving module 11 can be periodically reset, which is beneficial to improve the offset and hysteresis of the characteristics of the driving module 11 after long-term work, and is also beneficial to the pixel arrangement design.
[0146] In some optional embodiments, as shown in Figure 14 The pixel circuit 10 can include a driving module 11, a data writing module 12 and a bias module 13. The data writing module 12 can be used to transmit data signals to the driving module 11, and the bias module 13 can be used to transmit bias signals to the driving module 11. The data signals and the bias signals can be the same.
[0147] The data writing module 12 and the bias module 13 of the odd row pixel circuit 10 in the first pixel circuit column 110 are connected with the first signal line data1 respectively, and the data writing module 12 and the bias module 13 of the even row pixel circuit 10 in the first pixel circuit column 110 are connected with the third signal line data3 respectively.
[0148] For example, still taking the first pixel circuit column 110 including the first red pixel circuit R1, the first blue pixel circuit B1, the second red pixel circuit R2 and the second blue pixel circuit B2 as an example. The data writing module 12 of the first red pixel circuit R1 and the bias module 13 of the first red pixel circuit R1 can be connected with the first signal line data1 respectively, and the data writing module 12 of the first blue pixel circuit B1 and the bias module 13 of the first blue pixel circuit B1 can be connected with the third signal line data3 respectively.
[0149] The data writing module 12 and the bias module 13 of the odd row pixel circuit 10 in the second pixel circuit column 120 are connected with the second signal line data2 respectively, and the data writing module 12 and the bias module 13 of the even row pixel circuit 10 in the second pixel circuit column 120 are connected with the fourth signal line data4 respectively.
[0150] For example, the second pixel circuit array 120 is still described as including a first green pixel circuit G1, a second green pixel circuit G2, a third green pixel circuit G3, and a fourth green pixel circuit G4. The data writing module 12 and the biasing module 13 of the first green pixel circuit G1 can be connected to the second signal line data2, respectively. The data writing module 12 and the biasing module 13 of the second green pixel circuit G2 can be connected to the fourth signal line data4, respectively.
[0151] In this embodiment, for the same pixel circuit 10, the data writing module 12 and the bias module 13 are both connected to the same signal line, which can reduce the number of signal lines in the same pixel circuit 10; in addition, the data signal and the bias signal are the same, which can avoid the signal crosstalk problem caused by the difference between the data signal and the bias signal.
[0152] Optionally, such as Figure 12 As shown, the display panel 1000 may also include a light-emitting module 20, and the pixel circuit 10 may also include a first reset module 14, a second reset module 15, a threshold compensation module 16, a light-emitting control module, and a storage module 18. Figure 12 The display panel 1000 and Figure 5 and Figure 6 The difference between the display panel 1000 and the previous one is that... Figure 5 and Figure 6 The data writing module 12 and the bias module 13 are respectively connected to different signal lines, while Figure 12 The data writing module 12 and the bias module 13 are connected to the same signal line Data or Data*. Specifically, signal line Data can be connected to the first signal line data1 or the third signal line data3, and signal line Data* can be connected to the second signal line data2 or the fourth signal line data4. Figure 12 The specific circuit structure of the display panel 1000 and Figure 5 and Figure 6 The specific circuit structure is similar, and will not be described in detail here.
[0153] In some alternative implementations, such as Figure 13 and 15As shown, the display panel 1000 can include a plurality of rows of pixel circuits 10, and the working process of each row of pixel circuits 10 can include a data writing stage, the data writing stage can include a data writing sub-stage and a first biasing sub-stage, the data writing sub-stage is before the first biasing sub-stage, in the data writing sub-stage, the driving module 11 of the pixel circuit 10 writes a data signal, and in the first biasing sub-stage, the driving module 11 of the pixel circuit 10 writes a bias signal; the control signals on the first control signal line mux1, the second control signal line mux2, the third control signal line mux3 and the fourth control signal line mux4 are turn on level in turn;
[0154] The data writing sub-stage of the (n+1)th row of pixel circuits 10 can at least partially overlap with the first biasing sub-stage of the nth row of pixel circuits 10, the data writing sub-stage of any two rows of pixel circuits 10 can not overlap, and the first biasing sub-stage of any two rows of pixel circuits 10 can not overlap;
[0155] Wherein, n is a positive integer.

[0252] By analogy.
[0253] Exemplarily, k can be 1.
[0254] In other optional embodiments, as shown in Figure 21 and Figure 22 , the display panel 1000 can include multiple rows of pixel circuits 10, and the working process of each row of pixel circuits 10 in the display time of one frame of picture can include a data writing stage, the data writing stage can include a data writing sub-stage and a first bias sub-stage, the data writing sub-stage is after the first bias sub-stage, in the data writing sub-stage, the driving module 11 of the pixel circuit 10 writes a data signal, and in the first bias sub-stage, the driving module 11 of the pixel circuit 10 writes a bias signal; the control signals on the first control signal line mux1, the second control signal line mux2, the third control signal line mux3 and the fourth control signal line mux4 can be in turn at the on level;

[0256] wherein p is a positive integer.
[0257] In the embodiment, the data writing sub-stage of the pth row of pixel circuits 10 can at least partially overlap with the first biasing sub-stage of the (p+1)th row of pixel circuits 10, that is, when the driving module 11 of the pth row of pixel circuits 10 writes a data signal, the driving module 11 of the (p+1)th row of pixel circuits 10 writes a biasing signal, the data signal and the biasing signal are transmitted to the same pixel circuit 10 in time division through the same signal line, without increasing additional signal lines, the first electrode or the second electrode of the driving module 11 in the pixel circuit 10 can be periodically reset, which is beneficial to improve the offset and hysteresis of the characteristics of the driving module 11 after long-term work, and is also beneficial to the pixel arrangement design.
[0258] Figure 21 and the difference between Figure 19 lies in that, Figure 19 the data writing sub-stage of each row of pixel circuits 10 in Figure 20 is before the first biasing sub-stage. Figure 21 The corresponding implementation principle is similar to that of Figure 19 and will not be described here.
[0259] Figure 22 and the difference between Figure 20 lies in that, Figure 20 the data writing sub-stage of each row of pixel circuits 10 in Figure 22 is after the first biasing sub-stage. Figure 22 The corresponding implementation principle is similar to that of Figure 20 and will not be described here.
[0260] In some optional embodiments, as shown in Figure 23 , the working process of each row of pixel circuits 10 can further include a data retention stage, and at least one of the data retention stages can include a second biasing sub-stage, in which the driving module 11 of the pixel circuit 10 can write a biasing signal, and the first signal end source can be in a floating state or used to provide a biasing signal.
[0261] In the embodiment, the working process of each row of pixel circuits 10 can further include a data retention stage, and the data retention stage can at least include a second biasing sub-stage, in which the driving module 11 of the pixel circuit 10 can write a biasing signal, thereby facilitating low-frequency display of the display panel 1000. In addition, when the first signal end source is used to provide a biasing signal, it is beneficial to prevent short circuit of the display panel 1000.
[0262] In order to distinguish the bias sub-stage of different row pixel circuits 10, Figure 23 In the embodiment, the second bias sub-stage e(i) corresponds to the i-th row pixel circuit 10, and the second bias sub-stage e(i+1) corresponds to the i+1-th row pixel circuit 10.
[0263] As an example, in the case that the display panel 1000 includes both the first signal end source and the second signal end DVH, in the data writing stage, the first signal end source can be used to provide the data signal, and the second signal end DVH can be used to provide the bias signal. In the data retention stage, the data signal end can be in a suspended state or used to provide the bias signal.
[0264] As another example, in the case that the first signal end source of the display panel 1000 can be used to provide the data signal and the bias signal in time sharing, in the data retention stage, the first signal end source can provide the data signal and the bias signal in time sharing, and in the data retention stage, the first signal end source can continuously provide the bias signal.
[0265] Figure 23 In the embodiment, the data writing sub-stage of the same row pixel circuit 10 in the data writing stage is before the first bias sub-stage, but this is not limited thereto. In other embodiments, the data writing sub-stage of the same row pixel circuit 10 in the data writing stage can be after the first bias sub-stage.
[0266] In the embodiment, the values of i, j, n, m, k and p can be equal or not equal, which is not limited herein. For example, i=j=n=m=k=p=100, or i=98, j=99, n=100, m=101, k=102, p=103, and the like.
[0267] It should be noted that the signal on the third scan signal line scan2 is not shown in each timing diagram provided by the embodiment, and it can be understood that, for the same row pixel circuit 10, the off period of the emission control signal line emit should cover the on period of the third scan signal line scan2. For example, Figure 7 For example, the on period of the third scan signal line scan2 can be before the on period of the first scan signal line scan1, and for the same row pixel circuit 10, in the data writing sub-stage, the off period of the emission control signal line emit should cover the on period of the first scan signal line scan1, the on period of the second scan signal line scan2 and the on period of the third scan signal line scan2.
[0268] Optionally, asFigure 24 As shown, the display panel 1000 may include a display area AA and a non-display area NA that at least partially surrounds the display area AA. The non-display area NA may include a first non-display area NA1 and a second non-display area NA2 that are opposite each other in the column direction Y, with the first non-display area NA1 and the second non-display area NA2 spaced apart from the display area AA. The first non-display area NA1 may include a bonding area BA, which can be used to bond a driver chip.
[0269] As an example, the first gating circuit 200 and the second gating circuit 300 may be set in the first non-display area NA1.
[0270] As another example, one of the first gating circuit 200 and the second gating circuit 300 may be located in the first non-display area NA1, and the other may be located in the second non-display area NA2. For example, the first gating circuit 200 may be located in the first non-display area NA1, and the second gating circuit 300 may be located in the second non-display area NA2.
[0271] In some alternative implementations, the first signal terminal (source) and the second signal terminal (DVH) can be located at opposite ends of the pixel circuit column. The signal line connected to the second signal terminal (DVH) can be located in the non-display area NA of the display panel 1000, or it can be located in the display area AA of the display panel 1000. Since the signal line connected to the second signal terminal (DVH) is relatively large, it is preferable to place the signal line connected to the second signal terminal (DVH) in the non-display area NA. For example, as... Figure 3 and Figure 4 As shown, the first signal terminal source can be located at the lower end of the pixel circuit column, and the second signal terminal DVH can be located at the upper end of the pixel circuit column. In some other embodiments, the first signal terminal source can also be located at the lower end of the pixel circuit column, and the second signal terminal DVH can also be located at the upper end of the pixel circuit column; this is not limited here.
[0272] In some alternative embodiments, the first signal terminal (source) and the second signal terminal (DVH) may both be located at the same end of the pixel circuit column. The signal line connected to the second signal terminal (DVH) may be located in the non-display area NA of the display panel 1000. For example, as Figure 11 and Figure 14 As shown, the first signal terminal source and the second signal terminal DVH can both be located at the lower end of the pixel circuit column. In some other embodiments, the first signal terminal source and the second signal terminal DVH can both be located at the upper end of the pixel circuit column.
