[0042] In the case of using “including”, “having”, and “comprising” described herein, another component may be added unless a clear limiting term such as “only”, “consisting of”, etc. is used. Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.

[0043] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, these elements should not be limited by these terms.

[0045] Furthermore, in the specification, the phrase “planar distribution schematic diagram” refers to a drawing when a target portion is viewed from above, and the phrase “cross-sectional schematic diagram” refers to a drawing when a section taken by vertically cutting the target portion is viewed from the side.

[0046] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0047] As mentioned in the background technology section, the refresh rate and resolution of the display panel are key indicators for measuring the quality of the display panel. With the continuous improvement of user demand, high refresh rate and high resolution have become the industry trend. With the increase of refresh rate and resolution, the pixel charging time of the display panel will be shortened, which will lead to insufficient pixel charging time, so that each pixel cannot be fully charged, and the display effect cannot be guaranteed at low grayscale, affecting the display effect of the display device, such as the problem of poor display uniformity.

[0048] To solve the above technical problems, please refer to Figure 1 The present application proposes a display panel, characterized in that it includes: a plurality of pixel groups 10, a plurality of data signal lines 20 and a plurality of multiplexing circuits 30.

[0049] Among them, multiple pixel groups 10 are arranged along a first direction, the first direction is the X-axis direction shown in the figure, each pixel group 10 includes N sub-pixel columns PL, each sub-pixel column PL corresponds to M data signal lines 20, and at least some sub-pixels P of the same sub-pixel column PL are connected to different data signal lines 20, N≥2, M≥2.

[0050] The multiplexing circuit 30 includes M multiplexing units 301, and the multiplexing unit 301 includes a signal input terminal, N signal output terminals, and N branch control terminals, and each branch control terminal is used to receive a branch control signal Demux; wherein, the i-th data signal line corresponding to each sub-pixel column PL in the same pixel group 10 is connected to each signal output terminal of the i-th multiplexing unit in the corresponding multiplexing circuit, and the display panel also includes multiple fan-out lines (not shown in the figure), and the signal input terminal of each multiplexing unit 301 is connected to a different fan-out line, so that the signal input terminal of each multiplexing unit 301 receives a different data signal source, 1≤i≤M.

[0051] In this example, see Figure 1 The display panel provided in the present application includes a plurality of pixel groups 10 arranged along a first direction, each pixel group 10 includes a plurality of sub-pixel columns PL, each sub-pixel column PL includes a plurality of sub-pixels P arranged along a second direction, and the second direction is the Y-axis direction shown in the figure. In an example, the luminous colors of the sub-pixels P in a sub-pixel column PL are the same, and the luminous colors of the sub-pixels P in adjacent sub-pixel columns PL are different.

[0052] A multiplexing circuit 30 provides a data signal for each sub-pixel P in a pixel group 10, that is, the number of multiplexing circuits 30 in the display panel of the present application is the same as the number of pixel groups 10. Among them, a multiplexing circuit 30 may include M multiplexing units 301, and the number of multiplexing units 301 in a multiplexing circuit 30 is the same as the number of data signal lines corresponding to a sub-pixel column. A multiplexing unit 301 may have a signal input terminal, N signal output terminals and N branch control terminals, each branch control terminal is used to receive a different branch control signal, and the branch control signals received by the branch control terminals in different multiplexing units 301 may be the same. Under the action of the branch control signal Demux received by each branch control terminal, the signal input terminal transmits the received data signal source to the corresponding signal output terminal, thereby charging the corresponding data signal line. Exemplarily, under the action of the kth branch control signal Demux, the signal input end of each multiplexing unit 301 in the same multiplexing circuit 30 can respectively transmit each data signal to the corresponding signal output end of each multiplexing unit 301, thereby charging each data signal line corresponding to the kth sub-pixel column in the pixel group, thereby realizing the multiplexing unit cooperating with multiple data signal lines to charge multiple sub-pixels in a sub-pixel column, thereby improving the charging time of the sub-pixels, and thereby improving the display effect of the display panel.

[0053] In the application, the pixel group includes at least one sub-pixel unit, the sub-pixel unit includes three sub-pixel columns, each sub-pixel column includes a plurality of light-emitting elements, the light-emitting colors of the light-emitting elements in the same sub-pixel column are the same, and the light-emitting colors of the sub-pixel columns in the sub-pixel unit are different. In an example, see Figure 1A pixel group 10 may include a sub-pixel unit, and the sub-pixel unit includes three sub-pixel columns PL, wherein the luminous colors of the three sub-pixel columns PL may be different, for example, the luminous color of a sub-pixel column PL is red, the luminous color of a sub-pixel column PL is green, and the luminous color of a sub-pixel column PL is blue. Each sub-pixel column PL is respectively connected to two data signal lines 20 (data signal line 20-1 and data signal line 20-2), and the multiplexing circuit 30 includes two multiplexing units 301 (multiplexing unit 301-1 and multiplexing unit 301-2), and the multiplexing unit 301-1 and the multiplexing unit 301-2 respectively include a signal input terminal, three signal output terminals and three branch control terminals, and the signal input terminal of the multiplexing unit 301-1 is used to receive the data signal source-1, and the signal input terminal of the multiplexing unit 301-2 is used to receive the data signal source-2. Under the action of the branch control signal Demux-1 received by the first branch control end, the signal input end of the multiplexing unit 301-1 can transmit the data signal source-1 to the data signal line 20-1 corresponding to the first sub-pixel column in the corresponding pixel group 10, and the signal input end of the multiplexing unit 301-2 can transmit the data signal source-2 to the data signal line 20-2 corresponding to the first sub-pixel column in the corresponding pixel group 10; under the action of the branch control signal Demux-2 received by the second branch control end, the signal input end of the multiplexing unit 301-1 can transmit the data signal source-1 to the data signal line 20-2 corresponding to the first sub-pixel column in the corresponding pixel group 10. The signal input end of the multiplexing unit 301-2 can transmit the data signal source-2 to the data signal line 20-2 corresponding to the second sub-pixel column in the corresponding pixel group 10; under the action of the branch control signal Demux-3 received by the third branch control end, the signal input end of the multiplexing unit 301-1 can transmit the data signal source-1 to the data signal line 20-1 corresponding to the third sub-pixel column in the corresponding pixel group 10, and the signal input end of the multiplexing unit 301-2 can transmit the data signal source-2 to the data signal line 20-2 corresponding to the third sub-pixel column in the corresponding pixel group 10. In this way, the two data signal lines corresponding to each sub-pixel column can charge each sub-pixel P in the sub-pixel column PL at the same time, thereby improving the charging time of the sub-pixel and thus improving the display effect of the display panel.

[0054] The display panel provided by the embodiment of the present application includes multiple pixel groups arranged along a first direction, multiple data signal lines, multiple multiplexing circuits and multiple fan-out lines, wherein each pixel group includes N sub-pixel columns, each multiplexing circuit includes M multiplexing units, and each multiplexing unit includes a signal input terminal, N signal output terminals, and N branch control terminals. In the present application, each sub-pixel column is respectively connected to M data signal lines, at least some sub-pixels in the same sub-pixel column are connected to different data signal lines, and the i-th data signal line corresponding to each sub-pixel column in the same pixel group is connected to each signal output end in the i-th multiplexing unit in the corresponding multiplexing circuit, each branch control end is used to receive different branch control signals, and the signal input end of each multiplexing unit is connected to a different fan-out line, so that the signal input end of each multiplexing unit receives a different data signal, and then under the action of the branch control signal received by the branch control end, each signal input end in the multiplexing circuit is controlled to provide a corresponding data signal to the corresponding signal output end, so as to charge the corresponding data signal line, thereby realizing that the multiplexing unit cooperates with multiple data signal lines to charge multiple sub-pixels in a sub-pixel column, thereby improving the charging time of the sub-pixels and thus improving the display effect of the display panel.

[0055] In an exemplary embodiment, see Figure 2 The display panel further includes a plurality of scanning signal lines 40, each scanning signal line 40 being connected to a sub-pixel row.

[0056] The display panel includes multiple driving stages, each driving stage includes: N charging stages and a scanning stage, and there is no overlap between the charging stages. The overlapping time of the scanning stage and the Nth charging stage is less than or equal to a preset time threshold. In the jth charging stage of the N charging stages, the branch control signal received by the jth branch control terminal in the multiplexing unit is a valid level, 1≤j≤N, and in the scanning stage, the scanning signals received by adjacent M rows of sub-pixels are all valid levels.

[0057] In the application, the scanning signal line 40 is used to provide a scanning control signal Scan to the corresponding sub-pixel row to control the data writing process of the sub-pixel in the corresponding sub-pixel row. Before data writing, each multiplexing unit 301 needs to charge the corresponding data signal line, that is, in the first charging stage, the first branch control terminal in the multiplexing circuit receives the branch control signal as an effective level, and each multiplexing unit 301 charges each data signal line corresponding to the first sub-pixel column in the pixel group; in the second charging stage, the second branch control terminal in the multiplexing circuit receives the branch control signal as an effective level, and each multiplexing unit 301 charges each data signal line corresponding to the second sub-pixel column in the pixel group; ...; in the Nth charging stage, the Nth branch control terminal in the multiplexing circuit receives the branch control signal as an effective level, and each multiplexing unit 301 charges each data signal line corresponding to the Nth sub-pixel column in the pixel group. Finally, in the scanning stage, each data signal line charges the data signal into the corresponding sub-pixel.

[0058] In the present application, the pixel arrangement of the display panel can be a real RGB arrangement, which means that the square pixel is evenly divided into three sub-pixels, which are respectively given red (R), green (G), and blue (B). The three colors of red, green, and blue are independent of each other and cannot be produced by mixing other colors. Almost all other colors in nature can be obtained by combining the three primary colors of red, green, and blue in different proportions, thereby ensuring that each pixel can accurately present the three primary colors of red, green, and blue, so that the display panel can achieve full-color display. The pixel group of the present application may include at least one sub-pixel unit, and a sub-pixel unit refers to a combination of an R sub-pixel column, a G sub-pixel column, and a B sub-pixel column.

[0059] It can be understood that when the charging phase and the scanning phase do not overlap, the data signal is first charged to the corresponding data signal line, and when the scanning phase is turned on, the corresponding sub-pixel is charged by the data signal line, that is, pre-charging. When the charging phase and the scanning phase overlap, the data signal is directly charged into the corresponding sub-pixel, that is, direct charging. When the data signal size is the same, the gate potential of the driving transistor in the sub-pixel using the direct charging method is higher than the gate potential of the driving transistor in the sub-pixel using the pre-charging method.

[0060] Since the present application adopts the real RGB pixel arrangement method, the color of the last sub-pixel column of each pixel group can be made the same, that is, the luminous color of the sub-pixel column corresponding to the last charging stage in each driving stage is the same. Since there is no time overlap between the charging stages in the driving stage of the present application, the overlapping time of the Nth charging stage and the scanning stage is less than or equal to the preset time threshold, it can be ensured that the sizes of data signals written to different sub-pixel columns are different, and at least the sub-pixel columns corresponding to the first N-1 charging stages all adopt a pre-charging method. When the Nth charging stage does not overlap with the scanning stage, the last sub-pixel column of each pixel group corresponding to the Nth charging stage adopts a pre-charging method. When the Nth charging stage overlaps with the scanning stage, it can be ensured that the charging method of sub-pixel columns of the same color is the same, so as to ensure the display uniformity of the display panel.

[0061] In addition, in the present application, the adjacent M rows of sub-pixels in each pixel column are connected to different data signal lines to ensure that different data signals are written to the adjacent M rows of sub-pixels, and then the adjacent M rows of sub-pixels can be controlled to receive synchronized scanning signals, that is, to achieve simultaneous control of the adjacent M rows of sub-pixels, so that the duration of the driving phase of the present application is M 1H, where 1H is the ratio of one frame time of the display panel to the number of rows of all sub-pixel rows in the display panel, that is, 1H is the interval duration of the scanning signal of the pixel circuit in the current sub-pixel row and the scanning signal of the pixel circuit in the next sub-pixel row. By achieving simultaneous control of multiple rows of sub-pixels, the duration of the driving phase can be increased, and then the duration of each charging phase can be increased, the charging time of each sub-pixel can be increased, and the display effect of the display panel can be improved.

[0062] In an exemplary embodiment, see Figure 3 The multiplexing unit 301 also includes N switch transistors T, the first electrodes of each switch transistor T are the signal input terminals, the second electrodes of each switch transistor are the corresponding signal output terminals, and the gates of each switch transistor are the branch control terminals.

[0063] In this embodiment, in a multiplexing circuit 30, the first electrode of the qth switch transistor T in each multiplexing unit 301 is respectively connected to the corresponding fan-out line to receive the data signal; the second electrode of the qth switch transistor T in each multiplexing unit 301 is respectively connected to the data signal line of the qth sub-pixel column in the pixel group, and the gate of the qth switch transistor T in each multiplexing unit 301 is connected to the same branch control terminal. Then, under the action of the branch control terminal receiving the branch control signal Demux, the qth switch transistor T in each multiplexing unit 301 is turned on at the same time to charge the data signal line of the qth sub-pixel column in the pixel group through each signal input terminal and the corresponding signal output terminal. Among them, the switch transistor T can be a P-type transistor or an N-type transistor.

[0064] In an exemplary embodiment, see Figure 4 The pixel group 10 includes a first sub-pixel column PL1, a second sub-pixel column PL2 and a third sub-pixel column PL3, each sub-pixel column PL includes a plurality of light-emitting elements, the light-emitting colors of the light-emitting elements in a sub-pixel column PL are the same, the light-emitting colors of the light-emitting elements included in the first sub-pixel column PL1, the second sub-pixel column PL2 and the third sub-pixel column PL3 are different, exemplarily, the light-emitting color of the light-emitting elements included in the first sub-pixel column PL1 is red, the light-emitting color of the light-emitting elements included in the second sub-pixel column PL2 is green, and the light-emitting color of the light-emitting elements included in the third sub-pixel column PL3 is blue.

[0065] Each sub-pixel column PL is respectively connected to two data signal lines 20: a first data signal line 21 and a second data signal line 22.

[0069] In this example, see Figure 5The display panel of the present application has multiple driving stages, and the driving stages include a first charging stage t1, a second charging stage t2, a third charging stage t3 and a scanning stage t4; wherein the first charging stage t1, the second charging stage t2 and the third charging stage t3 do not overlap, and the overlapping time of the third charging stage t3 and the scanning stage t4 is less than a preset time threshold. In the first charging stage, the first multiplexing unit is used to provide a data signal to the first data signal line of the first sub-pixel column, and the second multiplexing unit is used to provide a data signal to the second data signal line of the first sub-pixel column; in the second charging stage, the first multiplexing unit is used to provide a data signal to the first data signal line of the second sub-pixel column, and the second multiplexing unit is used to provide a data signal to the second data signal line of the second sub-pixel column; in the third charging stage, the first multiplexing unit is used to provide a data signal to the first data signal line of the third sub-pixel column, and the second multiplexing unit is used to provide a data signal to the second data signal line of the third sub-pixel column.

[0070] Please refer to Figure 4 and Figure 5In this example, the duration of the driving phase is 2H. In order to increase the charging time of the sub-pixels in this application, two adjacent rows of sub-pixels are set to be charged simultaneously and receive different data signals. For example, in the first charging phase t1, the gate of the switch transistor T1 and the gate of the switch transistor T4 simultaneously receive the low-level shunt control signal Demux1. Under the action of the shunt control signal Demux1, the switch transistor T1 and the switch transistor T4 are turned on, and then the data signal source1 charges the first data signal line 21a, and the data signal source2 charges the second data signal line 22a; then the first charging phase t1 ends and enters the second charging phase t2, the gate of the switch transistor T2 and the gate of the switch transistor T5 simultaneously receive the low-level shunt control signal Demux2, under the action of the shunt control signal Demux2 Under the condition that the switching transistor T2 and the switching transistor T5 are turned on, the data signal source1 charges the first data signal line 21b, and the data signal source2 charges the second data signal line 22b; then the second charging stage t2 ends and enters the third charging stage t3, the gate of the switching transistor T3 and the gate of the switching transistor T6 simultaneously receive the low-level branch control signal Demux3, under the action of the branch control signal Demux3, the switching transistor T3 and the switching transistor T6 are turned on, and the data signal source1 charges the first data signal line 21c, and the data signal source2 charges the second data signal line 22c. The third charging stage t3 may overlap with the scanning stage t4. In the scanning stage t4, the first data signal line 21a and the second data signal line 22a charge the corresponding sub-pixels in the first sub-pixel column, the first data signal line 21b and the second data signal line 22b charge the corresponding sub-pixels in the second sub-pixel column, and the first data signal line 21c, the second data signal line 22c and the two signal input terminals charge the corresponding sub-pixels in the third sub-pixel column. Since the light emitting colors of the third sub-pixel columns in each pixel group are the same, that is, blue, the present application can ensure that the sub-pixel columns of the same color are charged in the same manner to ensure the uniformity of the display panel.

[0071] At the same time, since the first data signal line and the second data signal line corresponding to two adjacent rows of sub-pixels in the sub-pixel column are charged synchronously and the received data signals are different, the present application can synchronously control the pixel circuits of two adjacent rows. For example, for the first row of sub-pixels and the second row of sub-pixels in the first sub-pixel column, in the first charging stage, the first data signal line 21a corresponding to the first row of sub-pixels in the first sub-pixel column receives the data signal source1, and the second data signal line 22a corresponding to the second row of sub-pixels in the first sub-pixel column receives the data signal source2. Therefore, in the scanning stage, the scanning signal scan1 and the scanning signal scan2 can be controlled to be both low-level valid signals, so that the data signal source1 and the data signal source2 are simultaneously written into the first row of sub-pixels and the second row of sub-pixels in the first sub-pixel column, respectively, and the charging time of the sub-pixels is increased by simultaneously controlling multiple rows of sub-pixels.

[0072] It can be understood that at the same time, the size of the data signal received by the signal input end of the first multiplexing unit may be different from the size of the data signal received by the signal input end of the second multiplexing unit. In addition, in different charging stages, the size of the data signal received by the signal input end of the first multiplexing unit may be different, and the size of the data signal received by the signal input end of the second multiplexing unit may also be different.

Exemplarily, the light-emitting colors of the light-emitting elements included in the fourth sub-pixel column PL4 and the seventh sub-pixel column PL7 are red, the light-emitting colors of the light-emitting elements included in the fifth sub-pixel column PL5 and the eighth sub-pixel column PL8 are green, and the light-emitting colors of the light-emitting elements included in the sixth sub-pixel column PL6 and the ninth sub-pixel column PL9 are blue.

For example, for the first row of sub-pixels, the second row of sub-pixels and the third sub-pixel in the fourth sub-pixel column, in the fourth charging stage, the third data signal line 23a corresponding to the first row of sub-pixels in the fourth sub-pixel column PL4 receives the data signal source3, the fourth data signal line 24a corresponding to the second row of sub-pixels in the fourth sub-pixel column PL4 receives the data signal source4, and the fifth data signal line 25a corresponding to the third row of sub-pixels in the fourth sub-pixel column PL4 receives the data signal source5. Therefore, in the scanning stage, the scanning signal scan1, the scanning signal scan2 and the scanning signal scan3 can be controlled to be valid signals of low level, and the data signal source3, the data signal source4 and the data signal source5 are simultaneously written into the first row of sub-pixels, the second row of sub-pixels and the third row of sub-pixels in the fourth sub-pixel column PL4, so as to increase the charging time of the sub-pixels by simultaneously controlling multiple rows of sub-pixels.
