In the same sub-pixel row, one of the second color sub-pixel and the third color sub-pixel is electrically connected to the first type of signal line, and the other is electrically connected to the second type of signal line.

[0011] In an implementation of the first aspect, the sub-pixel columns include a first category sub-pixel column, a second category sub-pixel column and a third category sub-pixel column, the first category sub-pixel column and the second category sub-pixel column both include second color sub-pixels and third color sub-pixels, the third category sub-pixel column includes first color sub-pixels, and the third category sub-pixel column is located between the first category sub-pixel column and the second category sub-pixel column; wherein the second color sub-pixel in the first category sub-pixel column and the third color sub-pixel in the second category sub-pixel column are located in the same sub-pixel row, and the third color sub-pixel in the first category sub-pixel column and the second color sub-pixel in the second category sub-pixel column are located in the same sub-pixel row.

[0030] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0031] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0032] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0033] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0034] Figure 1 The diagram is a plan view of a display panel in the prior art.

[0035] In the prior art, Figure 1 As shown, the display panel 01' includes multiple sub-pixels 10' and multiple data lines 20', the data lines 20' are electrically connected to the pixel circuits in the sub-pixels 10', the data lines 20' extend along the column direction of the display panel 01', and the multiple data lines 20' are arranged along the row direction of the display panel 01'.

[0036] The plurality of data lines 20' include a first data line 21' and a second data line 22', and the plurality of sub-pixels 10' arranged along the column direction form a sub-pixel column 11'. In the same sub-pixel column 11', the sub-pixels 10' in odd-numbered rows are electrically connected to the first data line 21', and the sub-pixels 10' in even-numbered rows are electrically connected to the second data line 22', and the first data line 21' and the second data line 22' are respectively located on opposite sides of the sub-pixel column 11' to which they are electrically connected.

[0037] for example Figure 1 As shown, the first data line 21 ′ is located at the “left” side of the sub-pixel column 11 ′ to which it is electrically connected, and the second data line 22 ′ is located at the “right” side of the sub-pixel column 11 ′ to which it is electrically connected.

[0038] The inventor of the present application has found through research that in the layout design of the sub-pixel 10', the layout environments on the two opposite sides are usually different, and the loads of the first data line 21' and the second data line 22' on the two opposite sides of the sub-pixel 10' are usually different. The sub-pixels 10' in odd rows are all electrically connected to the first data line 21', and the sub-pixels 10' in even rows are all electrically connected to the second data line 22, which easily leads to a large difference in charging between the sub-pixels 10' in odd rows and the sub-pixels 10' in even rows, and thus easily leads to the problem of horizontal stripes on the display panel 01'.

[0039] In view of this, the inventor of the present application has provided a solution after in-depth research.

[0040] Figure 2 A schematic plan view of a display panel provided in an embodiment of the present application.

[0041] The present application embodiment provides a display panel 01, such as Figure 2 As shown, the display panel 01 includes a plurality of sub-pixels 10 and a plurality of first signal lines 20, and the first signal lines 20 are electrically connected to the sub-pixels 10. The first signal lines 20 extend along a first direction Y, and the plurality of first signal lines 20 are arranged along a second direction X, and the first direction Y intersects the second direction X.

[0042] Optionally, the first direction Y is the column direction of the display panel 01 , and the second direction X is the row direction of the display panel 01 .

[0043] Optionally, the first signal line 20 is a data signal line, and the first signal line 20 is used to write a data signal into a pixel circuit in the sub-pixel 10 .

[0044] The plurality of first signal lines 20 include first-type signal lines 21 and second-type signal lines 22, and the plurality of sub-pixels 10 arranged along the first direction Y form a sub-pixel column 11. In the same sub-pixel column 11, some sub-pixels 10 are electrically connected to the first-type signal lines 21, and some sub-pixels 10 are electrically connected to the second-type signal lines 22, and the first-type signal lines 21 and the second-type signal lines 22 are located on opposite sides of the sub-pixel column 11 to which they are electrically connected.

[0045] For example, Figure 2 As shown, of two adjacent sub-pixels 10 in the same sub-pixel column 11 , one is electrically connected to the first-type signal line 21 , and the other is electrically connected to the second-type signal line 22 .

[0046] Among them, the multiple sub-pixels 10 include first color sub-pixels 101, and the multiple sub-pixels 10 arranged along the second direction X form a sub-pixel row 12. In the same sub-pixel row 12, some of the first color sub-pixels 101 are electrically connected to the first type of signal line 21, and some of the first color sub-pixels 102 are electrically connected to the second type of signal line 22.

[0047] That is, among the sub-pixels 10 located in the same row, some of the sub-pixels 10 are electrically connected to the first type of signal line 21 located on one side of the sub-pixel column 11, and some of the sub-pixels 10 are electrically connected to the second type of signal line 22 located on the other side of the sub-pixel column 11. And among the sub-pixels 10 in the same row, the sub-pixels electrically connected to the first type of signal line 21 and the second type of signal line 22 include sub-pixels of the same color.

[0048] In the embodiment of the present application, among the sub-pixels 10 in the same row, some of the sub-pixels 10 are electrically connected to the first type of signal line 21 located on one side of the sub-pixel column 11, and some of the sub-pixels 10 are electrically connected to the second type of signal line 22 located on the other side of the sub-pixel column 11. That is, in a sub-pixel row 12, there are both sub-pixels 10 connected to the first type of signal line 11 and sub-pixels 10 connected to the second type of signal line 22, which can reduce the charging difference of the sub-pixels 10 in different rows, thereby facilitating the reduction of the brightness difference between different sub-pixel rows 12, improving the horizontal stripe problem of the display panel 01, and improving the display quality.

[0049] In addition, the inventor of the present application further discovered that if in the same sub-pixel row 12, only some sub-pixels 10 are electrically connected to the first type of signal line 21, and some sub-pixels 10 are electrically connected to the second type of signal line 22, although the horizontal stripe problem of the display panel 01 can be improved, the horizontal stripe problem may still exist.

[0050] Combination Figure 3 and Figure 4 As shown, Figure 3 is a schematic plan view of a display panel related to the present application, Figure 4 for Figure 3A schematic diagram of brightness difference between odd and even rows of sub-pixels in a display panel shown in FIG. Figure 3 In the display panel shown, the plurality of sub-pixels 10 include a first color sub-pixel 101, a second color sub-pixel 102, and a third color sub-pixel 103. If the sub-pixels 10 of the same color in the same sub-pixel row 12 are all electrically connected to the first type of signal line 21 or the second type of signal line 22, and the sub-pixels 10 of the same color in the odd and even rows are connected to different types of first signal lines 20. Figure 4 As shown, when the display image is white 255 grayscale (W255), the brightness difference LV between the sub-pixels in the odd rows and the sub-pixels in the even rows is 9.3 nit; when the display image is red 255 grayscale (R255), the brightness difference LV between the sub-pixels in the odd rows and the sub-pixels in the even rows is 0.9 nit; when the display image is green 255 grayscale (G255), the brightness difference LV between the sub-pixels in the odd rows and the sub-pixels in the even rows is 6.9 nit; when the display image is blue 255 grayscale (B255), the brightness difference LV between the sub-pixels in the odd rows and the sub-pixels in the even rows is 0.1 nit.

[0051] It can be seen that in the same sub-pixel row 12, if the sub-pixels 10 of the same color are all connected to the first type of signal line 21 or are all connected to the second type of signal line 22, there may still be obvious brightness differences between different sub-pixel rows 12, and the display panel still has the problem of horizontal stripes.

[0052] Therefore, the embodiment of the present application also arranges that in the same sub-pixel row 12, some of the first color sub-pixels 101 are electrically connected to the first type of signal line 21, and some of the first color sub-pixels 101 are electrically connected to the second type of signal line 22. That is, in one sub-pixel row 12, there are both first color sub-pixels 101 connected to the first type of signal line 11 and first color sub-pixels 101 connected to the second type of signal line 22. This is beneficial to reducing the charging difference of the first color sub-pixels 101 in different rows, thereby helping to further reduce the brightness difference between different sub-pixel rows 12, and improving the horizontal stripe problem of the display panel 01.

[0053] Optionally, the first color sub-pixel 101 is a green sub-pixel.

[0054] Combination Figure 3 and Figure 4 It can be seen that the green sub-pixel has a greater impact on the brightness difference between odd and even rows of the display panel. Therefore, by setting the first color sub-pixel 101 to a green sub-pixel, the brightness difference between different sub-pixel rows 12 can be significantly reduced by reducing the charging difference of the green sub-pixels in different rows, which is conducive to better improving the horizontal stripe problem of the display panel 01.

[0055] Please continue to refer to Figure 2In one embodiment of the present application, in the same sub-pixel row 12 , one of two adjacent first color sub-pixels 101 is electrically connected to the first type signal line 21 , and the other is electrically connected to the second type signal line 22 .

[0056] For example, Figure 2 As shown, in the same sub-pixel row 12, two adjacent first color sub-pixels 101 include a first color sub-pixel 101A and a first color sub-pixel 101B. Taking the first color sub-pixel 101 on the "left" side as the first color sub-pixel 101A and the first color sub-pixel 101 on the "right" side as the first color sub-pixel 101B as an example, in the odd sub-pixel row 12, the first color sub-pixel 101A is electrically connected to the first type of signal line 21, and the first color sub-pixel 101B is electrically connected to the second type of signal line 22; in the even sub-pixel row 12, the first color sub-pixel 101A is electrically connected to the second type of signal line 22, and the first color sub-pixel 101B is electrically connected to the first type of signal line 21.

[0057] Furthermore, in the same sub-pixel row 12 , the first color sub-pixels 101 connected to the first type of signal lines 21 and the first color sub-pixels 101 connected to the second type of signal lines 22 are arranged alternately.

[0058] In the embodiment of the present application, two adjacent first color sub-pixels 101 in the same sub-pixel row 12 are electrically connected to different types of first signal lines 20, respectively. This is beneficial for making the first color sub-pixels 101 with charging differences in the same sub-pixel row 12 distributed more evenly, thereby facilitating improving the brightness uniformity of the first color sub-pixels 101 in the same sub-pixel row 12, and further facilitating improving the brightness uniformity of the display panel.

[0059] In one embodiment of the present application, Figure 2 As shown, the plurality of sub-pixels 10 further include a second color sub-pixel 102 and a third color sub-pixel 103. Exemplarily, the second color sub-pixel 102 is a red sub-pixel, and the third color sub-pixel 103 is a blue sub-pixel.

[0060] In the same sub-pixel row 12 , the second color sub-pixel 102 and the third color sub-pixel 103 are both electrically connected to the first type signal line 21 or the second type signal line 22 .

[0061] That is, a subpixel row 12 may include a second color subpixel 102 and a third color subpixel 103 . In the same subpixel row 12 , the second color subpixel 102 and the third color subpixel 103 are both electrically connected to the first type signal line 21 , or are both electrically connected to the second type signal line 22 .

[0062] For example, Figure 2As shown, in odd sub-pixel rows 12, the second color sub-pixel 102 and the third color sub-pixel 103 are both electrically connected to the first type signal line 21. In even sub-pixel rows 12, the second color sub-pixel 102 and the third color sub-pixel 103 are both electrically connected to the second type signal line 22.

[0063] In the embodiment of the present application, in the same sub-pixel row 12, the second color sub-pixel 102 and the third color sub-pixel 103 are both electrically connected to the first type of signal line 21 or the second type of signal line 22, so the second color sub-pixel 102 and the third color sub-pixel 103 in the same row only need to be electrically connected to the same type of first signal line 20, which is conducive to reducing the process complexity of connecting the second color sub-pixel 102 and the third color sub-pixel 103 to the first signal line 20. While improving the horizontal stripe problem of the display panel 01, it is conducive to reducing the manufacturing cost of the display panel 01.

[0064] Figure 5 A schematic plan view of another display panel provided in an embodiment of the present application.

[0065] In one embodiment of the present application, Figure 5 As shown, the plurality of sub-pixels 10 further include a second color sub-pixel 102 and a third color sub-pixel 103. Exemplarily, the second color sub-pixel 102 is a red sub-pixel, and the third color sub-pixel 103 is a blue sub-pixel.

[0066] In the same sub-pixel row 12 , one of the second color sub-pixel 102 and the third color sub-pixel 103 is electrically connected to the first type signal line 21 , and the other is electrically connected to the second type signal line 22 .

[0067] That is, one sub-pixel row 12 may include a second color sub-pixel 102 and a third color sub-pixel 103 . In the same sub-pixel row 12 , the second color sub-pixel 102 and the third color sub-pixel 103 are electrically connected to different types of first signal lines 20 , respectively.

[0068] Furthermore, in the same sub-pixel row 12, multiple second color sub-pixels 102 can be electrically connected to the same type of first signal line 20, or to different types of first signal lines 20; multiple third color sub-pixels 103 can be electrically connected to the same type of first signal line 20, or to different types of first signal lines 20.

[0069] For example, Figure 5 As shown, in any sub-pixel row 12 , the second color sub-pixels 102 are all electrically connected to the first type of signal lines 21 , and the third color sub-pixels 103 are all electrically connected to the second type of signal lines 22 .

[0070] In the embodiment of the present application, the second color sub-pixel 102 and the third color sub-pixel 103 in the same sub-pixel row 12 are respectively electrically connected to different types of first signal lines 20. Then, in the same sub-pixel row 12, the number of sub-pixels 10 electrically connected to the first type of signal line 21 is made equal to the number of sub-pixels 10 electrically connected to the second type of signal line 22, thereby facilitating further reducing the charging difference of the sub-pixels 10 in different rows, thereby facilitating further reducing the brightness difference between different sub-pixel rows 12, and facilitating further improving the horizontal stripe problem of the display panel 01.

[0071] In one embodiment of the present application, Figure 2 and Figure 5 As shown, the sub-pixel columns 11 include a first sub-pixel column 111, a second sub-pixel column 112, and a third sub-pixel column 113. The first sub-pixel column 111 and the second sub-pixel column 112 both include a second color sub-pixel 102 and a third color sub-pixel 103, and the third sub-pixel column 113 includes a first color sub-pixel 101.

[0072] For example, Figure 2 and Figure 5 As shown, the third sub-pixel column 113 may include only the first color sub-pixel 101, excluding the second color sub-pixel 102 and the third color sub-pixel 103. The first sub-pixel column 111 and the second sub-pixel column 112 both include the second color sub-pixel 102 and the third color sub-pixel 103, excluding the first color sub-pixel 101.

[0073] In the display panel 01 , a first-type sub-pixel column 111 or a second-type sub-pixel column 112 is disposed between two adjacent third-type sub-pixel columns 113 .

[0074] The second color sub-pixel 102 in the first sub-pixel column 111 and the third color sub-pixel 103 in the second sub-pixel column 112 are located in the same sub-pixel row 12. The third color sub-pixel 103 in the first sub-pixel column 111 and the second color sub-pixel 102 in the second sub-pixel column 112 are located in the same sub-pixel row 12.

[0075] Optionally, in the same first-type sub-pixel column 111 and the same second-type sub-pixel column 112, sub-pixels 10 of the same color are electrically connected to the same first signal line 20. That is, the colors of the sub-pixels 10 electrically connected to a first signal line 20 may be the same. Based on this setting, it is beneficial to reduce the number of signal jumps on the same first signal line 20, thereby helping to save power consumption.

[0076] For example, Figure 2As shown, in the first sub-pixel column 111, the second color sub-pixel 102 is electrically connected to the first type signal line 21, and the third color sub-pixel 103 is electrically connected to the second type signal line 22. In the second sub-pixel column 112, the third color sub-pixel 103 is electrically connected to the first type signal line 21, and the second color sub-pixel 102 is electrically connected to the second type signal line 22.

[0077] For example, Figure 5 As shown, in the first sub-pixel column 111 and the second sub-pixel column 112 , the second color sub-pixels 102 are electrically connected to the first signal lines 21 , and the third color sub-pixels 103 are electrically connected to the second signal lines 22 .

[0078] Please continue to refer to Figure 2 and Figure 5 In one embodiment of the present application, in the same first-type sub-pixel column 111 and the same second-type sub-pixel column 112 , the second color sub-pixels 102 and the third color sub-pixels 103 are alternately arranged.

[0079] For example, Figure 2 and Figure 5 As shown, in the same first subpixel column 111, the second color subpixel 102 is located in the odd subpixel row 12, and the third color subpixel 103 is located in the even subpixel row 12. In the same second subpixel column 112, the third color subpixel 103 is located in the odd subpixel row 12, and the second color subpixel 102 is located in the even subpixel row 12.

[0080] In the embodiment of the present application, the second color sub-pixels 102 and the third color sub-pixels 103 in the same sub-pixel column 11 are arranged alternately, which is beneficial for making the distance between the first color sub-pixel 101, the second color sub-pixel 102 and the third color sub-pixel 103 closer, thereby facilitating improving the fineness of the displayed image.

[0081] Figure 6 A schematic plan view of another display panel provided in an embodiment of the present application.

[0082] In one embodiment of the present application, Figure 6 As shown, the plurality of sub-pixels 10 further include second color sub-pixels 102 . In the same sub-pixel row 12 , one of two adjacent second color sub-pixels 102 is electrically connected to the first signal line 21 , and the other is electrically connected to the second signal line 22 .

[0083] For example, Figure 6As shown, in the same sub-pixel row 12, two adjacent second-color sub-pixels 102 include a second-color sub-pixel 102A and a second-color sub-pixel 102B. Taking the second-color sub-pixel 102 on the "left" side as the second-color sub-pixel 102A and the second-color sub-pixel 102 on the "right" side as the second-color sub-pixel 102B as an example, in the odd-numbered sub-pixel rows 12, the second-color sub-pixel 102A is electrically connected to the first-type signal line 21, and the second-color sub-pixel 102B is electrically connected to the second-type signal line 22. In the even-numbered sub-pixel rows 12, the second-color sub-pixel 102A is electrically connected to the second-type signal line 22, and the second-color sub-pixel 102B is electrically connected to the first-type signal line 21.

[0084] Based on this arrangement, in a sub-pixel row 12, some of the second color sub-pixels 102 are electrically connected to the first type of signal line 21, and some of the second color sub-pixels 102 are electrically connected to the second type of signal line 22. That is, in a sub-pixel row 12, there are both second color sub-pixels 102 connected to the first type of signal line 11 and second color sub-pixels 102 connected to the second type of signal line 22, which is conducive to reducing the charging difference of the second color sub-pixels 102 in different rows, thereby further reducing the brightness difference between different sub-pixel rows 12, and further improving the horizontal stripe problem of the display panel 01.

[0085] Moreover, electrically connecting two adjacent second color sub-pixels 102 in the same sub-pixel row 12 to different types of first signal lines 20 respectively is also beneficial for making the second color sub-pixels 102 with charging differences in the same sub-pixel row 12 distributed more evenly, thereby facilitating improving the brightness uniformity of the second color sub-pixels 102 in the same sub-pixel row 12, and further facilitating improving the brightness uniformity of the display panel 01.

[0086] Optionally, in the same sub-pixel row 12 , the second color sub-pixels 102 connected to the first type of signal lines 21 and the second color sub-pixels 102 connected to the second type of signal lines 22 are arranged alternately.

[0087] Optionally, the second color sub-pixel 102 is a red sub-pixel. Figure 3 and Figure 4 It can be seen that the red sub-pixel has a relatively large influence on the brightness difference between odd and even rows of the display panel. Therefore, setting the second color sub-pixel 102 as a red sub-pixel can help to further reduce the brightness difference between different sub-pixel rows 12 by reducing the charging difference of the red sub-pixels in different rows, thereby helping to further improve the horizontal stripe problem of the display panel 01.

[0088] Figure 7 A schematic plan view of another display panel provided in an embodiment of the present application.

[0089] In one embodiment of the present application, Figure 6 and Figure 7 As shown, the plurality of sub-pixels 10 further include a third color sub-pixel 103. In the same sub-pixel row 12, one of two adjacent third color sub-pixels 103 is electrically connected to the first type signal line 21, and the other is electrically connected to the second type signal line 22. Optionally, the third color sub-pixel 103 is a blue sub-pixel.

[0090] For example, Figure 6 As shown, in the same sub-pixel row 12, two adjacent third-color sub-pixels 103 include a third-color sub-pixel 103A and a third-color sub-pixel 103B. Taking the third-color sub-pixel 103 on the "left" side as the third-color sub-pixel 103A and the third-color sub-pixel 103 on the "right" side as the third-color sub-pixel 103B as an example, in the odd-numbered sub-pixel row 12, the third-color sub-pixel 103A is electrically connected to the first-type signal line 21, and the third-color sub-pixel 102B is electrically connected to the second-type signal line 22. In the even-numbered sub-pixel row 12, the third-color sub-pixel 103A is electrically connected to the second-type signal line 22, and the third-color sub-pixel 102B is electrically connected to the first-type signal line 21.

[0091] For example, Figure 7 As shown, in the same sub-pixel row 12, two adjacent third-color sub-pixels 103 include a third-color sub-pixel 103A and a third-color sub-pixel 103B. Taking the third-color sub-pixel 103 on the "left" side as the third-color sub-pixel 103A and the third-color sub-pixel 103 on the "right" side as the third-color sub-pixel 103B as an example, in the odd-numbered sub-pixel row 12 and the even-numbered sub-pixel row 12, the third-color sub-pixel 103A is electrically connected to the second-type signal line 22, and the third-color sub-pixel 102B is electrically connected to the first-type signal line 22.

[0092] Based on this arrangement, in a sub-pixel row 12, some of the third color sub-pixels 103 are electrically connected to the first type of signal line 21, and some of the third color sub-pixels 103 are electrically connected to the second type of signal line 22. That is, in a sub-pixel row 12, there are both third color sub-pixels 103 connected to the first type of signal line 11 and third color sub-pixels 103 connected to the second type of signal line 22, which is conducive to reducing the charging difference of the third color sub-pixels 103 in different rows, thereby further reducing the brightness difference between different sub-pixel rows 12, and further improving the horizontal stripe problem of the display panel 01.

[0093] Moreover, electrically connecting two adjacent third color sub-pixels 103 in the same sub-pixel row 12 to different types of first signal lines 20 respectively is also beneficial for making the third color sub-pixels 103 with charging differences in the same sub-pixel row 12 distributed more evenly, thereby facilitating improving the brightness uniformity of the third color sub-pixels 103 in the same sub-pixel row 12, and further facilitating improving the brightness uniformity of the display panel 01.

[0094] Optionally, in the same sub-pixel row 12 , the third color sub-pixels 103 connected to the first type of signal lines 21 and the third color sub-pixels 103 connected to the second type of signal lines 22 are arranged alternately.

[0095] Figure 8 A schematic plan view of another display panel provided in an embodiment of the present application.

[0096] like Figure 8 As shown, in one embodiment of the present application, the display panel 01 also includes at least one demultiplexer 30, and the demultiplexer 30 may include an input terminal 31 and multiple output terminals 32, and the multiple output terminals 32 are electrically connected to the first signal line 20 respectively, and the input terminal 31 of the demultiplexer 30 is electrically connected to the driving chip (not shown in the figure).

[0097] The demultiplexer 30 includes a plurality of switches K, the first electrodes of the plurality of switches K are electrically connected and electrically connected to the input terminal 31 of the demultiplexer 30, and the second electrodes of the plurality of switches K are electrically connected to the output terminals 32 of the demultiplexer 30 in a one-to-one correspondence. The demultiplexer 30 also includes a plurality of control signal lines MUX, and the control terminals of the switches K are electrically connected to the control signal lines MUX. The driver chip transmits a data signal to the input terminal 31 of the demultiplexer 30, and the signal transmitted by the control signal line MUX controls whether the plurality of output terminals 32 of the demultiplexer 30 output a signal by controlling the switch state of the switches K.

[0098] For example, Figure 8 As shown, the demultiplexer 30 includes an input terminal 31 and four output terminals 32, wherein the four output terminals 32 include a first output terminal 321, a second output terminal 322, a third output terminal 323 and a fourth output terminal 324, wherein the first output terminal 321 and the second output terminal 322 are electrically connected to the first signal line 20 connecting the odd-numbered rows of sub-pixels 10, and the third output terminal 323 and the fourth output terminal 324 are electrically connected to the first signal line 20 connecting the even-numbered rows of sub-pixels 10.

[0099] The multiple switches K include a first switch K1, a second switch K2, a third switch K3 and a fourth switch K4. The first poles of the first switch K1, the second switch K2, the third switch K3 and the fourth switch K4 are electrically connected and electrically connected to the input terminal 31 of the demultiplexer 30. The second poles of the first switch K1 and the second switch K2 are electrically connected to the first output terminal 321 and the second output terminal 322 respectively. The second poles of the third switch K3 and the fourth switch K4 are electrically connected to the third output terminal 323 and the fourth output terminal 324 respectively.

[0100] The multiple control signal lines MUX include a first control signal line MUX1, a second control signal line MUX2, a third control signal line MUX3 and a fourth control signal line MUX4. The first control signal line MUX1 is electrically connected to the control end of the first switch K1, the second control signal line MUX2 is electrically connected to the control end of the second switch K2, the third control signal line MUX3 is electrically connected to the control end of the third switch K3, and the fourth control signal line MUX4 is electrically connected to the control end of the fourth switch K4.

[0101] Combination Fig. 9 As shown, Fig. 9 for Figure 8 A switch timing diagram of the demultiplexer in the embodiment, 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 sequentially transmit effective signals to control the first switch K1, the second switch K2, the third switch K3 and the fourth switch K4 to be turned on sequentially.

[0102] In the embodiment of the present application, the demultiplexer 30 can transmit data signals to two adjacent sub-pixels 10 in the same column through different types of first signal lines 20, so the data writing processes of the two adjacent sub-pixels 10 in the same column can not affect each other. That is, the data writing processes of the two adjacent sub-pixel rows 12 do not affect each other, so that the opening time of the data writing transistor in the sub-pixel 10 can be increased, and then the time for the data signal to be written into the sub-pixel 10 can be increased, thereby improving the display unevenness problem caused by insufficient data signal writing in high-frequency and high-resolution products.

Exemplarily, the display device 02 provided in the embodiment of the present application can be an electronic device such as a mobile phone, a computer, a television, a car display area, a wearable electronic device, etc. This application does not make specific limitations.

[0105] In the display device 02, among the sub-pixels 10 in the same row, some of the sub-pixels 10 are electrically connected to the first type of signal line 21 located on one side of the sub-pixel column 11, and some of the sub-pixels 10 are electrically connected to the second type of signal line 22 located on the other side of the sub-pixel column 11. That is, in a sub-pixel row 12, there are both sub-pixels 10 connected to the first type of signal line 11 and sub-pixels 10 connected to the second type of signal line 22, which can reduce the charging difference of the sub-pixels 10 in different rows, thereby facilitating the reduction of the brightness difference between different sub-pixel rows 12, improving the horizontal stripe problem of the display panel 01, and improving the display quality.

[0106] Moreover, in the same sub-pixel row 12, some of the first color sub-pixels 101 are electrically connected to the first type of signal line 21, and some of the first color sub-pixels 101 are electrically connected to the second type of signal line 22. That is, in one sub-pixel row 12, there are both first color sub-pixels 101 connected to the first type of signal line 11 and first color sub-pixels 101 connected to the second type of signal line 22. This is beneficial to reducing the charging difference of the first color sub-pixels 101 in different rows, thereby helping to further reduce the brightness difference between different sub-pixel rows 12 and improve the horizontal stripe problem of the display panel 01.
