All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0026] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0029] It should be understood that although terms such as "first," "second," etc., may be used to describe directions, pixel units, scan lines, etc., in the embodiments of this application, these directions, pixel units, scan lines, etc., should not be limited to these terms. These terms are only used to distinguish directions, pixel units, scan lines, etc., from each other. For example, without departing from the scope of the embodiments of this application, a first direction may also be referred to as a second direction, and similarly, a second direction may also be referred to as a first direction.

[0030] Through meticulous and in-depth research, the applicant in this case has provided a solution to the problems existing in the prior art.

[0031] Figure 1 This is a schematic diagram of a display panel provided in an embodiment of this application. Figure 2 This is a schematic diagram of a sub-pixel connection related to this application. Figure 3 This is a schematic diagram of a multiplexer provided in an embodiment of this application. Figure 4A driving timing diagram of a display panel is provided in the embodiments of the present application.

[0032] The embodiments of the present application provide a display panel 01, as shown in Figure 1 The display panel 01 includes a plurality of pixel units P, a plurality of scan lines G and a plurality of data lines S. The pixel unit P includes a plurality of sub-pixels 10. The sub-pixels 10 in the same pixel unit P are electrically connected to the same scan line G, and each sub-pixel 10 in the same pixel unit P is electrically connected to a different data line S. The scan lines G and the data lines S are arranged in layers.

[0033] Specifically, as shown in Figure 1 and Figure 2 The sub-pixel 10 includes a switching module K1 and a pixel electrode K2. The input end of the switching module K1 is electrically connected to the data line S, the output end is electrically connected to the pixel electrode K2, and the control end is electrically connected to the scan line G.

[0034] Further, the switching module K1 includes a transistor T. The first pole of the transistor T is electrically connected to the data line S, the second pole is electrically connected to the pixel electrode K2, and the gate is electrically connected to the scan line G. When the scan line G transmits an effective signal to control the transistor T to be turned on, the data signal transmitted by the data line S can be transmitted to the pixel electrode K2 of the sub-pixel 10 through the turned-on transistor T.

[0035] Please continue to refer to Figure 1 The display panel 01 further includes a demultiplexer Q. The demultiplexer Q includes one input end Q1 and two output ends Q2. The two output ends Q2 are respectively electrically connected to different data lines S. The demultiplexer Q is used to transmit data signals to different data lines S.

[0036] Alternatively, the two output ends Q2 of the same demultiplexer Q are respectively electrically connected to two adjacent data lines S. The two output ends Q2 are used to transmit the data signal received by the input end Q1 to the data line S connected thereto in time division.

[0037] As shown in Figure 3 and Figure 4 The demultiplexer Q includes a first transistor M1 and a second transistor M2. The first pole of the first transistor M1 is electrically connected to the input end Q1 of the demultiplexer Q, the second pole is electrically connected to one of the output ends Q2 of the demultiplexer Q, and the gate is electrically connected to the first control line CKV1. The first pole of the second transistor M2 is electrically connected to the input end Q1 of the demultiplexer Q, the second pole is electrically connected to the other output end Q2 of the demultiplexer Q, and the gate is electrically connected to the second control line CKV2.

[0038] In one frame of the display panel 01, the first control line CKV1 and the second control line CKV2 transmit valid signals (such as low-level signals) in turn to control the first transistor M1 and the second transistor M2 to open at different times, and the multiplexer Q transmits the data signal received by the input end Q1 to different data lines S at different times.

[0039] It should be noted that the display panel 01 can include a plurality of multiplexers Q, the gates of the first transistors M1 in different multiplexers Q can be electrically connected to the same first control line CKV1, and the first control line CKV1 transmitting a valid signal can control the first transistors M1 in the plurality of multiplexers Q connected thereto to open at the same time. The gates of the second transistors M2 in different multiplexers Q can be electrically connected to the same second control line CKV2, and the second control line CKV2 transmitting a valid signal can control the second transistors M2 in the plurality of multiplexers Q connected thereto to open at the same time.

[0040] Among them, the plurality of sub-pixels 10 included in the same pixel unit P include at least three sub-pixels 10 of different colors.

[0041] Optionally, the same pixel unit P can include a red sub-pixel, a green sub-pixel, and a blue sub-pixel.

[0042] In addition, the same sub-pixel 10 only belongs to one pixel unit P, and there is no problem of mutual borrowing of sub-pixels 10 among the pixel units P.

[0043] In the embodiments of the present application, the same pixel unit P includes at least three sub-pixels 10 of different colors, so that the display panel 01 can realize full-color display, and each pixel unit P does not need to borrow sub-pixels 10 from each other, which is conducive to reducing the driving difficulty of the display panel 01, thereby reducing the probability of problems occurring during the operation of the pixel unit P, and further improving the stability of the display quality.

[0044] Moreover, the 1:2 multiplexer Q is arranged to transmit the data signal to the sub-pixel 10, which can not only reduce the port of the driving chip for providing the data signal to the display panel 01 to a certain extent, but also ensure that each sub-pixel 10 has sufficient charging time, especially conducive to ensuring that each sub-pixel 10 has sufficient charging time when the display panel 01 with high pixel density displays at high frequency, thereby ensuring that each sub-pixel 10 receives a data signal meeting the requirements, and further ensuring the display quality of the display panel 01.

[0045] Please continue to refer to Figure 1 In an embodiment of the present application, the shape of the sub-pixel 10 is a square. That is, the length of the sub-pixel 10 in the row direction and the column direction of the display panel 01 is the same.

[0046] In the prior art, the sub-pixels in the display panel are usually arranged in a stripe arrangement, and the size of the sub-pixel in the length direction is much larger than the size in the width direction.

[0047] The present inventors have found that, for the stripe sub-pixel, the size in the width direction relative to the size in the length direction will bring more process capability limitations to the preparation of the sub-pixel. When realizing a smaller size of the stripe sub-pixel, the size in the width direction is first limited by the process equipment and process capability, and cannot be further reduced. At this time, the size in the length direction has not reached the limit of the process capability, and still has a compression space.

[0048] Therefore, the embodiment of the present application sets the sub-pixel 10 as a square, and under the same process condition, the size of the sub-pixel 10 in the row direction and the column direction can reach the limit of the process capability, and a smaller area can be realized relative to the stripe sub-pixel, thereby being beneficial to improve the density of the sub-pixel 10 in the unit area of the display panel 01, and further beneficial to make the display panel 01 have a higher pixel density.

[0049] In an embodiment of the present application, please continue to refer to Figure 1 The plurality of data lines S are arranged along the first direction X, and the data lines S extend along the second direction Y, and the first direction X intersects the second direction Y.

[0050] Optionally, the first direction X is the row direction of the display panel 01, and the second direction Y is the column direction of the display panel 01.

[0051] The at least three color different sub-pixels 10 of the pixel unit P include a first color sub-pixel 11, a second color sub-pixel 12 and a third color sub-pixel 13. In the same pixel unit P, the data lines S respectively electrically connected to the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 are adjacent in the first direction X.

[0052] That is to say, the plurality of data lines S electrically connected to the same pixel unit P can be arranged adjacent in the first direction X, and no other data line S is arranged between the data lines S.

[0053] Optionally, the first color sub-pixel 11 is a red sub-pixel, the second color sub-pixel 12 is a green sub-pixel, and the third color sub-pixel 13 is a blue sub-pixel.

[0054] In the embodiments of the present application, the plurality of data lines S to which the sub-pixels 10 in the same pixel unit P are electrically connected are adjacent, and the maximum distance between the plurality of data lines S as a whole and the pixel units P to which the plurality of data lines S are electrically connected is relatively short, which is beneficial to reducing the length of the connection lines between the plurality of data lines S and the pixel units P, thereby being beneficial to saving materials and reducing the manufacturing difficulty of the display panel 01.

[0055] In an embodiment of the present application, as shown in Figure 1 In the display panel 01, the pixel units P are arranged in the first direction X and the second direction Y, and in the same pixel unit P, the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 are arranged in the first direction X.

[0056] At least part of the pixel units P arranged in the first direction X are electrically connected to the same scan line G, that is, the scan line G can extend in the first direction X, and the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 arranged in the first direction X can be electrically connected to the same scan line G.

[0057] In addition, at least part of the sub-pixels 10 arranged in the second direction Y are electrically connected to the same data line S.

[0058] Optionally, the sub-pixels 10 arranged in the second direction Y are of the same color. That is, in the pixel units P arranged in the second direction Y, each first color sub-pixel 11 can be located in the same column, each second color sub-pixel 12 can be located in the same column, and each third color sub-pixel 13 can be located in the same column.

[0059] In the embodiments of the present application, the scan line G can extend in the first direction X, and a plurality of scan lines G can be arranged in the second direction Y. In combination with Figures 1-4 As shown in the figure, during the period in which the scan line G transmits an effective signal (such as a low level), the first transistor M1 and the second transistor M2 in the demultiplexer Q are opened in turn, and the two output ends Q2 of the demultiplexer Q are controlled to transmit data signals to the data lines S to which the two output ends Q2 are electrically connected in turn. Since the first transistor M1 in each demultiplexer Q in the display panel 01 can be opened at the same time, and the second transistor M2 in each demultiplexer Q can be opened at the same time, during the period in which the scan line G transmits an effective signal (such as a low level), the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 in the same pixel unit P can all receive data signals, thereby realizing full-color display of the display panel 01.

[0060] Figure 5 Another schematic diagram of a display panel provided in an embodiment of the present application.

[0061] In an embodiment of the present application, as shown in Figure 5As shown, in the display panel 01, two of the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 of the same pixel unit P are arranged along the first direction X, and the other one is arranged along the second direction Y with one of the two.

[0062] For example, in the same pixel unit P, the first color sub-pixel 11 and the second color sub-pixel 12 are arranged along the first direction X, and the third color sub-pixel 13 and the first color sub-pixel 11 are arranged along the second direction Y.

[0063] In other words, the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 in the same pixel unit P can be arranged in an "L" shape.

[0064] Two adjacent pixel units P in the second direction Y can form a pixel unit group PN. In the same pixel unit group PN, each first color sub-pixel 11, second color sub-pixel 12 and third color sub-pixel 13 forms a rectangular arrangement.

[0065] Optionally, such as Figure 5 As shown, the pixel unit group PN, composed of two pixel units P, includes two first color sub-pixels 11, two second color sub-pixels 12, and two third color sub-pixels 13. These sub-pixels are arranged in 3 rows and 2 columns in a rectangular pattern.

[0066] In this embodiment, the distance between sub-pixels 10 in the same pixel unit P can be set to be relatively short, which is beneficial to improving the light mixing effect between sub-pixels 10, thereby improving the display quality of the display panel 01. At the same time, setting the sub-pixels 10 in the pixel unit group PN to be arranged in a rectangular pattern can ensure that the pixel units P are arranged closely, thereby improving the sharpness of the displayed image and further ensuring the display effect.

[0067] Alternatively, please continue to refer to Figure 5 In the same pixel unit group PN, the sub-pixels 10 arranged along the second direction Y have different colors. This helps to make the distribution of sub-pixels of different colors in the pixel unit group PN more uniform, thereby further improving the light mixing effect between each sub-pixel 10 and thus improving the display quality of the display panel 01.

[0068] Alternatively, please continue to refer to Figure 5 In two adjacent pixel unit groups PN in the first direction X, the color of one of them is different from that of the adjacent sub-pixel 10 in the first direction X.

[0069] For example, such as Figure 5As shown, the plurality of pixel unit groups PN includes a first pixel unit group PN1 and a second pixel unit group PN2 adjacent in the first direction X, a first color sub-pixel 11 in the first pixel unit group PN1 is adjacent to a third color sub-pixel 13 in the second pixel unit group PN2, a second color sub-pixel 12 in the first pixel unit group PN1 is adjacent to a first color sub-pixel 11 in the second pixel unit group PN2, and a third color sub-pixel 13 in the first pixel unit group PN1 is adjacent to a second color sub-pixel 12 in the second pixel unit group PN2.

[0070] Of course, in two pixel unit groups PN adjacent in the second direction Y, the colors of the sub-pixels 10 adjacent in the second direction Y in one of the two pixel unit groups PN can also be different from those in the other pixel unit group PN.

[0071] In this way, it is beneficial to make the distribution of sub-pixels 10 of different colors in the display panel 01 more uniform, thereby facilitating further improvement of the display quality of the display panel 01.

[0072] In an embodiment of the present application, as shown in Figure 5 A plurality of scan lines G are arranged along the second direction Y, and the plurality of scan lines G includes a first scan line G1 and a second scan line G2 adjacent along the second direction Y, and the first scan line G1 and the second scan line G2 are electrically connected to the same pixel unit group PN.

[0073] The two pixel units P in the same pixel unit group PN are a first pixel unit P1 and a second pixel unit P2, and in the pixel unit groups PN arranged at least partially along the first direction X, the first pixel unit P1 is electrically connected to the first scan line G1, and the second pixel unit P2 is electrically connected to the second scan line G2.

[0074] In the embodiment of the present application, when the first scan line G1 transmits an effective signal to control the transistor T in the first pixel unit P1 to be turned on, the output end Q2 of the demultiplexer Q transmits a data signal to the data line S electrically connected to the transistor T in the first pixel unit P1, thereby realizing the normal work of the first pixel unit P1. When the second scan line G2 transmits an effective signal to control the transistor T in the second pixel unit P2 to be turned on, the output end Q2 of the demultiplexer Q transmits a data signal to the data line S electrically connected to the transistor T in the second pixel unit P2, thereby realizing the normal work of the second pixel unit P1. Of course, the data lines S connected to the first pixel unit P1 and the second pixel unit P2 can be the same.

[0075] Figure 6 For Figure 5 A planar layout schematic diagram of the display panel is shown.

[0076] Please refer to Figure 5 and Figure 6In one embodiment of this application, the scan line G includes a main body Z1 extending along a first direction X and a plurality of branches Z2 connected to the main body Z1. The sub-pixel 10 includes a switching module K1, which includes an active layer YC. The active layer YC can be the active layer of the transistor T included in the switching module K1 in the above embodiment.

[0077] In this process, the active layer YC in at least a portion of the sub-pixels 10 arranged along the first direction X overlaps with the main body Z1 of the same scan line G in the thickness direction of the display panel 01. Furthermore, in the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 of the same pixel unit P, the active layer YC in the sub-pixels 10 of the other two that are not arranged along the first direction X overlaps with the branch Z2 of the scan line G1 in the thickness direction of the display panel 01.

[0078] For example, such as Figure 6 As shown, in the first pixel unit P1, the first color sub-pixel 11 and the second color sub-pixel 12 are arranged along the first direction X. The active layer YC of the switching module K1 in the first color sub-pixel 11 and the second color sub-pixel 12 overlaps with the main body Z1 of the scan line G in the thickness direction of the display panel 01. The third color sub-pixel 13 and the first color sub-pixel 11 are arranged along the second direction Y. The active layer YC of the switching module K1 in the third color sub-pixel 13 overlaps with the branch Z2 of the scan line G in the thickness direction of the display panel 01.

[0079] In other words, the sub-pixels 10 arranged along the first direction X can be scanned by the main body Z1 of the scan line G. In the same pixel unit P, the sub-pixels 10 that are not arranged along the first direction X can be scanned by the branch Z2 of the scan line G.

[0080] In this embodiment, while realizing the function of transmitting scanning signals from the scan line G to the sub-pixel 10, the structure of the scan line G is relatively simple, which helps to reduce the difficulty and cost of manufacturing the scan line G.

[0081] Optionally, such as Figure 6 As shown, branch Z2 of the first scan line G1 is located on the side of its main body Z1 facing the second scan line G2, and branch Z2 of the second scan line G2 is located on the side of its main body Z1 facing the first scan line G1. Along the first direction X, branches Z2 of the first scan line G1 and branches of the second scan line G2 are arranged alternately. This helps to reduce the space occupied by the first scan line G1 and the second scan line G2 as a whole in the second direction Y, thereby enabling the display panel 01 to have a higher pixel density.

[0082] Figure 7 This is a schematic diagram of another display panel provided in an embodiment of this application.

[0083] In an embodiment of the present application, as shown in Figure 7 two of the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 in the same pixel unit P are arranged along the second direction Y, the other one is arranged along the first direction X with the two, and both of the two are overlapped in the first direction X. That is, the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 in the same pixel unit P can be arranged in a "pin" shape.

[0084] The two pixel units P adjacent in the second direction Y form a pixel unit group PN, and the two pixel units P forming the pixel unit group PN can be the first pixel unit P1 and the second pixel unit P2 respectively.

[0085] In the same pixel unit group PN, the arrangement structure of the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 in the first pixel unit P1 is the same as that of the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 in the second pixel unit P2 after being flipped 180° along the first direction X.

[0086] In the embodiment of the present application, the sub-pixels 10 in the same pixel unit P are arranged in a "pin" shape, so that the distance between the sub-pixels 10 in the pixel unit P can be set smaller, which is beneficial to improve the light mixing effect between the sub-pixels 10, thereby improving the display quality of the display panel 01. Meanwhile, the arrangement structure of the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 in the first pixel unit P1 is the same as that of the first color sub-pixel 11, the second color sub-pixel 12 and the third color sub-pixel 13 in the second pixel unit P2 after being flipped 180° along the first direction X, which is beneficial to arrange the pixel units P closely to ensure the fineness of the display picture, thereby further ensuring the display effect of the display panel 01.

[0087] Alternatively, please continue to refer to Figure 7 In the same pixel unit group PN, the colors of the sub-pixels 10 arranged along the second direction Y are different from each other. In this way, it is beneficial to make the distribution of sub-pixels of different colors in the pixel unit group PN more uniform, thereby further improving the light mixing effect between the sub-pixels 10, and further improving the display quality of the display panel 01.

[0088] Figure 8 As shown in Figure 7 a planar layout schematic diagram of the display panel.

[0089] In combination with Figure 7 and Figure 8As shown, in one embodiment of the present application, a plurality of scan lines G are arranged along the second direction Y, and the plurality of scan lines G include a first scan line G1 and a second scan line G2 adjacent along the second direction Y.

[0090] Among the pixel unit groups PN arranged at least partially along the first direction X, the first pixel unit P1 is electrically connected to the first scan line G1, and the second pixel unit P2 is electrically connected to the second scan line G2. Of course, among the pixel unit groups PN arranged along the first direction X, each first pixel unit P1 is arranged along the first direction X, and each second pixel unit P2 is arranged along the first direction X.

[0091] In the embodiment of the present application, when the first scan line G1 transmits an effective signal to control the transistor T in the first pixel unit P1 to be turned on, the output end Q2 of the demultiplexer Q transmits a data signal to the data line S electrically connected to the transistor T in the first pixel unit P1, so as to realize the normal work of the first pixel unit P1. When the second scan line G2 transmits an effective signal to control the transistor T in the second pixel unit P2 to be turned on, the output end Q2 of the demultiplexer Q transmits a data signal to the data line S electrically connected to the transistor T in the second pixel unit P2, so as to realize the normal work of the second pixel unit P1. Of course, the data lines S connected to the first pixel unit P1 and the second pixel unit P2 can be the same.

[0092] In one embodiment of the present application, please continue to combine Figure 8 and Figure 9 The same scan line G includes a plurality of electrically connected first parts R1 and winding parts R2, the first parts R1 extend along the first direction X, and the winding parts R2 are arranged alternately with the first parts R1 along the first direction X. The sub-pixel 10 includes a switching module K1, and the switching module K1 includes an active layer YC, which can be the active layer of the transistor T included in the switching module K1 in the above-mentioned embodiment.

[0093] Among the first color sub-pixel 11, the second color sub-pixel 12, and the third color sub-pixel 13 of the same pixel unit P, the active layer YC in two of them arranged along the second direction Y overlaps the winding part R2 of the scan line G in the thickness direction of the display panel 01, and the active layer YC in the other one overlaps the first part R1 of the scan line G in the thickness direction of the display panel 01.

[0094] For example, in the same pixel unit P, the first color sub-pixel 11 and the second color sub-pixel 12 are arranged along the second direction Y, and the active layer YC of the switching module K1 in the first color sub-pixel 11 and the second color sub-pixel 12 is overlapped with the winding portion R1 of the scanning line G in the thickness direction of the display panel 01; the third color sub-pixel 13 is arranged along the first direction X and is overlapped with the first color sub-pixel 11 and the second color sub-pixel 12 in the first direction X, and the active layer YC of the switching module K1 in the third color sub-pixel 13 is overlapped with the first portion R1 of the scanning line G in the thickness direction of the display panel 01.

[0095] That is, in the same pixel unit P, the sub-pixel 10 arranged along the second direction Y can be provided with a scanning signal by the winding portion R2 of the scanning line G, and the other sub-pixels 10 can be provided with a scanning signal by the first portion R1 of the scanning line G.

[0096] In the embodiment of the present application, while realizing the function of transmitting the scanning signal from the scanning line G to the sub-pixel 10, the structure of the scanning line G can be designed to be relatively simple, which is beneficial to reduce the preparation difficulty and preparation cost of the scanning line G.

[0097] Figure 8 For Figure 9 the position relationship between the scanning line and the active layer is shown in the schematic view.

[0098] Optionally, as Figure 10 shown, the same winding portion R2 includes a first winding R21 extending along the first direction X and a second winding R22 extending along the second direction Y, and the first winding R21 is electrically connected with the second winding R22. The winding portion R2 can be a "mouth" type structure.

[0099] Among them, the first winding R21 is overlapped with the active layer YC in the sub-pixel 10 in the thickness direction of the display panel 01, and the second winding R22 is electrically connected with the adjacent first portion R1.

[0100] In this way, in the same pixel unit P, the sub-pixel 10 arranged along the second direction Y can be provided with a scanning signal by the first winding R21, and the second winding R22 is used to connect the first winding R21 and the first portion R1.

[0101] Figure 8 For Figure 10 the position relationship between the scanning line and the data line is shown in the schematic view.

[0102] In an embodiment of the present application, as Figure 11 shown, along the thickness direction of the display panel 01, the second winding R22 is at least partially overlapped with the data line S.

[0103] Since the data line S and the second winding R22 both extend along the second direction Y, the two are arranged to at least partially overlap in the thickness direction of the display panel 01, so that the space occupied by the two as a whole in the first direction X of the display panel 01 can be reduced, thereby facilitating improvement of the aperture ratio of the sub-pixel in the display panel 01 (i.e., the proportion of the light-transmitting region of the sub-pixel).

[0104] Figure 11 A schematic diagram of the positional relationship between a scanning line and a data line related to the present application.

[0105] In an embodiment of the present application, as shown in Figure 8 , the winding portion R2 includes a plurality of first windings R21 and second windings R22. In the same winding portion R2, the opening L is included between part of the second windings R22 and the first windings R21, and the opening L at least partially overlaps the data line S in the thickness direction of the display panel 01.

[0106] In an embodiment of the present application, the opening L is arranged between part of the second windings R22 and the first windings R21, and the opening L at least partially overlaps the data line S, so that the parasitic capacitance between the second windings R22 and the data line S can be reduced while ensuring the connection effect of the second windings R22 and the first windings R21 and the first portion R1.

[0107] Optionally, in combination with Figure 11 and Figure 12 , among the first scanning line G1 and the second scanning line G2 electrically connected to the same pixel unit group PN, the first scanning line G1 is flipped by 180° along the first direction X and flipped by 180° along the second direction Y, and has the same structure as the second scanning line G2.

[0108] Figure 12 A schematic diagram of another positional relationship between a scanning line and a data line related to the present application.

[0109] In another embodiment of the present application, as shown in Figure 5 , along the thickness direction of the display panel 01, among the plurality of winding portions R2 overlapped by the same data line S, the opening L in part of the winding portions R2 overlaps the data line S, and the opening L in part of the winding portions R2 does not overlap the data line S.

[0110] For example, along the thickness direction of the display panel 01, the winding portion R2 of the first scanning line G1 and the winding portion R2 of the second scanning line G2 are both overlapped by the same data line S, wherein the opening L in the winding portion R2 of the first scanning line G1 overlaps the data line S, and the opening L in the winding portion R2 of the second scanning line G2 does not overlap the data line S. Of course, the opening L in the winding portion R2 of the second scanning line G2 can overlap the data line adjacent to the data line S.

[0111] The embodiment of the present application can make each data line S overlap with the opening L in the winding portion R2, thereby facilitating the parasitic capacitance between each data line S and the winding portion R2 to be the same, making the parasitic capacitance between the data line S and the winding portion R2 in the display panel 01 more evenly distributed, thereby facilitating the brightness uniformity of the display panel 01 to be ensured.

[0112] In an embodiment of the present application, as shown in Figure 7 and Figure 5 In the same pixel unit group PN, the sub-pixels 10 arranged along the second direction Y and located in different pixel units P are electrically connected with the same data line S, and the sub-pixels 10 located in different pixel units P in the remaining sub-pixels 10 are electrically connected with the same data line S.

[0113] For example, as shown in Figure 6 In the first pixel unit group PN1, the first color sub-pixel 11, the third color sub-pixel 13 in the first pixel unit P1 and the second color sub-pixel 12 in the second pixel unit P2 are arranged along the second direction Y; the second color sub-pixel 12 in the first pixel unit P1 and the first color sub-pixel 11, the third color sub-pixel 13 in the second pixel unit P2 are arranged along the second direction Y.

[0114] Among them, the first color sub-pixel 11 in the first pixel unit P1 and the second color sub-pixel 12 in the second pixel unit P2 are electrically connected with the same data line S; the second color sub-pixel 12 in the first pixel unit P1 and the first color sub-pixel 11 in the second pixel unit P2 are electrically connected with the same data line S; the third color sub-pixel 13 in the first pixel unit P1 and the third color sub-pixel 13 in the second pixel unit P2 are electrically connected with the same data line S.

[0115] In the connection mode of the data line S and the sub-pixel 10, the data line S can be electrically connected with the sub-pixels 10 in its adjacent column, the data line S can also be electrically connected with the sub-pixels 10 in its adjacent two columns, and the data line S can also be electrically connected with the sub-pixels 10 in its non-adjacent column.

[0116] As shown in Figure 8 and Figure 13 When the data line S electrically connected with the sub-pixel 10 is not adjacent to the sub-pixel 10 in the first direction X, that is, there are other data lines between the sub-pixel 10 and the data line S electrically connected with the sub-pixel 10, the sub-pixel 10 is electrically connected with the data line S through the jumper JX. In this way, the short circuit between different data lines S can be avoided.

[0117] Optionally, the jumper JX is located on the side of the data line S close to the light emitting surface of the display panel 01.

[0118] Figure 13A local structure schematic diagram of a display panel provided in an embodiment of the present application.

[0119] Specifically, as shown in Figure 13 , the display panel 01 includes a substrate C (such as a glass substrate) and a light shielding layer SL located on one side of the substrate C, a scan line G (serving as a gate of a transistor at a position overlapping with an active layer of the transistor), a data line S, a pixel electrode K2, the data line S being located on a side of the scan line G away from the substrate C, the pixel electrode K2 being located on a side of the data line S away from the substrate C, and a jumper JX being located between a film layer where the data line S is located and a film layer where the pixel electrode K2 is located.

[0120] Further, as shown in Figure 13 , the display panel 01 can be a liquid crystal display panel, and the display panel 01 further includes a common electrode COM, a color filter substrate CM, a liquid crystal layer LY and a support column PS and the like structure sandwiched between the substrate C and the color filter substrate CM, and the color filter substrate CM can include an upper substrate CG, a black matrix BM, a red color resistance RCF, a green color resistance GCF, a blue color resistance BCF and an adhesive layer OC.

[0121] In an embodiment of the present application, please continue to refer to Figure 6 and Figure 8 , Figure 7 , at least part of the jumper JX overlaps with the scan line G in the thickness direction H of the display panel 01.

[0122] When the display panel 01 is a liquid crystal display panel, the light emitting device is arranged on the backlight module, and the present embodiment arranges at least part of the jumper JX to overlap with the scan line G, so that the shielding of the light emitted by the backlight module as a whole by the jumper JX and the scan line G can be reduced, which is conducive to ensuring the light transmittance of the liquid crystal display panel and improving the aperture ratio of the sub-pixel.

[0123] Please continue to refer to Figure 14 , in an embodiment of the present application, the pixel units P arranged at least partially along the second direction Y form a pixel unit column PL, in the same pixel unit column PL, the first color sub-pixel 11 and the second color sub-pixel 12 arranged along the second direction Y are electrically connected to the same data line S, and the third color sub-pixel 13 in the same pixel unit column PL is electrically connected to the same data line S. Or, in the same pixel unit column PL, the second color sub-pixel 12 and the third color sub-pixel 13 arranged along the second direction Y are electrically connected to the same data line S, and the first color sub-pixel 11 in the same pixel unit column PL is electrically connected to the same data line S.

[0124] In this embodiment, in a portion of the pixel unit column PL, a first color sub-pixel 11 and a second color sub-pixel 12 arranged along the second direction Y are electrically connected to the same data line S, while the remaining third color sub-pixels 13 are electrically connected to the same data line S; in another portion of the pixel unit column PL, a second color sub-pixel 12 and a third color sub-pixel 13 arranged along the second direction Y are electrically connected to the same data line S, while the remaining first color sub-pixels 11 are electrically connected to the same data line S. This allows for flexible connection of the data line S and sub-pixels 10 based on the positional relationship between the pixel unit column PL and its electrically connected data line S, thereby minimizing the connection line length between the pixel unit column PL and the data line S while increasing the diversity of display panel structures.

[0125] Figure 14 This is a schematic diagram of a display device provided in an embodiment of this application.

[0126] This application provides a display device 02, such as... ​ As shown, the display device 02 includes the display panel 01 provided in the above embodiments. Exemplarily, the display device 02 provided in the embodiments of this application can be an electronic device such as a mobile phone, computer, television, or vehicle display, and this application does not make any specific limitations.

[0127] In the display device 02, if the same pixel unit P is configured to include at least three sub-pixels 10 of different colors, then while achieving full-color display of the display panel 01, each pixel unit P does not need to borrow sub-pixels 10 from each other. This helps to reduce the driving difficulty of the display panel 01, thereby reducing the probability of problems when driving the pixel unit P, and thus improving the stability of display quality.

[0128] Furthermore, by setting a 1:2 multiplexer Q to transmit data signals to the sub-pixels 10, the number of ports from which the driver chip provides data signals to the display panel 01 can be reduced to a certain extent. This also ensures that each sub-pixel 10 has sufficient charging time. In particular, this is beneficial for ensuring that each sub-pixel 10 has sufficient charging time when the high-pixel-density display panel 01 is displayed at high frequencies. This helps ensure that each sub-pixel 10 receives the required data signal, thereby helping to ensure the display quality of the display panel 01.

[0129] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
