FIG. 1 is a schematic diagram of an exemplary pixel structure; as shown in fig. 1, the pixel structure includes a plurality of pixel units 10, a plurality of gate lines GL and a plurality of data lines DL; here, each pixel unit 10 includes a plurality of sub-pixels 100, and in the embodiment of the present disclosure, the sub-pixels 100 in each pixel unit 10 are, for example, a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. Here, the arrangement rule of the sub-pixels 100 in the pixel units 10 arranged side by side in the first direction X is the same. For example: the sub-pixels 100 (from left to right) in the first row of the pixel units 10 are arranged in the arrangement of the red, green, and blue sub-pixels R, G, and B, and the sub-pixels 100 (from left to right) in the second row of the pixel units 10 are arranged in the arrangement of the green, blue, and red sub-pixels G, B, and R. With continued reference to fig. 1, in the pixel structure, the sub-pixels 100 arranged side by side in the second direction Y have the same color, for example: the sub-pixels 100 arranged side by side in the second direction Y are all red sub-pixels R.

The color of the sub-pixel 100 depends on the color of the filter in the sub-pixel 100, and if the filter in the sub-pixel 100 is red, the sub-pixel 100 is referred to as a red sub-pixel R, and similarly, if the filter in the sub-pixel 100 is green, the sub-pixel 100 is referred to as a green sub-pixel G, and if the filter in the sub-pixel 100 is blue, the sub-pixel 100 is referred to as a blue sub-pixel B.

FIG. 2 is a schematic diagram of a sub-pixel of the pixel structure shown in FIG. 1; as shown in fig. 2, the subpixel 100 includes a thin film transistor TFT and a pixel electrode 20 disposed on a first substrate 11, a common electrode 40, a color filter 50 (shown as a red filter) and a black matrix BM disposed on a second substrate base 11', and liquid crystal molecules 30 disposed between the pixel electrode 20 and the common electrode 40. The gate electrode of the thin film transistor TFT is connected to the gate line GL, the source data line DL of the thin film transistor TFT, and the drain electrode of the thin film transistor TFT is connected to the pixel electrode 20. When the working level is applied to the gate line GL, the thin film transistor TFT is turned on, the data voltage written on the data line DL is applied to the pixel electrode 20, an electric field generated between the pixel electrode 20 and the common electrode 40 drives the liquid crystal molecules 30 to deflect, light emitted by the backlight source is emitted through the pixel electrode 20, the layer where the liquid crystal molecules 30 are located, the common electrode 40 and the red filter, and at this time, the sub-pixel 100 emits red light. When the pixel structure is applied to a display panel, a Printed Circuit Board (PCB) is bound to a first substrate to provide a driving signal for a signal line such as a gate line GL. And need use the mark of binding on the first basement edge in binding the technology, when lower polaroid was attached to the first basement this moment, need avoid binding the mark, the edge of first basement then can't be attached to lower polaroid this moment, along with display panel's narrow limit, then cause the problem of light leak this moment easily. To avoid the problem of light leakage, ink is usually applied to the edge of the first substrate (where there is no lower polarizer). However, the cohesiveness of the ink is poor, and in order to avoid the problem of glue failure, the position where the frame of the backlight module is cohered with the display panel needs to be kept away from the ink as much as possible, so that the backlight module is 0.25mm more than the display panel. However, the frame is only 0.87 mm to 0.97mm, at this time, the frame part invades into the display area, and the shielding distance of the local area is different due to the influence of the linearity and the bonding precision of the frame, as shown in fig. 1, the sub-pixels 100 arranged side by side in the second direction Y in the pixel structure have the same color, and at this time, the macro display is a rainbow line, and the colors displayed on the left and right sides of the display panel are not the same.

In view of the above problems, the following technical solutions are provided in the embodiments of the present disclosure.

In a first aspect, fig. 3 is a schematic diagram of a pixel structure according to an embodiment of the disclosure; as shown in fig. 3, the present disclosure provides a pixel structure including a plurality of pixel units 10; the plurality of pixel units 10 form a plurality of first pixel groups 1 arranged side by side along a first direction X, and the pixel units 10 in any one of the first pixel groups 1 are arranged side by side along a second direction Y; each pixel unit 10 includes a plurality of sub-pixels 100, and at least some of the plurality of sub-pixels 100 are different in color. For example: each pixel unit 10 includes 3 sub-pixels 100, which are a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B; in the following examples: each pixel unit 10 includes 4 sub-pixels 100, and the 4 sub-pixels 100 may include 2 green sub-pixels G,1 red sub-pixel R, and 1 blue sub-pixel B. In the embodiment of the present disclosure, each pixel unit 10 includes 3 sub-pixels 100, i.e., a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B.

The pixel structure is divided into a middle display area Q1 and edge display areas Q2 which are positioned at two opposite sides of the middle display area Q1 in the first direction X; for the first pixel group 1 located in the edge display region Q2, at least some of the sub-pixels 100 adjacently disposed in the second direction Y are different in color. For example: any sub-pixels 100 arranged side by side in the second direction Y constitute first sub-pixel 100 groups, each first pixel group 1 including three first sub-pixel 100 groups; for the three first sub-pixel 100 groups in each first pixel group 1 of the edge display region Q2, one of the first sub-pixel 100 groups (from top to bottom) has the red sub-pixel R and the blue sub-pixel B alternately disposed, one of the first sub-pixel 100 groups (from top to bottom) has the blue sub-pixel B and the red sub-pixel R alternately disposed, and the other first sub-pixel 100 group only includes the green sub-pixel G.

In the embodiment of the present disclosure, for any first pixel group 1 located in the edge display region Q2, at least some of the sub-pixels 100 adjacently disposed in the second direction Y have different colors, that is, for any first pixel group 1 located in the edge display region Q2, at least some of the sub-pixels 100 in the pixel units 10 adjacently disposed in the second direction Y have different arrangement rules, for example: the red sub-pixel R, the green sub-pixel G and the blue sub-pixel B in one pixel unit 10 are sequentially arranged from left to right, and the blue sub-pixel B, the green sub-pixel G and the red sub-pixel R in another pixel unit 10 are sequentially arranged from left to right. At this time, when the pixel structure in the embodiment of the present disclosure is applied to a display panel, even if the frame blocks part of the edge display region Q2, the risk of intensively blocking a plurality of sub-pixels 100 of the same color continuously arranged in the second direction Y is reduced, thereby reducing the range of occurrence of rainbow-marks.

The pixel structure in the embodiments of the present disclosure is described below with reference to specific examples. Note that, in each of the following examples, each pixel unit 10 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. Among them, a plurality of sub-pixels 100 arranged side by side in the second direction Y constitute one first sub-pixel 100 group.

The first example: referring to fig. 3, the pixel array includes a plurality of first pixel groups 1 arranged side by side along a first direction X, any one of the first pixels includes a plurality of pixel units 10 arranged side by side along a second direction Y, and each of the pixel units 10 includes three sub-pixels 100 arranged side by side along the first direction X, namely, a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. Any sub-pixels 100 arranged side by side along the second direction Y constitute a first sub-pixel 100 group. The pixel structure is divided into a middle display area Q1 and edge display areas Q2 located at two opposite sides of the middle display area Q1 in the first direction X. In any first pixel group 1 of the edge display region Q2, for any two adjacent pixel units 10 in the second direction Y, one of the two adjacent pixel units includes a red subpixel R, a green subpixel G, and a blue subpixel B that are sequentially arranged from left to right; the other includes a blue subpixel B, a green subpixel G, and a red subpixel R arranged in order from left to right. That is, for three first sub-pixel 100 groups located in the first pixel group 1 of the edge display region Q2, two of which are red sub-pixels R and blue sub-pixels B alternately arranged, the remaining one includes only green sub-pixels G. For the first pixel groups 1 located in the middle display area Q1, the arrangement rule of the pixel units 10 in each first pixel group 1 is the same as the arrangement rule of the pixel units 10 in the first pixel group 1 in the edge display area Q2. That is, the arrangement rule of the sub-pixels 100 in the respective pixel units 10 arranged side by side in the first direction X is the same. Therefore, the range of rainbow patterns caused when the frame shields the edge display area Q2 can be reduced, and the preparation of a pixel structure is facilitated.

In some examples, fig. 4 is another schematic diagram of a pixel structure according to an embodiment of the disclosure, and as shown in fig. 4, the pixel structure includes not only a plurality of pixel units 10, but also a plurality of gate lines GL and a plurality of data lines DL. The gate lines GL extend along a first direction X and are arranged side by side along a second direction Y; the plurality of data lines DL extend in the second direction Y and are arranged side by side in the first direction X. The first direction X and the second direction Y intersect each other, and at this time, the gate lines GL and the data lines DL intersect each other to define a plurality of sub-pixel regions 100a, and one sub-pixel 100 is disposed in each sub-pixel region 100a. The sub-pixels 100 arranged side by side in the first direction X are connected to the same gate line GL, i.e. the sub-pixels 100 in the same row have one gate line GL control. The odd sub-pixels 100 in the ith first sub-pixel 100 group and the even sub-pixels 100 in the (i + 1) th first sub-pixel 100 group are connected to the same data line DL; or, the even sub-pixels 100 in the ith first sub-pixel 100 group and the odd sub-pixels 100 in the (i + 1) th first sub-pixel 100 group are connected to the same data line DL; i is an integer greater than or equal to 1. That is, the sub-pixels 100 in a first sub-pixel 100 group are written with data from two data lines DL, and the data lines DL connecting the sub-pixels 100 adjacently disposed in the same first sub-pixel 100 group are different. Specifically, each sub-pixel 100 includes at least a thin film transistor TFT and a pixel electrode 20; the gate electrode of the thin film transistor TFT is connected to the gate line GL, the source electrode of the thin film transistor TFT is connected to the data line DL, and the drain electrode of the thin film transistor TFT is connected to the pixel electrode 20. The pixel electrodes 20 in each first sub-pixel 100 group constitute a pixel electrode 20 group, the pixel electrode 20 group including a first side and a second side oppositely disposed in the first direction X; the thin film transistors TFT in two sub-pixels 100 adjacently disposed in the second direction Y, one on the first side of the group of pixel electrodes 20 and the other on the second side of the pixel electrodes 20; the TFTs in each of the sub-pixels 100 arranged side by side in the first direction X are located on the first side or the second side of the pixel electrode 20 group in the first sub-pixel 100 group. In this case, referring to fig. 4, the thin film transistors TFT are disposed on both left and right sides of each data line DL except for the first data line DL and the last data line DL, and the thin film transistors TFT on both sides are alternately disposed, so that the display uniformity of the display panel having the pixel structure can be effectively applied.

Fig. 5 is a schematic diagram of another pixel structure according to an embodiment of the disclosure; as shown in fig. 5, in some examples, in the intermediate display region Q1, the colors of the sub-pixels 100 within each first sub-pixel 100 group may also be the same. For example: in the intermediate display region Q1, the subpixels 100 in the respective pixel units 10 are arranged in order of the red subpixel R, the green subpixel G, and the blue subpixel B in the first direction X.

The second example is: FIGS. 6 and 7 are schematic diagrams of another pixel structure of an embodiment of the disclosure; as shown in fig. 6 and 7, the pixel structure is substantially the same as the pixel structure of fig. 3, except that the color of the adjacent sub-pixels 100 in any one of the first pixel groups 111 is different in the pixel structure of fig. 6 and 7. For example: for any first pixel group 111, the sub-pixels 100 in the first pixel unit 10 from top to bottom are a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B from left to right; the sub-pixels 100 in the second pixel unit 10 are a green sub-pixel G, a blue sub-pixel B and a red sub-pixel R from left to right; the sub-pixels 100 in the second pixel unit 10 are a blue sub-pixel B, a red sub-pixel R, and a green sub-pixel G, respectively, from left to right. In some examples, the arrangement rule of the sub-pixels 100 in the respective pixel units 10 arranged side by side in the first direction X is the same.

With continued reference to fig. 6, in the pixel structure, the pixel units 10 in the first pixel group 1 located in the edge display region Q2 and the middle display region Q1 are arranged in the same manner. And the arrangement rule of the sub-pixels 100 in the pixel units 10 arranged side by side in the first direction X is the same. The arrangement mode enables the display uniformity of the display panel applying the pixel structure to be better.

Fig. 8 is a schematic diagram of another pixel structure according to the embodiment of the present disclosure; as shown in fig. 8, the arrangement rule of the pixel units 10 in the first pixel group 1 in the edge display region Q2 is different from the arrangement rule of the pixel units 10 in the first pixel group 1 in the middle display region Q1. In the intermediate display region Q1, the colors of the respective sub-pixels 100 located in the same first sub-pixel 100 group are the same. For example: any one of the pixel units 10 of the middle display region Q1 includes a red subpixel R, a green subpixel G, and a blue subpixel B arranged in sequence from left to right in the first direction X. The arrangement rule of the pixel units 10 in the edge display region Q2 is the same as that shown in fig. 6, and therefore, the description thereof is not repeated.

FIG. 9 is a schematic diagram of another pixel structure according to an embodiment of the disclosure; fig. 10 is a schematic region distribution diagram of a pixel structure according to an embodiment of the disclosure; as shown in fig. 9 and 10, the embodiment of the present disclosure further provides a pixel structure, which includes a plurality of pixel units 10, the plurality of pixel units 10 form a plurality of first pixel groups 1 arranged side by side along a first direction X, and the pixel units 10 in any first pixel group 1 are arranged side by side along a second direction Y. Each pixel unit 10 in the pixel structure includes a plurality of sub-pixels 100, and at least some of the sub-pixels 100 have different colors. For example: each pixel unit 10 includes 1 red subpixel R, 1 green subpixel G, and 1 blue subpixel B; for another example: each pixel cell 10 includes 1 red subpixel R, 2 green subpixels G, and 1 blue subpixel B. It is also exemplified that each pixel unit 10 includes 1 red subpixel R, 1 green subpixel G, and 1 blue subpixel B.

With continued reference to fig. 9, the pixel structure includes a middle display region Q1, and edge display regions Q2 located at two opposite sides of the middle display region Q1 in the first direction X. A plurality of pixel regions 10a are included in each of the middle display region Q1 and the edge display region Q2, and one pixel unit 10 is disposed in one pixel region 10a, for example: the pixel units 10 and the pixel regions 10a are disposed in one-to-one correspondence. Each of the pixel regions 10a includes a plurality of sub-pixel regions 100a arranged side by side in the first direction X. Wherein the number of the sub-pixel regions 100a in each pixel region 10a may be the same as the number of the sub-pixels 100 in each pixel unit 10. For example: the number of sub-pixels 100 in each pixel unit 10 in the embodiment of the present disclosure is 3, and the number of corresponding sub-pixel regions 100a in each pixel region 10a is also 3. Each sub-pixel 100 includes at least a pixel unit 10. For each pixel unit 10 in the first pixel group 1 in the edge display region Q2, the pixel electrodes 20 in at least some of the sub-pixels 100 are located in at least two sub-pixel regions 100a. For example: the pixel electrodes 20 in the sub-pixels 100 in the edge display region Q2 each include 3 sub-electrodes 21, that is, 9 sub-electrodes 21 are included in one pixel unit 10, and the 3 sub-electrodes 21 of each pixel electrode 20 in each pixel unit 10 are respectively located in the three sub-pixel regions 100a. It should be understood that the 3 sub-electrodes 21 of each pixel electrode 20 are electrically connected.

Since the pixel electrodes 20 of at least some of the sub-pixels 100 in the edge display area Q2 are located in at least two sub-pixel areas 100a, at least some of the sub-pixels 100 in each pixel unit 10 are not rectangular, so that the sub-pixels 100a in the edge display area Q2 that are arranged side by side along the second direction Y do not display the same color, and even if the frame blocks part of the edge display area Q2, the risk of intensively blocking a plurality of sub-pixels 100 that are continuously arranged in the second direction Y and have the same color is reduced, thereby reducing the range of occurrence of rainbow stripes.

In some examples, each of the pixel electrodes 20 includes a plurality of sub-electrodes 21; the sub-electrodes 21 in the same sub-pixel area 100a are arranged side by side along the second direction Y. And each sub-electrode 21 in the same sub-pixel area 100a belongs to a different sub-pixel 100. In order to make the structure in each pixel unit 10 of the edge display region Q2 more clear in the embodiment of the present disclosure; the following description will be made by taking an enlarged view of one pixel cell 10 illustrated in fig. 11 as an example. As shown in fig. 11, each pixel unit 10 includes a red subpixel R, a green subpixel G, and a blue subpixel B; the pixel electrodes 20 of the red, green and blue sub-pixels R, G and B each include 3 sub-electrodes 21, which are referred to as a first sub-electrode, a second sub-electrode and a second sub-electrode, respectively. First sub-electrodes of a red sub-pixel R, a blue sub-pixel B and a green sub-pixel G are sequentially arranged in a first sub-pixel area 100a from left to right, second sub-electrodes of the green sub-pixel G, the red sub-pixel R and the blue sub-pixel B are sequentially arranged in a second sub-pixel area 100a from top to bottom, and third sub-electrodes of the blue sub-pixel B, the green sub-pixel G and the red sub-pixel R are sequentially arranged in the second sub-pixel area 100a from top to bottom.

In some examples, the arrangement rules of the sub-pixels 100 in each pixel unit 10 in the edge display region Q2 of the pixel structure are the same. For example: the pixel unit 10 structure shown in fig. 11 may be employed for each pixel unit 10 located in the edge display region Q2. Thus, the preparation is convenient, and the display is uniform. Further, the arrangement rule of the sub-pixels 100 of the pixel unit 10 in the middle display area Q1 of the pixel structure may be the same as the arrangement rule of the sub-pixels 100 in each pixel unit 10 in the edge display area Q2. For example, each pixel unit 10 in the pixel structure may adopt the pixel unit 10 structure shown in fig. 11.

In some examples, in order to more clearly understand the specific structure of the pixel structure, each pixel unit 10 is designed according to the structure of the pixel unit 10 shown in fig. 11. Fig. 12 is another schematic diagram of a pixel structure according to an embodiment of the disclosure; as shown in fig. 12, the pixel structure may include not only the sub-pixel 100 described above, but also a plurality of gate lines GL extending in the first direction X and arranged side by side in the second direction Y, and a plurality of data lines DL extending in the second direction Y and arranged side by side in the first direction X. The gate lines GL and the data lines DL are arranged to cross to form a plurality of sub-pixel regions 100a. Each sub-pixel 100 includes not only the pixel electrode 20 but also a thin film transistor TFT, one of which is disposed in each sub-pixel region 100a. The gate electrode of the TFT is connected to the gate line GL, the source electrode of the TFT is connected to the data line DL, and the drain electrode of the TFT is connected to one of the sub-electrodes 21 of the corresponding sub-pixel 100. Preferably, the drain electrode of each thin film transistor TFT is connected to the sub-electrode 21 closest to the gate line GL to which the gate electrode of the thin film transistor TFT is connected. For example: referring to fig. 12, the thin film transistor TFT of the blue subpixel B is positioned in the first subpixel region 100a from left to right, and a drain thereof is connected to the first sub-electrode of the blue subpixel B; the thin film transistor TFT of the red subpixel R is located in the second subpixel region 100a from left to right, and a drain of the thin film transistor TFT is connected to the second sub-electrode of the red subpixel R; the thin film transistor TFT of the green subpixel G is located in the third subpixel region 100a from left to right, and a drain thereof is connected to the third sub-electrode of the green subpixel G.

Further, a plurality of first sub-electrodes arranged side by side in the first direction X constitute a group of sub-electrodes 21. Each sub-electrode 21 group includes a first side (left side) and a second side (right side) oppositely disposed in the first direction X; the thin film transistors TFT in the two sub-pixel regions 100a adjacently disposed in the second direction Y, one on the first side of the group of sub-electrodes 21 and the other on the second side of the group of sub-electrodes 21; the thin film transistors TFT in each of the subpixel areas 100a arranged side by side in the first direction X are located on the same side (first side or second side) as the group of the sub-electrodes 21. In this case, referring to fig. 12, the thin film transistors TFT are disposed on both left and right sides of each data line DL except for the first data line DL and the last data line DL, and the thin film transistors TFT on both sides are alternately disposed, so that the display uniformity of the display panel having the pixel structure can be effectively applied.

Further, with continued reference to fig. 12, the sub-pixel regions 100a arranged side by side in the second direction Y constitute a first sub-pixel region group 101a; the gates of the thin film transistors TFT of the sub-pixel regions 100a arranged side by side in the first direction X are connected to the same gate line GL; the sources of the thin film transistors TFTs in the odd-numbered sub-pixel regions 100a in the ith first sub-pixel region group 101a and the sources of the thin film transistors TFTs in the even-numbered sub-pixel regions 100a in the (i + 1) th first sub-pixel region group 101a are connected to the same data line DL; or, the sources of the thin film transistors TFTs in the even-numbered sub-pixel regions 100a in the ith first sub-pixel 100 group are connected to the same data line DL as the sources of the thin film transistors TFTs in the odd-numbered sub-pixel regions 100a in the (i + 1) th first sub-pixel region group 101a; i is an integer greater than or equal to 1. That is, the data writing is performed on the thin film transistors TFT of the sub-pixels 100 in one first sub-pixel region group 101a by two data lines DL, and the data lines DL connected to the sources of the thin film transistors TFT in the sub-pixel regions 100a adjacently disposed in the same first sub-pixel region group 101a are different.

It should be noted that, in any of the above examples, each sub-pixel 100 may include not only the thin film transistor TFT and the pixel electrode 20, but also the common electrode 40, the color filter 50, and other structures, which are not listed here. The color of the color filter 50 determines the color of the sub-pixel 100. Moreover, the shape of each color filter 50 corresponds to the shape of the pixel electrode 20 of the sub-pixel 100 in which it is located. For example: the pixel electrode 20 is rectangular, and the color filter 50 is also rectangular. For another example: the pixel electrode 20 includes 3 sub-electrodes 21, the corresponding color filter 50 includes sub-structures corresponding to the sub-electrodes 21 one to one, and the sub-electrodes 21 are disposed corresponding to the shapes of the sub-structures.

In a second aspect, an embodiment of the disclosure further provides a display device, which includes at least one display panel, and any display panel includes any pixel structure described above.

Further, the display device may be a tiled screen, i.e. comprising a plurality of display panels. Since the pixel structure in the display panel is the above structure, the risk of intensively shielding a plurality of sub-pixels 100 of the same color continuously arranged in the second direction Y is reduced, thereby reducing the range of occurrence of rainbow fringes.

It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
