The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As mentioned in the background, the conventional display panel has a problem of edge color when displaying a picture. The inventors have intensively studied and found that the above technical problem is caused because the display panel includes a plurality of pixel units each including a plurality of sub-pixels. For example, when the display panel includes red, green, and blue sub-pixels, each pixel unit may include the red, green, and blue sub-pixels. In a partial pixel structure, due to the requirements of pixel arrangement and sizes of sub-pixels with different colors, and in order to ensure the integrity of a pixel unit, a problem that a single-color sub-pixel is arranged in a protruding manner exists in an edge area of a display panel, so that a single-color line can be observed at the edge of the display area when the display panel displays a picture, namely, a problem of edge color edge exists. Fig. 1 is a schematic diagram of a pixel structure of a conventional display panel. As shown in fig. 1, the display area of the display panel 10 is a rectangular display area, and a plurality of sub-pixels with different colors are arranged on the display panel 10 in an array manner, wherein the sub-pixels include a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B form a pixel unit 11, and the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B are arranged in a delta shape; thus, in the pixel unit 11 of the first row, the green sub-pixel G protrudes outward relative to the blue sub-pixel B, and in the pixel unit 11 of the last row, the red sub-pixel R protrudes outward relative to the blue sub-pixel B, so that the upper edge of the display area presents a green edge, the lower edge presents a red edge, and the problem of the display area edge color edge occurs.
In view of the above technical problem, the present invention provides a pixel structure. The pixel structure comprises a plurality of pixel units which are arranged along the row direction and the column direction, each pixel unit comprises a first sub-pixel, a second sub-pixel and a third sub-pixel, the first sub-pixel and the second sub-pixel are positioned in one row or one column in each pixel unit, the third sub-pixel is positioned in the other row or the other column which is adjacent to the first sub-pixel, and the light-emitting colors of the first sub-pixel, the second sub-pixel and the third sub-pixel are different from each other; the pixel units comprise a first pixel unit positioned on at least one side edge of the pixel structure and a second pixel unit far away from at least one side edge, the first pixel unit further comprises a pixel compensation part which is connected with the third sub-pixel and emits light with the same color, and the third sub-pixel and the connected pixel compensation part form a fourth sub-pixel; in each first pixel unit, the first sub-pixel or the second sub-pixel protrudes outwards relative to the third sub-pixel to form a concave part at least one side edge, and the pixel compensation part extends from the third sub-pixel to the concave part; the size of the fourth sub-pixel is larger than that of the third sub-pixel of the second pixel unit in the direction perpendicular to the arrangement direction of the first pixel unit, and the size of the fourth sub-pixel is smaller than that of the third sub-pixel of the second pixel unit in the arrangement direction of the first pixel unit.
Specifically, the first pixel unit arrangement direction may be parallel to the row direction, and may also be parallel to the column direction. When the first pixel unit arrangement direction is parallel to the row direction, in each pixel unit, the first sub-pixel and the second sub-pixel are positioned in one column, and the third sub-pixel is positioned in another column adjacent to the first sub-pixel; when the first pixel unit arrangement direction is parallel to the column direction, in each pixel unit, the first sub-pixel and the second sub-pixel are positioned in one row, and the third sub-pixel is positioned in another row adjacent to the first sub-pixel. That is, the first sub-pixel, the second sub-pixel and the third sub-pixel of each pixel unit in the present embodiment are arranged in a delta shape.
Exemplarily, in an embodiment of the present invention, fig. 2 is a schematic diagram of a pixel structure provided in the embodiment of the present invention. As shown in fig. 2, the plurality of pixel units 100 includes a first pixel unit 110 located at least one side edge of the pixel structure, and a second pixel unit 120 located away from at least one side edge, the first pixel unit being arranged in a direction parallel to the row direction X; the first pixel unit 110 includes a first sub-pixel 111, a second sub-pixel 112, a third sub-pixel 113, and a pixel compensation part 114 connected to the third sub-pixel 113 and emitting light of the same color, the third sub-pixel 113 and the connected pixel compensation part 114 constitute a fourth sub-pixel 115, the first sub-pixel 111 and the second sub-pixel 112 are located in one column, and the third sub-pixel 113 is located in another column adjacent to the first sub-pixel 111; the second pixel unit 120 includes a first sub-pixel 121, a second sub-pixel 122, and a third sub-pixel 123, where the first sub-pixel 121 and the second sub-pixel 122 are located in one column, and the third sub-pixel 123 is located in another column adjacent to the first sub-pixel 121; in each first pixel unit 110, the first sub-pixel 111 or the second sub-pixel 112 protrudes outward relative to the third sub-pixel 113 to form a recess 20 at least one side edge, and the pixel compensation part 114 extends from the third sub-pixel 113 into the recess 20; the size of the fourth sub-pixel 115 is larger than the size of the third sub-pixel 123 of the second pixel unit 120 in the column direction Y, and the size of the fourth sub-pixel 115 is smaller than the size of the third sub-pixel 123 of the second pixel unit 120 in the row direction X.
In this embodiment, the arrangement direction of the first pixel units is parallel to the row direction X, and the first pixel units 110 may be located in the first row and/or the last row of the pixel structure. Referring to fig. 2, when the first pixel unit 110 is located in the first row of the pixel structure, the first sub-pixel 111 protrudes outward relative to the third sub-pixel 113; when the first pixel unit 110 is located in the last first row of the pixel structure, the second sub-pixel 112 protrudes outward relative to the third sub-pixel 113. The embodiment extends from the third sub-pixel 113 to the concave portion 20 by providing the pixel compensation portion 114, and the size of the fourth sub-pixel 115 is larger than the size of the third sub-pixel 123 of the second pixel unit 120 in the column direction Y, that is, compared with the prior art, the embodiment relatively reduces the degree of outward protrusion of the first sub-pixel 111 or the second sub-pixel 112 relative to the third sub-pixel 113 by stretching the third sub-pixel 123 in the column direction Y toward the protruding direction of the first sub-pixel 111 or the second sub-pixel 112 (the stretched part is the pixel compensation portion), so that the outer contour of the pixel structure at the first pixel unit 110 is inclined to be linear from the convex-concave shape, and the light emission amount of the protruding part of the first sub-pixel 111 or the second sub-pixel 112 is reduced, thereby improving the color fringing problem of the upper edge and/or the lower edge of the display area, that is, improving the color fringing problem of the display area of the display panel, the display effect of the display panel is improved. Meanwhile, in the row direction X, the size of the fourth sub-pixel 115 is smaller than the size of the third sub-pixel 123 of the second pixel unit 120, so that the pixel area or the aperture ratio of the formed fourth sub-pixel 115 is not significantly increased, and thus, under the condition that the pixel driving signal is not changed, the brightness of the fourth sub-pixel 115 is basically unchanged, thereby avoiding the adjustment of the driving signal of the fourth sub-pixel 115 and facilitating the driving design.
In another embodiment of the present invention, fig. 3 is a schematic view of another pixel structure provided in the embodiment of the present invention. As shown in fig. 3, the pixel units 100 include a first pixel unit 110 located at least one side edge of the pixel structure, and a second pixel unit 120 located away from at least one side edge, wherein the arrangement direction of the first pixel units is parallel to the column direction Y; the first pixel unit 110 includes a first sub-pixel 111, a second sub-pixel 112, a third sub-pixel 113, and a pixel compensation part 114 connected to the third sub-pixel 113 and emitting light of the same color, the third sub-pixel 113 and the connected pixel compensation part 114 constitute a fourth sub-pixel 115, the first sub-pixel 111 and the second sub-pixel 112 are located in one row, and the third sub-pixel 113 is located in another row adjacent to the first sub-pixel 111; the second pixel unit 120 includes a first subpixel 121, a second subpixel 122, and a third subpixel 123, where the first subpixel 121 and the second subpixel 122 are located in one row, and the third subpixel 123 is located in another row adjacent to the first subpixel 121; in each first pixel unit 110, the first sub-pixel 111 or the second sub-pixel 112 protrudes outward relative to the third sub-pixel 113 to form a recess 20 at least one side edge, and the pixel compensation part 114 extends from the third sub-pixel 113 into the recess 20; the size of the fourth sub-pixel 115 is larger than the size of the third sub-pixel 123 of the second pixel unit 120 in the row direction X, and the size of the fourth sub-pixel 115 is smaller than the size of the third sub-pixel 123 of the second pixel unit 120 in the column direction Y.
In this embodiment, the first pixel unit arrangement direction is parallel to the column direction Y, and the first pixel unit 110 may be located in the first column and/or the last column of the pixel structure. Referring to fig. 3, when the first pixel unit 110 is located in the first column of the pixel structure, the first sub-pixel 111 protrudes outward relative to the third sub-pixel 113; when the first pixel unit 110 is located in the last first column of the pixel structure, the second sub-pixel 112 protrudes outward relative to the third sub-pixel 113. The embodiment extends the pixel compensation portion 114 from the third sub-pixel 113 into the recess 20, and in the row direction X, the size of the fourth sub-pixel 115 is larger than the size of the third sub-pixel 123 of the second pixel unit 120, that is, compared with the prior art, the embodiment relatively reduces the degree of outward protrusion of the first sub-pixel 111 or the second sub-pixel 112 relative to the third sub-pixel 113 by stretching the third sub-pixel 123 in the row direction X toward the protruding direction of the first sub-pixel 111 or the second sub-pixel 112 (the stretched part is the pixel compensation portion), so that the outer contour of the pixel structure at the first pixel unit 110 tends to be linear from the convex and concave, and further reduces the light emission amount of the protruding part of the first sub-pixel 111 or the second sub-pixel 112, and therefore improves the color edge problem of the left edge and/or the right edge of the display area of the display panel, that is, the color edge problem of the display area of the display panel is improved, the display effect of the display panel is improved. Meanwhile, in the column direction Y, the size of the fourth sub-pixel 115 is smaller than the size of the third sub-pixel 123 of the second pixel unit 120, so that the pixel area or the aperture ratio of the formed fourth sub-pixel 115 is not significantly increased, and thus, under the condition that the pixel driving signal is not changed, the brightness of the fourth sub-pixel 115 is basically unchanged, thereby avoiding the adjustment of the driving signal of the fourth sub-pixel 115 and facilitating the driving design.
It is to be understood that the third sub-pixel 113 and the pixel compensation part 114 in the first pixel unit 110 are only convenient for description of the pixel structure, to distinguish from the existing pixel structure, and the third sub-pixel 113 and the pixel compensation part 114 are integrally formed when the pixel structure is actually prepared.
In general, the light emitting efficiency of the blue sub-pixel is low, and the pixel area of the blue sub-pixel can be increased to improve the service life of the blue sub-pixel. In the above technical solution, the third sub-pixel, the first sub-pixel and the second sub-pixel are located in different rows or different columns, so that the pixel area of the third sub-pixel can be relatively large, and therefore, the third sub-pixel can be a blue sub-pixel, and one of the first sub-pixel and the second sub-pixel is a red sub-pixel, and the other is a green sub-pixel. In addition, human eyes are sensitive to green light, and the luminance of the green sub-pixel can be set to be large, and thus, the pixel area of the first sub-pixel and the second sub-pixel can be set to be large as the green sub-pixel. Optionally, the first sub-pixel is a green sub-pixel, the second sub-pixel is a red sub-pixel, and the third sub-pixel is a blue sub-pixel.
Optionally, in the first pixel unit, a drop between the fourth sub-pixel and a side edge of the adjacent sub-pixel located on the outer contour of the pixel structure is less than or equal to 5 micrometers.
The step is a distance from the fourth sub-pixel to the sub-pixel (the first sub-pixel or the second sub-pixel of the first pixel unit) adjacent to the fourth sub-pixel, which is located at the side of the outer contour of the pixel structure. Exemplarily, fig. 4 is a schematic structural diagram of a first pixel unit according to an embodiment of the present invention. In the present embodiment, taking the first sub-pixel 111 protruding outward relative to the third sub-pixel 113 as an example, as shown in fig. 4, in the first pixel unit 110, the difference h between the fourth sub-pixel 115 and the adjacent first sub-pixel 111 located at the side of the outer contour of the pixel structure is less than or equal to 5 μm, which can ensure that the light emission amount of the protruding portion of the first sub-pixel 111 is effectively reduced, so that the color fringing problem of at least one side edge, that is, the edge color fringing problem of the display area of the display panel, is improved, and the display effect of the display panel is improved.
Preferably, the fourth sub-pixel is flush with the side of the adjacent sub-pixel located at the outer contour of the pixel structure.
Specifically, referring to fig. 2, in the first pixel unit 110, the fourth sub-pixel 115 is flush with the side edge of the adjacent first sub-pixel 111 located on the outer contour of the pixel structure, and at this time, the outer contour of the pixel structure formed by the first pixel units 110 arranged in an array is a straight line, so that the color edge problem of at least one side edge can be further improved, that is, the edge color edge problem of the display area of the display panel is improved, and the display effect of the display panel is improved.
Optionally, the aperture ratio of the fourth sub-pixel is equal to the aperture ratio of the third sub-pixel of the second pixel unit. Therefore, when the sizes of the fourth sub-pixels in the row direction and the column direction are changed, the fourth sub-pixels can be guaranteed to keep the original aperture opening ratio, namely, the aperture opening ratio of the fourth sub-pixels is kept unchanged, so that under the condition that the pixel driving signals are unchanged, the brightness of the fourth sub-pixels is unchanged, the adjustment of the driving signals of the fourth sub-pixels is avoided, and the driving design is facilitated.
Optionally, in a direction perpendicular to the arrangement direction of the first pixel units, the size of the pixel compensation portion is smaller than half of the size of a first sub-pixel or a second sub-pixel of the second pixel unit, where the first sub-pixel or the second sub-pixel corresponds to a first sub-pixel or a second sub-pixel in the first pixel unit, the first sub-pixel or the second sub-pixel protruding outward relative to a third sub-pixel.
Specifically, fig. 5 is a schematic partial structure diagram of a pixel structure according to an embodiment of the present invention. As shown in fig. 5, the first pixel unit arrangement direction is parallel to the row direction X, the first sub-pixel 111 of the first pixel unit 110 protrudes outward relative to the third sub-pixel 113, and at this time, the size h1 of the pixel compensation part 114 is smaller than half of the size h2 of the first sub-pixel 121 of the second pixel unit 120 in the column direction Y. Considering that the size of the outward protruding portion of the first sub-pixel 111 is half of the size of the first sub-pixel 111 in the column direction Y in the conventional pixel structure, setting the size h1 of the pixel compensation part 114 to be smaller than half of the size h2 of the first sub-pixel 121 of the second pixel unit 120 in the column direction Y can prevent the white light emission center of the first pixel unit 110 from being shifted too much in a direction away from the center of the display area, thereby preventing the edge display effect from being deteriorated.
Optionally, the first sub-pixel of the first pixel unit is located on a side of the second sub-pixel far from the second pixel unit, in a direction perpendicular to the arrangement direction of the first pixel unit, the size of the first sub-pixel of the first pixel unit is smaller than that of the first sub-pixel of the second pixel unit, and in the arrangement direction of the first pixel unit, the size of the first sub-pixel of the first pixel unit is larger than that of the first sub-pixel of the second pixel unit; or the second sub-pixel of the first pixel unit is located on one side of the first sub-pixel far from the second pixel unit, in the direction perpendicular to the arrangement direction of the first pixel unit, the size of the second sub-pixel of the first pixel unit is smaller than that of the second sub-pixel of the second pixel unit, and in the arrangement direction of the first pixel unit, the size of the second sub-pixel of the first pixel unit is larger than that of the second sub-pixel of the second pixel unit.
Specifically, fig. 6 is a schematic view of another pixel structure according to an embodiment of the present invention. The present embodiment is described by taking the first pixel unit arrangement direction parallel to the row direction X as an example. As shown in fig. 6, in the first row of the first pixel unit 110, the first sub-pixel 111 is located on a side of the second sub-pixel 112 away from the second pixel unit 120, in the column direction Y, the size of the first sub-pixel 111 of the first pixel unit 110 is smaller than the size of the first sub-pixel 121 of the second pixel unit 120, and in the row direction X, the size of the first sub-pixel 111 of the first pixel unit 110 is larger than the size of the first sub-pixel 121 of the second pixel unit 120. Therefore, the fourth sub-pixel 115 is stretched along the column direction Y, and the first sub-pixel 111 is compressed along the column direction Y, so that the deviation of the white light emitting center of the first pixel unit 110 to the direction far away from the center of the display area is small, the edge display effect is ensured, and the display effect of the edge of the display area is further improved. Meanwhile, in the row direction X, the size of the first sub-pixel 111 of the first pixel unit 110 is larger than the size of the first sub-pixel 121 of the second pixel unit 120, so that the pixel area or the aperture ratio of the first sub-pixel 111 is not significantly reduced, and thus, under the condition that the pixel driving signal is not changed, the luminance of the first sub-pixel 111 is basically unchanged, thereby avoiding the adjustment of the driving signal of the first sub-pixel 111, and facilitating the driving design. In addition, for the first pixel unit 110 in the first row, the second sub-pixel 112 may be compressed (not shown in the figure) along the column direction Y, that is, in the column direction Y, the size of the second sub-pixel 112 of the first pixel unit 110 is smaller than the size of the second sub-pixel 122 of the second pixel unit 120, and in the row direction X, the size of the second sub-pixel 112 of the first pixel unit 110 is larger than the size of the second sub-pixel 122 of the second pixel unit 120, so that the offset of the white light emitting center of the first pixel unit 110 to the direction far away from the center of the display area may be further reduced, the edge display effect may be further improved, and in the case that the pixel driving signal is not changed, the luminance of the second sub-pixel 112 is substantially unchanged, thereby avoiding the adjustment of the driving signal of the second sub-pixel 112, and facilitating the driving design.
In the last first row of the first pixel unit 110, the second sub-pixel 112 is located on a side of the first sub-pixel 111 away from the second pixel unit 120, in the column direction Y, the size of the second sub-pixel 112 of the first pixel unit 110 is smaller than the size of the second sub-pixel 122 of the second pixel unit 120, and in the row direction X, the size of the second sub-pixel 112 of the first pixel unit 110 is larger than the size of the second sub-pixel 122 of the second pixel unit 120. Therefore, the fourth sub-pixel 115 is stretched along the column direction Y, and the second sub-pixel 112 is compressed along the column direction Y, so that the deviation of the white light emitting center of the first pixel unit 110 to the direction far away from the center of the display area is small, the edge display effect is ensured, and the display effect of the edge of the display area is further improved. Meanwhile, in the row direction X, the size of the second sub-pixel 112 of the first pixel unit 110 is larger than the size of the second sub-pixel 122 of the second pixel unit 120, so that the pixel area or the aperture ratio of the second sub-pixel 112 is not significantly reduced, and thus, under the condition that the pixel driving signal is not changed, the brightness of the second sub-pixel 112 is basically not changed, thereby avoiding the adjustment of the driving signal of the second sub-pixel 112, and facilitating the driving design.
Optionally, the first sub-pixel of the first pixel unit is located on a side of the second sub-pixel far from the second pixel unit, and an aperture ratio of the first sub-pixel of the first pixel unit is equal to an aperture ratio of the first sub-pixel of the second pixel unit; and/or the second sub-pixel of the first pixel unit is positioned on one side of the first sub-pixel far away from the second pixel unit, and the aperture ratio of the second sub-pixel of the first pixel unit is equal to that of the second sub-pixel of the second pixel unit. Therefore, adjustment of the driving signals of the first sub-pixel and/or the second sub-pixel of the first pixel unit can be avoided, and driving design is facilitated.
Optionally, based on the above technical solution, in another embodiment of the present invention, in the first pixel unit arrangement direction, the pixel units are repeatedly arranged; in the direction perpendicular to the arrangement direction of the first pixel units, in any two adjacent pixel units, the first sub-pixel and the second sub-pixel of one pixel unit and the third sub-pixel of the other pixel unit are positioned in one row or one column, and the third sub-pixel of one pixel unit and the first sub-pixel and the second sub-pixel of the other pixel unit are positioned in one row or one column;
preferably, the pixel center of the first sub-pixel and the pixel center of the second sub-pixel of one pixel unit are on the same straight line with the pixel center of the third sub-pixel of another pixel unit; the pixel center of the third sub-pixel of one pixel unit is on the same straight line with the pixel center of the first sub-pixel and the pixel center of the second sub-pixel of the other pixel unit.

As shown in fig. 7, the pixel units 100 are repeatedly arranged in the row direction X; in the column direction Y, in any two adjacent pixel units 100, the first sub-pixel and the second sub-pixel of one pixel unit and the third sub-pixel of another pixel unit are located in one row or one column, and the third sub-pixel of one pixel unit and the first sub-pixel and the second sub-pixel of another pixel unit are located in one row or one column. Based on the pixel center of the first sub-pixel and the pixel center of the second sub-pixel of one pixel unit are on the same straight line with the pixel center of the third sub-pixel of the other pixel unit; the pixel center of the third sub-pixel of one pixel unit is on the same straight line with the pixel center of the first sub-pixel and the pixel center of the second sub-pixel of the other pixel unit. So that the pixel center (black dot in the figure) of the first sub-pixel 111 and the pixel center of the second sub-pixel 112 of the first pixel unit 110 are on the same straight line L1 with the pixel center of the third sub-pixel 123 of the second pixel unit 120; the pixel center of the third sub-pixel 113 of the first pixel unit 110 is on the same straight line L2 with the pixel center of the first sub-pixel 121 and the pixel center of the second sub-pixel 122 of the second pixel unit 120. Therefore, when the sizes of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 of the first pixel unit 110 are changed, the positions of the pixel centers of the first sub-pixel 111, the second sub-pixel 112 and the third sub-pixel 113 in the direction perpendicular to the arrangement direction of the first pixel unit are kept unchanged, so that the pixel units 110 are uniformly distributed, and the display uniformity is improved.

In the last first row of the first pixel unit 110, the first sub-pixel 111 of the first pixel unit 110 is located on one side of the second sub-pixel 112 close to the second pixel unit 120, and in the column direction Y, the distance d3 between the first sub-pixel 111 of the first pixel unit 110 and the first sub-pixel 121 of the adjacent second pixel unit 120 is equal to the distance d4 between the first sub-pixels 121 of the two adjacent second pixel units 120, so that the first pixel unit 110 and the second pixel unit 120 can be arranged more neatly, the pixel structure is arranged more compactly, the pixel unit distribution is more uniform, the pixel space utilization rate is improved, and the pixel aperture ratio is increased.
