Detailed Description
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 art, the conventional display panel has a problem of jagging when the oblique stripes are displayed, a problem of jagging at the chamfered portions, and a problem of color fringes at the edges of the display area. The inventor has found through careful study that the above technical problem is caused because fig. 1 is a schematic diagram of a pixel structure of the prior art (in the drawings of the present invention, sub-pixels with the same filling represent sub-pixels of the same color); FIG. 2 is a schematic diagram of a pixel layout of the slanted stripe display area of FIG. 1. As shown in fig. 1 and fig. 2, in the pixel structure, the red sub-pixel 1011 ', the blue sub-pixel 1012 ' and the green sub-pixel 1013 ' are arranged in a delta shape as a whole, and fig. 1 exemplarily shows a diagonal stripe display region 101 ', since human eyes are sensitive to green light, when white light is displayed, the light emitting center of the white light is closer to the green sub-pixel 1013 ', when diagonal stripes are displayed, as is apparent from fig. 2, in the extending direction of the diagonal stripes, the connecting lines of the pixel centers of the plurality of green sub-pixels 1013 ' are not on a straight line and are in an obvious step shape, and therefore, the connecting lines of the light emitting center of the white light in the extending direction of the diagonal stripes of the diagonal stripe display region 101 ' are also in an obvious step shape, resulting in that the displayed diagonal stripes have an obvious jagged feeling; meanwhile, for the edge of the diagonal stripe, the diagonal stripe may also have a jaggy feeling due to the extension direction of the side of the sub-pixel, e.g., the blue sub-pixel 1012', not being identical to the extension direction of the diagonal stripe. Furthermore, with continued reference to fig. 1, since the first row of blue sub-pixels 1012 'is shown to be relatively convex and the last row of green sub-pixels 1013' is shown to be relatively convex, the upper edge of the display area presents a blue edge and the lower edge presents a green edge, and the problem of color fringing at the edge of the display area arises. In addition, fig. 3 is a schematic diagram of pixel arrangement at a conventional corner, taking the pixel structure shown in fig. 1 as an example, as shown in fig. 3, due to the structural design of the radian at the corner, the pixels at the corner are not regularly distributed as on a rectangular display panel, and the pixels at the corner are distributed in a step-like manner, so that a sawtooth feeling is brought to an observer at the corner when the display panel displays.
Aiming at the technical problem, the invention provides a technical scheme that sub-pixels are obliquely arranged, so that each sub-pixel positioned at the round corner of a display panel can be matched with a round corner design, the smooth transition of the edge of each sub-pixel at the round corner is realized, and the sawtooth problem at the round corner is further improved; meanwhile, due to the inclined arrangement of the first sub-pixel and the second sub-pixel, the projection degree of the edge sub-pixel is reduced, and the color edge problem of the edge of the display area is improved. In addition, the invention also provides another technical scheme, the pixel centers of four adjacent sub-pixels with the same color are respectively arranged at four vertexes of the virtual parallelogram, and the diagonals corresponding to the virtual parallelogram are parallel, so that when oblique stripes are displayed, the light-emitting center of the white light in the oblique stripe display area is positioned on the same straight line parallel to the diagonals, the obvious sawtooth problem can not be generated, and the display effect is improved.
Specifically, in an embodiment of the present invention, fig. 4 is a schematic diagram of a pixel structure provided in an embodiment of the present invention, and as shown in fig. 4, the pixel structure provided in this embodiment includes a plurality of pixel units 101 repeatedly arranged, where each pixel unit includes a first sub-pixel 1011, a second sub-pixel 1012, and a third sub-pixel 1013 with different colors;
the first sub-pixel 1011 and the second sub-pixel 1012 are both in a stripe shape, the length direction of the first sub-pixel 1011 is a first direction X ', the length direction of the second sub-pixel 1012 is a second direction Y', the first direction X 'is different from the second direction Y' (or the first direction X 'is intersected with the second direction Y'), and the first direction X 'and the second direction Y' are intersected with the row direction X and the column direction Y;
wherein, along the first direction X ', the third sub-pixel 1013 overlaps the second sub-pixel 1012, and along the second direction Y', the third sub-pixel 1013 overlaps the first sub-pixel 1011, i.e. the first sub-pixel 1011 and the second sub-pixel 1012 are disposed half-way around the third sub-pixel 1013.
It will be understood that, when two structures overlap in a certain direction, a part of one structure may coincide with an orthographic projection of a part of the other structure in the certain direction, or the orthographic projection of one structure in the certain direction may be completely located within the orthographic projection of the other structure in the certain direction. The row direction X and the column direction Y should be row and column directions in the sense that the display screen is conventionally placed in a landscape or portrait screen. The specific arrangement of the first sub-pixel 1011, the second sub-pixel 1012 and the third sub-pixel 1013 on the display panel is not limited by the embodiment of the present invention, and when the pixel structure of the present invention is applied to the display panel, the arrangement of the first sub-pixel 1011, the second sub-pixel 1012 and the third sub-pixel 1013 may be determined according to the position of the rounded corner of the display panel, for example, in fig. 4, the first sub-pixel 1011 and/or the second sub-pixel 1012 may be disposed close to the rounded corner. Fig. 4 only exemplarily shows one possible pixel structure, and the embodiment of the present invention is only illustrated by taking the pixel structure shown in fig. 4 as an example, and is not limited to the pixel structure.
Specifically, the first sub-pixel 1011 may be a red sub-pixel, the second sub-pixel 1012 may be a blue sub-pixel, and the third sub-pixel 1013 may be a green sub-pixel; the first subpixel 1011 and the second subpixel 1012 are both stripe-shaped. By setting the length direction of the first sub-pixel 1011 to be the first direction X ', the length direction of the second sub-pixel 1012 to be the second direction Y', the first direction X 'is different from the second direction Y', and the first direction X 'and the second direction Y' are both intersected with the row direction X and the column direction Y, an included angle between the oblique direction of the first sub-pixel 1011 and the second sub-pixel 1012 and the row direction X is greater than 0 degree and less than 90 degrees. Referring to fig. 5, since the first sub-pixel and the second sub-pixel are both disposed in an inclined manner with respect to the row direction X and the column direction Y, each sub-pixel located at a corner of the display panel can be more matched with a fillet design, that is, the inclination of the first sub-pixel and the second sub-pixel is matched with the radian of the fillet, thereby realizing smooth transition of each sub-pixel edge at the fillet and further improving the problem of saw teeth at the corner. In this embodiment, the fillet may be located at the chamfer of the display panel with the chamfer design, may also be located at the "bang" of the bang screen, and may also be located at the blind hole (the area for disposing the photosensitive element) of the transparent display panel. In addition, referring to fig. 4, due to the oblique arrangement of the first sub-pixel 1011 and the second sub-pixel 1012, the protrusion degree of the edge sub-pixel is reduced, thereby improving the color fringe problem at the edge of the display area. For example, the first row of sub-pixels is the first sub-pixel 1011, and the area of the first sub-pixel 1011 protruding outward is reduced compared with the existing vertically arranged sub-pixels, so that the light emission amount of the protruding portion of the first sub-pixel 1011 is reduced, that is, the luminance of the light emitted from the corresponding area is reduced, and the problem of color fringe at the edge of the display area is improved.
Therefore, the pixel structure provided by the embodiment can improve the sawtooth problem at the round corner of the display panel and the color edge problem at the edge of the display area.
Optionally, the third sub-pixel comprises a first side far away from the first sub-pixel and a second side far away from the second sub-pixel, the first side is parallel to the first direction, and the second side is parallel to the second direction; wherein the third sub-pixel may be a parallelogram to facilitate the preparation of the mask opening. Therefore, no matter the first sub-pixel, the second sub-pixel or the third sub-pixel is arranged close to the round corner, the edge pixel unit can be well matched with the round corner, the problem of saw teeth at the round corner is further solved, and the flexibility of sub-pixel arrangement is improved.
Based on the above technical solution, in another embodiment of the present invention, with continuing reference to fig. 4, in this embodiment, by setting the pixel centers of four adjacent first sub-pixels 1011 to be located at four vertices of the first virtual parallelogram 201, the pixel centers of four adjacent second sub-pixels 1012 to be located at four vertices of the second virtual parallelogram 301, and the pixel centers of four adjacent third sub-pixels 1013 to be located at four vertices of the third virtual parallelogram 401, the first virtual parallelogram 201, the second virtual parallelogram 301, and the third virtual parallelogram 401 each include a first diagonal line parallel to each other and a second diagonal line parallel to each other. Referring to fig. 6, the pixel centers of the first subpixel 1011, the second subpixel 1012, and the third subpixel 1013 of each pixel unit 101 form a triangle (a dashed triangle frame in fig. 6) such that the light emission center of the white light of the pixel unit 101 is located at the geometric center of the triangle (a black circle point in fig. 6). Since the first virtual parallelogram 201, the second virtual parallelogram 301 and the third virtual parallelogram 401 all include the first diagonal line and the second diagonal line which are parallel to each other, when displaying the diagonal stripe whose oblique direction is parallel to the extending direction Z of the first diagonal line or the second diagonal line, the light emitting centers of the white light of each pixel unit 101 in the diagonal stripe display area are necessarily located on the same straight line, and the extending direction of the straight line is parallel to the extending direction Z of the diagonal line, thereby weakening the saw tooth feeling of the diagonal stripe and improving the display effect of the diagonal stripe. In addition, through the pixel arrangement, the light emitting centers of the white light of the pixel units in the same row or the same column at the edge of the display area can be positioned on the same straight line, so that the problem of color edge at the edge of the display area is further improved.
Therefore, the pixel structure provided by the embodiment can improve the display effect of the oblique stripes.
Preferably, the second direction Y' is parallel to the first diagonal line or the second diagonal line, and thus, the second sub-pixel 1012 is inclined along the extending direction of the first diagonal line or the second diagonal line, so that the side of the diagonal stripe display area is relatively flat, and the sawtooth problem of diagonal stripe display is further improved. Exemplarily, referring to fig. 7, by disposing the long side of the second sub-pixel 1012 in parallel with the diagonal line (the diagonal extension direction Z), the edge of the diagonal stripe on the side of the second sub-pixel 1012 is made flat, thereby further improving the saw tooth problem of the diagonal stripe display. In a preferred embodiment of the present invention, with reference to fig. 7, the short side of the first sub-pixel 1011 is parallel to the diagonal line (the diagonal extension direction Z), the third sub-pixel 1013 has a third side far from the second sub-pixel 1012, and the third side is parallel to the diagonal line (the diagonal extension direction Z), so that the edge of the diagonal stripe at the opposite side of the second sub-pixel 1012 is flat, thereby further improving the sawtooth problem of the diagonal stripe display.
Furthermore, the included angle between the second direction Y' and the row direction X is 45 degrees, so that the display effect of the Chinese characters is improved. When showing chinese character, the oblique stripe in the chinese character is generally formed by oblique stripe or the combination of a plurality of this oblique stripes that the direction that is 45 degrees extends along with the line direction, and the contained angle between long limit and the line direction through setting up the second sub-pixel is 45 degrees, can make display panel have more smooth display effect when showing chinese character, very big sawtooth problem that exists when having avoided showing chinese character. Illustratively, when the Chinese character "wood" is displayed, because the included angle between the oblique stripes corresponding to the left falling and the right falling of the "wood" and the row direction is close to 45 degrees, the left falling and the right falling saw tooth feeling of the "wood" can be reduced by setting the included angle between the long side of the second sub-pixel and the row direction to be 45 degrees, and the display effect of the "wood" is improved.
In addition, based on the pixel structure shown in fig. 1, referring to fig. 8, in any column of pixel units, the pixel center of the green sub-pixel 1013 'is a wavy line along the connection line in the column direction, and since human eyes are sensitive to green light, the light emitting center of white light of each pixel unit is close to the green sub-pixel 1013', so that the light emitting center of white light in one column of pixel units is a wavy line along the connection line in the column direction, and further, the display of vertical stripes has a sawtooth problem.
In view of the above technical problem, in another embodiment of the present invention, the first virtual parallelogram is a rectangle, and one side of the rectangle is parallel to the row direction. Therefore, the first virtual parallelogram, the second virtual parallelogram and the third virtual parallelogram are all rectangles, one side of each rectangle is parallel to the row direction, the other adjacent side is parallel to the column direction, so that in any row of pixel units, the connecting line of the pixel centers of each first sub-pixel forms a straight line which is parallel to the row direction, the connecting line of the pixel centers of each second sub-pixel forms a straight line which is parallel to the row direction, and the connecting line of the pixel centers of each third sub-pixel forms a straight line which is parallel to the row direction; in any row of pixel units, the connecting lines of the pixel centers of the first sub-pixels form a straight line which is parallel to the row direction, the connecting lines of the pixel centers of the second sub-pixels form a straight line which is parallel to the row direction, and the connecting lines of the pixel centers of the third sub-pixels form a straight line which is parallel to the row direction and the column direction. Therefore, by setting the first virtual parallelogram to be a rectangle, one side of the rectangle is parallel to the row direction, and the sawtooth problem displayed by the horizontal stripes and the vertical stripes can be improved. Exemplarily, referring to fig. 9, in any column of pixel units, the first sub-pixel is a red sub-pixel, the second sub-pixel is a blue sub-pixel, and the third sub-pixel 1013 is a green sub-pixel, by the above arrangement, the connection line of the pixel centers of the third sub-pixel 1013 forms a straight line, and the straight line is parallel to the column direction, so that the sawtooth problem of vertical stripe display can be improved.
Preferably, the first virtual parallelogram is a square. Therefore, based on the technical scheme, the first virtual parallelogram is set to be square, the problem of sawtooth displayed by the horizontal stripes and the vertical stripes is improved, meanwhile, the pixel arrangement is more compact, and the space utilization rate is improved and the pixel aperture opening ratio is increased.
Optionally, the first sub-pixel and the third sub-pixel are far away from the second sub-pixel, and the sides parallel to the second direction are flush. With continued reference to fig. 4 and 7, by disposing the first sub-pixel 1011 and the third sub-pixel 1013 away from the second sub-pixel 1012 and aligning the sides parallel to the second direction, the flatness of the sides corresponding to the diagonal stripes can be improved when the diagonal stripes are displayed, so that the jaggy feeling of the diagonal stripes is reduced and the jaggy problem of the diagonal stripe display is improved. Preferably, along the second direction Y', the second sub-pixel 1012 overlaps the first sub-pixel 1011, so that the arrangement of the first sub-pixel 1011, the second sub-pixel 1012 and the third sub-pixel 1013 is more compact, which is beneficial to improving the space utilization rate and increasing the pixel aperture ratio.
Further, referring to fig. 10 and 11, the first subpixel 1011 and the second subpixel 1012 are far from the third subpixel 1013 and are flush with each other at the side parallel to the second direction. According to the technical scheme, the flatness of two side edges of the oblique stripes can be improved when the oblique stripes are displayed, so that the sawtooth feeling of the oblique stripes is further weakened, and the sawtooth problem of oblique stripe display is improved.
Optionally, an angle between the long side of the first sub-pixel and the row direction is less than or equal to 45 degrees, for example, an angle between the long side of the first sub-pixel and the row direction is equal to 30 degrees. Preferably, the second direction is perpendicular to the first direction. From this, to the condition of display panel top fillet, the contained angle between long limit through setting up first sub-pixel and the line direction is less, more is favorable to the smooth transition of first sub-pixel in fillet department, improves the sawtooth problem that fillet department shows.
Optionally, two pixel units adjacent in the column direction include a first pixel unit and a second pixel unit, and along the first direction, a first sub-pixel of the second pixel unit overlaps with a second sub-pixel of the first pixel unit; an orthogonal coordinate system is established by taking the pixel center of the first sub-pixel as an origin, the X axis of the orthogonal coordinate system is parallel to the row direction, the Y axis of the orthogonal coordinate system is parallel to the row direction, and a straight line which passes through the origin and is parallel to the first direction extends in one quadrant and three quadrants of the orthogonal coordinate system. Illustratively, with continued reference to fig. 10, two pixel units adjacent in the column direction Y include a first pixel unit 102 and a second pixel unit 103, and along the first direction X', a first sub-pixel 1011 of the second pixel unit 103 overlaps a second sub-pixel 1012 of the first pixel unit 102. Therefore, two adjacent pixel units in the column direction Y are arranged more compactly, and the space utilization rate and the pixel aperture ratio can be improved.
Preferably, the first sub-pixel 1011 of the second pixel unit 103 is far away from the first pixel unit 102 and parallel to the side of the first direction, and is flush with the second sub-pixel 1012 of the first pixel unit 102 and far away from the first sub-pixel 1011 of the first pixel unit 102 and parallel to the side of the first direction, so that the space utilization rate can be further improved and the pixel aperture ratio can be further increased.
Further, two pixel units adjacent to each other in the row direction X include the first pixel unit 102 and the third pixel unit 104, and the second sub-pixel 1012 and the third sub-pixel 1013 of the first pixel unit 102 are close to the first sub-pixel 1011 and are parallel to the side of the first direction, and are flush with the side of the first sub-pixel 1011 of the third pixel unit 104 which is far from the third sub-pixel 1013 and is parallel to the first direction. Therefore, the second sub-pixel 1012 and the third sub-pixel 1013 in each pixel unit are closely arranged with the first sub-pixel 1011, so that the pixel arrangement is more compact, which is beneficial to improving the space utilization rate and increasing the pixel aperture ratio.
Alternatively, the distance between the pixel centers of two second sub-pixels adjacent in the row direction is equal to the distance between the pixel centers of two first sub-pixels adjacent in the column direction. Therefore, the pixel arrangement is more compact, and the space utilization rate and the pixel aperture opening ratio are improved. Preferably, the pixel center of the third sub-pixel is on the same straight line with the pixel centers of two second sub-pixels adjacent to each other in the row direction, and the pixel center of the third sub-pixel is on the same straight line with the pixel centers of two first sub-pixels adjacent to each other in the column direction, so that the space utilization rate can be further improved, and the pixel aperture ratio can be increased.
Exemplarily, referring to fig. 12, by setting a distance h1 between pixel centers of two second subpixels 1012 adjacent in the row direction to be equal to a distance h2 between pixel centers of two first subpixels 1011 adjacent in the column direction, a pixel center of a third subpixel 1013 is on the same straight line as pixel centers of two second subpixels 1012 adjacent in the row direction, and a pixel center of the third subpixel 1013 is on the same straight line as pixel centers of two first subpixels 1011 adjacent in the column direction, it is possible to make the pixel centers of two first subpixels 1011 and two second subpixels 1012 surrounding one third subpixel 1013 respectively located at midpoints of four sides of one virtual square 601, and the pixel center of one third subpixel 1013 surrounded is located at the center of the virtual square 301. Therefore, the pixel arrangement is more compact, and the space utilization rate and the pixel aperture opening ratio are improved.
