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 serious jagging problem when displaying the diagonal stripes, and the inventors have found through careful study that the problem is caused by the fact that fig. 1 is a schematic diagram of a pixel structure of the prior art (in the drawing of the present invention, the 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.
In order to solve the technical problems, the invention provides the following solutions:
fig. 3 is a schematic diagram of a pixel structure according to an embodiment of the present invention, referring to fig. 3, the pixel structure includes a plurality of repeating units 101 repeatedly arranged along a row direction X and a column direction Y, where the repeating unit 101 includes a first sub-pixel 1011, a second sub-pixel 1012, a third sub-pixel 1013, and a fourth sub-pixel 1014, the third sub-pixel 1013 and the fourth sub-pixel 1014 are sub-pixels of the same color, the first sub-pixel 1011 and the second sub-pixel 1012 are diagonally disposed, and the third sub-pixel 1013 and the fourth sub-pixel 1014 are diagonally disposed; in the pixel structure, the first sub-pixel 1011 and the second sub-pixel 1012 are alternately arranged in a predetermined direction Z, and the third sub-pixel 1013 and the fourth sub-pixel 1014 are alternately arranged in the predetermined direction Z, which intersects with the row direction X and the column direction Y.
Specifically, the pixel structure may include three color sub-pixels, for example, 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 and the fourth sub-pixel 1014 may be green sub-pixels, and the luminance of the three color sub-pixels are matched to realize full color display. Based on the technical scheme of the embodiment, the number ratio of the red sub-pixels, the green sub-pixels and the blue sub-pixels in the pixel structure is 1. The predetermined directions Z of the first sub-pixel 1011 and the second sub-pixel 1012 are neither parallel to the row direction X nor perpendicular to the row direction X. The pixel centers of the first sub-pixel 1011, the second sub-pixel 1012, the third sub-pixel 1013, and the fourth sub-pixel 1014 may form a virtual quadrangle and are respectively located at four vertices of the virtual quadrangle, and the vertices of the virtual quadrangle where the pixel centers of the third sub-pixel 1013 and the fourth sub-pixel 1014 are located are not adjacent. When the repeating unit 101 is repeatedly arranged in the row and column directions, the first sub-pixel 1011 and the second sub-pixel 1012 are alternately arranged, and the third sub-pixel 1013 and the fourth sub-pixel 1014 are alternately arranged in the preset direction Z, and when the unit is used for oblique stripe display, the extending direction of the oblique stripes is approximately consistent with the preset direction, and no obvious saw tooth problem exists.
In the following, the diagonal stripe display is described with reference to a specific example, and fig. 4 is a schematic diagram of pixel arrangement of the diagonal stripe display area in fig. 3; in conjunction with fig. 3 and 4, the diagonal portion 102 in the pixel structure is used to display diagonal stripes, and the extending direction of the diagonal portion 102 is approximately the same as the extending direction of the diagonal stripes. When the display panel emits white light, the light emission center of the white light is closer to the green sub-pixel, that is, closer to the third sub-pixel 1013 and the fourth sub-pixel 1014. When oblique stripes are displayed, because the third sub-pixel 1013 and the fourth sub-pixel 1014 are alternately arranged in the preset direction Z, and in the oblique portion 102, the third sub-pixel 1013 and the fourth sub-pixel 1014 are both located on the same straight line parallel to the preset direction Z, the third sub-pixel 1013 or the fourth sub-pixel 1014 is not present in other areas outside the straight line, and the first sub-pixel 1011 and the second sub-pixel 1012 are also alternately arranged, and for the repeating unit shown in fig. 3, the light emitting center of the white light can be approximately located at the geometric center of the virtual quadrangle where the repeating unit 101 is located, so that the connecting line of the light emitting centers of the white lights is also approximately located on a straight line parallel to the preset direction Z (the virtual straight line 1021 in fig. 4), and the virtual straight line 1021 and the oblique stripes parallel to the preset direction Z extend smoothly in the preset direction Z, and there is no obvious jaggy problem, thereby improving the display effect.
In the technical scheme of this embodiment, the adopted pixel structure includes a repeating unit repeatedly arranged along the row direction and the column direction, the repeating unit includes a first sub-pixel, a second sub-pixel, a third sub-pixel and a fourth sub-pixel, the third sub-pixel and the fourth sub-pixel are sub-pixels with the same color, the first sub-pixel and the second sub-pixel are diagonally arranged, and the third sub-pixel and the fourth sub-pixel are diagonally arranged; in the pixel structure, the first sub-pixels and the second sub-pixels are alternately arranged in a preset direction, the third sub-pixels and the fourth sub-pixels are alternately arranged in the preset direction, and the preset direction is intersected with the row direction and the column direction. When the diagonal stripes are displayed, the first sub-pixels and the second sub-pixels are alternately arranged in the preset direction, the third sub-pixels and the fourth sub-pixels are alternately arranged in the preset direction, and the third sub-pixels and the fourth sub-pixels are diagonally arranged in combination with the diagonal arrangement of the first sub-pixels and the second sub-pixels, so that the light-emitting centers of the white light of the diagonal stripe display area tend to be on a straight line extending along the preset direction, an obvious sawtooth problem cannot be generated, and the display effect is greatly improved.
Optionally, a line connecting pixel centers of the first sub-pixel 1011 and the second sub-pixel 1012 alternately arranged in the preset direction Z is parallel to the preset direction Z, and a line connecting pixel centers of the third sub-pixel 1013 and the fourth sub-pixel 1014 alternately arranged in the preset direction Z is parallel to the preset direction Z.
Specifically, the center of a pixel can be understood as the geometric center of the pixel, for example, when the pixel is a circle, the center of the pixel is the center of the circle, and when the pixel is a rectangle, the center of the pixel is the intersection point of two diagonal lines of the rectangle; thus, a first sub-pixel, a second sub-pixel and a third sub-pixel or a fourth sub-pixel can form a pixel unit emitting white light. Since the light emitting center of the white light cannot be completely located on the third sub-pixel, the centers of the first sub-pixel and the second sub-pixel are arranged on a straight line parallel to the preset direction Z; and the third sub-pixel and the fourth sub-pixel are also arranged on a straight line parallel to the preset direction Z, so that the connecting line of the white light centers of the equivalent multiple pixel units is basically located on a straight line parallel to the preset direction Z, the problem of saw teeth when oblique stripes are displayed is further avoided, and the display effect is further improved.
Optionally, the preset direction Z includes a first preset direction Z1 and a second preset direction Z2 which intersect with each other, preferably, the first preset direction Z1 has a first included angle smaller than 90 degrees with the row direction X, and the second preset direction Z2 has a second included angle smaller than 90 degrees with the row direction; the first included angle is equal to the second included angle, and/or the first preset direction Z1 is vertically intersected with the second preset direction Z2.
Specifically, the oblique stripes that the display panel needs to display are not only of a type extending in one direction, for example, when displaying a chinese character "wood", but also of a type extending in a left lower direction and a right lower direction, and by setting two preset directions, namely, the first preset direction Z1 and the second preset direction Z2, when displaying the oblique stripes, the oblique stripes extending in the first preset direction Z1 and the second preset direction Z2 do not have the problem of saw teeth, thereby further improving the display effect. And the first preset direction Z1 and the second preset direction Z2 are vertically intersected, so that the right-angle edge display of the inclined graph is facilitated.
Preferably, the first included angle and the second included angle are both 45 degrees.
Specifically, first contained angle and second contained angle set up to equal, if all set up to 45 degrees, when showing chinese character, the oblique stripe in the chinese character is generally by the oblique stripe or the combination of a plurality of this oblique stripe that extend along the direction that is 45 degrees with the line direction and forms, sets up like this, can make display panel have more smooth display effect when showing chinese character, the very big sawtooth problem that exists when having avoided showing chinese character. In addition, when the display panel is a special-shaped screen, for example, when the display panel is a display panel with a chamfer, the scheme provided by the embodiment of the invention can better display oblique stripes without the problem of saw teeth, so that the display transition of each part at the chamfer is smooth without the problem of saw teeth, and the display effect of the display panel is improved when the chamfer exists.
Optionally, with continued reference to fig. 4, each of the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel includes at least one oblique side parallel to the preset direction.
Specifically, as shown in fig. 3, the first sub-pixel may include a first oblique side 1111, the second sub-pixel may include a second oblique side 1112, the third sub-pixel may include a third oblique side 1113, the fourth sub-pixel may include a fourth oblique side 1114, the first oblique side 1111, the second oblique side 1112, the third oblique side 1113 and the fourth oblique side 1114 may all be parallel to the predetermined direction Z, for example, when the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel are all rectangular, the first oblique side 1111 is located at the lower left side of the first sub-pixel, the second oblique side 1112 is located at the lower left side of the second sub-pixel, when displaying an oblique stripe, the first oblique side 1111 and the second oblique side 1112 are edges of the oblique stripe, if at least one of the first oblique side 1111 and the second oblique side 1112 is not parallel to the predetermined direction, the edge of the oblique stripe may generate a sawtooth problem when displaying, the sawtooth problem may be present at an edge of the oblique stripe, and the influence on the display effect may be slightly less when the light emission center of the oblique stripe extends in the direction, that the display may be less than the case of a display stripe extending in the case of a tooth-bar extending direction, i.e. Through setting up first hypotenuse 1111 and second hypotenuse 1112 and all being on a parallel with the direction of predetermineeing, when showing oblique stripe, the edge of oblique stripe is approximately for being on a parallel with the straight line of the direction of predetermineeing, and the transitivity at oblique stripe edge is better, can not present serious cockscomb structure to very big improvement the display effect of edge when showing oblique stripe. It should be noted that, in some cases, the third sub-pixel and the fourth sub-pixel may be used as edges of the oblique stripes, and by setting the third oblique edge 1113 and the fourth oblique edge 1114 to be also parallel to the preset direction, when the oblique stripes are displayed, the edges of the oblique stripes are similar to a straight line parallel to the preset direction, and the edges have a better transitivity and do not present a severe saw-tooth shape, so that the display effect when the edges of the oblique stripes are displayed is greatly improved.
Preferably, the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel each include two opposite sides parallel to the first preset direction; and/or the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel respectively comprise two opposite edges which are parallel to the second preset direction.
Illustratively, in the case of displaying the chinese character "wood", the sub-pixel (the first sub-pixel, the second sub-pixel, the third sub-pixel, or the fourth sub-pixel) may be a left edge of a diagonal stripe extending downward to the left, and may also be a right edge of a diagonal stripe extending downward to the left; similarly, it is also possible to use the left edge of the diagonal stripe extending downward to the right, and it is also possible to use the right edge of the diagonal stripe extending downward to the right; each sub-pixel is arranged to comprise two opposite sides parallel to a first preset direction, and two opposite sides parallel to a second preset direction, and no matter the sub-pixel is used as a first edge (such as a left edge) of a diagonal stripe extending along the first preset direction, as a second edge (such as a right edge) of the diagonal stripe extending along the first preset direction, as a first edge of the diagonal stripe extending along the second preset direction, or as a second edge of the diagonal stripe extending along the second preset direction, the edge of the diagonal stripe can be similar to a straight line parallel to the preset direction, the transitivity of the edge is better, serious saw-toothed shape cannot be presented, and therefore the display effect when the edge of the diagonal stripe is displayed is further improved.
Optionally, with reference to fig. 3, in the first sub-pixel and the second sub-pixel where the connection line of the pixel center is parallel to the preset direction, the sides parallel to the connection line of the pixel center and located on the same side of the connection line of the pixel center are located on the same straight line.
Specifically, as shown in fig. 3, the first oblique side 1111 and the second oblique side 1112 are located on the same straight line, and the straight line is parallel to the preset direction, when displaying the oblique stripe extending along the preset direction, because the first oblique side 1111 and the second oblique side 1112 are used as the edge of the oblique stripe, that is, the edge of the oblique stripe will be located on the same straight line parallel to the preset direction, that is, the edge transition of the oblique stripe will be smoother, and there is substantially no problem of saw teeth, thereby further improving the display effect when displaying the edge of the oblique stripe.
Optionally, with continued reference to fig. 2, the first pixel 1011 and the second subpixel 1012 are diamond-shaped.
Specifically, the first subpixel 1011 and the second subpixel 1012 are set to be diamond-shaped, so that two sides parallel to the first preset direction and two sides parallel to the second preset direction of the first subpixel 1011 and the second subpixel 1012 can be guaranteed, and it is guaranteed that no sawtooth problem exists at the edge of the oblique stripe when the oblique stripe is displayed, and no redundant side exists at the first subpixel 1011 and the second subpixel 1012, that is, when the oblique stripe is displayed, the redundant side does not influence the edge of the oblique stripe, so that the display effect when the oblique stripe is displayed is further improved under the condition that the shape of the pixel is simple.
Alternatively, the third and fourth sub-pixels 1013 and 1014 are rectangular.
By arranging the third sub-pixel 1013 and the fourth sub-pixel 1014 in a rectangular shape, the utilization rate of the display panel can be improved, for example, the first sub-pixel 1011, the second sub-pixel 1012, the third sub-pixel 1013, and the fourth sub-pixel 1014 can be arranged more compactly, and the third sub-pixel 1013 and the fourth sub-pixel 1014 can be arranged by sufficiently utilizing the gap between the first sub-pixel 1011 and the second sub-pixel 1012, thereby improving the pixel density of the display panel.
Preferably, two opposite long sides of the third sub-pixel 1013 are parallel to the first preset direction, and two opposite short sides of the fourth sub-pixel are parallel to the first preset direction. The arrangement of the first sub-pixel 1011, the second sub-pixel 1012, the third sub-pixel 1013, and the fourth sub-pixel 1014 is more compact, for example, for the sub-pixels in the repeating unit 101, when the total area occupied by the repeating unit 101 is constant, the areas of the third sub-pixel 1013 and the fourth sub-pixel 1014 can be ensured to be larger, and since the third sub-pixel 1013 and the fourth sub-pixel 1014 are green sub-pixels, the display effect of the green sub-pixel has a larger influence on the human eye, that is, while the high pixel density can be ensured, the higher display effect can be ensured.
Optionally, in each repeating unit, a distance between pixel centers of the first sub-pixel and the second sub-pixel is h1, and a distance between centers of the third sub-pixel and the fourth sub-pixel is h2, wherein h1= h2.
By the arrangement, the sub-pixels can be reasonably arranged, and the pixel space utilization rate is improved, so that the pixel density is further improved, and high-resolution display is facilitated.
Optionally, in the same row of sub-pixels of the pixel structure, the pixel centers of the sub-pixels are located on the same straight line; and/or the pixel centers of the sub-pixels are positioned on the same straight line in the same column of the sub-pixels in the pixel structure.
Exemplarily, as shown in fig. 3, in the first row of sub-pixels (the uppermost row of sub-pixels is shown), the pixel centers of each second sub-pixel 1012 and each third sub-pixel 1013 are located on the same straight line, so as to avoid the problem of color shift of the upper edge caused by the large degree of outward protrusion of the endmost second sub-pixel 1012 or third sub-pixel 1013; similarly, in the first column of sub-pixels (the leftmost row of sub-pixels is shown), the centers of the second sub-pixels 1012 and the fourth sub-pixels 1014 are located on the same straight line, so that the problem of color shift of the left edge due to the large degree of outward protrusion of the second sub-pixel 1012 or the fourth sub-pixel 1014 at the outermost edge is avoided. Therefore, in the present embodiment, by setting the sub-pixels in the same row of the pixel structure, the pixel centers of the sub-pixels are located on the same straight line; and/or in the same column of sub-pixels of the pixel structure, the pixel centers of the sub-pixels are positioned on the same straight line, so that the edge color cast phenomenon of the display panel is improved, and the display effect is further improved.
Preferably, in the same row of sub-pixels of the pixel structure, the pixel centers of the sub-pixels are arranged at equal intervals; and/or the pixel centers of the sub-pixels are arranged at equal intervals in the same column of the sub-pixels in the pixel structure.
With this arrangement, in the pixel structure, the arrangement between the sub-pixels and between the repeating units is more compact, so that the pixel density of the display panel can be further improved.
It should be noted that, in the pixel structure of this embodiment, pixel sharing may be further used to improve the pixel density of the display panel, for example, when the first sub-pixel 1011 is a red sub-pixel, the second sub-pixel 1012 is a blue sub-pixel, and the third sub-pixel 1013 and the fourth sub-pixel 1014 are green sub-pixels, based on the above technical solution of this embodiment, the number ratio of the red sub-pixel, the green sub-pixel and the blue sub-pixel in the pixel structure is 1. As for the pixel structure in fig. 3, the first sub-pixel 1011 may be shared by two adjacent fourth sub-pixels 1014 of the same row located at two sides of the first sub-pixel 1011, and the second sub-pixel 1012 may be shared by two adjacent third sub-pixels 1013 of the same row located at two sides of the second sub-pixel 1012, so that the first sub-pixel 1011 and the second sub-pixel 1012 are shared twice respectively, thereby greatly increasing the pixel density of the display panel and further improving the display effect. In addition, fig. 3 only exemplarily shows a practicable pixel structure, and the pitch of the pixel centers of two adjacent third sub-pixels 1013 (or fourth sub-pixels 1014) in the same row in fig. 3 is equal to the pitch of the pixel centers of two adjacent third sub-pixels 1013 (or fourth sub-pixels 1014) in the same column. In other embodiments of the present invention, the pitch of the pixel centers of two adjacent third sub-pixels 1013 (or fourth sub-pixels 1014) in the same row may be twice the pitch of the pixel centers of two adjacent third sub-pixels 1013 (or fourth sub-pixels 1014) in the same column, so as to better match the design of the pixel resolution.
