Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.
An embodiment of the present application provides a pixel arrangement structure, as shown in fig. 1 and 2, fig. 1 and 2 are schematic arrangement diagrams of the pixel arrangement structure, and the pixel arrangement structure includes:
a plurality of pixel units 10, each pixel unit 10 comprising four first sub-pixels 11, two second sub-pixels 12 and two third sub-pixels 13.
The geometric centers of the four first sub-pixels 11 are used as four vertexes of a parallelogram, the geometric centers of the two second sub-pixels 12 and the geometric centers of the two third sub-pixels 13 form a rectangle, the second sub-pixels 12 are arranged inside the parallelogram, the first sub-pixels 11 are arranged inside the rectangle, the two second sub-pixels 12 are located at two ends of one diagonal of the rectangle, and the two third sub-pixels 13 are located at two ends of the other diagonal of the rectangle.
The extending directions of the two second sub-pixels 12 intersect, and the extending directions of the two third sub-pixels 13 intersect.
The plurality of pixel units 10 are arranged such that the geometric centers of the first sub-pixels 11 in the same row are on the same horizontal straight line, and the geometric centers of the first sub-pixels 11 in the alternate rows are on the same vertical straight line.
Or
The plurality of pixel units 10 are arranged such that the geometric centers of the first sub-pixels 11 of the same column are on the same vertical straight line, and the geometric centers of the first sub-pixels 11 of the alternate columns are on the same horizontal straight line.
In fig. 1 and fig. 2, each of the row and column directions includes three pixel units 10 arranged in sequence, and it is understood that in the practical application process, more pixel units 10 are arranged on the same row or column, and the arrangement shown in fig. 1 and 2 is only for making the present solution clearer, and does not make a specific limitation on the pixel arrangement structure provided in the embodiment of the present application. Still referring to fig. 1 and 2, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 shown in fig. 1 and 2 are all rectangular in top view, and in practical applications, the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 may also be other shapes (e.g., parallelogram, ellipse, etc.) with a longer length in a certain direction. When the top view shape of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is a polygon such as a rectangle or a parallelogram, the extending direction of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is the extending direction of the long side of the top view shape of each sub-pixel, when the top view shape of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is an ellipse, the extending direction of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is the extending direction of the long axis of the ellipse, and when the top view shape of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is an irregular figure, the extending direction of the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 is the extending direction of the line segment where the two points on the periphery of the irregular figure.
The dashed boxes in fig. 1 and 2 show the parallelogram formed by the four first sub-pixels 11 and the rectangles formed by the two second sub-pixels 12 and the two third sub-pixels 13, respectively. The parallelogram in this embodiment refers to a parallelogram without a rectangle or a square, that is, an included angle between two adjacent sides of the parallelogram is an acute angle or an obtuse angle, or an included angle between two adjacent sides of the parallelogram is a non-right angle.
Specifically, in fig. 1, the plurality of pixel units 10 are arranged such that the geometric centers of the first sub-pixels 11 of the same row are on the same horizontal straight line, the geometric centers of the first sub-pixels 11 of the alternate rows are on the same vertical straight line, and the geometric centers of the first sub-pixels 11 of the adjacent rows are on different vertical straight lines. The arrangement mode enables the geometric centers of the first sub-pixels 11 in the same lighting row to be in the same row when characters are displayed, particularly when the characters are displayed under the condition of a monochromatic background picture, avoids the condition that the horizontal straight line of the characters displays sawteeth, and is beneficial to improving the problem that the straight line is not straight when the characters are displayed. In addition, the geometric centers of the first subpixels 11 interlaced with each other are located on the same vertical straight line L1, which is favorable for improving the situation of sawtooth display of vertical straight lines of characters to a certain extent, and the geometric centers of the first subpixels 11 in adjacent lines are located on different vertical straight lines, so that a longer diagonal line is formed inside a parallelogram formed by four first subpixels 11, the extending direction of the second subpixels 12 located inside the parallelogram can be along the longer diagonal line, which is favorable for increasing the arrangement space of the second subpixels 12 located inside the parallelogram, reducing the difficulty in preparing the second subpixels 12 or the third subpixels 13, improving the preparation yield of the second subpixels 12 or the third subpixels 13, and thus improving the preparation yield of the whole pixel arrangement structure.
In fig. 2, the plurality of pixel units 10 are arranged such that the geometric centers of the first sub-pixels 11 of the same column are on the same vertical straight line, the geometric centers of the first sub-pixels 11 of alternate columns are on the same horizontal straight line, and the geometric centers of the first sub-pixels 11 of adjacent columns are on different horizontal straight lines.
The arrangement mode enables the geometric centers of the first sub-pixels 11 in the same column to be in the same row when characters are displayed, particularly when the characters are displayed under the condition of a monochromatic background picture, so that the condition that the vertical straight lines of the characters display sawteeth is avoided, and the problem that the straight lines are not straight when the characters are displayed is favorably solved. In addition, the geometric centers of the first sub-pixels 11 in the alternate columns are located on the same horizontal straight line L2, which is favorable for improving the situation of saw teeth displayed by the horizontal straight lines of the text to a certain extent, and the geometric centers of the first sub-pixels 11 in the adjacent rows are located on different horizontal straight lines, so that a longer diagonal line is formed inside a parallelogram formed by the four first sub-pixels 11, the extending direction of the second sub-pixel 12 located inside the parallelogram can be along the longer diagonal line, which is favorable for increasing the arrangement space of the second sub-pixel 12 located inside the parallelogram, reducing the difficulty in preparing the second sub-pixel 12 or the third sub-pixel 13, improving the preparation yield of the second sub-pixel 12 or the third sub-pixel 13, and further improving the preparation yield of the whole pixel arrangement structure.
Further, still referring to fig. 1 and fig. 2, since the geometric centers of the two second sub-pixels 12 and the geometric centers of the two third sub-pixels 13 in the pixel unit 10 form a rectangle, in the actual arrangement process, when the plurality of pixel units 10 are sequentially arranged in the horizontal or vertical direction, the second sub-pixels 12 (third sub-pixels 13) in the same row or the second sub-pixels 12 (third sub-pixels 13) in the same column are also all located on the same horizontal or vertical straight line, which is beneficial to further improving the problem of straight line when displaying characters.
It should be noted that the first sub-pixel 11, the second sub-pixel 12, and the third sub-pixel 13 are respectively one of a red sub-pixel, a green sub-pixel, and a blue sub-pixel. Typically, the human eye is most sensitive to green light emitted by the green sub-pixel, so in one embodiment of the present application, still referring to fig. 1 and 2, the first sub-pixel 11 is a green sub-pixel, the second sub-pixel 12 is a blue sub-pixel, and the third sub-pixel 13 is a red sub-pixel. Of course, in other embodiments of the present application, the first sub-pixel 11 may be a green sub-pixel, the second sub-pixel 12 may be a red sub-pixel, and the third sub-pixel 13 may be a blue sub-pixel. The present application does not limit this, which is determined by the actual situation.
In addition, in the three sub-pixels, since the blue sub-pixel has the worst life time under the condition of the same current density, the area of the blue sub-pixel is generally significantly larger than that of the green sub-pixel and the red sub-pixel, that is, in fig. 1 and 2, the sub-pixel with the relatively larger area is the blue sub-pixel, that is, the blue sub-pixel is positioned inside the parallelogram. In some embodiments of the present application, the red sub-pixel may be located inside the parallelogram, and referring to fig. 3, fig. 3 shows a schematic layout of another pixel layout structure, and in fig. 3, the red sub-pixel is located inside the parallelogram.
On the basis of the above embodiments, in an embodiment of the present application, referring to fig. 4, fig. 4 is a schematic layout diagram of another pixel arrangement structure, and the extending direction of two first sub-pixels 11 located at two ends of one diagonal line of the parallelogram is the first direction DR 1.
The extending direction of the two first sub-pixels 11 located at both ends of the other diagonal of the parallelogram is the second direction DR 2.
The first direction DR1 and the second direction DR2 intersect (e.g., are perpendicular).
As shown in fig. 4, when the extending directions of the two first sub-pixels 11 located at both ends of one diagonal line of the parallelogram are the first direction DR 1. When the extending directions of the two first sub-pixels 11 at the two ends of the other diagonal of the parallelogram are the second direction DR2, the four first sub-pixels 11 at the four end points of the parallelogram do not occupy too much space inside the parallelogram, which is beneficial to improving the preparation space of the second sub-pixel 12 inside the parallelogram, thereby improving the preparation yield of the second sub-pixel 12.
Still referring to fig. 4, the extending direction of one second sub-pixel 12 in the pixel unit 10 is the first direction DR1, and the extending direction of the other second sub-pixel 12 is the second direction DR 2.
The extending direction of one third sub-pixel 13 in the pixel unit 10 is the first direction DR1, and the extending direction of the other second sub-pixel 12 is the second direction DR 2.
When the extending direction of one second sub-pixel 12 in the pixel unit 10 is the first direction DR1, the extending direction of the other second sub-pixel 12 is the second direction DR2, the extending direction of one third sub-pixel 13 in the pixel unit 10 is the first direction DR1, and the extending direction of the other second sub-pixel 12 is the second direction DR2, the sub-pixels can be uniformly dispersed, and the visual perception of the display to the user is better.
Accordingly, the extending direction of the second sub-pixel 12 located inside the parallelogram is the second direction DR 2.
The extending directions of the first sub-pixels 11 located at both ends of a diagonal of the parallelogram parallel to the first direction DR1 are the second direction DR 2.
The extending directions of the second sub-pixels 12 located at both ends of a diagonal line of the parallelogram parallel to the second direction DR2 are the first direction DR 1.
The extending direction of the second sub-pixel 12 located inside the parallelogram is the second direction DR2, which is beneficial to fully utilizing the space inside the parallelogram and improving the preparation yield of the second sub-pixel 12.
As described above, the extending directions of the first sub-pixels 11 at two ends of the diagonal line of the parallelogram parallel to the first direction DR1 are the second direction DR2, and the extending directions of the second sub-pixels 12 at two ends of the diagonal line of the parallelogram parallel to the second direction DR2 are the first direction DR1, which is beneficial to increase the overall space inside the parallelogram.
In addition to the above embodiments, in another embodiment of the present application, as shown in fig. 5, fig. 5 is a schematic layout diagram of a pixel layout structure, a plurality of pixel units 10 are further arranged such that the geometric centers of the adjacent first sub-pixels 11 in the first direction DR1 or the second direction DR2 are located on different straight lines, and the geometric centers of the first sub-pixels 11 arranged at intervals are located on the same straight line.
The geometric centers of the adjacent third sub-pixels 13 in the first direction DR1 or the second direction DR2 are located on different straight lines, and the geometric centers of the spaced third sub-pixels 13 are located on the same straight line.
Similarly, the geometric centers of the adjacent first sub-pixels 11 (third sub-pixels 13) in the first direction DR1 or the second direction DR2 are located on different straight lines, and the geometric centers of the first sub-pixels 11 (third sub-pixels 13) arranged at intervals are located on the same straight line, so that on one hand, the problem that oblique lines (straight lines along the first direction DR1 or the second direction DR 2) are not displayed directly during text display can be improved, and on the other hand, more preparation space is provided for other sub-pixels, and the preparation yield is improved.
On the basis of the above embodiment, in a further embodiment of the present application, referring to fig. 6, fig. 6 is a schematic layout diagram of a structure of a pixel unit 10, and a geometric center of a second sub-pixel 12 located inside a parallelogram coincides with a geometric center of the parallelogram.
The geometric center of the first sub-pixel 11 located inside the rectangle does not coincide with the geometric center of the rectangle.
In the present embodiment, the coincidence of the geometric center of the second sub-pixel 12 inside the parallelogram and the geometric center of the parallelogram is beneficial to make the second sub-pixel 12 inside the parallelogram fully utilize the internal space of the parallelogram, and the non-coincidence of the geometric center of the first sub-pixel 11 inside the rectangle and the geometric center of the rectangle is beneficial to make the sub-pixels in the pixel unit 10 uniformly dispersed, so that the visual perception for the user is better when displaying.
On the basis of the above-described embodiment, in an alternative embodiment of the present application, referring to fig. 7, fig. 7 is a schematic layout diagram of a pixel arrangement structure when a plurality of pixel units 10 are arranged such that the geometric centers of the first sub-pixels 11 of the same row are on the same horizontal straight line L3, and the geometric centers of the first sub-pixels 11 of alternate rows are on the same vertical straight line (e.g., the geometric centers of the first sub-pixels 11 of the first row, the third row and the fifth row are on the vertical straight line L4, and the geometric centers of the first sub-pixels 11 of the second row, the fourth row and the sixth row are on the vertical straight line L5).
A distance D1 between a vertical straight line in which the geometric center of the first sub-pixel 11 of the ith row is located and a vertical straight line in which the geometric center of the first sub-pixel 11 of the (i + 1) th row is located (i.e., a vertical distance between the vertical straight line L4 and the vertical straight line L5) is a preset distance; i is a positive integer greater than or equal to 1.
In the present embodiment, the first sub-pixels 11 in adjacent rows are staggered by a predetermined distance, so that the sub-pixels can be arranged with an optimal aperture ratio, and the sub-pixels are vertically staggered by a certain distance in an oblique direction (refer to oblique lines L6 and L7 in fig. 7. in the same pixel unit 10, the second sub-pixel 12 is perpendicular to the extending direction of the first sub-pixel 11 in the direction of oblique line L6, and the geometric centers of the second sub-pixel 12 and the first sub-pixel 11 are not all on the oblique line L6, the geometric center of the first sub-pixel 11 is also staggered by a certain distance compared with the geometric center of the second sub-pixel 12; in the direction of oblique line L7, the extending directions of the first sub-pixel 11 and the third sub-pixel 13 are perpendicular, and the geometric centers of the first sub-pixel 11 and the third sub-pixel 13 are not all on the oblique line L7, and the geometric center of the first sub-pixel 11 is also staggered by a certain distance compared with the geometric center of the third sub-pixel 13), and referring to fig. 7, on the vertical straight lines L4 and L5 and the oblique lines L6 and L7, the geometric centers of the spaced sub-pixels are still on the same straight line/oblique line (for example, on the vertical straight line L4, the first sub-pixel 11 of the first row is on the same vertical straight line L4 as the first sub-pixel 11 of the third row, on the oblique line L6, the geometric center of the second sub-pixel 12 of the first sub-pixel 11 spaced by one in the middle is also on the same oblique line L6), and the arrangement is staggered so that the degree of jagging of the oblique or vertical straight line becomes negligible.
Referring to fig. 8, when the plurality of pixel units 10 are arranged such that the geometric centers of the first sub-pixels 11 of the same column are on the same vertical straight line L10, and the geometric centers of the first sub-pixels 11 of alternate columns are on the same horizontal straight line (e.g., the geometric centers of the first sub-pixels 11 of the first, third, and fifth columns are on a vertical straight line L4, and the geometric centers of the first sub-pixels 11 of the second, fourth, and sixth columns are on a vertical straight line L5).
A distance D2 between a horizontal straight line in which the geometric center of the first sub-pixel 11 in the j-th column is located and a horizontal straight line in which the geometric center of the first sub-pixel 11 in the j + 1-th row is located (i.e., a vertical distance between the horizontal straight line L8 and the horizontal straight line L9) is a preset distance; j is a positive integer greater than or equal to 1.
Similarly, in the present embodiment, the first sub-pixels 11 in adjacent columns are staggered by a predetermined distance, so that the sub-pixels can achieve the optimal aperture ratio arrangement, and at the same time, the sub-pixels are vertically staggered by a certain distance in an oblique direction (i.e. referring to the oblique lines L11 and L12 in fig. 8, in the same pixel unit 10, the oblique line L11 direction is perpendicular to the extending direction of the first sub-pixel 11, and the geometric centers of the second sub-pixel 12 and the first sub-pixel 11 are not both on the oblique line L11, the geometric center of the first sub-pixel 11 is also staggered by a certain distance compared with the geometric center of the second sub-pixel 12; in the oblique line L12 direction, the extending directions of the first sub-pixel 11 and the third sub-pixel 13 are perpendicular, and the geometric centers of the first sub-pixel 11 and the third sub-pixel 13 are not both on the oblique line L12, the geometric center of the first sub-pixel 11 is also staggered by a certain distance compared with the geometric center of the third sub-pixel 13), and referring to fig. 8, on the horizontal straight lines L8 and L9 and the oblique lines L11 and L12, the geometric centers of the spaced sub-pixels are still on the same straight line/oblique line (for example, on the horizontal straight line L8, the first sub-pixel 11 of the first column is on the same horizontal straight line L8 as the first sub-pixel 11 of the third column, on the oblique line L11, the geometric center of the second sub-pixel 12 of the first sub-pixel 11 spaced by one in the middle is also on the same oblique line L11), and the arrangement is staggered so that the degree of jagging of the oblique or vertical straight line becomes negligible.
Optionally, it is found through research that, when the preset distance has a value in a range from one eighth to one sixth of the pixel pitch of the first sub-pixel 11, including an end point value, the sub-pixels in the pixel unit 10 do not affect the arrangement positions of each other, so that the aperture ratio of the pixel unit 10 can obtain an optimal value. When the plurality of pixel units 10 are arranged such that the geometric centers of the first sub-pixels 11 in the same row are on the same horizontal straight line, the pixel pitch of the first sub-pixels 11 is the distance between the geometric centers of the first sub-pixels 11 adjacent in the row direction; when the plurality of pixel units 10 are arranged such that the geometric centers of the first sub-pixels 11 in the same column are on the same vertical line, the pixel pitch of the first sub-pixels 11 is the distance between the geometric centers of the first sub-pixels 11 adjacent in the column direction.
Correspondingly, an embodiment of the present application further provides a display panel, and referring to fig. 9, fig. 9 is a schematic top view of the display panel provided in an embodiment of the present application, where the display panel includes: an array substrate, on which the pixel arrangement structure according to any one of the above embodiments is disposed. Optionally, the extending directions of the first sub-pixel, the second sub-pixel and the third sub-pixel in the pixel arrangement structure are all intersected with the frame of the array substrate.
The display panel includes, but is not limited to, an OLED (Organic Light-Emitting Diode) display panel or a Micro-LED (Micro-Light-Emitting Diode) display panel.
Alternatively, referring to fig. 9, the horizontal direction in the present application refers to a direction parallel to the short frame of the array substrate, and the vertical direction refers to a direction parallel to the long frame of the array substrate. Or, the horizontal direction in this application indicates the direction of arranging of same line of characters when display panel shows, vertical direction then indicate display panel when showing, the direction of arranging of the same line of characters of perpendicular to.
In summary, the embodiment of the present application provides a pixel arrangement structure and a display panel, where the pixel arrangement structure includes a plurality of pixel units, each pixel unit includes four first sub-pixels, two second sub-pixels, and two third sub-pixels, the first sub-pixels, the second sub-pixels, and the third sub-pixels are arranged in a specific manner, and the plurality of pixel units are arranged such that geometric centers of the first sub-pixels in the same row are located on the same horizontal straight line, or the plurality of pixel units are arranged such that geometric centers of the first sub-pixels in the same column are located on the same vertical straight line, so as to improve the problem that straight lines are not straight when characters are displayed.
Meanwhile, the plurality of pixel units are also arranged so that when the geometric centers of the first sub-pixels in the same row are on the same horizontal straight line, the geometric centers of the first sub-pixels in alternate rows are on the same vertical straight line, that is, the geometric centers of the first sub-pixels in adjacent rows can be on different vertical straight lines, or when the geometric centers of the first sub-pixels in the same column are on the same vertical straight line, the geometric centers of the first sub-pixels in alternate columns are on the same horizontal straight line, that is, the geometric centers of the first sub-pixels in adjacent columns can be on different horizontal straight lines, so that on the basis of improving the problem that the straight line display of characters is not straight to a certain extent, the length of one diagonal line of a parallelogram formed by the geometric centers of the four first sub-pixels in a pixel unit is increased, and therefore, the second sub-pixel positioned in the parallelogram can extend along the diagonal line of a longer parallelogram, the preparation space of the second sub-pixel positioned in the parallelogram is increased, the preparation process requirement for the second sub-pixel is reduced, and the preparation yield of the pixel arrangement structure is improved.
