Detailed Description
The present invention will be described more fully hereinafter in order to facilitate an understanding of the present invention, and preferred embodiments of the present invention are set forth. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, a pixel arrangement structure 10 according to an embodiment of the present invention includes a repeating unit 100, where the repeating unit 100 has a quadrilateral shape, for example: square, rectangular, diamond, etc. Preferably, the repeating unit 100 is square. It is understood that the shape of the repeating unit 100 refers to a shape in which the sub-pixels constituting the repeating unit 100 are commonly spliced. According to the arrangement mode of each sub-pixel, a plurality of dividing lines exist, and it is understood that in the display panel, the dividing lines are pixel banks formed by a pixel definition layer (pixel definition layer) and the like, and due to the differences of preparation processes, equipment and the like, the intervals among the sub-pixels are different, so that the overall shape of the repeating unit has a certain deviation, so long as the error is within the acceptable range in the field, the errors are understood to be all within the protection scope of the invention.
In addition, in one embodiment, the pixel arrangement structure includes a plurality of repeating units 100, and the plurality of repeating units 100 are arranged along a row direction and a column direction to form an array structure. Preferably, in the array structure, two adjacent repeating units are axisymmetric or centrosymmetric in the row direction or the column direction.
It is understood that in the row direction or the column direction, the adjacent two repeating units are axisymmetric, which means that the arrangement of each sub-pixel in the adjacent two repeating units is axisymmetric, and the symmetry axis is a direction perpendicular to the arrangement direction of the two repeating units. For example, in fig. 1, in the row direction, two adjacent repeating units are axisymmetric in the direction perpendicular to the row direction (i.e., the direction parallel to the column direction);
in the row direction or the column direction, the fact that two adjacent repeating units are symmetrical in the center means that each sub-pixel in the two adjacent repeating units is symmetrical in the center, and the symmetry center is located in the middle of the two repeating units. As shown in fig. 2, two adjacent repeating units are arranged in a central symmetry manner in the row direction, i.e., in a "one-positive-one-negative" manner in the row direction.
In addition, it should be noted that, in the same pixel arrangement structure, part of the adjacent repeating units may be axisymmetric, as shown in fig. 3 a; part of the adjacent repeat units are centrosymmetric, as shown in figure 3 b.
As shown in fig. 4, the repeating unit 100 includes two first sub-pixels 110, two second sub-pixels 120, two third sub-pixels 130 and one fourth sub-pixel 140, wherein the two first sub-pixels 110, the two second sub-pixels 120 and the two third sub-pixels 130 are arranged around the fourth sub-pixel 140, and the two first sub-pixels 110, the two second sub-pixels 120 and the two third sub-pixels 130 are axisymmetrically distributed with respect to the same symmetry axis, i.e. the symmetry axes of the two first sub-pixels 110, the two second sub-pixels 120 and the two third sub-pixels 130 overlap, and the symmetry axis passes through the center point of the fourth sub-pixel 140.
In this way, the fourth subpixel 140 becomes a common subpixel, forms one subpixel group with the first subpixel 110, the second subpixel 120, and the third subpixel 130 on one side (a side) of the symmetry axis, and forms one subpixel group with the first subpixel 110, the second subpixel 120, and the third subpixel 130 on the other side (B side) of the symmetry axis, respectively; in addition, when the repeating units are repeatedly arranged, three sub-pixels in one of the adjacent repeating units and one sub-pixel in the other repeating unit may form one sub-pixel group, for example, in fig. 1, two adjacent repeating units, for example, the first repeating unit 100 and the second repeating unit 200, respectively, and the second sub-pixel 120, the third sub-pixel 130, and the fourth sub-pixel 140 in the first repeating unit 100 and the first sub-pixel 210 in the second repeating unit 200 may form one pixel group. Similarly, a pixel group can be formed on the other side of the symmetry axis, so that the number of pixel groups in unit area can be increased more conveniently, and the resolution of the display panel can be improved.
Moreover, the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 of the pixel arrangement structure 10 are axisymmetrically arranged around the fourth sub-pixel 140 and spliced into a quadrilateral, so that the light-emitting colors of the adjacent sub-pixels are the same (two adjacent first sub-pixels 110 and two adjacent third sub-pixels 130 shown in fig. 1), and the sub-pixels with the same color in the adjacent repeating units can be converged together (the second sub-pixel 120 shown in fig. 1), so that the sub-pixels with the same light-emitting color can share one evaporation opening, thereby effectively solving the high precision limitation of the evaporation mask plate, and reducing the preparation difficulty while improving the resolution of the display panel.
In addition, in the present invention, at least three emission colors of the first sub-pixel 110, the second sub-pixel 120, the third sub-pixel 130 and the fourth sub-pixel 140 are provided, and the emission colors of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 are different, and the specific emission colors may be selected according to factors such as device requirements, sub-pixel area and manufacturing process, and are not particularly limited herein.
For example: one of the first, second and third sub-pixels 110, 120 and 130 has a red emission color, one has a green emission color, and one has a blue emission color; the light emission color of the fourth subpixel 140 is red, blue, green, or white. If the brightness of the color display needs to be improved, a fourth sub-pixel with white color can be selected; if the color saturation or color shift is to be improved, the fourth subpixel 140 may have the same emission color as one of the first subpixel 110, the second subpixel 120, and the third subpixel 130.
Further, when the emission color of the fourth subpixel 140 is white, the emission color of the largest area subpixel among the first, second and third subpixels 110, 120 and 130 is blue or green;
when the light emitting color of the fourth subpixel 140 is red, blue, or green, the light emitting color of the subpixel having the smallest area among the first, second, and third subpixels 110, 120, and 130 is the same as the fourth subpixel 140.
In the repeating unit 100, adjacent sub-pixels are preferably arranged in an edge-to-edge manner, and more preferably, adjacent two edges of the adjacent sub-pixels are parallel to or overlap each other. For example: as shown in fig. 1, the second sub-pixel 120 is adjacent to the first sub-pixel 110 and the third sub-pixel 130, and the edges of the second sub-pixel 120 and the first sub-pixel 110 adjacent to each other are arranged in an edge-to-edge manner, and the edges of the second sub-pixel 120 and the third sub-pixel 130 adjacent to each other are arranged in an edge-to-edge manner, so as to reduce the difficulty in preparing the mask.
In addition, it is preferable that one first subpixel 110, one second subpixel 120, and one third subpixel 130 are axisymmetrically arranged in the column or row direction in the same repeating unit; the line of symmetry is parallel to the column or row direction.
Still further, it is preferable that each of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 is polygonal or polygonal having one circular arc side. It is understood that a polygon having one circular arc side means that one side of the polygon is a circular arc side, and the arc of the circular arc is not particularly limited, and is selected according to the area of the sub-pixel, and may be, for example, 1/6 circular arc, 1/4 circular arc, or the like.
The shape of the fourth subpixel 140 is not particularly limited, and may be triangular, circular, elliptical, or the like. It should be noted that, the shape of the fourth subpixel 141 may be the same as or different from the shape of the region surrounded by the two first subpixels 110, the two second subpixels 120, and the two third subpixels 130, and preferably, the shape of the fourth subpixel 140 is the same as the shape of the region surrounded by the two first subpixels 110, the two second subpixels 120, and the two third subpixels 130, so as to facilitate the preparation of the mask plate of each subpixel.
