Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. The 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.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
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 in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As described in the background, most of the current display panels use three-color sub-pixels as primary colors for color display, and especially, RGB is the most common of the three primary colors. There are many colorization methods for the OLED screen body, and the OLED colorization technology which is mature and mass-produced at present is the OLED evaporation technology, and the conventional RGB strip arrangement mode is adopted for evaporation. The best display picture effect is a side-by-side mode, specifically, three sub-pixels (sub-pixels) of red, green and blue (R, G, B) are arranged in one Pixel (Pixel) unit, each sub-Pixel is rectangular and is provided with an independent organic light emitting component, and the organic light emitting components are formed at corresponding Pixel positions on an array substrate by using an evaporation film forming technology through a high-precision Metal Mask (FMM), which is usually referred to as an evaporation Mask for short. The technical focus of fabricating high PPI (Pixel Per Inch, number of pixels) OLED display screens is on FMM with fine and mechanically stable features and Pixel arrangement. Specifically, the FMM mask should minimize the occurrence of warpage, fracture, and other problems, and avoid the defects that the vapor deposition film layer is blunted and shifted, which affect the vapor deposition quality. The arrangement of the pixels is a main cause for determining whether the FMM is easily warped and broken. That is, the arrangement of the pixels and the sub-pixels largely determines the mechanical performance of the FMM, and the mechanical performance of the FMM largely determines the quality of the vapor deposition.
The pixel arrangement shown in fig. 1 in the prior art is usually performed by using the FMM shown in fig. 2, which includes several evaporation openings B and a shielding region C, and the shielding region between two adjacent evaporation openings B in the same column is called a bridge (bridge). Since the sub-pixels of the same color are aligned up and down in the arrangement of fig. 1, the evaporation openings B of the FMM must also be aligned, which may cause a connection bridge (bridge) between two adjacent evaporation openings B in the longitudinal direction to have a risk of disconnection. Furthermore, the evaporation openings B of the FMM need to correspond to predetermined pixel positions, and according to the conventional pixel arrangement, the alignment space between the FMM and the sub-pixel region is reduced, which may cause defects of color missing or color mixing.
FIG. 3 is a schematic layout of another prior art pixel arrangement; fig. 4 is a schematic layout diagram of another pixel layout structure in the prior art. As shown in fig. 3, each column includes a plurality of R, G, B repeating units arranged in a straight line, and the repeating units in adjacent rows are arranged in a staggered manner such that a sub-pixel R, G corresponds to a B sub-pixel. As shown in fig. 4, the pixel arrangement structure includes a plurality of repeating units arranged in an array, each repeating unit includes R, G sub-pixels arranged in a straight line, and the B sub-pixels are located at one side of the R |, G sub-pixels and are arranged in a single line. Although high resolution can be realized in the pixel arrangement structures of fig. 3 and 4, as in the pixel arrangement structure of fig. 3, R, G, B subpixels are in a row, which increases difficulty in routing the array and difficulty in manufacturing and screening the FMM, in the pixel arrangement structure of fig. 4, R, G is located in the same row, which also increases difficulty in routing the array, and the subpixels B are not uniform in distance in the row direction and two adjacent subpixels B are closer, which is not beneficial to screening the FMM and affects the display effect.
Meanwhile, in the prior art, a camera, a receiver, an infrared sensing element and the like are arranged in a slotted area through slotting/punching (Notch) on a display screen, and the slotted area is not used for displaying pictures, such as a bang screen in the prior art, or a mode of opening holes on the screen is adopted. The display area of the display screen has special-shaped edges, and in the three pixel arrangement structures, the special-shaped edge area of the display area has edge sawtooth phenomenon. In the existing design, a pixel group with slightly low brightness can be added in the edge area to change the sawtooth phenomenon, and the brightness is controlled by matching with an algorithm in a driving chip correspondingly. However, in the case of adding an algorithm, although the edge aliasing phenomenon can be improved, the complexity of the algorithm becomes large, and the design difficulty of the driving chip is increased.
In order to solve the above problem, the utility model provides a pixel arrangement structure, display panel and display device can improve above-mentioned problem better.
Before describing the present invention in detail, some contents of the present invention will be explained first, so as to understand the technical solution of the present invention more clearly.
Row direction/column direction: the row direction refers to a lateral or horizontal direction as shown in fig. 5 and 8, and the column direction refers to a longitudinal or vertical direction as shown in fig. 5 and 8.
Fig. 5 is a schematic layout diagram of a pixel layout structure according to an embodiment of the present invention; FIG. 6 is a schematic diagram of a simulated arrangement of the pixel arrangement shown in FIG. 5 in a special-shaped edge region of a display area; FIG. 7 is a schematic diagram showing the distance between two opposite edges of two third sub-pixels corresponding to the pixel arrangement shown in FIG. 5; FIG. 8 is a schematic view of the stretching force of the FMM corresponding to the pixel arrangement shown in FIG. 5.
Referring to the drawings, a pixel arrangement structure according to an embodiment of the present invention includes a plurality of pixel groups 1.
Each pixel group 1 comprises one first sub-pixel 12, one second sub-pixel 14 and two third sub-pixels 16.
In each pixel group 1, the first sub-pixel 12 and the second sub-pixel 14 are arranged along a row or a column direction, and the two third sub-pixels 16 are arranged along a column or a row direction on two sides of a central connecting line of the first sub-pixel 12 and the second sub-pixel 14.
Further, the central connecting line of the first sub-pixel 12 and the second sub-pixel 14 is vertically bisected by the central connecting line of the two third sub-pixels 16. Therefore, the arrangement positions of the sub-pixels are more uniform, and the uniform display effect is favorably realized.
Specifically, the first sub-pixel 12, the second sub-pixel 14, and the third sub-pixel 16 are different colors, and the color of the first sub-pixel 12, the second sub-pixel 14, and the third sub-pixel 16 may be one of red, blue, and green.
In one implementation, the plurality of pixel groups 1 are arranged in a plurality of columns or rows, and the pixel groups 1 in odd columns or rows are arranged in a staggered manner with the pixel groups 1 in even columns or rows. In the present example, the pixel group 1 of the odd-numbered column is arranged offset from the pixel group 1 of the even-numbered column.
Further, the arrangement structure of the pixel groups 1 of adjacent odd columns or rows is the same. The pixel groups 1 of adjacent even columns or rows have the same arrangement structure.
It should be understood that the first sub-pixel 12 and the second sub-pixel 14 in the pixel group 1 of the adjacent odd column or row are spaced by the third sub-pixel 16 in the pixel group 1 of the even column or row. In each pixel group 1, the first sub-pixel 12 and the second sub-pixel 14 are arranged along a row or a column direction, and the two third sub-pixels 16 are arranged on two sides of a central connecting line of the first sub-pixel 12 and the second sub-pixel 14 along the column or the row direction; thus, the first sub-pixel 12, the second sub-pixel 14 and one of the third sub-pixels 16 can form a pixel unit, and the first sub-pixel 12, the second sub-pixel 14 and another of the third sub-pixels 16 can also form a pixel unit, so that by sharing the pixels of the first sub-pixel 12 and the second sub-pixel 14, 4 sub-pixels can simulate to realize a higher PPI.
Referring to fig. 5 and 6, in the embodiment of the present invention, the center connecting line of the first sub-pixel 12, the second sub-pixel 14 and the third sub-pixel 16 in each pixel group 1 forms a virtual triangle, two sides of the virtual triangle respectively form a first angle α and a second angle β with the row or column direction, and 30 ° ≦ α ≦ 60 °, and 30 ° ≦ β ≦ 60 °.
In some embodiments, the first sub-pixel 12 and the second sub-pixel 14 are arranged in a same row or column, and the third sub-pixel 16 is arranged in another adjacent row or column, so that the connecting lines of the centers of the three sub-pixels form a virtual triangle.
It should be noted that the triangle is a closed figure formed by sequentially connecting three line segments which are not on the same straight line in the same plane end to end, and one of the edges of the triangle is defined as a bottom edge, and the other two edges are side edges (or waist edges).
Specifically, in the example shown in fig. 5, in each pixel group 1, the first sub-pixel 12 and the second sub-pixel 14 are arranged along the row direction, and the line connecting the centers of the first sub-pixel 12 and the second sub-pixel 14 is taken as the base, and one of the other two sides is a side forming a first angle α with the row direction, and the other side is a side forming a second angle β with the row direction.
It should be understood that the plurality of pixel groups 1 are repeatedly arranged, and two sides of the first virtual triangle formed by the connecting line of the centers of the first sub-pixel 12, the second sub-pixel 14 and any third sub-pixel 16 in each pixel group 1 form a first angle α and a second angle β with the row or column direction, so that as the plurality of pixel groups are repeatedly arranged, the connecting line of the edges of the plurality of sub-pixels located at the special-shaped edge W (e.g. arc) of the display area and the tangent line of the special-shaped edge W tend to coincide or be parallel, so that the connecting line of the edges of the plurality of sub-pixels is more smooth and close to the shape of the special-shaped edge W, thereby reducing the jaggy feeling of the image at the special-shaped edge W and being beneficial to improving the display effect of the display panel.
It is worth emphasizing that under the premise of the same display area and the same high PPI, the shape and size of the sub-pixels and the size of the sub-pixels and the center-to-center distance between the sub-pixels in the pixel group 1 all change the included angle between the two sides of the virtual triangle and the row or column direction.
In some embodiments of the present invention, a third sub-pixel 16 of a pixel group 1 in the same column or row is adjacent to a third sub-pixel 16 of an adjacent pixel group 1. The adjacent two third sub-pixels 16 can share the mask opening, so that the aperture ratio of the third sub-pixels 16 can be improved.
Further, two adjacent third sub-pixels 16 in two adjacent pixel groups 1 in the same column or row have two pixel edges opposite to each other, that is, the two adjacent third sub-pixels 16 are arranged edge to edge.
In a preferred embodiment, two pixel sides of the adjacent two third sub-pixels 16 are disposed obliquely with respect to the row or column direction.
Preferably, the third sub-pixel 16 has a diamond shape. In a specific example, two opposite edges of the two adjacent third sub-pixels 16 are arranged in parallel with each other.
In the example shown in fig. 5, the two pixel sides of the two adjacent third sub-pixels 16 are disposed at a first angle α to the row direction, it is understood that in other examples, the first sub-pixel 12 and the second sub-pixel 14 are also arranged in the row direction in each pixel group 1, and the two pixel sides of the two adjacent third sub-pixels 16 may be disposed at a second angle β to the row direction, which is not illustrated here.
Referring to fig. 7, compared to the case where the sides of the two adjacent third sub-pixels 16 are parallel to the row or column direction (when the distance between the two sides of the two adjacent third sub-pixels 16 is L1), the distance L2 between the two sides of the two adjacent third sub-pixels 16 can be increased (where L2> L1), so that the problems of too close light emitting centers and too high light emitting brightness of the two same-color third sub-pixels 16 are reduced, and especially when the third sub-pixel 16 is a green sub-pixel, the display effect can be improved.
In some embodiments of the present invention, the color of the sub-pixels located in the same column or the same row is the same in the column or row direction.
For example, referring to fig. 5, in the column direction, the first sub-pixels 12 are located in the same column; the second sub-pixel 14 is located in another column and the third sub-pixel 16 is located between the columns formed by the first sub-pixel 12 and the second sub-pixel 14.
For example, referring to fig. 5 and fig. 7, centers of the same color sub-pixels in the pixel groups 1 of two adjacent odd-numbered columns are located on the same straight line, centers of the same color sub-pixels in the pixel groups 1 of two adjacent even-numbered columns are located on the same straight line, and the same color sub-pixels in the pixel groups 1 of the adjacent odd-numbered columns and the same color sub-pixels in the pixel groups 1 of the even-numbered columns are staggered. In other words, the arrangement of the sub-pixels in the pixel group 1 in all the odd-numbered columns is the same, and the arrangement of the sub-pixels in the pixel group 1 in the even-numbered column is the same, but the light emitting areas of the sub-pixels in the same color in the odd-numbered columns and the even-numbered columns are not aligned but are arranged to be shifted (shifted) from each other, and the light emitting areas of the sub-pixels in the same column are vertically aligned. In the embodiments shown in fig. 5 and 7, the centers of the first sub-pixels 12 in the pixel groups 1 of the same column are located on one straight line, the centers of the second sub-pixels 14 in the pixel groups 1 of the same column are located on another straight line, and the centers of the third sub-pixels 16 in the pixel groups 1 of the same column are located on another straight line.
Thus, on the one hand, each pixel group 1(pixel) in the pixel arrangement is composed of three colors (RGB three colors), 4 sub-pixel groups 1, and full color display in the true sense can be realized. In addition, the sub-pixels with three colors are arranged in the sub-pixel rows or columns of the pixel arrangement structure, the colors of the sub-pixels in the same row or column are the same, the distance between the sub-pixels in the same color in two adjacent rows or columns is wider, and compared with the arrangement mode that the sub-pixels with one color are only densely distributed in a certain direction, the arrangement mode has the advantages that the display in the row and column directions is uniform, and the display effect is better. Referring to fig. 8, on the other hand, the sub-pixels with the same color are arranged in a staggered manner, and under the same process conditions, the sub-pixels arranged in a staggered manner are adopted, so that the available distance between the openings of the same sub-pixels is increased, the difficulty of the mask manufacturing process and the evaporation process is reduced, the size of the pixel group 1 can be reduced, and the manufacturing of the high-resolution display screen is facilitated. And in the row direction and the column direction, the distance between two adjacent same-color sub-pixels is wider, so that the transmission of the tensile force F is facilitated, the deformation of a Mask is reduced, and the difficulty of a fine metal Mask plate manufacturing process and an evaporation process is also reduced.
On the other hand, the centers of the sub-pixels with the same color in the pixel group 1 in the same row are positioned on the same straight line, and the array wiring connected with the sub-pixels can be in a row, so that the arrangement of the array wiring is facilitated, the distance from the anode via hole to the pixel definition layer is favorably reduced, the manufacturing difficulty of the display panel is reduced, and the manufacturing of the high-resolution display screen is favorably realized.
It will be readily appreciated that since the luminous efficiency of the blue sub-pixel is generally the lowest, and accordingly the required luminous area is greater, in some embodiments the area of the blue sub-pixel is greater than the area of the red sub-pixel and the area of the green sub-pixel. Specifically, in some embodiments, the first sub-pixel 12 is blue, the second sub-pixel 14 is red, the third sub-pixel 16 is green, and the aperture area of the first sub-pixel 12 is larger than the aperture area of the third sub-pixel 16 and is also larger than the aperture area of the second sub-pixel 14. In addition, the opening area of the third sub-pixel 16 can be equal to the opening area of the second sub-pixel 14, so that the pixel structure has a better display effect.
It should be noted that the opening area of the third sub-pixel 16 and the opening area of the second sub-pixel 14 may not be equal, and in practical applications, the opening area of each sub-pixel may be adjusted accordingly as needed.
In some embodiments of the present invention, the plurality of sub-pixels have the same shape. For example, the shape of the first sub-pixel 12, the second sub-pixel 14, and the third sub-pixel 16 may be a triangle, a quadrangle, a hexagon, or other polygons, and the like, which is not limited herein. Therefore, the pixel arrangement can be ensured to be more uniform, the connecting line of the sub-pixel edge of the special-shaped edge W of the display area is smoother, and the saw tooth feeling of the special-shaped edge W of the display area is further reduced. As a preferred embodiment, the shape of the sub-pixels may be a diamond shape, so that on one hand, the arrangement of the sub-pixels in the pixel group 1 may be more compact, which is beneficial to improving the aperture ratio of the display panel; on the other hand, the side edges of the sub-pixels are arranged in an included angle with the row direction or the column direction, and the side edge corresponding to each sub-pixel is more parallel to the side edge of the first virtual triangle, so that the saw tooth feeling of the special-shaped edge W of the display area can be further reduced, and the display effect is further improved.
In some embodiments of the present invention, regarding the first sub-pixel 12 and the second sub-pixel 14, the distance between the light emitting area center points of the sub-pixels (e.g. the first sub-pixel 12) with the same color in the odd-numbered columns and the even-numbered columns is the width of X pixel groups 1 apart, that is, the distance between the light emitting area center points of the two sub-pixels with the same color located closest to (adjacent to) each other in the row direction is the width of X pixel groups 1. With respect to the first sub-pixel 12 and the second sub-pixel 14, the distance between the center points of two nearest sub-pixels of the same color in the same column is the width of Y pixel groups 1 apart. When the shape and size of the sub-pixels are equal, X/Y is 2N, and N is an integer greater than or equal to 1. However, in other embodiments, the size of the offset between adjacent odd and even rows of same-color subpixels may not be strictly limited to X subpixels.
In this particular example, X is 2 and Y is 1.
In addition, the distance between a sub-pixel and an adjacent sub-pixel of the same color in the row or column direction is the distance between the center lines of the adjacent sub-pixels of the same color in the row or column direction. For example, in some embodiments, the centers of the sub-pixels of the same color in the pixel groups 1 located in the same column are located on a straight line, and thus, the distance between the sub-pixels of the same color in two pixel groups 1 adjacent in the column direction is the center distance of the two sub-pixels. And the sub-pixels of the same color in the two pixel groups 1 adjacent in the row direction are respectively located in the two adjacent sub-pixel rows or columns, so that the distance between the sub-pixels of the same color in the two pixel groups 1 adjacent in the row direction is the distance between the center lines of the two.
It is understood that the above-mentioned pixel arrangement structure may be modified appropriately, such as being rotated by 90 degrees, 180 degrees, 270 degrees, etc., and the positions of the first sub-pixel 12, the second sub-pixel 14 and the third sub-pixel 16 may be inter-modulated, which is not illustrated herein.

The display panel may be an OLED light emitting display panel, a liquid crystal display panel, a Micro LED, a quantum dot display panel, and the like, which is not limited herein.
