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 shown in fig. 1 and 2, a pixel arrangement structure 10 according to an embodiment of the present invention includes a plurality of repeating units 100 (shown in fig. 2 as a), where the repeating units 100 include: a first subpixel group 110, a second subpixel group 120, and two third subpixel groups 130; the first sub-pixel group 110, the second sub-pixel group 120, and the third sub-pixel group 130 emit light of different colors. The first sub-pixel group 110 and the second sub-pixel group 120 have the same shape and are in a hexagon shape including a hollow area, and the first sub-pixel group 110 and the second sub-pixel group 120 are arranged in an edge-to-edge manner; the two third sub-pixel groups 130 are respectively disposed in the hollow regions within the first sub-pixel group 110 and the second sub-pixel group 120.
Further, the first sub-pixel group 110, the second sub-pixel group 120, and the third sub-pixel group 130 are respectively composed of a plurality of sub-pixels having the same emission color, and a connection line between a center point of the first sub-pixel group 110 and a center point of the second sub-pixel group 120 forms an included angle with a row direction and a column direction.
The light emitting colors of the first sub-pixel group 110, the second sub-pixel group 120, and the third sub-pixel group 130 are not particularly limited, and are selected according to the color of light to be finally obtained, for example, red, green, and blue are used to obtain white light, that is, one of the first sub-pixel group 110, the second sub-pixel group 120, and the third sub-pixel group 130 has a red light emitting color, one has a green light emitting color, and one has a blue light emitting color, and preferably the third sub-pixel group 130 has a green light emitting color, so as to control the area of the light emitting device.
The area of each sub-pixel group is not particularly limited, and may be determined, for example, according to the contribution rate of the color constituting white light and the lifetime of the light-emitting material that emits the color.
In the present invention, the first sub-pixel group 110 and the second sub-pixel group 120 have the same shape and are in a hexagonal shape including a hollow region, and preferably, the first sub-pixel group 110 and the second sub-pixel group 120 have a regular hexagonal shape including a hollow region. It should be understood that the shape of the sub-pixel group refers to a shape formed by splicing a plurality of sub-pixels constituting the sub-pixel group, and due to the requirement of the manufacturing process, etc., gaps within the acceptable range in the art may exist between the sub-pixels, and it should be understood that the invention is within the protection scope. In addition, the regular hexagon in the present invention is not a strict regular hexagon, and each side may have an error acceptable in the art due to a manufacturing process, etc.
In addition, in the present invention, the first subpixel group 110 and the second subpixel group 120 are disposed side-to-side; furthermore, the number of the repeating units of the pixel arrangement structure is several, in the column or row direction, two first sub-pixel groups 110 of two adjacent repeating units are arranged edge to edge, and two second sub-pixel groups 120 of two adjacent repeating units are arranged edge to edge; in the row or column direction, the adjacent first sub-pixel group 110 and second sub-pixel group 120 in two adjacent repeating units are arranged in pairs of edges.
As shown in fig. 2 a, it is preferable that adjacent sides of the first subpixel group 110 and the second subpixel group 120 are parallel to or coincide with each other (see a dotted line frame E) to facilitate the arrangement of the repeating units. It is understood that the interval between the first subpixel group 110 and the second subpixel group 120 is determined according to a manufacturing process, etc., and is not particularly limited. As shown in fig. 1, when the first sub-pixel group 110 and the second sub-pixel group 120 are regular hexagons including a hollow region, the adjacent sides of the first sub-pixel group 110 and the second sub-pixel group 120 of each repeating unit are parallel or overlapped, so that the repeating units are repeatedly arranged in the row direction and the column direction to form a honeycomb-shaped pixel arrangement structure, thereby fully utilizing the space and increasing the number of pixel units in a unit area.
Specifically, the method comprises the following steps: referring to fig. 3, taking the four repeating units shown in fig. 1 as an example, the first repeating unit 100, the second repeating unit 200, the third repeating unit 300 and the fourth repeating unit 400 are respectively, the adjacent sides of the first sub-pixel group 110 and the second sub-pixel group 120 of each repeating unit are parallel or coincident with each other, so that the first sub-pixel group 110 of the first repeating unit 100, the first sub-pixel group 210 of the second repeating unit 200, the first sub-pixel group 310 of the third repeating unit 300 and the first sub-pixel group 410 of the fourth repeating unit 400 are arranged around the second sub-pixel group 120 of the first repeating unit 100, and the adjacent sides of the first sub-pixel group 210 of the second repeating unit 200 and the second sub-pixel group 120 of the first repeating unit 100 are parallel or coincident with each other, and similarly, the adjacent sides of the first sub-pixel group 310 of the third repeating unit 300 and the second sub-pixel group 120 of the first repeating unit 100 are parallel or coincident with each other, the adjacent sides of the first sub-pixel group 410 of the fourth repeating unit 400 and the second sub-pixel group 120 of the first repeating unit 100 are parallel or coincident with each other. In this way, the sub-pixels of the second sub-pixel group 120 of the first repeating unit 100 can be shared by the sub-pixels of the sub-pixel groups of the repeating units located at the periphery thereof, thereby increasing the number of pixel units per unit area.
Furthermore, as shown in a in fig. 2, the third sub-pixel group 130 in the present invention is disposed in the hollow region in the first sub-pixel group 110 and the second sub-pixel group 120, such that, as shown in b in fig. 2, three of a sub-pixel in the third sub-pixel group 130, a sub-pixel in the second sub-pixel group 120, and a sub-pixel in the first sub-pixel group 110 form a pixel unit 1000.
It can be understood that the hollow region of the third sub-pixel group 130 disposed in the first sub-pixel group 110 and the second sub-pixel group 120 means that each sub-pixel of the third sub-pixel group 130 is surrounded by each sub-pixel of the first sub-pixel group 110 and the second sub-pixel group 120, i.e., each sub-pixel of the third sub-pixel group 130 is shared by the sub-pixels of the first sub-pixel group 110 and the second sub-pixel group 120 located at the periphery thereof. In this way, when the first sub-pixel group 110 and the second sub-pixel group 120 are respectively composed of 4 sub-pixels, and the third sub-pixel group 130 is composed of 2 sub-pixels, and each sub-pixel of the third sub-pixel 130 can be shared by the surrounding sub-pixels to respectively form 2 pixel units, each repeating unit 100 can form 8 pixel units (see the small triangle in fig. 1) in cooperation with the adjacent repeating unit, thereby improving the resolution of the display panel.
Further, the third subpixel group 130 filling the hollow regions of the first subpixel group 110 and the second subpixel group 120 has a diamond shape or a rectangular shape.
Further, two opposite vertices of the third subpixel group 130 disposed within the first subpixel group 110 coincide with two opposite vertices of the first subpixel group 110; two opposite vertices of the third sub-pixel group 130 disposed within the second sub-pixel group 120 coincide with two opposite vertices of the second sub-pixel group 120 to facilitate the formation of a pixel unit.
Further, the two third sub-pixel groups 130 in each repeating unit are in central symmetry, and the center of symmetry is on a first straight line, wherein the first straight line is parallel to the edge of the first sub-pixel group 110 close to the second sub-pixel group 120, so as to facilitate uniform light emission.
It is understood that the number of sub-pixels in each sub-pixel group is not particularly limited, and preferably, the third sub-pixel group 130 is composed of 2n sub-pixels, the first sub-pixel group 110 and the second sub-pixel group 120 are composed of 4n sub-pixels, n is an integer greater than or equal to 1, and more preferably n is 1. In this way, the preparation process can be simplified, for example: the first sub-pixel group 110 includes four sub-pixels, the second sub-pixel group 120 includes four sub-pixels, and the third sub-pixel group 130 includes two sub-pixels, so that only 2 isolation lines (i.e., the division lines divided into 4 sub-pixels) are required in the first sub-pixel group 110 and the second sub-pixel group 120, and only 1 isolation line is required in the third sub-pixel group 130, thereby simplifying the manufacturing process. And each sub-pixel group is divided into a plurality of sub-pixels, namely the sub-pixels are gathered together, and the arrangement mode of the sub-pixel groups is combined, so that more panel design requirements of driving TFTs can be saved, and the design difficulty and the complexity of the manufacturing process of the panel are greatly reduced.
The area of the sub-pixels in each sub-pixel group may be equal or different, and is not particularly limited, but it is preferable that the area of the sub-pixels in each sub-pixel group is equal to improve the uniformity of light emission.
As shown in a in fig. 2, four sub-pixels of the first sub-pixel group 110 are a first sub-pixel 111, a second sub-pixel 112, a third sub-pixel 113, and a fourth sub-pixel 114, respectively, the first sub-pixel 111 and the second sub-pixel 112 are arranged in axial symmetry along the column direction, the third sub-pixel 113 and the fourth sub-pixel 114 are arranged in axial symmetry along the column direction, the first sub-pixel 111 and the third sub-pixel 113 are arranged in axial symmetry along the row direction, and the second sub-pixel 112 and the fourth sub-pixel 114 are arranged in axial symmetry along the row direction. Each sub-pixel in the second sub-pixel group 120 is the same as the first sub-pixel group 110, and the description thereof is omitted.
Further, the two sub-pixels in the third sub-pixel group 130 are arranged axially symmetrically along the column direction.
The arrangement is such that each sub-pixel in the first sub-pixel group 110 and the second sub-pixel group 120 is quadrilateral, taking the quadrilateral first sub-pixel 111 in the first sub-pixel group 110 as an example (as shown in a in fig. 2), the first side a of the first sub-pixel 111 forms one side of the hexagonal first sub-pixel group 110, the second side b is parallel to or coincides with the side adjacent to the third sub-pixel group 113, the third side c is parallel to or coincides with the side adjacent to the second sub-pixel 112, and the fourth side d is on a straight line with the side adjacent to the second sub-pixel 112 and forms a side of a hexagon together. The second sub-pixel 112, the third sub-pixel 113 and the fourth sub-pixel 114 are the same as the first sub-pixel, and are not described herein again.
Furthermore, the pixel arrangement structure of the present invention includes a plurality of repeating units, wherein the repeating units are repeatedly arranged along the row direction and the column direction, and an array structure is formed in which the emission colors of the adjacent sub-pixel groups in one direction are the same and the emission colors of the adjacent sub-pixel groups in the other direction are different in the row direction and the column direction. That is, in the pixel arrangement structure 10, the emission colors of two adjacent sub-pixel groups in the column direction are the same, and the emission colors of two adjacent sub-pixel groups in the row direction are different; or the light emission colors of two adjacent sub-pixel groups in the row direction are the same, and the light emission colors of two adjacent sub-pixel groups in the column direction are different.
As shown in fig. 1, the first sub-pixel group 110 is arranged in odd-numbered columns and the second sub-pixel group 120 is arranged in even-numbered columns in the column direction, and the first sub-pixel group 110 and the second sub-pixel group 120 are arranged in a staggered manner in the row direction, so that the third sub-pixel group 130 is arranged in a staggered manner in the row direction and the column direction.
Therefore, as the light emitting colors of the sub-pixel groups adjacent to each other along one direction of the repeating unit are the same, the sub-pixel groups with the same light emitting colors can be printed or evaporated together, so that the printing or evaporation area can be increased, and the high-precision requirement on the size of the metal shadow mask pattern in the evaporation process and the high-precision requirement on printing equipment can be avoided. And the light emitting colors of the adjacent sub-pixel groups in the other direction are different, and the pixel units with required quantity can be formed by combining the arrangement mode, so that the quantity of the pixel units in unit area is increased, and the resolution of the display panel is further increased, and the resolution of the display panel can be increased without increasing the preparation difficulty.
For example, as shown in fig. 1, the first subpixel group 110 and the second subpixel group 120 have a hexagonal shape including a hollow region, the third subpixel group 130 filling the hollow region of the first subpixel group 110 and the second subpixel group 120 has a diamond shape, two opposite vertices of the third subpixel group 130 disposed in the first subpixel group 110 coincide with two opposite vertices of the first subpixel group 110, two opposite vertices of the third subpixel group 130 disposed in the second subpixel group 120 coincide with two opposite vertices of the second subpixel group 120, and the adjacent subpixels have the same light emission color along the column direction, so that four subpixels of two adjacent first subpixel groups 110 are gathered to form a "four-pointed star" region, which can be printed or evaporated together, and four subpixels of two adjacent second subpixel groups 120 are gathered together, forming regions of "four-pointed star" which may be printed or evaporated together.
The present invention also provides a method of making the above-described pixel structure 10, comprising the steps of: the pixel arrangement structure is prepared by adopting an evaporation process, and specifically comprises the following steps:
preparing a first sub-pixel group, a second sub-pixel group and a third sub-pixel group in a plurality of repeating units by using a first mask plate, a second mask plate and a third mask plate respectively; the opening shape of the first mask corresponds to the shape of the first sub-pixel group, the opening shape of the second mask corresponds to the shape of the second sub-pixel group, and the opening shape of the third mask corresponds to the shape of the third sub-pixel group. For example: when the first sub-pixel group and the second sub-pixel group are hexagons including a hollow region, and the third sub-pixel group filled in the hollow region of the first sub-pixel group and the second sub-pixel group is rhombus, the first mask plate and the second mask plate can respectively adopt the mask plates shown in fig. 4 and 5 (wherein black represents a metal covering region, and white represents an opening region) through combination with adjacent repeating units, compared with the conventional mask plate, the mask plate has the advantages of larger opening area, lower preparation difficulty, smaller stress, longer service life, and the third mask plate can adopt the mask plate shown in fig. 6 (wherein black represents a metal covering region, and white represents an opening region), and the opening size can be adjusted according to requirements.
It is understood that the deposition order of the first sub-pixel group, the second sub-pixel group, and the third sub-pixel group is not particularly limited.
The invention also provides a mask plate group, which comprises a first mask plate, a second mask plate and a third mask plate, wherein the opening of the first mask plate corresponds to the arrangement position and the shape of the first sub-pixel group in the pixel arrangement structure; the opening of the second mask plate corresponds to the arrangement position and the shape of the second sub-pixel group in the pixel arrangement structure; the openings of the third mask correspond to the arrangement position and shape of the third sub-pixel group in the pixel arrangement structure.
The invention also provides a driving method of the pixel arrangement structure, wherein the pixel arrangement structure is the pixel arrangement structure, and the step is particularly limited.
Specifically, the driving method includes the steps of: and controlling the number of the sub-pixels which start to emit light in the first sub-pixel group, the second sub-pixel group and the third sub-pixel group. Since each sub-pixel group in the pixel arrangement structure is composed of a plurality of sub-pixels with the same light-emitting color, the number of sub-pixels needing to emit light can be adjusted through an algorithm, and then the gray scale can be adjusted. Compared with the traditional method for changing the gray scale according to the condition of the sub-pixel luminous brightness, the method is easier to operate and more accurate to adjust.
For example: the gray scale can be divided into 2-4 levels, and when the lower gray scale is needed to be displayed (darker), only one sub-pixel color in a single color area is used for displaying the color. When a higher gray scale display is required (brighter), a plurality of sub-pixels in a single color area are activated to increase the brightness, so as to achieve the high gray scale display.
The present invention also provides a light emitting device, as shown in fig. 7, including a substrate 20 and a pixel defining layer 40.
The pixel defining layer 40 is stacked on the substrate, and forms a pixel pit corresponding to each sub-pixel group of the pixel arrangement structure. Further, the light emitting device may further include a pixel electrode 30, the pixel electrode 30 is disposed on the substrate 20, and the pixel defining layer 40 covers a portion of the pixel electrode 30.
The method and material for manufacturing the substrate 20, the pixel electrode 30 and the pixel defining layer 40 according to the present invention may be any conventional method and material, and are not particularly limited herein. The pixel arrangement structure adopts the above-mentioned pixel arrangement structure, and details thereof are not described herein. It can be understood that the sub-pixels of the pixel arrangement structure correspond to the light emitting units, and are used for emitting light of various colors, and further combined into light of a desired color, and the material forming each sub-pixel is not particularly limited, and can be selected according to the light emitting color.
In one embodiment, the pixel defining layer 40 includes a first pixel defining layer 41 and a second pixel defining layer 42, the second pixel defining layer 42 is stacked on a portion of the first pixel defining layer 41, the second pixel defining layer 42 is used for forming a region corresponding to each sub-pixel group corresponding to the pixel arrangement, and the first pixel defining layer 41 is used for forming a region corresponding to each sub-pixel having the same light emitting color in each pixel group. Therefore, the deposition area of the ink can be effectively enlarged, and the printing process preparation of the high-resolution display is realized.
Understandably, the second pixel defining layer is used for surrounding areas of sub-pixel groups with different light-emitting colors of the pixel arrangement structure, and the first pixel defining layer is used for forming areas corresponding to sub-pixels with the same light-emitting color in the same pixel group, so that the forming areas are determined according to the pixel arrangement structure.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
