Description

Technical Field

[0001] The utility model belongs to the technical field of display elements, and in particular relates to a pixel arrangement structure, a display panel and a display device. Background Art

[0002] Display screens are important human-computer interaction media. From smart watches / bracelets to mobile phones, computers, and dedicated service terminals, to large display screens for displays, conference displays, advertising screens and other smart devices, all need to use display screens as human-computer interaction media. In the existing technology, commonly used display screens mainly have two technical routes: LCD and OLED. In addition, MiniLED and Micro LED display technologies are also developing rapidly. For large display screens, LED display technology is used.

[0003] Display screens generally use RGB as a group of pixels to achieve small-pitch displays (pixel pitch Pitch ≤ 2.5mm). There are two ways to package such displays. The first way is to use traditional packaging and SMD patch methods to complete the packaging of LED display panels, while the second way is to use chip on board packaging technology (Chip on Board) to flip-chip bonding of R, G, B mini chips on the PCB board, and then use compression molding or film bonding to complete the packaging of the display module.

[0004] At present, high-density small-pitch LED, Mini LED, and Micro LED display technologies have all become hot technologies for new high-density LED display screens. The pixel arrangement structure has a decisive influence on the brightness, response speed, color quality, and service life of the display screen. In order to increase the pixel arrangement density, the industry has adopted virtual pixel technology. Virtual pixels use software algorithms to control the light-emitting chips of each color to act as sub-pixels and ultimately participate in the imaging of multiple adjacent pixels, so that a larger resolution can be achieved with fewer lamps, thereby improving the display resolution of multiplexed pixels to a certain extent through sub-pixel multiplexing.

[0005] However, in the prior art, structures such as the standard RGB arrangement, RGBW arrangement, and "diamond arrangement" are all typical pixel arrangement structures, but these pixel arrangement structures all have the problem that the number of times the self-pixels participate in multiplexing is small, resulting in a low pixel multiplexing rate and a low display resolution.

[0006] Therefore, there is an urgent need to provide a pixel arrangement structure, a display panel and a display device that can improve pixel reuse rate and display resolution. Utility Model Content

[0031] refer to Figures 1 to 7As an object of the present invention, a pixel arrangement structure is provided, which includes a plurality of repeated pixel units 10 arranged in a matrix form, and each repeated pixel unit 10 includes a first sub-pixel 11, two second sub-pixels 12 and a third sub-pixel 13. The centers of the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 are respectively located at the four vertices of a square. It should be noted that the square can be a rectangle or a square. In the present invention, the square is used as an example for explanation. The Y direction and the X direction in the figure respectively show the first direction and the second direction. The two opposite sides of the square are parallel along the first direction Y and the second direction X perpendicular to the first direction Y. A plurality of repeated pixel units 10 are arranged in alignment with each other along a first direction Y and a second direction X, respectively, and a square first pixel group 20, a square second pixel group 30, a square third pixel group 40 and a square fourth pixel group 80 are formed between the plurality of repeated pixel units 10. The first pixel group 20 and the second pixel group 30 both include a plurality of sub-pixels arranged in three rows and three columns. A first sub-pixel 11 or a third sub-pixel 13 is correspondingly provided at the center of the first pixel group 20 or the second pixel group 30. Each first sub-pixel 11 at the center can form a plurality of virtual pixel units with a second sub-pixel 12 and a third sub-pixel 13 that are adjacent to each other in the first direction Y and the second direction X, respectively. Each third sub-pixel 13 at the center can form a plurality of virtual pixel units with a first sub-pixel 11 and a second sub-pixel 12 that are adjacent to each other in the first direction Y and the second direction X, respectively. That is to say, each of the first sub-pixels 11 and each of the third sub-pixels 13 mentioned above, which are multiplexed to form multiple virtual pixel units, should be located at the center and other sub-pixels are arranged around it in the first direction Y and the second direction X. Moreover, it should be understood that the virtual pixel unit corresponds to the corresponding first sub-pixel 11 or third sub-pixel 13 being split into multiple pixels for use in a real-time multiplexing manner. The adjacent described in the specification refers to the adjacent position relationship between a sub-pixel located at the center and the other two different sub-pixels with the shortest distance from it. Therefore, the pixel arrangement structure of the utility model can form multiple virtual pixel units by using the first sub-pixel 11 and the adjacent second sub-pixel 12 and the third sub-pixel 13, or / and by using the third sub-pixel 13 and the adjacent first sub-pixel 11 and the second sub-pixel 12, so that more virtual pixel units can be formed, especially compared with typical pixel arrangement structures such as standard RGB arrangement and RGBW arrangement, thereby improving both the pixel multiplexing rate and the display resolution.

[0032] Please refer to further Figure 2 and Figure 5Specifically, a first sub-pixel 11 is disposed at the center of the first pixel group 20, a third sub-pixel 13 is disposed at each of the four vertices of the first pixel group 20, a second sub-pixel 12 is disposed at each of the midpoints of the sides of the first pixel group 20, and Figure 2 In the figure, the first sub-pixel 11 is connected with the second sub-pixel 12 and the third sub-pixel 13 adjacent thereto to form 8 first virtual pixel units: 51, 52, 53, 54, 55, 56, 57, 58, which are arranged in a real-time multiplexing manner. Specifically, a first pixel group 20 is divided into 8 first virtual pixel units 51, 52, 53, 54, 55, 56, 57, 58 that implement pixel multiplexing in the form of right-angled triangles, which reuse a first sub-pixel 11 located at the lower left corner of the physical pixel unit 10. The reuse of other first sub-pixels 11 can be obtained by reference. Therefore, on the basis of a reasonable pixel arrangement structure, a higher pixel reuse rate is obtained, and then a higher display resolution is obtained, thereby providing a display module with a reasonably arranged virtual pixel structure to obtain a better display resolution than a physical pixel structure.

[0033] Please refer to the following for further reference Figure 3 and Figure 6 Specifically, a third sub-pixel 13 is disposed at the center of the second pixel group 30, a first sub-pixel 11 is disposed at each of the four vertices of the second pixel group 30, a second sub-pixel 12 is disposed at each of the midpoints of the sides of the second pixel group 30, and Figure 3 In the figure, the third sub-pixel 13 is connected with the first sub-pixel 11 and the second sub-pixel 12 adjacent thereto to form a plurality of second virtual pixel units: 61, 62, 63, 64, 65, 66, 67, 68. The second virtual pixel unit is obtained by real-time multiplexing. Specifically, a second pixel group 30 is divided into 8 second virtual pixel units for realizing pixel multiplexing in the form of right-angled triangles: 61, 62, 63, 64, 65, 66, 67, 68, which reuses a third sub-pixel 13 located at the upper right corner of the physical pixel unit 10. The reuse of other third sub-pixels 13 can be obtained by reference, so that a higher pixel reuse rate and a higher display resolution can be obtained.

[0034] Please refer to the following for further reference Figure 4 and Figure 7, further preferably, a square third pixel group 40 and a square fourth pixel group 80 are formed between the multiple repeated pixel units 10, and the third pixel group 40 and the fourth pixel group 80 both include multiple sub-pixels arranged in three rows and three columns, and a second sub-pixel 12 is respectively provided at the center and four vertices of the third pixel group 40 and the fourth pixel group, and for each pair of opposite side edges of the third pixel group 40 along the first direction Y and the second direction X, a pair of first sub-pixels 11 and a pair of third sub-pixels 13 are respectively provided at the midpoint of each pair of side edges, and for each pair of opposite side edges of the fourth pixel group 80 along the first direction Y and the second direction X, a pair of third sub-pixels 13 and a pair of first sub-pixels 11 are respectively provided at the midpoint of each pair of side edges, that is, the second sub-pixel 12, which is multiplexed to form multiple virtual pixel units, should be located at the center and other sub-pixels are arranged around it in the first direction Y and the second direction X. Figure 4 In the figure, the second sub-pixel 12 located at the center of the third pixel group 40 is connected by dotted lines to form multiple third virtual pixel units: 71, 72, 73, 74, which can be formed with the first sub-pixel 11 and the third sub-pixel 13 adjacent thereto. The third virtual pixel unit is obtained by time-division multiplexing. Specifically, a third pixel group 40 is divided into four third virtual pixel units: 71, 72, 73, 74, which realize pixel multiplexing in the form of right triangles, and reuses a second sub-pixel 12 located at the lower right corner of the physical pixel unit 10. The reuse of other second sub-pixels 12 can be obtained by reference, and the second sub-pixel 12 located at the center of the fourth pixel group 40 can form multiple fourth virtual pixel units (not shown) with the first sub-pixel 11 and the third sub-pixel 13 adjacent thereto, which will not be repeated here. Therefore, a higher pixel multiplexing rate and a higher display resolution can be further obtained.

[0035] Please refer to the following for further reference Figures 1 to 4Specifically, a first pixel group 20, a second pixel group 30, a third pixel group 40 and a fourth pixel group 80 are combined to form a square repeated pixel group, and the third pixel group 40 and the fourth pixel group are diagonally arranged in the repeated pixel group. It should be pointed out that, for the diagonally arranged third pixel group 40 and the fourth pixel group 80, the difference in the sub-pixel arrangement between the third pixel group 40 in the upper left corner and the fourth pixel group 80 in the lower right corner is that a pair of first sub-pixels 11 and a pair of third sub-pixels 13 are respectively arranged at the midpoints of two pairs of opposite side edges of the third pixel group 40 in the upper left corner along the first direction Y and the second direction X, while a pair of third sub-pixels 13 and a pair of first sub-pixels 11 are respectively arranged at the midpoints of two pairs of opposite side edges of the fourth pixel group 80 in the lower right corner along the first direction Y and the second direction X. Therefore, the repeated pixel group can simultaneously obtain a plurality of first virtual pixel units, second virtual pixel units, third virtual pixel units and fourth virtual pixel units, each centered on the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13, respectively. Therefore, when the pixel arrangement structure is arranged in a matrix in the form of a repeated pixel group, more different virtual pixel units centered on sub-pixels emitting different color light can be obtained. Therefore, on the basis of improving the pixel reuse rate and the display resolution, a better light mixing effect can be obtained. In addition, since the human eye is more sensitive to green, under the premise that the number of green sub-pixels in the repeated pixel unit 10 is relatively large, the number of pixel reuses of the green sub-pixels is less than the number of pixel reuses of the blue sub-pixels and the red sub-pixels, thereby ensuring that the displayed green is not distorted and improving the viewing comfort of the human eye.

[0036] Please refer to the following for further reference Figure 1 Preferably, a plurality of first parallel straight lines that are parallel to the first direction Y and the second direction X and that are at an angle of 45°, and a plurality of second parallel straight lines that are perpendicular to the first parallel straight lines, respectively, pass through the midpoints of the second sub-pixels 12 in sequence or alternately pass through the first sub-pixels 11 and the third sub-pixels 13, and the distances between the midpoints of two adjacent second sub-pixels 12 and the midpoints of two adjacent first sub-pixels 11 and third sub-pixels 13 are equal. In this way, a virtual pixel unit in the shape of an imaginary equilateral right triangle can be obtained, which can not only improve the pixel reuse rate, but also make the light mixing effect of each physical pixel unit and its sub-pixels better, and can also effectively improve the brightness, response speed, color quality, service life and other performance of the display module using the pixel arrangement structure.

[0037] Please refer to the following for further reference Figures 1 to 4Specifically, the number of the first virtual pixel unit and the second virtual pixel unit are both 8, and the number of the third virtual pixel unit is 4. Therefore, the pixel multiplexing rate is improved, especially compared with the standard RGB arrangement and RGBW arrangement as typical pixel arrangement structures, the pixel multiplexing rate is doubled or tripled.

[0038] Please refer to the following for further reference Figures 5 to 7 Specifically, the first sub-pixel 11, the second sub-pixel 12 and the third sub-pixel 13 emit red, green and blue light respectively. Therefore, the utility model provides a method of splitting the first sub-pixel 11 or the third sub-pixel 13, each emitting red light or blue light and centered, into 8 pixels for use, that is, each is multiplexed by 8 pixels. Specifically, Figure 5 FIG. 2 shows a schematic diagram of the structure of a first pixel group 20, which is centered on a red sub-pixel R and is surrounded by four green sub-pixels G1, G2, G3 and G4, one red sub-pixel R and four blue sub-pixels B1, B2, B3 and B4. Figure 5 The first pixel group 20 shown and the time-division multiplexing can obtain the following pixel splitting: B1-G1-R, B2-G1-R, B1-G2-R, B2-G3-R, B3-G2-R, B3-G4-R, B4-G3-R, B4-G4-R. Figure 6 FIG. 3 shows a schematic diagram of the structure of a second pixel group 30, which is centered on a blue light sub-pixel B and around which four red light sub-pixels R1, R2, R3 and R4 and four green light sub-pixels G1, G2, G3 and G4 are arranged. Figure 6 The second pixel group 30 and time-division multiplexing shown can obtain the following pixel splitting: R1-G1-B, R2-G1-B, R1-G2-B, R2-G3-B, R3-G2-B, R3-G4-B, R4-G3-B, R4-G4-B. In addition, it is provided that each sub-pixel emitting green light and centered is split into 4 pixels for use, that is, it is multiplexed by 4 pixels. Specifically, Figure 7 FIG. 4 shows a schematic diagram of the structure of a third pixel group 40, which is centered on a green sub-pixel G and around which four green sub-pixels G1, G2, G3 and G4, two red sub-pixels R1 and R2 and two blue sub-pixels B1 and B2 are arranged. Figure 7 The third pixel group 40 and time-division multiplexing shown can obtain the following pixel divisions: B1-R1-G, B2-R1-G, B1-R2-G, B2-R2-G. Therefore, the display resolution is improved without increasing the number of sub-pixels.

In addition, each sub-pixel preferably adopts LED, and the dividing lines, midpoint lines and division boundaries of repeated pixel units, pixel groups and virtual pixel units shown in the drawings described in the specification are for the purpose of clear explanation and do not represent the actual physical existence of each technical feature.
