Description

Technical Field

[0001] The utility model belongs to the technical field of display elements, and specifically 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, the display technologies of high-density small-pitch LED, Mini LED, and Micro LED have all become the hot technologies of new high-density LED display screens, and the display effects of the products have also become the focus of common concern of users and the industry. In general, without considering brightness, contrast, stability, and uniformity, the factors that affect the image clarity of high-density LED display screens mainly include image spatial resolution, image display layer resolution, pixel optical crosstalk, pixel edge fusion, etc., among which image spatial resolution is equivalent to the arrangement density of LED pixels in LED display. Therefore, 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 improve 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 as sub-pixels to finally participate in the imaging of multiple adjacent pixels, so that a larger resolution can be achieved with fewer lamps, so that the display resolution of multiplexed pixels can be improved to a certain extent through sub-pixel multiplexing.

[0005] However, in the prior art, on the one hand, the three primary colors of a single pixel color gamut are controlled by only a single light-emitting chip. If a single light-emitting chip fails, there will be obvious color mismatch in the corresponding pixel display, resulting in reduced display resolution and display brightness. On the other hand, the display resolution of the reused pixels of adjacent pixels is still low, and if a light-emitting chip with a small size and low brightness is used due to cost constraints, the display brightness will be reduced.

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

[0033] Pixel Arrangement Structure First Embodiment

[0034] Please refer to Figures 1 to 3In this embodiment, the pixel arrangement structure includes a plurality of repeated pixel units 10, each of which includes a first sub-pixel group 11, a second sub-pixel group 12, and a third sub-pixel group 13. The first sub-pixel group 11, the second sub-pixel group 12, and the third sub-pixel group 13 respectively include N first sub-pixels 111, N second sub-pixels 121, and N third sub-pixels 131. The first sub-pixel 111, the second sub-pixel 121, and the third sub-pixel 131 are all LED chips or OLED chips on the substrate of the display module, and are all capable of displaying a color light. In this embodiment and the second embodiment, the shapes of the first sub-pixel 111, the second sub-pixel 121 and the third sub-pixel 131 are all described by taking a rectangle as an example, but they can also be other shapes such as a parallelogram, a trapezoid, a triangle and a rounded polygon, and they are also within the protection scope of the present utility model. In addition, in the two embodiments, the Y direction and the X direction in the figure respectively represent the first direction and the second direction, and the rectangular first sub-pixel 111, the second sub-pixel 121 and the third sub-pixel 131 are all arranged with their long sides parallel to the second direction X, but in the case of no conflict, they can also be arranged with their long sides parallel to the first direction Y. The repeated pixel unit 10 is in a herringbone shape. The first sub-pixel group 11, the second sub-pixel group 12 and the third sub-pixel group 13 are arranged in three rows along the first direction Y, respectively. In a first plane perpendicular to the first direction Y, the orthographic projection of the second sub-pixel group 12 is located between the two orthographic projections of the first sub-pixel group 11 and the third sub-pixel group 13. In a second plane perpendicular to the first plane, that is, the second plane is parallel to the first direction Y, the orthographic projection of the second sub-pixel group 12 does not overlap with the orthographic projections of the first sub-pixel group 11 and the third sub-pixel group 13, and the orthographic projections of the first sub-pixel group 11 and the third sub-pixel group 13 at least partially overlap. N is an integer greater than or equal to 2, and the luminous colors of the first sub-pixel 111, the second sub-pixel 121 and the third sub-pixel 131 are different from each other. In the present invention, the first sub-pixel 111, the second sub-pixel 121 and the third sub-pixel 131 are each 2 and emit green, red and blue light, respectively, as an example for description. Therefore, since there are more than 2 sub-pixels in each sub-pixel group, that is, the three primary colors of the single-pixel color gamut are controlled by more than one light-emitting chip, it is possible to prevent the adverse situation of obvious color mismatch in the corresponding pixel display caused by the failure of a sub-pixel in any sub-pixel group, which is beneficial to maintaining the display resolution and display brightness without reduction. In addition, by utilizing the arrangement of the relative positions of the sub-pixel groups with more than 2 sub-pixels, the different working modes of the light-emitting chip can be controlled, so that the multiplexed pixels of adjacent pixels can have a higher display resolution and improve the display brightness.

[0035] Please refer to the following for further reference Figure 1Preferably, in the second direction X perpendicular to the first direction Y, each first sub-pixel 111 located in the first column and each third sub-pixel 131 located in the third column are aligned in pairs along the second direction X, that is, in the second plane, the orthographic projections of the first sub-pixel group 11 and the third sub-pixel group 13 completely overlap. Each first sub-pixel 111, each second sub-pixel 121 and each third sub-pixel 131 are arranged in N rows along the second direction X, preferably, the distances between adjacent sub-pixel groups and between adjacent sub-pixels in each sub-pixel group in the first direction Y are equal. In this way, the arrangement of each sub-pixel group and its sub-pixels of the repeated pixel unit 10 is regular and compactly distributed, which can make the light mixing effect of the repeated pixel unit 10 better, thereby reducing the difficulty of color adjustment of the display module and improving the color accuracy of the display module.

[0036] Please refer to further Figure 1 Specifically, in the first plane, the orthographic projection of the second sub-pixel group 12 partially overlaps with the orthographic projection of the first sub-pixel group 11 and the orthographic projection of the third sub-pixel group 13. In this way, the arrangement density of each sub-pixel can be increased, which is also conducive to the pixel multiplexing of at least one corresponding repeated sub-pixel between each pair of adjacent repeated pixel units 10. In addition, the wavelength value difference range of the color light emitted by each sub-pixel in the same sub-pixel group is between 0 and 20nm, wherein when the wavelength value difference range is between 0 and 5nm, the brightness can be improved, and when the wavelength value difference range is between 5 and 20nm, a wider display color gamut can be obtained.

[0037] Please refer to further Figure 2 , further preferably, the pixel arrangement structure further includes a plurality of first mirror image repeating pixel units 10', the first mirror image repeating pixel unit 10' is equivalent to being obtained by mirroring along the first direction Y with the bottom side of the repeating pixel unit 10 located in the first direction Y as the mirror symmetric side, in the second direction X, every two adjacent repeating pixel units 10 and first mirror image repeating pixel units 10' are aligned to form a repeating pixel unit row, and different sub-pixel groups in each repeating pixel unit row are aligned in turn in the second direction X, in the first direction Y, a plurality of repeating pixel units 10 and a plurality of first mirror image repeating pixel units 10' are respectively aligned to form a repeating pixel unit column and a first mirror image repeating pixel unit column, the same sub-pixel group in each repeating pixel unit column is aligned in the first direction Y, and the same sub-pixel group in each first mirror image repeating pixel unit column is aligned in the first direction Y, for example, Figure 2 and 3As shown, along the second direction X, each first sub-pixel group 11 in the first repeated pixel unit column has two identical sub-pixel groups and is aligned in the first direction Y to form a first sub-pixel group column, each second sub-pixel group 12 also has two identical sub-pixel groups and is aligned in the first direction Y to form a second sub-pixel group column, the first sub-pixel group column and the second sub-pixel group column are respectively located in the first column and the second column in the second direction X, and so on. Each first sub-pixel group 11 in the first first mirror image repeated pixel unit column adjacent to the first repeated pixel unit column in the second direction X has two identical sub-pixel groups and is aligned in the first direction Y to form a first sub-pixel group column, each second sub-pixel group 12 also has two identical sub-pixel groups and is also aligned in the first direction Y to form a second sub-pixel group column, the first sub-pixel group column and the second sub-pixel group column are respectively located in the fourth column and the fifth column in the second direction X, and so on. For the repeated pixel units 10 and the first mirrored repeated pixel units 10' that are adjacent to each other in the second direction X, at least one third sub-pixel 131 in the third sub-pixel group 13 in the repeated pixel unit 10 located relatively upstream and at least one second sub-pixel 121 in the second sub-pixel group 12 in the first mirrored repeated pixel unit 10' located relatively downstream can be used for pixel multiplexing, that is, by controlling the lighting coordination of at least one third sub-pixel 131 in the third sub-pixel group 13 and at least one sub-pixel adjacent to it and coming from the repeated pixel unit 10 and the first mirrored repeated pixel unit 10' and emitting one of the other two color lights, the purpose of multiplexing the sub-pixels in the repeated pixel unit 10 can be achieved, and a virtual resolution that is multiple of the physical resolution can be obtained. It should be noted that, if Figure 2 As shown, the repeated pixel units 10 and the first mirrored repeated pixel units 10' adjacent to each other in the second direction X obtain three virtual pixel units 14a, 14b, 14c shown in the dotted box by multiplexing at least one third sub-pixel 131 and at least one second sub-pixel 121. Alternatively, for the repeated pixel units 10 or the first mirrored repeated pixel units 10' adjacent to each other in the first direction Y, at least one first sub-pixel 111 in the first sub-pixel group 11 and at least one third sub-pixel 131 in the three sub-pixel group in a repeated pixel unit 10 located relatively upstream can be used for pixel multiplexing of the repeated pixel units 10 adjacent to each other in the first direction Y, as shown in FIG. Figure 3As shown, two virtual pixel units 14d and 14e shown in the dashed box are obtained by pixel multiplexing at least one first sub-pixel 111 and at least one third sub-pixel 131 of the repeated pixel unit 10 located relatively upstream in the first direction Y. For the first mirrored repeated pixel units 10' adjacent to each other in the first direction Y, at least one second sub-pixel 121 in the second sub-pixel group 12 in a first mirrored repeated pixel unit 10' located relatively upstream can be used for pixel multiplexing. Figure 3 As shown, two virtual pixel units 14f and 14g shown in the dotted box are obtained by multiplexing the pixels of at least one second sub-pixel 121 of the repeated pixel units 10 that are adjacent to each other in the first direction Y. In addition, it should be noted that other virtual pixel units can also be obtained in this embodiment. Only some of the obtaining methods are described here, and other obtaining methods can be obtained by reference. For the above-mentioned pixel multiplexing method, it is particularly suitable for smaller-sized light-emitting chips as sub-pixels, thereby reducing the cost of light-emitting chips. In summary, since multiple virtual pixel units can be obtained, the display resolution can be improved. Moreover, even if a single sub-pixel in a sub-pixel group fails, since there is at least one identical other sub-pixel in the corresponding sub-pixel group, it will not cause a certain color light to fail to display, thereby reducing the possibility of rework caused by the failure of only a single sub-pixel in a certain sub-pixel group in the prior art.

[0038] Second Embodiment of Pixel Arrangement Structure

[0039] Please refer to Figure 4 and Figure 5In this embodiment, the technical contents that are the same or similar to those in the first embodiment of the pixel arrangement structure are not described in detail here, and please refer to the above. The pixel arrangement structure of this embodiment includes a plurality of repeated pixel units 20, each of which includes a first sub-pixel group 21, a second sub-pixel group 22, and a third sub-pixel group 23. The first sub-pixel group 21, the second sub-pixel group 22, and the third sub-pixel group 23 include N first sub-pixels 211, N second sub-pixels 221, and N third sub-pixels 231, respectively. The first sub-pixel group 21, the second sub-pixel group 22 and the third sub-pixel group 23 are arranged in three rows along the second direction X, respectively. In a first plane perpendicular to the second direction X, the orthographic projection of the first sub-pixel group 21 overlaps with the orthographic projection of the third sub-pixel group 23 at least partially, and the orthographic projection of the second sub-pixel group 22 does not overlap with the orthographic projections of the first sub-pixel group 21 and the third sub-pixel group 23, respectively. In a second plane perpendicular to the first plane, the orthographic projections of the first sub-pixel group 21, the second sub-pixel group 22 and the third sub-pixel group 23 do not overlap. N is an integer greater than or equal to 2, and the luminous colors of the first sub-pixel 211, the second sub-pixel 221 and the third sub-pixel 231 are different from each other. Therefore, for the arrangement of the relative positions of each repeated pixel unit 20 and its sub-pixel group, when obtaining a virtual pixel, since there are more than 2 sub-pixels in each sub-pixel group, when one or two sub-pixel groups are used as multiplexing units to realize sub-pixel multiplexing, a higher display resolution of one or more times can be obtained at the same size, and the unfavorable situation of obvious color mismatch on the display of the corresponding pixel caused by the failure of a certain sub-pixel in any sub-pixel group can be prevented, which is conducive to maintaining the display resolution and display brightness without reduction. In addition, when selectively controlling the different sub-pixels in the sub-pixel groups that emit the same color light in some or all repeated pixel units 20, the display brightness can be improved to meet the brightness requirements of specific places.

[0040] Please refer to further Figure 4 Preferably, in the first direction Y perpendicular to the second direction X, each first sub-pixel 211 in the first row and each third sub-pixel 231 in the third row are aligned in pairs along the second direction X, that is, the orthographic projection of the first sub-pixel group 21 overlaps with the orthographic projection of the third sub-pixel group 23. Each first sub-pixel 211, each second sub-pixel 221 and each third sub-pixel 231 are arranged in N columns along the first direction Y. Preferably, the spacing between each adjacent sub-pixel group in the first direction Y is equal, and the spacing between each adjacent sub-pixel in each sub-pixel group in the first direction Y is equal. In this way, the arrangement of each sub-pixel group and its sub-pixels of the repeated pixel unit 20 is regular and compact, which can make the light mixing effect of the repeated pixel unit 20 better, thereby reducing the difficulty of color adjustment of the display module and improving the color accuracy of the display module.

[0041] Please refer to the following for further reference Figure 5 , further preferably, the pixel arrangement structure further includes a plurality of second mirror image repeating pixel units 20', the second mirror image repeating pixel units 20' being equivalent to being obtained by mirroring along the second direction X with the front side or the rear side of the repeating pixel unit 20 located in the second direction X as the mirror image symmetric edge, in the first direction Y, every two adjacent repeating pixel units 20 and second mirror image repeating pixel units 20' are aligned and arranged into repeating pixel unit columns, and different sub-pixel groups of each repeating pixel unit column are aligned and arranged alternately in the first direction Y in turn, in the second direction X, a plurality of repeating pixel units 20 and a plurality of second mirror image repeating pixel units 20' are aligned and arranged respectively to form alternating repeating pixel unit rows and second mirror image repeating pixel unit rows, and the same sub-pixel groups in each repeating pixel unit row and the second mirror image repeating pixel unit row are aligned and arranged in the second direction X. For example, if Figure 5 As shown, along the second direction X, the first repeated pixel unit column is aligned with different sub-pixel groups of the first sub-pixel group 21, the third sub-pixel group 23 and the second sub-pixel group 22, and the second repeated pixel unit column is aligned with different sub-pixel groups of the second sub-pixel group 22, the first sub-pixel group 21 and the third sub-pixel group 23, and so on. Along the first direction Y, all the first sub-pixel groups 21, all the second sub-pixel groups 22 and all the third sub-pixel groups 23 in the first repeated pixel unit row are aligned in the second direction X to form the first sub-row, the second sub-row and the third sub-row. All the first sub-pixel groups 21, all the second sub-pixel groups 22 and the third sub-pixel group 23 in the first second mirror image repeated pixel unit row below the first repeated pixel unit row are aligned in the second direction X to form the fourth sub-row, the fifth sub-row and the sixth sub-row. And so on.

[0042] For the repeated pixel units 20 and the second mirrored repeated pixel units 20' adjacent to each other in the first direction Y, at least one third sub-pixel 231 in the third sub-pixel group 23 in the repeated pixel unit 20 located relatively upstream can be used for pixel multiplexing of the repeated pixel units 20 adjacent to each other in the first direction Y, such as Figure 5 As shown, the two virtual pixel units 24a and 24b shown in the dashed line frame are obtained by multiplexing at least one third sub-pixel 231 in the repeated pixel units 20 adjacent to each other in the first direction Y. Alternatively, for the repeated pixel units 20 adjacent to each other in the second direction X or the second mirrored repeated pixel units 20' adjacent to each other in the second direction X, at least one second sub-pixel 221 in the second sub-pixel group 22 in the repeated pixel unit 20 located relatively upstream can be used for pixel multiplexing, as shown in FIG. Figure 5As shown, two virtual pixel units 24a and 24c shown in the dashed line frame are obtained by multiplexing at least one second sub-pixel 221 in the second direction X. Alternatively, at least one first sub-pixel 211 in the first sub-pixel group 21 and at least one third sub-pixel 231 in the third sub-pixel group 23 in the second mirror-image repeated pixel unit 20' can be used for pixel multiplexing, such as Figure 5 As shown, in the second direction X, two virtual pixel units 24d and 24e shown in the dashed line frame are obtained by multiplexing at least one first sub-pixel 211 and at least one third sub-pixel 231. In addition, it should be noted that other virtual pixel units can also be obtained in this embodiment. For example, two virtual pixel units 24a and 24f shown in the dashed line frame are obtained by multiplexing at least one second sub-pixel 221 and at least one third sub-pixel 231 in the repeated pixel units 20 adjacent to each other in the first direction Y. Therefore, only part of the obtaining method is described here, and other obtaining methods can be obtained by reference. In summary, since the sub-pixels in each sub-pixel group can be selectively turned on, multiple virtual pixel units can be obtained, thereby improving the display resolution, and even if a sub-pixel in a sub-pixel group fails, since there is at least one identical other sub-pixel in the corresponding sub-pixel group, it will not cause a certain color light to fail to display, thereby reducing the possibility of rework caused by the failure of only a single sub-pixel in a sub-pixel group in the prior art.

[0043] Further preferably, the first sub-pixel group 21, the second sub-pixel group 22 and the third sub-pixel group 23 adjacent to each other in pairs respectively have a first sub-pixel 211, a second sub-pixel 221 and a third sub-pixel 231 located in the same position in the second direction X and are combined in the first direction Y to form a sub-pixel unit 25, such as Figure 4 and Figure 5 As shown, the triangles formed by the dashed lines represent the sub-pixel units 25. Each individual repeated pixel unit 20 or the repeated pixel units 20 and the second mirror image repeated pixel units 20' adjacent to each other in the first direction Y include N sub-pixel units 25. It can be seen that the number of sub-pixel units 25 is equal to the number of sub-pixels in the sub-pixel group, and the N sub-pixel units 25 are controlled to work simultaneously or two or more sub-pixels corresponding to the same one or two sub-pixel groups in the N sub-pixel units 25 are controlled to work simultaneously. When the N sub-pixel units 25 are controlled to work simultaneously, the display resolution is doubled through pixel multiplexing. When one or two of the first sub-pixel group 21, the second sub-pixel group 22 and the third sub-pixel group 23 arranged along the second direction X in the N sub-pixel units 25 are controlled to work simultaneously, the display brightness can be improved to meet the brightness requirements of a specific place.
