Description

Technical Field

[0001] The present invention 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, standard RGB arrangement, RGBW arrangement, etc. are all typical pixel arrangement structures, but these pixel arrangement structures all have the problem that the number of times sub-pixels participate in multiplexing is small, resulting in 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 display resolution. Summary of the invention

In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. Moreover, the term "include", "comprise" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such a process, method, article or device.

If there is no conflict, the embodiments of the present invention and the various features in the embodiments can be combined with each other, all within the protection scope of the present invention.

[0042] As an object of the present invention, a pixel arrangement structure is provided, which is applied to a display module and includes a plurality of physical pixel units arranged in an array and in a parallelogram shape, each physical pixel unit includes a first sub-pixel, a second sub-pixel and a third sub-pixel, and the sum of the three sub-pixels is 2N, N≥2 and is a natural number, and in the following embodiments, N=2, 4 or 12 are respectively used as examples for detailed description, so for N being other specific numerical values, it can be obtained by reference without contradiction, and all are within the protection scope of the present invention.

Since the plurality of physical pixel units of the pixel arrangement structure are in a parallelogram shape and have a total of 2N sub-pixels, each of four adjacent and three different sub-pixels can form a virtual pixel unit, so that the number of times the sub-pixels participate in multiplexing is large, which can improve the display resolution.

[0043] The pixel arrangement structure provided by the present invention is described in detail below in conjunction with multiple embodiments of the pixel arrangement structure.

[0044] Pixel Arrangement Structure First Embodiment

[0045] Please refer to Figure 1 and Figure 2 The physical pixel unit 10 includes a first physical pixel unit 101, and the N corresponding to the first physical pixel unit 101 is 2. The first physical pixel unit is rectangular. It is known that the rectangle is a square such as a long rectangle or a square. In the first physical pixel unit 101, 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 rectangle, and in the first direction Y, a first sub-pixel 11 and a third sub-pixel 13 are aligned and arranged in the first column, and two second sub-pixels 12 are aligned and arranged in the second column. In the second direction X perpendicular to the first direction Y, a first sub-pixel 11 and a second sub-pixel 12 are aligned and arranged in the first row, and a third sub-pixel 13 and a second sub-pixel 12 are aligned and arranged in the second row. It should be noted that each first physical pixel unit 101 is controlled as a minimum control unit as a whole to perform scanning drive.

[0046] During display, the sub-pixels in the pixel arrangement structure are multiplexed to form various display pixels or pixel points of the display device. Specifically, in the first direction Y, four three different sub-pixels that are adjacent to each other and arranged in a rectangular shape between two adjacent first physical pixel units 101 form a virtual pixel unit 14. For example, Figure 1 A third sub-pixel 13 and a second sub-pixel 12 located at the upper side of the rectangle of the virtual pixel unit 14 are reused, so that in the first direction Y, the virtual pixel unit 14 located at the lower side of a first physical pixel unit 101 displays the pixel of the second row and the first column of the picture by multiplexing the third sub-pixel 13 and the second sub-pixel 12. In the second direction X, four three different sub-pixels that are adjacent in sequence and arranged in a rectangular shape between two adjacent physical pixel units 10 form a virtual pixel unit 14, for example, Figure 1The two second sub-pixels 12 located at the right side of the rectangle of the virtual pixel unit 14 are reused, so that in the second direction X, a first physical pixel unit 101 located on the relatively left side displays the pixels of the first row and the first column of the picture, and the virtual pixel unit 14 located on the right side of the first physical pixel unit 101 displays the pixels of the first row and the second column of the picture by reusing the two second sub-pixels 12. In addition, for example, in the second direction X, the second sub-pixel 12 of the second row and the second column of the first physical pixel unit 101 located on the upstream side and the third sub-pixel 13 of the second row and the first column of the first physical pixel unit 101 located on the downstream side of two adjacent first physical pixel units 101 can also be reused as the upper side of the rectangle of a virtual pixel unit 14 located under them. Therefore, the description of the virtual pixel unit in each embodiment of the specification of the present invention satisfies the requirements for forming a virtual pixel unit as long as four and three different adjacent sub-pixels can realize pixel reuse to form a virtual pixel point, and therefore, it is not limited to the different sub-pixels arranged in a specific direction as specifically described in this specification to form a virtual pixel unit.

[0047] The following combination Figure 2 The control mode of the display device having a pixel arrangement structure with a plurality of first physical pixel units 101 is described in detail. Figure 2 In the figure, H represents the row tube of the driver IC, L represents the column tube of the driver IC, and H1, H2, H3, H4, H5, and H6 are connected to the common poles of the sub-pixels of the corresponding LED in the row. The display of the picture is realized by scanning display. Different from the single-row progressive scanning of the conventional display screen, the present embodiment adopts double-row progressive incremental scanning. For example, at the first moment, the row tubes H1 and H2 channels are turned on, and the other channels are turned off. At this time, the output of each column tube L is controlled to display the first row of pixel information of the picture; at the second moment, the H2 and H3 channels are turned on, and the other channels are turned off. At this time, the output of each column tube L is controlled to display the second row of pixel information of the picture; and so on. Therefore, the display drive control of the 4-subpixel repeating structure is realized, and the corresponding sub-pixels in each virtual pixel unit are reused.

[0048] Therefore, the pixel arrangement structure of this embodiment can form multiple rectangular virtual pixel units 14, and each sub-pixel participates in multiplexing more times, thereby improving the display resolution. Furthermore, while obtaining the same display resolution, the total number of sub-pixels can be reduced, thereby reducing costs.

[0049] Please refer to Figure 3, further improved, the physical pixel unit 10 also includes a second physical pixel unit 102 in a rectangular shape, and the N corresponding to the second physical pixel unit 102 is 2. For the second physical pixel unit 102, compared with the first physical pixel unit 101, the positions of a first sub-pixel 11 and a third sub-pixel 13 located in the first column in the first physical pixel unit 101 are swapped. Specifically, in the second physical pixel unit 102, 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 the second physical pixel unit 102, and in the first direction Y, a third sub-pixel 13 and a first sub-pixel 11 are aligned and arranged in sequence to form a first column, and two second sub-pixels 12 are aligned and arranged in a second column. In the second direction X perpendicular to the first direction Y, a third sub-pixel 13 and a second sub-pixel 12 are aligned and arranged in sequence to form a first row, and a first sub-pixel 11 and a second sub-pixel 12 are aligned and arranged in a second row. The first physical pixel unit 101 and the second physical pixel unit 102 are aligned with each other in the second direction X to form a basic regular unit. Similar to the scanning drive control of the first physical pixel unit 101 described above, each basic regular unit is controlled as a minimum control unit for scanning drive as a whole, and multiple basic regular units are aligned and arranged end to end in the first direction Y and the second direction X. During display, the sub-pixels in the pixel arrangement structure are reused to form each display pixel of the display device. Specifically, in each basic regular unit, four adjacent and rectangularly arranged three different sub-pixels between adjacent first physical pixel units 101 and second physical pixel units 102 form a virtual pixel unit 14, and each virtual pixel unit 14 reuses two second sub-pixels 12 located in the second column of the first physical pixel unit 101. In the first direction Y, four adjacent and rectangularly arranged three different sub-pixels between two adjacent basic regular units form a virtual pixel unit 14. For example, Figure 3 As shown, for each basic regular unit located on the upstream side, a third sub-pixel 13 and a second sub-pixel 12 located in the second row in the first physical pixel unit 101, a first sub-pixel 11 and a second sub-pixel 12 located in the second row in the second physical pixel unit 102, and a second sub-pixel 12 located in the second row in the first physical pixel unit 101 and a first sub-pixel 11 located in the second row in the second physical pixel unit 102 can all be reused. Therefore, the pixel arrangement structure of this embodiment enables different sub-pixels to be reused in the first direction Y and the second direction X, thereby increasing the number of times sub-pixels participate in reuse, which is beneficial to improving display resolution.

[0050] The following combination Figure 4The control mode of the display device having a pixel arrangement structure with a plurality of basic regular units is described in detail, which is similar to the control mode of the display device having a pixel arrangement structure with a plurality of first physical pixel units 101. Figure 4 In the figure, H represents the row tube of the driver IC, L represents the column tube of the driver IC, and H1, H2, H3, H4, H5, and H6 are connected to the common poles of the sub-pixels of the corresponding LED in the row. The display of the picture is achieved by scanning display. For example, at the first moment, the row tubes H1 and H2 channels are turned on, and the other channels are turned off. At this time, the outputs of the column tubes L are controlled to display the pixel information of the first row of the picture; at the second moment, the H2 and H3 channels are turned on, and the other channels are turned off. At this time, the outputs of the column tubes L are controlled to display the pixel information of the second row of the picture; and so on. Therefore, the display drive control of the 8-subpixel repeating structure is realized. In addition, it should be noted that the following display drive control method for each pixel arrangement structure can refer to the above Figure 2 and Figure 4 This is achieved by combining the specific settings of the virtual pixel unit.

[0051] Second embodiment of pixel arrangement structure

[0052] Please refer to Figure 5 and Figure 6 , the physical pixel unit 20 of the pixel arrangement structure includes a first physical pixel unit 201 or a second physical pixel unit 202, the above-mentioned parallelogram is specifically a rectangle, the first physical pixel unit 201 or the second physical pixel unit 202 corresponds to N is 4, and the centers of the first sub-pixels 21, the second sub-pixels 22 and the third sub-pixels 23 are respectively located at the four vertices of a rectangle and the three equal divisions of the two long sides. Figure 5 As shown, for the first physical pixel unit 201, in the first direction Y, a first sub-pixel 21, a second sub-pixel 22, a first sub-pixel 21 and a third sub-pixel 23 are aligned and arranged in sequence to form a first column, a third sub-pixel 23, a first sub-pixel 21, a third sub-pixel 23 and a second sub-pixel 22 are aligned and arranged in sequence to form a second column, the first column and the second column are calculated along the second direction X, and in the second direction X perpendicular to the first direction Y, a first sub-pixel 21 and a third sub-pixel 23 are aligned and arranged in sequence to form a first row, a second sub-pixel 22 and a first sub-pixel 21 are aligned and arranged in sequence to form a second row, a first sub-pixel 21 and a third sub-pixel 23 are aligned and arranged in sequence to form a third row, a third sub-pixel 23 and a second sub-pixel 22 are aligned and arranged in sequence to form a fourth row, the first row to the fourth row are calculated along the first direction Y. Figure 6As shown, for the second physical pixel unit 202, compared with the first physical pixel unit 201, the first sub-pixel 21 located in the second row and the second column in the first physical pixel unit 201 is replaced by the second sub-pixel 22. In each first physical pixel unit 201 or each second physical pixel unit 202 and between two first physical pixel units 201 or second physical pixel units 202 adjacent to each other in the first direction Y and the second direction X, a virtual pixel unit 24 is formed by combining four sub-pixels adjacent to each other in a rectangular shape parallel to the first direction Y or the second direction X. Therefore, the present embodiment provides two physical pixel units: a first physical pixel unit 201 and a second physical pixel unit 202. Either of the two pixel arrangement structures can achieve the technical effect of improving the sub-pixel multiplexing rate and thus improving the display resolution. When the second sub-pixel 22 emits green primary light, since the second physical pixel unit 202 has one more second sub-pixel 22 than the first physical pixel unit 201, and since the human eye is more sensitive to green, the number of green sub-pixels is larger, which can help ensure that the displayed green is not distorted and improve the comfort of the human eye when viewing.

[0053] Please refer to Figure 7 In a further improvement, the pixel arrangement structure includes a rectangular basic regular unit 25 formed by aligning a first physical pixel unit 201 and a second physical pixel unit 202 adjacent to each other in the second direction X, and the pixel arrangement structure includes a plurality of basic regular units 25 aligned end to end in the first direction Y and the second direction X. In each physical pixel unit of each basic regular unit 25 and between two adjacent basic regular units 25 in the first direction Y and the second direction X, a virtual pixel unit 24 is formed by combining three types of sub-pixels in a number of four and arranged adjacently in a rectangular shape parallel to the first direction Y or the second direction X. For example, in Figure 7 In the embodiment, two virtual pixel units 24 pixel points that are adjacent to each other in the first direction Y or the second direction X respectively reuse two sub-pixels located in the same column or the same row. Therefore, since the basic rule unit 25 includes the first physical pixel unit 201 and the second physical pixel unit 202 at the same time, the form of sub-pixel multiplexing is increased, and the diversity of the scanning drive control method can be increased to a certain extent on the basis of improving the display resolution.

N corresponding to the physical pixel unit 30 is 12. The two first pixel groups 301 are arranged diagonally, and the two second pixel groups 302 are arranged diagonally. The two first pixel groups 301 and the two second pixel groups 302 each include three rows of sub-pixels arranged along the second direction X. In a first direction Y perpendicular to the second direction X, the first row of sub-pixels in the three rows of sub-pixels of the first pixel group 301 sequentially includes a third sub-pixel 33 and a second sub-pixel 32, the second row of sub-pixels sequentially includes a third sub-pixel 33 and a first sub-pixel 31, and the third row of sub-pixels sequentially includes a first sub-pixel 31 and a second sub-pixel 32. In an inclined direction W that forms an angle with both the first direction Y and the second direction X, the first pixel groups 301 are arranged along the inclined direction W into a first column of sub-pixels and a second column of sub-pixels that are equally spaced in the second direction X.

[0056] For the second pixel group 302, compared with the first pixel group 301, the two second sub-pixels 32 in the second column of sub-pixels in the first pixel group 301 are replaced by two first sub-pixels 41, and the one first sub-pixel 31 in the second column of sub-pixels in the first pixel group 301 is replaced by a second sub-pixel 32. Specifically, the first row of sub-pixels in the three rows of sub-pixels in the second pixel group 302 sequentially includes a third sub-pixel 33 and a first sub-pixel 31, the second row of sub-pixels sequentially includes a third sub-pixel 33 and a second sub-pixel 32, and the third row of sub-pixels sequentially includes two first sub-pixels 31.

[0057] In the second direction X, the rows of sub-pixels in the adjacent first pixel group 301 and the second pixel group 302 are aligned, and in the oblique direction W, the columns of sub-pixels in the adjacent first pixel group 301 and the second pixel group 302 are aligned.

[0058] In each physical pixel unit 30 or between each pair of adjacent physical pixel units 30, a virtual pixel unit 34, i.e., a pixel point, is formed by a combination of three sub-pixels of five. The center points of four sub-pixels in the virtual pixel unit 34 coincide with the endpoints of a rectangle parallel to the first direction Y or the second direction X, and another sub-pixel coincides with the center point of the rectangle. Specifically, for example, two virtual pixel units 34 adjacent to each other in the first direction Y and the second direction X respectively reuse two sub-pixels located in the same column and the same row, or / and, in each physical pixel unit 30 or between each pair of adjacent physical pixel units 30, a virtual pixel unit 34 is formed by a combination of three sub-pixels of four and arranged in a rectangle parallel to the tilt direction W. Specifically, for example, Fig. 9As shown, in a specific implementation of the pixel arrangement structure embodiment, two virtual pixel units 34 adjacent to each other in the first direction Y and the second direction X both reuse two sub-pixels, such as Fig.10 As shown, in another specific implementation of the pixel arrangement structure embodiment, two virtual pixel units 34 adjacent to each other in the tilt direction W both reuse two sub-pixels, such as Fig.11 As shown, in another specific implementation of the pixel arrangement structure embodiment, not only two virtual pixel units 34 adjacent to each other in the first direction Y and the second direction X reuse two sub-pixels, but also two virtual pixel units 34 adjacent to each other in the oblique direction W reuse two sub-pixels. Therefore, the pixel arrangement structure embodiment can obtain multiple forms of pixel reuse, so that the number of times of sub-pixel reuse is further relatively increased, which is conducive to further improving the display resolution.
