[0022] Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0024] Please see Figures 1 to 4 The pixel structure 1 provided in this application includes a first sub-pixel 10, a second sub-pixel 20, and a third sub-pixel 30. The first sub-pixel 10 and the third sub-pixel 30 are arranged alternately in both the row and column directions. In two first sub-pixels 10 and two third sub-pixels 30 in adjacent rows and adjacent columns, the line connecting the geometric center of the first sub-pixel 10 and the geometric center of the third sub-pixel 30 is arranged to form an irregular quadrilateral 3. A second sub-pixel 20 is correspondingly disposed in one of the irregular quadrilaterals 3. In any one of the irregular quadrilaterals 3, at least one first sub-pixel 10 and at least one third sub-pixel 30 are provided with a chamfer 40.

[0025] Among them, two first sub-pixels 10 and two third sub-pixels 30 in adjacent rows and adjacent columns, and a corresponding second sub-pixel 20 constitute a specific region 2.

[0026] In this embodiment, by providing a chamfer 40 to at least one of the two first sub-pixels 10 and the two third sub-pixels 30 in adjacent rows and columns, the line connecting the geometric center of the first sub-pixel 10 and the geometric center of the third sub-pixel 30 is arranged into an irregular quadrilateral 3, thereby alleviating the technical problem of color mixing easily occurring between adjacent sub-pixels of different colors in the existing pixel structure 1.

[0027] The technical solution of this application will now be described in conjunction with specific embodiments.

[0028] In one embodiment, the first sub-pixel 10 can be any one of a blue sub-pixel, a green sub-pixel, and a red sub-pixel; the second sub-pixel 20 can be any one of a blue sub-pixel, a green sub-pixel, and a red sub-pixel; and the third sub-pixel 30 can be any one of a blue sub-pixel, a green sub-pixel, and a red sub-pixel. The emission colors of the first sub-pixel 10, the second sub-pixel 20, and the third sub-pixel 30 are all different.

[0029] In one embodiment, the second sub-pixel 20 is disposed at the geometric center of the irregular quadrilateral 3.

[0030] It is understandable that setting the second sub-pixel 20 at the geometric center of the irregular quadrilateral 3 can further increase the distance from the second sub-pixel 20 to the four corners of the irregular quadrilateral 3, and reduce the color mixing between the second sub-pixel 20 and the adjacent first sub-pixel 10 and the third sub-pixel 30.

[0031] In this embodiment, by setting the second sub-pixel 20 at the geometric center of the irregular quadrilateral 3, the color mixing between the second sub-pixel 20 and the adjacent first sub-pixel 10 and the third sub-pixel 30 is reduced in any of the irregular quadrilaterals 3.

[0032] In one embodiment, in any of the irregular quadrilaterals 3, at least one of the first sub-pixels 10 is provided with a first chamfer 401, and at least one of the third sub-pixels 30 is provided with a second chamfer 402, wherein the cut area of ​​the first chamfer 401 is not equal to the cut area of ​​the second chamfer 402.

[0033] In one embodiment, please refer to Figure 1 The third sub-pixel 30 is a blue sub-pixel, and the cut area of ​​the second chamfer 402 is greater than the cut area of ​​the first chamfer 401.

[0034] Understandably, for blue subpixels, since blue subpixels have low light emission, increasing the chamfer area of ​​the blue subpixel at a 40° angle further mitigates the risk of color mixing between adjacent subpixels of different colors.

[0035] In this embodiment, the third sub-pixel 30 is a blue sub-pixel, and the cut area of ​​the second chamfer 402 of the blue sub-pixel is larger than the cut area of ​​the first chamfer 401, thereby further reducing the color mixing between the blue sub-pixel and other sub-pixels of different colors.

[0036] In one embodiment, the cut area of ​​the first cut of the first sub-pixel 10 is equal to the cut area of ​​the second cut of the third sub-pixel 30.

[0037] In one embodiment, please refer to Figure 1 The first sub-pixel 10 and the third sub-pixel 30 are arranged in odd-numbered rows and even-numbered rows in the row direction. The first sub-pixel 10 and the third sub-pixel 30 in the odd-numbered rows are provided with chamfered corners 40, and the first sub-pixel 10 and the third sub-pixel 30 in the even-numbered rows are regular quadrilaterals.

[0038] Among them, the first sub-pixel 10 and the third sub-pixel 30 in the even-numbered rows are themselves regular quadrilaterals.

[0039] It is understood that by setting the first sub-pixel 10 and the third sub-pixel 30 in the odd-numbered rows with chamfered corners 40, the geometric centers of the light-emitting areas of the two first sub-pixels 10 and the two third sub-pixels 30 in adjacent rows and adjacent columns can form the irregular quadrilateral 3.

[0040] In one embodiment, please refer to Figure 2 The first sub-pixel 10 and the third sub-pixel 30 are arranged in odd-numbered rows and even-numbered rows in the row direction. The first sub-pixel 10 and the third sub-pixel 30 in the even-numbered rows are provided with chamfered corners 40, and the first sub-pixel 10 and the third sub-pixel 30 in the odd-numbered rows are regular quadrilaterals.

[0041] Among them, the first sub-pixel 10 and the third sub-pixel 30 in the odd-numbered rows are themselves regular quadrilaterals.

[0042] It is understood that by setting the first sub-pixel 10 and the third sub-pixel 30 in the even-numbered rows with chamfered corners 40, the geometric centers of the light-emitting areas of the two first sub-pixels 10 and the two third sub-pixels 30 in adjacent rows and adjacent columns can form the irregular quadrilateral 3.

[0043] In one embodiment, please refer to Figure 3 The first sub-pixel 10 and the third sub-pixel 30 are arranged in an odd-numbered column and an even-numbered column in the column direction. The first sub-pixel 10 and the third sub-pixel 30 in the odd-numbered column are provided with a chamfer 40, and the first sub-pixel 10 and the third sub-pixel 30 in the even-numbered column are regular quadrilaterals.

[0044] Among them, the first sub-pixel 10 and the third sub-pixel 30 of the even-numbered column are themselves regular quadrilaterals.

[0045] It is understood that by setting the first sub-pixel 10 and the third sub-pixel 30 of the odd-numbered columns with chamfered corners 40, the geometric centers of the light-emitting areas of the two first sub-pixels 10 and the two third sub-pixels 30 in adjacent rows and adjacent columns can form the irregular quadrilateral 3.

[0046] In one embodiment, please refer to Figure 4 The first sub-pixel 10 and the third sub-pixel 30 are arranged in an odd-numbered column and an even-numbered column in the column direction. The first sub-pixel 10 and the third sub-pixel 30 in the even-numbered column are provided with a chamfer 40, and the first sub-pixel 10 and the third sub-pixel 30 in the odd-numbered column are regular quadrilaterals.

[0047] Among them, the first sub-pixel 10 and the third sub-pixel 30 of the odd-numbered column are themselves regular quadrilaterals.

[0048] It is understood that by setting the first sub-pixel 10 and the third sub-pixel 30 of the even-numbered columns with chamfered corners 40, the geometric centers of the light-emitting areas of the two first sub-pixels 10 and the two third sub-pixels 30 in adjacent rows and adjacent columns can form the irregular quadrilateral 3.

[0049] In one embodiment, in two first sub-pixels 10 and two third sub-pixels 30 in adjacent rows and adjacent columns, both first sub-pixels 10 are provided with a chamfer 40, and one third sub-pixel 30 is provided with a chamfer 40.

[0050] In one embodiment, among the two first sub-pixels 10 and the two third sub-pixels 30 in adjacent rows and adjacent columns, one first sub-pixel 10 is provided with a chamfer 40, and both third sub-pixels 30 are provided with a chamfer 40.

[0051] In one embodiment, in two first sub-pixels 10 and two third sub-pixels 30 in adjacent rows and adjacent columns, the two first sub-pixels 10 are provided with chamfered corners 40, and the two third sub-pixels 30 are provided with chamfered corners 40.

[0052] In one embodiment, the first sub-pixel 10 and the third sub-pixel 30, which are provided with the chamfer 40, are arranged in an irregular polygonal configuration.

[0053] It is understandable that the purpose of setting the chamfer 40 is to make the first sub-pixel 10 and the third sub-pixel 30 themselves form an irregular polygon, so that in two first sub-pixels 10 and two third sub-pixels 30 in adjacent rows and adjacent columns, the geometric center of the light-emitting area of ​​the first sub-pixel 10 and the geometric center of the light-emitting area of ​​the third sub-pixel 30 continuously form the irregular quadrilateral 3.

[0054] It should be noted that the geometric centers of the two first sub-pixels 10 and the two third sub-pixels 30 in adjacent rows and columns form the irregular quadrilateral 3, which can further reduce color mixing between adjacent sub-pixels of different colors compared to forming a regular quadrilateral.

[0055] In this embodiment, among the two first sub-pixels 10 and the two third sub-pixels 30 in adjacent rows and adjacent columns, at least one first sub-pixel 10 and at least one third sub-pixel 30 are arranged as irregular polygons, so that the geometric center of the light-emitting area of ​​the first sub-pixel 10 and the geometric center of the light-emitting area of ​​the third sub-pixel 30 continuously form the irregular quadrilateral 3. This avoids the existing pixel structure 1 that forms a regular quadrilateral and further reduces the color mixing of adjacent sub-pixels of different colors.

[0056] The pixel structure 1 described in any of the above embodiments of this application can not only reduce the number of sub-pixels by sharing sub-pixels, thereby achieving high PPI, but also alleviate the technical problem of severe color mixing between adjacent sub-pixels of different colors.

[0057] This application also proposes a display panel, a display module, and a display device, wherein the display panel, the display module, and the display device all include the pixel structure described in any of the above embodiments, which will not be repeated here.

[0058] The pixel structure provided in this application includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. The first sub-pixel and the third sub-pixel are arranged alternately in both row and column directions. In two first sub-pixels and two third sub-pixels in adjacent rows and columns, the line connecting the geometric center of the first sub-pixel and the geometric center of the third sub-pixel is arranged to form an irregular quadrilateral. A second sub-pixel is correspondingly disposed within one of the irregular quadrilaterals. In any irregular quadrilateral, at least one first sub-pixel and at least one third sub-pixel are provided with a chamfer. By providing a chamfer to at least one first sub-pixel and at least one third sub-pixel in two first sub-pixels and two third sub-pixels in adjacent rows and columns, the line connecting the geometric center of the first sub-pixel and the geometric center of the third sub-pixel is arranged to form an irregular quadrilateral. This achieves a new SPR arrangement pixel structure, alleviating the technical problem of color mixing easily occurring between adjacent sub-pixels of different colors in existing pixel structures.
