Description

Technical Field

[0001] The present invention relates to the field of display technologies, and in particular, to a pixel arrangement structure, an organic light-emitting display panel, a high-precision metal mask plate, and a display device. Background Art

[0002] Organic Light Emitting Diode (OLED) display devices are one of the hotspots in the research field of flat panel displays today. Compared with liquid crystal displays, OLED display devices have the advantages of low power consumption, low production cost, self-luminescence, wide viewing angle, and fast response speed. Currently, in the field of flat panel displays such as mobile phones, PDAs, and digital cameras, OLED display devices have begun to replace traditional liquid crystal displays (LCDs).

[0003] The structure of an OLED display device mainly includes: a substrate, and pixels arranged in a matrix on the substrate. Among them, each pixel generally forms an organic light-emitting structure at a corresponding pixel position on the array substrate through an organic material by using an evaporation coating technology through a high-precision metal mask plate.

[0004] However, currently in OLED display devices, the distance between pixels in the pixel arrangement structure is relatively large, resulting in a small pixel aperture area under the condition of the same resolution. Therefore, it is necessary to increase the driving current to meet the brightness requirements of the display. However, when an OLED operates under a large driving current, the aging speed of the device is likely to increase, thereby shortening the lifespan of the OLED display device.

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] The shapes and sizes of the components in the drawings do not reflect the true proportions, and the purpose is only to schematically illustrate the content of the present invention.

[0038] A pixel arrangement structure provided by an embodiment of the present invention, as Figure 1 shown, includes: a first sub-pixel 01, a second sub-pixel 02, and a third sub-pixel 03;

[0039] The first sub-pixel 01 is located at the center position and the four vertex positions of the first virtual quadrilateral;

[0040] The second sub-pixel 02 is located at the midpoint position of the side of the first virtual quadrilateral;

[0041] The third sub-pixel 03 is located within a second virtual quadrilateral. The second virtual quadrilateral is formed by sequentially connecting two second sub-pixels 02 located at the midpoint positions of two adjacent sides of the first virtual quadrilateral, and the first sub-pixels 01 that are adjacent to both of the two second sub-pixels 02 and are located at the center position and a vertex position of the first virtual quadrilateral as vertices. And four second virtual quadrilaterals form a first virtual quadrilateral;

[0042] Within the first virtual quadrilateral, the minimum distance between the first sub-pixel 01 located at the center position of the first virtual quadrilateral and the two third sub-pixels 03 within the second virtual quadrilateral at the diagonal is equal and is the first distance L1; the minimum distance between the first sub-pixel 01 located at the center position of the first virtual quadrilateral and the two third sub-pixels 03 within the second virtual quadrilateral at the other diagonal is equal and is the second distance L2, and the first distance L1 is less than the second distance L2.

[0043] Specifically, compared with the existing pixel arrangement structure, the pixel arrangement method provided by the embodiments of the present invention can closely arrange the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03 under the same process conditions, and minimize the distance between adjacent pixels as much as possible. Moreover, by adjusting the minimum distance between the first sub-pixel 01 at the center position and the third sub-pixels 03 at the two diagonal positions within the first virtual quadrilateral so that the distances on the two diagonals are not equal, the distance between the third sub-pixel 03 and the adjacent first sub-pixel 01 can be further reduced. Thereby, the pixel aperture area is increased under the condition of the same resolution, the driving current of the display device is reduced, and further the service life of the display device is increased.

[0044] It should be noted that in the pixel arrangement structure provided by the embodiments of the present invention, when it is mentioned that a pixel is at a certain position, it refers to the position range where the pixel is located, as long as it is ensured that the pixel overlaps with this position. In specific implementation, the center of the pixel can overlap with this position. Of course, the center of the pixel can also not overlap with this position, that is, there is an offset between the two, which is not limited herein. And the center of the pixel can be the geometric center of the pixel pattern or the center of the pixel emission color, which is not limited herein.

[0045] Optionally, in the pixel arrangement structure provided by the embodiments of the present invention, in order to ensure that each pixel can be evenly distributed, the centers of each pixel are preferably close to the corresponding positions as much as possible.

[0046] It should be noted that the first virtual quadrilateral mentioned in the display arrangement structure provided by the embodiments of the present invention is Figure 1 the largest dashed box in Figure 1 and the second virtual quadrilateral is Figure 1 the small dashed box in

[0047] It should be noted that the minimum distance between each sub-pixel mentioned in the display arrangement structure provided by the embodiments of the present invention refers to the shortest distance between the adjacent edges of each sub-pixel.

[0048] Optionally, in the pixel arrangement structure provided by the embodiments of the present invention, the minimum distance between the third sub-pixel 03 and the adjacent first sub-pixel 01 needs to be greater than or equal to the process limit distance to meet the process requirements. And generally, the minimum distance is the process limit distance. The numerical range of the minimum distance is generally related to the manufacturing process used. When forming the pixel pattern by using a high-precision metal mask (FMM) in combination with an etching process, the minimum distance is about 16 μm. When forming the pixel pattern by using processes such as laser or electroforming, the minimum distance will be smaller.

[0049] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figure 2 shown, within the first virtual quadrilateral, the minimum distance between the first sub-pixel 01 located at the central position of the first virtual quadrilateral and each second sub-pixel 02 is equal and is the third distance L3.

[0050] Specifically, by adjusting the minimum distance between the first sub-pixel 01 located at the central position of the first virtual quadrilateral and each second sub-pixel 02 to be equal, the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03 can be closely arranged under the same process conditions, minimizing the distance between adjacent pixels as much as possible, thereby increasing the pixel aperture area under the condition of the same resolution, reducing the driving current of the display device, and further increasing the lifespan of the display device.

[0051] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, by adjusting the distances, shapes, and areas between the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03, as Figure 2 shown, the second distance L2 can be greater than the third distance L3, and the third distance L3 can be greater than the first distance L1.

[0052] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figure 3 shown, the minimum distance between the second sub-pixel 02 and the adjacent four third sub-pixels 03 is equal and is equal to the first distance L1.

[0053] Specifically, by adjusting the minimum distance between the third sub-pixel 03 and each second sub-pixel 02 to be equal, the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03 can be closely arranged under the same process conditions, minimizing the distance between adjacent pixels as much as possible, thereby increasing the pixel aperture area under the condition of the same resolution, reducing the driving current of the display device, and further increasing the lifespan of the display device.

[0054] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figure 4 shown, within the first virtual quadrilateral, the minimum distance between two third sub-pixels 03 located in the second virtual quadrilateral adjacent in row is the fourth distance L4, and the minimum distance between two third sub-pixels 03 located in the second virtual quadrilateral adjacent in column is the fifth distance L5, and the fifth distance L5 is greater than the fourth distance L4. Specifically, it can be considered that the adjacent four third sub-pixels 03 form a parallelogram, which can minimize the distance between adjacent third sub-pixels 03 to the greatest extent, thereby increasing the pixel aperture area under the condition of the same resolution, reducing the driving current of the display device, and further increasing the lifespan of the display device.

[0055] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figure 5 shown, the distance between the first sub-pixel 01 located at the center position of the first virtual quadrilateral and each first sub-pixel 01 located at the four vertex positions of the first virtual quadrilateral is equal and is the sixth distance L6, and the sixth distance L6 is greater than the fifth distance L5. Specifically, it can be considered that four adjacent first sub-pixels 01 form an equilateral quadrilateral, so as to minimize the distance between adjacent first sub-pixels 01, thereby increasing the pixel aperture area under the condition of the same resolution, reducing the driving current of the display device, and further increasing the service life of the display device.

[0056] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figure 6 shown, within the first virtual quadrilateral, the minimum distance between adjacent second sub-pixels 02 is equal and is the seventh distance L7, and the seventh distance L7 is greater than the fifth distance L5 and less than the sixth distance L6. Specifically, it can be considered that four adjacent second sub-pixels 02 form an equilateral quadrilateral, so as to minimize the distance between adjacent second sub-pixels 02, thereby increasing the pixel aperture area under the condition of the same resolution, reducing the driving current of the display device, and further increasing the service life of the display device.

[0057] Optionally, the specific shapes, positional relationships, parallel and angular relationships, etc. of the second sub-pixel 02, the first sub-pixel 01, and the third sub-pixel 03 can be designed as needed. In actual processes, due to process conditions or other factors, there may also be some deviations. Therefore, as long as the shapes, positions, and relative positional relationships of the sub-pixels generally meet the above conditions, they all belong to the pixel arrangement structure provided by the embodiments of the present invention.

[0058] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, the shape of the third sub-pixel 03 can be a regular shape, such as regular shapes in the traditional sense such as triangles, quadrilaterals, pentagons, hexagons, octagons, rhombuses, circles, ellipses, etc. Or, the shape of the third sub-pixel 03 can also be an irregular shape, which is not limited herein. And, a certain side of the irregular shape can be a curve, that is, the shape of the third sub-pixel 03 can be a figure including a curve, for example, it can be a figure composed of part of a curve and part of a straight line, which is not limited herein. Figures 1 to 7 In all of them, the third sub-pixel 03 is taken as an octagon as an example for illustration.

[0059] In order to ensure that during preparation, for the same kind of pixel, the mask pattern can be consistent, so as to simplify the lithography process. Optionally, in the pixel arrangement structure provided by the embodiments of the present invention, as Figures 1 to 7 shown, the shapes of the third sub-pixels 03 can be the same.

[0060] Alternatively, optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, the shapes of at least two third sub-pixels 03 may also be inconsistent, which is not limited herein.

[0061] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, two third sub-pixels 03 located in the direction of one diagonal of the first virtual quadrilateral have the same shape, two third sub-pixels 03 located in the direction of the other diagonal of the first virtual quadrilateral have the same shape, and the shapes of the third sub-pixels located in different diagonal directions of the first virtual quadrilateral are different. Alternatively, the shapes of the four third sub-pixels 03 within the first virtual quadrilateral may also be different from each other, which is not limited herein.

[0062] Moreover, optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, in a first virtual quadrilateral, when the four third sub-pixels 03 have the same or similar shapes, their arrangement angles may be the same, or as Figures 1 to 7 shown, within the first virtual quadrilateral, the four third sub-pixels 03 are distributed in an "X" shape, that is, the four third sub-pixels 03 are strip-shaped and all point to the center position of the first virtual quadrilateral along the length direction of the strip; or, the angles of the four third sub-pixels 03 may also be rotated arbitrarily, which is not limited herein.

[0063] To ensure that during preparation, for the same type of pixel, the mask pattern can be consistent, thereby simplifying the lithography process, optionally, in the pixel arrangement structure provided by the embodiments of the present invention, as Figures 1 to 7 shown, the shapes of the first sub-pixels 01 can be the same, for example, they can be equilateral quadrilaterals.

[0064] Of course, in specific implementation, in the above pixel arrangement structure provided by the embodiments of the present invention, the shapes of at least two first sub-pixels 01 may also be inconsistent, which is not limited herein.

[0065] Moreover, optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, in a first virtual quadrilateral, when the five first sub-pixels 01 have the same or similar shapes, their arrangement angles may be the same, or their arrangement angles may be rotated arbitrarily, which is not limited herein.

[0066] To ensure that during preparation, for the same type of pixel, the mask pattern can be consistent, thereby simplifying the lithography process, optionally, in the pixel arrangement structure provided by the embodiments of the present invention, as Figures 1 to 7 shown, the shapes of the second sub-pixels 02 are the same, for example, they can be rectangles.

[0067] Of course, in specific implementation, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figure 6As shown, the shapes of at least two second sub-pixels 02 may also be inconsistent, which is not limited herein.

[0068] Moreover, optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, when the four second sub-pixels 02 have the same or similar shapes in a first virtual quadrilateral, their arrangement angles may be the same, or their arrangement angles may be rotated arbitrarily, which is not limited herein.

[0069] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figures 1 to 7 shown, within the first virtual quadrilateral, the second sub-pixels 02 may be distributed in a windmill shape. That is, the four second sub-pixels 02 are strip-shaped, and two adjacent second sub-pixels 02 are rotated 90 degrees in the same direction (such as the clockwise direction) along the length direction of the strip.

[0070] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, the shape of the first sub-pixel 01 and the second sub-pixel 02 may be the same, for example, both are quadrilateral, or the shape of the first sub-pixel 01 and the second sub-pixel 02 may also be inconsistent, which is not limited herein.

[0071] In specific implementation, in the above pixel arrangement structure provided by the embodiments of the present invention, the shapes of the first sub-pixel 01 and the second sub-pixel 02 may be regular shapes or irregular shapes, which is not limited herein. Generally, regular graphics are easier to manufacture. Therefore, optionally, in the pixel arrangement structure provided by the embodiments of the present invention, the shapes of the first sub-pixel 01 and the second sub-pixel 02 are both regular graphics, such as circles, ellipses, regular polygons such as squares, regular hexagons, regular octagons, and other convex polygons, or curved polygons, etc., which is not limited herein.

[0072] It should be noted that the inconsistent graphics of the pixels mentioned in the embodiments of the present invention refer to the inconsistent shapes of the pixels. For example, one is circular and the other is rectangular. On the contrary, the consistent graphics of the pixels mentioned in the embodiments of the present invention refer to the similar or same shapes of the pixels. For example, the shapes of two pixels are both triangular. Regardless of whether the areas are equal, it is considered that the shapes of the two pixels are consistent.

[0073] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, the first sub-pixel 01 may be a red sub-pixel, the second sub-pixel 02 may be a blue sub-pixel; the third sub-pixel 03 is a green sub-pixel. Thus, as Figure 7 shown, the green sub-pixel G located within the second virtual quadrilateral may form a light-emitting pixel point with the red sub-pixel R and the blue sub-pixel B located at any two adjacent corners of the second virtual quadrilateral.

[0074] Further, since the human eye is more sensitive to green light, optionally, in the pixel arrangement structure provided by the embodiments of the present invention, as Figures 1 to 6 shown, the area of the third sub-pixel 03 can be smaller than the area of the second sub-pixel 01, that is, the area of the green sub-pixel is smaller than the area of the blue sub-pixel. Generally, the area of the green sub-pixel is also smaller than the area of the red sub-pixel. In other words, the area of the green sub-pixel is the smallest. Since the luminous efficiency and lifespan of the blue sub-pixel are both lower than those of the red sub-pixel, optionally, the area of the first sub-pixel 01 can be smaller than the area of the second sub-pixel 02, that is, the area of the blue sub-pixel is set to be larger than the area of the red sub-pixel.

[0075] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figures 1 to 7 shown, the areas of the third sub-pixels 03 can be the same. Thus, it is ensured that in any light-emitting pixel point composed of the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03, the luminous areas of the third sub-pixels 03 are the same.

[0076] Of course, in specific implementation, in the above pixel arrangement structure provided by the embodiments of the present invention, there can also be at least two third sub-pixels 03 with different areas, which is not limited herein.

[0077] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figures 1 to 7 shown, the areas of the first sub-pixels 01 can be the same. Thus, it is ensured that in any light-emitting pixel point composed of the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03, the luminous areas of the first sub-pixels 01 are the same.

[0078] Of course, in specific implementation, in the above pixel arrangement structure provided by the embodiments of the present invention, there can also be at least two first sub-pixels 01 with different areas, which is not limited herein.

[0079] Optionally, in the above pixel arrangement structure provided by the embodiments of the present invention, as Figures 1 to 7 shown, the areas of the second sub-pixels 02 can be the same. Thus, it is ensured that in any light-emitting pixel point composed of the first sub-pixel 01, the second sub-pixel 02, and the third sub-pixel 03, the luminous areas of the second sub-pixels 02 are the same.

[0080] Of course, in specific implementation, in the above pixel arrangement structure provided by the embodiments of the present invention, there can also be at least two second sub-pixels 02 with different areas, which is not limited herein.

That is, two adjacent pixel arrangement structures share the first sub-pixel 01 and the second sub-pixel 02 located on the side edges of adjacent first virtual quadrilaterals. For example Figure 8 In each of the three pixels circled by an ellipse in the figure are the pixels shared by two adjacent pixel arrangement structures. Since the principle of solving problems of this organic electroluminescent display panel is similar to that of the aforementioned pixel arrangement structure, the implementation of this organic electroluminescent display panel can refer to the implementation of the aforementioned pixel arrangement structure, and the repeated parts will not be elaborated

The third sub-pixel 01 is located within the second virtual quadrilateral surrounded by two first sub-pixels 01 and two second sub-pixels 02. In this way, when displaying, any two adjacent first sub-pixels 01 and second sub-pixels 02 can form a light-emitting pixel point with a third sub-pixel 03 adjacent to them, and the pixels achieve a high-resolution display effect from a low-resolution physical resolution through the color borrowing principle

[0083] Based on the same inventive concept, the embodiments of the present invention also provide a high-precision metal mask for manufacturing the above-mentioned pixel arrangement structure provided by the embodiments of the present invention, including: a plurality of uniformly arranged opening regions, and the opening regions correspond to the shapes and positions of the first sub-pixel, the second sub-pixel or the third sub-pixel

This display device can be: a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, or any product or component with a display function. The implementation of this display device can refer to the embodiments of the above-mentioned display panel, and the repeated parts will not be elaborated
