Pixel arrangement structure, display panel and mask assembly

Abstract

This application discloses a pixel arrangement structure, a display panel, and a mask assembly. The pixel arrangement structure includes multiple repeating units arranged in an array. Second and third sub-pixels, as well as the first sub-pixel, are adjacent, which reduces the spacing between the three sub-pixels in a first pixel unit used to form the same white light emission. Furthermore, the second and third sub-pixels can share a single first sub-pixel to form multiple first pixel units, thereby increasing the pixel density of the pixel arrangement structure and improving the display effect. At least one of the second and third sub-pixels includes a first edge and a second edge. The first edge is adjacent to the edge of the first sub-pixel, and the second edge includes an arc-shaped edge that protrudes and forms an arc along a direction away from the first sub-pixel. The arc-shaped edge increases the minimum distance between two adjacent second sub-pixels and two adjacent third sub-pixels, facilitating mask fabrication.

Description

Technical Field

[0001] This application relates to the field of display, specifically to a pixel arrangement structure, a display panel, and a mask assembly. Background Technology

[0002] Organic light-emitting diodes (OLEDs) are self-emissive display devices. Compared to traditional liquid crystal displays (LCDs), OLED technology does not require a backlight and is self-emissive. OLEDs use a thin layer of organic material and a glass substrate; when current flows through, the organic material emits light. Therefore, OLED display panels can significantly save energy, be made lighter and thinner, withstand a wider range of temperature variations than LCD panels, and have a wider viewing angle. OLED display panels are expected to become the next-generation flat panel display technology after LCDs and are currently one of the most watched technologies in the flat panel display field.

[0057] To better understand the present invention, various embodiments of the display panel, display device, and method for manufacturing the display panel will be described below with reference to the accompanying drawings.

[0058] This application provides a display panel, which may be an organic light-emitting diode (OLED) display panel.

[0059] Please see Figure 1 , Figure 1 This is a schematic diagram of the repeating unit in a pixel arrangement structure provided in the first aspect of this application.

[0060] The first aspect of this application provides a pixel arrangement structure, which includes a plurality of repeating units 100 arranged in an array along a first direction X and a second direction Y. Each repeating unit 100 includes a first sub-pixel 1101 and a second sub-pixel 120 and a third sub-pixel 130 surrounding the first sub-pixel 110. The second sub-pixel 120 and the third sub-pixel 130 are alternately distributed around the first sub-pixel 110.

[0061] At least one of the second sub-pixel 120 and the third sub-pixel 130 includes a first side 140 adjacent to the edge of the first sub-pixel 110 and a second side 150 connected to the first side 140. The second side 150 includes an arc-shaped side 151, which protrudes and is arc-shaped in a direction away from the first sub-pixel 110.

[0062] According to the pixel arrangement structure of the embodiments of this application, the pixel arrangement structure includes a plurality of repeating units 100 arranged in an array along a first direction X and a second direction Y. A first sub-pixel 110 and a second sub-pixel 120 are alternately distributed around the first sub-pixel 110. The second sub-pixel 120, the third sub-pixel 130, and the first sub-pixel 110 are all adjacent, which can reduce the spacing between the three sub-pixels in the first pixel unit 210 used to form the same white light emission. Furthermore, the second sub-pixel 120 and the third sub-pixel 130 can share a first sub-pixel 110 to form a plurality of first pixel units 210, which can improve the pixel density of the pixel arrangement structure and improve the display effect. At least one of the second sub-pixel 120 and the third sub-pixel 130 includes a first side 140 and a second side 150. The first side 140 is adjacent to the edge of the first sub-pixel 110. The second side 150 includes an arc-shaped edge 151, which protrudes and is arc-shaped in a direction away from the first sub-pixel 110. The arc-shaped edge 151 can increase the minimum distance between two adjacent second sub-pixels 120 and two adjacent third sub-pixels 130, which is convenient for mask fabrication.

[0063] Optionally, the ratio of the number of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 is 1:2:2. The number of the first sub-pixel 110 is relatively small, which reduces the number of the first sub-pixel 110 while ensuring pixel density, increases the pixel aperture ratio, increases the area of ​​the first sub-pixel 110, and thus increases the opening area on the mask corresponding to the first sub-pixel 110, which can simplify the structure of the mask.

[0064] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of a repeating unit in a pixel arrangement structure provided in another embodiment of the first aspect of this application.

[0065] In some alternative embodiments, at least one of the second sub-pixel 120 and the third sub-pixel 130 includes a first portion 160 and a second portion 170, the first portion 160 including an arcuate edge 151, the second portion 170 including a first edge 140 and two side edges 171 connecting the arcuate edge 151 and the first edge 140, the second portion 170 being located between the first portion 160 and the first sub-pixel 110.

[0066] In these optional embodiments, the first portion 140 of the second sub-pixel 120 of one of two adjacent repeating units 100 is adjacent to the first portion 140 of the third sub-pixel 130 of the other, with two adjacent arcuate edges 142, increasing the minimum distance between two adjacent second sub-pixels 120 and two adjacent third sub-pixels 130. The second portion 150 is located between the first portion 140 and the first sub-pixel 110, further increasing the minimum distance between two adjacent first sub-pixels 110, two adjacent second sub-pixels 120, and two adjacent third sub-pixels 130, facilitating mask fabrication. It also increases the distribution area of ​​the second sub-pixels 120 or the third sub-pixels 130, improving the display effect.

[0067] Optional, the two sides are parallel at 171.

[0068] Optionally, the first side 140 and the side 150 are perpendicular.

[0069] Optionally, the first sub-pixel 110 is a quadrilateral, and the second sub-pixel 120 and the third sub-pixel 130 are alternately distributed on the four sides of the first sub-pixel 110, and one side of the first sub-pixel 110 is adjacent to the second sub-pixel 120 or the third sub-pixel 130.

[0070] Optionally, the first sub-pixel 110 is a parallelogram or a rectangle.

[0071] Optionally, the first sub-pixel 110 can be either a rhombus or a square.

[0072] Optionally, the second sub-pixel 120 and the third sub-pixel 130 have the same shape.

[0073] Optionally, for adjacent second sub-pixel 120 and third sub-pixel 130, the arc edge 151 of the second sub-pixel 120 is tangent to the arc edge 151 of the third sub-pixel 130.

[0074] In these optional embodiments, the first side 140 is parallel to the second side 150, the two side edges 171 are parallel, and the first side 140 and the side edges 150 are perpendicular, making the second portion 160 rectangular. The first sub-pixel 110 is rhomboid or square, making the second sub-pixel 120 and the third sub-pixel 130 evenly distributed. The second sub-pixel 120 and the third sub-pixel 130 have the same shape and can share a mask. The above settings make the structure of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 more regular, which is convenient for mask fabrication. For adjacent second sub-pixels 120 and third sub-pixels 130, the arc edge 151 of the second sub-pixel 120 is tangent to the arc edge 151 of the third sub-pixel 130. On the one hand, the arc edge 151 increases the minimum distance between two adjacent second sub-pixels 120 and two adjacent third sub-pixels 130. On the other hand, the tangency of the two arc edges 151 can increase the pixel density.

[0075] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a repeating unit in a pixel arrangement structure provided in another embodiment of the first aspect of this application.

[0076] In some alternative embodiments, such as Figure 3 As shown, in the same repeating unit 100, a first sub-pixel 110, a second sub-pixel 120 and a third sub-pixel 130 form a first pixel unit 210, and the first sub-pixel 110 is shared by two adjacent first pixel units 210 in the same repeating unit 100.

[0077] In these optional embodiments, the first sub-pixel 110 is shared by two adjacent first pixel units 210, which can reduce the number of first sub-pixels 110 while ensuring pixel density, improve pixel aperture ratio, increase the area of ​​the first sub-pixel 110, and thus increase the aperture area on the mask corresponding to the first sub-pixel 110. This simplifies the structure of the mask and facilitates the use of sub-pixel rendering (SPR) technology.

[0078] The repeating unit 100 is a quadrilateral, and two first pixel units 210 can be formed in the repeating unit 100.

[0079] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of a repeating unit in a pixel arrangement structure provided in another embodiment of the first aspect of this application.

[0080] In some optional embodiments, in two adjacent repeating units 100 along the same direction (e.g., the first direction X or the second direction Y), the first sub-pixel 110 in the preceding repeating unit 100, the third sub-pixel 130 in the preceding repeating unit 100 adjacent to the following repeating unit 100, the first sub-pixel 110 in the following repeating unit 100, and the second sub-pixel 120 in the following repeating unit 100 adjacent to the third sub-pixel 130 in the preceding repeating unit 100 form a second pixel unit 220, and the first sub-pixel 110 is shared by four adjacent second pixel units 220 in the same direction.

[0081] In these alternative embodiments, the first sub-pixel 110 is shared by four adjacent second pixel units 220, which can reduce the number of first sub-pixels 110 while ensuring pixel density, improve pixel aperture ratio, increase the area of ​​the first sub-pixel 110, and thus increase the aperture area on the mask corresponding to the first sub-pixel 110, which can simplify the structure of the mask and facilitate the use of SPR technology.

[0082] The aforementioned pixel arrangement structure facilitates the use of SPR (Surface Reduction) technology, which uses fewer first sub-pixels 110 to achieve the same display resolution. For example, where 2 pixels originally required 6 first sub-pixels 110, SPR technology requires only 4. Therefore, for display panels with the same resolution, the number of first sub-pixels 110 is only 2 / 3 of the original after using SPR technology. This allows for an increase in the size of the first sub-pixels 110, ensuring a high yield rate for the deposition of the first sub-pixels 110 while still achieving the same display resolution.

[0083] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of a repeating unit in a pixel arrangement structure provided in another embodiment of the first aspect of this application.

[0084] In some alternative embodiments, in the same repeating unit 100, at least one of the first sub-pixel 110, the second sub-pixel 120 and the third sub-pixel 130 is symmetrically arranged about the center line connecting the two opposite sides of the first sub-pixel 110.

[0085] In these optional embodiments, at least one of the first sub-pixel 110, the second sub-pixel 120, and the third sub-pixel 130 is symmetrically arranged about the center line connecting two opposite sides of the first sub-pixel 110. This makes the distribution of different colored sub-pixels in the pixel arrangement structure more uniform.

[0086] Optionally, in the repeating unit 100, the two second sub-pixels 120 are symmetrically distributed about the center line connecting the two pairs of sides of the first sub-pixel 110, and / or, the two third sub-pixels 130 are symmetrically distributed about the center line connecting the other two pairs of sides of the first sub-pixel 110.

[0087] In these optional embodiments, when the repeating units 100 are arranged in an array along the first direction X and the second direction Y, since the two second sub-pixels 120 and / or the two third sub-pixels 130 are symmetrically distributed about the diagonal, by reasonably arranging the repeating units 100, the second sub-pixel 120 of one of the two adjacent repeating units 100 and the third sub-pixel 130 of the other can be adjacent to each other, thereby enabling the deposition of multiple second sub-pixels 120 and / or third sub-pixels 130 using a larger mask opening.

[0088] The two second sub-pixels 120 and / or the two third sub-pixels 130 are symmetrically distributed about the center line connecting the two opposite sides of the first sub-pixel 110. This makes the angle between the center line connecting the two second sub-pixels 120 or the two third sub-pixels 130 and the first direction X within the repeating unit 100 45 degrees, which helps to reduce the jagged edges of the repeating unit 100 and improve the display effect.

[0089] Optionally, the second sub-pixel 120 and the third sub-pixel 130 have the same shape and equal area.

[0090] In these alternative embodiments, the second sub-pixel 120 and the third sub-pixel 130 are identical, making the repeating unit 100 structure more regular and further improving the display effect of the pixel arrangement structure. In addition, the second sub-pixel 120 and the third sub-pixel 130 can be vapor-deposited using the same mask, simplifying the vapor deposition process of the pixel arrangement structure.

[0091] Optionally, the line connecting the centers of two second sub-pixels 120 in the same repeating unit 100 forms an angle of 40°-50° with the first direction X.

[0092] Optionally, the line connecting the centers of two second sub-pixels 120 in the same repeating unit 100 forms an angle of 45° with the first direction X.

[0093] Optionally, the line connecting the centers of two third sub-pixels 130 in the same repeating unit 100 has an angle of 40°-50° with the first direction X.

[0094] Optionally, the line connecting the centers of two third sub-pixels 130 in the same repeating unit 100 forms an angle of 45° with the first direction X.

[0095] In these alternative embodiments, after the mask has completed the deposition of the second sub-pixel 120, it can be rotated 45 degrees to continue deposition of the third sub-pixel 130.

[0096] In some alternative embodiments, the square 230 formed by the center line connecting the first sub-pixels 110 of the four adjacent repeating units 100 includes two second sub-pixels 120 and two third sub-pixels 130.

[0097] Optionally, within the square 230 formed by the center line connecting the first sub-pixels 110 of the four adjacent repeating units 100, the second sub-pixel 120 and the third sub-pixel 130 are tangent, the two second sub-pixels 120 are set at two opposite corners of the square 230, and the two third sub-pixels 130 are set at the other two opposite corners of the square 230.

[0098] In these alternative embodiments, the two second sub-pixels 120 and the two third sub-pixels 130 inside the square 230 are arranged diagonally, increasing the minimum distance between two adjacent first sub-pixels 110, two adjacent second sub-pixels 120 and two adjacent third sub-pixels 130, which facilitates the fabrication of the mask.

[0099] In some alternative embodiments, the repeating units 100 are arranged in an array along a first direction X and a second direction Y; two adjacent columns of repeating units 100 along the first direction X are symmetrically distributed about an axis extending along the second direction Y.

[0100] The repeating units 100 are arranged in an array along a first direction X and a second direction Y. Two adjacent columns of repeating units 100 along the first direction X are symmetrically distributed about an axis extending along the second direction Y. This allows the second sub-pixel 120 of one of the repeating units 100 in two adjacent columns to be adjacent to the third sub-pixel 130 of the other, and the second sub-pixel 120 or the third sub-pixel 130 of the repeating units 100 in two adjacent columns to share the same opening for vapor deposition.

[0101] Optionally, two adjacent rows of repeating units 100 along the second direction Y are symmetrically distributed about an axis extending along the first direction X.
