Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display panel and display device. Background Technology

[0002] Glasses-free 3D display technology allows users to experience stereoscopic vision without the aid of auxiliary tools. Its principle is binocular parallax imaging, where the viewer's left and right eyes receive slightly different images. These images are then analyzed and integrated by the brain to create a unified scene, allowing the viewer to perceive the depth of objects and thus creating a sense of depth. 3D display technology enhances both the display effect and the viewer's comfort.

[0003] In related technologies, organic light-emitting diodes (OLEDs) fabricated based on the color filter thin film method (WOLED+CF) have subdivided subpixels in the row direction (X direction) and, through specific structural design, have achieved continuous visual space in 3D displays and eliminated moiré patterns.

[0004] However, for organic light-emitting diodes (OLEDs) fabricated using the fine metal mask (FMM) process, which has higher luminous efficiency, due to the limitations of the manufacturing process, even with the same optical design and pixel structure, holes may appear at certain viewing angles, resulting in moiré patterns and affecting the display effect.

[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0036] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0037] Color filter thin film (WOLED+CF) and fine metal mask (FMM) evaporation processes are common methods for fabricating organic light-emitting diodes (OLEDs). The color filter thin film (WOLED+CF) method is generally based on the fabrication of a white OLED combined with a color filter (CF). First, a white OLED device is fabricated, then the three primary colors are obtained through the color filter (CF), and finally, the three primary colors are combined to achieve color display.

[0038] In the color filter thin film method (WOLED+CF) fabrication process, the pixel structure arrangement is as follows: Figure 1As shown, the pixel arrangement structure consists of pixel islands 100' arranged in columns and a lens array layer 11, wherein the lens array layer 11 consists of microlenses 10 arranged in columns. Pixel island 100'a is the first column of pixel islands along the X direction, pixel island 100'b is the second column of pixel islands along the X direction, and so on; microlens 10a is the first column of cylindrical lenses along the X direction, microlens 10b is the second column of microlenses along the X direction, and so on. Each pixel island 100' is subdivided into multiple sub-pixels 1 in the row direction (X direction), each sub-pixel 1 having the same width W and equal spacing G, and the spacing G is equal to the width W of the light-emitting area of ​​the sub-pixel. The width of a pixel island 100' is equal to the width of the two microlenses 10 of the lens array layer 11. Furthermore, the relative relationships between each sub-pixel 1 and the microlens 10 within the same pixel island 100' are designed not to form repeating units. That is, the gaps G between adjacent sub-pixels 1 of sub-pixel islands 130R, 130G, and 130B in the multiple sub-pixel islands 130 can be complementary to the corresponding sub-pixels 1 in the remaining sub-pixel groups 150. Specifically, sub-pixels P2, P4, P6, P8, and P10 sequentially fill the gaps between sub-pixels P1 and P3, P3 and P5, P5 and P7, P7 and P9, and P9 and P11, respectively. The final optical path diagram is as follows: Figure 2a , Figure 2b As shown, where, Figure 2b yes Figure 2a The enlarged view shows that, with this pixel arrangement, the light-emitting areas of the sub-pixels interweave and complement each other relative to the two cylindrical lens units, making the light emission direction of the sub-pixels continuous in the 3D display visual space and eliminating moiré patterns.

[0039] Compared to organic light-emitting diodes (OLEDs) fabricated using the color filter thin film method (WOLED+CF), organic light-emitting diodes (OLEDs) fabricated using the fine metal mask (FMM) evaporation process have higher luminous efficiency.

[0040] However, the fabrication of organic light-emitting diodes (OLEDs) using fine metal masks (FMMs) has certain requirements. If the same optical design and pixel structure are used as in the color filter film method (WOLED+CF), the pixel arrangement will be as follows: Figure 3As shown, the width of a pixel island 100' is equal to the width of the two microlenses 10 of the lens array layer 11. The sub-pixels 1 of sub-pixel islands 130R, 130G, and 130B in the multiple sub-pixel islands 130 cannot achieve complementary light emission space within the corresponding area of ​​the lens array layer 11. Although sub-pixels P2, P4, and P6 sequentially fill the gaps between sub-pixels P1 and P3, P3 and P5, and P5 and P7 respectively, the gaps between sub-pixels P7 and P9, and between P9 and P11, are not filled. Correspondingly, the optical path is as follows: Figure 4a , Figure 4b As shown, where, Figure 4b yes Figure 4a A magnified view of a portion of the image. Holes appear in the optical path at certain viewing angles, leading to moiré patterns and preventing the achievement of the same continuous visual space effect in naked-eye 3D displays as organic light-emitting diodes (OLEDs) fabricated using the color filter film method (WOLED+CF).

[0041] To address the aforementioned problems, embodiments of this application provide a display panel, such as... Figure 5 , Figure 6 and Figure 7 The display panel includes a pixel array layer 13 and a lens array layer 11 stacked together. The pixel array layer 13 and the lens array layer 11 are stacked in the third direction Z (film deposition direction) and located at different depths. The lens array layer 11 includes a plurality of microlenses 10 arranged along the first direction X (row direction).

[0042] The pixel array layer 13 includes a plurality of pixel islands 100 arranged in an array. Each pixel island 100 includes a plurality of sub-pixel islands 130 arranged along a second direction Y (column direction), and each sub-pixel island includes a plurality of sub-pixels 1. Sub-pixels 1 within the same sub-pixel island 130 emit the same color. Each sub-pixel island 130 is divided into a plurality of sub-pixel groups 150 arranged along a first direction X. Each sub-pixel within the sub-pixel island 130 is assigned to a corresponding sub-pixel group 150. The orthographic projection of each sub-pixel group 150 onto the lens array layer 11 falls within the same microlens 10.

[0043] Within the same sub-pixel island 130, the gaps G between adjacent sub-pixels 1 in a sub-pixel group 150 can be complementary to the corresponding sub-pixels 1 in the other sub-pixel groups 150.

[0044] Due to process limitations, each sub-pixel group 150 cannot emit light continuously. In this embodiment, sub-pixels 1 from other sub-pixel groups 150 within the same sub-pixel island 130 are used to fill the light-emitting gaps within that sub-pixel group 150, thus making the discontinuously emitting sub-pixel group 150 equivalent to a continuously emitting pixel structure. Therefore, the pixel array layer 13 described above can achieve a continuous 3D display effect through multiple microlenses 10 within the lens array layer 11.

[0045] Figure 5 Two adjacent pixel islands 100 located in the same row are schematically shown: pixel island 100a and pixel island 100b. Each pixel island 100 has the same structure; the structure of pixel island 100a is described below as an example. Pixel island 100a includes three sub-pixel islands 130: a first sub-pixel island 130R, a second sub-pixel island 130G, and a third sub-pixel island 130B. The first sub-pixel island 130R, the second sub-pixel island 130G, and the third sub-pixel island 130B are arranged sequentially along the column direction Y. The first sub-pixel island 130R emits red light, the second sub-pixel island 130G emits green light, and the third sub-pixel island 130B emits blue light. Correspondingly, the light-emitting materials of the sub-pixels 1 contained in the first sub-pixel island 130R, the second sub-pixel island 130G, and the third sub-pixel island 130B are different. The first sub-pixel island 130R has sub-pixel 1a with organic light-emitting material for emitting red light, the second sub-pixel island 130G has sub-pixel 1b with organic light-emitting material for emitting green light, and the third sub-pixel island 130B has sub-pixel 1c with organic light-emitting material for emitting blue light. Therefore, when depositing organic light-emitting materials using a fine metal mask (FMM) evaporation process, it is necessary to fabricate the material in three stages, depositing one type of organic light-emitting material of different colors each time.

[0046] For any two adjacent pixel islands 100 located in the same row, sub-pixel islands 130 emitting the same color light are located at the same height in the column direction Y. Figure 5 For example, the first sub-pixel island 130R in pixel island 100a that emits red light and the first sub-pixel island 130R in pixel island 100b that emits red light are at the same height in the column direction; the second sub-pixel island 130G in pixel island 100a that emits green light and the second sub-pixel island 130G in pixel island b that emits green light are at the same height in the column direction; the third sub-pixel island 130B in pixel island 100a that emits blue light and the third sub-pixel island 130B in pixel island 100b that emits blue light are at the same height in the column direction.

[0047] The first sub-pixel island 130R, the second sub-pixel island 130G, and the third sub-pixel island 130B are identical except for their emission colors. The structure of any one of the sub-pixel islands 130 is explained below as an example.

[0048] Each subpixel island 130 includes three subpixel groups 150 arranged along the row direction X: a first subpixel group 150a, a second subpixel group 150b, and a third subpixel group 150c. The second subpixel group 150b is located between the first subpixel group 150a and the third subpixel group 150c. The number of subpixels 1 contained in each subpixel group 150a, 150b, and 150c may be unequal. Furthermore, some subpixel groups 150 may not even contain any subpixels 1. Figure 5 In the first subpixel group 150a, there are 7 subpixels 1 and 6 gaps (each gap is located between two adjacent subpixels); the second subpixel group 150b has 6 subpixels 1 and 7 gaps; the third subpixel group 150c has no subpixels 1.

[0049] It should be noted that the term "gap" used in this text does not mean that the space between two sub-pixels is not filled with any solid or liquid; it simply indicates that the two sub-pixels are not connected together, and the "gap" refers only to the space between them. In reality, the "gap" between sub-pixels is usually filled with opaque materials such as pixel-defining layers or black matrices.

[0050] The positions and widths W of the six sub-pixels 1 in the second sub-pixel group 150b correspond to the positions and widths G of the six gaps in the first sub-pixel group 150a, respectively. The sum of the widths W of the six sub-pixels 1 in the second sub-pixel group 150b is equal to the sum of the widths G of the six gaps in the first sub-pixel group 150a. This ensures that, after passing through the microlens 10, the light emitted by the six sub-pixels 1 in the second sub-pixel group 150b can well fill the area corresponding to the six gaps in the first sub-pixel group 150a, achieving continuity in the 3D display of this area.

[0051] Similarly, the positions and widths W of the seven sub-pixels 1 within the first sub-pixel group 150a correspond to the positions and widths G of the seven gaps within the second sub-pixel group 150b, respectively. The sum of the widths W of the seven sub-pixels 1 within the first sub-pixel group 150a is equal to the sum of the widths G of the seven gaps within the second sub-pixel group 150b. The seven sub-pixels 1 within the first sub-pixel group 150a can effectively correspond to and complement the seven gaps within the second sub-pixel group 150b.

[0052] Similarly, the seven sub-pixels 1 in the first sub-pixel group 150a and the six sub-pixels 1 in the second sub-pixel group 150b correspond well to the entire area of ​​the complementary third sub-pixel group 150c.

[0053] As described above, when subpixel 1 is formed by evaporation using a fine metal mask (FMM), a large spacing needs to be set between subpixels 1 emitting the same color in adjacent pixel islands. The position and space corresponding to this large spacing are usually filled with opaque materials (such as pixel limiting layer materials or black matrix materials). Therefore, in this paper, the position and area corresponding to this large spacing designed for the FMM process will also be referred to as the "opaque area". Figure 5 In the process, no sub-pixels 1 are set in the third sub-pixel group 150c, and therefore it can be regarded as a whole as the opaque area or a part of the opaque area. The width of the opaque area is much larger than the width G of the gap between adjacent sub-pixels 1 in the same sub-pixel island 130. The width of the opaque area is usually greater than or equal to 38 μm (micrometers) to obtain better process results.

[0054] Within the display panel, all sub-pixels 1 can have the same shape, size, etc. Within the same sub-pixel island 130, the width G of the gap between adjacent sub-pixels 1 can also be equal, and the width G of the gap can be equal to the width W of each sub-pixel 1. The width G of the gap between adjacent sub-pixels 1 is typically greater than or equal to 4 μm.

[0055] The function of each microlens 10 in the lens array layer 11 is to reduce the light emission angle of each sub-pixel 1, so that the light emission directions of each sub-pixel 1 do not overlap or interfere in space. Each microlens 10 can be a cylindrical lens, and the column direction Y is the length direction of the cylindrical lens. In the column direction, each microlens 10 can cover multiple pixel islands 100, or even cover an entire column of pixel islands 100.

[0056] The fabrication process of the lens array layer 11 may include: using polyethylene terephthalate (PET), polymethyl methacrylate (PMMA) or resin material as a substrate, and obtaining the desired lens array layer 11 structure on the substrate by means of ultraviolet curing, imprinting or other methods.

[0057] Taking a resin material as an example, the lens array layer 11 can be made of a high refractive index resin and a low refractive index resin, wherein the high refractive index resin is located on the side closer to the pixel array layer 13, and the low refractive index resin is located on the side farther away from the pixel array layer 13.

[0058] The display panel may further include a spacer layer 12, which is located between the pixel array layer 13 and the lens array layer 11 to achieve the placement height of the lens array layer 11. The spacer layer 12 is preferably a thin resin glass.

[0059] Figure 7The image shows a more detailed arrangement of pixel islands 100. Each row contains three pixel islands 100: a first pixel island 100a, a second pixel island 100b, and a third pixel island 100c. The structure of each pixel island 100 and the positional relationships between adjacent pixel islands 100 are shown in the image. Figure 5 Same as above.

[0060] Figure 8a and Figure 8b yes Figure 5 , Figure 7 The optical path diagram of the display panel, in which Figure 8b yes Figure 8a A magnified view of a portion of the image. For example... Figure 8a and Figure 8b and combined Figure 5 , Figure 7 The six sub-pixels 1 in the second sub-pixel group 150b (sub-pixels P2, P4, P6, P8, P10, and P12) sequentially fill the six gaps in the first sub-pixel group 150a (the gap between sub-pixels P1 and P3, P3 and P5, P5 and P7, P7 and P9, P9 and P11, and P11 and P13). The final result is as follows: Figure 8a and Figure 8b The equivalent continuous light emission effect is shown. This pixel island structure design can increase the light coverage area of ​​the edge portion of the pixel island 100, thereby achieving continuous light emission, effectively eliminating moiré patterns, and ensuring display quality.

[0061] In the above embodiment, the width M of the gap between the different colored sub-pixel islands 130 located in different rows is equal and is greater than the width G of the gap between adjacent sub-pixels 1.

[0062] When applying the above pixel island array arrangement to a 27-inch display panel with a resolution of 4K, the width of each pixel island 100 can be designed to be 156μm. This is determined by the final display resolution of the display panel; the resolution number is the same as the number of pixel islands.

[0063] Correspondingly, the width of the microlens 10 is 52 μm, and the width of each sub-pixel group 150 is also 52 μm.

[0064] Correspondingly, the width G of the gap between adjacent sub-pixels 1 within the sub-pixel island 130 is 4μm, which is determined by the requirement that the sub-pixel spacing within the island be ≥4μm in the process of fabricating organic light-emitting diodes (OLEDs) using fine metal mask (FMM).

[0065] Accordingly, within the sub-pixel island 130, the width W of each sub-pixel 1 is 4μm, which is equal to the width G of the gap between adjacent sub-pixels.

[0066] In the same row, the spacing N between the sub-pixels of adjacent pixel islands 100 is 56μm, and the size of the spacing N is the width of the microlens 10 plus the width G of a sub-pixel gap.

[0067] Correspondingly, the width M of the gap between the dissimilar sub-pixel islands 130 located in different rows is 20 μm. This is determined by the requirement that the spacing between dissimilar sub-pixel islands be ≥20 μm in the process of fabricating organic light-emitting diodes (OLEDs) using fine metal mask (FMM).

[0068] Figure 9 This is a schematic diagram of the structure of pixel island 100 in a display panel according to another embodiment of this application. Other structures besides pixel island 100 can be the same as those in the above embodiment.

[0069] like Figure 9 Each pixel island 100 includes a plurality of sub-pixel islands 130 arranged along the second direction Y (column direction), of which three are shown in the embodiment: a first sub-pixel island 130R, a second sub-pixel island 130G, and a third sub-pixel island 130B. The first sub-pixel island 130R, the second sub-pixel island 130G, and the third sub-pixel island 130B are arranged sequentially along the column direction Y. Specifically, each sub-pixel 1a in the first sub-pixel island 130R emits red light, each sub-pixel 1b in the second sub-pixel island 130G emits green light, and each sub-pixel 1c in the third sub-pixel island 130B emits blue light.

[0070] Correspondingly, the light-emitting materials of sub-pixels 1 contained in the first sub-pixel island 130R, the second sub-pixel island 130G, and the third sub-pixel island 130B are different. Sub-pixel 1a of the first sub-pixel island 130R has an organic light-emitting material for emitting red light, sub-pixel 1b of the second sub-pixel island 130G has an organic light-emitting material for emitting green light, and sub-pixel 1c of the third sub-pixel island 130B has an organic light-emitting material for emitting blue light. Therefore, when depositing organic light-emitting materials using a fine metal mask (FMM) evaporation process, it is necessary to fabricate the material in three stages, depositing one type of organic light-emitting material of different colors each time.

[0071] The distribution and arrangement of subpixels within the first subpixel island 130R, the second subpixel island 130G, and the third subpixel island 130B are the same.

[0072] Figure 10 For more information on the layout of Pixel Island 100, please refer to [link / reference]. Figure 9 and Figure 10Each subpixel island 130 includes multiple subpixel groups 150 arranged along the row direction X. In the embodiment shown, there are three: a first subpixel group 150a, a second subpixel group 150b, and a third subpixel group 150c. The second subpixel group 150b is located between the first subpixel group 150a and the third subpixel group 150c. The number of subpixels 1 in each subpixel group 150a, 150b, and 150c may be unequal. The number of subpixel groups 150 is equal to the number of microlenses 10. The orthographic projection of each subpixel group 150 onto the lens array layer 11 falls within the same microlens 10.

[0073] Unlike the previous embodiments, the first sub-pixel group 150a, the second sub-pixel group 150b, and the third sub-pixel group 150c all have sub-pixels 1. Because an opaque area corresponding to the FMM process needs to be set, the number of sub-pixels 1 in the third sub-pixel group 150c is smaller. The opaque area is located within the third sub-pixel group 150c in a region far from the first sub-pixel group 150a and the second sub-pixel group 150b.

[0074] exist Figure 9 In the first subpixel group 150a, there are 6 subpixels 1 and 5 gaps (each gap is located between two adjacent subpixels); the second subpixel group 150b has 5 subpixels 1 and 6 gaps; the third subpixel group 150c has 2 subpixels 1 and 3 gaps (2 pixel gaps and 1 opaque area).

[0075] The positions and widths W of the five sub-pixels 1 in the second sub-pixel group 150b, and the positions and widths W of the two sub-pixels 1 in the third sub-pixel group 150c, respectively correspond to the positions and widths G of the five gaps in the first sub-pixel group 150a. Specifically, the first sub-pixel 1 in the second sub-pixel group 150b and the first sub-pixel 1 in the third sub-pixel group 150c correspond to two different regions of the first gap in the first sub-pixel group 150a, and after being superimposed, they fill the entire area of ​​the first gap. The second sub-pixel 1 in the second sub-pixel group 150b and the second sub-pixel 1 in the third sub-pixel group 150c correspond to two different regions of the second gap in the first sub-pixel group 150a, and after being superimposed, they fill the entire area of ​​the second gap. The third sub-pixel 1 in the second sub-pixel group 150b corresponds to the third gap in the first sub-pixel group 150a; their positions correspond, and their widths are the same. The fourth sub-pixel 1 in the second sub-pixel group 150b corresponds to the fourth gap in the first sub-pixel group 150a. The two are in the same position and have the same width. The fifth sub-pixel 1 in the second sub-pixel group 150b corresponds to the fifth gap in the first sub-pixel group 150a. The two are in the same position and have the same width.

[0076] The sum of the widths W of the five sub-pixels 1 in the second sub-pixel group 150b and the two sub-pixels 1 in the third sub-pixel group 150c is equal to the sum of the widths G of the five gaps in the first sub-pixel group 150a. This ensures that, after passing through the microlens 10, the light emitted by the sub-pixels 1 in the second and third sub-pixel groups 150b and 150c can well fill the area corresponding to the five gaps in the first sub-pixel group 150a, achieving continuity in the 3D display of this area.

[0077] Similarly, the positions and widths W of the six sub-pixels 1 in the first sub-pixel group 150a, and the positions and widths W of the two sub-pixels 1 in the third sub-pixel group 150c, correspond to the positions and widths G of the six gaps in the second sub-pixel group 150b, respectively. Specifically, the first sub-pixel 1 in the first sub-pixel group 150a and the first sub-pixel 1 in the third sub-pixel group 150c correspond to two different regions of the first gap in the second sub-pixel group 150b, and after being superimposed, they fill the entire region of the first gap. The second sub-pixel 1 in the first sub-pixel group 150a and the second sub-pixel 1 in the third sub-pixel group 150c correspond to two different regions of the second gap in the second sub-pixel group 150b, and after being superimposed, they fill the entire region of the second gap.

[0078] Similarly, the positions and widths W of the six sub-pixels 1 in the first sub-pixel group 150a, and the positions and widths W of the five sub-pixels 1 in the second sub-pixel group 150b, correspond to the positions and widths G of the three gaps in the third sub-pixel group 150c, respectively. Specifically, the first sub-pixel 1 in the first sub-pixel group 150a and the first sub-pixel 1 in the second sub-pixel group 150b correspond to two different regions of the first gap in the third sub-pixel group 150c, and after being superimposed, they fill the entire area of ​​the first gap. The second sub-pixel 1 in the first sub-pixel group 150a and the second sub-pixel 1 in the second sub-pixel group 150b correspond to two different regions of the second gap in the third sub-pixel group 150c, and after being superimposed, they fill the entire area of ​​the second gap. The 3rd to 6th sub-pixels 1 in the first sub-pixel group 150a and the 3rd to 5th sub-pixels 1 in the second sub-pixel group 150b correspond to two different regions of the 3rd gap in the third sub-pixel group 150c, and after being superimposed, they fill the entire region of the 3rd gap.

[0079] Due to manufacturing limitations, each sub-pixel group 150 cannot emit light continuously. In the embodiments described above, sub-pixels 1 from other sub-pixel groups 150 within the same sub-pixel island 130 are used to fill the light-emitting gaps within that sub-pixel group 150, thus making the discontinuously emitting sub-pixel group 150 equivalent to a continuously emitting pixel structure. Therefore, a continuous 3D display effect can be achieved.

[0080] Two adjacent pixel islands 100 located in the same row may not be at the same height in the column direction. This height difference can bring advantages in display effect. For example... Figure 10 The first pixel island 100a and the second pixel island 100b are not located at the same height, and the height difference between them can be approximately half the length of a single sub-pixel 1. The length of the sub-pixel 1 refers to the length of the sub-pixel 1 extending in the second direction.

[0081] In the height direction corresponding to the column direction, the third sub-pixel island 130B of the second pixel island 100b is lower than the first sub-pixel island 130R of the first pixel island 100a, but higher than the second sub-pixel island 130G of the first pixel island 100a, and is the farthest from the third sub-pixel island 130B of the first pixel island 100a. That is, for two adjacent pixel islands 100 in the same row, the sub-pixel islands 130 of the same color are farther apart in the aforementioned height direction.

[0082] Multiple first pixel islands 100a are arranged in odd-numbered columns, and multiple second pixel islands 100b are arranged in even-numbered columns. Each first pixel island 100a includes a first sub-pixel island 130R, a second sub-pixel island 130G, and a third sub-pixel island 130B arranged sequentially along the column direction. Each second pixel island 100b includes a third sub-pixel island 130B, a first sub-pixel island 130R, and a second sub-pixel island 130G arranged sequentially along the column direction. Furthermore, the second pixel islands 100b in even-numbered columns are lower than the first pixel islands 100a in odd-numbered columns by half the length of a single subpixel. This ensures that each sub-pixel island overlaps with two dissimilar sub-pixel islands of adjacent pixel islands in the height direction, while being far away from the same-color sub-pixel islands of adjacent pixel islands. The greater distance between the same-color sub-pixel islands in adjacent pixel islands is clearly beneficial to the FMM vapor deposition process.

[0083] For example, the third sub-pixel island 130B located in an even-numbered column overlaps with the first sub-pixel island 130R and the second sub-pixel island 130G located in odd-numbered columns in the column direction, while being far away from the same-color third sub-pixel island 130B located in an odd-numbered column. The first sub-pixel island 130R located in an even-numbered column overlaps with the second sub-pixel island 130G and the third sub-pixel island 130B located in odd-numbered columns in the column direction, while being far away from the same-color first sub-pixel island 130R located in an odd-numbered column. The second sub-pixel island 130G located in an even-numbered column overlaps with the third sub-pixel island 130B and the first sub-pixel island 130R located in odd-numbered columns in the column direction, while being far away from the same-color second sub-pixel island 130G located in an odd-numbered column.

[0084] Figure 11a and Figure 11b yes Figure 9 , Figure 10 The optical path diagram of the display panel, in which Figure 11byes Figure 11a A magnified view of a portion of the image. For example... Figure 11a and Figure 11b and combined Figure 9 , Figure 10 The five sub-pixels P2, P5, P8, P10, and P12 in the second sub-pixel group 150b, and the two sub-pixels P3 and P6 in the third sub-pixel group 150c, respectively fill the five gaps in the first sub-pixel group 150a (the gap between sub-pixels P1 and P4, the gap between sub-pixels P4 and P7, the gap between sub-pixels P7 and P9, the gap between sub-pixels P9 and P11, and the gap between sub-pixels P11 and P13). The final result is as follows: Figure 11a and Figure 11b The equivalent continuous light emission effect is shown. This pixel island structure design can increase the light coverage area of ​​the edge portion of the pixel island 100, thereby achieving continuous light emission, effectively eliminating moiré patterns, and ensuring display quality.

[0085] When the above pixel island array arrangement is applied to a 27-inch display panel with a resolution of 4K, the same as in the previous embodiment, the width of each pixel island 100 is designed to be 156μm, and correspondingly, the width of the microlens 10 is 52μm, and the width of each sub-pixel group 150 is 52μm.

[0086] Correspondingly, the width M of the gap between the dissimilar sub-pixel islands 130 located in different rows is 20 μm. This is determined by the requirement that the spacing between dissimilar sub-pixel islands be ≥20 μm in the process of fabricating organic light-emitting diodes (OLEDs) using fine metal mask (FMM).

[0087] Correspondingly, the width G of the gap between adjacent sub-pixels 1 in region 200 of sub-pixel island 130 is 4 μm, while outside region 200 of sub-pixel island 130, the width G of the gap between adjacent sub-pixels 1 is either 4 μm (sub-pixel spacing width is the sub-pixel width) or 8 μm (sub-pixel spacing width is twice the sub-pixel width). This is determined by the requirement that the sub-pixel spacing within the island be ≥4 μm in the process of fabricating organic light-emitting diodes (OLEDs) using a fine metal mask (FMM).

[0088] Accordingly, within the sub-pixel island 130, the width W of each sub-pixel 1 is 4μm.

[0089] Correspondingly, the spacing N between sub-pixels of the same color in adjacent pixel islands 100 is 53.85 μm, and the size of the spacing N is determined by half the sub-pixel height difference between two adjacent pixel islands 100 located in the same row in the column direction.

This embodiment can be implemented in a variety of forms and should not be limited to the scope of the description; the described features, structures, or characteristics can be combined in one or more embodiments with any suitable protection. The true scope and spirit of this application are indicated by the claims.
