[0035] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

In addition, in the context, it is also necessary to understand that when it is mentioned that an element is formed "on" or "under" another element, it can not only be formed directly "on" or "under" another element, but can also be formed indirectly "on" or "under" another element through an intermediate element. The terms "first", "second", etc. are only used for descriptive purposes and do not indicate any order, quantity or importance, but are only used to distinguish different components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0037] Figure 1 This is a schematic diagram of the structure of a display panel in the prior art. Figure 1 The display panel is a transparent display panel, comprising a display area 1. To achieve a transparent display, multiple light-transmitting apertures 2 are provided within the display area 1, allowing ambient light to pass through. Because the light-transmitting apertures 2 are arranged in an array, they can be considered a two-dimensional grating. When light passes through the multiple light-transmitting apertures 2, diffraction is significant, resulting in a blurred display. Some prior art solutions attempt to reduce diffraction by varying the shape and size of the light-transmitting apertures, but this can significantly impact light uniformity, compromising the transparent display effect.

[0038] In order to solve the above problems, an embodiment of the present invention provides a display panel, including a display area, at least part of the display area is a transparent display area; the transparent display area includes multiple sub-areas, the sub-areas are arranged in an array and have the same shape and area, the sub-areas include adjacent first and second sides, the first side of a sub-area is shared with a side of a sub-area adjacent in the first direction, and the second side is shared with a side of a sub-area adjacent in the second direction, wherein the first direction intersects the second direction, and the first direction intersects the first side; the sub-areas include non-transparent areas and transparent areas, the transparent areas have the same shape, the distance between the center of the transparent area and the first side of the sub-area is d1, the distance between the center of the transparent area and the second side of the sub-area is d2, and at least one of d1 and d2 is different in at least two sub-areas.

[0039] The embodiments of the present invention do not limit the type of display panel or the method of forming the light-transmitting area. For example, the display panel can be an organic light-emitting diode (OLED)-based display panel, a micro organic light-emitting diode (MicroLED)-based display panel, or a display panel integrating two or more light-emitting elements. The light-transmitting area can be formed by punching holes in a light-shielding layer or setting holes in a black pixel defining layer. The light-emitting elements are arranged in the non-light-transmitting area, and the specific location can be designed according to actual conditions.

[0040] For example, Figure 2 A schematic diagram of the structure of a display panel provided by an embodiment of the present invention. Figure 2 The display panel includes a display area 10, and the display area 10 includes a transparent display area 20, wherein Figure 2 The transparent display area 20 shown in the figure is only a part of the display area 10 and is only for illustration. In other embodiments, all display areas 10 can be set as transparent display areas. The transparent display area 20 includes a plurality of sub-areas 21 arranged in an array. The sub-areas 21 have the same shape and area. Figure 2 The schematic diagram shows that the shape of each sub-region 21 is a rectangle, which can be divided according to actual conditions during implementation. The sub-region 21 includes an adjacent first side 21a (the upper side of the rectangle) and a second side 21b (the right side of the rectangle). The first side 21a is shared with a side of the adjacent sub-region 21 in the first direction x (the lower side of the upper rectangle), and the second side 21b is shared with a side of the adjacent sub-region 21 in the second direction y (the left side of the right rectangle). That is, the transparent display area 20 is composed of multiple sub-regions 21 densely arranged and spliced. The first direction x intersects with the second direction y, and the first direction x intersects with the first side 21a. Each sub-region 21 includes a non-transparent area 211 and a transparent area 212, wherein the transparent areas 212 have the same shape, and the light transmission of each transparent area 212 tends to be consistent, which is conducive to improving the uniformity of light transmission. Figure 2It is schematically shown that the area of ​​each light-transmitting area 212 is also the same, which can ensure that the light-transmitting areas 212 adopt the largest designable area distribution, which is beneficial to improving the light transmittance. In other embodiments, at least some of the light-transmitting areas 212 can be set to have the same shape but different areas, that is, the light-transmitting areas 212 are similar. Setting the areas of the light-transmitting areas 212 to be different can increase the randomness of the design of the light-transmitting areas 212 and further reduce the diffraction of light. The distance between the center of the light-transmitting area 212 and the first side 21a of the sub-area 21 in which it is located is d1, and the distance between the center of the light-transmitting area 212 and the second side of the sub-area 21 in which it is located is d2. In this embodiment, at least one of d1 and d2 in at least two sub-areas 21 is different, that is, for two different sub-areas, the value of d1 can be set to be different, the value of d2 can be set to be different, or the values ​​of d1 and d2 can be designed to be different. Such a design can avoid the formation of a periodic grating in the light-transmitting area 212. For example Figure 2 The figure exemplarily shows that the transparent display area 20 includes 9 sub-areas, wherein d1 in the three sub-areas in the first row is different, d2 in the three sub-areas in the first column is different, and d1 and d2 in the sub-area in the first row and second column and the sub-area in the second row and first column are all different. Figure 2 In the embodiment shown, the centers of the sub-areas 21 in the first row and first column and the second row and second column coincide with the centers of the corresponding light-transmitting areas 212. When at least one of d1 and d2 is different, it can be considered that the centers of the light-transmitting areas are offset. Figure 2 The dashed box in the figure shows the outline of the light-transmitting area when it is located at the center of the sub-region. When the light-transmitting area moves in the positive or negative x-direction, d1 changes. When it moves in the positive or negative y-direction, d2 changes. When it moves in both directions, both d1 and d2 change. In a specific implementation, the values ​​of d1 and d2 can be randomly set within the allowable range. That is, the distribution of light-transmitting areas in the display area can be random without any specific pattern, to avoid the formation of a grating by multiple light-transmitting areas.

[0041] In other embodiments, only d1 in at least two sub-areas 21 may be set to be different, or only d2 may be set to be different, or both d1 and d2 may be different, or at least two of the above three situations may be included (for example, Figure 2 All three situations are included), and the specific implementation can be designed according to the actual situation. Figure 3 A schematic diagram of another display panel structure provided by an embodiment of the present invention. Taking the transparent display area including four sub-areas 21 as an example, refer to Figure 3, d1 in each sub-region 21 is different. The light-transmitting region 212 in the sub-region 21 of the first row and the first column is located at the center of the sub-region, and d1 remains unchanged; the light-transmitting region 212 in the sub-region 21 of the first row and the second column is moved in the positive x direction (upward) relative to the center position of the sub-region 21, and d1' < d1; the light-transmitting region 212 in the sub-region 21 of the second row and the first column is moved in the negative x direction (downward) relative to the center position of the sub-region 21, and d1'' > d1; the light-transmitting region 212 in the sub-region 21 of the second row and the second column is moved in the negative x direction (downward) relative to the center position of the sub-region 21, and d1''' > d1. Figure 4 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Refer to Figure 4 , d2 in each sub-region 21 is different. The light-transmitting region 212 in the sub-region 21 of the first row and the first column is located at the center of the sub-region, and d2 remains unchanged; the light-transmitting region 212 in the sub-region 21 of the first row and the second column is moved in the positive y direction (rightward) relative to the center position of the sub-region 21, and d2' < d2; the light-transmitting region 212 in the sub-region 21 of the second row and the first column is moved in the negative y direction (leftward) relative to the center position of the sub-region 21, and d2'' > d2; the light-transmitting region 212 in the sub-region 21 of the second row and the second column is moved in the negative y direction (leftward) relative to the center position of the sub-region 21, and d2''' < d2. Figure 5 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Refer to Figure 5 , both d1 and d2 in each sub-region 21 are different, Figure 5 The design method of the light-transmitting region in Figure 3 and Figure 4 is equivalent to the superposition of the design rules of the light-transmitting regions in

[0042] It should be noted that the shape of the sub-region in the above embodiments is only illustrative. In other embodiments, the sub-region can be set to other shapes, such as hexagon, triangle, etc. The shape of the corresponding light-transmitting region is not limited either. For example, the light-transmitting region can also be set to a circular shape, an oval shape, etc. Exemplarily, Figure 6 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Refer to Figure 6In this embodiment, the outline of each sub-region 21 and the light-transmitting region 212 is a hexagon. By setting at least one of d1 and d2 in at least two sub-regions 21 to be different, the randomness of the distribution of the light-transmitting region is increased, and the influence of diffraction when light passes through the light-transmitting region is reduced.

[0043] The technical solution of the embodiment of the present invention can achieve transparent display by setting a transparent display area or setting a photosensitive element in the transparent display area to achieve full-screen display. By setting multiple sub-areas in the transparent display area, the sub-areas include light-transmitting areas of the same shape, thereby improving the light transmittance uniformity of each light-transmitting area. By setting at least one of d1 and d2 in at least two sub-areas to be different, it is possible to avoid the formation of a fixed grating in the light-transmitting area, reduce the diffraction phenomenon when light passes through the light-transmitting area, improve the display effect of the transparent display area, or solve the problem of poor light quality received by the photosensitive element under the screen.

[0044] Optionally, the distance between the centers of two adjacent light-transmitting areas has at least two different values.

[0045] Among them, the transparent display area in this embodiment includes multiple densely spliced ​​sub-areas. The idea of ​​designing the light-transmitting area in this embodiment can be that the centers of different light-transmitting areas are located at different positions in the sub-areas where they are located. Therefore, the distance between the centers of two adjacent light-transmitting areas can be set to have at least two different values, so that the centers of the light-transmitting areas are randomly distributed within the preset range of the sub-areas where they are located. It is understandable that in some embodiments, when at least one of the values ​​of d1 and d2 is set to be different (in specific implementation, d1 of the two sub-areas can be different, d2 can be different, or both d1 and d2 can be different), it is also possible to make the distance between the centers of two adjacent light-transmitting areas at different positions the same, for example Figure 2 The distances between the center of the light-transmitting area of ​​the second row, second column subregion and the centers of the light-transmitting areas of the four adjacent subregions are c1, c2, c3, and c4, respectively. C2 and c4 are the same, while c1, c2, and c3 are different. While c2 and c4 are the same, d2 differs between the first subregion in the second row and the third subregion in the second row. The specific design of the light-transmitting area can be based on the center position of the light-transmitting area, or by changing at least the value of d1 or d2. This can be achieved by reducing the periodicity of the light-transmitting area.

[0046] Optionally, at least one of d1 and d2 in at least two adjacent sub-areas is different.

[0047] For example, continue to refer to Figure 2d1 is different between the first row, first column sub-region and the adjacent first row, second column sub-region; d2 is different between the first row, first column sub-region and the adjacent second row, first column sub-region; and both d1 and d2 are different between the third row, second column sub-region and the adjacent third row, third column sub-region. In other embodiments, d1 can be different only between at least two adjacent sub-regions, or only d2 can be different between two adjacent sub-regions, or both d1 and d2 can be different between two adjacent sub-regions. This arrangement helps increase the randomness of the distribution of the light-transmitting areas and is more conducive to reducing diffraction when the number of sub-regions is large. Furthermore, at least one of d1 and d2 can be different between any two adjacent sub-regions, that is, d1 is different, d2 is different, or both d1 and d2 are different between any two adjacent sub-regions. This can minimize the impact of diffraction. In specific implementations, the distribution of the light-transmitting areas can be designed based on actual conditions, and the distribution of the light-transmitting areas only needs to be random or approximately random.

[0048] In another embodiment, the light-transmitting area can be designed so that at least one of d1 and d2 conforms to a predetermined rule in a certain direction. Optionally, along at least one of the first and second directions, d1 within the sub-area varies according to a first rule, and / or d2 within the sub-area varies according to a second rule; the first rule includes m different values ​​of d1, and the second rule includes n different values ​​of d2, where m ≥ 2 and n ≥ 2, and both m and n are integers.

[0049] In a specific implementation, d1 can be designed to change according to a first rule along the first direction, d1 can be designed to change according to a first rule along the second direction, d1 can be designed to change according to a first rule along both the first and second directions (the first and second directions can be different specific rules), d2 can be designed to change according to a second rule along the first direction, d2 can be designed to change according to a second rule along the second direction, d2 can be designed to change according to a second rule along both the first and second directions (the first and second directions can be different specific rules), d1 can be designed to change according to the first rule along the first direction while d2 can change according to the second rule along the first or second direction, or d2 can change according to the second rule along both the first and second directions simultaneously, or d1 can be designed to change according to the first rule along the second direction while d2 can change according to the second rule along the first or second direction, or d2 can change according to the second rule along both the first and second directions simultaneously. The first and second rules can be designed based on actual conditions and are not limited in the embodiments of the present invention. For example, they can increase or decrease by a fixed value or a non-fixed value, change by a fixed ratio or a non-fixed ratio, etc. Optionally, in the first rule, the values ​​of m different d1s are in an arithmetic progression, and / or in the second rule, the values ​​of n different d2s are in an arithmetic progression. The first rule and the second rule can be selected according to actual conditions during implementation. That is, the values ​​of m different d1s can be in an arithmetic progression, the values ​​of n different d2s can be in an arithmetic progression, or the values ​​of m different d1s and n different d2s can be in an arithmetic progression. The selection can be made flexibly according to actual conditions during implementation.

[0050] For example, take m=n=3, and the first rule and the second rule are arithmetic changes. Figure 7 A schematic diagram of the structure of a transparent display area provided by an embodiment of the present invention. Figure 7 , along the first direction x (i.e., column direction), d1 in the sub-regions changes according to an arithmetic rule. Specifically, d1 in the first column sub-region and the third column sub-region increases arithmetic difference along the first direction x (for example Figure 7 The first column shows that d1 of the sub-area is d 10 d 10 +Δd,d 10 +2Δd, others are not shown), d1 in the second column of sub-regions decreases equidistantly along the first direction x, thereby reducing the diffraction of the light-transmitting area. Figure 8 This is a schematic diagram of another transparent display area provided by an embodiment of the present invention. Figure 8 , along the second direction y (i.e., row direction), d2 in the sub-area changes according to an arithmetic rule. Specifically, d2 in the first row sub-area and the third row sub-area increases arithmetic along the second direction y (e.g. Figure 8 The d2 of the first row of sub-areas is shown in d20 d 20 +Δd,d 20 +2Δd, others are not shown), d2 in the second row of sub-regions decreases equidistantly along the second direction y, thereby weakening the diffraction of the light-transmitting area. Figure 9 This is a structural diagram of another transparent display area provided by an embodiment of the present invention. Figure 9 , along the first direction x, d1 in the sub-region changes according to the arithmetic law, and along the second direction y, d2 in the sub-region also changes according to the arithmetic law, Figure 9 The variation pattern of the middle light transmission zone can be seen as Figure 7 and Figure 8 The values ​​of d1 and d2 corresponding to the movement of the light-transmitting area are not shown. In other embodiments, d1 may vary along the second direction y, d2 along the first direction x, or both d1 and d2 may vary simultaneously along the same direction x or the second direction y. This can be flexibly selected based on actual circumstances during implementation. By setting at least one of d1 and d2 to vary according to a preset rule, the values ​​of d1 and d2 at other locations can be calculated by designing a small number of initial values ​​of d1 and d2, while ensuring the random arrangement of the light-transmitting areas. This eliminates the need to design the values ​​of d1 and d2 for each individual d1 and d2, thereby simplifying the design of the light-transmitting areas.

[0051] In another embodiment, the changing rules of d1 and d2 may not be limited to one, for example, at least two sub-rules may be set to alternate. Optionally, along at least one of the first direction and the second direction, d1 in the sub-area changes according to a third rule, and / or d2 in the sub-area changes according to a fourth rule; the third rule includes a first sub-rule and a second sub-rule, the first sub-rule includes m1 different values ​​of d1, the second sub-rule includes m2 different values ​​of d1, the sub-area including the first sub-rule and the sub-area including the second sub-rule are alternately arranged, the fourth rule includes a third sub-rule and a fourth sub-rule, the third sub-rule includes n1 different values ​​of d2, the fourth sub-rule includes n2 different values ​​of d2, the sub-area including the third sub-rule and the sub-area including the fourth sub-rule are alternately arranged, m1≥2, m2≥2, n1≥2, n2≥2, and m1, m2, n1, and n2 are all integers.

[0052] In a specific implementation, d1 can be designed to change according to the third rule along the first direction, d1 can be designed to change according to the third rule along the second direction, d1 can be designed to change according to the third rule along both the first and second directions (the first and second directions can have different specific rules), d2 can be designed to change according to the fourth rule along the first direction, d2 can be designed to change according to the fourth rule along the second direction, d2 can be designed to change according to the fourth rule along both the first and second directions (the first and second directions can have different specific rules), d1 can be designed to change according to the third rule along the first direction while d2 can change according to the fourth rule along the first or second direction, or d2 can change according to the fourth rule along both the first and second directions, or d1 can be designed to change according to the third rule along the second direction while d2 can change according to the fourth rule along the first or second direction, or d2 can change according to the fourth rule along both the first and second directions. The third rule and the fourth rule can be designed based on actual conditions and are not limited in the embodiments of the present invention. Optionally, in the first sub-rule, the values ​​of m1 different d1s form an arithmetic progression, in the second sub-rule, the values ​​of m2 different d1s form an arithmetic progression; and / or in the third sub-rule, the values ​​of n1 different d2s form an arithmetic progression, and in the fourth sub-rule, the values ​​of n2 different d2s form an arithmetic progression. That is, only the first and second sub-rules can be set, only the third and fourth sub-rules can be set, or the first, second, third, and fourth sub-rules can be set simultaneously. By alternating the sub-rules, the randomness of the light-transmitting area can be increased without significantly increasing the design difficulty, thereby enhancing the anti-diffraction effect.

[0053] For example, take m1=m2=n1=n2=3 as an example, Figure 10 This is a structural diagram of another transparent display area provided by an embodiment of the present invention. Figure 10 , along the first direction x (i.e., the column direction), d1 in the sub-areas changes alternately according to two arithmetic progressions. Specifically, d1 in the first, third, and fifth sub-areas in the first, third, and fifth columns of sub-areas increase arithmetic progressions along the first direction x. That is, d1 in the first, third, and fifth sub-areas in the first, third, and fifth columns of sub-areas increase arithmetic progressions ( Figure 10 The figure shows that d1 in the first, third and fifth sub-areas of the first column are d 10 d 10 +Δd,d 10 +2Δd); d1 in the second, fourth, and sixth sub-areas of the first, third, and fifth columns of sub-areas decreases arithmetic steps along the first direction x, i.e., d1 in the second, fourth, and sixth sub-areas of the first, third, and fifth columns of sub-areas increases and decreases arithmetic steps ( Figure 10 It is shown that d1 in the second, fourth and sixth sub-areas of the first column is d′ 10, d′ 10 -Δd′, d′ 10 -2Δd′); d1 in the first, third, and fifth sub-regions of the second, fourth, and sixth columns of sub-regions decreases arithmetic steps along the first direction x, and d1 in the second, fourth, and sixth sub-regions of the second, fourth, and sixth columns of sub-regions increase arithmetic steps along the first direction x, thereby reducing diffraction in the light-transmitting area. Similarly, Figure 11 This is a structural diagram of another transparent display area provided by an embodiment of the present invention. Figure 11 , along the second direction y (i.e., the row direction), d2 in the sub-areas changes alternately according to two arithmetic progressions. Specifically, d2 in the first, third, and fifth sub-areas of the first, third, and fifth rows of the sub-areas increase arithmetic progressions along the second direction y. That is, d2 in the first, third, and fifth sub-areas of the first, third, and fifth rows of the sub-areas increase arithmetic progressions ( Figure 11 The figure shows that d2 in the first, third and fifth sub-areas of the first row are d 20 d 20 +Δd,d 20 +2Δd); d2 in the second, fourth, and sixth sub-areas of the first, third, and fifth rows of sub-areas decreases arithmetic steps along the second direction y, i.e., d2 in the second, fourth, and sixth sub-areas of the first, third, and fifth rows of sub-areas increases and decreases arithmetic steps ( Figure 11 The figure shows that d2 in the second, fourth, and sixth sub-areas of the first row are d′ 20 , d′ 20 -Δd′, d′ 20 -2Δd′); d2 in the first, third, and fifth sub-regions of the second row sub-region, the fourth row sub-region, and the sixth row sub-region decreases arithmetic progression along the second direction y, and d2 in the second, fourth, and sixth sub-regions of the second row sub-region, the fourth row sub-region, and the sixth row sub-region increases arithmetic progression along the second direction y, thereby weakening the diffraction of the light-transmitting area. Figure 12 This is a structural diagram of another transparent display area provided by an embodiment of the present invention. Figure 12 , along the first direction x, d1 in the sub-region changes alternately according to two arithmetic differences, and along the second direction y, d2 in the sub-region also changes alternately according to two arithmetic differences, which is equivalent to Figure 10 and Figure 11 In other embodiments, d1 may also vary along the second direction y, d2 may vary along the first direction x, or d1 and d2 may vary along the same direction x or the second direction y at the same time. Specific implementations may flexibly select the appropriate one based on actual conditions.

[0054] In other embodiments, the values ​​of d1 and d2 may vary according to other rules, or may vary randomly within a specified range without any specific rules, which is not limited in the embodiment of the present invention.

[0055] Optionally, in an embodiment of the present invention, the areas of the light-transmitting regions are equal. By setting the areas of the light-transmitting regions to be equal, it is possible to ensure that the transmittance of light to each light-transmitting region remains roughly consistent, ensuring that the light-transmitting regions are distributed with the largest area, and improving the uniformity of light transmission in the transparent display area.

[0056] In some embodiments, the transparent display area may occupy a larger area (for example, the entire display area is a transparent display area). In this case, the number of sub-areas is large. However, due to the need to set up light-emitting elements, pixel circuits, and other non-transparent area conditions, the values ​​of d1 and d2 are limited, and a completely random distribution of the transparent areas cannot be achieved. In this case, the transparent display area can be divided into multiple blocks, and the arrangement of the transparent areas in each block is the same or only some of the transparent areas are different. Optionally, the transparent display area includes at least two blocks, each block including a×b sub-areas arranged in an array; within the same block, at least one of d1 and d2 is different in at least two sub-areas; wherein a ≥ 2, b ≥ 2, and a and b are both integers.

[0057] The difference between at least one of the two sub-areas d1 and d2 is the same as the design in the above embodiment, which will not be described in detail here. Figure 13 This is a structural diagram of another transparent display area provided by an embodiment of the present invention. Figure 13 The transparent display area includes a plurality of blocks 200 ( Figure 13 Four blocks 200 are schematically shown in the figure, which is not a limitation of the embodiment of the present invention. In order to distinguish different blocks 200, gaps are shown between the blocks 200. Each block 200 includes a×b (in this embodiment, a=3, b=4 is taken as an example) sub-areas 21. In the same block 200, at least one of d1 and d2 is different ( Figure 13 d1 and d2 are not marked), that is, the light-transmitting areas 212 in the same block 200 are randomly distributed. The specific design of the light-transmitting areas 212 is similar to the above embodiment. For example, at least one of d1 or d2 can change according to an arithmetic progression.

[0058] Optionally, the transparent display area includes a block, d1 in the sub-area of ​​the i-th row and j-th column in all blocks is the same, and d2 in the sub-area of ​​the i-th row and j-th column in all blocks is the same; wherein i≤a, j≤b, and i and j are both integers.

[0059] For example, Figure 14 A schematic structural diagram of another transparent display area provided by an embodiment of the present invention is shown. Figure 14 Four blocks 200 are schematically shown in FIG. 1 , each block 200 includes 3×4 sub-regions 21 , and d1 and d2 are the same in the sub-region 21 at the same position (i.e., row i and column j) in each block 200 ( Figure 14 (d1 and d2 are not labeled). When the transparent display area includes a block, each block forms a minimum repeating unit, and the light-transmitting areas within the block are randomly arranged. Multiple blocks are repeatedly arranged to form a quasi-periodic arrangement of light-transmitting areas. This arrangement can reduce the design difficulty of the transparent display area while reducing diffraction.

[0060] Optionally, the transparent display area includes at least two types of blocks, and the two types of blocks include at least one different sub-area of ​​at least one of d1 and d2.

[0061] Figure 15 A schematic structural diagram of another transparent display area provided by an embodiment of the present invention is shown. Figure 15 It is schematically shown that the blocks in the first row and first column and the blocks in the second row and second column are the same type of blocks, and the blocks in the first row and second column and the blocks in the second row and first column are the same type of blocks. In other embodiments, more types of blocks can also be set. For example, the arrangement of the light-transmitting areas inside each block is different. Such a setting is close to a completely random distribution of the light-transmitting areas. When the number of blocks is greater than one, the randomness of the arrangement of the light-transmitting areas is better, which is more conducive to reducing the diffraction of light.

[0062] Optionally, a=b; within the same block, the combinations of d1 and d2 in the same sub-area include a types, and a types of combinations of d1 and d2 form a different sub-areas of a type; the sub-areas in the same row include a different sub-areas of a type, and the types of two adjacent sub-areas are different, and the sub-areas in the same column include a different sub-areas of a type, and the types of two adjacent sub-areas are different.

[0063] It can be understood that a combination of d1 and d2 corresponds to a setting mode of light-transmitting area, that is, a type of sub-area. In this embodiment, since the shape of each sub-area is the same, if at least one of d1 and d2 is different, the relative position of the light-transmitting area and the sub-area will be different. When designing the transparent display area, in order to make the light transmittance of each area relatively uniform, it is necessary to make the position distribution of the light-transmitting area in the sub-area relatively uniform. For example, taking a=b=3 as an example, Figure 16 A schematic diagram of the structure of three sub-areas provided in an embodiment of the present invention, wherein the three sub-areas are represented by A, B, and C respectively. The three sub-areas A, B, and C can form blocks with various different arrangements. For example, Figure 17 A schematic structural diagram of another transparent display area provided by an embodiment of the present invention is shown. Figure 17 Four different blocks 200 are shown.

[0064] Optionally, the block includes at least a! ×(a-1)! types, where a! represents the factorial of a and (a-1)! represents the factorial of a-1.

[0065] Among them, for a block including a×a sub-areas, when the combination of d1 and d2 includes a types, for example, when a=2, there are two types of light-transmitting areas that can be set in the sub-area of ​​the first row and the first column. Since the types of two adjacent sub-areas in the same row and the same column are different, when the sub-area of ​​the first row and the first column is determined, the arrangement of the blocks is determined, that is, there are two types of blocks when a=2. When a = 3, there are three types of light-transmitting areas that can be set in the first row and first column. The first row and second column cannot be the same as the first row and first column, and there are two types of light-transmitting areas that can be set. There is one type of light-transmitting area that can be set in the first row and third column. There are two types of light-transmitting areas that can be set in the second row and first column. There is one type of light-transmitting area that can be set in the third row and first column. Based on the arrangement of the light-transmitting areas in the first row and first column, there are 3 × 2 × 1 × 2 × 1 = 12 types of blocks. When a > 3, the light-transmitting areas that can be set in the first row and first column to the first row and a column are a, a-1, a-2, ..., and 1, respectively. The light-transmitting areas that can be set in the second row and first column to the a-th row and first column are a-1, a-2, ..., and 1, respectively. The second row and second column can also have multiple light-transmitting area arrangements, and so on. It can be seen that there are at least a! × (a-1)! types of block arrangements.

[0066] Figure 18 A schematic diagram of another sub-region structure provided by an embodiment of the present invention, Figure 19 A schematic diagram of the structure of another sub-area provided in an embodiment of the present invention. Figure 18 and Figure 19 Optionally, the sub-region 21 and the light-transmitting region 212 are both rectangular in shape, and at least two adjacent border regions of the sub-region 21 include a non-light-transmitting region 211; the first side 212a of the light-transmitting region 212 is adjacent to and parallel to the first side 21a of the sub-region 21, and the side length of the first side 212a of the light-transmitting region 212 is d 11 , the length of the first side 21a of the sub-region 21 is d 21 The second side 212b of the light-transmitting region 212 is adjacent to and parallel to the second side 21b of the sub-region 21, and the side length of the second side 212b of the light-transmitting region 212 is d 12 , the length of the second side 21b of the sub-region 21 is d 22 ;d 11 <d 21 , d 12 <d 22 , d 12 / 2≤d1≤d 22 -d 12 / 2,d 11 / 2≤d2≤d 21 -d 11 / 2.

[0067] In a specific implementation, the shape of the sub-region and the light-transmitting region can also be a rounded rectangle or other shape, and the first side of the light-transmitting region is approximately parallel to the first side of the sub-region. Since the light-transmitting region 212 is set inside the sub-region 21, the sub-region 21 needs to leave space for the non-light-transmitting region 211 to set up light-emitting elements, drive circuits, various wirings, etc., so the light-transmitting region 212 is smaller than the sub-region 21, that is, d is set. 11 <d 21 , d 12 <d 22 . refer to Figure 18 When the relative position of the light-transmitting area 212 and the sub-area 21 is that the light-transmitting area 21 is set at the upper left corner of the sub-area 21, d1 is the minimum value d 12 / 2, d2 is the maximum value d 21 -d 11 / 2, reference Figure 19 When the relative position of the light-transmitting area 212 and the sub-area 21 is that the light-transmitting area 21 is located at the lower right corner of the sub-area 21, d1 is the maximum value d 22 -d 12 / 2, d2 is the minimum value d 11 / 2, so the value of d1 satisfies d 12 / 2≤d1≤d 22 -d 12 / 2, the value of d2 satisfies d 11 / 2≤d2≤d 21 -d 11 / 2.

[0068] In this embodiment, each sub-region has a certain degree of transparency by setting a light-transmitting area within the sub-region. When the area of ​​the sub-region is fixed, the larger the area of ​​the light-transmitting area, the higher the light transmittance of the sub-region, and the smaller the area of ​​the light-transmitting area, the higher the light transmittance of the sub-region. In order to make the arrangement of the light-transmitting area have a certain degree of randomness, that is, d1 and d2 need to have a preset range of variation, the area of ​​the actual light-transmitting area needs to be slightly smaller than the maximum light-transmitting area that can be designed theoretically. Figure 18 and Figure 19 It can be seen that the maximum value of the change of d1 is d 22 -d 12 , the maximum value of the change of d2 is d 21 -d 11 In this embodiment, in order to balance the randomness and transmittance of the light-transmitting area, d 21 -d 11 <0.1×d 21 , d 22 -d 12 <0.1×d 22 , the area of ​​the light-transmitting region can be reduced to meet the random distribution of light transmittance while minimizing the transmittance loss.

[0069] Optionally, the maximum difference of d1 in two sub-regions is d 1max , the maximum difference of d2 in the two sub-regions is d 2max The maximum size of the light-transmitting area that can be set in the first direction of the sub-area is D1, and the maximum size of the light-transmitting area that can be set in the second direction of the sub-area is D2; d 1max <0.1×D2,d 2max <0.1×D1.

[0070] It is understandable that since the transparent display area also needs to be used for display, that is, the non-transparent area of ​​the sub-area needs to be provided with light-emitting elements, related driving circuits and circuit traces, the maximum difference in the variation of d1 (that is, the maximum difference in d1 between the two sub-areas) in actual design is d 1max than d 22 -d 12 To be smaller, the maximum size D2 of the light-transmitting area can be set to be smaller than d 22 The maximum value of the change of d2 (that is, the maximum difference of d2 in the two sub-areas) is d 2max than d 21 -d 11 To be smaller, the maximum size D1 of the light-transmitting area can be set to be smaller than d 21 To make it smaller, set d 1max <0.1×D2,d 2max <0.1×D1, that is It can be ensured that the transmittance of the light-transmitting areas after random distribution is greater than 81% before random distribution.

[0071] Optionally, the absolute value of the minimum non-zero difference between d1 in two different sub-regions is d 1min The absolute value of the minimum non-zero difference of d2 in two different sub-regions is d 2min , d 1min / d 22 >1%,d 2min / d 21 >1%.

[0072] By setting 1min / d 22 >1%,d 2min / d 21 >1%, which can ensure the variation of d1 and d2, ensure the randomness of the light-transmitting area design, and ensure a good diffraction reduction effect.

[0073] Optionally, the areas of the light-transmitting areas are equal; the transparent display area includes at least two blocks, each block includes 4×4 sub-areas, each block includes a first sub-area, a second sub-area, a third sub-area and a fourth sub-area, and in the first sub-area, d1=d 12 / 2, d2=d 21 -d 11 / 2, in the second sub-area, d1 = d 12 / 2, d2=d 11 / 2, in the third sub-area, d1=d 22 -d 12 / 2, d2=d 21 -d 11 / 2, in the fourth sub-area, d1 = d 22 -d 12 / 2, d2=d 11 / 2; any two adjacent sub-regions in the same row are of different types, and any two adjacent sub-regions in the same column are of different types.

[0074] For example, Figure 20 Schematic diagram of the structure of four types of sub-areas provided in the embodiment of the present invention. Figure 20 The four sub-regions are represented by D, E, F, and G respectively. In the first sub-region D, the light-transmitting area 212 is located at the upper left corner of the sub-region, that is, d1=d 12 / 2, d2=d 21 -d 11 / 2, in the second type of sub-region E, the light-transmitting area 212 is located at the upper right corner of the sub-region, that is, d1 = d 12 / 2, d2=d 11 / 2, in the third type of sub-region F, the light-transmitting area 212 is located at the lower left corner of the sub-region, that is, d1 = d 22 -d 12 / 2, d2=d 21 -d 11 / 2, in the fourth type of sub-region G, the light-transmitting area 212 is located at the lower right corner of the sub-region, that is, d1 = d 22 -d 12 / 2, d2=d 11 / 2. Figure 21 A schematic diagram of another transparent display area provided by an embodiment of the present invention. Figure 21 Four blocks 200 are shown in FIG. 1 , and each block 200 is arranged in a different manner, so that the position distribution of the light-transmitting area in the sub-area is relatively uniform, achieving uniform overall light transmittance and avoiding the effect of some areas being too bright or too dark. Figure 21 The four types of blocks shown in FIG are only exemplary. As can be seen from the above embodiments, there are at least 4×3×2×1×3×2×1=144 types of blocks.

[0075] Similarly, the sub-areas can also include six types of sub-areas. Optionally, the areas of the light-transmitting areas are equal; the transparent display area includes at least two blocks, each block includes 6×6 sub-areas, each block includes the fifth sub-area, the sixth sub-area, the seventh sub-area, the eighth sub-area, the ninth sub-area and the tenth sub-area, and in the fifth sub-area, d1=d 12 / 2, d2=d 21 -d 11 / 2, in the sixth sub-area, d1=d 12 / 2, d2=d 21 / 2, in the seventh sub-area, d1 = d 12 / 2, d2=d 11 / 2, in the eighth sub-area, d1 = d 22 -d 12 / 2, d2=d 21 -d 11 / 2, in the ninth sub-area, d1 = d 22 -d 12 / 2, d2=d 21 / 2, in the tenth sub-area, d1 = d 22 -d 12 / 2, d2=d 11 / 2; any two adjacent sub-regions in the same row are of different types, and any two adjacent sub-regions in the same column are of different types.

[0076] For example, Figure 22 Schematic diagram of the structure of six types of sub-areas provided by the embodiment of the present invention. Figure 22 The six sub-regions are represented by H, I, J, K, L, and M respectively. In the fifth sub-region H, the light-transmitting area 212 is located at the upper left corner of the sub-region, that is, d1 = d 12 / 2, d2=d 21 -d 11 / 2, in the sixth type of sub-region I, the light-transmitting area 212 is located in the upper middle position of the sub-region, that is, d1 = d 12 / 2, d2=d 21 / 2, in the seventh sub-region J, the light-transmitting area 212 is located at the upper right corner of the sub-region, that is, d1 = d 12 / 2, d2=d 11 / 2, in the eighth type of sub-region K, the light-transmitting area 212 is located at the lower left corner of the sub-region, that is, d1 = d 22 -d 12 / 2, d2=d 21 -d 11 / 2, in the ninth type of sub-region L, sub-region 212 is located in the middle and lower position of the sub-region, that is, d1 = d 22 -d 12 / 2, d2=d 21 / 2, in the tenth type of sub-region M, the sub-region 212 is located at the lower right corner of the sub-region, that is, d1 = d 22 -d 12 / 2, d2=d 11 / 2. Figure 23 A schematic diagram of another transparent display area provided by an embodiment of the present invention. Figure 23 Four blocks 200 are shown in FIG. 1 , and each block 200 is arranged in a different manner, so that the position distribution of the light-transmitting area in the sub-area is relatively uniform, achieving uniform overall light transmittance and avoiding the effect of some areas being too bright or too dark. Figure 23 The four types of blocks shown in FIG are only exemplary. As can be seen from the above embodiments, the types of blocks include at least 6×5×4×3×2×1×5×4×3×2×1=86400.

[0077] It should be noted that the above-mentioned types of sub-areas are only illustrative examples. In other embodiments, a block may include other numbers of different types of sub-areas. Different combinations of d1 and d2 can form more different types of sub-areas. The specific implementation can be designed according to actual conditions.

Figure 24 Optionally, the display area 10 further includes a conventional display area 30, and the transparent display area 20 is multiplexed as a light sensing element setting area.

[0079] The light-sensing element can be a camera, and the display panel can realize a full-screen display of the under-screen camera. In a specific implementation, the display panel can include a light-emitting element, such as OLED or Micro LED. It can also be provided with two light-emitting elements. For example, the conventional display area 30 includes OLED, and the transparent display area 20 includes a smaller Micro LED, which is beneficial to the design of the light-transmitting area.

Figure 25 Optionally, the display area 10 is a transparent display area 20. This setting can form a full-screen transparent display, for example, it can be used in applications such as transparent televisions, windows, and display cabinets.

[0081] In other embodiments, a first film layer may be further provided in the transparent display area; for different light-transmitting areas, at least one of the following conditions exists: 1) the thickness of the first film layer is different; 2) the material of the first film layer is different; 3) the first film layer includes at least two stacked sub-film layers, and the thickness ratios of the sub-film layers are different. In this way, the optical path or phase difference of external light when passing through the light-transmitting area can be adjusted, thereby further reducing the influence of diffraction.

The material of the single-layer film layer can be an organic material; Scenario 2, the first film layer is a multi-layer stacked film layer, and the first film layer contains different numbers of film layers in different light-transmitting areas, thereby having different thicknesses in different light-transmitting areas. The material of the film layers contained in the first film layer may include inorganic materials and organic materials; Scenario 3, the film layers in the first film layer simultaneously contain single-layer film layers with different thicknesses in different light-transmitting areas and multi-layer film layers with different numbers of film layers in different light-transmitting areas.

[0084] The first film layer includes at least two stacked sub-film layers, and the sub-film layers have different thickness ratios. For example, the first film layer includes a first sub-film layer and a second sub-film layer stacked together, and the light-transmitting area includes a first light-transmitting area and a second light-transmitting area, wherein the thickness of the first sub-film layer in the first light-transmitting area is greater than the thickness in the second light-transmitting area, and the thickness of the second sub-film layer in the first light-transmitting area is less than the thickness in the second light-transmitting area.
