In this embodiment, the first substrate 10 may be an array substrate of a display device, and the array substrate is an array substrate of any display device. The first substrate 10 includes a gate metal layer, a source-drain metal layer, a capacitor metal layer, an insulating layer and a semiconductor layer that are separated by each metal layer, and it should be noted that the film layer laminated structure of the first substrate is similar to the film layer laminated structure of the array substrate of any display device, and details and description thereof are omitted.
The image capturing unit 20 is disposed on one side of the first substrate 10, specifically, a thin film transistor array is disposed on the front surface of the first substrate 10, and the image capturing unit 20 is disposed on one side of the first substrate 10 away from the thin film transistor array. The image capturing unit 20 is any camera that can be integrated in a display device, specifically, a front camera of the display device, and captures an image on a display surface of the display device. One or more image capturing units 20 may be disposed in the display device, and the one or more image capturing units 20 may be disposed adjacently or at intervals. The structure, number and arrangement mode of the image acquisition units are not specifically limited in the invention.
In this embodiment, the display device includes a display area 30 and a non-display area 40 surrounding the display area 30, and the display area 30 is a complete display area, in which no non-display area or hollow area is provided, so that the display area 30 can completely display a picture, and the picture has no defect. A non-display region 40 is provided on the periphery of the display region 30, and a peripheral driver circuit of the display device and the like are provided in the non-display region 40, and a specific structure of the non-display region 40 will not be described in detail.
In this embodiment, the display area 30 includes a first display area 31 and a second display area 32 located at the periphery of the first display area 31, and the orthographic projection of the first display area 31 on the plane of the first substrate 10 covers the image capturing unit 20. The orthographic projection of the image acquisition unit 20 on the plane of the first substrate 10 is located in the display area 30, so that the installation mode of the image acquisition unit 20 does not occupy the area of the non-display area 40, the area of the non-display area can be reduced, the screen occupation ratio of the display device is improved, and the display device is beneficial to realizing a full screen. And the orthographic projection of the image acquisition unit 20 on the plane of the first substrate 10 is located in the display area 30, and no light-transmitting hole for transmitting light to the image acquisition unit 20 is arranged in the display area 30, so that the display area 30 is a whole body and can completely display pictures, and complete display of pictures of a full screen and a full screen is realized.
In this embodiment, the display region 30 includes a plurality of sub-pixels 50 arranged in an array, the plurality of sub-pixels 50 are located on a side of the first substrate 10 away from the image capturing unit 20, the sub-pixels located in the first display region 31 are defined as first sub-pixels 51, and the sub-pixels located in the second display region 32 are defined as second sub-pixels 52. The size of the first sub-pixel 51 in the first direction is smaller than the size of the second sub-pixel 52, and/or the size of the first sub-pixel 51 in the second direction is smaller than the size of the second sub-pixel 52, and the first direction intersects with the second direction.
The size of the first sub-pixel 51 is smaller than that of the second sub-pixel 52, that is, the size of the first sub-pixel 51 is compressed, and the area occupied by the arrangement of the lines, components, and the like in the corresponding first sub-pixel 51 is compressed. It is known that the transmittance of the circuit and the component is poor, and the area occupied by the circuit and the component in the first sub-pixel 51 is compressed, so that the area ratio of the low transmittance region in the first display region 31 is reduced, the area ratio of the high transmittance region in the first display region 31 is increased, and the transmittance and the aperture ratio of the first display region 31 are further increased. The light transmittance and the aperture opening ratio of the first display area 31 are large, then the external light can normally pass through the film layer where the sub-pixels are located and the first substrate 10 and enter the image acquisition unit 20 right below the first display area 31, and on the basis that the light through hole for the image acquisition unit 20 to pass light is not formed in the display area 30, the under-screen image acquisition of the image acquisition unit 20 is realized, and further, the full screen is realized. It should be noted that, the size of the compressed first sub-pixel 51 needs to ensure that the first display area 31 has a sufficient light transmittance and an aperture ratio to implement the under-screen image capture, so that relevant practitioners can reasonably design the size of the first sub-pixel 51 according to the product requirements on the basis of ensuring that the under-screen image capture and the normal display of the first sub-pixel can be implemented, and the size of the first sub-pixel is not specifically limited and described in the present invention.
Optionally, the sizes of any two first sub-pixels 51 in the first direction are the same, and the sizes of any two first sub-pixels 51 in the second direction are the same; and/or the size of any two second sub-pixels 52 in the first direction is the same, and the size of any two second sub-pixels 52 in the second direction is the same. In this embodiment, the selectable first sub-pixels 51 have the same size, so that the display brightness of the first display area 31 is uniform, and the selectable second sub-pixels 52 have the same size, so that the display brightness of the second display area 32 is uniform. In other embodiments, optionally, on the basis of ensuring the under-screen image capture, the size of the first sub-pixel may gradually increase from inside to outside; and/or the size of the second sub-pixel is gradually increased from inside to outside.
The optional second display area semi-surrounds the first display area or, as shown in fig. 2, the second display area 32 surrounds the first display area 31. The optional image capturing unit 20 may be disposed at an edge or a center of the corresponding display area 30, and the disposition position of the image capturing unit is not limited in the present invention. According to the different setting positions of the image capturing unit 20, the setting position of the first display area 31 changes accordingly, for example, if the image capturing unit is set at the edge of the corresponding display area, the first display area is located at the edge of the display area, and at this time, the second display area semi-surrounds the first display area. In this embodiment, the shape and size of the first display area 31 are not limited on the basis of ensuring that the orthographic projection of the first display area 31 on the plane where the first substrate 10 is located covers the image capturing unit 20. It should be noted that, in order to ensure the uniformity of the display brightness of the first display region, the first display region may be selected as a regular pattern, such as a circle, a square, etc.
In this embodiment, the film layer where the sub-pixels are located and the image acquisition unit are respectively disposed on two sides of the first substrate, the display area includes a first display area and a second display area, and the orthographic projection of the first display area on the plane where the first substrate is located covers the image acquisition unit; the size of the first sub-pixel of the first display area is smaller than that of the second sub-pixel of the second display area. In the embodiment, the orthographic projection of the image acquisition unit on the plane of the first substrate is positioned in the first display area, so that the area of a non-display area is not occupied, and a light through hole does not need to be dug in the display area for the image acquisition unit, so that the display area is a whole and can completely display a picture, the area of the non-display area can be reduced, and the screen occupation ratio is improved; the size of the first sub-pixel is compressed, so that the light transmittance and the aperture opening ratio of the first display area can be improved, and then the external light energy normally passes through the film layer where the sub-pixel is located and the first substrate to enter the image acquisition unit right below the first display area, so that the off-screen image acquisition of the image acquisition unit is realized. According to the embodiment, complete display of a full screen and a full screen picture is realized, and the problem that the image display of the existing full screen is defective is solved.
Illustratively, based on the above technical solution, as shown in fig. 7 and 8, the selectable display area 30 includes a third display area 33, the third display area 33 is located between the first display area 31 and the second display area 32, the sub-pixel 50 includes a plurality of third sub-pixels 53 located in the third display area 33, a size of the third sub-pixels 53 in the first direction is smaller than a size of the second sub-pixels 52 and larger than a size of the first sub-pixels 51, and/or a size of the third sub-pixels 53 in the second direction is smaller than a size of the second sub-pixels 52 and larger than a size of the first sub-pixels 52. In other embodiments, the size of the third sub-pixel in the first direction may be smaller than the size of the second sub-pixel and larger than the size of the first sub-pixel, and the size of the third sub-pixel in the second direction is equal to the size of the second sub-pixel or equal to the size of the first sub-pixel; it is further preferable that the size of the third sub-pixel in the second direction is smaller than the size of the second sub-pixel and larger than the size of the first sub-pixel, and the size of the third sub-pixel in the first direction is equal to the size of the second sub-pixel or equal to the size of the first sub-pixel.
In this embodiment, the orthographic projection of the optional first display area 31 overlaps with the image capturing unit 20, the third display area 33 is located on the periphery of the first display area 31, and the size of the third sub-pixel 53 is larger than that of the first sub-pixel 51, and the second display area 32 is located on the periphery of the third display area 33, and the size of the second sub-pixel 52 is larger than that of the third sub-pixel 53. Obviously, the size of the sub-pixels of the display area corresponding to the image capturing unit 20 and the display area around the display area forms a gradual compression, and the size of the sub-pixels 50 gradually increases from inside to outside, i.e. from the first display area 31, the third display area 33 to the second display area 32, so that the brightness of the first display area 31, the third display area 33 to the second display area 32 also gradually transitions. The gradual change of the size of the sub-pixels 50 can ensure that the brightness on the display area 30 is continuously and gradually changed, so that the phenomenon of obvious screen division can not occur, and the phenomena of display area boundary and obvious screen division caused by different brightness of the display area can be avoided.
As shown in fig. 8, at least two third sub-pixels 53 in the third display area 33 may be selected, a size of a third sub-pixel 53 far from the first display area 31 in the first direction is larger than that of a third sub-pixel 53 near the first display area 31, and/or a size of a third sub-pixel 53 far from the first display area 31 in the second direction is larger than that of a third sub-pixel 53 near the first display area 31. In other embodiments, any two third sub-pixels in the third display area may be selected, and a third sub-pixel 53 far from the first display area has a size in the first direction larger than that of a third sub-pixel near the first display area, and/or a third sub-pixel far from the first display area has a size in the second direction larger than that of a third sub-pixel near the first display area.
In the present embodiment, the size of the third sub-pixel 53 in the third display area 33 gradually increases from the inside to the outside direction, i.e., from the first display area 31 to the second display area 32 through the third display area 33. Obviously, the size of the third sub-pixel 53 of the third display area 33 forms a gradual change compression, and the brightness of the third display area 33 gradually changes over, so that the brightness of the third display area 53 is ensured to be continuously gradually changed; and from the first display area 31, the third display area 33 to the second display area 32, the size of the sub-pixel 50 is gradually increased, and then the brightness of the first display area 31, the third display area 33 to the second display area 32 is gradually changed. The display effect of the display device is further improved, and the phenomena of boundary and screen splitting caused by different brightness are avoided. In other embodiments, the sizes of the third sub-pixels of the third display area are all the same.
The third sub-pixels 53 surrounding the first display area 31 and located in the same turn in the optional third display area 33 as shown in fig. 9 are all the same in size in the first direction and are all the same in size in the second direction. In other embodiments, the size of each third sub-pixel in the third display area may be reasonably designed, and the size of the third sub-pixel is not particularly limited, for example, the size of the third sub-pixel far away from the first display area is larger than that of the third sub-pixel near the first display area, and the size of the third sub-pixel, for example, a circle, may be the same or different.
In this embodiment, each third sub-pixel 53 disposed adjacent to the edge of the first display area 31 forms a circle, that is, a first sub-pixel circle 53a, each third sub-pixel 53 disposed at the periphery of the first sub-pixel circle 53a and adjacent to the first sub-pixel circle 53a forms a circle, that is, a second sub-pixel circle 53a, each sub-pixel circle 53a surrounds the first display area 31, and so on, and the third display area 33 includes a plurality of sub-pixel circles 53a surrounding the first display area 31. It should be noted that the shape of the first display area may be a circle or a square or other shapes, and the shape of the sub-pixel circle may change with the change of the shape of the first display area, and the shape of the sub-pixel circle is also limited by the arrangement of the sub-pixels. For example, in the present embodiment, the sub-pixels 50 are arranged in an array, and when the first display region 31 is circular, the shape of the sub-pixel circle 53a is circular. In other embodiments, the sub-pixels of the third display area may be divided into regions, and the third sub-pixels of the same region have the same size.
In this embodiment, the sizes of the third sub-pixels 53 surrounding the first display area 31 and located in the same circle in the third display area 33 in the first direction are all the same, and the sizes in the second direction are all the same, so that the brightness of the sub-pixels 50 in one sub-pixel circle 53a is the same. In this embodiment, the size of the third sub-pixel 53 in the third display area 33 is smaller than the second sub-pixel 52 and larger than the first sub-pixel 51, and the size of the sub-pixel gradually increases from inside to outside, i.e. from the first display area 31, the third display area 33 to the second display area 32, so that the luminance of the first display area 31, the third display area 33 to the second display area 32 is gradually transited. The phenomenon of obvious screen splitting can not occur, and the phenomena of boundary and screen splitting caused by different brightness are avoided.
As shown in fig. 10, the optional third display area 33 includes at least two circles of third sub-pixels 53 surrounding the first display area 31, a circle of third sub-pixels 53 far from the first display area 31 has a size in the first direction larger than that of a circle of third sub-pixels 53 near the first display area 31, and/or a circle of third sub-pixels 53 far from the first display area 31 has a size in the second direction larger than that of a circle of third sub-pixels 53 near the first display area 31.
In this embodiment, the sub-pixel circle 53a in the third display area 33 is used as a unit to compress the size of the sub-pixel, and the size of the sub-pixel circle in the third display area 33 gradually increases from the inside to the outside. Obviously, the size of the third sub-pixel 53 of the third display area 33 forms a gradual change compression, and the brightness of the third display area 33 is in a gradual change transition, so that the brightness of the third display area 53 can be ensured to be continuously and gradually changed; and from the first display area 31, the third display area 33 to the second display area 32, the size of the sub-pixels is gradually increased, and then the brightness of the first display area 31, the third display area 33 to the second display area 32 is in continuous gradual transition. The display effect of the full-screen is further improved, and the phenomena of boundary and screen splitting caused by different brightness are avoided.
