It should be noted that the photosensitive element is aligned with the light-transmitting area, and the light-transmitting area may be multiple areas in order to obtain the light source sufficiently and enable the photosensitive element to detect the light source signal sufficiently. For example, the number of the light-transmitting regions is plural.
As further explained below with respect to the application of the display device to a display screen, in one embodiment, as shown in fig. 1 and 2, a display screen 10 is provided, which includes a display device including a light-transmissive cover plate 300 and a display panel 200 and a photosensitive element 100; one side of the display panel 200 is connected to the light-transmissive cover 300, for example, the light-transmissive cover 300 is connected to the side of the display panel 200 opposite to the photosensitive element 100.
As shown in fig. 2, the display panel 200 includes a wiring region 210 composed of pixel driving circuits and a plurality of light-transmitting regions 220 disposed between the pixel driving circuits, or the display panel 200 includes a wiring region 210 composed of pixel driving circuits and a plurality of light-transmitting regions 220 disposed between the wiring regions 210, the device 100 is disposed on a side of the display panel 200 facing away from the light-transmitting cover 300, and the light-sensing device 100 is aligned with the light-transmitting regions 220 in a direction perpendicular to the surface of the light-transmitting cover 300.
Specifically, the light-transmissive cover 300 is used for transmitting light, so that the light of the light source can be sequentially detected by the light-sensitive element 100 through the light-transmissive cover 300 and the light-transmissive region 220. The light-transmissive cover plate 300 is, for example, a glass cover plate. The glass cover plate has good light transmission performance, has insulation performance, can transmit light well, and can be effectively protected for the display panel 200.
The display panel 200 is an active Light Emitting display panel 200, for example, the display panel 200 is a quantum dot Light Emitting Diode (QLED) display panel, and the display panel 200 is an Organic Light-Emitting Diode (OLED) display panel. In this embodiment, the display panel 200 is an OLED display panel, the display panel 200 includes a pixel driving circuit, the pixel driving circuit includes a plurality of pixel light emitting units and a driving circuit, the pixel light emitting units include organic light emitting diodes, the pixel light emitting units are used for emitting light, the driving circuit is used for connecting a control module, specifically, the control module inputs a control signal to the driving circuit, and then controls the pixel light emitting units to emit light, and further enables the display panel 200 to perform light emitting display. The connection method and driving principle of the pixel light emitting unit and the driving circuit are prior art, and in this embodiment, the description is not repeated.
Specifically, as shown in fig. 3 and 4, the display panel 200 includes a wiring region 210 composed of the pixel driving circuit 211 and a light-transmitting region 220 disposed in a gap (a blank region) of the pixel driving circuit 211, and it is understood that the wiring of the driving circuit of the pixel driving circuit 211 may be wired according to a predetermined route such that the pixel driving circuit is routed at a predetermined position on the display panel 200 without wiring, and the blank region is formed at a position routed without wiring, such that the blank region formed by the wiring is the light-transmitting region 220, and for example, the pixel driving circuit 211 is wired according to a predetermined wiring image such that a plurality of light-transmitting regions 220 are formed on the display panel 200. For example, the pixel driving circuit includes a plurality of driving lines, and each of the light-transmitting regions 220 is disposed between the plurality of driving lines.
The light-transmitting area 220 can transmit light because it has no wiring of the pixel driving circuit, and the position where the pixel driving circuit exists is the wiring area 210, and the pixel driving circuit in the wiring area 210 will block light, so that the wiring area 210 is opaque. It should be understood that the light-transmissive region 220 may be understood as a light-transmissive hole, for example, the light-transmissive region 220 is a light-transmissive hole. In addition, the plurality of light-transmitting regions 220 may be distributed at any position on the display panel 200, that is, the light-sensing element 100 may be aligned at any position on the display panel 200. It should be noted that, since the area of the display panel 200 is much larger than the area of the photosensitive element 100, the photosensitive element 100 only needs to be aligned to a local position on the display panel 200, and a plurality of light-transmitting regions are disposed at the local position on the display panel 200, so as to transmit light to the photosensitive element 100.
It should be understood that the light source may be a natural light source or an artificial light source, for example, the light source is sunlight, for example, the light source is an illumination lamp, and for example, the light source is a pixel light emitting unit, and the light generated by the light source can be received by the photosensitive element 100, so that the photosensitive element 100 can shoot or perform fingerprint recognition according to the sensed light.
Because light is received through light-transmitting area 220 to photosensitive element 100, and then realize making a video recording or functions such as fingerprint identification, and need not additionally to occupy the display area that is used for installing display screen 10 on the terminal for display area on the display screen is bigger, thereby improves the screen proportion of taking up of the display screen on terminals such as electronic product.
In order to enable the photosensitive element 100 to uniformly and sufficiently receive the light of the light source, for example, the areas of the light-transmitting regions 220 are equally arranged, that is, the areas of the light-transmitting regions 220 are the same, and for example, the photosensitive element 100 is respectively aligned with the light-transmitting regions 220 at a plurality of positions. For example, the photosensitive element 100 includes a plurality of photosensitive sites, each of the photosensitive sites is aligned with one of the transparent regions 220, it should be understood that the photosensitive element 100 is an integral element having an area larger than that of one of the transparent regions 220, and the photosensitive element 100 receives light from the plurality of transparent regions 220 due to the larger area, so that the photosensitive element 100 can sufficiently receive the light from the light source by aligning the plurality of photosensitive sites on the photosensitive element 100 with the plurality of transparent regions 220.
In order to make the photosensitive element 100 have better photosensitive effect, for example, the display panel includes a plurality of pixel units, each pixel unit includes a pixel light emitting unit and a driving circuit, for example, a ratio of a width of the light transmitting area to a width of one pixel unit is 1: (10-20), for example, the ratio of the width of the light-transmitting area to the width of one pixel unit is 1: 10, for example, the ratio of the width of the light-transmitting region to the width of one pixel unit is 1: as another example, the ratio of the width of the light-transmitting region to the width of one pixel unit is 1: 15, it should be understood that the shape of the light-transmitting area is any one of a circle, a square and a regular polygon, the width of the light-transmitting area can be understood as the diameter of the light-transmitting area, or the maximum width or the average width of the light-transmitting area, and the width of the pixel unit is the maximum width of the pixel unit, for example, the size of the pixel unit of the mobile phone display screen is about 65 μm, the size of the pixel unit of the television display screen is about several hundreds of micrometers, for example, the size of the pixel unit is about 90 × 90 μm, that is, the width of the pixel unit is about 90 μm, so that the ratio of the width of the light-transmitting area to the width of the pixel unit is 1: (10 ~ 20) for the area in light-transmitting region is great, and light can penetrate and then be absorbed by the photosensitive element from light-transmitting region well, makes the sensitization effect of photosensitive element 100 better, in addition, can also avoid causing the influence to the luminescence of pixel cell, makes the luminous display effect of pixel cell better.
In order to enable the light sensing element 100 to uniformly receive the light of the light source, for example, each of the light transmitting regions 220 is equidistantly arranged, for example, each of the light transmitting regions 220 is arranged in a rectangular array of n rows and m columns, that is, the light transmitting regions 220 of each row are parallel to each other, the light transmitting regions 220 of each column are parallel to each other, the distance between two adjacent rows is equal, and the distance between two adjacent columns is equal, so that the light transmitting regions 220 are equidistantly and uniformly distributed on the display panel 200, and the light sensing element 100 can uniformly receive the light of the light source, and further perform photographing or fingerprint identification according to the sensed light.
In order to enable the photosensitive element 100 to uniformly receive the light of the light source, for example, the ratio of the distance between two adjacent light-transmitting regions 220 to the width of one pixel unit is 1: (0.2-1), that is, the ratio of the distance between two adjacent light-transmitting areas 220 in the same row to the width of one pixel unit is 1: (0.2-1), or the ratio of the distance between two adjacent light-transmitting areas 220 in the same row to the width of one pixel unit is 1: (0.2-1), that is, the distance between two adjacent light-transmitting areas 220 is 1 to 5 times the width of a pixel unit, it should be understood that the distance between the light-transmitting areas 220 is too small, the light-transmitting areas 220 are too dense, which is not favorable for the light-emitting display of the pixel unit, and the distance between the light-transmitting areas 220 is too large, which results in poor photosensitive effect of the photosensitive device 100, therefore, the ratio of the distance between two adjacent light-transmitting areas 220 to the width of a pixel unit is 1: (0.2-1), for example, the ratio of the distance between two adjacent light-transmitting regions 220 to the width of one pixel unit is 1: 1, or, a ratio of a distance between two adjacent light-transmitting regions 220 to a width of one pixel unit is 1: 0.5, the ratio of the distance between two adjacent light-transmitting regions 220 to the width of one pixel unit is 1: 0.2, so that the light sensing element 100 can uniformly receive the light of the light source, and the poor light emitting display effect of the pixel unit caused by the excessively dense light transmitting area can be avoided.
In order to enable the photosensitive element 100 to be connected with the display panel 200, for example, the display device further includes an adhesive layer 400, the photosensitive element 100 is connected with the display panel 200 through the adhesive layer 400, and for example, the photosensitive element 100 is connected with a side of the display panel 200 opposite to the glass cover plate through the adhesive layer 400. For example, the adhesive layer 400 is made of an adhesive material, for example, a glue, so that the photosensitive element 100 can be connected to the display panel 200 through the adhesive layer 400. In order to avoid blocking light and causing the photosensitive element 100 to not receive light well, for example, the adhesive layer 400 is offset from the light-transmitting region 220, that is, the adhesive layer 400 is disposed on the wiring region 210 of the display panel 200, that is, the adhesive layer 400 is aligned with the wiring region 210, or the adhesive layer 400 is aligned with a part of the wiring region 210, so that the adhesive layer 400 and the light-transmitting region 220 are offset from each other, blocking of light by the adhesive layer 400 is avoided, and the photosensitive element 100 can receive light well.
