[0001] This application belongs to the field of communication technologies, and particularly relates to a display screen structure and an electronic device. Background Art
[0002] With the development of Organic Light-Emitting Diode (OLED) display screens, in order to optimize power consumption and improve battery life, the industry has currently developed a technical solution to remove the polarizer, which can release the OLED light absorbed by the polarizer, thereby effectively increasing the light output of the OLED to achieve the purpose of reducing power consumption.
[0003] For terminals without a polarizer, an under-screen sensor is used to adjust the brightness and color temperature of the mobile phone in different environments, making the display clearer and the user's eyes more comfortable when using the mobile phone. However, in real mobile phone usage scenarios, the angle between the user's mobile phone and the ambient light source may change at any time. In the same environment, when the angle between the user's mobile phone and the ambient light source changes, the difference in ambient light transmittance is relatively large, which will cause the under-screen sensor to inaccurately adjust the brightness and color temperature in the same environment. Summary of the Invention

[0032] The motor structure according to an embodiment of the present application will be described below with reference to the accompanying drawings.
[0033] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a display screen structure, including:
[0034] a display panel 1 and a photosensitive element 2 located on one side of the display panel 1;
[0035] Wherein, at least one light-transmitting area 12 is provided in the first area of the display panel 1, and the cross-section of the light-transmitting area 12 has a preset shape, and / or, the light-transmitting area 12 forms a preset angle with respect to the center line of the display panel 1; the first area is the area of the display panel 1 opposite to the photosensitive element 2.
[0036] In this embodiment, the display panel 1 may be a display panel without a polarizer (Polarizer less, Polless). A photosensitive element 2 is provided on one side of the display panel 1, and the photosensitive element may be a photosensitive sensor. The first area of the display panel 1 corresponds to the photosensitive element 2, and it can also be understood that the photosensitive element 2 is correspondingly arranged with the first area of the display panel 1. For example: there is a light-transmitting hole corresponding to a camera on the display panel 1, and a lens is provided in the light-transmitting hole. Inside the electronic device, the camera is arranged opposite to the light-transmitting hole. A photosensitive element 2 is arranged at a position adjacent to the camera, then the first area is the area of the display panel 1 adjacent to the light-transmitting hole of the camera, and the projection of the first area is located on the photosensitive element 2, so as to ensure that external ambient light can enter the photosensitive element 2 through the light-transmitting area 12 of the first area.
[0037] As Figure 1 shown is a plan view of the first area. One or more light-transmitting areas 12 can be provided in the first area. In the direction parallel to the display panel 1, the cross-section of the light-transmitting area 12 has a preset shape. Optionally, the preset shape may be a polygon, a circle, an ellipse, etc. For example Figure 1 the rectangle shown in Figure 7 the cross shape shown in Figure 8 the rhombus shown in Figure 9 the star shape shown inFigure 10 The triangle shown, Figure 11 The trapezoidal shape shown, etc., can help increase the incident angle of ambient light reaching the under-screen sensor. It should be noted that within the first region, the shapes of the multiple light-transmitting areas 12 can be the same or different, and this is not limited here. By setting the shape of the light-transmitting area 12 to a preset shape, it can be ensured that even after the relative angle between the electronic device and the ambient light source changes, more light can still pass through the light-transmitting area and enter the photosensitive element 2, ensuring that the photosensitive element accurately judges the ambient light, thereby accurately adjusting the screen brightness and color temperature.
[0038] The angle between the light-transmitting areas 12 and the center line of the display panel can also be set to a preset angle. Optionally, the preset angle can range from -180 degrees to 180 degrees. Optionally, within the first area, the angles of the multiple light-transmitting areas 12 relative to the center line of the display panel 1 can be the same or different. The center line of the display panel here can refer to Figure 1 The vertical center line shown can also be Figure 1 For example, if the center line of the display panel is as shown in the horizontal direction. Figure 1 The vertical center line shown, such as Figure 1 As shown, the angle between the first light-transmitting area 12 in the first row and the center line is 0 degrees, the angle between the second light-transmitting area 12 in the first row and the center line is 45 degrees, the angle between the third light-transmitting area 12 in the first row and the center line is 90 degrees, and the angle between the fourth light-transmitting area 12 in the first row and the center line is -45 degrees. By setting the angle between the light-transmitting area 12 and the center line of the display panel 1 to a preset angle, even when the relative angle between the electronic device and the ambient light source changes, the angle setting of the light-transmitting area ensures that more light can pass through the light-transmitting area and enter the photosensitive element 2, ensuring that the photosensitive element accurately determines the ambient light, thereby accurately adjusting the screen brightness and color temperature.
[0039] In an embodiment of the present application, one or more light-transmitting areas are arranged in the first area of the display panel, and the interface of the light-transmitting area is in a preset shape, and / or the light-transmitting area is at a preset angle relative to the center line of the display panel. This can ensure that after the relative angle between the electronic device and the ambient light source changes, more light can still pass through the light-transmitting area and enter the photosensitive element, thereby ensuring that the photosensitive element accurately judges the ambient light, thereby accurately adjusting the screen brightness and color temperature.
[0040] As an alternative embodiment, when there are multiple light-transmitting regions 12, at least some of the multiple light-transmitting regions 12 are regularly arranged within the target region; the target region is a partial region of the first region, or the target region is the entire region of the first region.
[0041] In this embodiment, the target region can be a partial region of the first region, and the light-transmitting regions 12 within this partial region can be regularly arranged. Or, the target region can also be the entire region of the first region, which can be understood as all the light-transmitting regions within the first region being regularly arranged. The so-called regular arrangement herein can include at least one of the following: the distribution positions of the light-transmitting regions 12 are arranged according to a certain rule; the shapes of the light-transmitting regions 12 are arranged according to a certain rule; the angles of the light-transmitting regions 12 relative to the center line of the display panel 1 are arranged according to a certain rule. By regularly setting the light-transmitting regions 12, not only can it be ensured that the display panel has sufficient light transmittance at various relative angles between the electronic device and the ambient light source, but also it is convenient for the preparation and molding of the display panel.
[0042] Optionally, the target region includes M sub-regions, where M is greater than or equal to 1;
[0043] Within at least some of the sub-regions, the light-transmitting regions 12 are arranged according to a preset arrangement manner, and the light-transmitting regions 12 within the target region are topologically arranged according to the arrangement of the light-transmitting regions 12 within the sub-regions;
[0044] and / or,
[0045] Within at least some of the sub-regions, the angles of the light-transmitting regions 12 relative to the center line of the display panel 1 change according to a preset angle value, and the light-transmitting regions 12 within the target region are topologically arranged according to the arrangement of the light-transmitting regions 12 within the sub-regions.
[0046] In this embodiment, the target region can be divided into one or more sub-regions. For example, the target region can be divided into four sub-regions of up, down, left, and right, or the target region can be divided into nine equally divided sub-regions. The size of each sub-region can be the same or different, and the division method of the target region is not limited herein.
[0047] Within at least some of the sub-regions, the light-transmitting regions 12 are arranged according to a preset arrangement manner. Within each sub-region, the arrangement manners of the light-transmitting regions 12 can be the same or different. For example: the target region is divided into 4 sub-regions, and the light-transmitting regions 12 within 2 of the sub-regions are regularly arranged according to a preset arrangement manner, and the arrangement manners of the light-transmitting regions 12 within these 2 sub-regions are the same. The arrangement manners of the light-transmitting regions 12 within the other 2 sub-regions are not limited and can be irregular. The light-transmitting regions within the target region are topologically arranged according to the arrangement of the light-transmitting regions 12 in each sub-region.
[0048] This design method can ensure that at least some of the light-transmitting regions 12 in the first region are regularly arranged, facilitating the design of the light-transmitting regions and the preparation and shaping of the display panel.
[0049] Optionally, the display panel 1 includes pixel units 11 arranged in an array;
[0050] The preset arrangement method includes at least one of the following:
[0051] The light-transmitting region 12 is located between two adjacent pixel units 11 in a row;
[0052] The light-transmitting region 12 is located between two adjacent pixel units 11 in a column;
[0053] The light-transmitting region 12 is located between two adjacent pixel units 11 distributed diagonally.
[0054] As Figure 1 Or Figure 2 shown, the display panel 1 includes pixel units 11 arranged in an array, and the pixel units 11 can be pixel units composed of organic light-emitting diodes (OLEDs). The pixel units 11 on this display panel can include pixel units that emit red light, pixel units that emit green light, and pixel units that emit blue light. The three-color light pixel units are arranged in an array, as Figure 1 shown.
[0055] In the first region, the light-transmitting region 12 can be arranged between two adjacent pixel units 11 in a row. For example, Figure 1 shown, the light-transmitting region 12 is arranged between the pixel units in the first row, the third row, the fifth row, and the seventh row. The light-transmitting region 12 can also be arranged between two adjacent pixel units 11 in a column. For example, Figure 1 shown, the light-transmitting region 12 is arranged between the pixel units in the second column, the fourth column, the sixth column, and the eighth column. The light-transmitting region 12 can also be arranged between two adjacent pixel units 11 distributed diagonally.
[0056] The light-transmitting region 12 is arranged between two adjacent pixel units 11 as Figure 2 shown. In the first region opposite to the photosensitive element 2, a light-transmitting region 12 is arranged between two adjacent pixel units 11. Optionally, multiple light-transmitting regions 12 can be evenly distributed or arranged according to a preset arrangement method, and ambient light can be transmitted to the photosensitive element 2 through the light-transmitting regions, and the photosensitive element 2 processes the received light.
[0057] The setting position of the light-transmitting region 12 can be determined based on the distance between two adjacent pixel units 11. For example, in a row of pixel units, the distance between two adjacent pixel units 11 is small, and it is impossible to open the light-transmitting region 12; the distance between two adjacent pixel units 11 distributed diagonally is large, meeting the size design requirements of the light-transmitting region 12, then the light-transmitting region 12 can be set between two adjacent pixel units 11 distributed diagonally.
[0058] Optionally, within at least some of the sub-regions, the shapes of the light-transmitting regions 12 can also be arranged according to a preset rule. For example: the target region is divided into 4 sub-regions, where the light-transmitting regions 12 in the 1st and 2nd sub-regions are rectangles, and the light-transmitting regions 12 in the 3rd and 4th sub-regions are triangles. Or, the light-transmitting regions 12 in each sub-region are all different, being rectangles, triangles, rhombuses, and trapezoids respectively. Another example: the light-transmitting regions 12 in the 1st and 2nd sub-regions are arranged in a cross pattern of rectangles and triangles; the light-transmitting regions 12 in the 3rd and 4th sub-regions are arranged in a cross pattern of rhombuses and trapezoids.
[0059] In the direction parallel to the display panel 1, the cross-section of the light-transmitting region 12 has a preset shape, such as a rectangle, trapezoid, triangle, star, etc. This preset shape needs to satisfy the interval between two adjacent pixel units 11 and ensure that ambient light can enter the photosensitive element 2. In one embodiment, within the same sub-region, the shapes of two adjacent light-transmitting regions 12 can be different. For example: from left to right, they are rectangle, trapezoid, triangle, etc., and can be arranged periodically. By setting adjacent light-transmitting regions to different shapes, it can be ensured that there must be light transmitted to the photosensitive element 2 in areas with similar positions. For example: two adjacent light-transmitting regions are a rectangle and a star. Under the same ambient brightness, due to the change in the relative angle between the electronic device and the ambient light source, light cannot pass through the rectangular light-transmitting region, or only a small part of the light can pass through the rectangular light-transmitting region. However, for the adjacent light-transmitting region which is a star, according to the shape characteristics of the star, the star-shaped light-transmitting region contains regions extending at multiple angles. After the relative angle between the electronic device and the ambient light source changes, there can still be more light passing through and entering the photosensitive element 2, ensuring the accurate judgment of ambient light by the photosensitive element.
[0060] It should be noted that the shape and arrangement method of the light-transmitting region can be set according to design requirements, and the shape arrangement method of the light-transmitting region 12 is not listed one by one here.
[0061] Within at least some sub-regions, for different sub-regions, the angles of the light-transmitting regions 12 relative to the center line of the display panel 1 can be different. Topology can be performed on the arrangements of the light-transmitting regions 12 in multiple sub-regions to obtain the arrangement of the light-transmitting regions within the target region.
[0062] Optionally, the angle of the light-transmitting region 12 relative to the center line of the display panel 1 changes according to a preset angle value, including: in the target region, there are at least two sub-regions, and the angle of the light-transmitting region 12 in one sub-region relative to the center line of the display panel 1 is different from the angle of the light-transmitting region 12 in another sub-region.
[0063] In some embodiments, for different sub-regions, the angles of the light-transmitting regions 12 relative to the center line of the display panel may be the same or different. For example: the target region includes 4 sub-regions, and among them, the angles of the light-transmitting regions 12 in these 4 sub-regions relative to the center line of the display panel are all different. For instance, the angles of the light-transmitting regions 12 in the 4 sub-regions relative to the center line of the display panel are a degrees, b degrees, c degrees, and d degrees respectively, and the values of a, b, c, and d are all different. The difference between the angles of the light-transmitting regions in two sub-regions relative to the center line of the display panel is a preset angle, and the preset angle may include multiple values, and the differences between different sub-regions may be the same or different.
[0064] As an optional embodiment, for different sub-regions, according to the arrangement order of the sub-regions, the light-transmitting regions 12 in each sub-region can be rotated by a first angle value in sequence. Among them, the range of the first angle value can be -180 degrees to 180 degrees. For example: the target region is divided into 4 sub-regions, and among them, the angle of the light-transmitting region 12 in the first sub-region relative to the center line of the display panel is 0 degree, the angle of the light-transmitting region 12 in the second sub-region relative to the center line of the display panel is 45 degrees, the angle of the light-transmitting region 12 in the third sub-region relative to the center line of the display panel is 90 degrees, and the angle of the light-transmitting region 12 in the fourth sub-region relative to the center line of the display panel is -45 degrees. The light-transmitting regions 12 are rotated by 45 degrees in sequence from the first sub-region to the fourth sub-region. By setting the included angles of the light-transmitting regions 12 in different sub-regions relative to the center line of the display panel to different values, it can be ensured that after the relative angle between the electronic device and the ambient light source changes, more light can still pass through and enter the photosensitive element 2, ensuring the accurate judgment of the ambient light by the photosensitive element.
[0065] Optionally, the angle of the light-transmitting region 12 relative to the center line of the display panel 1 changes according to a preset angle value, including: in the same sub-region, there are at least two angles of the light-transmitting regions 12 relative to the center line of the display panel 1 that are different.
[0066] In some of these embodiments, for multiple light-transmitting regions 12 in the same sub-region, the angles of the light-transmitting regions 12 relative to the center line of the display panel may be the same or different. For example Figure 3As shown, it represents a case where the angles of multiple light-transmitting regions 12 within a sub-region with respect to the center line of the display panel are all 90 degrees; for another example Figure 1 As shown, it represents a case where the angles of multiple light-transmitting regions 12 within a sub-region with respect to the center line of the display panel are different.
[0067] As an optional embodiment, it can be set that the angles of multiple light-transmitting regions 12 within a sub-region rotate in sequence according to a second angle value, and the range of the second angle value is from -180 degrees to 180 degrees. For example: as Figure 1 As shown, the light-transmitting regions 12 are all rectangular. The set angles of the first light-transmitting region 12 and the second light-transmitting region 12 in the first row are different. The first light-transmitting region 12 is parallel to the vertical center line of the display panel 1, which can also be understood as the angle between the first light-transmitting region 12 and the vertical center line of the display panel 1 is 0; the second light-transmitting region 12 has an included angle with the vertical center line of the display panel 1, which can be 45 degrees; the third light-transmitting region 12 is perpendicular to the vertical center line of the display panel 1, and the included angle is 90 degrees; the included angle between the fourth light-transmitting region 12 and the vertical center line of the display panel 1 is -45 degrees. The light-transmitting regions 12 rotate 45 degrees in sequence according to the arrangement order.
[0068] It should be noted that the rotation angles here are only examples, and the first angle value and / or the second angle value can also be set to other values, such as 22.5 degrees, 30 degrees, and so on.
[0069] In this embodiment, since the arrangement angles of the multiple light-transmitting regions 12 are different, after the relative angle between the electronic device and the ambient light source changes, there can still be more light passing through and entering the photosensitive element 2, ensuring the accurate judgment of the ambient light by the photosensitive element.
[0070] In the embodiment of the present application, the display panel includes multiple pixel units distributed in an array, and a light-transmitting region is provided between two adjacent pixel units, and the ambient light enters the photosensitive element through the light-transmitting region. Among them, the shapes of the multiple light-transmitting regions within a sub-region can be different, and / or the set angles of the light-transmitting regions within a sub-region with respect to the center line of the display panel are different, which can ensure that after the relative angle between the electronic device and the ambient light source changes, there can still be more light passing through and entering the photosensitive element, ensuring the accurate judgment of the ambient light by the photosensitive element, and thus accurately adjusting the screen brightness and color temperature.
[0071] As an optional embodiment, the display screen structure further includes: a lens structure 3, and one lens structure 3 is correspondingly provided for at least one of the light-transmitting regions 12.
[0072] In this embodiment, as Figure 4As shown, a lens structure 3 can be correspondingly arranged at the position of the light-transmitting area 12. The lens structure 3 is a convex lens structure and can achieve the function of condensing light. As Figure 5 shown, ambient light at different angles is incident on the surface of the lens structure 3, and the lens structure 3 converges the light at different angles so that it is incident on the photosensitive element 2, thereby enabling ambient light at a larger incident angle to reach the photosensitive element below the display panel through the light-transmitting area, thereby reducing the optical signal difference of ambient light under different incident angles.
[0073] In one embodiment, as Figure 4 shown, the display panel 1 includes: a flat layer 4 covering the surface of the lens structure 3, and the light-incident surface of the lens structure 3 is located on the flat layer 4; the refractive index of the lens structure 3 is greater than the refractive index of the flat layer 4.
[0074] The flat layer 4 can be a color filter overcoating (CFOC) on the outermost layer of the display panel 1, which is used to protect the color film layer of the pixel unit 11 and can flatten the surface of the display panel 1. The lens structure 3 can be a material with a high refractive index, and its refractive index is greater than that of the flat layer 4, which can ensure that ambient light at more angles is incident on the photosensitive element 2. Even if the angle between the electronic device and the ambient light source changes, it will not cause a large difference in the amount of optical signal.
[0075] Among them, the lens structure 3 can be arranged on the surface of the light-transmitting area 12, and a transparent substance is filled in the light-transmitting area 12, or the lens structure 3 can be provided with an extension part, and the extension part is filled in the light-transmitting area 12. For example: the lens structure 3 includes: a convex lens 31 and an extension part 32. The convex lens 31 includes a light-incident surface and a light-emitting surface, the light-emitting surface is located on the surface of the light-transmitting area 12, the extension part 32 is connected to the light-emitting surface, and the extension part 32 is filled in the through hole where the light-transmitting area 12 is located.
[0076] As Figure 4 and Figure 5 shown, the convex lens 31 and the extension part 32 of the lens structure 3 are an integral structure. The convex lens 31 is located on the surface of the through hole where the light-transmitting area 12 is located and is within the flat layer 4; the extension part 32 extends into the through hole where the light-transmitting area 12 is located. In this way, the through hole where the light-transmitting area 12 is located does not need to be filled with an additional transparent substance. After the display panel 1 is drilled, the lens structure 3 is installed, and the flat layer 4 is further encapsulated, then the assembly of the display panel can be realized.
[0077] As an alternative embodiment, the light-transmitting area 12 is a polygonal light-transmitting area, or the light-transmitting area 12 is a non-circular light-transmitting area.
[0078] In an embodiment of the present application, the shape of the light-transmitting area 12 of the display panel may be non-circular, such as Figure 6 the rectangle shown, Figure 7 the cross shown, Figure 8 the rhombus shown, Figure 9 the star shown, Figure 10 the triangle shown, Figure 11 the trapezoid shown, etc., which will not be listed one by one here. For the traditional circular light-transmitting area, under the same ambient brightness, when the relative angle between the electronic device and the ambient light source changes, that is, when the incident angle of the ambient light changes, the true transmittance of the circular light-transmitting area will have a large difference, that is, the amount of light signals reaching the photosensitive element will have a large difference, which will cause the photosensitive element to make a wrong judgment, thereby wrongly adjusting the brightness and color temperature, affecting the user experience. In the present application, the light-transmitting area 12 is set to be non-circular or polygonal. Since the light-transmitting areas 12 are regularly arranged in the target area and / or the setting angle of the light-transmitting area 12 relative to the center line of the display panel 1 changes according to a preset angle value in the target area, the light-transmitting areas 12 in the target area can have different arrangement directions. In this way, when the angle between the electronic device and the ambient light source changes, light can enter the photosensitive element 2 through the light-transmitting areas 12 arranged at different angles, which can avoid the reduction of the amount of light signals received by the photosensitive element 2, so as to ensure the accurate judgment of the ambient light by the photosensitive element 2, and then accurately adjust the screen brightness and color temperature.
[0079] In an embodiment, the display panel 1 further includes: a thin film transistor 5, and the anode of the thin film transistor 5 is connected to the light-emitting device 111 of the pixel unit 11. As Figure 2 shown, a thin film transistor (TFT) can provide a driving circuit for the pixel unit 11 to make the light-emitting device emit light.
[0080] Optionally, the photosensitive element 2 is an infrared sensor and / or a color temperature sensor. The photosensitive element 2 receives the light entering through the light-transmitting area 12, and adjusts the brightness and color temperature of the display panel in different environments by processing the light signals, so that the display is clearer and the eyes are more comfortable when consumers use the electronic device.
[0081] The use of these two types of sensors requires the screen to have good light transmittance in the area corresponding to the sensors. Therefore, a light-transmitting area is designed in the first area corresponding to the display panel. In addition, to ensure that the sensors have high brightness and color temperature adjustment accuracy, when ambient light at different angles irradiates the screen, the smaller the change in the light flux reaching the surface of the sensors through the light-transmitting area on the display panel, the better. In the embodiment of the present application, by setting the shape of the light-transmitting area 12 in the first area to a preset shape (such as a polygon), and / or setting the angle between the light-transmitting area 12 in the first area and the center line of the display panel 1 to a preset angle, and a lens structure can be provided in the light-transmitting area 12. In this way, even if the relative angle between the electronic device and the ambient light source changes, it can ensure that enough light can pass through the light-transmitting area to reach the sensors, thereby ensuring the accuracy of the display panel brightness and color temperature adjustment.
[0082] In the embodiment of the present application, the display panel 1 may have a multi-layer structure, for example Figure 2 As shown, it includes a CFOC planarization layer 4, a black matrix layer (Black Matrix, BM) 6 arranged in sequence from top to bottom. The black matrix layer 6 is the black matrix layer of the color film, which is used to define the positions of the red, green, and blue color films or define the positions of the light-transmitting areas, prevent the mixing of the red, green, and blue color films, and can determine the visual effect of the integrated black of the display panel. An overcoating layer (Over Coating, OC) 7, which is an organic film layer, can protect the underlying touch panel (Touch Panel, TP) circuit and provide a flat base layer for the upper color film layer; a TP layer 8, which is used to provide the screen touch circuit; a thin film encapsulation (Thin Film Encapsulation, TFE) layer 9, which can protect the organic light-emitting material and block water and oxygen; a pixel layer 10, which can also be a black pixel define layer (Black Pixel Define Layer, BPDL), can define the pixel positions, define the positions of the light-transmitting areas, and at the same time has the functions of preventing light crosstalk and optimizing the integrated black visual effect; a thin film transistor 5 is located below the pixel layer 10 and provides a driving circuit for the light-emitting device 111 of the pixel layer 10. The display panel further includes a substrate (Substrate) 101, which can support the display panel and the driving circuit. The photosensitive element 2 is arranged below the substrate 101 and is spaced from the substrate 101.
[0083] The pixel unit 11 includes a light-emitting device 111. The light-emitting device 111 is located in the pixel layer 10 and is connected to the anode of the thin-film transistor 5. The pixel unit 11 further includes a color filter film, which is located in the black matrix layer 6. Pixel units of different colors correspond to color filter films of different colors. For example, the display panel 1 includes red pixel units, which have red color filter films. The light-emitting devices of the red pixel units emit red light and emit it from the red color filter films; the display panel 1 further includes green pixel units, which have green color filter films. The light-emitting devices of the green pixel units emit green light and emit it from the green color filter films; the display panel 1 further includes blue pixel units, which have blue color filter films. The light-emitting devices of the blue pixel units emit blue light and emit it from the blue color filter films. Figures 2 to 4 Use different filling patterns to identify pixel units 11 of different colors. For example, the pixel unit on the left is a red pixel unit, the pixel unit in the middle is a blue pixel unit, and the pixel unit on the right is a green pixel unit.
[0084] The following takes light-transmitting regions of different shapes as an example to illustrate the display screen structure of the present application.
[0085] In an alternative embodiment, the light-transmitting region 12 is set to be rectangular. Assuming that the cross-section of the rectangular light-transmitting region has the same area as the circular light-transmitting region, as Figure 12 shown, the diameter of the left circular light-transmitting region is about 6 um ( Figure 12 the A dimension in), and the width of the right rectangular light-transmitting region is greater than the width of the left circular light-transmitting region. The distance from the black matrix layer 6 to the pixel layer 10 is about 20 um ( Figure 12 the B dimension in), and the incident angle α is calculated to be about 16.7°. The long side of the rectangular light-transmitting region is 12 um ( Figure 11 the A” dimension in), and the distance from the black matrix layer 6 to the pixel layer 10 remains unchanged ( Figure 11 B” = B = 20 um in), and the incident angle β is calculated to be about 30.9°. In this way, the incident angle increases by 85%, and the improvement is obvious.
[0086] In a sub-region within the first region, assuming that the angles of multiple light-transmitting regions 12 with respect to the center line of the display panel 1 are preset angles, the included angle between the light-transmitting region 12 and the vertical center line of the display panel 1 rotates by 45 degrees in sequence. It can also be understood that the light-transmitting regions 12 are arranged periodically in a clockwise rotation of 45 degrees from left to right or from top to bottom in sequence. The case where the lens structure 3 is not provided in the light-transmitting region 12 is as Figure 1 shown, and the case where the lens structure 3 is provided in the light-transmitting region 12 is as Figure 6 shown.
[0087] This arrangement of the light-transmitting regions can ensure that when ambient light is incident on the screen from different directions, the difference in the amount of light signals reaching the under-screen sensor is small, asFigure 13 As shown, for the light-transmitting regions periodically arranged at different angles on the right side, the ambient light transmittance in the C direction and the D direction is significantly more than that of the uniformly arranged light-transmitting regions on the left side in the C direction and the D direction. The light-transmitting regions of this embodiment are periodically arranged at a preset angle, which can ensure that when the relative angle between the electronic device and the ambient light source changes, the difference in ambient light transmittance is small, improving the accuracy of the sensor in controlling brightness and color temperature, and solving the problem that the sensor in the OLED product without a polarizer inaccurately adjusts the screen brightness and color temperature. The range of the rotation angle of the above periodic arrangement is only an example, and it can also be other rotation angles within the range of -180 to 180 degrees. It can also be understood that: the difference in the setting angle of the above light-transmitting region 12 relative to the center line of the display panel is any angle from 1 degree to 180 degrees.
[0088] As Figure 6 shown, a lens structure 3 can also be provided in the light-transmitting region. Since a convex lens has a light-gathering effect, it can further increase the incident angle of the ambient light reaching the photosensitive element. Usually, the lens effect can increase the incident angle of the ambient light by more than 10%. In this way, the ambient light with a larger incident angle can pass through the light-transmitting region 12 to reach the sensor under the screen, thereby reducing the difference in the light signal amount of the ambient light under different incident angles. Among them, the lens structure 3 is a high refractive index OC, and the refractive index is greater than that of the flat layer 4. The schematic diagram of the light-gathering of the convex lens structure is as Figure 5 shown, the ambient light at a larger angle can pass through the light-transmitting hole to reach the sensor under the screen, which can solve the problem that the sensor in the OLED product without a polarizer inaccurately adjusts the screen brightness and color temperature.
[0089] In another alternative embodiment, the light-transmitting region 12 is cross-shaped, as Figure 7 shown. Assuming that the angle of the light-transmitting region 12 in the first region relative to the center line of the display panel 1 is a preset angle, the included angle between the light-transmitting region 12 and the vertical center line of the display panel 1 rotates in sequence at 22.5 degrees. It can also be understood that the light-transmitting region 12 is arranged in a periodic arrangement that rotates clockwise at 22.5 degrees in sequence from left to right or from top to bottom. As Figure 7 shown is a schematic diagram of the light-transmitting region 12 provided with the lens structure 3. From Figure 7 it can be seen that due to the structural characteristics of the cross shape, the setting angles of the light-transmitting regions 12 at different positions are different. In this way, when the relative angle between the electronic device and the ambient light source changes, the light in different directions can also enter the photosensitive element from the light-transmitting region. Setting a lens structure in the light-transmitting region can gather the light with a larger incident angle, so that more light enters the photosensitive element, ensuring that the photosensitive element can accurately judge the ambient light situation, and thus accurately adjusting the screen brightness and color temperature.
[0090] In another alternative embodiment, the light-transmitting region 12 is diamond-shaped, asFigure 8 As shown, it is assumed that the angle of the light-transmitting region 12 in the first region with respect to the center line of the display panel 1 is a preset angle, and the included angle between the light-transmitting region 12 and the vertical center line of the display panel 1 rotates successively by 45 degrees. It can also be understood that the light-transmitting regions 12 are arranged periodically in a clockwise rotation of 45 degrees from left to right or from top to bottom in sequence.
[0091] As Figure 8 shown is a schematic diagram of the lens structure 3 provided in the light-transmitting region 12. From Figure 8 this, it can be seen that the set angles of the light-transmitting regions 12 at different positions are different. In this way, when the relative angle between the electronic device and the ambient light source changes, light rays in different directions can also enter the photosensitive element from the light-transmitting regions. By providing a lens structure in the light-transmitting region, light rays with a larger incident angle can be converged, so that more light rays enter the photosensitive element, ensuring that the photosensitive element can accurately judge the ambient light condition, and thus accurately adjusting the screen brightness and color temperature.
[0092] In another alternative embodiment, the light-transmitting region 12 is star-shaped. As Figure 9 shown, it is assumed that the angle of the light-transmitting region 12 in the first region with respect to the center line of the display panel 1 is a preset angle, and the included angle between the light-transmitting region 12 and the vertical center line of the display panel 1 rotates successively by 22.5 degrees. It can also be understood that the light-transmitting regions 12 are arranged periodically in a clockwise rotation of 22.5 degrees from left to right or from top to bottom in sequence.
[0093] As Figure 9 shown is a schematic diagram of the lens structure 3 provided in the light-transmitting region 12. From Figure 9 this, it can be seen that due to the structural characteristics of the star shape, the set angles of the light-transmitting regions 12 at different positions are different. In this way, when the relative angle between the electronic device and the ambient light source changes, light rays in different directions can also enter the photosensitive element from the light-transmitting regions. By providing a lens structure in the light-transmitting region, light rays with a larger incident angle can be converged, so that more light rays enter the photosensitive element, ensuring that the photosensitive element can accurately judge the ambient light condition, and thus accurately adjusting the screen brightness and color temperature.
[0094] In another alternative embodiment, the light-transmitting region 12 is triangular. As Figure 10 shown, it is assumed that the angle of the light-transmitting region 12 in the first region with respect to the center line of the display panel 1 is a preset angle, and the included angle between the light-transmitting region 12 and the vertical center line of the display panel 1 rotates successively by 45 degrees. It can also be understood that the light-transmitting regions 12 are arranged periodically in a clockwise rotation of 45 degrees from left to right or from top to bottom in sequence. As Figure 10 shown is a schematic diagram of the lens structure 3 provided in the light-transmitting region 12.
[0095] In another alternative embodiment, the light-transmitting region 12 is trapezoidal. As Figure 11 shown, assuming that the angle of the light-transmitting region 12 in the first region relative to the center line of the display panel 1 is a preset angle, the included angle between the light-transmitting region 12 and the center line in the vertical direction of the display panel 1 rotates by 45 degrees in sequence. It can also be understood that the light-transmitting regions 12 are arranged periodically in a clockwise rotation of 45 degrees from left to right or from top to bottom. As Figure 11 shown is a schematic diagram of the lens structure 3 provided in the light-transmitting region 12.
[0096] In another alternative embodiment, the light-transmitting region 12 is circular. As Figure 14 shown, by providing the lens structure 3 in the light-transmitting region 12, light rays with a larger incident angle can be converged, so that more light rays are incident on the photosensitive element, ensuring that the photosensitive element can accurately judge the ambient light condition, and thus accurately adjusting the screen brightness and color temperature.
[0097] In this embodiment, the original shape of the light-transmitting region is changed, the light-transmitting regions are arranged periodically at a certain rotation angle, and a convex lens design is added. The shape of the light-transmitting region can be rectangular, rhombic, triangular, cross-shaped, star-shaped or other irregular shapes, as long as it is beneficial to increasing the incident angle of the ambient light reaching the photosensitive element. The arrangement of the light-transmitting regions can be that multiple light-transmitting regions are arranged periodically or locally periodically at a certain rotation angle, and the rotation angle can be from -180° to 180°, which can effectively reduce the difference in the amount of light signals reaching the photosensitive element at different incident angles of the ambient light.
[0098] In the embodiments of the present application, the shape and arrangement of the light-transmitting regions can be realized through the shape design of the black matrix layer 6 and the pixel layer 10. The lens structure can be an OC with a high refractive index, and its refractive index is greater than that of the flat layer 4.
[0099] This embodiment can increase the incident angle of the ambient light passing through the light-transmitting region to reach the under-screen sensor, reduce the difference in the amount of light signals reaching the sensor under different incident angles and different incident directions of the ambient light, thereby improving the accuracy of the under-screen sensor in controlling the screen brightness and color temperature, and thus enhancing the user experience and improving the problems in the application of current products (such as OLED Polless products).
[0100] In the embodiments of the present application, one or more light-transmitting regions are provided in the first region of the display panel. The interface of the light-transmitting region has a preset shape, and / or the light-transmitting region forms a preset angle relative to the center line of the display panel, which can ensure that after the relative angle between the electronic device and the ambient light source changes, there are still more light rays passing through the light-transmitting region and incident on the photosensitive element, ensuring the accurate judgment of the ambient light by the photosensitive element, and thus accurately adjusting the screen brightness and color temperature.
