[0045] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0047] It can be understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first preset condition may be referred to as a second preset condition, and similarly, a second preset condition may be referred to as a first preset condition. Both the first preset condition and the second preset condition are preset conditions, but they are not the same preset condition. In the description of the embodiments of this application, "a plurality of" means two or more unless otherwise specifically defined.

[0048] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0049] With the development of electronic technology, electronic devices such as mobile phones and tablet computers are becoming increasingly important in people's work and life, and face recognition functions are set on more and more electronic devices. The implementation process of the face recognition (Face ID) function is as follows: First, devices for implementing the face recognition function are set under the screen of the electronic device. Among them, as Figure 1 shown, Figure 1 is a schematic structural diagram of the area where the devices for implementing the face recognition function are located in an embodiment. The devices for implementing the face recognition function may include, but are not limited to, an ambient light sensor, a distance sensor, an infrared lens, a flood illumination sensor, and a dot projector, etc.; in addition, camera devices such as a speaker, a microphone, and a camera may also be set in the area under the screen where the devices for implementing the face recognition function are located.

[0050] Secondly, when the ambient light sensor detects good lighting conditions and the proximity sensor detects the presence of a detected object (such as a human face, etc.) within a certain range, the dot matrix projector and the infrared lens can be turned on. Thus, the dot matrix projector can project hundreds of thousands of infrared point light sources invisible to the naked eye outside the screen. When the infrared point light sources are projected onto the detected object, the detected object can reflect the infrared point light sources to the infrared lens, enabling the infrared lens to capture an infrared photo through the infrared point light sources and generate a three-dimensional (3D) model corresponding to the detected object based on the infrared photo. Subsequently, facial recognition can be performed based on the three-dimensional (3D) model corresponding to the detected object to obtain the facial recognition result of the detected object. In addition, when the ambient light sensor detects poor lighting conditions (such as a dark environment at night, etc.), hundreds of thousands of infrared point light sources invisible to the naked eye can be projected outside the screen through the floodlight sensing element, thereby completing facial recognition.

[0051] Among them, as Figure 2 shown, Figure 2 FIG. [FIGURE NUMBER] is a schematic structural diagram of a screen capable of content display in a conventional method in an embodiment. From a longitudinal cross-section, the screen capable of content display in the electronic device includes a stacked structure 2, and the stacked structure 2 includes a pixel driving circuit layer 21, a light-emitting layer 22, a polarizer 23, and glass 24. Among them, the pixel driving circuit layer 21 includes thin film field effect transistors (TFTs), and the pixel driving circuit layer 21 is used to control whether the light-emitting layer 22 emits light. The light-emitting layer 22 can be an electro-luminescent (EL) sheet. As Figure 3 shown, Figure 3 FIG. [FIGURE NUMBER] is a schematic diagram of the pixel arrangement of the light-emitting layer in a conventional method in an embodiment. The light-emitting layer 22 includes R, G, and B pixels, and the light-emitting layer 22 is used to display content or a picture. The light transmittance of the light-emitting layer 22 is generally only about 50%. The polarizer 23 is used to reduce the brightness of the screen in the off-screen state to enhance the contrast of the screen. The glass 24 is used to protect the screen. For the screen capable of displaying content, the light transmittance of the screen capable of displaying content is generally 2% - 3%, while the light transmittance required for facial recognition is generally 5%. Therefore, the light transmittance of the screen capable of displaying content cannot meet the light transmittance requirements for facial recognition. Furthermore, through the screen capable of displaying content, the dot matrix projector cannot pass through the screen and project hundreds of thousands of infrared point light sources invisible to the naked eye outside the screen. Therefore, facial recognition cannot be performed through the screen capable of displaying content. In contrast, the light transmittance of the screen that does not display content is generally 20%. Therefore, the light transmittance of the screen that does not display content can meet the light transmittance requirements for facial recognition. Furthermore, facial recognition can be performed through the screen that does not display content.

[0052] Based on this, in order to ensure that the face recognition function of the device can work properly, it is necessary to ensure that the screen corresponding to the location of the device has a high light transmittance. Since electronic devices can include but are not limited to mobile phones, tablets, etc., and in order to ensure that the screen corresponding to the location of the device has a high light transmittance, therefore, in traditional methods, for mobile phones, such as Figure 4 as shown, Figure 4 is a schematic structural diagram of the area where the device is located in a traditional method for a mobile phone in an embodiment. The screen where the device for implementing the face recognition function is located (i.e., Figure 4 the gray rectangular frame area in) can be perforated. At this time, there is no display device in the screen corresponding to the location of the device; for tablets, such as Figure 5 as shown, Figure 5 is a schematic structural diagram of the area where the device is located in a traditional method for a tablet in an embodiment. The border can be enlarged, and the device for implementing the face recognition function can be set at the location of the border (i.e., Figure 5 the gray rectangular frame area in). At this time, content cannot be displayed at the location of the border, and the proportion of the screen display area in all areas of the screen will be reduced. Therefore, in order to ensure that the screen corresponding to the location of the device has a high light transmittance, in traditional methods, content generally cannot be displayed on the screen corresponding to the location of the device.

[0053] Based on this, in an embodiment, the present application provides a light-emitting layer, and the light-emitting layer includes a first light-emitting area and a second light-emitting area; the first light-emitting area includes blank pixels and color pixels, and the second light-emitting area includes color pixels;

[0054] The first light-emitting area includes a plurality of first RGB pixel array combinations arranged in an array. Each first RGB pixel array combination includes a plurality of different color pixel arrays; each color pixel array includes a plurality of first pixel units arranged diagonally. The first pixel unit includes a first type of pixel unit, a second type of pixel unit, and a blank pixel unit; the blank pixel unit includes blank pixels.

[0055] The second light-emitting area includes a plurality of second RGB pixel arrays arranged in an array. Each second RGB pixel array includes a plurality of second pixel units arranged diagonally. Each second pixel unit includes a first type of pixel unit and a second type of pixel unit;

[0056] The first light-emitting area and the second light-emitting area are used for content display through the color pixels in the first light-emitting area and the color pixels in the second light-emitting area.

[0057] Among them, the light-emitting layer can be an electro-luminescent (EL) sheet, and the light-emitting layer is used to display content or images. The light-emitting layer includes a first light-emitting region and a second light-emitting region, and the first light-emitting region and the second light-emitting region are regions with different light transmittances in the light-emitting layer. Optionally, the light-emitting layer can only include the first light-emitting region and the second light-emitting region; or, the light-emitting layer can not only include the first light-emitting region and the second light-emitting region, but also include other regions with different light transmittances from the first light-emitting region and the second light-emitting region. The blank pixel is a W pixel, and the color pixel can be an R pixel, a G pixel, or a B pixel. Among them, the shape of the color pixel in the embodiments of the present application can include, but is not limited to, shapes such as circles, rectangles, rhombuses, squares, etc., that is, the embodiments of the present application do not limit the shape of the color pixel.

[0058] Exemplarily, as Figure 6 shown, Figure 6 FIG. 6 is a schematic structural diagram of a light-emitting layer in an embodiment. The light-emitting layer 600 includes a first light-emitting region 620 and a second light-emitting region 640. The first light-emitting region 620 includes blank pixels and color pixels; the second light-emitting region 640 includes color pixels, that is, the second light-emitting region 640 does not include blank pixels. Of course, the arrangement of each pixel in the first light-emitting region 620 and the second light-emitting region 640 is not limited in this embodiment. Since the first light-emitting region 620 includes blank pixels while the second light-emitting region 640 does not include blank pixels, it can be determined that the light transmittance of the first light-emitting region 620 is greater than that of the second light-emitting region 640. And since both the first light-emitting region 620 and the second light-emitting region 640 include color pixels, the first light-emitting region 620 and the second light-emitting region 640 can be used to display content.

[0059] Among them, the first RGB pixel array combination is an array combination composed of multiple different color pixel arrays, and the first RGB pixel array combination is periodically arrayed in the first light-emitting region. The color pixel array is a pixel array composed of a plurality of first pixel units arranged diagonally, and each color pixel array includes blank pixels and color pixels. The first pixel unit includes a first type of pixel unit, a second type of pixel unit, and a blank pixel unit. Both the first type of pixel unit and the second type of pixel unit include color pixels, and the blank pixel unit includes blank pixels. The second RGB pixel array is a pixel array composed of a plurality of second pixel units arranged diagonally, and the second RGB pixel array combination is periodically arrayed in the second light-emitting region. Each second pixel unit includes a first type of pixel unit and a second type of pixel unit, that is, each second pixel unit includes color pixels.

[0060] Exemplarily, the first light-emitting region includes a plurality of first RGB pixel array combinations arranged in an array, each first RGB pixel array combination includes a plurality of different color pixel arrays, each color pixel array includes a plurality of first pixel units arranged diagonally, and the first pixel unit includes a first type of pixel unit, a second type of pixel unit, and a blank pixel unit. That is, it can be understood that the first light-emitting region includes a plurality of first type of pixel units, second type of pixel units, and blank pixel units arranged diagonally, and the plurality of first type of pixel units, second type of pixel units, and blank pixel units arranged diagonally are periodically arranged in the first light-emitting region.

[0061] The second light-emitting region includes a plurality of second RGB pixel arrays arranged in an array, each second RGB pixel array includes a plurality of second pixel units arranged diagonally, and each second pixel unit includes a first type of pixel unit and a second type of pixel unit. That is, it can be understood that the second light-emitting region includes a plurality of first type of pixel units and second type of pixel units arranged diagonally, and the plurality of first type of pixel units and second type of pixel units arranged diagonally are periodically arranged in the second light-emitting region.

[0062] In the above-mentioned light-emitting layer, since the light-emitting layer in the embodiment of the present application includes a first light-emitting region and a second light-emitting region, wherein the first light-emitting region includes a plurality of first RGB pixel array combinations arranged in an array, each first RGB pixel array combination includes a plurality of different color pixel arrays; each color pixel array includes a plurality of first pixel units arranged diagonally, and the first pixel unit includes a first type of pixel unit, a second type of pixel unit, and a blank pixel unit. Therefore, each color pixel array in the first light-emitting region includes blank pixels and color pixels. And since the second light-emitting region includes a plurality of second RGB pixel arrays arranged in an array, each second RGB pixel array includes a plurality of second pixel units arranged diagonally, and each second pixel unit includes a first type of pixel unit and a second type of pixel unit. Therefore, each second pixel unit in the second light-emitting region includes color pixels, that is, the second light-emitting region does not include blank pixels.

[0063] Since each color pixel array in the first light-emitting region includes blank pixels and color pixels, and each second pixel unit in the second light-emitting region includes color pixels, while the second light-emitting region does not include blank pixels. Therefore, the light transmittance of the first light-emitting region is greater than that of the second light-emitting region. At the same time, since both the first light-emitting region and the second light-emitting region include color pixels. Therefore, content can be displayed through the color pixels of the first light-emitting region and the color pixels of the second light-emitting region. In summary, the light-emitting layer in the present application not only has a high light transmittance, but also can display content through the light-emitting layer of the present application.

[0064] In the above embodiments, the first type of pixel units and the second type of pixel units are described. In an exemplary embodiment, the first type of pixel units include B pixels and G pixels arranged diagonally, and the second type of pixel units include R pixels and G pixels arranged diagonally; in the second light-emitting region, the first type of pixel units are arranged diagonally, and the second type of pixel units are arranged diagonally in the other direction;

[0065] In the first light-emitting region, the first type of pixel units, the second type of pixel units, and the blank pixel units in each color pixel array are arranged according to a preset array format.

[0066] Exemplarily, as Figure 7 shown, Figure 7 FIG. is a schematic structural diagram of an embodiment including the first type of pixel units and the second type of pixel units. The first type of pixel units 720 include B pixels and G pixels arranged diagonally, and the second type of pixel units 740 include R pixels and G pixels arranged diagonally. In the first light-emitting region, the first type of pixel units 720, the second type of pixel units 740, and the blank pixel units in each color pixel array are arranged according to a preset array format. Among them, the preset array format can be specifically set according to the actual pixels. Of course, this embodiment does not limit the preset array format. Exemplarily, as Figure 8 shown, Figure 8 FIG. is a schematic structural diagram of an embodiment including a second RGB pixel array. In the second light-emitting region, the first type of pixel units 720 in each second RGB pixel array 800 are arranged diagonally, and the second type of pixel units 740 are arranged diagonally in the other direction.

[0067] In this embodiment, since the first type of pixel units include B pixels and G pixels arranged diagonally, and the second type of pixel units include R pixels and G pixels arranged diagonally, in the second light-emitting region, the first type of pixel units are arranged diagonally, and the second type of pixel units are arranged diagonally in the other direction. Therefore, it can be ensured that the second light-emitting region includes color pixels and does not include blank pixels. In the first light-emitting region, the first type of pixel units, the second type of pixel units, and the blank pixel units in each color pixel array are arranged according to a preset array format. Therefore, it can be ensured that the first light-emitting region includes blank pixels and color pixels. Thus, it can be ensured that the light transmittance of the first light-emitting region is greater than that of the second light-emitting region. At the same time, since both the first light-emitting region and the second light-emitting region include color pixels, the content can be displayed through the color pixels in the first light-emitting region and the color pixels in the second light-emitting region.

[0068] In the above embodiments, it is described that in the first light-emitting region, the first type of pixel units, the second type of pixel units, and the blank pixel units in each color pixel array are arranged in a preset array format. In an exemplary embodiment, the array size of the first RGB pixel array combination in the first direction is related to the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction.

[0069] In an exemplary embodiment, the array size of the first RGB pixel array combination in the second direction is the same as the array size of the second RGB pixel array in the second direction; the first direction and the second direction are perpendicular to each other.

[0070] Exemplarily, the first light-emitting region includes a plurality of identical first RGB pixel array combinations arranged in an array. For each first RGB pixel array combination, the array size of the first RGB pixel array combination in the first direction is related to the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction. Optionally, the array size of the first RGB pixel array combination in the first direction may be equal to the product of the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction and the array size of each color pixel array; or, the array size of the first RGB pixel array combination in the first direction may also be equal to the product of a preset multiple of the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction and the array size of each color pixel array. For each first RGB pixel array combination, the array size of the first RGB pixel array combination in the second direction is the same as the array size of the second RGB pixel array in the second direction, that is, it can be understood that the array size of the first RGB pixel array combination in the second direction is equal to the array size of the second RGB pixel array in the second direction.

[0071] Among them, the first RGB pixel array combination is a rectangular array combination composed of a plurality of different color pixel arrays. The rectangular array combination includes a first side and a second side. The length of the first side is greater than the length of the second side. The first side corresponds to the first direction, the second side corresponds to the second direction, the first side and the second side are perpendicular to each other, and the first direction and the second direction are perpendicular to each other. The array size of the first RGB pixel array combination in the first direction refers to the array size included in the first side of the first RGB pixel array combination. The cycle period of the blank pixel units in the first RGB pixel array combination in the first direction refers to the number of times the blank pixel units appear cyclically on the first side of the first RGB pixel array combination. The preset multiple can be specifically set according to the actual pixels. Of course, this embodiment does not limit the preset array format. The array size of the first RGB pixel array combination in the second direction refers to the array size included in the second side of the first RGB pixel array combination. The array size of the second RGB pixel array in the second direction refers to the array size included in the second side of the second RGB pixel array combination.

[0072] In this embodiment, the array size of the first RGB pixel array combination in the first direction is related to the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction; the array size of the first RGB pixel array combination in the second direction is the same as the array size of the second RGB pixel array in the second direction; the first direction and the second direction are perpendicular to each other. Through the above array arrangement, it can be ensured that the first RGB pixel array combination not only includes blank pixel units, but also includes color pixels capable of normally displaying content. In this way, it can be ensured that the screen content can be normally displayed through the first RGB pixel array combination.

[0073] In the above embodiment, it is described that the array size of the first RGB pixel array combination in the first direction is related to the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction. In an exemplary embodiment, the first RGB pixel array combination includes a preset number of different color pixel arrays; the preset number is equal to the cycle period.

[0074] Exemplarily, the first RGB pixel array combination includes a preset number of different color pixel arrays, where the preset number is equal to the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction. That is, it can be understood that the array size of the first RGB pixel array combination in the first direction can be equal to the product of the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction and the array size of each color pixel array. Exemplarily, when the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction is 3, each first RGB pixel array combination includes 3 different color pixel arrays; when the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction is 4, each first RGB pixel array combination includes 4 different color pixel arrays; when the cycle period of the blank pixel units in the first RGB pixel array combination in the first direction is 5, each first RGB pixel array combination includes 5 different color pixel arrays.

[0075] In this embodiment, the first RGB pixel array combination includes a preset number of different color pixel arrays; the preset number is equal to the cycle period. In this way, multiple arrangement methods of the first RGB pixel array combination can be determined, and this arrangement method can ensure that the first RGB pixel array combination not only includes blank pixel units, but also includes color pixels capable of normally displaying content.

[0076] In the above embodiments, it is described that the first RGB pixel array combination includes a preset number of different color pixel arrays. In an exemplary embodiment, if the cycle period is 3 pixel units, the first RGB pixel array combination includes 3 different color pixel arrays; the 3 different color pixel arrays include a first color pixel array, a second color pixel array, and a third color pixel array;

Each blank pixel unit is arranged diagonally, and each second type of pixel unit is arranged in another diagonal;

[0079] The third color pixel array includes a fifth column and a sixth column. The fifth column includes a first type of pixel unit and a second type of pixel unit arranged in sequence, and the sixth column includes a blank pixel unit and a first type of pixel unit arranged in sequence. Each first type of pixel unit is arranged diagonally, and the blank pixel unit and the second type of pixel unit are arranged in another diagonal.

[0080] Exemplarily, if the cycle period of the blank pixel unit in the first RGB pixel array combination in the first direction is 3 pixel units, the first RGB pixel array combination includes 3 different color pixel arrays. As Figure 9 shown, Figure 9 FIG. 16 is a schematic structural diagram of a first RGB pixel array combination in an embodiment. Among them, the first RGB pixel array combination 900 includes 3 different color pixel arrays, and the 3 different color pixel arrays include a first color pixel array 920, a second color pixel array 940, and a third color pixel array 960.

[0081] Combined with Figure 9As shown in the figure, the first color pixel array 920 includes a first column 901 and a second column 902. The first column 901 includes first-class pixel units 720 and blank pixel units 922 arranged in sequence. The second column 902 includes second-class pixel units 740 and first-class pixel units 720 arranged in sequence. Among them, each blank pixel unit 922 includes four blank pixels. The first-class pixel units 720 are arranged diagonally, and the second-class pixel units 740 and the blank pixel units 922 are arranged in another diagonal. The second color pixel array 940 includes a third column 903 and a fourth column 904. The third column 903 includes blank pixel units 922 and second-class pixel units 740 arranged in sequence. The fourth column 904 includes second-class pixel units 740 and blank pixel units 922 arranged in sequence. Each blank pixel unit 922 is arranged diagonally, and each second-class pixel unit 740 is arranged in another diagonal. The third color pixel array 960 includes a fifth column 905 and a sixth column 906. The fifth column 905 includes first-class pixel units 720 and second-class pixel units 740 arranged in sequence. The sixth column 906 includes blank pixel units 922 and first-class pixel units 720 arranged in sequence. Each first-class pixel unit 720 is arranged diagonally, and the blank pixel units 922 and the second-class pixel units 740 are arranged in another diagonal.

[0082] In an exemplary embodiment, as Figure 10 shown, Figure 10 is a schematic structural diagram of a light-emitting layer including a first light-emitting region and a second light-emitting region in an embodiment. Among them, the light-emitting layer includes a first light-emitting region and a second light-emitting region. The first light-emitting region 900 is the region where the thick black rectangular frame is located. The second light-emitting region is all regions of the light-emitting layer except the first light-emitting region. The first light-emitting region includes 2 first RGB pixel array combinations arranged in an array. Each first RGB pixel array combination includes 3 different color pixel arrays, and the 3 different color pixel arrays include a first color pixel array, a second color pixel array, and a third color pixel array. The arrangement manners of the first color pixel array, the second color pixel array, and the third color pixel array can refer to Figure 9 the corresponding embodiment and will not be elaborated here. The second light-emitting region includes a plurality of second RGB pixel arrays arranged in an array. Each second RGB pixel array includes 2 first-class pixel units arranged diagonally and 2 second-class pixel units arranged in another diagonal. The arrangement manner of each second RGB pixel array can refer to Figure 8 the corresponding embodiment and will not be elaborated here.

[0083] That is to say, it can be understood that the pixel array in the first light-emitting area is the pixel array obtained by deleting the pixel array in the second light-emitting area. The specific deletion method is as follows: for the pixels in odd rows, taking 3 pixel units as a period, the pixel unit at the 3rd position is deleted to obtain a blank pixel unit at the 3rd position in each period; for the pixels in even rows, taking 3 pixel units as a period, the pixel unit at the 1st position is deleted to obtain a blank pixel unit at the 1st position in each period. It should be noted that in the embodiments of the present application, the pixels corresponding to the central position of the second light-emitting area cannot be deleted, otherwise the normal display of the content may be affected.

[0084] In this embodiment, if the cycle period is 3 pixel units, the first RGB pixel array combination includes 3 different color pixel arrays; the 3 different color pixel arrays include a first color pixel array, a second color pixel array, and a third color pixel array. Through the arrangement method of the color pixel arrays in this embodiment, not only can the light-transmitting rate of the light-emitting layer be ensured to be high, but also good content display can be ensured through the light-emitting layer, so as to achieve a balance between a high light-transmitting rate and good content display.

[0085] In one embodiment, the present application provides a screen assembly, including the light-emitting layer and the pixel driving circuit layer as described in the above embodiments; the pixel driving circuit layer is located below the light-emitting layer;

[0086] Through holes corresponding to the positions where the blank pixels are located are formed on the pixel driving circuit layer.

[0087] Exemplarily, as Figure 11 shown, Figure 11 is a schematic structural diagram of a screen assembly in an embodiment. In Figure 11 , from the longitudinal section view, the screen assembly 11 includes the light-emitting layer 112 and the pixel driving circuit layer 111 as described in the above embodiments. Among them, the structure of the light-emitting layer 112 can refer to the above embodiments and will not be elaborated here. The pixel driving circuit layer 21 includes thin film field effect transistors (TFTs), and the pixel driving circuit layer 21 is used to control whether the light-emitting layer 22 emits light. The pixel driving circuit layer 111 is located below the light-emitting layer 112, and through holes corresponding to the positions where the blank pixels are located are formed on the pixel driving circuit layer 111, which can reduce the number of color pixels in the light-emitting layer 112 and also reduce the structure of the pixel driving circuit layer 111. In addition, the screen assembly 11 may further include glass 114.

[0088] Exemplarily, as Figure 12 shown, Figure 12Schematic diagram of the effect of using a screen component for content display in an embodiment. Among them, the darker area corresponding to the time (19:30) represents the first light-emitting area, and the area around it that is brighter than the first light-emitting area represents the second light-emitting area. Based on Figure 12 It can be seen that content can be displayed on the first light-emitting area.

[0089] In the above screen component, there are a light-emitting layer and a pixel driving circuit layer; the pixel driving circuit layer is located below the light-emitting layer; through holes corresponding to the positions of blank pixels are opened on the pixel driving circuit layer. By redesigning and arranging the pixel arrangement of the light-emitting layer in the screen component and opening through holes corresponding to the positions of blank pixels on the pixel driving circuit layer, it is possible to reduce the number of color pixels in the light-emitting layer 112 while also reducing the structure of the pixel driving circuit layer 111. Thus, the light transmittance of the screen component can be improved, and further, the face recognition function can be realized through the displayable screen. Therefore, the embodiment of the present application can not only ensure that the screen component corresponding to the position of the device for realizing the face recognition function has a high light transmittance, but also ensure that good content display can be performed through the screen component corresponding to the position of the device.

[0090] In the above embodiment, it is described that the screen component includes a light-emitting layer and a pixel driving circuit layer. In an exemplary embodiment, the screen component further includes a polarizer; through holes corresponding to the first light-emitting area are opened on the polarizer.

[0091] Exemplarily, in combination with Figure 11 As shown, the screen component further includes a polarizer 113. In one alternative embodiment, as Figure 13 shown, Figure 13 Schematic diagram of the structure of a screen component including a polarizer with through holes in an embodiment. Among them, through holes corresponding to the first light-emitting area are opened on the polarizer 113, or alternatively, the area of the polarizer corresponding to the first light-emitting area can be cut off to ensure that the light transmittance of the polarizer is higher than 90%. The polarizer 113 (Polarizer) is used to reduce the brightness of the screen in the off-screen state to improve the contrast of the screen.

[0092] In this embodiment, the screen component further includes a polarizer; through holes corresponding to the first light-emitting area are opened on the polarizer. By opening through holes corresponding to the first light-emitting area on the polarizer, the light transmittance of the screen component can be further improved, and thus, the face recognition function can be realized through the displayable screen.

[0093] In the above embodiment, it is described that the screen component includes a light-emitting layer and a pixel driving circuit layer. In an exemplary embodiment, a shielding layer is provided at the interval position of the color pixels in the second light-emitting area.

[0094] Exemplarily, asFigure 14 As shown Figure 14 in the figure, it is a schematic structural diagram of a screen component with an occlusion layer provided in an embodiment. It is also possible to directly cancel or delete Figure 11 the polarizer 113 in [[ID=]], and set an occlusion layer 115 at the interval position of the color pixels in the second light-emitting area of the light-emitting layer 112, so that the occlusion layer 115 achieves the effect of a polarizer; and no occlusion layer 115 is provided at the interval position of the color pixels in the first light-emitting area of the light-emitting layer 112.

[0095] In this embodiment, an occlusion layer is provided at the interval position of the color pixels in the second light-emitting area. By directly canceling or deleting the polarizer and setting an occlusion layer at the interval position of the color pixels in the second light-emitting area, the light transmittance of the screen component can be further improved, and thus, the face recognition function can be realized through the displayable screen.

[0096] In one embodiment, the present application provides an electronic device, including a memory, a processor, and a screen component as described in the above embodiment.

[0097] Exemplarily, the electronic device 120 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, smart cars, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. As Figure 15 shown Figure 15 in the figure, it is a schematic structural diagram of an electronic device in an embodiment. In Figure 15 it, the electronic device includes a memory, a processor, and a screen component 15 as described in the above embodiment. The screen component 15 includes a normal display area 151 and a device area 152. The shape of the device area 152 is capsule-shaped, oval-shaped, or rectangular. Of course, the shape of the device area 152 is not limited in the embodiments of the present application. Devices for realizing the face recognition function, such as an infrared lens 1521, a floodlight sensor 1522, and a dot projector 1523, can be provided in the device area 152. Of course, the devices for realizing the face recognition function can include, but are not limited to, an ambient light sensor, a distance sensor, an infrared lens, a floodlight sensor, and a dot projector, etc.

[0098] As Figure 16 shown Figure 16Schematic diagram of the process for face recognition in an embodiment. When the ambient light sensor detects that the lighting condition is good and the distance sensor detects that there is a detected object (such as a human face, etc.) within a certain range, the dot matrix projector 1523 and the infrared lens 1521 can be turned on. Thus, the dot matrix projector 1523 can project hundreds of thousands of infrared point light sources invisible to the naked eye outside the screen. When the infrared point light sources are projected onto the detected object, the detected object can reflect the infrared point light sources to the infrared lens 1521, so that the infrared lens 1521 can take an infrared photo through the infrared point light sources and generate a three-dimensional (3D) model corresponding to the detected object according to the infrared photo. Then, face recognition can be performed based on the three-dimensional (3D) model corresponding to the detected object to obtain the face recognition result of the detected object. In addition, when the ambient light sensor detects that the lighting condition is poor (such as a dark environment at night, etc.), hundreds of thousands of infrared point light sources invisible to the naked eye can be projected outside the screen through the floodlight sensing element 1522, and then face recognition can be completed.

[0099] In the above electronic device, a memory, a processor, and a screen component as in the above embodiment are included. Therefore, by redesigning and arranging the pixel arrangement of the light-emitting layer in the screen component and opening through holes corresponding to the positions where the blank pixels are located on the pixel driving circuit layer, it is possible to reduce the number of color pixels in the light-emitting layer 112 while also reducing the structure of the pixel driving circuit layer 111. Thus, the light transmittance of the screen component can be improved, and then the face recognition function can be realized through the displayable screen. In addition, for the beneficial effects of the light-emitting layer, reference can be made to the above embodiment, and details are not described here.
