[0028] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the directional words such as "upper" and "lower" used generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0029] Combine the following Figures 1 to 7 The imaging display screen assembly and electronic device of the present application are described.

[0030] According to the embodiment of the first aspect of the present application, Figure 1 , Figure 2 and Figure 3 The imaging display screen assembly includes a display screen 1 and a spectral chip 2. The display screen 1 includes a first display area 11 and a second display area 12. The transmittance of the first display area 11 is greater than the transmittance of the second display area 12. The first display area 11 is provided with a plurality of luminous pixels 111 and a plurality of translucent pixels 112. The spectral chip 2 is arranged on the back of the display screen 1. The spectral chip 2 faces the first display area 11. The spectral chip 2 is suitable for receiving light transmitted through the translucent pixels 112 to obtain imaging data for display on the display screen 1.

[0031] According to the imaging display screen assembly of the present application, the display screen 1 is divided into a first display area 11 and a second display area 12, wherein the second display area 12 is mainly used for luminous imaging, and the first display area 11 includes luminous pixels 111 and light-transmitting pixels 112, that is, the first display area 11 can emit light, and external light can also be projected to the back of the display screen 1 through the light-transmitting pixels 112 of the first display area 11. The spectral chip 2 on the back of the display screen 1 is facing the first display area 11, and the light transmitted through the light-transmitting pixels 112 can accurately enter the spectral chip 2, so that the spectral chip 2 can accurately and completely receive the external light incident on the display screen 1. After receiving the light, the spectral chip 2 processes the light to obtain imaging data, so that the display screen 1 can display imaging according to the imaging data. In other words, the present application sets the spectral chip 2 on the back of the display screen 1, uses the spectral chip 2 for imaging, so that the display screen 1 has an imaging function, and uses the spectral chip 2 to replace the front camera, optimizes the structure of the display screen 1, and can achieve a true full screen, improving the aesthetics of the display screen 1. At the same time, since the first display area 11 includes both luminous pixels 111 and translucent pixels 112, while the spectral chip 2 receives external light through the translucent pixels 112, the luminous pixels 111 of the first display area 11 can emit light according to the imaging data, so that the display screen 1 can form an image (emit light) while shooting (sensing), which will not affect the user's use.

[0032] It is understandable that the spectrum chip 2 and the display screen 1 can be integrally formed, or they can be formed separately and then connected together.

[0033] In one embodiment of the present application, Figure 3 , the luminous pixels 111 and the translucent pixels 112 are staggered with each other, and the spectral chip 2 is directly opposite to the translucent pixels 112 .

[0034] It can be understood that the luminous pixels 111 and the light-transmitting pixels 112 of the first display area 11 are set to be staggered with each other, that is, the luminous position and the light-transmitting position at the first display area 11 are staggered with each other, thereby improving the distribution uniformity of the luminous pixels 111 and the light-transmitting pixels 112 at the first display area 11. When the first display area 11 is in the display mode, the non-luminous light-transmitting pixels 112 of the first display area 11 are separated by the luminous pixels 111, which can avoid the user observing that part of the first display area 11 is not luminous, so that the first display area 11 is no different from the second display area 12 in the eyes of the user, and the user can hardly notice that part of the pixels of the first display area 11 are changed to light-transmitting pixels 112, thereby ensuring the user's usage experience.

[0035] In the embodiments of the present application, Figure 3, the adjacent pixel of the luminous pixel 111 is the light-transmitting pixel 112 , and the adjacent pixel of the light-transmitting pixel 112 is the luminous pixel 111 .

[0036] It can be understood that the luminous pixels 111 and the light-transmitting pixels 112 are evenly distributed in the first display area 11, which ensures the resolution of the first display area 11. That is, the light emission in the first display area 11 will be uniform. When the first display area 11 is in display mode, the light-transmitting pixels 112 of the first display area 11 that do not emit light are separated by the light-emitting pixels 111 that emit light, which can prevent users from observing that part of the first display area 11 does not emit light, so that the first display area 11 is no different from the second display area 12 in the eyes of users, and users can hardly notice that part of the pixels in the first display area 11 are changed to light-transmitting pixels 112, which ensures the user experience. The light-transmitting pixels 112 are evenly distributed in the first display area 11, which ensures the size of the photosensitive surface of the spectral chip 2, that is, ensures the wide-angle shooting of the display screen 1.

[0037] In the embodiment of the present application, two or more light-transmitting pixels 112 are disposed between adjacent light-emitting pixels 111 .

[0038] It is understandable that increasing the number of light-transmitting pixels 112 at the first display area 11 can improve the light transmittance of the first display area 11 and ensure the light-sensing quality of the spectrum chip 2. It should be noted that the number of light-transmitting pixels 112 between two adjacent light-emitting pixels 111 should not be too large to avoid too low resolution at the first display area 11. Preferably, the number of light-transmitting pixels 112 between two adjacent light-emitting pixels 111 is less than 10.

[0039] In the embodiment of the present application, two or more luminous pixels 111 are arranged between two adjacent light-transmitting pixels 112 .

[0040] It is understandable that increasing the number of luminous pixels 111 at the first display area 11 can improve the resolution of the first display area 11 and ensure the imaging quality of the first display area 11. It should be noted that the number of luminous pixels 111 between two adjacent light-transmitting pixels 112 should not be too large to avoid affecting the photosensitivity of the spectrum chip 2. Preferably, the number of luminous pixels 111 between two adjacent light-transmitting pixels 112 is less than 5.

[0041] In one embodiment of the present application, the orthographic projection of the spectral chip 2 on the display screen 1 overlaps with the first display area 11 .

[0042] It is understandable that the spectrum chip 2 is installed on the back of the display screen 1 so that the spectrum chip 2 completely overlaps with the back of the first display area 11, and the orthographic projection of the spectrum chip 2 on the display screen 1 overlaps with the first display area 11. Then, all the light incident on the first display area 11 from the outside will be received by the spectrum chip 2, so that the spectrum chip 2 can accurately and comprehensively receive the light incident on the first display area 11, thereby ensuring the light sensitivity of the spectrum chip 2.

[0043] In one embodiment of the present application, the spectral chip 2 includes a plurality of photosensitive pixels, and the photosensitive areas of the plurality of photosensitive pixels are arranged one by one opposite to the plurality of light-transmitting pixels 112 .

[0044] It can be understood that the photosensitive pixels and the transparent pixels 112 of the spectral chip 2 are aligned one by one so that the photosensitive area of ​​the photosensitive pixel is opposite to the transparent pixel 112. Then, the light transmitted through the transparent pixel 112 will be incident on the photosensitive area of ​​the photosensitive pixel, so that the spectral chip 2 can accurately receive the light incident on the first display area 11, thereby ensuring the photosensitivity quality of the spectral chip 2.

[0045] In one embodiment of the present application, the orthographic projection of the photosensitive area of ​​the photosensitive pixel on the display screen 1 coincides with the light-transmitting pixel 112 .

[0046] It can be understood that by aligning and overlapping the photosensitive area of ​​the photosensitive pixel and the transparent pixel 112, that is, the orthographic projection of the photosensitive area on the display screen 1 overlaps with the corresponding transparent pixel 112, the light incident on the first display area 11 through the transparent pixel 112 will be incident on the photosensitive area of ​​the photosensitive pixel, ensuring that the spectral chip 2 can accurately and completely receive the light incident on the first display area 11, thereby ensuring the photosensitivity of the spectral chip 2.

[0047] In one embodiment of the present application, the display screen 1 is provided with a fingerprint recognition area, the spectral chip 2 is opposite to the fingerprint recognition area, and the spectral chip 2 is suitable for receiving light reflected by an external object approaching or contacting the fingerprint recognition area to obtain fingerprint information of the external object.

[0048] It is understandable that the spectral chip 2 is placed at a position directly opposite to the fingerprint identification area, so that the spectral chip 2 can receive light reflected by an external object close to or in contact with the fingerprint identification area. The reflected light carries the fingerprint information of the external object. The spectral chip 2 processes the reflected light to obtain the fingerprint imaging data of the external object, and then the fingerprint information of the external object can be obtained. Compared with the fingerprint identification technology in the related art, the fingerprint identification using the spectral chip 2 can effectively improve the resolution of fingerprint identification. At the same time, the spectral chip 2 can be used not only for photosensitive imaging, but also for fingerprint identification. The function of the spectral chip 2 is increased, so that the spectral chip 2 integrates the two functions of photosensitive imaging and fingerprint identification, which can further simplify the structure of the display screen 1 or the electronic device having the display screen 1.

[0049] It can be understood that when fingerprint recognition is performed, the luminous pixel 111 at the fingerprint recognition area will emit light, and when the light is emitted to the finger, it will produce reflected light, and the reflected light will be incident on the spectral chip 2 through the transparent pixel 112, so that the spectral chip 2 can obtain the imaging information of the finger fingerprint, and the fingerprint information of the finger can be obtained by analyzing the imaging information.

[0050] It can be understood that the fingerprint identification area is located in the first display area 11 .

[0051] It is understandable that only when the display screen 1 is in fingerprint recognition mode, the luminous pixel 111 at the fingerprint recognition area will actively emit white light. In other cases, it will emit light according to the imaging data of the spectral chip 2 or the RGB value given by the terminal.

[0052] In one embodiment of the present application, the spectrum chip 2 is attached to the back of the display screen 1 .

[0053] It is understandable that the spectral chip 2 is attached to the back of the display screen 1 so that the spectral chip 2 can receive external light at the back of the display screen 1 , while the user cannot observe the existence of the spectral chip 2 at the front of the display screen 1 .

[0054] Exemplarily, the spectral chip 2 may be attached to the back of the display screen 1 by pasting, or the spectral chip 2 may be attached to the back of the display screen 1 by welding.

[0055] In one embodiment of the present application, a light shielding member is provided at the edge of the light-transmitting pixel 112 and / or at the edge of the light-emitting pixel 111 .

[0056] It can be understood that by setting a shading member adjacent to the transparent pixel 112 and the luminous pixel 111 and / or setting a shading member adjacent to the luminous pixel 111 and the transparent pixel 112, it is possible to effectively avoid the luminous pixel 111 from affecting the transparent pixel 112 when emitting light, thereby reducing the impact of external light on the spectral chip 2 when transmitting through the transparent pixel 112.

[0057] In one embodiment of the present application, Figure 5 , Figure 6 and Figure 7 The spectral chip 2 includes a photosensitive layer 210, a filter layer 220 and a light shielding layer 230. The photosensitive layer 210 includes a plurality of spaced photosensitive units 211. The filter layer 220 is disposed on one side of the photosensitive layer 210, and the filter layer 220 is located on the photosensitive path of the photosensitive layer 210. The filter layer 220 is formed with a plurality of filter units, and the filter units include a plurality of filter films. The plurality of filter units are arranged one by one opposite to the plurality of photosensitive units 211, and the filter films of at least two filter units have different thicknesses. The light shielding layer 230 and the filter layer 220 are located on the same side of the photosensitive layer 210, and the orthographic projection of the light shielding layer 230 on the photosensitive layer 210 is located between any two adjacent photosensitive units 211.

[0058] According to the spectrum chip 2 of the present application, the filter layer 220 is located on the photosensitive path of the photosensitive layer 210, and the light is incident on the photosensitive layer 210 after being filtered by the filter layer 220. The multiple photosensitive units 211 of the photosensitive layer 210 and the multiple filter units of the filter layer 220 are arranged one by one relative to each other, and the light incident on one of the filter units will be incident on the corresponding photosensitive unit 211 after passing through the filter unit to achieve photosensitivity. Since the positive projection of the light shielding layer 230 on the photosensitive layer 210 is located between any two adjacent photosensitive units 211, when the light passes through one of the filter units and is incident on the corresponding one of the photosensitive units 211, the light shielding layer 230 can block the light, and the light shielding layer 230 can limit the light to propagate between one of the filter units and the corresponding photosensitive unit 211, which can effectively prevent the light incident on one of the filter units from being incident on other photosensitive units 211. That is, the present application sets the light shielding layer 230 between two adjacent photosensitive units 211, so that the light incident on the filter unit, after being filtered by the filter unit, will only be incident on the photosensitive unit 211 arranged opposite to the filter unit, thereby effectively preventing light crosstalk between two adjacent pixel units of the spectrum chip 2. Compared with setting a grid, the present application lays the light shielding layer 230 on one side of the photosensitive layer 210, so that the light shielding layer 230 and the filter layer 220 are on the same side of the photosensitive layer 210, which is simple in process and effectively reduces the manufacturing cost of the spectrum chip 2. The light shielding layer 230 can block the light at the luminous pixel 111 when it is incident on the photosensitive unit 211 of the spectrum chip 2, which can effectively prevent the light from affecting the photosensitivity of the spectrum chip 2 when the luminous pixel 111 emits light.

[0059] It can be understood that the photosensitive unit 211 can be understood as the photosensitive area mentioned above.

[0060] It is understandable that the light shielding layer 230 is arranged around the photosensitive path of the photosensitive unit 211, so only the light propagating along the path of the photosensitive unit 211 can be incident on the photosensitive unit 211, and the filter unit opposite to the photosensitive unit 211 is on the photosensitive path of the photosensitive unit 211. Then, only the light incident on the filter unit arranged opposite to the photosensitive unit 211 can be incident on the photosensitive unit 211, and the light incident on other filter units cannot be incident on the photosensitive unit 211, thereby ensuring the effect of preventing light crosstalk.

[0061] It can be understood that the photosensitive unit 211 and the filter unit arranged opposite thereto constitute a pixel unit. The present application can avoid the phenomenon of light crosstalk between two adjacent pixel units by setting the light shielding layer 230.

[0062] In one embodiment of the present application, Figure 5 , Figure 6 and Figure 7The light shielding layer 230 is disposed around the photosensitive unit 211 on the orthographic projection of the photosensitive layer 210 .

[0063] It is understandable that the light shielding layer 230 is arranged around the photosensitive unit 211, so that the positive projection of the light shielding layer 230 on the photosensitive layer 210 surrounds the photosensitive unit 211. In other words, under the shielding effect of the light shielding layer 230, light can only enter from directly above the photosensitive unit 211, and the light shielding layer 230 can effectively shield the light incident on other photosensitive units 211, which can effectively prevent the phenomenon of light crosstalk between two adjacent pixel units of the spectrum chip 2.

[0064] It can be understood that the light-shielding layer 230 is arranged around the photosensitive unit 211, that is, a light-shielding structure is formed around the photosensitive unit 211, so that light can only enter the photosensitive unit 211 along the photosensitive path of the photosensitive unit 211, and the light on the photosensitive path of the non-photosensitive unit 211 will be blocked by the light-shielding layer 230 and cannot enter the photosensitive unit 211, thereby effectively preventing the phenomenon of light crosstalk between two adjacent pixel units of the spectral chip 2.

[0065] In one embodiment of the present application, Figure 5 The light shielding layer 230 is located between the filter layer 220 and the photosensitive layer 210 .

[0066] It can be understood that after the light passes through the filter unit, part of the light enters the photosensitive unit 211 along the photosensitive path of the photosensitive unit 211, and the other part of the light may enter the adjacent filter unit. Since the shading layer 230 is located between the filter layer 220 and the photosensitive layer 210, the other part of the light will be blocked by the shading layer 230 after passing through the adjacent filter unit and cannot enter the adjacent photosensitive unit 211, thereby avoiding interference with the adjacent photosensitive unit 211, and effectively preventing the occurrence of light crosstalk between two adjacent pixel units of the spectral chip 2.

[0067] In one embodiment of the present application, the light shielding layer 230 is attached to the photosensitive layer 210 , and the orthographic projection of the light shielding layer 230 on the photosensitive layer 210 is adjacent to the edge of the photosensitive unit 211 .

[0068] It can be understood that the light-shielding layer 230 is attached to the photosensitive layer 210. When light passes through the filter unit and enters the photosensitive unit 211, since the positive projection of the light-shielding layer 230 on the photosensitive layer 210 is adjacent to the edge of the photosensitive unit 211, that is, the light-shielding layer 230 is arranged closely to the photosensitive unit 211, and there is no gap between the light-shielding layer 230 and the photosensitive unit 211, the light cannot enter the photosensitive unit 211 from the light-shielding layer 230 and between the light-shielding layer 230 and the photosensitive unit 211, so that the light can only enter the photosensitive unit 211 from the light-sensitive path of the photosensitive unit 211, that is, the light-shielding layer 230 can effectively block the light that should have entered the adjacent photosensitive unit 211, thereby effectively preventing the phenomenon of light crosstalk between two adjacent pixel units of the spectral chip 2.

[0069] In one embodiment of the present application, a light shielding layer 230 is provided at the gap between any two photosensitive units 211 .

[0070] It can be understood that the gap between any two photosensitive units 211 is covered with a light-shielding layer 230, that is, there is no light-transmitting gap between any two photosensitive units 211, so that light cannot enter the photosensitive unit 211 from the gap between the two photosensitive units 211, and light can only enter the photosensitive unit 211 from the side of the photosensitive unit 211 toward the filter unit, that is, light can only enter the photosensitive unit 211 along the light sensing path of the photosensitive unit 211, and cannot enter the adjacent photosensitive unit 211 through the gap, that is, light can only enter the photosensitive unit 211 after being filtered by the filter unit opposite to the photosensitive unit 211, and light filtered by the filter unit opposite to the photosensitive unit 211 can only enter the photosensitive unit 211, thereby effectively preventing the phenomenon of light crosstalk between the two pixel units of the spectral chip 2.

[0071] In one embodiment of the present application, Figure 5 and Figure 6 The spectral chip 2 includes a plurality of light-gathering units 240 . The light-gathering units 240 are disposed on a side of the filter layer 220 away from the photosensitive layer 210 . The plurality of light-gathering units 240 are disposed opposite to the plurality of photosensitive units 211 .

[0072] It can be understood that the multiple focusing units 240 and the multiple photosensitive units 211 are arranged one by one, that is, each photosensitive unit 211 corresponds to a focusing unit 240, and the filtering unit is located between the focusing unit 240 and the photosensitive unit 211. The light passes through the focusing unit 240 and the filtering unit in sequence and then enters the photosensitive unit 211. The focusing unit 240 can play a focusing role, thereby increasing the light flux entering the filtering unit, thereby increasing the light flux entering the photosensitive unit 211.

[0073] It can be understood that the side of the light focusing unit 240 facing the filter layer 220 is a planar structure, so that the light focusing unit 240 can be better installed on the filter layer 220. The side of the light focusing unit 240 away from the filter layer 220 is a curved structure, and the side of the light focusing unit 240 away from the filter layer 220 is convex in the direction away from the filter layer 220, so that the light focusing unit 240 can focus the light entering the filter unit, thereby enhancing the light flux entering the filter unit and the photosensitive unit 211.

[0074] In one embodiment of the present application, Figure 6 The light shielding layer 230 is located on the side of the filter layer 220 away from the photosensitive unit 211 .

[0075] It is understandable that the light shielding layer 230 is disposed on the side of the filter layer 220 away from the photosensitive unit 211, and the orthographic projection of the light shielding layer 230 on the photosensitive layer 210 is located between any two adjacent photosensitive units 211, so that light can only enter the filter unit from the portion of the filter layer 220 directly opposite to the photosensitive unit 211, and the light directly enters the photosensitive unit 211 after being filtered by the filter unit. In other words, by disposing the light shielding layer 230, light can only enter from the portion of the filter layer 220 directly opposite to the photosensitive unit 211, and when the light passes through the filter unit of the filter layer 220, it is at a certain distance from the adjacent photosensitive unit 211, and thus it is difficult to be incident on the adjacent photosensitive unit 211, and can only be incident on the photosensitive unit 211 opposite to the filter unit, thereby effectively preventing the phenomenon of light crosstalk between two adjacent pixel units of the spectral chip 2.

[0076] In one embodiment of the present application, the light shielding layer 230 is disposed between the light focusing unit 240 and the light filtering layer 220 .

[0077] It can be understood that the shading layer 230 is arranged between the focusing unit 240 and the filter layer 220, so that after the light passes through the focusing unit 240, under the shielding effect of the shading layer 230, the light can only be incident on the filter unit directly opposite to the focusing unit 240, that is, the position where the light is incident on the filter layer 220 is at a certain distance from the adjacent photosensitive unit 211, so it is difficult for the light to be incident on the adjacent filter unit after being filtered by the filter layer 220, thereby effectively preventing the phenomenon of light crosstalk between two adjacent pixel units of the spectral chip 2.

[0078] In one embodiment of the present application, the orthographic projection of the light shielding layer 230 on the filter layer 220 is adjacent to the orthographic projection of the light focusing unit 240 on the filter layer 220 .

[0079] It can be understood that the light shielding layer 230 is arranged around the light focusing unit 240, so that the orthographic projection of the light shielding layer 230 on the filter layer 220 is adjacent to the orthographic projection of the light focusing unit 240 on the filter layer 220. It can be understood that the light shielding layer 230 is arranged adjacent to the light focusing unit 240, and only the light passing through the light focusing unit 240 can enter the filter layer 220, and after the light focusing unit 240 focuses the light, the light will directly enter the filter unit directly opposite to it, and finally directly enter the photosensitive unit 211. That is, through the arrangement of the light shielding layer 230, the light is transmitted along the light focusing unit 240 and the filter unit arranged opposite to the light focusing unit 240, and finally enters the photosensitive unit 211, so that the position where the light is incident on the filter layer 220 is a certain distance away from the adjacent photosensitive unit 211, thereby effectively avoiding the phenomenon of light crosstalk between two adjacent pixel units of the spectral chip 2.

[0080] In one embodiment of the present application, the orthographic projection of the light shielding layer 230 on the filter layer 220 partially overlaps with the orthographic projection of the light focusing unit 240 on the filter layer 220 .

[0081] It can be understood that the shading layer 230 is extended to the side close to the focusing unit 240, so that part of the shading layer 230 is located between the focusing unit 240 and the filter layer 220, that is, the edge of the shading layer 230 coincides with the edge of the focusing unit 240 in the direct projection of the filter layer 220, so that light can only be incident on the filter unit through the center position of the focusing unit 240, further increasing the distance between the position where the light is incident on the filter unit and the adjacent photosensitive unit 211, and effectively avoiding the phenomenon of light crosstalk between two adjacent pixel units of the spectral chip 2.

[0082] It is understandable that there is a certain distance between the light shielding layer 230 and the central axis of the light focusing unit 240 , that is, the light shielding layer 230 will not completely block the light path between the light focusing unit 240 and the filter unit.

[0083] In one embodiment of the present application, the orthographic projection of the light shielding layer 230 on the filter layer 220 is adjacent to or partially overlaps with the orthographic projection of the photosensitive unit 211 on the filter layer 220 .

[0084] It is understandable that the light shielding layer 230 is aligned with the photosensitive unit 211, or the light shielding layer 230 is extended to one side of the photosensitive unit 211, so that the filter unit is located between the photosensitive unit 211 and part of the light shielding layer 230. That is, the positive projection of the light shielding layer 230 on the filter layer 220 is adjacent to or partially overlapped with the positive projection of the photosensitive unit 211 on the filter layer 220. Then, after the light passes through the focusing unit 240, the light can only be incident on the filter unit at the area directly opposite to the photosensitive unit 211, which can effectively avoid the phenomenon of light crosstalk between two adjacent pixel units of the spectral chip 2.

[0085] It can be understood that when the orthographic projection of the light-shielding layer 230 on the filter layer 220 partially overlaps with the orthographic projection of the photosensitive unit 211 on the filter layer 220, the light-shielding layer 230 limits the light-sensitive path of the photosensitive unit 211, so that the light is incident on the middle position of the photosensitive unit 211, which can more effectively prevent the light from being incident on the adjacent photosensitive unit 211.

[0086] In one embodiment of the present application, the orthographic projection of the light shielding layer 230 on the photosensitive layer 210 is adjacent to or partially overlaps with the photosensitive unit 211 .

[0087] It can be understood that when light is incident on the filter layer 220, since the positive projection of the light-shielding layer 230 on the photosensitive layer 210 is adjacent to or partially overlaps with the photosensitive unit 211, the light can only be incident on the filter unit or part of the filter unit directly opposite to the photosensitive unit 211, thereby effectively avoiding the phenomenon of light crosstalk between two adjacent pixel units of the spectral chip 2.

[0088] It is understandable that when the orthographic projection of the photosensitive layer 210 partially overlaps with the photosensitive unit 211 , the light shielding layer 230 further limits the incident area of ​​light, which can more effectively prevent light from being incident on adjacent photosensitive units 211 .

[0089] In one embodiment of the present application, the photosensitive unit 211 is located within the orthographic projection of the light focusing unit 240 on the photosensitive layer 210 .

[0090] It is understandable that the photosensitive unit 211 is located within the orthographic projection of the light focusing unit 240 on the photosensitive layer 210 , so that light is incident into the photosensitive unit 211 after being focused by the light focusing unit 240 .

[0091] It is understandable that the center line of the photosensitive unit 211 coincides with the center line of the focusing unit 240 , ensuring that the focusing unit 240 can allow the focused light to enter the photosensitive unit 211 , thereby increasing the light flux entering the photosensitive unit 211 .

[0092] According to an embodiment of the second aspect of the present application, an electronic device includes the above-mentioned imaging display screen assembly.

[0093] According to the electronic device of the present application, by setting a spectral chip 2 on the back of the display screen 1 and using the spectral chip 2 for imaging, the display screen 1 has an imaging function. At the same time, the spectral chip 2 is used to replace the front camera, and the structure of the display screen 1 is optimized, so that a true full screen can be achieved, and the aesthetics of the display screen 1 is improved. At the same time, since the first display area 11 includes both luminous pixels 111 and light-transmitting pixels 112, while the spectral chip 2 receives external light through the light-transmitting pixels 112, the luminous pixels 111 of the first display area 11 can emit light according to the imaging data, so that the display screen 1 can image (emit light) while shooting (sensing), which will not affect the user's use.

[0094] In one embodiment of the present application, the spectral chip 2 is located on the top of the electronic device.

[0095] It can be understood that the spectral chip 2 is set to the top position of the electronic device, that is, the translucent pixels 112 of the first display area 11 are also at the top position of the electronic device, so that the light received by the spectral chip 2 is incident on the display screen 1 through the top of the electronic device, and the camera in the related technology is also set at the top of the electronic device. In this embodiment, the position design of the spectral chip 2 makes the shooting position of the electronic device still at the top, which will not change the user's existing habits and improve the user's experience.

[0096] In one embodiment of the present application, the electronic device includes a control component, and the control component is configured to: control the luminous pixels 111 of the display screen 1 to emit light while the spectral chip 2 receives light transmitted through the light-transmitting pixels 112 .

[0097] It can be understood that when the control component controls the spectral chip 2 to receive light transmitted through the light-transmitting pixel 112, it means that the electronic device is in the imaging mode at this time. The control component will simultaneously control the luminous pixel 111 of the display screen 1 to emit light based on the imaging data of the spectral chip 2, so that the imaging display screen component can emit light and form an image while being sensitive to light.

[0098] According to an embodiment of the third aspect of the present application, Figure 4 , an imaging method of an electronic device includes:

[0099] Step 101: Determine whether the electronic device is in a front camera mode;

[0100] Step 102, acquiring imaging data of the spectral chip 2, wherein the imaging data is the RGB value obtained by splitting the light after the photosensitive pixels of the spectral chip 2 receive the light;

[0101] Step 103: Control the operation of the display screen 1 of the electronic device based on the imaging data.

[0102] According to the imaging method of the electronic device of the present application, the current mode information of the electronic device is obtained to determine whether the electronic device is in the front camera mode. When it is determined that the electronic device is in the front camera mode, the imaging data of the spectral chip 2 is obtained. Since the imaging data is the RGB value obtained after the photosensitive pixels of the spectral chip 2 receive the light transmitted through the light-transmitting pixels 112 and then the display screen 1 of the electronic device is controlled based on the imaging data, the display screen 1 emits light and forms an image according to the imaging data, so that the display screen 1 can perform imaging while sensing and shooting.

[0103] It is understandable that after the spectral chip 2 receives the light transmitted through the light-transmitting pixel 112 and obtains imaging data, the electronic device can store the imaging data for subsequent viewing by the user.

[0104] It can be understood that the control component of the electronic device can detect the current mode of the electronic device. When it is detected that the electronic device is in the front camera mode, the control component will obtain the real-time imaging data of the spectral chip 2, and at the same time control the display screen 1 of the electronic device to perform luminous imaging based on the real-time imaging data, so as to display the external scene on the display screen 1.

[0105] It is understandable that the electronic device includes a display mode, a fingerprint recognition mode and an imaging mode. When the electronic device is in the display mode, the display screen 1 is controlled to emit light according to the RGB value provided by the control component; when the electronic device is in the fingerprint recognition mode, the light-emitting pixel 111 at the fingerprint recognition area is controlled to emit strong white light, and the white light is reflected after contacting the finger, and the reflected light is incident on the spectrum chip 2 through the light-transmitting pixel 112, so that the spectrum chip 2 can obtain imaging data related to the finger fingerprint, and the control component can obtain the finger fingerprint image according to the imaging data related to the finger fingerprint, and compare the finger fingerprint image with the pre-stored target fingerprint image to determine whether the current finger fingerprint matches the target fingerprint image.
