Description

Technical Field

[0001] The embodiments of the present invention relate to the field of display technology, and in particular to a terminal device. Background Art

[0002] OLED (Organic Light-Emitting Diode) is called an organic electroluminescent diode. OLED display technology has many advantages such as all-solid state, active light emission, high contrast ratio, ultra-thin, low power consumption, fast response speed, wide working range, easy implementation of flexible display and 3D display, etc., which makes it currently applied in many display devices, such as TVs and mobile devices. With technological progress and the increasing demand of consumers for large-screen mobile phones, mobile phone manufacturers have been committed to improving the screen-to-body ratio of mobile phones. From the so-called borderless mobile phones to notch screens, then to waterdrop screens and the design of pop-up cameras, and the launch of foldable screens, the development trend of mobile phones towards true full-screen is relatively clear, and under-screen camera technology is considered a killer solution for true full-screen.

[0003] However, the inventors found that there are at least the following problems in the prior art: the display area above the under-screen camera has pixels, which affects the transmittance of this area, resulting in insufficient light input for the under-screen camera and unclear imaging of the front camera. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a terminal device that can improve the shooting performance without affecting the display effect of the screen.

[0005] To solve the above technical problems, the embodiments of the present invention provide a terminal device, including:

[0006] A light-emitting layer and a cover plate stacked in sequence, further including a camera unit, and the camera unit and the light-emitting layer are on the same side of the cover plate; the light-emitting layer includes a first light-emitting layer and a second light-emitting layer, and the first light-emitting layer can move from a first preset position to a second preset position; when the first light-emitting layer is at the first preset position, the first positive projection area of the first light-emitting layer in a first direction coincides with the second positive projection area of the camera unit in the first direction, where the first direction is the stacking direction of the light-emitting layer and the cover plate; when the first light-emitting layer is at the second preset position, the third positive projection area of the light-emitting layer in the first direction does not coincide with the second positive projection area at least partially, or when the first light-emitting layer is at the second preset position, the positive projection area of the first light-emitting layer on the cover plate does not coincide with the second positive projection area at least partially, the second light-emitting layer includes a first sub-light-emitting layer and a second sub-light-emitting layer facing the second positive projection area, and the pixel density of the second sub-light-emitting layer is less than the pixel density of the first sub-light-emitting layer.

[0007] In the embodiment of the present invention, compared with the prior art, by providing a movable first light-emitting layer, when the terminal device is in the display state, the first light-emitting layer is moved to the first preset position. At this time, in the direction of the light-emitting layer pointing to the cover plate, the first orthographic projection area of the first light-emitting layer coincides with the second orthographic projection area of the imaging unit. That is to say, there is a light-emitting layer above the imaging unit so that it can be displayed, thus realizing the full-screen display of the terminal device and improving the display effect of the terminal device; when the terminal device is in the shooting state, the first light-emitting layer is moved to the second preset position. At this time, there are two situations: 1. In the direction of the light-emitting layer pointing to the cover plate, at least part of the third orthographic projection area of the light-emitting layer does not coincide with the second orthographic projection area. That is to say, when the terminal device is in the shooting state, at least part of the area above the imaging unit is not provided with a light-emitting layer, which can effectively prevent the light-emitting layer from blocking the external light from entering the imaging unit and improve the light transmittance. Thus, while the terminal device satisfies the full-screen display, the shooting performance of the imaging unit is improved; 2. At least part of the first orthographic projection area does not coincide with the second orthographic projection area. The second light-emitting layer includes a first sub-light-emitting layer and a second sub-light-emitting layer facing the second orthographic projection area, and the pixel density of the second sub-light-emitting layer is less than that of the first sub-light-emitting layer. That is to say, at least part of the area above the imaging unit is not provided with the first light-emitting layer at this time. Although the second light-emitting layer has a second sub-light-emitting layer facing the second orthographic projection area, the pixel density of the second sub-light-emitting layer is less than that of the first sub-light-emitting layer, thereby improving the light transmittance of the second sub-light-emitting layer and enabling more light to enter the imaging unit. Furthermore, while the terminal device satisfies the full-screen display, the shooting performance of the imaging unit is also improved.

[0008] In addition, the first light-emitting layer can move from the first preset position to the second preset position along the second direction, where the second direction is perpendicular to the first direction; when the first light-emitting layer is at the first preset position, the first light-emitting layer is arranged between the second light-emitting layer and the imaging unit; when the first light-emitting layer is at the second preset position, at least part of the first light-emitting layer is outside the optical path of the imaging unit, where the direction of the optical path is the first direction.

[0009] In addition, the imaging unit includes a photosensitive layer and an optical lens arranged on the side of the photosensitive layer adjacent to the cover plate, and the first light-emitting layer is movably arranged in the imaging unit; when the first light-emitting layer is at the first preset position, the first light-emitting layer is located on the side of the optical lens away from the photosensitive layer; when the first light-emitting layer is at the second preset position, at least part of the first light-emitting layer is outside the optical path of the imaging unit, where the direction of the optical path is the first direction.

[0010] In addition, the second sub-light-emitting layer is disposed within the imaging unit, and the first sub-light-emitting layer and the second sub-light-emitting layer are rotatably connected; when the first light-emitting layer is located at the second preset position and the second sub-light-emitting layer rotates around the first sub-light-emitting layer to the third preset position, at least a part of the first light-emitting layer and the second sub-light-emitting layer is located outside the optical path.

[0011] In addition, the sum of the pixel density of the first light-emitting layer and the pixel density of the second sub-light-emitting layer is equal to the pixel density of the first sub-light-emitting layer.

[0012] In addition, the ratio of the pixel density of the first light-emitting layer to the pixel density of the second sub-light-emitting layer is between 1 and 4.

[0013] In addition, the first sub-light-emitting layer has a first pixel structure, the second sub-light-emitting layer has a second pixel structure, and the first light-emitting layer has a third pixel structure; when the first light-emitting layer is located at the first preset position, the orthographic projection pattern of the first pixel structure on the cover plate is a first pattern, the orthographic projection pattern of the second pixel structure on the cover plate is a second pattern, the orthographic projection pattern of the third pixel structure on the cover plate is a third pattern, and the shape of the pattern formed by superimposing the second pattern and the third pattern is the same as the shape of the first pattern.

[0014] In addition, the first light-emitting layer and the second light-emitting layer are disposed on the same layer; when the first light-emitting layer is located at the first preset position, the first light-emitting layer is located between the imaging unit and the cover plate; when the first light-emitting layer is located at the second preset position, at least a part of the light-emitting layer is located outside the optical path of the imaging unit, wherein the direction of the optical path is the first direction.

[0015] In addition, the imaging unit includes a photosensitive layer and an optical lens that are sequentially stacked, and the first light-emitting layer and the second light-emitting layer are disposed on the same layer; when the first light-emitting layer is located at the first preset position, the first light-emitting layer is located within the imaging unit and on the side of the optical lens away from the photosensitive layer; when the first light-emitting layer is located at the second preset position, at least a part of the light-emitting layer is located outside the optical path of the imaging unit, wherein the direction of the optical path is the first direction.

[0025] Currently, terminal products need to place light - sensitive modules such as cameras under the screen. However, the existing screen has a light - emitting material layer, resulting in a low light transmittance of the terminal product. When light - sensitive modules such as cameras collect external light signals, the screen cannot ensure sufficient light transmission through the screen body, making it difficult for light - sensitive modules such as cameras to collect sufficient light, thus affecting the shooting performance of light - sensitive modules such as cameras.

[0026] In view of the above problems, the present invention provides a terminal device. When the first light - emitting layer is located at a first preset position, the first orthographic projection area of the first light - emitting layer on the cover plate coincides with the second orthographic projection area of the imaging unit on the cover plate; when the first light - emitting layer is located at a second preset position, the third orthographic projection area of the light - emitting layer on the cover plate and the second orthographic projection area are at least partially non - coincident, or the orthographic projection area of the first light - emitting layer on the cover plate and the second orthographic projection area are at least partially non - coincident. The second light - emitting layer includes a first sub - light - emitting layer and a second sub - light - emitting layer facing the second orthographic projection area, and the pixel density of the second sub - light - emitting layer is less than the pixel density of the first sub - light - emitting layer. It can improve the shooting performance without affecting the display effect of the screen.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those of ordinary skill in the art can understand that in the embodiments of the present invention, many technical details are provided for the readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented.

[0031] The first embodiment of the present invention relates to a terminal device 100. The structural schematic diagram of the terminal device 100 in this embodiment is as Figure 1 shown and includes:

[0032] A light-emitting layer 1 and a cover plate 2 are stacked in sequence, and further includes a camera unit 3. The camera unit 3 and the light-emitting layer 1 are on the same side of the cover plate 2. The light-emitting layer 1 includes a first light-emitting layer 11 and a second light-emitting layer 12. The first light-emitting layer 11 can move from a first preset position N1 to a second preset position N2. When the first light-emitting layer 11 is located at the first preset position N1, in the direction of the light-emitting layer 1 pointing to the cover plate 2, the first orthographic projection area of the first light-emitting layer 11 coincides with the second orthographic projection area of the camera unit 3. When the first light-emitting layer 11 is located at the second preset position N2, in the direction of the light-emitting layer 1 pointing to the cover plate 2, at least part of the third orthographic projection area of the light-emitting layer 1 does not coincide with the second orthographic projection area.

[0033] In practical applications, the light-emitting layer 1 includes a buffer layer, an N-GaN layer (N-type gallium nitride layer), a multi-quantum well layer, a P-GaN layer (P-type gallium nitride layer), and an ITO layer (indium tin oxide layer) stacked in sequence. In addition, the cover plate 2 in this embodiment is a glass cover plate.

[0034] Compared with the prior art, the embodiment of the present invention has at least the following advantages: By providing the movable first light-emitting layer 11, when the terminal device 100 is in the display state, the first light-emitting layer 11 is moved to the first preset position N1. At this time, the first orthographic projection area of the first light-emitting layer 11 on the cover plate 2 coincides with the second orthographic projection area of the camera unit 3 on the cover plate 2. That is to say, the area above the camera unit 3 is provided with a light-emitting layer so as to be displayable, and thus full-screen display of the terminal device 100 is realized, improving the display effect of the terminal device 100. When the terminal device 100 is in the shooting state, the first light-emitting layer 11 is moved to the second preset position N2. At this time, at least part of the third orthographic projection area of the light-emitting layer 1 on the cover plate 2 does not coincide with the second orthographic projection area. That is to say, when the terminal device 100 is in the shooting state, at least part of the area above the camera unit 3 is not provided with the light-emitting layer 1, which can effectively prevent the light-emitting layer 1 from blocking external light from entering the camera unit 3, improving the light transmittance, so that while the terminal device 100 satisfies full-screen display, the shooting performance of the camera unit is improved.

[0035] Please continue to refer to Figure 1 a and Figure 1 b. The first light-emitting layer 11 and the second light-emitting layer 12 in this embodiment are arranged on the same layer: As Figure 1 shown in a, the camera unit 3 is in the sleep state, and the light-emitting layer 1 above the camera unit 3 is in the normal unfolded state, and a complete visible picture content can be displayed. As Figure 1As shown in Figure b, the imaging unit 3 is in a working state, and the light-emitting layer 1 above the camera has undergone a physical bending operation (bending the first light-emitting layer 11 to overlap with the second light-emitting layer 12), so that the area above the imaging unit 3 is not blocked by the light-emitting layer 1, enabling the imaging unit 3 to receive more light for better lens imaging. It is worth mentioning that when the light-emitting layer 1 is in a bent state, the displayed image in the bent area may be incomplete. At this time, the terminal device 100 can perform special processing according to the current displayed content, such as shortening and displacing the status bar area, etc., thereby improving the user experience.

[0036] It is worth mentioning that the terminal device 100 in this embodiment has a drive control unit (not shown in the figure), which can control the light-emitting layer 1 to be in an extended state or a bent state. Further, when the drive control unit controls the light-emitting layer 1 to be in a bent state, it is not necessary to make the first light-emitting layer 11 in a state of being bent nearly 180 degrees to overlap with the second light-emitting layer 12 as shown in Figure 1 Figure b. It is only necessary to ensure that the first light-emitting layer 11 is bent so as not to block or only partially block the light path of the imaging unit 3.

[0037] The second embodiment of the present invention relates to a terminal device 200. This embodiment is substantially the same as the first embodiment, and the main difference is that: in this embodiment, as Figure 2 shown, the first light-emitting layer 11 can move along the first direction X from the first preset position M1 to the second preset position M2, where the first direction X is a direction perpendicular to the stacking direction of the light-emitting layer 1 and the cover plate 2; when the first light-emitting layer 11 is located at the first preset position M1, the first light-emitting layer 11 is disposed between the second light-emitting layer 12 and the imaging unit 3; when the first light-emitting layer 11 is located at the second preset position M2, at least part of the orthographic projection area of the first light-emitting layer 11 on the cover plate 2 does not coincide with the second orthographic projection area. The second light-emitting layer 12 includes a first sub-light-emitting layer 121 and a second sub-light-emitting layer 122 facing the second orthographic projection area, and the pixel density of the second sub-light-emitting layer 122 is less than that of the first sub-light-emitting layer 121.

[0038] Specifically, the first light-emitting layer 11 and the second light-emitting layer 12 in this embodiment are not arranged on the same layer. The first light-emitting layer 11 is disposed on the side of the second light-emitting layer 12 away from the substrate 1, and the first light-emitting layer 11 can move between the first preset position M1 and the second preset position M2 along the first direction X (the first light-emitting layer 11 can just move to the first preset position M1 or the second preset position M2). As Figure 2 shown in Figure a, the imaging unit 3 is in a sleep state, and the light-emitting layer 1 above the imaging unit 3 is in a normal unfolded state, and can display a complete visible image content; as Figure 2As shown in Figure b, the imaging unit 3 is in the working state, and the first light-emitting layer 11 above the camera has been translated (the first light-emitting layer 11 is moved away from the light path of the imaging unit 3), so that the area above the imaging unit 3 is not blocked by the first light-emitting layer 11 (or only partially blocked by the first light-emitting layer 11), so that the imaging unit 3 can receive more light to better perform lens imaging. For ease of understanding, the following will be combined with Figure 3 Specifically describe how the terminal device 200 in this embodiment operates:

[0039] As Figure 3 shown in Figure a, it is a schematic structural diagram of the terminal device 200. The dotted circle 3000 is the installation position of the imaging unit 3, and the dotted box 5000 is the control unit. This control unit can comprehensively control and process components such as the first light-emitting layer 11, the second light-emitting layer 12, and the imaging unit 3 to improve the experience of the under-screen imaging technology application through a combined control method. As Figure 3 shown in Figure b, it is a schematic structural diagram of the control unit 5000. The control unit 5000 can collect and process the circuit information of components such as the first light-emitting layer 11, the second light-emitting layer 12, and the imaging unit 3, transfer it to the main processing unit of the terminal device 200 for judgment and processing, and perform various component and display or function processing according to the instructions issued by the main processing unit. Specifically, when the imaging unit 3 is in the sleep state, the control unit 5000 controls the first light-emitting layer 11 to be in the first preset position M1, and controls the first light-emitting layer 11 and the second light-emitting layer 12 to emit light to ensure the display effect of the terminal device 200; when the imaging unit 3 is in the working state, the control unit 5000 controls the first light-emitting layer 11 to be in the second preset position M2, and controls the second light-emitting layer 12 to emit light and the first light-emitting layer 11 not to emit light, so as to facilitate the maximum light intake and imaging processing of the under-screen imaging unit 3.

[0040] It is worth mentioning that this embodiment does not specifically limit the movement mode of the first light-emitting layer 11. For example, the first light-emitting layer 11 can move in the X direction through a slide rail, etc. Other structures that can move the first light-emitting layer 11 along the first direction X between the first preset position M1 and the second preset position M2 are within the protection scope of this embodiment and can be set according to actual needs.

[0041] Please refer to Figure 4 , since the display effect of the terminal display area above the imaging unit 3 is the superposition display effect of the first light-emitting layer 11 and the second sub-light-emitting layer 122, in order to ensure that the display effect of the terminal display area above the imaging unit 3 is consistent with that of other display areas of the terminal device 200, this embodiment performs special processing on the pixel distribution of the first light-emitting layer 11 and the second sub-light-emitting layer 122 to further improve the display effect of the terminal device 200. Specifically, as Figure 4As shown in a, the first sub-light-emitting layer 121 has a first pixel structure 1210, such as Figure 4 As shown in b, the second sub-light-emitting layer 122 has a second pixel structure 1220, such as Figure 4 As shown in c, the first light-emitting layer 11 has a third pixel structure 110. When the first light-emitting layer 11 is located at the first preset position M1, the orthographic projection pattern of the first pixel structure 1210 on the cover plate 2 is the first pattern, the orthographic projection pattern of the second pixel structure 1220 on the cover plate 2 is the second pattern, and the orthographic projection pattern of the third pixel structure 110 on the cover plate 2 is the third pattern. The shape of the pattern formed after the second pattern and the third pattern are superimposed is the same as the shape of the first pattern.

[0042] More specifically, the first pixel structure 1210 includes a plurality of pixel groups 10 arranged in an array, and each pixel group 10 includes a red sub-pixel, a green sub-pixel, and a blue sub-pixel, such as Figure 4 The first pixel structure 1210 shown in a has a total of 16 pixel groups, and each row and each column has 4 pixel groups. Such as Figure 4 The second pixel structure 1220 shown in b has a total of 8 pixel groups, and two pixel groups in the previous row are staggered with two pixel groups in the next row. Such as Figure 4 The third pixel structure 110 shown in c has a total of 8 pixel groups, two pixel groups in the previous row are staggered with two pixel groups in the next row, and the setting positions of the two pixel groups in the first row are the same as the setting positions of the two pixel groups in the second row of the second pixel structure 1220. It can be understood that through the above structural settings, the shape of the pattern formed after the second pattern S2 and the third pattern S3 are superimposed is the same as the shape of the first pattern S1, that is, the second pixel structure 1220 and the first pixel structure 1210 can be superimposed to form the third pixel structure 110 to ensure that the display effect of the terminal display area above the imaging unit 3 is the same as that of other display areas of the terminal device 200.

[0043] It can be understood that Figure 4 The pixel arrangement structures of the first light-emitting layer 11, the first sub-light-emitting layer 121, and the second sub-light-emitting layer 122 shown are only an example of a feasible pixel arrangement method. In actual applications, other pixel arrangement structures can be set according to actual needs, as long as it is ensured that the shape of the pattern formed after the second pattern and the third pattern are superimposed is the same or approximately the same as the shape of the first pattern. This embodiment does not specifically limit the pixel arrangement methods of the first pixel structure 1210, the second pixel structure 1220, and the third pixel structure 110.

[0044] It is worth noting that Figure 4The sum of the pixel density of the first light-emitting layer 11 and the pixel density of the second sub-light-emitting layer 122 shown is equal to the pixel density of the first sub-light-emitting layer 121, and the pixel density of the first light-emitting layer 11 is equal to the pixel density of the second sub-light-emitting layer 122. In practical applications, the ratio of the pixel density of the first light-emitting layer 11 to the pixel density of the second sub-light-emitting layer 122 is between 1 and 4, and can be set according to actual needs. Such a ratio range setting can ensure a certain display effect of the second sub-light-emitting layer 122 while reducing the pixel density of the second sub-light-emitting layer 122 as much as possible to improve the shooting effect of the imaging unit 3. Preferably, the ratio of the pixel density of the first light-emitting layer 11 to the pixel density of the second sub-light-emitting layer 122 is 2.5. Such a ratio can make the display effect of the second sub-light-emitting layer 122 better and the shooting performance of the imaging unit 3 superior.

[0045] Please refer to Figure 5 , the second sub-light-emitting layer 122 includes a plurality of pixel regions 122A and a gap region 122B between adjacent pixel regions 122A, and a through hole 20 penetrating the second sub-light-emitting layer 122 is provided on the gap region 122B. Through such a structure setting, more light can enter the imaging unit 3 through the second sub-light-emitting layer 122 (compared with the second sub-light-emitting layer 122 without holes, light can also enter the imaging unit 3 from the through hole 20) without affecting the performance of the second self-light-emitting layer, thereby increasing the light input of the imaging unit 3.

[0046] It should be noted that Figure 5 each of the gap regions 122B shown has four circular through holes 20. In practical applications, the number of through holes 20 in each gap region 122B is not specifically limited in this embodiment and can be set according to actual needs. This embodiment also does not specifically limit the longitudinal cross-sectional shape of the through hole 20. The longitudinal cross-sectional shape of the through hole 20 can be Figure 5 the circular shape shown, or can be an oval, a regular polygon or an irregular shape, etc. This embodiment does not specifically limit the longitudinal cross-sectional shape of the through hole 20. It should also be noted that the size of the through hole 20 is not specifically limited in this embodiment and can be freely set according to actual needs and process difficulty.

[0047] In embodiments of the present invention, compared with the prior art, by providing a movable first light-emitting layer 11, when the terminal device 200 is in a display state, the first light-emitting layer 11 is moved to a first preset position M1. At this time, the first orthographic projection area of the first light-emitting layer 11 on the cover plate 2 coincides with the second orthographic projection area of the imaging unit 3 on the cover plate. That is to say, a light-emitting layer is provided in the area above the imaging unit 3 so as to be displayable, thereby realizing full-screen display of the terminal device 100 and improving the display effect of the terminal device 100; when the terminal device 200 is in a shooting state, the first light-emitting layer 11 is moved to a second preset position M2. At this time, the orthographic projection area of the first light-emitting layer 11 on the cover plate 2 does not coincide with the second orthographic projection area at least partially. The second light-emitting layer 12 includes a first sub-light-emitting layer 121 and a second sub-light-emitting layer 122 facing the second orthographic projection area. The pixel density of the second sub-light-emitting layer 122 is less than that of the first sub-light-emitting layer 121. That is to say, at this time, at least part of the area above the imaging unit is not provided with the first light-emitting layer 11. Although the second light-emitting layer 12 has the second sub-light-emitting layer 122 facing the second orthographic projection area, the pixel density of the second sub-light-emitting layer 122 is less than that of the first sub-light-emitting layer 121, thereby increasing the light transmittance of the second sub-light-emitting layer 122 and enabling more light to enter the imaging unit 3. Furthermore, while the terminal device satisfies full-screen display, the shooting performance of the imaging unit 3 is improved.

[0048] The third embodiment of the present invention relates to a terminal device 300. This embodiment is substantially the same as the first embodiment, and the main difference is that: in this embodiment, as Figure 6 shown, the imaging unit 3 includes a photosensitive layer 31 and an optical lens 32 provided on the side of the photosensitive layer 31 adjacent to the cover plate 2. The first light-emitting layer 11 is movably provided in the imaging unit 3; when the first light-emitting layer 11 is located at the first preset position P1, the first light-emitting layer 11 is located on the side of the optical lens 32 away from the photosensitive layer 31; when the first light-emitting layer 11 is located at the second preset position P2, the orthographic projection area of the first light-emitting layer 11 on the cover plate 2 does not coincide with the second orthographic projection area at least partially. The second light-emitting layer 12 includes a first sub-light-emitting layer 121 and a second sub-light-emitting layer 122 facing the second orthographic projection area. The pixel density of the second sub-light-emitting layer 122 is less than that of the first sub-light-emitting layer 121.

[0049] Specifically, the first light-emitting layer 11 and the second light-emitting layer 12 of this embodiment are not arranged on the same layer, and the first light-emitting layer 11 can rotate from the first preset position P1 to the second preset position P2 within the imaging unit 3. It can be understood that this embodiment does not specifically limit the movement mode of the first light-emitting layer 11. For example, the first light-emitting layer 11 can rotate within the imaging unit 3 through a rotating shaft, and other structures that can rotate the first light-emitting layer 11 from the first preset position P1 to the second preset position P2 are within the protection scope of this embodiment and can be set according to actual needs.

[0050] Further, as Figure 6 shown in Fig. a, the imaging unit 3 is in a sleep state, and the light-emitting layer 1 above the imaging unit 3 is in a normal unfolded state and can display the complete visible picture content; as Figure 6 shown in Fig. b, the imaging unit 3 is in a working state, and the first light-emitting layer 11 above the camera has performed a rotation operation (rotating the first light-emitting layer 11 away from the light path of the optical lens 32), so that the area above the optical lens 32 is not blocked by the first light-emitting layer 11 (or only partially blocked by the first light-emitting layer 11), thereby enabling the imaging unit 3 to receive more light for better lens imaging.

[0051] As Figure 7 shown, in another feasible embodiment, the second sub-light-emitting layer 122 is arranged within the imaging unit 3, and the first sub-light-emitting layer 121 and the second sub-light-emitting layer 122 are rotationally connected; when the first light-emitting layer 11 is located at the second preset position P2 and the second sub-light-emitting layer 122 rotates around the first sub-light-emitting layer 121 to the third preset position P3, at least part of the orthographic projection area of the first light-emitting layer 11 on the cover plate does not coincide with the second orthographic projection area, and at least part of the orthographic projection area of the second sub-light-emitting layer 122 on the cover plate 2 does not coincide with the second orthographic projection area. Through the setting of this structure, while ensuring the display effect of the terminal device 300, the light input amount of the imaging unit 3 can be further increased, thereby further improving the shooting performance of the imaging unit 3.

[0052] Specifically, as Figure 7 shown in Fig. a, the imaging unit 3 is in a sleep state, and the light-emitting layer 1 above the imaging unit 3 is in a normal unfolded state and can display the complete visible picture content; as Figure 7 shown in Fig. b, the imaging unit 3 is in a working state, and the first light-emitting layer 11 and the second sub-light-emitting layer 122 above the camera have performed a rotation operation (rotating both the first light-emitting layer 11 and the second sub-light-emitting layer 122 away from the light path of the optical lens 32), so that the area above the optical lens 32 is not blocked by the light-emitting layer 1 (or only partially blocked by the light-emitting layer 1), thereby enabling the imaging unit 3 to receive more light for better lens imaging.

[0053] It should be noted that the relevant technical details mentioned in the first embodiment and the second embodiment are still valid in this embodiment. To avoid repetition, they will not be elaborated here. Correspondingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment and the second embodiment.

[0054] Compared with the prior art, in the embodiment of the present invention, by providing a movable first light-emitting layer 11, when the terminal device 200 is in a display state, the first light-emitting layer 11 is moved to a first preset position P1. At this time, the first orthographic projection area of the first light-emitting layer 11 on the cover plate 2 coincides with the second orthographic projection area of the imaging unit 3 on the cover plate. That is to say, a light-emitting layer is provided in the area above the imaging unit 3 so as to be displayable, thereby realizing full-screen display of the terminal device 100 and improving the display effect of the terminal device 100; when the terminal device 200 is in a shooting state, the first light-emitting layer 11 is moved to a second preset position P2. At this time, at least part of the orthographic projection area of the first light-emitting layer 11 on the cover plate 2 does not coincide with the second orthographic projection area. The second light-emitting layer 12 includes a first sub-light-emitting layer 121 and a second sub-light-emitting layer 122 facing the second orthographic projection area. The pixel density of the second sub-light-emitting layer 122 is less than that of the first sub-light-emitting layer 121. That is to say, at this time, at least part of the area above the imaging unit is not provided with the first light-emitting layer 11. Although the second light-emitting layer 12 has a second sub-light-emitting layer 122 facing the second orthographic projection area, the pixel density of the second sub-light-emitting layer 122 is less than that of the first sub-light-emitting layer 121, thereby increasing the light transmittance of the second sub-light-emitting layer 122 and enabling more light to enter the imaging unit 3, and further improving the shooting performance of the imaging unit 3 while the terminal device satisfies full-screen display.

[0055] The fourth embodiment of the present invention relates to a terminal device 400. This embodiment is substantially the same as the third embodiment, and the main difference is that: in this embodiment, as Figure 8 shown, the imaging unit 3 includes a photosensitive layer 31 and an optical lens 32 provided on the side of the photosensitive layer 31 adjacent to the cover plate 2. The first light-emitting layer 11 and the second light-emitting layer 12 are provided on the same layer; when the first light-emitting layer 11 is located at a first preset position Q1, the first light-emitting layer 11 is located inside the imaging unit 3 and on the side of the optical lens 32 away from the photosensitive layer; when the first light-emitting layer 11 is located at a second preset position Q2, at least part of the third orthographic projection area of the light-emitting layer 1 on the cover plate 2 does not coincide with the second orthographic projection area.

[0056] Specifically, as Figure 8 shown in a, the imaging unit 3 is in a sleep state, and the light-emitting layer 1 above the imaging unit 3 is in a normal unfolded state and can display the complete visible picture content; as Figure 8As shown in Fig. b, the imaging unit 3 is in a working state, and the light-emitting layer 1 above the camera has undergone a physical bending operation (bending the first light-emitting layer 11 to the side of the optical lens 32), so that there is no light shielding of the light-emitting layer 1 above the optical lens 32, enabling the imaging unit 3 to receive more light for better lens imaging.

[0057] It is worth mentioning that the terminal device 400 in this embodiment has a drive control unit (not shown in the figure), which can control the light-emitting layer 1 to be in an extended state or a bent state. Further, when the drive control unit controls the light-emitting layer 1 to be in a bent state, it is not necessary to make the first light-emitting layer 11 in a state of being bent nearly 90 degrees as shown in Figure 8 Fig. b. It is only necessary to ensure that the first light-emitting layer 11 is bent so as not to block or only partially block the light path of the optical lens 32.

[0058] It should be noted that the relevant technical details mentioned in the first embodiment, the second embodiment, and the third embodiment are still valid in this embodiment. To avoid repetition, they will not be elaborated here. Correspondingly, the relevant technical details mentioned in this embodiment can also be applied to the first embodiment, the second embodiment, and the third embodiment.

[0059] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present invention, and in practical applications, various changes can be made in form and details without departing from the spirit and scope of the present invention.
