Description

Technical Field

[0001] This application belongs to the technical field of electronic products, and particularly relates to an electronic device. Background Art

[0002] With the improvement of user requirements, the performance of electronic devices has been increasingly optimized. Currently, electronic devices are developing towards a larger screen-to-body ratio. How to increase the screen-to-body ratio of electronic devices is the focus of current research and development by terminal manufacturers.

[0003] However, the front camera of an electronic device is usually arranged on one side of the display panel, which will occupy a relatively large board space of the electronic device and ultimately affect the screen-to-body ratio of the display panel of the electronic device. Based on this, the punched screen has become a relatively common and effective solution for current electronic devices. On the premise of not affecting the normal shooting of the camera arranged under the display panel, the opening size of the display panel will be as small as possible. It is extremely easy for the ink edge to block the front camera's viewing area at the opening, resulting in problems such as photographing shadows and stray light, and the viewing area cannot be adjusted according to the actual situation. Summary of the Invention

[0004] This application aims to provide an electronic device, which at least solves the problems that the ink edge at the opening of the existing display panel is extremely easy to block the front camera's viewing area, resulting in photographing shadows and stray light.

[0008] The light-blocking part includes a light-shielding layer, an electrochromic layer, and a control electrode layer arranged on at least one side of the electrochromic layer.

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0021] Next, in conjunction with Figures 1 to 3 An electronic device according to an embodiment of the present application will be described. The electronic device may be a smart phone, a game console, a tablet computer, an e-book reader or a wearable device. Of course, the electronic device may also be other devices, and the embodiments of the present invention do not limit this.

[0022] Taking a mobile phone as an example, the electronic device includes: a display panel 100 and a camera 200 disposed on one side of the display panel 100. The display panel 100 is used to cooperate with the electronic device for display, and the display panel 100 may adopt a flexible screen or a rigid screen. The camera 200 is disposed opposite to the display panel 100 and is disposed on one side of the display panel 100.

[0023] In this embodiment, the display panel 100 includes: a first part 101, a second part 102 and a light-blocking part 103. The first part 101 faces the camera 200 directly, and the light-blocking part 103 is disposed between the first part 101 and the second part 102. The light-blocking part 103 includes a light-shielding layer 1031, an electrochromic layer 1032 and a control electrode layer 300 disposed on at least one side of the electrochromic layer 1032. The electrochromic layer 1032 is located on the side of the light-blocking part 103 close to the first part 101, and the light-shielding layer 1031 is located on the side of the light-blocking part 103 close to the second part 102. The control electrode layer 300 is used to control the electrochromic layer 1032 to switch between a light-shielding state and a light-transmitting state.

[0024] When the electrochromic layer 1032 is in the light-shielding state, the light-shielding layer 1031 and the electrochromic layer 1032 simultaneously block between the first part 101 and the second part 102. When the electrochromic layer 1032 is in the light-transmitting state, only the light-shielding layer 1031 blocks between the first part 101 and the second part 102. That is, when the electrochromic layer 1032 is in the light-transmitting state, the viewing area can be increased.

[0025] Specifically, in the initial state, the control electrode layer 300 receives a first control signal, and the control electrode layer 300 inputs a power-off signal to the electrochromic layer 1032. The electrochromic layer 1032 switches to the light-shielding state, and the light-shielding layer 1031 and the electrochromic layer 1032 are jointly used for blocking, increasing the blocked part between the first part 101 and the second part 102.

[0026] After the control electrode layer 300 receives a second control signal, the control electrode layer 300 inputs a power-on signal to the electrochromic layer 1032. The electrochromic layer 1032 switches to the light-transmitting state. At this time, the electrochromic layer 1032 can transmit light, and only the light-shielding layer 1031 blocks between the first part 101 and the second part 102. Therefore, by controlling the control electrode layer 300, the viewing area of the camera 200 can be controlled and adjusted, avoiding problems such as photographing shadows and stray light caused by the ink edge blocking the viewing area of the front camera 200.

[0027] It should be noted that by adjusting the power of the control electrode layer 300, some of the electrochromic layer 1032 can also be controlled to be in the light-shielding state, and some of the electrochromic layer 1032 can be controlled to be in the light-transmitting state, so that the viewing area can be freely adjusted.

[0028] In the embodiment of the present application, the display panel includes a first part, a second part, and a light-blocking part. By setting a light-blocking part between the first part and the second part, the light-blocking part includes a light-shielding layer, an electrochromic layer, and a control electrode layer provided on at least one side of the electrochromic layer. The electrochromic layer is located on the side of the light-blocking part close to the first part, and the light-shielding layer is located on the side of the light-blocking part close to the second part. The control electrode layer is used to control the electrochromic layer to switch between the light-shielding state and the light-transmitting state. Thus, by controlling the control electrode layer, the viewing area of the camera is adjusted, avoiding problems such as photographing shadows and stray light caused by the ink edge blocking the viewing area of the front camera.

[0029] In one example, as Figures 1 to 3 shown, the first part 101 functions as a light-transmitting area. The first part 101 is disposed opposite to the camera 200. The light-blocking part 103 is disposed around the first part 101, and the light-blocking part 103 isolates the first part 101 and the second part 102 from each other.

[0030] In one embodiment, as Figures 1 to 3 shown, the light-blocking part 103 includes a light-shielding layer 1031, an electrochromic layer 1032, and a control electrode layer 300 disposed on at least one side of the electrochromic layer 1032. The light-shielding layer 1031 is arranged in a ring shape, the electrochromic layer 1032 is arranged at the edge of the inner circle of the light-shielding layer 1031, the first part 101 is arranged in the inner circle of the electrochromic layer 1032, and correspondingly, the control electrode layer 300 is also arranged in a ring shape.

[0031] In this embodiment, after the control electrode layer 300 inputs a power-off signal to the electrochromic layer 1032, the electrochromic layer 1032 switches to a light-blocking state, and the light-shielding layer 1031 and the electrochromic layer 1032 are jointly used for shielding. The electrochromic layer 1032 cooperates with the light-shielding layer 1031 to increase the shielding part of the inner ring, and the camera 200 can only take pictures through the first part 101. After the control electrode layer 300 inputs a power-on signal to the electrochromic layer 1032, the electrochromic layer 1032 switches to a light-transmitting state, the electrochromic layer 1032 and the first part 101 can transmit light at this time, and the shielding part of the inner circle of the light-shielding layer 1031 is reduced, thereby increasing the viewing area.

[0032] In some embodiments, the electrochromic layer 1032 is annular and the electrochromic layer 1032 is arranged around the first part 101.

[0033] In other embodiments, the electrochromic layer includes a first color-changing part and a second color-changing part that are separated from each other. One side of the electronic device is bent around the folding axis, and the first color-changing part and the second color-changing part are respectively arranged on opposite sides of the first part 101 along a direction perpendicular to the folding axis; thereby improving the vision occlusion caused by the folding of the electronic device.

[0034] In another embodiment, as Figures 1 to 3 shown, the light-blocking part 103 includes a light-shielding layer 1031, an electrochromic layer 1032, and a control electrode layer 300 disposed on at least one side of the electrochromic layer 1032. Generally, two light-shielding layers 1031 are provided. The two light-shielding layers 1031 are arranged at intervals, and electrochromic layers 1032 are provided on one side of the two light-shielding layers 1031 close to each other. The first part 101 is arranged between the electrochromic layers 1032.

[0035] In this embodiment, after the control electrode layer 300 inputs a power-off signal to the electrochromic layer 1032, the electrochromic layer 1032 switches to the light-shielding state. The light-shielding layer 1031 and the electrochromic layer 1032 are jointly used for shielding. The electrochromic layer 1032 cooperates with the two light-shielding layers 1031 to increase the shielding part, and the camera 200 can only take pictures through the first part 101. After the control electrode layer 300 inputs a power-on signal to the electrochromic layer 1032, the electrochromic layer 1032 switches to the light-transmitting state. At this time, the electrochromic layer 1032 and the first part 101 can transmit light, and the shielding part between the two light-shielding layers 1031 is reduced, thereby increasing the viewing area.

[0036] In the existing folding technical solution, at the hole in the active area (HIAA) of the display area, it is impossible to avoid the risk of visual field occlusion caused by factors such as the bending and sliding amount between the stacked layers of the folding product module, the sliding amount, and the material fitting tolerance. As the number of bends of the folding product increases, the sliding amount between the stacked layers of the module will also increase and the material has fatigue problems, seriously affecting the ultimate experience of consumers.

[0037] During the bending process of the folding screen, the stacked layers of the module at the hole position in the display area slide, which causes a positional deviation between the cover plate ink and the front camera. Moreover, the folding product undergoes hundreds of thousands of bends in the hands of consumers, and the material will also have bending fatigue, and the recovery performance will be worse. This will cause the distance from the intersection of the light and the cover plate to the ink to be reduced to a negative value. The folding sliding displacement will cause the distance of the product to be directly blocked by the ink and produce a shadow, seriously affecting the camera shooting effect of the user.

[0038] To solve the above problems, in one example, as Figures 1 to 4 shown, the electronic device has a folded state and an unfolded state.

[0039] When the electronic device is in the folded state, as Figure 2 and Figure 3 shown, since the camera 200 will slide relative to the display panel 100, causing an offset of the camera 200 from the first part 101, thus affecting the viewing area of the camera 200. At this time, the control electrode layer 300 inputs a power-on signal to the electrochromic layer 1032, and the electrochromic layer 1032 switches to the light-transmitting state. At this time, the electrochromic layer 1032 can transmit light, and only the light-shielding layer 1031 shields between the first part 101 and the second part 102, increasing the viewing area, thereby reducing the influence of the offset on the visual field.

[0040] When the electronic device is in the unfolded state, as Figure 1As shown, at this time, the camera 200 is facing the first part 101 directly. Since there is no need to increase the field of view, the control electrode layer 300 inputs a power-off signal to the electrochromic layer 1032. The electrochromic layer 1032 switches to the light-shielding state. The light-shielding layer 1031 and the electrochromic layer 1032 together are used for shielding, increasing the shielded part between the first part 101 and the second part 102.

[0041] In another embodiment, the electronic device has a folded state and an unfolded state. When the electronic device is in the unfolded state, the shooting end of the camera 200 is located at the center of the first part 101. When the electronic device is in the folded state, the camera 200 is offset to one side of the first part 101. That is, during the process of switching between the unfolded state and the folded state, the camera 200 slides relative to the display panel 100. Based on the different sliding amounts during the bending process, the camera 200 also slides relative to the display panel 100.

[0042] In this embodiment, the control electrode layer 300 always inputs an electric field signal externally to form a non-uniform electric field in the horizontal direction. The electric field lines are emitted from the positive electrode and received by the negative electrode, and the area between the positive and negative electrodes will be affected by the electric field. That is, when the control electrode layer 300 is aligned with the electrochromic layer 1032, the electrochromic layer 1032 can switch its state.

[0043] Specifically, in the initial state (unfolded state), as Figure 1 shown, the camera 200 is facing the center of the first part 101 directly. The control electrode layer 300 is disposed opposite to other components in the light-shielding layer 1031 or the display panel 100. That is, the control electrode layer 300 is misaligned with the electrochromic layer 1032. The electrochromic layer 1032 is not in the electromagnetic field region and is not affected by the electric field. At this time, the electrochromic layer 1032 is in the light-shielding state, and light cannot pass through, thus acting as a light-shielding ink. The light-shielding layer 1031 and the electrochromic layer 1032 together are used for shielding.

[0044] After the electronic device switches to the folded state, as Figure 2 and Figure 3 shown, if it is found that the camera 200 is offset to one side of the first part 101, the control electrode layer 300 is disposed opposite to at least a part of the electrochromic layer 1032. At least a part of the electrochromic layer 1032 opposite to the control electrode layer 300 is in the electromagnetic field region and is affected by the electromagnetic field. At this time, at least a corresponding part of the electrochromic layer 1032 switches to the light-transmitting state, and light can pass through the electrochromic layer 1032. Only the light-shielding layer 1031 shields the light-transmitting part, so that the field of view of the camera 200 can be controlled and adjusted.

[0045] In addition, when the electronic device is folded in other directions, the camera 200 can also move in other directions. By disposing the electrochromic layer 1032 at the edge of the inner circle of the light-shielding layer 1031, no matter which direction the camera 200 moves, the visual field area of the camera 200 can be controlled and adjusted. Through the action of an electric field on the electrochromic layer 1032, the electrochromic layer 1032 becomes transparent, and light can pass through completely, avoiding the problem of light occlusion caused by the slip and misalignment during the bending process. In addition, in the non-bent state, the electrochromic layer 1032 is not affected by the electric field, and the electrochromic layer 1032 returns to its previous black state and functions as an ink.

[0046] In one example, the display panel 100 includes a substrate, a thin-film transistor layer, a light-emitting layer 1001, and a packaging layer 1002 that are sequentially stacked on one side of the substrate. The camera 200 is disposed on the side of the substrate away from the thin-film transistor layer, and the light-shielding layer 1031 is disposed in the packaging layer 1002.

[0047] According to requirements, the position of the electrochromic layer 1032 can also be adjusted. The electrochromic layer 1032 is disposed in the light-emitting layer 1001 or the packaging layer 1002.

[0048] When the electrochromic layer 1032 and the light-shielding layer 1031 are both disposed in the packaging layer 1002, the electrochromic layer 1032 and the light-shielding layer 1031 are disposed adjacent to each other, or the electrochromic layer 1032 and the light-shielding layer 1031 are spaced apart from each other. To ensure the continuity of the visual field area, it is necessary to ensure that the orthographic projection of the light-shielding layer 1031 on the substrate is connected to the orthographic projection of the electrochromic layer 1032 on the substrate. Thus, in the case where the electrochromic layer 1032 is in the light-shielding state, the light-shielding layer 1031 and the electrochromic layer 1032 continuously block the edge of the visual field area of the camera 200, ensuring the continuity of the visual field area.

[0049] To facilitate the control of the state switching of the electrochromic layer 1032, the electrochromic layer 1032 can also be disposed in the light-emitting layer 1001, and the light-shielding layer 1031 is disposed in the packaging layer 1002. At this time, to ensure the continuity of the visual field area, it is also necessary to ensure that the orthographic projection of the light-shielding layer 1031 on the substrate is connected to the orthographic projection of the electrochromic layer 1032 on the substrate. Thus, in the case where the electrochromic layer 1032 is in the light-shielding state, the light-shielding layer 1031 and the electrochromic layer 1032 continuously block the edge of the visual field area of the camera 200, ensuring the continuity of the visual field area and avoiding problems such as photographing shadows and stray light caused by the ink edge blocking the visual field area of the front camera.

[0050] It should be noted that a driving electrode layer 1003 for driving the light-emitting layer 1001 to emit light is also provided in the light-emitting layer 1001, and the driving electrode layer 1003 is electrically connected to the thin-film transistor layer. The control electrode layer 300 is provided on the same layer as the driving electrode layer 1003, thereby facilitating the control of the driving electrode layer 1003 and the control electrode layer 300.

[0051] In one embodiment, the encapsulation layer 1002 includes: a cover plate 10021 and a support layer 10022. The cover plate 10021 and the support layer 10022 are connected by an optical adhesive, and the light-shielding layer 1031 and the electrochromic layer 1032 are both provided between the cover plate 10021 and the support layer 10022. That is, the light-shielding layer 1031 and the electrochromic layer 1032 can be provided in the optical adhesive between the cover plate 10021 and the support layer 10022, or grooves for placing the light-shielding layer 1031 and the electrochromic layer 1032 can be provided on the light-shielding layer 1031 and the electrochromic layer 1032.

[0052] In the case where the electrochromic layer 1032 is in the light-shielding state, the light-shielding layer 1031 and the electrochromic layer 1032 block a partial visual field area of the camera 200 between the cover plate 10021 and the support layer 10022. In the case where the electrochromic layer 1032 is in the light-transmitting state, only the light-shielding layer 1031 blocks a partial visual field area of the camera 200 between the cover plate 10021 and the support layer 10022, thereby increasing the range of the visual field area.

[0053] Based on the above embodiments, in one embodiment, as Figures 1 to 4 shown, a shooting hole 1000 is provided on one side of the display panel 100, and the shooting hole 1000 is opposite to the first part 101. The electronic device includes: a frame body 400 and a stage 500.

[0054] Among them, the frame body 400 is provided with a mounting hole coaxially arranged with the shooting hole 1000, and one end of the camera 200 passes through the mounting hole and is arranged in the shooting hole 1000. The stage 500 is arranged on the side of the frame body 400 away from the display panel 100, and the other end of the camera 200 is arranged on the stage 500.

[0055] In this embodiment, the bottom end of the camera 200 is connected to the stage 500 by a pressure-sensitive adhesive. A front camera bracket 600 and a foam 700 are also provided between the camera 200 and the frame body 400, and the circumferential edge of the camera 200 abuts against the frame body 400 through the front camera bracket 600 and the foam 700. The display panel 100 is integrally arranged on the outside of the frame body 400 through an adhesive layer and a steel sheet 800 in sequence.

[0056] In the initial state, as Figure 1As shown, the camera 200 faces the shooting hole 1000 directly, and the control electrode layer 300 is disposed opposite to the light-shielding layer 1031 or other components in the display panel 100, that is, the control electrode layer 300 is misaligned with the electrochromic layer 1032. The electrochromic layer 1032 is not in the electromagnetic field region and is not affected by the electric field. At this time, the electrochromic layer 1032 is in the light-shielding state, and light cannot pass through, thus acting as a light-shielding ink. The light-shielding layer 1031 and the electrochromic layer 1032 are jointly used for shielding. After the electronic device is switched to the folded state, such as Figure 2 and Figure 3 As shown, the camera 200 is offset to one side of the shooting hole 1000. The control electrode layer 300 is disposed opposite to at least a part of the electrochromic layer 1032. At least a part of the electrochromic layer 1032 opposite to the control electrode layer 300 is in the electromagnetic field region and is affected by the electromagnetic field. At this time, at least a corresponding part of the electrochromic layer 1032 is switched to the light-transmitting state, and light can pass through the electrochromic layer 1032. Only the light-shielding layer 1031 shields in the light-transmitting part, and the viewing area of the camera 200 is controlled and adjusted.

[0057] Based on the above embodiments, in one embodiment, as Figures 1 to 4 shown, the light-shielding layer 1031 includes: a light-shielding ink layer, such as a black ink layer. The electrochromic layer 1032 includes liquid crystal, and an electrochromic material coated with liquid crystal polymer. The polymer electrochromic material deflects the liquid crystal under the action of an electric field, that is, the liquid crystal molecules can shield or transmit light according to the drive of the control electrode layer 300. The control electrode layer 300 includes a first electrode plate and a second electrode plate; both the first electrode plate and the second electrode plate are disposed in the display panel 100. The first electrode plate applies positive electricity, and the second electrode plate applies negative electricity, which is the receiving end position of the electric field line. Both the first electrode plate and the second electrode plate are made of metal plates, and a non-uniform electric field in the horizontal direction is formed between the two metal plates. The electric field lines are emitted from the positive electrode and received by the negative electrode, and the region between the positive and negative electrodes (including the vertical direction) will be affected by the electric field, as Figure 2 shown by the dashed box in. When the electronic device is in the folded state, voltages are respectively applied to the first electrode plate and the second electrode plate to switch the electrochromic layer 1032 between the light-shielding state and the light-transmitting state.

[0058] According to needs, the positions of the first electrode plate and the second electrode plate can be adjusted to adjust the direction of the electric field, so as to adjust the state of the electrochromic layer 1032.

[0059] In this embodiment, both the first electrode plate and the second electrode plate adopt an annular structure. The first electrode plate is arranged on the outer circle, and the second electrode plate is arranged on the inner circle of the first electrode plate. When a magnetic field is formed by the first electrode plate and the second electrode plate acting on the electrochromic layer 1032, the electrochromic layer 1032 can be switched between the light-shielding state and the light-transmitting state.

[0060] In a specific embodiment, as Figures 1 to 4 shown, the display panel 100 includes: a substrate, and a thin-film transistor layer, a light-emitting layer 1001, a polarizer, a support layer 10022, and a cover plate 10021 that are sequentially stacked on one side of the substrate. The camera 200 is disposed on the side of the substrate away from the thin-film transistor layer, and the light-shielding layer 1031 is disposed in the encapsulation layer 1002. Both the light-shielding layer 1031 and the electrochromic layer 1032 are disposed between the support layer 10022 and the cover plate 10021, and the control electrode layer 300 is disposed in the light-emitting layer 1001. A shooting hole 1000 is provided on one side of the display panel 100, and the shooting hole 1000 penetrates through the substrate, the thin-film transistor layer, the light-emitting layer 1001, and the polarizer, and the shooting hole 1000 faces the first part 101.

[0061] In the case where the electronic device is in the unfolded state, as Figure 1 shown, the shooting end of the camera 200 is coaxially disposed with the shooting hole 1000. The camera 200 faces the shooting hole 1000, and the control electrode layer 300 is disposed opposite to the light-shielding layer 1031 or other components in the display panel 100, that is, the control electrode layer 300 is disposed offset from the electrochromic layer 1032, and the electrochromic layer 1032 is not in the electromagnetic field region and is not affected by the electric field. At this time, the electrochromic layer 1032 is in the light-shielding state, and light cannot pass through, thus acting as a light-shielding ink. The light-shielding layer 1031 and the electrochromic layer 1032 are jointly used for shielding.

[0062] In the case where the electronic device is in the folded state, as Figure 2 and Figure 3 shown, the camera 200 is offset to one side of the shooting hole 1000. The control electrode layer 300 is disposed opposite to at least a part of the electrochromic layer 1032, and at least a part of the electrochromic layer 1032 opposite to the control electrode layer 300 is in the electromagnetic field region and is affected by the electromagnetic field. At this time, at least a part of the corresponding electrochromic layer 1032 is switched to the light-transmitting state, and light can pass through the electrochromic layer 1032, and only the light-shielding layer 1031 shields in the light-transmitting part, and the viewing area of the camera 200 is controlled and adjusted.
