[0016] To make the purpose, technical solution, and advantages of the present application clearer, the technical solution of the present application is described below with reference to specific embodiments and corresponding drawings. The described embodiments are only some embodiments of the present application, not all. Any other embodiments obtained by a person skilled in the art through the embodiments of the present application without creative effort will fall within the scope of protection of the present application.

[0017] Hereinafter, the technical solutions disclosed in each embodiment of the present application will be explained in detail through specific embodiments with reference to the drawings.

[0018] As illustrated in FIGS. 1 to 6, an embodiment of the present application discloses an electronic device comprising a case (100), a display screen (200), and a deformation driving unit (300). The case (100) provides protection for other components of the electronic device to prevent collision damage to these components.

[0019] A display screen (200) is installed in a case (100) and includes a first area (210) and a second area (220), wherein the first area (210) is a first planar area and the second area (220) is interconnected with the first area (210) and is located at the edge of the display screen (200).

[0020] The deformation drive unit (300) is connected to the inner side of the second region (220), and the deformation drive unit (300) drives the second region (220) to switch between an unfolded state and a curved state through deformation. There are various types of deformation drive units (300), such as electric deformation drive units, electric field deformation drive units, drive motors, etc., and the embodiments of the present application do not impose specific limitations on this. The second region (220) can switch between an unfolded state and a curved state through the deformation drive unit (300). The display range of the display screen (200) differs depending on the state of the second region (220). When the second region (220) is in an unfolded state, the second region (220) is a second planar region, and the second planar region and the first region are located within the same plane. At this time, the first area (210) and the second area (220) are located on the same plane to form a display screen (200) with a large display area, which is advantageous for games requiring screen manipulation, can provide good visual effects to the user, and can enhance the user's game experience and visual perception. When the second area (220) is in a curved state, the second area (220) is curved relative to the first area (210). At this time, the second area (220) in the curved state is interconnected with the first flat area to form the shape of a waterfall screen in appearance. This allows for providing the user with a visual impact of a borderless display screen and has a good grip.

[0021] Additionally, the electronic device further includes a support means (400). The support means (400) supports the deformation drive unit (300) so that the structure of the display screen (200) is stabilized when the deformation drive unit (300) drives the second region (220) to switch between an unfolded state and a curved state through deformation. The support means (400) includes a flat support body (410) and a movement drive unit (420). The flat support body (410) is installed to move relative to the second region (220), and its state changes as the second region (220) switches between an unfolded state and a curved state. The movement drive unit (420) is interconnected with the flat support body (410), is installed within the case (100), and drives the flat support body (410) to switch between a supported state and an avoidance state. When the flat support body (410) is in a supported state, the flat support body (410) is supported on the inner side of the deformation drive unit (300). At this time, the flat support body (410) supports the deformation drive unit (300), the second region (220) is in an unfolded state, and the flat support body (410) can perform a supporting role to ensure it remains in a good flat state. When the flat support body (410) is in an avoidance state, the flat support body (410) avoids the second region (220) which is in a curved state through the action of the movement drive unit (420).

[0022] According to the electronic device disclosed in the embodiment of the present application, by improving the structure of the electronic device of the background technology, the support means (400) supports the deformation drive unit (300), and the deformation drive unit (300) is deformed according to different demands of the user so that the second region (220) is switched between an unfolded state and a curved state, and when the user demands a good visual experience and a game experience, the second region (220) is in an unfolded state by the action of the deformation drive unit (300), and the flat support body (410) of the support means (400) is supported on the inside of the deformation drive unit (300) by the action of the movement drive unit (420) and is in a supported state, and at this time, the first flat region and the second region (220) are located on the same plane so as to satisfy the user's use for scenarios such as a game experience and hologram viewing; When a user requests the daily mode of the electronic device, the second region (220) is in a curved state, and the flat support body (410) of the support means (400) avoids the second region (220) in a curved state by the action of the movement drive unit (420) to form a waterfall-shaped display screen, thereby providing the user with a good grip. From this, it can be seen that the electronic device according to the embodiment of the present application allows the display screen to switch between two different screen display modes, thereby solving the problem of poor user experience caused by the curved screen design of conventional electronic devices.

[0023] In one possible embodiment, the electronic device further includes a folding means (500) that seals and connects the second region (220) and the case (100). When the second region (220) is in an unfolded state, the folding means (500) is in an unfolded state as the second region (220) moves, which can further stabilize the structure of the display screen (200) and avoid a situation where the display screen (200) lacks rigidity, while effectively sealing the gap formed between the second region (220) and the case (100) due to the unfolding. When the second region (220) is in a curved state, the folding means (500) is in a folded state, and the folding means (500) can be folded and stored inside the electronic device.

[0024] In other possible embodiments, the electronic device may further include elastic connecting means. The elastic connecting means may be of various types, such as springs, elastic pieces, etc., but the embodiments of the present application are not specifically limited thereto. The elastic connecting means seals the second region (220) and the case (100). When the second region (220) is in an unfolded state, the elastic connecting means is in an extended state, and the elastic connecting means in the extended state can form a large covering area and can effectively seal the gap formed between the second region (220) and the case (100) due to unfolding. Accordingly, the internal structure of the electronic device can be avoided from being exposed, and good dustproof and waterproof functions can be achieved. When the second region (220) is in a curved state, the elastic connecting means is in a shortened state, so that it can adapt well to changes in the distance between the second region (220) and the case (100).

[0025] In an additional technical solution, the deformation driving unit (300) may include a base unit (310) and a deformation main body unit (320). The deformation main body unit (320) is interconnected with the base unit (310), and the base unit (310) is fixed to the inner surface of the first planar area so that no deformation occurs. The deformation main body unit (320) is attached to the inner surface of the second area (220). The design attached to the inner surface of the display screen (200) can achieve a concealed design effect and increase the space utilization rate of the electronic device. The deformation main body unit (320) drives the second area (220) to switch between an unfolded state and a curved state through deformation, so that the display screen (200) of the electronic device implements different screen display modes and enriches the user's choice of use.

[0026] Additionally, there are various types of deformation driving units (300). In one possible embodiment, the deformation driving unit (300) may be an electric field deformation structure. The deformation driving unit (300) is deformed under the action of an electric field, thereby driving the second region (220) to switch between an unfolded state and a curved state, and further enabling the display screen (200) of the electronic device to switch between two different modes, thereby satisfying various user needs.

[0027] Of course, the deformation drive unit (300) may be an electro-deformable structure, and the electronic device further includes a flexible electrical connection member (600). A first end of the flexible electrical connection member (600) is electrically connected to the electro-deformable structure, and a second end of the flexible electrical connection member (600) is electrically connected to a power source (700) within the electronic device. The power source (700) can provide power to the electro-deformable structure through the flexible electrical connection member (600), allowing the electro-deformable structure to deform after being conductive. The flexible electrical connection member (600) may be of various types, such as a flexible cable or a flexible circuit board. If the flexible electrical connection member (600) is a flexible circuit board, the power source (700) can be integrated into the flexible circuit board, and can provide power to the electro-deformable structure and control the operating status of the electro-deformable structure through the flexible circuit board.

[0028] In another possible embodiment, the deformation drive unit (300) may be an electric deformation structure. In the process of the deformation drive unit (300) driving the second region (220) to transition from a curved state to an unfolded state through deformation, the electric deformation structure is subjected to a first voltage and a second voltage in sequence, and the second voltage is greater than the first voltage. When the first voltage is applied to the electric deformation structure, the electric deformation structure is driven so that the second region (220) is in a curved state, and when the second voltage (greater than the first voltage) is applied to the electric deformation structure, the electric deformation structure is deformed so that the second region (220) is in an unfolded state. According to this method, by avoiding deformation using a drive motor of a mechanical structure, internal space of the electronic device can be saved and space utilization of the electronic device can be provided.

[0029] In an embodiment of the present application, the case (100) may include a back cover (110) comprising a flat portion (1101) and a curved portion (1102) interconnected with the flat portion (1101). When the second region (220) is in a curved state, the curved portion (1102) is connected to the second region (220) to improve the integrity of the exterior of the electronic device. In an additional technical solution, the tangent of the connection portion between the curved portion (1102) and the second region (220) is the same, thereby improving the grip performance of the electronic device.

[0030] In an electronic device according to an embodiment of the present application, a flat support body (410) can be in rolling contact with an inner surface of a display screen (200) through at least two rotation axes (411), thereby reducing friction due to relative movement between the flat support body (410) and the display screen (200).

[0031] The movement drive unit (420) includes a first deformation structure (421) and a second deformation structure (422). A first end of the first deformation structure (421) is interconnected with the case (100), and a second end of the first deformation structure (421) is interconnected with the second deformation structure (422). The first deformation structure (421) drives the second deformation structure (422) to move toward or away from the edge of the display screen (200), thereby enabling support by approaching the edge of the display screen (200) or avoidance by moving away from the edge of the display screen (200). The second deformation structure (422) is movably installed within the case (100), and the second deformation structure (422) is supported on the inside of the deformation drive unit (300). The second deformation structure (422) can move in a direction approaching or moving away from the deformation drive unit (300), thereby enabling support or avoidance of the second region (220) through the deformation drive unit (300) and adaptive support for deformation of the second region (220).

[0032] There are multiple second deformation structures (422). Multiple second deformation structures (422) are formed integrally and can be driven by the first deformation structure (421), so that the multiple second deformation structures (422) can move in a direction approaching or moving away from the deformation driving unit (300).

[0033] The first deformation structure (421) and the second deformation structure (422) are of various types, and may be electric deformation structures or electric field deformation structures, and the embodiments of the present application are not specifically limited thereto. When both the first deformation structure (421) and the second deformation structure (421) are electric deformation structures, the expansion and contraction of both can be realized by applying a fixed voltage to both. In a specific operation process, when a fixed voltage is applied to the second deformation structure (422), the second deformation structure (422) can be pushed to move the second deformation structure (422) to approach the edge of the display screen (200) by applying a fixed voltage to the first deformation structure (421) after contacting the flat plate support body (410). At this time, the second deformation structure (422) approaches the deformation drive unit (300) so that the flat support body (410) is in a supported state, and the second region (220) is in an unfolded state under the action of the deformation drive unit (300). During the avoidance process, by adjusting the direction of the voltage, the first deformation structure (421) and the second deformation structure (422) can be moved in opposite directions.

[0034] Based on the electronic device described above, the present application is,

[0037] When the input is the first input, the deformation drive unit (300) is controlled to drive the second area (220) so that it is in an unfolded state.

[0038] When the input is the second input, the deformation drive unit (300) is controlled to drive the second region (220) so that it is in a curved state.

[0039] By controlling the deformation of the deformation drive unit (300) to drive the second area (220) to switch between an unfolded state and a curved state, the user can select different display screen modes, thereby resolving issues such as the viewing angle of the curved screen, the operation problem of the edge screen in games, and touch error problems. Additionally, since the second area (220) can be unfolded to provide a good display, the problem of the edge of the screen reflecting light due to the curve and affecting the display can be avoided, and the advantages of the curved screen's visual impact and grip can be maintained, allowing the user to have a good user experience.

[0040] Based on the electronic device and the control method described above, the present application comprises:

[0041] A receiving module that receives input, and if the received inputs are different, transmits the input to a different control module, and controls the transformation drive unit (300) to perform different operations by the control module;

[0042] A first control module that, when the input is the first input, controls the deformation drive unit (300) to drive the second area (220) so that it is in the unfolded state;

[0043] A control device for an electronic device is disclosed, comprising: a second control module that controls a deformation drive unit (300) to drive the second region (220) so that it is in the curved state when the input is a second input.

[0044] Through this, the second area (220) can be switched between an unfolded state and a curved state, and the effect of different screen displays can be realized.
