Since the folding screen has a folded state and an unfolded state. How to more effectively and more accurately control the display modes of the folding screen and the display screen used as the outer screen according to the state of the folding screen becomes a problem to be solved urgently.
The present disclosure proposes a terminal device, which may be a portable electronic device such as a smartphone, a tablet, a wearable device, and the like. The terminal equipment comprises two display screens, at least one display screen in the two display screens is a folding screen, the two display screens are arranged back to back when the folding screen is in an unfolded state, and the folding screen comprises two sub display screens. The terminal equipment further comprises a detection assembly, the detection assembly is arranged between the two display screens, and the detection assembly comprises a flexible movement portion and a detection unit. The flexible movement portion comprises a free end portion, when the folding screen is switched between the unfolding state and the folding state, the free end portion of the flexible movement portion moves relative to the preset position, and the detection unit is used for detecting the distance between the free end portion of the flexible movement portion and the preset position. The terminal equipment detects the distance information between the free end part and the preset position through the detection assembly in the starting or using process, judges the current state of the folding screen according to the distance information to determine the display mode of the display screen, controls the lighting and extinguishing of the folding screen according to the display mode of the display screen, and provides more comfortable use experience for a user. Meanwhile, according to the display mode of the display screen, the simultaneous lightening of a plurality of display screens can be avoided, the resource waste is reduced, and the service life of the display screen is prolonged.
As shown in fig. 1 and fig. 2, in an exemplary embodiment, a terminal device includes two display screens 1, at least one of the two display screens is a foldable screen 12, and the two display screens are arranged in a back-to-back manner when the foldable screen 12 is in an unfolded state. For example, the terminal device includes two display screens, the two display screens are respectively parallel to a plane formed by intersecting the X axis and the Y axis, and the two display screens are arranged back to back in the Z axis direction. Here, the back-to-back arrangement means that the light emitted from the two display panels is emitted in opposite directions when the two display panels are in the lit state. Of the two display screens, only one display screen can be a folding screen 12, the folding screen 12 is a flexible screen, and the other display screen is a flat screen 11; it is also possible that both displays are folding screens 12. In addition, when both displays are the folding screens 12, the sizes of both displays may be completely equal; when one of the two display screens is the folding screen 12 and the other is the flat screen 11, the area of the flat screen 11 is smaller than that of the folding screen 12, for example, the area of the flat screen 11 may be equal to half of the area of the folding screen 12, or may be smaller than half of the area of the folding screen 12. In this embodiment, the foldable screen 12 includes two sub-display screens, the two sub-display screens are a first sub-display screen 121 and a second sub-display screen 122, and the first sub-display screen 121 and the second sub-display screen 122 are rotatably connected by a hinge (not shown in the figure). When the other display screen is the folding screen 12, the two folding screens 12 may have the same size, and the two folding screens 12 are correspondingly disposed. When the other display screen is the flat screen 11, the flat screen 11 may be the same size as the first sub-display screen 121 or the second sub-display screen 122 and may be disposed corresponding to the first sub-display screen or the second sub-display screen.
In this embodiment, as still referring to fig. 1 and fig. 2, the terminal device further includes a detection component 2, and the detection component 2 is disposed between the two display screens along the Z-axis direction shown in fig. 1. In one example, a containing groove 13 is provided between the two display screens, and the detecting component 2 is disposed in the containing groove 13. The detection assembly 2 includes a flexible motion portion 21 and a detection unit 22. The flexible moving portion 21 includes a free end portion 211, and when the folding screen 12 is switched between the unfolded state and the folded state, the free end portion 211 of the flexible moving portion 21 can move relative to the preset position in the accommodating groove 13. The preset position may be an initial position of the free end portion 211 when the foldable screen 12 is in the unfolded state, and the preset position may also be an initial position of the free end portion 211 when the foldable screen 12 is in the folded state. The containing groove 13 can protect the detection assembly 2, and can also play a limiting role on the free end part 211 of the flexible moving part 21, so that the free end part 211 can do linear motion when moving, and when a user holds the terminal equipment, the free end part 211 cannot cause the motion path to deviate due to the inclination of the terminal equipment, and the accuracy of a detection result is ensured.
Besides the arrangement of the accommodating groove 13 for limiting the flexible moving part 21, other structures can be adopted for limiting the flexible moving part 21. In another example, the flexible moving portion 21 may be limited by a solid structure between the two display screens to prevent the flexible moving portion 21 from moving during the bending process of the folding screen 12.
In the present embodiment, the detection unit 22 is used for detecting the distance between the free end 211 of the flexible moving portion 21 and the preset position, the detection unit 22 may be a distance sensor or an infrared sensor, for example, and the signal of the detection unit 22 is transmitted to the processor. The preset position may further include a position where the detection unit 22 is located, and the detection unit 22 is configured to detect a distance when the free end 211 of the flexible moving portion 21 moves relative to the detection unit 22. For example, the detecting unit 22 may be an infrared sensor, the infrared sensor is disposed on the first sub-display 121, a transmitter of the infrared sensor transmits infrared rays, the infrared rays are reflected by the free end portion 211, a receiver of the infrared sensor receives the reflected infrared rays, and the infrared sensor measures a distance between the free end portion 211 and a preset position according to physical information related to the transmitted and received infrared rays. The distance information measured by the detection unit 22 is compared with the distance arrangement information in the processor, and the folding state of the folding screen at this time is confirmed. The detecting unit 22 may also be a radar sensor disposed on the first sub-display 121, the radar sensor emitting an electromagnetic wave, the electromagnetic wave being reflected by the free end portion 211, the radar sensor receiving the reflected electromagnetic wave, and measuring a distance between the free end portion 211 and a predetermined position according to physical information related to the emitted and received electromagnetic wave.
As shown in fig. 1 and 2, in another exemplary embodiment, the flexible moving portion 21 further includes a fixed end portion 212, the fixed end portion 212 is disposed corresponding to an area where one of the two sub-display panels is located, and the free end portion 211 is disposed corresponding to an area where the other of the two sub-display panels is located. For example, the free end portion 211 is fixedly disposed in an area where the first sub-display 121 is located, the fixed end portion 212 is disposed in an area where the second sub-display 122 is located, and two ends of the accommodating groove 13 are correspondingly disposed in the first sub-display 121 and the second sub-display 122, respectively. When the foldable screen 12 is switched from the unfolded state to the folded state, the position of the fixed end portion 212 relative to the second sub-display 122 remains unchanged, and since the shape of the folded region changes when the foldable screen is folded from the unfolded state to the folded state, the position of the free end portion 211 relative to the first sub-display 121 changes, that is, the distance between the free end portion 211 and the preset position changes. Of course, it can be understood that the free end portion 211 can also be disposed in the area where the second sub-display 122 is located, and the fixed end portion 212 is disposed in the area where the first sub-display 121 is located, and it can also be achieved that the detection unit 22 collects distance information generated by the free end portion 211 relative to a preset position, and the specific arrangement position of the free end portion 211 and the fixed end portion 212 is subject to an actual structural design. However, it should be clear that, no matter whether the fixed end portion 212 and the free end portion 211 are disposed in any one of the sub-display screens, the detection unit 22 and the free end portion 211 are both located on the same sub-display screen, the detection unit 22 is located on an extension line of the free end portion 211, and the flexible moving portion 21 and the detection unit 22 are used in cooperation, so that the detection result is accurate and effective.
In one example, the flexible moving portion 21 may be made of a flexible rubber material, which has high durability, low cost, long life, and is deformable with the folding or unfolding of the folding screen 12. The flexible movement portion 21 made of rubber is not easy to rub the accommodating groove 13, the first sub display screen and the second sub display screen in the movement process, and each structure cannot be damaged due to friction, so that the reliability is better.
As shown in fig. 1 and fig. 2, in this embodiment, the flexible moving portion 21 is long, the detecting unit 22 is disposed on an extension line of the flexible moving portion 21 in the length direction when the foldable screen 12 is in the unfolded state, and the detecting unit 22 and the free end portion 211 are located in the area where the first sub-display 121 is located at the same time. For example, when the foldable screen 12 is in the unfolded state, the free end 211 moves to the first limit position, when the foldable screen 12 is in the folded state, the free end 211 moves to the second limit position, and when the free end 211 is at the second limit position, the free end 211 is still located in the area where the first sub-display 121 is located, that is, when the free end 211 moves relative to the preset position, the free end 211 always keeps moving in the area where the first sub-display 121 is located, and keeps being located in the same interface with the detection unit 22, so that the detection unit 22 can accurately detect the distance between the free end 211 and the preset position.
