The terminal device with the folding screen in the related art is convenient for a user to perform operations such as time checking and incoming call checking, generally, besides the folding screen, a display screen capable of being used as an outer screen is additionally arranged, and when the folding screen is in a folding state, the user can perform related operations on the outer screen. 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, an elastic portion and a detection unit, wherein the elastic portion is connected with the flexible movement portion. The flexible movement portion comprises a free end portion, the free end portion is connected with the elastic portion, and when the folding screen is switched between the unfolding state and the folding state, the free end portion of the flexible movement portion drives the elastic portion to generate elastic deformation. And the detection unit is used for detecting the pressure information of the elastic part. The terminal equipment detects the pressure information of the elastic part through the detection assembly in the starting or using process, judges the current state of the folding screen according to the pressure information of the elastic part so as 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 users. Meanwhile, according to the state of the folding screen, the display mode of the display screen is adjusted, so that the situation that a plurality of display screens are lightened simultaneously can be avoided, the resource waste is reduced, and the service life of the display screen is prolonged.
As shown in fig. 1 and 2, in an exemplary embodiment, a terminal device includes two display screens, 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 the present 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. 2. 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 movement portion 21, an elastic portion 23 connected to the flexible movement portion 21, and a detection unit 22. The flexible moving portion 21 includes a free end portion 211, the free end portion 211 is fixedly connected to one end of the elastic portion 23, and the other end of the elastic portion 23 is a fixed end. For example, the other end of the elastic portion 23 is fixedly connected to the detection unit 22, the compressive stress or tensile stress of the elastic portion 23 directly acts on the detection unit 22, and the detection unit 22 directly acquires the pressure information of the elastic portion 23. For another example, the other end of the elastic portion 23 is directly fixed to the wall of the accommodating groove 13, a strain gauge is attached to the side surface of the elastic portion 23, and the detection unit 22 acquires pressure information of the elastic portion 23 through the strain gauge. The elastic portion 23 may be, for example, a rubber spring or a coil spring. When the folding screen 12 is switched between the unfolding state and the folding state, the free end portion 211 of the flexible moving portion 21 can drive the elastic portion 23 to generate elastic deformation in the accommodating groove 13. 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, a hardware structure between the two display screens may be used to limit the position of the flexible motion portion 21, so as to prevent the flexible motion portion 21 from moving during the bending process of the folding screen 12. Of course, it is understood that the elastic portion 23 may also limit the position of the free end 221 of the flexible moving portion 21, so that the free end 221 moves along the stretching or compressing direction, and therefore, the accommodating groove may not be provided.
In the present embodiment, the detection unit 22 is used for detecting the pressure information of the elastic portion 23, and the detection unit 22 may be, for example, a pressure sensor, a piezoresistive sensor, a strain gauge sensor, a piezoelectric sensor, or the like. The pressure sensor senses the pressure signal of the elastic part 23 and transmits the pressure signal to the processor, so that the processor of the mobile terminal controls the display mode of the display screen according to the pressure information. Alternatively, the strain gauge sensor acquires a pressure signal of the elastic portion 23 through a strain gauge provided on the elastic portion 23, and transmits the pressure signal to the sensor. The pressure information includes a pressure type and a pressure value, the pressure type includes a tensile stress or a compressive stress applied to the elastic portion 23, so as to determine a state of the folding screen 12 according to the pressure type and the pressure value, and further control a display mode of the display screen. For example, when the pressure information is a tensile stress of 10Pa, the folding screen 12 is in a folded state, and the folding screen 12 is controlled to be turned off. For another example, when the pressure information is a pressure stress of 15Pa, the folding screen 12 is in the unfolded state, and the folding screen 12 is controlled to be lit. In one example, the elastic portion 23 includes a spring, and when the foldable screen 12 is in the fully unfolded state, that is, the included angle between the two sub-display screens is 180 °, the spring is in the natural relaxation state, and when the foldable screen 12 changes from the fully unfolded state to the folded state, the spring is subjected to a tensile stress, and at this time, the state of the foldable screen 12 is determined only according to the value of the pressure without considering the type of the pressure. For example, when the pressure value is 5N, the folding screen 12 is in the unfolded state, and the folding screen 12 is controlled to be lit. For another example, when the pressure value is 10N, the folding screen 12 is in a folded state, and the folding screen 12 is controlled to be turned off.
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 when the foldable screen 12 is folded from the unfolded state to the folded state, the shape of the folded region changes, so that the position of the free end portion 211 relative to the first sub-display 121 changes, that is, the free end portion 211 drives the elastic portion 23 to move, so that the elastic portion 23 generates elastic deformation, and the detection unit 22 detects pressure information of the elastic portion 23. Of course, it is understood that the free end portion 211 may 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, so that the detection unit 22 may also collect the pressure information of the elastic portion 23, and the specific arrangement positions of the free end portion 211 and the fixed end portion 212 are subject to the 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 elastic portion 23 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 with the elastic portion 23, 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 moving part 21 made of rubber is not easy to rub the accommodating groove 13, the first sub-display screen 121 and the second sub-display screen 122 in the moving 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. In one example, the elastic portion 23 comprises a spring, and the folding screen 12 is in a fully unfolded state, i.e. an included angle between two sub-display screens is 180 degrees, and the spring can be in a natural relaxation state at this time; the spring may also be under tensile or compressive stress. The folding screen 12 is in a fully folded state, i.e. the angle between the two sub-screens is 0 °, and the spring is now under tensile stress. No matter the elastic part 23 is under tensile stress or compressive stress, the elastic part 23 is elastically deformed in the first sub-display 121, so that the detecting unit 22 can accurately detect the pressure information of the elastic part 23.
The utility model provides a control method of display screen, be applied to the terminal equipment who has two display screens, at least one display screen in two display screens is the folding screen, and the folding screen is under the expanded state, and two display screens set up back to back, and the folding screen includes two sub-display screens, and control method includes: acquiring pressure information of the elastic part acquired by the detection unit, determining the state of the folding screen according to the pressure information, and controlling the display states of the two display screens of the terminal equipment.

The terminal equipment needs to judge the current state of the display screen in the starting or using process so as to determine the display mode of the display screen, avoid the simultaneous lightening of a plurality of display screens and reduce the resource waste. Moreover, since the service life of the display screen is limited, if the time of the display screen in the lighting state is too long, the service life of the display screen is shortened.

For example, when the pressure value is 5N, the folding screen 12 is in the unfolded state, and the folding screen 12 is controlled to be lit. For another example, when the pressure value is 10N, the folding screen 12 is in a folded state, and the folding screen 12 is controlled to be turned off.
In step S220, an included angle between the two sub-display screens may be determined according to the distance information. For example, in step 2201, a mapping relationship between the pressure information and the included angle is set based on the pressure information of the elastic portion 23, and the mapping relationship therebetween is the first arrangement information. When the included angle between the two sub-display screens of the folding screen satisfies a first condition, for example, the included angle is in a range of 100 ° to 180 °, the folding screen is considered to be in the unfolded state, and the pressure value at this time is F1. When the included angle between the two sub-display screens of the folding screen satisfies a second condition, for example, the included angle is in the range of 0 ° to 30 °, the pressure value at this time is F2 when the folding screen is in the folded state. Wherein, the pressure value in the two states satisfies that F2 is greater than F1, that is, the pressure value of the elastic part 23 in the folded state of the folding screen is greater than the pressure value of the elastic part 23 in the unfolded state. According to the rule that the pressure value changes along with the state of the folding screen, a mapping relation can be set between the pressure value corresponding to the state change process of the folding screen and the direct included angle between the two sub display screens of the folding screen, namely first configuration information, the first configuration information can be stored in a memory in advance, and the first configuration information can be modified or supplemented according to actual conditions.
In step S2202, a pressure value of the elastic portion 23 in the current state detected by the sensor may be determined according to the data acquired by the sensor, and an included angle corresponding to the distance value may be determined in the first configuration information in a traversal manner or an index manner according to the first configuration information.
In step S230, in order to conveniently control the display modes of the two display screens, the states of the foldable screen are divided into an unfolded state and a folded state, and when an included angle between the two sub-display screens of the foldable screen meets a first condition, for example, the included angle between the two sub-display screens is in a range of 0 to 30 °, the foldable screen is considered to be in the folded state. When the included angle between the two sub-display screens of the folding screen meets a second condition, for example, the included angle between the two sub-display screens is greater than 30 degrees, the folding screen is considered to be in the unfolded state. Here, the above numerical values are merely used to describe the control method in the present embodiment, and are not used as specific determination numerical values for the folded state.
In step S240, the display states of the two display screens of the terminal device are controlled according to the folding state of the folding screen in step S230. For example, when the folding screen is in the unfolded state, the two sub-display screens of the display screen are controlled to display synchronously or respectively, and the display screen opposite to the display screen is turned off. When the folding screen is in a folding state, the two sub-display screens of the display screen are controlled to be turned off, and the display screen opposite to the display screen displays.

and S340, determining the state of the folding screen according to the included angle.

In step S340, the state of the folding screen can be determined according to the included angle by: and setting a preset angle threshold corresponding to the folding screen state, and comparing the relation between the included angle and the preset angle threshold.
And when the included angle is smaller than or equal to the preset angle threshold value, determining that the folding screen is in a folding state. In one example, the preset angle threshold is set to a fixed value, for example, 30 °, and when the included angle is less than or equal to 30 °, it is determined that the folding screen is in the folded state. When the included angle is larger than a preset angle threshold value, determining that the folding screen is in an unfolded state; for example, when the included angle is larger than 30 degrees, the folding screen is determined to be in the unfolding state.
Or when the included angle is smaller than a preset angle threshold value, determining that the folding screen is in a folding state; for example, when the included angle is less than 30 degrees, the folding screen is determined to be in the folding state. When the included angle is larger than or equal to a preset angle threshold value, determining that the folding screen is in an unfolded state; for example, when the included angle is greater than or equal to 30 degrees, the folding screen is determined to be in the unfolding state.
In another example, the preset angle threshold may also be an angle range interval, for example, when the included angle is smaller than the [30 °, 45 ° ] interval, it is determined that the folding screen is in the folded state, and when the included angle is larger than the (45 °, 60 ° ] interval, it is determined that the folding screen is in the unfolded state.
In another example, the corresponding relationship between the unfolded state and the preset angle threshold may be further refined, for example, when the included angle is located in the interval of [0 °, 30 ° ], it is determined that the folding screen is in the folded state; and when the included angle is positioned in the (30 degrees and 90 degrees), determining that the folding screen is positioned in the first unfolding state, and when the included angle is positioned in the (90 degrees and 180 degrees), determining that the folding screen is positioned in the second unfolding state, and controlling the folding screen and the plane screen to display in different display states according to the folding state, the first unfolding state and the second unfolding state of the folding screen.
In step S350, the display states of the two display screens of the terminal device are controlled according to the state of the folding screen. When the folding screen is in a folding state, controlling the folding screen to display in a first display state, and controlling the other display screen of the two display screens to display in a second display state; the first display state is a turned-off state, and the second display state is a turned-on state. When the folding screen is in the unfolding state, controlling the folding screen to display in a second display state, and controlling the other display screen of the two display screens to display in a first display state; the first display state is a turned-off state, and the second display state is a turned-on state.
In another example, when the folding screen is in the folded state, the folding screen is controlled to be displayed in an off state, and the other of the two display screens is controlled to be displayed in an on state. When the folding screen is in the first unfolding state, the folding screen (the two sub-display screens can synchronously display or respectively display pictures) is controlled to be lightened at a first brightness, and the other display screen in the two display screens is controlled to be displayed in a turned-off state.
