As shown in fig. 2, the receiving portion 120 includes a drum 121 and a rotating shaft 122 located inside the drum 121. The drum 121 may be a hollow cylinder, and the rotating shaft 122 may be located on a central axis of the cylinder. One end of the bending region 112 of the display screen 110 is connected to the rotation shaft 122. The rotating shaft 122 is connected to a motor, and the rotating shaft 122 is driven by the motor to rotate so as to drive the bending region 112 to wind around the rotating shaft 122. In addition, the display apparatus 10 may be further provided with a rotation adjusting device that adjusts a rotation direction of the rotation shaft 122, and the rotation adjusting device may adjust the rotation shaft 122 to rotate in a clockwise direction or to rotate in a counterclockwise direction. In addition, a key for selecting the rotation direction can be arranged on the display device, so that the operation of a user is facilitated.
Referring also to fig. 1, in some embodiments of the present application, the displacement detecting part 130 may include two displacement detecting devices located at opposite sides of the display screen 110. As shown in fig. 1, two displacement detecting means are respectively located at upper and lower sides of the display screen 110, are parallel to each other, and extend from one end of the planar region 111 to the bent region 112, and are connected to the receiving portion 120.

Wherein one end of the connecting rod 131 is connected to the sliding rail device 132, and the other end is connected to the drum 121 of the accommodating device 120. The length of the connecting rod 131 may be matched to the width of the control unit 113 to avoid the control unit 113 from being damaged during the curling process. During the rolling process of the screen, the connecting rod 131 slides inwards with the rotating drum 121 through the sliding rail device 132, so that the screen is prevented from being damaged due to pulling.

As shown in fig. 2 and 3, the sliding rail device 132 can be extended and contracted according to the curling state so as to facilitate the movement of the connecting rod, and reduce the risk that the screen is pulled due to the curling and is damaged.
The sliding rail device 132 may be a telescopic device, which may be a sliding sheet or a brush sliding on a rail, or a telescopic rod-shaped structure. Fig. 4 and 5 show an example of a slide rail device. Fig. 4 shows a side view of a slide rail apparatus of a display apparatus according to an embodiment of the present application in an unfolded state.

Fig. 4 and 5 show the state of the slide rail device 132 in the unfolded state and the rolled state of the screen, respectively. When the screen curls, thereby the regional winding of buckling is accomodate in the rotary drum in the pivot under the drive of pivot, at the in-process that curls, the expansion region of screen reduces gradually, for preventing that the screen from being dragged and damaging, each loop bar nestification among the slide rail device deepens to the length of slide rail device reduces along with the expansion regional reduction of screen in step, therefore can reduce the risk that the screen damaged.
In some embodiments of the present application, the loop bar may be made of a resistive material. For example, the surface of the sleeve can be uniformly coated with a layer of resistance paste DAP (diallyl phthalate). The loop bar formed by the method has excellent smoothness, wear resistance and chemical corrosion resistance, and has small dynamic noise. When the screen curls, the loop bar can smoothly stretch out and draw back, so that the resistance of the loop bar changes along with the change of the loop bar, and the measurement precision can be improved.
In some exemplary embodiments, the sliding rail device may also include a sliding piece or a brush sliding on the rail, and the effective length or the resistance of the sliding rail device is adjusted through the movement of the sliding piece or the brush, so as to generate a signal of the corresponding screen unfolding or rolling degree.
Correspondingly, the displacement sensor may be a linear displacement sensor that converts the mechanical displacement of a straight line into an electrical signal. For the slide rail device shown in fig. 4 and 5, the displacement sensor detects the amount of the screen curling by detecting the change of current or voltage according to the change of resistance of the slide rail device, and generates a displacement detection signal to be transmitted to the control unit, and the control unit adjusts the display area of the screen in real time according to the curling state of the screen according to the received displacement detection signal.
In the display device of the embodiment of the application, the displacement sensor detects the amount of the screen curling by detecting the change of current or voltage according to the resistance change of the sliding rail device, and generates a displacement detection signal to be transmitted to the control unit, and the control unit adjusts the display area of the screen in real time according to the curling state of the screen according to the received displacement detection signal. Therefore, the display device can improve user experience and reduce the overall power consumption of the display device.
The application also provides a display control method of the display device. The display device of the application comprises a display screen, an accommodating part and a displacement detection part. The display screen comprises a plane area and a bending area which is arranged adjacent to the plane area. The accommodating part is positioned on one side of the display screen close to the bending area and used for accommodating the bending area of the display screen so as to change the display area of the display device. The mobile detection part is positioned on one side of the display screen departing from the light emitting direction and is perpendicular to the accommodating part, and the displacement detection part is displaced along with the curling or the unfolding of the display screen.
In addition, the display screen further comprises a control unit, and the control unit is used for adjusting the display area of the display screen according to the displacement change of the displacement detection part. The display device further includes a displacement sensor, and the displacement sensor detects a displacement change of the displacement detecting part, generates a displacement detection signal, and transmits it to the control unit of the display screen, and the control unit adjusts a display area of the display screen according to the received displacement detection signal.
Each component of the display device may have substantially the same structure as that described with reference to fig. 1 to 5, and will not be described repeatedly herein. The control adjustment method of the display area when the display device is rolled or unrolled is described in detail below with reference to fig. 4 and 5.
As shown in fig. 4 and 5, the displacement detecting part 130 may include two displacement detecting means located at opposite sides of the display screen 110. One end of the slide rail device 132 is fixed at the end of the display screen 110, and the other end is connected to the connecting rod 131. The connecting rod 131 has one end connected to the slide rail device 132 and the other end connected to the drum 121. During the rolling process of the screen, the connecting rod 131 carries the rotating drum 121 to slide inwards through the sliding rail device 132.
When the screen is in the unfolded state as shown in fig. 4, the length of the sleeve is L1, the length of the connecting rod is d, and the length of the screen display area is L1+ d. The effective resistance of the resistance paste in the unfolded state of the loop bar is R1, and the voltage across the loop bar is U1 ═ L1 × (R) 1.
When the screen is in the rolled state as shown in fig. 5, the length of the sleeve rod is L2, the length of the connecting rod is d, and the length of the screen display area is L2+ d. The effective resistance of the resistance paste changed to R2 after the loop bar contracted, at which time the voltage across the loop bar was U2+ L2 × R2.
Therefore, when the loop bar moves telescopically, the effective resistance of the loop bar changes. At this time, if a constant current I is applied to both ends of the loop bar, the corresponding voltage is also changed, so that the relationship between the loop bar length and the voltage can be obtained: l ═ k × U, where k is a constant. Therefore, the degree of the curling of the screen can be judged by detecting the voltage signals at the two ends of the loop bar, and the display area of the screen is adjusted.
In addition, when the screen curls, thereby the regional winding is accomodate in the rotary drum in the pivot under the drive of pivot in the bending, at the in-process that curls, the expansion region of screen reduces gradually, for preventing that the screen from being dragged and damaging, each loop bar nestification among the slide rail device deepens to the length of slide rail device reduces along with the expansion regional reduction of screen in step, therefore can reduce the risk that the screen damaged.
Furthermore, the manner of detecting changes in the slide rail device is not exclusive. The Hall displacement sensor can be used for detecting the change of the magnetic field of the slide rail device to obtain the change value of the slide rail device or the photoelectric displacement sensor is used for measuring the change of the pulse light reflection time interval to obtain the change value of the slide rail device.
Therefore, the display device detects the change of the displacement detection part through the displacement sensor, generates a displacement detection signal and transmits the displacement detection signal to the control unit, and the control unit adjusts the display area of the screen in real time according to the received displacement detection signal and the curling state of the screen, so that the user experience is improved, and the overall power consumption of the display device is reduced. In addition, the displacement detection device of the display device comprises the sliding rail device, and the length of the sliding rail device is synchronously changed along with the curling or the unfolding of the screen, so that the risk that the screen is damaged due to pulling can be reduced, the display stability of the display device is improved, and the service life of the display device is prolonged.
The foregoing is only a preferred embodiment of the present application and it should be noted that, for a person skilled in the art, several modifications and refinements can be made without departing from the principle of the present application, and these modifications and refinements should also be regarded as the protection scope of the present application.
