In particular, the functional element 1 may be arranged at the edge of the back plate 100 and towards the flexible display 4.
Here, the rear of the flexible display 4 may refer to a non-display side of the flexible display 4, and the one side may refer to another side opposite to a side where the display area of the flexible display 4 is located. The back plate 100 may refer to a main circuit board, or may be a circuit board separately designed for the functional element 1, and the back plate 100 is not limited herein. In addition, the whole or part of the flexible display 4 may be a display region, and the area occupied by the display region is not limited herein.
Specifically, the display device may be a mobile phone, a tablet computer, another mobile terminal with a display function, or the like. When the display device does not need to use the functional element 1, the flexible display 4 may shield the functional element 1, i.e. the functional element 1 may be fixedly hidden behind the flexible display 4. When the functional element 1 needs to be used, the driving device can drive the flexible display screen 4 to move, so that the functional element 1 is exposed, and then the corresponding function of the functional element is completed. The driving action of the driving device may be automatic or manual, and is not limited herein.
It should be understood that the functional elements 1 described above may refer to those elements that need to be aligned with the display side of the flexible display 4 to perform their respective functions. For example, the display side of the flexible display 4 is oriented to the user, and the functional element 1 is oriented to the user when applied. Specifically, the functional element 1 may be at least one of a camera, a distance sensor, an ambient light sensor, an earpiece and a fingerprint sensor, and the like, that is, the number of the functional elements 1 may be one or more, and the number is not limited herein. When the number of the functional elements 1 is plural, each of them may be referred to as a functional element unit. In addition, the flexible display screen 4 may be a full screen or a non-full screen, which is not limited herein.
For example, when the functional element 1 disposed behind the flexible display 4 includes a fingerprint sensor, the outer surface of the display device does not need to be provided with a fingerprint identification area, so that the display device is more convenient and beautiful.
In addition, the flexible display 4 may be a single screen body, or may be formed by combining a plurality of sub-screen bodies, which is not limited herein. Specifically, when the flexible display 4 is formed by combining a plurality of sub-screen bodies, the sub-screen bodies may or may not be in contact with each other, which is not limited herein. Correspondingly, the driving device may include different driving units for respectively driving the sub-screen bodies of each flexible display 4 to move, so as to expose the corresponding functional elements 1 of the sub-screen bodies of each flexible display 4.
For the moving process of the flexible display 4, for convenience of description, the identification position can be selected to assist description. Specifically, as shown in fig. 1, the functional element 1 may be located at the upper edge of the display device, and the first position 2 of the flexible display 4 is selected as the mark position, where the flexible display 4 is in the first state of shielding the functional element 1. After the driving device drives the flexible display screen 4 to move, the identification position can be moved to the second position 3, and at the moment, the flexible display screen 4 is in the second state of exposing the functional element 1, so that the corresponding function can be realized. It will be appreciated that in the second state a portion of the flexible display 4 is rolled into the interior of the display device.
According to the embodiment of the invention, the flexible display screen 4 can be driven to move by the driving device, so that the functional element 1 positioned behind the flexible display screen 4 is exposed when in use and is shielded by the flexible display screen 4 when in no use, and thus, the limitation of the screen occupation ratio maximization caused by the display area occupied by the functional element 1 is effectively avoided.
In another embodiment of the invention the total display area of the flexible display 4 is the movable display area 13.
In particular, the functional element 1 is located at one end of the display device, and the flexible display 4 may be distanced from the one end to expose the functional element 1 so that the functional element 1 performs its function. After the functional element 1 has completed the function, the flexible display 4 can be close to the end to shield the functional element 1 again, so that the moving direction of the flexible display 4 can be single. When the functional element 1 includes a plurality of functional element units and is dispersed at multiple ends of the display device, the flexible display screen 4 may be far away from any one end of the multiple ends to expose the functional element unit corresponding to the one end, and after one functional element unit completes the function, the flexible display screen 4 may be close to the one end to shield the functional element unit again, and then move again to enable another functional element 1 to function, which may be controlled by a program, and will not be described herein again.
Since the flexible display 4 is the entire display area, the driving device can drive the flexible display 4 to move so as to expose the functional element 1 located at any position.
It should be understood that the end of the display device referred to herein may be any one of a top end, a bottom end, a left end and a right end, and is not limited thereto.
