The present disclosure relates to a field of flexible display screen, and more particularly, to a flexible screen support device and a flexible screen.
With the development of material technology, display screens can be made into a bendable form. Devices adopting flexible display screens enjoy many advantages, such as convenient to carry, bendable, freely deformable, etc. However, for now, the devices adopting flexible display screens also have some disadvantages, such as poor maneuverability due to lack of reliable support.
Traditional solution to the above problem is to attach the flexible display screen to a supporting body with a fixed shape (e.g. a curved surface). However, this solution only utilizes a good attaching property of the flexible display screen, which limits to display on the curved surface, without making full use of the freely deformable characteristic of the flexible display screen.
Based on the above deficiencies, the present disclosure provides a flexible screen support device, which fully utilizes the freely deformable characteristic of the flexible display screen to benefit the diversification of the display of the flexible screen.
A flexible screen support device provided in the disclosure, configuring for supporting a flexible screen, includes a support plate; a first telescopic bracket; and a plurality of second telescopic brackets located on two opposite sides of the first telescopic bracket; wherein the first telescopic bracket and the plurality of second telescopic brackets couple the support plate and the flexible screen; wherein the first telescopic bracket and the plurality of second telescopic brackets drive the flexible screen to form a curved surface.
A flexible screen provided in the disclosure, includes a display surface, a back surface, and the flexible screen support device; wherein the flexible screen support device couples the back surface.
The flexible screen support device described in present disclosure supports the support plate and the flexible screen through the first telescopic bracket and a plurality of second telescopic brackets. The expansion and contraction of the first telescopic bracket and a plurality of second telescopic brackets in different degrees drive the flexible screen to form a curved surface, thus the flexible screen can have diversified display modes.
In order to more clearly explain technical solutions in the embodiments of the present disclosure, drawings that need to be used in the embodiments will be briefly introduced below. Obviously, the drawings in the following description are only some embodiments of the present disclosure. For those ordinarily skilled in the field, other drawings can be obtained without paying creative work.
