Problems solved by technology

[0003] At this stage, regardless of the curled shape or the bent shape, there are relatively high requirements for the reliability of the screen body and the material. Because of the contact between the back and the front of the screen body in the curled shape, it is easy to cause friction damage between the screens or generate particles (particles). ) and the risk of stabbing the screen

Abstract

A flexible display device comprises a storage box body, a curling mechanism and a power driving mechanism. The storage box body comprises a containing space and a side opening communicated with the containing space, the curling mechanism is contained in the containing space, and the curling mechanism comprises a supporting structure for supporting the display screen and a transmission structure for driving the display screen to move. The power driving mechanism is contained in the containing space, and the power driving mechanism synchronously drives the supporting structure and the transmission structure so that the display screen can be unfolded or rolled from the side opening. The power driving mechanism comprises a hinge motor for driving the supporting structure and a driving motor for driving the transmission structure, in the whole dynamic folding and unfolding process, the display screen cannot make contact with any mechanism, and the risk that the display screen is damaged is effectively reduced.

Description

technical field [0001] The invention relates to a rollable flexible display, in particular to a flexible display device with a flexible display that can be expanded or contracted from one side of a storage box. Background technique [0002] With the development and popularization of Organic Light-Emitting Diode (OLED) display technology, the application forms of display products are becoming more and more abundant, breaking through the traditional flat static display. The demand is getting stronger and stronger, and the application of the display screen is gradually developing in two directions: the display area can be adjusted (large or small), and the space occupied by the space can be maximized (shrink). They are all produced in response to the demand for large-size display and small volume. With the continuous advancement of flexible technology, the application of flexible OLEDs will become more and more abundant in the future. [0003] At this stage, regardless of the...
