Problems solved by technology

[0012] In prior art 2, there is also no disclosure of a structure for supporting the bottom surface of the flexible display when the screen of the flexible display wound around the cylindrical rotating member expands. In this state, the flexible display is prone to bending or drooping.
[0013] In addition, in the prior art 2, when the screen of the flexible display wound around the cylindrical rotating member expands and the screen shrinks, it is difficult to apply a constant tension to the flexible display, and excessive load may be applied to the flexible display.
[0014] Moreover, the structure of winding flexible displays is difficult to apply to smaller portable devices, and the radius of curvature of the winding portion will be deformed, so that deformation control for flexible displays as a whole may become difficult

Abstract

The invention provides a flexible display device. A flexible display device according to an embodiment of the present invention includes a main body, a moving plate, a first pulley, a second pulley, a driving track, and a flexible display. The flexible display is combined with the outer sides of the moving plate and the driving track, and the driving track forms continuous tracks by itself or together with the moving plate. Therefore, it is possible to provide a flexible display device, wherein the moving plate and the driving track support the flexible display, and a constant tension can be maintained throughout the driving track section, and the flexible display can be spring back. Minimized and able to prevent damage caused by flexible display bending etc.

Description

technical field [0001] The present invention relates to a bendable flexible display, and more particularly, to a flexible display device in which the area of ​​the flexible display exposed from either side can be changed. Background technique [0002] With the development of a flexible display that can be bent while displaying image information, research and development of a foldable device in which the flexible display is applied in a device having two bodies and a folding structure (eg, a hinge portion) has been carried out. In such a device, since the flexible display can be arranged in the whole of the two main bodies by the folding structure, a large-screen display can be realized in the device. [0003] As yet another device using a flexible display, research and development have been conducted on a roll-type device in which the display can be wound. In such a device, the overall size or area of ​​the display will be reduced as the flexible display is wound, and the o...
