Abstract

The present invention provides a winding device and a flexible display device. The winding device is used for accommodating a flexible screen and comprises a reel and a supporting piece, and the supporting piece is wound on the reel, wherein the flexible screen comprises a first end and a second end, the first end is connected with a flexible printed circuit board, the flexible printed circuit board is accommodated in a gap formed by the supporting piece, the flexible screen is at least partially wound on the supporting piece, when the second end of the flexible screen is pulled by external force, the flexible screen extrudes the supporting piece so as to shrink the supporting piece, and when the external force is removed, the supporting piece is used for enabling the flexible screen to rebound. According to the technical scheme, the flexible printed circuit board can be prevented from being damaged due to excessive pulling, completeness of components in the area of the flexible printed circuit board is guaranteed, and normal display of the flexible screen is guaranteed.

Description

technical field [0001] The invention relates to the display field, in particular to a winding device and a flexible display device. Background technique [0002] With the development of technology, flexible screens have attracted much attention due to their bendability and flexibility. At present, terminal products can no longer meet the needs of users to pursue large screen and large field of view while being portable, such as mobile phones, tablets, etc., so terminal curling devices have become one of the development trends of display technology in the future. [0003] However, the repeated curling or flattening of the flexible screen in the terminal curling device will cause delamination and pulling damage of the flexible screen, and even the flexible printed circuit (FPC) area is easily damaged due to excessive pulling force. Contents of the invention [0004] In view of this, embodiments of the present invention provide a winding device and a flexible display device....
