Problems solved by technology

Flexible displays usually use the display panel to be folded outwards or inwards, or the rolls are curled to convert the size of the screen. However, when folded in half, the stress in the bending area will be relatively large. When the rolls are curled, with The increase in the number of layers of the display panel wound outside the roller makes the stress of the display panel close to the center of the rotating shaft and away from the center of the reel uneven, and it is easy to cause the display panel to fail due to excessive local stress and cracks. Affect the display effect

Abstract

The invention relates to the technical field of display, and in particular, relates to a curling device which is used for curling a flexible screen body and comprises a plurality of first reels and asupporting frame, and the shaft radiuses of the first reels are the same. The supporting frame supports the multiple first reels, so that the multiple first reels are arranged in parallel, and for atleast two adjacent first reels continuously wound on the flexible screen body, the connecting line of the centers of every two adjacent first reels located at the interval of every two adjacent firstreels is completely located in the flexible screen body. According to the embodiment of the invention, the curling stress borne by the flexible screen body during curling is relatively uniform, and the uniformity of the flexible screen body at different positions is high, so that the display effect of the flexible screen body is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a curling device. Background technique [0002] Flexible display panels, especially flexible OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) have broad application prospects in mobile smart devices, wearable, automotive and other fields. Flexible display panels also have foldable, rollable, stretchable characteristics. In particular, the display panel that can be rolled up can effectively store large-sized displays, effectively save space, and can also determine the display area according to requirements. Flexible displays usually use the display panel to be folded outwards or inwards, or the rolls are curled to convert the size of the screen. However, when folded in half, the stress in the bending area will be relatively large. When the rolls are curled, with The increase in the number of layers of the display panel wound outside the roller makes t...
