Abstract

The embodiment of the invention provides a display device. The display device comprises a reel part and a flexible screen, wherein the reel part comprises an inner shaft, and a step part is formed onthe inner shaft; the flexible screen is wound around the inner shaft from the low side of the step part in a drawing mode, through the step part on the inner shaft, the flexible screen can be smoothlywound around the inner shaft, and the flexible-screen local stress concentration problem caused by a flexible-screen local protrusion, dent or the like is effectively solved; when the flexible screenis unfolded or folded, the end stress concentration problem of the flexible screen is solved, the structural strength of the product is improved, and the service life of the product is also prolonged.

Description

technical field [0001] The present disclosure relates to the field of flexible screen display devices, in particular to a display device. Background technique [0002] The flexible screen can be rolled and spread around the axis to form a new product form that can be stretched and rolled. However, the above-mentioned products have the following technical problems: when the curled screen is curled in multiple layers on the axis, due to the thickness of the screen, steps will be formed at the end, and the steps will squeeze the structure in the screen, causing damage or extrusion deformation of the film material, resulting in display defect, such as figure 1 As shown, one end of the flexible screen is attached to the inner shaft of the reel and wound around the inner shaft. Since the flexible screen has a certain thickness, the end of the flexible screen attached to the inner shaft gradually lifts up the flexible screens that are wound sequentially. , so that the local stres...
