Abstract

The embodiment of the invention discloses a display device. Specifically, the display device comprises a sliding roll rotating shaft and a flexible display panel; a plurality of supporting pieces arearranged on the backlight face of the flexible display panel at intervals; gaps between at least part of the adjacent supporting pieces are filled with a shape memory material; the flexible display panel is at least partially wound on the sliding roll rotating shaft; the backlight face is close to the sliding roll rotating shaft, and the supporting pieces are arranged in the direction perpendicular to the axial direction of the sliding roll rotating shaft; and the shape memory material is used for deforming when the flexible display panel is extruded by the supporting pieces due to winding ofthe flexible display panel or restoring and limiting the positions of the supporting pieces when the supporting pieces are released due to unfolding of the flexible display panel. By means of the structure, warping can be reduced by overcoming creep deformation of the flexible display panel, the flatness of the flexible display panel is kept, the display effect is guaranteed, and the use experience of a user is improved.

Description

technical field [0001] The embodiments of this specification relate to the field of display technologies, and in particular, to a display device. Background technique [0002] With the continuous advancement of science and technology, flexible display panels have become a new trend in the development of electronic equipment. As an important direction in the development of flexible display panels at present, the slide-and-roll technology can flexibly switch the display area of ​​the flexible display panel according to the user's own needs, which greatly improves the user experience. However, in the current sliding technology, the flatness of the flexible display panel is poor after unfolding, and the problem of warping is prominent, which may easily cause poor display and reduce user experience. Contents of the invention [0003] In view of this, the purpose of one or more embodiments of this specification is to provide a display device to solve the technical problems of p...
