Abstract

The invention discloses a bottom case of a display device, which comprises an outer edge and a plurality of first rigid structures, a second rigid structure, a first elastic structure and a second elastic structure arranged in the outer edge; the first rigid structures are arranged in rows at intervals; the second rigid structures are arranged in rows and staggered with the first rigid structure;a first elastic structure ring is arranged at the periphery of the first rigid structure and is used for absorbing the deformation amount generated by the expansion and contraction of the first rigidstructure; a second elastic structure ring is arranged at the periphery of the second rigid structure and is used for absorbing the deformation amount generated by the expansion and contraction of thesecond rigid structure. In the technical scheme of the invention, the expansion and contraction amount of the first rigid structure is absorbed by the first elastic structure; the expansion and contraction amount of the second rigid structure is absorbed through the second elastic structure, so that the external dimension of the case is effectively ensured, and the assembly effect of the bottom case and the display module is ensured.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a bottom case of a display device. Background technique [0002] When the external temperature changes, especially in the process of turning on and off the display module, the display module with a small thermal expansion coefficient and the bottom case with a large thermal expansion coefficient will have a certain dimensional difference in the process of thermal expansion and contraction. value, that is, deformation incongruity. When the size of the display module is small, the difference has little effect on the flatness and structural stability of the display, but when its size exceeds a certain value (400mm), the difference can cause the module to bend, and the combination of the two The structure of the part is deformed and loosened, or even fails and falls off. [0003] In order to deal with the problems of display module bending and structural failure (such as lo...
