Liquid crystal display device and backlight module

Abstract

The invention belongs to the field of liquid crystal display and in particular relates to a liquid crystal display device and a backlight module. The liquid crystal display device comprises a middle frame, a backplate and a liquid crystal display panel, wherein the liquid crystal display panel is arranged on a supporting surface of the middle frame; the middle frame comprises multiple member units; a distance is arranged between the adjacent member units; the liquid crystal display device further comprises a supporting piece used for providing assistance in supporting the liquid crystal display panel; the supporting piece is fixedly arranged on the backplate and positioned between the two adjacent member units; and the supporting surface of the supporting piece is aligned with the supporting surface of the middle frame. According to the invention, because the supporting piece of the liquid crystal display panel is additionally arranged on the liquid crystal display device, the supporting piece can be placed between the two member units to provide middle supporting force when the distance between the two adjacent member units is larger so that the supporting force obtained by the liquid crystal display panel is more uniform and the local stress is prevented from being overlarge.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and more specifically relates to a liquid crystal display device and a back module. Background technique [0002] Existing liquid crystal display devices generally include components such as a front frame, a liquid crystal display panel, a middle frame, a backlight module, and a back cover. The backlight module includes components such as an optical film, a light guide plate, and a light bar. The back covers have different functions. The front frame is mainly used to fix the LCD panel and prevent it from jumping out. It is used to carry optical film, light guide plate, light bar and other components, and to ensure the flatness of the backlight module. [0003] In order to save costs, some liquid crystal display devices adopt a segmented middle frame, the middle frame includes a plurality of component units, the component units are respectively fixed on the back plate or the front frame, and...
