Liquid crystal display device with light guide plate convenient for repair

Abstract

The invention discloses a liquid crystal display device with a light guide plate convenient for repair and relates to the technical field of the liquid crystal display, and the problem of tedious andinconvenient repair operations of a liquid crystal display device in the prior art is solved. The technical solution is that the device includes a back plate with a receiving cavity, a fixed ring witha receiving cavity set on the back plate, the light guide plate set in the receiving cavity, a reflective sheet set on a side of the light guide plate facing away from the fixed ring, an optical filmset inside the fixed ring, a liquid crystal panel set on a side of the optical film facing away from the light guide plate, a fixed member set in the fixed ring, and a limit plate which is fixedly connected to the fixed ring and is located on a side of the liquid crystal panel facing away from the optical film. During a repair operation, a fastening bolt is loosened, then a fastening bar slides out of a fastening groove, so the back plate and the fixed ring are separated, therefore, the light guide plate can be directly replaced, the workload of the repair operation is greatly reduced, and the repair operation is more convenient and faster.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, more specifically, it relates to a liquid crystal display device which is convenient for repairing a light guide plate. Background technique [0002] As a display component of electronic equipment, liquid crystal display devices have been widely used in various electronic products. Existing liquid crystal display devices generally include a liquid crystal panel and a backlight module disposed at the bottom of the liquid crystal panel. [0003] The backlight module includes a backplane with an accommodating groove, a reflective sheet, a backlight source, a light guide plate and an optical film located in the accommodating groove in order from bottom to top, and a plastic frame fixedly connected to the backlight board; the plastic frame surrounds the optical The diaphragm is arranged and used for fixing the optical diaphragm. During the manufacturing process of the liquid crystal di...

AI Technical Summary

Problems solved by technology

Due to the defects in the existing technology, when the light guide plate in the liquid crystal display device fails, we can only rework and reorganize the liquid crystal display device. When performing rework and reorganization, we need to remove the liquid crystal panel from the backlight module Disassemble, and then disassemble each component above the light guide plate in turn, and then replace the light guide plate, so that the workload of the repair operation of the liquid crystal display device is large, and the repair operation is cumbersome and inconvenient
