A detection device for liquid crystal display module

Abstract

The invention relates to the technical field of liquid crystal display detecting devices, and discloses a liquid crystal display module detecting device. The device comprises a detecting table, the bottom of the detecting table is fixedly provided with a base, a sleeve groove is formed in the middle of the top end of the detecting table, the bottom surface of the sleeve groove is fixedly providedwith a lighting fixture, and sleeves located above the lighting fixture are fixedly mounted on the inner walls of both sides of the sleeve groove. A motor drives a screw to rotate, so that a movable block slides horizontally along a stable groove, the transverse movement of a detecting objective lens is achieved, convenience is provided for the detecting objective lens to detect a liquid crystal display screen transversely, a cover plate is pushed through an electro-hydraulic rod, a support rod drives a slide plate to slide along a fixed rod, the longitudinal movement of the detecting objective lens is achieved, convenience is provided for the longitudinal detection of the liquid crystal display screen by the detecting objective lens, a combination mechanism is used for achieving the lighting detection of the liquid crystal display screen quickly and effectively, convenience is provided for improving the detection efficiency, and detection errors are reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display detection equipment, in particular to a detection device for a liquid crystal display module. Background technique [0002] The liquid crystal display is a flat and ultra-thin display device. It consists of a certain number of color or black and white pixels and is placed in front of the light source or the reflective surface. The power consumption of the liquid crystal display is very low, so it is favored by engineers. Its main principle is to The current stimulates the liquid crystal molecules to generate dots, lines and surfaces with the back light tube to form a picture. The structure of the liquid crystal display is to place a liquid crystal cell in two parallel glass substrates, with a thin film transistor on the lower substrate glass, and a color filter on the upper substrate glass. The rotation direction of the liquid crystal molecules is controlled by the signal and voltag...
