Abstract

The invention provides a detection device for liquid crystal display panels. The detection device comprises at least one detection circuit board and a movable lighting module; the movable lighting module comprises a plurality of metal ejector pins, a plurality of movable fixing blocks, a plurality of threaded rods and a plurality of servo motors. The detection device for the liquid crystal display panels is provided with the movable lighting module, so that detection operation of the liquid crystal display panels of different sizes is achieved, and the detection cost of the liquid crystal display panels is reduced.

Description

technical field [0001] The invention relates to the detection field, in particular to a detection device for a liquid crystal display panel. Background technique [0002] With the development of technology, more and more users use liquid crystal display devices, so the detection of liquid crystal display panels is becoming more and more important. [0003] Before leaving the factory, the liquid crystal display panel will be tested for lighting. Lighting detection is generally connected to the pad corresponding to the data line of the liquid crystal display panel through the detection device, so as to send R, G, and B drive signals to the pixel units of the liquid crystal display panel, thereby displaying and testing Screen, if the detection screen is abnormal, you can find out the defects of the liquid crystal display panel in advance. [0004] However, existing manufacturers of liquid crystal display panels produce liquid crystal display panels of various sizes to meet the...
