Description

technical field

[0001] The patent of the present invention relates to the technical field of liquid crystal screens, in particular to a liquid crystal screen detection system. Background technique

[0002] TFT LCD automatic optical inspection AOI (Automated Optical inspection) system is an indispensable and important link in the production of modern TFT LCD screen industry. A liquid crystal screen detection system in the prior art includes: a lighting fixture console, an image acquisition device, an image processing device and a management server. The detection process includes the following steps: the lighting fixture console lights up the liquid crystal screen to be tested, and the image acquisition device (such as an area array CCD camera) collects the image information of the liquid crystal screen and converts it into an electrical signal and sends it to the image processing device. Process the received electrical signal, and judge whether there is a defect in the LCD s...
