Description

Technical field

[0001] The invention relates to the technical field of liquid crystal display screen detection devices, in particular to a liquid crystal display screen frame flatness detection device. Background technique

[0002] Liquid crystal display is a kind of flat panel display, used for the screen display of TV and computer. The advantages of this display are low power consumption, small size and low radiation. The liquid crystal display uses two pieces of polarized materials. Liquid crystal solution, when the current flows through the liquid, the crystal will be rearranged to achieve the purpose of imaging. Therefore, the detection of the frame balance of the LCD screen is an important part of the quality inspection of the LCD screen, but the existing LCD screen detection device is not only The detection is not accurate and the efficiency is low. Summary of the invention

[0003] The purpose of the present invention is to provide a device for detecting the flatness of t...
