Problems solved by technology

[0003] At present, almost 100% of LCD module screen manufacturers use manual inspection methods. The main bottleneck is that the process of LCD module screens is relatively complicated.
However, with the development of liquid crystal display technology, the resolution and quality requirements of LCD module screens are getting higher and higher, and the disadvantages of traditional manual inspection are becoming more and more obvious.

Abstract

The invention provides a liquid crystal module screen detection device. The liquid crystal module screen detection device comprises a rotary disk, a signal instrument, a color analysis meter, an industrial area array camera, and an industrial control unit. The rotary disk is provided with a bearing plate. The signal instrument is connected with the industrial control unit. The industrial control unit is used to control the rotary disk, and rotates a detected liquid crystal module screen to a liquid crystal display flicker degree detection station or a liquid crystal display lightening frame detection station. When the detected liquid crystal module screen is on the liquid crystal display flicker degree detection station, the industrial control unit controls the color analysis meter to detect liquid crystal display flicker degree on the detected liquid crystal module screen. When the detected liquid crystal module screen is on the liquid crystal display lightening frame detection station, the industrial control unit controls the industrial area array camera to acquire images of lightening frames of the detected liquid crystal module screen, and transmits the acquired images to the industrial control unit to detect image quality. The device greatly improves detection efficiency of the liquid crystal module screen.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to a liquid crystal module screen detection device. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is widely used in TVs, mobile phones, monitors and other electronic products due to its advantages of stable picture, vivid image, radiation elimination, space saving and energy saving. Dominance in the field of flat panel displays. [0003] At present, almost 100% of LCD module screen manufacturers use manual inspection methods. The main bottleneck is that the process of LCD module screens is relatively complicated. However, with the development of liquid crystal display technology, the resolution and quality requirements of LCD module screens are getting higher and higher, and the disadvantages of traditional manual inspection are becoming more and more obvious. Contents of the invention [0004] (1) Technical problems to be solved [000...
