Tcon PCB automatic detection system and method thereof

Abstract

The invention provides a Tcon PCB automatic detection system and a method thereof. According to the Tcon PCB automatic detection system and the method thereof, an automatic detection device has complete Tcon PCB inspection items; a detection process records the data and results of all the PCB inspection items; an analog receiving unit integrates a traditional to-be-tested screen receiving circuit, and can complete automatic detection comparison on images and screen control signals; a control loop can control a Tcon PCB in real time in order to satisfy higher automated detection requirements; an analog receiving module is an IC which is manufactured by the same process with a test screen driving IC in order to achieve the same receiving capacity with the test screen driving IC; and the analog receiving module IC integrates an image capture function and an image data / screen control signal comparison function. Highly-automated Tcon PCB detection technologies are adopted, the to-be-tested screen receiving circuit is integrated into an image capture and signal comparison unit, and therefore, the error rate of manual detection can be effectively reduced, and the detection efficiency of the Tcon PCB can be improved; and the automated detection technologies are adopted, and therefore, the defects of the manual detection can be eliminated, productivity efficiency can be improved, and debugging steps can be simplified.

Description

technical field [0001] The invention relates to the technical field of Tcon PCB inspection, in particular to a Tcon PCB automatic inspection system and a method thereof. Background technique [0002] The traditional T-con PCB needs to be tested and confirmed with a screen, and then manually confirm the effect of the PCB point screen. The screen to be tested includes a test screen and a receiving circuit. The receiving circuit includes two units: a signal receiving circuit and a driver chip. Manual inspection is time-consuming and requires a long staff It is easy to get tired during work, which leads to errors in detection. It takes a long time to train testing personnel, and it is not easy to train; and the detection efficiency cannot be improved, and the detection yield is greatly affected by human factors. The automatic detection technology proposed in this application can effectively reduce the error rate of personnel detection and improve the detection efficiency of Tcon...
