ANALYSIS METHOD AND APPARATUS FOR POOR LCD MODULE BY USE OF CAMERA MULTIPLE FOCUS PROCESS

摘要

The invention disclosed is to be able to take pictures using the camera at each floor of the LCD module, as by using a video signal recording layer by layer on a multi-focus type LCD module failure analysis method for and an apparatus for analyzing a failure state, the camera one operates the focus of a previously set-up procedure for a non-defective LCD module and, based on data generated by generating and storing a plurality of reference data using a recording signal; By operating a focus of a camera in a predetermined sequence taking the LCD module for inspection, and then, by using the recording signal comparison data generating process of generating a plurality of comparison data; And the comparison data and the reference data is characterized by being a defect analysis process to be compared to each floor, and floor outputs each state on the display to an inspector analyze the floor bad.
