Title: INSPECTION DEVICE AND INSPECTION METHOD FOR LIQUID CRYSTAL PANELS
Abstract:
An inspection device, which is capable of detecting failure modes for display unevenness in an inspection phase before a drive circuit is installed, is provided. The inspection device (100), which checks for display unevenness in a liquid crystal panel (50), is provided with a camera (20) for capturing an image of the liquid crystal panel (50), a control device (32) for controlling the camera (20), a luminance distribution measuring device (36) for measuring luminance distribution on the basis of image data captured by the camera (20), and a storage device (34) that is connected to the control device (32). The storage device (34) contains luminance distribution data and a determination program (35) that determines display unevenness by comparing the luminance distribution data with accumulated luminance distribution data. An accumulated data storage device (38), in which the accumulated luminance distribution data is stored, is connected to the control device (32), and the accumulated luminance distribution data includes data for determination results for display unevenness after a mounting step.
