Abstract:
1. Apparatus for inspecting an active plate for a liquid crystal display, the active plate having a matrix of active elements coupled to row and column lines on a first of first and second sides of the active plate, comprising: within a single station having an inspection function and a test function, a holder adapted to hold an active plate and to make electrical contact to the row and column lines on the first side of the active plate, a visual image camera positioned to provide visual image data for an active plate in the holder, and an electronic sensor disposed adjacent the first side of the active plate adapted to sense operation of the active plate; a processor electrically coupled to the holder to electrically couple to an active plate in the holder and electrically exercise an active plate in the holder; a visual image processor coupled to the visual image camera receiving the visual image data for an active plate in the holder and processing the visual image data for the detection of faults on the active plate; and, an electronic sensor output processor electrically coupled to the electronic sensor to process the output of the electronic sensor to detect faults during the electrical operation of the active plate.
