LIQUID CRYSTAL ALIGNMENT TEST APPARATUS AND METHOD

摘要

A liquid crystal alignment test method includes: connecting a liquid crystal array substrate to be tested with a liquid crystal alignment test apparatus; applying corresponding voltages to signal input ports of the liquid crystal array substrate via a voltage providing device and then to execute an image check for the liquid crystal array substrate; and detecting resistance values of each two signal input ports of the liquid crystal array substrate via s resistance detection device to judge whether each two of the signal input ports are short-circuited.
