Abstract
A novel method and apparatus inspects liquid crystal display. The method and apparatus for inspecting the flat display device scans at least one signal wire by using a magnetic sensor and detects a resistance change of the magnetic sensor to perceive a short in the signal wire. Pixels can be tested using an array of magnetic sensors configured such that each sensor in the array is smaller than the pixel.
