Abstract
A method and apparatus tests a flat display device to inspect for shorts and open circuits in a signal wire by using a magnetic sensor. The inspection method and apparatus scans the magnetic sensor along signal wires in a scan direction crossing multiple signal wires and detects at least one of a short or an open circuit in the signal wires based on current detected by the magnetic sensor.
