  • Patent number: 7362124
    Abstract: A method and apparatus are provided for inspecting an electrical defectiveness of a liquid crystal display substrate. The method includes shorting ESD protection devices with a conductive shorting bar to form a current path on each of signal wirings of the substrate, supplying a current to the signal wirings, and determining a defectiveness of the signal wirings depending on the current flowing on the signal wirings.

  • Patent number: 7301360
    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.

  • Patent number: 7046030
    Abstract: A method and apparatus for testing a liquid crystal display device are provided to detect a defect location precisely and rapidly without requiring a jig. The method includes providing a substrate to inspect, wherein the substrate includes signal wirings, drive switches and capacitors formed in an effective display area of the substrate; radiating a light onto an inspection switch device and thereby supplying an inspection voltage from an inspection line to one of the drive switches through the signal wirings, so as to charge one of the capacitors; and determining if there is a defect in the effective display area of the substrate by reading the charged voltage of the capacitor.

  • Patent number: 7009405
    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.
