Method and apparatus for testing liquid crystal display device
View Patent ↗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 an inspection apparatus as a removable portion of the liquid crystal display device; inspecting the display part of the liquid crystal display device using the inspection apparatus; removing the inspection apparatus from the liquid crystal display device after the inspection is completed; and attaching driving circuits to the liquid crystal display device having the inspection apparatus removed therefrom.
1. A method of inspecting a display part of a liquid crystal display device, the method comprising:
providing an inspection apparatus as a removable portion of the liquid crystal display device;
inspecting the display part of the liquid crystal display device using the inspection apparatus;
removing the inspection apparatus from the liquid crystal display device after the inspection is completed; and
attaching driving circuits to the liquid crystal display device having the inspection apparatus removed therefrom,
wherein in the attaching step, the driving circuits are attached to areas of the liquid display device where the inspection apparatus was previously located.
2. A display part of a liquid crystal display device, comprising:
a substrate;
a display circuit on the substrate for performing a display function of the liquid crystal display device;
an inspection apparatus formed at an exterior of the display circuit and being a removable portion of the liquid crystal display device; and
driving circuits attached to the exterior of the display circuit once the inspection apparatus Is removed,
wherein after the display circuit is inspected for any defect using the inspection apparatus, the inspection apparatus is removed from the liquid crystal display device.
