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 an integral part of the liquid crystal display device;
inspecting the display part of the liquid crystal display device using the inspection apparatus;
covering the inspection apparatus with a light cut-off layer after the inspection is completed; and
attaching driving circuits to the liquid crystal display device after the inspection is completed.
2. The method according to claim 1 , wherein in the attaching step, the driving circuits are attached to certain sides of the liquid crystal display device other than those sides of the liquid crystal display device where the covered inspection apparatus is located.
3. 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 as an integral part of the liquid crystal display device at an exterior of the display circuit; and
a light cut-off layer covering the inspection apparatus after the display circuit is inspected using the inspection apparatus; and
driving circuits attached to the liquid crystal display device after the display circuit is inspected using the inspection apparatus.
4. The display part according to claim 3 , wherein the driving circuits are attached to certain sides of the liquid crystal display device other than those sides of the liquid crystal display device where the covered inspection apparatus is located.
