Patent ID: 7435302

Claim:
A method of treating a liquid crystal display device, comprising: a measurement process comprising: providing a rotating member having a shaft and a plurality of bristles extending radially from a surface of said shaft, providing a substrate adjustment member having a first conductor pattern and a second conductor pattern arranged within a first plane of said substrate adjustment member, and simultaneously measuring electrical potentials of each of said first and said second conductor patterns by moving said substrate adjustment member in an upward direction towards said rotating member, wherein said first and said second conductor patterns are electrically charged by making contact with the plurality of bristles of said rotating member; a correction process which changes a position of said rotating member with respect to said first plane, when the measured electrical potentials of said first conductor pattern or said second conductor pattern equals or exceeds a reference electrical potential range, while said rotating member is moving; and a substrate surface treatment process which allows, after said correction process is performed, said rotating member and said liquid crystal display device to come into contact with each other, and simultaneously moves said rotating member and said liquid crystal display device, so as to perform a surface treatment on said liquid crystal display device.
