TESTING DEVICES AND METHOD OF LCD ELECTRODE

摘要

The apparatus checks short or disconnection of a transparent electrode of indium tin oxide (ITO) formed on a trasparent glass board in manufacturing LCD panels. The method comprises supplying constant voltage to ITO transparent electrode (B) patterned on glass board (A) via flat conductor (9), arranging a plurality of coupled exclusive logic measuring bodies (3) with two probes at respective electrodes (B), scanning the bodies (3) sequentially and deciding short or disconnection by measuring voltage difference between first and second probes (1)(2) of the bodies (3).
