DEVICE FOR DETECTING PIXEL STATE OF DISPLAY ELEMENT ARRAY SUBSTRATE

摘要

The present invention provides a detecting device detecting pixel state. The detecting device detecting pixel state may include a lower electrode, an optical-conductive layer, an upper electrode deposited in sequential, a charge collecting electrode formed on a surface of the upper electrode corresponding to a position of a object pixel, a capacitor electrically connected to an end portion of the charge collecting electrode, and a transistor electrically connected to the charge collecting electrode. According to the present invention, as well as a pixel defection, a line defection of a flat display device, a fine pixel defect such as a low-brightness point, a low- flickering point and a spot are easily detected, and the defected flat display device is prevented to proceed in a following process such as module assembling. Thus, a cost for assembling inferior goods may be reduced.
