摘要：
A testing method for an optical tough panel includes the steps of: coupling a negative voltage to a common line to turn off an optical sensing element; coupling a positive voltage to a readout line; turning on a switching device to have the positive voltage charge the optical sensing element through the readout line and the switching element; turning off the switching element for a predetermined period of time; coupling the negative voltage to the readout line; turning on the switching element again to read a voltage variation of the optical sensing element through the readout line and the switching element; and analyzing the voltage variation. The present invention further provides an array tester.
