A Testing Method on a Thin Film Transistor Array for Active Matrix Organic Emitting Diode
-
Abstract
A novel method is used to evaluate the quality of a TFT array for an active matrix OLED,which can measure the characteristics of TFTs in a 2-T pixel circuit and detect the defects.The proposed testing method is carried out simultaneously with the fabrication processes.Without changing the fabrication processes,only one mask is added to judge the working states of the switch transistor and driving transistor in the pixel circuit.It is a current testing method,which has several advantages including fast response time,high precision,and no damage to the display. -
