Thin film transistor array, display panel, method for inspecting the thin film transistor array, and method for manufacturing active matrix organic light emitting diode panel

摘要

A thin film transistor (TFT) array comprises: a drive TFT for driving an organic light emitting diode (OLED), which is an electroluminescence (EL) device; first common wiring disposed for performing a current source or a current sink for the OLED; second common wiring disposed for performing a current source or a current sink for the OLED, the second common wiring being connected alternately with the first common wiring for each horizontal line and each vertical column of a pixel; and a switching TFT, which is a connection switch for connecting either one of the first common wiring and the second common wiring to a pixel electrode.
