Abstract
A thin film transistor circuit has a main thin film transistor (), a control input () for controlling the operation of the main thin film transistor and a threshold adjustment capacitor () connected between the control input and the gate of the main thin film transistor. A charging circuit () is used for charging the threshold adjustment capacitor to a desired threshold adjustment voltage. The circuit is used to affect a voltage shift to the voltage applied to the control input. This effectively implements a threshold voltage change by altering the relative voltages on the main transistor gate and the control input.
