THRESHOLD VOLTAGE ADJUSTMENT IN THIN FILM TRANSISTORS |
摘要 |
A thin film transistor circuit has a main thin film transistor ( 10 ), a control input ( 12 ) for controlling the operation of the main thin film transistor and a threshold adjustment capacitor ( 14 ) connected between the control input and the gate of the main thin film transistor. A charging circuit ( 16,18 ) is used for charging the threshold adjustment capacitor to a desired threshold adjustment voltage. The circuit is used to effect 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.
