Abstract

An apparatus is provided for recovery of a threshold voltage, Vth, of thin-film amorphous silicon transistors deposited on a substrate and a gate voltage is applied to each of the transistors during use, causing Vth to shift with time. The apparatus detect when the LCD display is not being used, generates a voltage Vg', of opposite polarity with respect to Vg when the LCD display is not being used, and applies Vg' to the gates of the transistors of the LCD display for causing Vth to shift in a direction opposite to that caused by Vg, thereby maintaining an effective driving voltage for the transistor of the LCD display.
