Abstract:
1. A drive circuit for driving a row of pixel in a display or imaging application having a plurality of pixels, the drive circuit comprising: an output terminal connected to a gate line or the row, the gate line connected to the gate terminal of a switching transistor of a pixel in the row; a drive transistor connected to the output terminal, the drive transistor for transferring a gate selecting signal to the gate line of the row; a series of control transistors comprising a plurality of transistors serially connected, the series of control transistors having a first terminal and a second terminal at opposite ends of the series of control transistors, the first terminal of the series of control transistors connected to the gate terminal of the drive transistor, the series of control transistors for transferring an addressing signal from the second terminal of the series of control transistors to the gate terminal of the drive transistor to control the transferring of the gate selecting signal to the gate line of the row; and a plurality of control signals connected to the gate terminals of the plurality of control transistors for controlling the transferring of the addressing signal to the gate of the drive transistor, herein the drive transistor, the plurality of control transistors and the switching transistor of the pixel are each a thin film transistor.
