GATE DRIVER INTEGRATED CIRCUIT, AND IMAGE DISPLAY APPARATUS INCLUDING THE SAME

摘要

An image display apparatus includes a display screen on which pixel circuits are disposed in a matrix, each of which includes an EL element, a transistor connected to a first gate signal line, a transistor connected to a second gate signal line, and a driving transistor. A second gate signal line driving unit and a first gate signal line driving unit of a first gate driving circuit apply a control voltage to the first gate signal line and the second gate signal line, respectively. The second gate signal line driving unit of a second gate driving circuit applies a control voltage to the first gate signal line. An ON voltage, a first OFF voltage, and a second OFF voltage are sequentially applied to the first gate signal line. The ON voltage and the first OFF voltage are sequentially applied to the second gate signal line.
