Abstract
A shift register unit provides a gate voltage to a nth pixel of a liquid crystal display and includes first to third N-type transistors. Gates of the first and second N-type transistors respectively receive gate voltages of n-2th and n-2th pixels. First ends of the first and second N-type transistors respectively receive first and second input signals. Second ends of the first and second N-type transistors are coupled to a gate of the third N-type transistor The gate voltages of the n-2th and n-2th pixels respectively control conduction of the first and second N-type transistors so as to allow the first and second input signals to selectively conduct on the third N-type transistor. A first end of the third N-type transistor is coupled to a first or second clock signal, and a second end is a voltage output end coupled to the nth pixel.
