Patent ID: 8237692

Claim:
A flat panel display, comprising: a glass substrate having a plurality of pixels; a source driving unit electrically connected to the pixels; and a gate driving unit having N shift registers, wherein N is a positive integer, n is a positive integer from 1 to N, and the n th shift register comprises: a pull-up unit coupled to an output terminal for outputting at the output terminal, when the pull-up unit is turned on, a first portion of an n th output signal according to one of a first clock signal and a second clock signal; a driving unit comprising a first switch device having a first terminal for receiving a trigger signal and a second terminal for outputting a driving voltage to drive the pull-up unit according to the trigger signal; a pull-down unit coupled to the output terminal for outputting at the output terminal, when the pull-down unit is turned on, a second portion of the n th output signal, the second portion being subsequent to the first portion; and a driving control unit comprising a second switch device having a first terminal for receiving the other of the first clock signal and the second clock signal, and a control terminal controllable by the driving voltage output from the second terminal of the first switch device, for providing a DC level voltage to drive the pull-down unit according to the other of the first clock signal and the second clock signal, wherein the trigger signal is an (n−1) th output signal for n≠1, and a start signal for n=1, and the DC level voltage is between a high level voltage of the first portion and a low level voltage of the second portion of the n th output signal.
