Gate driving waveform control

摘要

A gate driver and associated method for a double gate liquid crystal display (LCD) is disclosed. A gate driving signal generating circuit, such as coupled shift registers, generates the gate driving signals in response to horizontal synchronization signal. In one embodiment, a phase control circuit, such as logic AND gates, is coupled to receive the outputs of the shift registers for determining phase relationship between the outputs of the shift registers and the horizontal synchronization signal.

1. A double gate liquid crystal display (LCD), comprising:
a plurality of pixel electrodes arranged in a matrix form comprising rows and columns; a plurality of thin film transistors (TFTs) corresponding to the plurality of pixel electrodes, respectively; a gate driver comprising a gate driving signal generating circuit that generates a plurality of gate driving signals in response to horizontal synchronization signal; wherein, with respect to a pair of neighboring columns, sources of the TFTs are connected together through a shared source line; and wherein, with respect to a row of said plurality of TFTs, odd-number TFTs are connected together through a gate line and even-number TFTs are connected together through another gate line; and wherein said gate driver comprises an odd gate driver for generating odd-number gate driving signals that drive the odd-number TFTs of the gate lines, and an even gate driver for generating even-number gate driving signals that drive the even-number TFTs of the gate lines, such that only a portion of each said gate line is driven at a time.
