Title:
スタートパルス垂直信号生成器およびTFT液晶表示装置のゲート駆動方法
Document Type and Number:
Japanese Patent JP4040712
Kind Code:
B2
Abstract:
A start pulse vertical signal generator using a data enable signal for precharging is disclosed. A clock pulse vertical (CPV) signal generator generates a CPV signal by counting a main clock signal and a data enable signal. A pulse signal generator generates reset pulse signals and delayed pulse signals by using a data enable signal and the CPV signal. A pre-start pulse vertical (STV) signal generator generates an STV signal by using the CPV signal and reset pulse signals and delayed pulse signals. Accordingly, the present invention generates the pre-STV signal two clock pulses of the CPV signal before the data enable signal DE is generated.
