ABSTRACT:
A three-phase clock signal generation circuit for a source driver of TFT-LCDs. A clock signal generation circuit for LCD driver includes: a divider dividing an external main clock signal by two and generating a division clock signal; a three-phase clock signal generator receiving the division clock signal from the divider and sequentially generating first to third-phase clock signals; and a sampling mode selector receiving the first to third-phase clock signals and in response to an external mode selection signal, sequentially outputting the first to third-phase clock signals as three-phase clock signals or simultaneously outputting one of the first to third-phase clock signals as the three-phase clock signals. The three phase clock signal generator comprises first, second and third phase clock signal generators sequentially generating first, second and third clock signals with the division clock signal, respectively.
