Abstract :
The performance criteria and corresponding design specifications for channel buffer amplifiers in state-of- the-art column driver ICs of active-matrix LCD (AMLCD) applications are presented. And the relationships between the amplifier characteristics and the display image quality are defined. In addition, several display patterns and their driving waveforms that enable the prediction of the performance of channel buffer amplifiers in real panel applications are presented.
