Abstract
Despite rapid advances in science and technology of liquid crystal display
(LCD); elimination of motion-related artifacts and preservation of color purity in
moving images have remained elusive because gray-scale to gray-scale response time,
i.e., time taken to switch pixels from one gray-scale to another depends on the
initial and final gray shades. A technique wherein gray scale to gray scale response
times are less dependent on the initial and final gray shades as compared to other
addressing techniques for driving matrix LCD is reported. We also found that the
response times are about the same as that of a pixel driven with simple square
waveforms and, therefore, the effect of duty cycle due to matrix addressing is
minimal with distributed waveforms of this technique.
