MATRIX TYPE DISPLAY APPARATUS AND METHOD FOR DRIVING THE SAME

摘要

A pair of .gamma.1A and .gamma.2A converter circuits (1a,2a) to a pair of .gamma.1C and .gamma.2C converter circuits (1c,2c) use first to third types of first and second .gamma. characteristics to .gamma. convert an input video signal (IS). Selectors (3 to 5) select one pair among three pairs of .gamma. characteristics in accordance with a transmittance to be used for display, a nd select one of the six .gamma. corrected outputs such that both a distributio n area ratio of pixels driven by the video signal as .gamma. corrected by use of the first .gamma. characteristic of the selected pair of .gamma. characteristics and a distribution area ratio of pixels driven by the video signal as .gamma. corrected by use of the second .gamma. characteristic of t he selected pair of .gamma. characteristics are equal to a distribution area ratio specified in advance for the selected pair of .gamma. characteristics.
