Matrix type display apparatus and method for driving the same

摘要

A gamma 1 A converter circuit 1 a and a gamma 2 A converter circuit 2 a to a lambda 1 C converter circuit 1 c and a gamma 2 C converter circuit 2 c 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, and selects one of the six gamma-corrected outputs such that both a distribution 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 the selected pair of gamma-characteristics are equal to a distribution area ratio specified in advance for the selected pair of gamma-characteristics.
