Abstract:
1. A sequential driving method for time-divisionally displaying a plurality of color signals in respective ones of sub-frames forming one frame in a liquid crystal display apparatus including a plurality of data lines, a plurality of gate lines, and a plurality of liquid crystal pixels, each including a liquid crystal cell and a switching element connected between said liquid crystal cell and one of said data lines and having a gate connected to one of said gate lines, comprising the steps of: writing black signals into all of said liquid crystal pixels at a beginning period of each of said sub-frame; sequentially writing one of said color signals into rows of said liquid crystal pixels each row connected to one of said gate lines while said gate lines are sequentially selected after said black signals are written into all of said liquid crystal pixels; and turning ON a respective one of a plurality of backlights each corresponding to one of said color signals at an end period of each of said sub-frames after the one of said color signals is written into all of the rows of said liquid crystal pixels, a level of pixel components of the one of said color signals to be written into one of the rows of said liquid crystal pixels being compensated for, so that a change of an average transmittivity of each of the rows of said liquid crystal pixels is sufficiently small before said end period.
