Abstract:
1. A liquid crystal display apparatus for displaying video by driving a liquid crystal panel based on an input video signal, the liquid crystal display apparatus comprising: a liquid crystal panel having a plurality of source lines and a plurality of gate lines; a frequency converting section for generating an output video signal by inserting one non-image signal, which is to be concurrently written into pixels on L (L is an integer equal to or greater than two) gate lines of the liquid crystal panel, for one line, between image signals composing the input video signal, for corresponding L lines, and adjusting a number of horizontal scanning periods of the output video signal so that a number of horizontal scanning periods composing one frame period is (L+1)×(2N+1) (N is an integer); and a driver for driving the liquid crystal panel based on the output video signal generated by the frequency converting section, wherein the frequency converting section increases/decreases a number of horizontal scanning periods included in a vertical blanking period, thereby adjusting the number of horizontal scanning periods composing one frame period.
