Liquid crystal display device

摘要

A liquid crystal display device which includes a plurality of OCB liquid crystal pixels arrayed substantially in a matrix, and a driver circuit which cyclically writes a non-video signal and a video signal as a pixel voltage in each of the liquid crystal pixels. The liquid crystal display device further includes a control circuit which sets a first period and a second period different in length from the first period such that a total time length of the first period and the second period does not exceed one frame period, and controls the driver circuit to execute write of the non-video signal for the liquid crystal pixels in the first period and to execute write of the video signal for the liquid crystal pixels PX in the second period.

1. A liquid crystal display device, comprising:
a plurality of OCB liquid crystal pixels which are arrayed substantially in a matrix and which include red, green and blue color filters; a driver circuit which cyclically writes a non-video signal and a video signal as a pixel voltage in each of said liquid crystal pixels; and a control circuit which controls an operation timing of said driver circuit, wherein said control circuit is configured to set, in one frame period, a first period shorter than the frame period and a second period shorter than the frame period and partly overlapping the first period, and is configured to control the driver circuit to execute write of a black-level non-video signal for all of said liquid crystal pixels in the first period within a single frame period, to execute write of the video signal for all of said liquid crystal pixels in the second period within the single frame period, and to alternately execute the write of the non-video signal and the write of the video signal in units of one or more horizontal periods in an overlapping part of the first period and the second period, and is configured to reverse a polarity of the pixel voltage to the plurality of liquid crystal pixels in at least any one of column reverse and frame reverse and wherein a period from a start of the write of non-video signal to completion of the write of the video signal is equal to or shorter than the single frame period.
