AI Technical Summary

Technical Problem

Conventional LCOS display panels face challenges in suppressing color breakup during rapid eye movements due to insufficient time for data transfer and liquid crystal response in high-speed field sequential driving, particularly in applications like virtual and augmented reality where frequent viewpoint changes occur.

Method used

The liquid crystal display device employs a field sequential driving method that divides the scanning process into multiple periods for each color, allowing for incomplete images to be displayed and overlapped within a frame period, effectively doubling or tripling the switching frequency without increasing data write time or transfer rate.

Benefits of technology

This approach enhances color breakup suppression, achieving the same effect as quadruple or sextuple-speed drive while reducing power consumption and ensuring sufficient time for liquid crystal response.

Abstract

To provide a liquid crystal display device with which it is possible to enhance a color breakup suppression effect.SOLUTION: Provided is a liquid crystal display device for displaying a color image in units of one frame period by field sequential drive and comprising a liquid crystal display panel having a plurality of pixels and a liquid source for supplying light in each RGB color to the liquid crystal display panel. The one frame period includes a R image display period for displaying an image in R color, a G image display period for displaying an image in G color, and a B image display period for displaying an image in B color, and at least one of the R image display period, the G image display period, and the B image display period includes a plurality of incomplete image display periods for displaying a single-color incomplete image that appears incomplete to the eyes, with a plurality of incomplete images overlapping each other presenting display of a single-color complete image that appears complete to the eyes.SELECTED DRAWING: Figure 1
