Title:
LIQUID CRYSTAL DISPLAY DEVICE AND METHOD OF DRIVING SAME
Document Type and Number:
WIPO Patent Application WO/2016/042885
Kind Code:
A1
Abstract:
The purpose of the present invention is to realize a liquid crystal display device of a field sequential scheme capable of suppressing the occurrence of color shift and flicker. One frame period is divided into a plurality of fields, the number of which is greater than the number of lighting patterns. Provided are: a liquid crystal state value obtaining unit(131) for obtaining a liquid crystal state value at the end time of a display field on the basis of an input gray-scale value of the display field and a liquid crystal state value (a gray-scale value corresponding to an alignment state of liquid crystal molecules) at the end time of a previous field (a field right before the display field); and an application gray-scale value obtaining unit(133) for obtaining an application gray-scale value of the display field by correcting the input gray-scale value of the display field on the basis of the liquid crystal state value at the end time of the previous field. The application gray-scale value obtaining unit (133) obtains the application gray-scale value such that a display luminance at each field becomes a display luminance corresponding to the input gray-scale value.
