Liquid crystal display apparatus
First Claim
1. :
- A liquid crystal display apparatus comprising;
a pair of substrates, at least one of which is transparent;
a liquid crystal layer disposed between the pair of substrates;
a plurality of groups of electrodes disposed on at least one of the pair of substrates for applying an electric field to the liquid crystal layer;
a liquid crystal display part having a plurality of active elements connected to the electrodes;
drive means, supplied with display data from means for supplying data to be displayed, for driving individual pixels of the liquid crystal display part by applying a voltage corresponding to the display data to the individual pixels, the drive means including data emphasis means for comparing new display data supplied from the means for supplying data to be displayed with previous display data supplied from the means for supplying data to be displayed, and for emphasizing and converting the new display data to designated display data in response to a result of the comparison and the supplied data;
an illumination unit including a plurality of illumination areas for illuminating the liquid crystal display part; and
illumination control means for controlling an illumination start time and an illumination “
on”
time of each of the illumination areas of the illumination unit in response to a result of the comparison and the supplied data, which is correlated with data emphasis.

Abstract
A liquid crystal display apparatus is able to display high quality motion pictures with less after-image when displaying motion pictures and with less fuzzy images without making the response speed of the liquid crystal too fast. The display data emphasized excessively more than a changed value is written into the pixel having any change detected by comparison with the previous display data and its value is made to change excessively more than the value corresponding to its original display data, and then, according to the optical response of the liquid crystal, the lighting time and the lighting period of the light source are controlled for the individual areas of the illumination unit having plural areas.
