Abstract

Official abstract text for this publication.

A light source portion includes a plurality of back lights provided corresponding to respective regions obtained by virtually dividing a liquid crystal panel screen into a plurality of parts, the back lights have a light emission intensity controlled based on a light emission intensity value and have ON and OFF operations controlled in response to a light emission driving signal, and the light emission driving signal is constituted to sequentially turn ON the plurality of back lights synchronously with a stereoscopic image signal and to turn ON the plurality of back lights at the same time in a predetermined timing, and is constituted to individually control a light emission period for the plurality of back lights based on image information about the stereoscopic image signal.

First claim

Opening claim text (preview).

What is claimed is: 1. A stereoscopic image display device comprising: a liquid crystal panel portion to be horizontally scanned sequentially from an upper part to a lower part of a liquid crystal panel screen based on a stereoscopic image signal, thereby varying a transmittance of light depending on a gray scale of said stereoscopic image signal; a light guiding portion provided on a back face side of said liquid crystal panel portion for receiving light from a light source por…
