Title
(EN) IMAGE DISPLAY SYSTEM
(FR) SYSTEME D'AFFICHAGE D'IMAGE
Abstract
(EN)
An image display system, e.g. for projection type displays, has an electrically addressed spatial light modulator or EASLM (1) and an optically addressed spatial light modulator or OASLM (5). An image formed on the EASLM (1) is transferred to a part of the OASLM (5) by an image transfer means (3) and the image produced by the OASLM (5) is formed from a plurality of successive images formed by the EASLM.
(FR)
La présente invention concerne un système d'affichage d'image, par exemple pour des affichages de type projection, comportant un modulateur spatial de lumière à adressage électrique, ou EASLM (1), et éventuellement un modulateur spatial de lumière à adressage optique, ou OASLM (5). L'image formée sur l'EASLM (1) est transférée à une partie de l'OASLM (5) au moyen d'un dispositif de transfert d'image (3), l'image produite par l'OASLM (5) étant formée à partir de plusieurs images successives formées par l'EASLM.
