Title
(EN) INTEGRATED MODULATOR ILLUMINATION
(FR) ECLAIRAGE D'UN MODULATEUR INTEGRE
Abstract
(EN)
A spatial light modulator includes an array of elements (204) to modulate light in accordance with image data. The modulator has a display panel having first and second surfaces arranged adjacent to the array of elements such that the second surface is directly adjacent the array of elements to allow a viewer (214) to view an image produced by modulation of light. The modulator may also include a light source (216) to provide light to the display panel and illumination dots (208) on the first surface of the display panel to reflect light from the source to the array of elements.

L'invention concerne un modulateur spatial de lumière, qui comprend un réseau d'éléments (204) servant à moduler la lumière selon des données d'image. Le modulateur comprend un panneau d'affichage présentant une première et une seconde surfaces jouxtant le réseau d'éléments pour permettre à un observateur (214) de visualiser une image produite par modulation de la lumière. Le modulateur peut également comprendre une source lumineuse (216) qui éclaire le panneau d'affichage, et des points lumineux (208) présents sur la première surface du panneau d'affichage pour réfléchir la lumière de la source au réseau d'éléments.
