Title
(EN) DIGITAL DISPLAY SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ D'AFFICHAGE NUMÉRIQUE
Abstract
(EN) A system having a color filter (150) having first and second segments (151, 152). The first and second segments (151, 152) allow respective first and second wavelengths (121, 123) to pass through to a spatial light modulator (190). The first and second segments (151, 152) also reflect second and first wavelengths (123, 121), respectively. The reflected first and second wavelengths (121, 123) are recycled (127) and directed towards the color filter (150).
(FR) L'invention concerne un système ayant un filtre coloré (150) ayant des premier et second segments (151, 152). Les premier et second segments (151, 152) permettent à des première et seconde longueurs d'onde respectives (121, 123) de passer à travers un modulateur spatial de lumière (190). Les premier et second segments (151, 152) réfléchissent également des secondes et premières longueurs d'onde (123, 121), respectivement. Les première et seconde longueurs d'onde réfléchies (121, 123) sont recyclées (127) et dirigées vers le filtre coloré (150).
