Title
(EN) ENHANCED QUANTUM DOT ON COLOR FILTER LCD
(FR) POINT QUANTIQUE AMÉLIORÉ SUR UN LCD À FILTRE COLORÉ
Abstract
(EN)
A quantum dots on color filter (QDCF) LCD apparatus having certain combinations of enhancement features that enhance contrast ratio by eliminating or minimizing high angle incident light within the LCD stack is disclosed.
(FR)
L'invention concerne des points quantiques situés sur un appareil LCD à filtre coloré (QDCF) dont certaines combinaisons de caractéristiques d'amélioration améliorent le rapport de contraste en éliminant ou en réduisant au minimum la lumière incidente à angle élevé à l'intérieur de la pile de LCD.
