Title (EN) SYSTEMS FOR AND METHODS OF AMBIENT-LIGHT REDUCTION IN OLED DISPLAY SYSTEMS AND LCD SYSTEMS
(FR) SYSTÈMES ET PROCÉDÉS DE RÉDUCTION DE LA LUMIÈRE AMBIANTE DANS DES SYSTÈMES D'AFFICHAGE DELO ET DES SYSTÈMES LCD
Abstract:
(EN) Systems and methods for ambient-light reduction in display systems with OLED or LCD based displays are disclosed. The base display is interfaced with an ambient-light-reducing (ALR) structure to form the display system. The ALR structure includes an ALR component. The ALR component can be a photochromic component or a fixed neutral-density component. The ALR structure attenuates incoming ambient light as well as outgoing redirected ambient light that is generated within the base display and is then emitted from the display system into the ambient environment. This increases the ambient contrast relative to that of the base display alone.
(FR) L'invention concerne des systèmes et des procédés de réduction de la lumière ambiante dans des systèmes d'affichage dotés d'affichages à base de LCD (affichage à cristaux liquides) ou de DELO (diode électroluminescente organique). L'affichage de base est en interface avec une structure de réduction de la lumière ambiante (structure ALR) pour former le système d'affichage. La structure ALR comprend un composant ALR. Le composant ALR peut être un composant photochromique ou un composant de densité neutre fixe. La structure ALR atténue la lumière ambiante entrante ainsi que la lumière ambiante redirigée sortante qui est générée à l'intérieur de l'affichage de base et est ensuite émise par le système d'affichage dans l'environnement ambiant. Cela augmente le contraste ambiant par rapport à celui de l'affichage de base seul.
