Abstract

Algunas modalidades de un aparato ilustrativo pueden incluir una pantalla, un primer difusor controlable superpuesto a la pantalla, el primer difusor controlable puede operarse selectivamente para difundir luz en una primera dirección de difusión, y un segundo difusor controlable superpuesto a la pantalla, el segundo difusor controlable puede operarse selectivamente para difundir luz en una segunda dirección de difusión sustancialmente perpendicular a la primera dirección de difusión. En algunas modalidades, un método ilustrativo puede incluir emitir un haz de luz desde un dispositivo emisor de luz; polarizar linealmente el haz de luz; pasar el haz de luz a través de materiales de LC y birrefringentes; y aplicar una tensión para alterar la polarización del material de LC, de un primer estado que hace que la luz se difunda en una primera dirección al pasar a través del material birrefringente, a un segundo estado que hace que el haz de luz se difunda en una segunda dirección al pasar a través del material birrefringente.
