CA 2581743

A liquid crystal structure (200) comprising first and second reflective regions (214a, 214b, 214c) arranged to reflect respective first and second colours. The first and second reflective regions (214a, 214b, 214c) are disposed transversely to the direction of reflection (R). Each region includes a reflective back area and a selector (210) controllable to control light reflected from the region. Furthermore, a controllable reflector (212) is superposed over the reflective region in the direction of reflection (R) and controllable to transmit or scatter incident light.

L'invention porte sur une structure de cristaux liquides comprenant une première et une deuxième zone réfléchissantes conçues pour réfléchir respectivement une première et une deuxième couleur. La première et la deuxième zone réfléchissantes sont placées transversalement par rapport à la direction de réflexion. Chacune des zones comporte une surface arrière réfléchissante et un sélecteur réglant la lumière réfléchie par chaque zone.
