Large scale liquid crystal structures
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.
The invention relates to a liquid crystal (LC) structure for example for a liquid crystal display, and use of such a structure in billboards or other information displays used in high or variable ambient light environments e.g. machine instrumentation, enunciator boards, military hardware controls or other large-scale displays viewable from a distance.
