A collimator for use in a backlight liquid crystal display system

Abstract

\u3cp\u3eThe present invention relates to a system for lighting a display. The system comprises a light source (102), a collimator (120), and a liquid crystal display configured to receive a collimated light beam (126) and adapted to modulate the collimated light beam (126). The system further comprises a reflective sheet (110) having one or more pin holes (112) therein and having a reflective surface (116) facing the light source (102) and the other surface facing the collimator (120). The reflective sheet (110) is configured to transmit a part (114) of a light beam (108) to the collimator (120) and configured to reflect to a reflector (106) other parts (118) of the light beam (108).\u3c/p\u3
