Display backlighting system |
摘要 |
A display back lighting system (100) includes a light pipe (106) that is mounted above a printed circuit board (102) and below a liquid crystal display (108). The backplane (112) of the light pipe has a surface area adapted to accommodate the liquid crystal display. The backplane of the light pipe is substantially perpendicular to a light emitted from a light source (104) mounted on the printed circuit board. An entrance lens (114) on the light pipe receives light from the light source and directs the light towards a reflecting lens (116). The reflecting lens optimally has an elliptical shape that reflects light from the entrance lens toward the backplane of the light pipe. In this manner, a backlight is provided for a liquid crystal display.
