Lighting Device for Liquid Crystal Screen |
摘要 |
A lighting device for liquid crystal display provides as output a polarized extended light flux. It comprises a light source 100 comprising a layer with high albedo A on the light emission surface SD(A), on which are stacked a quarter-wave plate 101 and a reflecting polarizer 103. This results in a light transmission gain of the order of 1+A, which makes it possible to produce displays with high luminance and low electrical consumption. Application to flat-screen displays.
