BACKLIGHT DEVICE

摘要

The invention relates to a backlight (100) for illuminating e.g. LC displays (198) of LCD televisions. In order to enable a thin design of the backlight (100) and a high uniformity of the light emitted by the backlight (100) the invention suggest a design where transparent and diffusing masking elements (120, 121, 122) mask the individual light sources (110, 111, 112) and diffuses light back into the light guide (101). Absorbing elements (130, 131, 132) or retro-reflective elements are arranged so that they surround the light sources (110, 111, 112) in order to avoid generation of bright spots or rings around the light sources (110, 111, 112).
