COLOUR SEQUENTIAL ILLUMINATION SYSTEM |
摘要 |
A colour sequential illumination system, such as, for example, a backlighting system for a liquid crystal display (LCD), comprises lamps for emitting blue, red and green light. The red and green light is provided by lamps including fluorescent dyes having optical decay times similar to a phosphor material used to provide the blue light. In this manner, the blue, red and green emissions can be fully synchronised with electrical signals used to energise the lamps, enhancing colour range and colour quality. Furthermore, if the fluorescent dyes are carried in plastics materials, then trapping and concentration of the light generated may also be achieved, providing enhanced brightness fox the LCD for a given power input.
