摘要: A system for color balancing within a liquid crystal flat panel display unit. The present invention includes method and altering the brightness of two or more light sources, having differing temperatures, thereby providing (LCD) unit given temperature range. embodiments operate both edge backlighting systems. In an embodiment, planar pipes are positioned, first over second, with air gap between. pipe is optically coupled to receive from source above predetermined range second below temperatures sources selected such that overall LCD can vary by driving voltages sources. another four used, each pipes. Another embodiment same temperature, associated one third, variable intensity, pipe. Yet single low profile wedge-shaped Separate extraction patterns be used on
