Filed:

Jan 24, 2006

Appl. No.:

11/338315

Inventors:

Peter A. Zagar - Hartford WI, US
Frederick C. Ellner - Glendale WI, US
Hans C. Hansen - West Bend WI, US

Assignee:

Astronautics Corporation of America - Milwaukee WI

International Classification:

H05B 41/38

US Classification:

315291, 315307, 345 83, 345102

Abstract:

A color balanced solid-state backlight provides feedback control of each color using a single photodetector by imposing a modulation pattern on the solid-state lamps revealing individual colors to the photodetector. The photodetector signal provides feedback controlling color balance over a small range of instantaneous brightness less than larger range of average brightness of the display to provide for accurate color balance throughout a large range of average brightnesses.
