Abstract

A controller device provides for local and global control of illumination color and intensity of a backlight. The controller architecture allows for optimization of an illumination surface and simultaneous sensing, analysis and control of each supported region of the surface to enable uniform light and color luminance output from the surface. The controller utilizes a temporal feedback mechanism which allows the use of monochrome sensors to control the color luminance output of the illumination system. The controller can be used during production of displays to set initial optimal conditions and also to continuously monitor and adjust backlighting during use of the display by the consumer. By using high frequency monitoring and control signals, as well as color blending, testing and correction can be conducted during use and beyond the threshold of perception of the human observer.
