Color management for low light levels in OLED displays

The objective of the proposed research project is to develop a realistic color appearance model based on the human visual system’s functioning that addresses the issue of noise under low luminance levels. This will be incorporated into algorithms used in the color reproduction and retargeting algorithms of OLED displays. This model should give rise to reduced power consumption in OLED displays, while maintaining a high perceived quality of images. The project will also explore the effect of changing the white point to manage the circadian rhythm on OLED screens. The project will entail an evaluation and comparison of color gamuts on conventional LED and OLED displays, the development of solutions to use the OLED color gamut potential for power saving in mesopic and photopic vision conditions. The project will benefit the Alterview division of TandemLaunch in their development of color management solutions for mobile and tablet based computer displays.
