Trade-off between luminance and color in RGBW displays for mobile-phone usage

By Wang Lili, Tu Yan, Chen Li, C Teunissen and IEJ Ingrid Heynderickx


\u3cp\u3eCompared to RGB displays, RGBW displays enable higher luminance levels at equal power consumption. One of their drawbacks, however, is their reduced color saturation. In this paper, the trade-off between luminance and color saturation is evaluated in a perception experiment for several algorithms to map RGB input to RGBWpixel data. It is shown that the optimal mapping algorithm is affected by image content.\u3c/p\u3
