OLED display technology is gaining popularity among original equipment manufacturers (OEM). Production costs are decreasing, making this technology more readily available. OLED displays have a better contrast, no backlight and the ability to estimate the contribution of each pixel to the power of the display. This feature allows to experiment spatial algorithms to improve the image quality in relation to its power consumption. In this article we present a framework to evaluate the performance of spatial algorithms such asjust noticeable distortion and saliency maps on OLED displays. We introduce a comprehensive power model that takes into account each pixel value and the display screen brightness. We validate the effectiveness of this model by implementing a power reduction method based on power saving and perceptual quality metric.
