Abstract
En 中文
Organic Light-Emitting Diode (OLED) technology is regarded as a promising alternative to mobile displays. In this article, we introduce the design, algorithm, and implementation of a novel framework called CURA for quality-retaining power saving on mobile OLED displays. First, we link human visual attention to OLED power saving and model the OLED image scaling optimization problem. The objective is to minimize the power required to display an image without adversely impacting the user’s visual experience. Then, we present the algorithm used to solve the modeled problem, and prove its optimality even without an accurate power model. Finally, based on the framework, we implement two practical applications on a commercial OLED mobile tablet. The results of experiments conducted on the tablet with real images demonstrate that CURA can reduce significant OLED power consumption while retaining the visual quality of images.
