Display Power Modeling for Energy Consumption Control

As the most consuming devices in the video chain, it is necessary to master the power consumption of displays. However it necessitates to have a precise modeling of their power consumption. This paper proposes two approaches that outperform the state-of-the-art, to model the power consumption of emissive displays: first through the estimation of the display parameters from a theoretical RGBW model, then through two deep-based models agnostic of the display technology, that output either a global power value or a power map corresponding to an input image. All three modelings were made possible thanks to the release of DISPLAYPOWER2k, a large dataset of power consumption values for OLED displays.
