PARVAI — HVS aware adaptive display power management for mobile games

Displays are one of the major system energy consumers in smartphones. Power consumption of Organic Light-Emitting Diode (OLED) displays have direct relationship with the colour and intensity of the contents being displayed. Games are one of the most popular smartphone applications that consume relatively more resources and power. In this paper, we present Human Visual System (HVS) aware algorithms and techniques to reduce OLED display power consumption up to 45% while retaining the perceived quality of game content. We have implemented and evaluated our solution in the game Quake III and its Android port Kwaak3.
