Power Saving and Optimization of OLED Displays for Better System Design: A Survey

OLED displays are very popular among current system designs due various advantages like picture quality, response time, lightweight and lower thickness, etc. Still, one of the major design challenges when dealing with these displays is the amount of power consumed. In battery-operated computing devices, the display consumes almost 50% or more of the total system power. Though many methods are available to reduce power consumption like lowering the refresh rate, panel self-refresh, or adaptive dimming, still designers are looking for more room for optimization. As the design philosophy of mobile devices is directed towards extending the battery life, the methods to save power from the OLED display hold great relevance. This paper surveys the latest research and advancements on the topic.
