Microsoft research propose a new OLED power consumption technique (which they call FingerShadow) that uses local-dimming for screen areas covered by user fingers. Because OLED pixels only consume power when lit, this is a clever way to save power when people interactive with their smartphones or tablets. According to Microsoft, they did a short study (10 users) and on average 11.14% of the screen is covered by fingers – which means FingerShadow can achieve a power saving of 5-22% (average 12.96%) with almost no overhead. Clever idea there Microsoft. Read more about Microsoft FingerShadow is a clever technique to save power on OLED mobile devices
