A novel driving scheme, smart power control SPC, is reported to reduce the power consumption of an AMOLED panel. SPC analyzes the range of the input data of each frame, calculates the optimum level of the power rail that drives the OLED, and varies the power rail voltage accordingly. As a result, a 30″ AMOLED consumes 20.1% less power when displaying the IEC 62087 standard movie clip.
