One‐dimensional (1‐D) Dynamic supply Voltage Scaling (DVS) scheme with image distortion compensation is proposed for reducing the static power consumption in AMOLED displays. A hybrid simulation platform combining MATLAB and circuit simulator HSPICE was built for the study. By applying the DVS scheme to both static images and video streams, it is shown significant power saving can be achieved (>40% for the test video streams) without sacrifice of the image or video quality.
