Abstract

Active matrix organic light-emitting diode (AMOLED) display is an emerging technology that has been widely used in mobile devices. It incorporates a varying power-demand character, which is particularly inefficient for displaying bright colors. This paper presents a power-saving scheme for AMOLED display based on the pixel dimming transformation. Initially, the proposed method suppresses luminance and reconstructs colors of any overexposed region. Then, each pixel is transformed using coefficients derived from the SSIM metric, of which the set point is determined from the prior image. Weighted coefficients are employed specifically for high-frequency visible spectra. According to the measurements of three datasets on a smartphone with AMOLED display, up to 75% of displaying power can be reduced with mean visual saliency index of 0.955.
