Abstract

Large liquid crystal display (LCD) technology is being widely used in every corner of our modern life, ranging from personal laptops to flat-panel televisions. Among all the components in an LCD display system, the backlight panel is the dominant power consumer, irrespective of lighting technology or class. In this paper, a saliency-based field-programmable gate array accelerator for revolutionary LCD power management is proposed that allows dynamic modulation of the different zones of the backlight panel. This hardware accelerator-based system is capable of processing a high-definition video stream in real-time and uses less than 50% of the power that a normal LCD display system consumes, with minimum overhead. We also compare our proposed approach with other state-of-the-art power-aware methods and show numerous advantages using our data-driven strategy.
