N2 - Recently power management of display modules has become important for handheld systems. In this paper, we observe the interaction between the LCD, main consumer of the power in handheld systems, and the CPU. We propose an efficient method which reduces power consumption of the handheld system by controlling the voltage and frequency of the CPU to reduce display power. The experimental result on Mainstone II with PXA270 shows that the proposed mechanism reduces power consumption of the system by 41% and 15% for multimedia applications and web applications, respectively, when compared to the conventional DVS (Dynamic Voltage Scaling) scheme.
