OLED (Organic Light Emitting Diode) technology has already been adopted in many modern smart mobile devices, including cellphones, tablets, laptop etc. However, the power dissipation of displays in some applications like real-time video streaming, significantly limits the smart mobile devices' battery life and influences user experience. In this work, we applied a set of power management techniques that based on the dynamic voltage scaling (DVS) to minimize the power consumption of OLED display. Circuit inventions are also introduced to enable the local voltage scaling of AMOLED display panel while the human vision reception criteria can still be met. We then apply the DVS-based power management techniques to online video streaming, which is the most energy-hungry application of mobile devices: For any known type of mobile devices with AMOLED displays, the DVS power management scheme of a specific video stream can be pre-analyzed and shared on network, i.e., the Cloud or local party that provide the video. The DVS scheme can be downloaded in the real-time simultaneously when the video is broadcasted to the end users. By doing so, the power and computation overheads of DVS optimization are amortized among all the users, achieving a high service quality. Furthermore, the optimization can be executed locally (at user end) and shared by all the users. © 2012 ACM.
