显示功耗通常是许多便携式设备总体功耗预算中最重要的贡献者。传统上，液晶显示器（LCD）的功耗最小化主要集中在技术和电路设计上。在本文中，我们采用正交方法，并介绍了几种用于LCD动态电源管理的纯软件技术，这些技术不需要对现有LCD及其控制器进行任何硬件更改。节能效果显著：在原型可穿戴系统平台上测量的总系统功耗从40%（没有可感知的图像退化）到60%（有明显但可容忍的退化）。
Display power consumption is often the most significant contributor to the overall power budget for many portable devices. Traditionally, liquid crystal display (LCD) power minimization has focused on technology and circuit design. In this paper we take an orthogonal approach, and we introduce several software-only techniques for LCD dynamic power management, which do not require any hardware changes on existing LCDs and their controllers. The power savings achieved are significant: from 40% (with no perceivable image degradation) to 60% (with significant, but tolerable degradation) of total system power, measured on a prototype wearable system platform.
