Abstract: The disclosure describes procedures for dynamically employing a variable refresh rate at an LCD display of a consumer electronic device, such as a laptop computer, a tablet computer, a mobile phone, or a music player device. In some configurations, the consumer electronic device can include a host system portion, having one or more processors and a display system portion, having a timing controller, a buffer circuit, a display driver, and a display panel. The display system can receive image data and image control data from a GPU of the host system, evaluate the received image control data to determine a reduced refresh rate (RRR) for employing at the display panel, and then transition to the RRR, whenever practicable, to conserve power. In some scenarios, the transition to the RRR can be a transition from a LRR of 50 hertz or above to a RRR of 40 hertz or below.

Abstract: Methods and systems for managing power are described. In one embodiment of a method, a DC input voltage from an AC mains to DC converter, inputted to a DC to DC converter, is adjusted lower while maintaining substantially constant DC output voltage from the DC to DC converter in order to improve power effi ciency.

Abstract translation: 本公开描述了在诸如膝上型计算机，平板计算机，移动电话或音乐播放器设备的消费电子设备的LCD显示器上动态地采用可变刷新率的过程。 在一些配置中，消费电子设备可以包括具有一个或多个处理器的主机系统部分和具有定时控制器，缓冲电路，显示驱动器和显示面板的显示系统部分。 显示系统可以从主机系统的GPU接收图像数据和图像控制数据，对所接收的图像控制数据进行评估，以确定在显示面板上使用的刷新率降低（RRR），然后在切实可行的情况下转换到RRR ，以节省权力。 在某些情况下，过渡到RRR可以是从50赫兹或更高的LRR到40赫兹或更低的RRR的转换。
