Abstract: Methods and devices employing circuitry for dynamically adjusting bandwidth control of a display interface are provided. The display interface or image content is dynamically adjusted to support both high-speed image data (e.g., 120 Hz image data) and lower-speed content (e.g., 60 Hz content). For example, in some embodiments, additional pixel pipelines and/or processing lanes may be activated during the rendering of high-speed image data, but not during the rendering of low-speed image data. Additionally or alternatively, high-speed image data, but not low-speed data, may be compressed to render high-speed content over an interface that supports only low-speed content.

Abstract translation: 提供了采用电路动态调整显示接口的带宽控制的方法和设备。 动态调整显示界面或图像内容以支持高速图像数据（例如，120Hz图像数据）和较低速度内容（例如，60Hz内容）两者。 例如，在一些实施例中，可以在渲染高速图像数据的过程中激活额外的像素管线和/或处理通道，但在渲染低速图像数据期间不激活附加的像素管线和/或处理通道。 另外地或可选地，高速图像数据（而非低速数据）可以被压缩以通过仅支持低速内容的接口呈现高速内容。

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.
