Abstract: Technologies for low-power display refresh standby include a computing device with a display such as an LCD panel. The computing device may include a system-on-a-chip (SoC) with a processor, I/O subsystem, display controller, and memory. When the computing device determines that a display image is static, the computing device enters a low-power display refresh standby mode, powering down unneeded components of the SoC such as processor cores, peripheral devices, and memory other than a dedicated display buffer. The display controller may access the dedicated display buffer via the I/O subsystem and output the image to the display. The computing device may power down the I/O subsystem and the dedicated display buffer when a display controller FIFO is full of image data, and periodically power on the I/O subsystem and display buffer to fill the display controller FIFO. Other embodiments are described and claimed.

Abstract translation: 用于低功率显示刷新待机的技术包括具有诸如LCD面板的显示器的计算设备。 计算设备可以包括具有处理器，I / O子系统，显示控制器和存储器的片上系统（SoC）。 当计算设备确定显示图像是静态时，计算设备进入低功率显示刷新待机模式，为诸如处理器核心，外围设备和专用显示缓冲器之外的存储器的SoC的不需要的组件供电。 显示控制器可以通过I / O子系统访问专用显示缓冲区，并将图像输出到显示器。 当显示控制器FIFO充满图像数据时，计算设备可能会关闭I / O子系统和专用显示缓冲区，并周期性地打开I / O子系统和显示缓冲区以填充显示控制器FIFO。 描述和要求保护其他实施例。
