LG's Shuriken Self Refreshing Panel Aims to Improve Notebook Battery Life by Up to an Hourby Anand Lal Shimpi on September 14, 2011 1:26 PM EST
We've been hearing about self refreshing panels for years now and today Intel demonstrated one such panel using LG's Shuriken panel. The premise is simple: there's a small amount of memory contained within the panel itself that stores a copy of the current frame being displayed on the screen. If the screen is static, the display is fed from its internal frame buffer rather than from the PC's GPU allowing the PC (both CPU and GPU) to go to sleep. In the demonstration Intel showed power savings of 500mW, which could add up to an extra hour of battery life depending on the usage model and notebook.
The demonstration didn't include any quick animations but even when watching a photo slide show the Shuriken was able to run entirely off of its own internal frame buffer. Check out the demo in the video below. Intel expects to see displays with panel self refresh available in notebooks within the next 2 years.
