LG's Shuriken Self Refreshing Panel Aims to Improve Notebook Battery Life by Up to an Hour

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.

How many people have a static screen for any real length of time when the laptop is being used?MrSpadge - Wednesday, September 14, 2011 - link
Refresh rate is 60 Hz. A lot of it the screen images are static for a large amount of these 1/60 s intervals, as long as you're not gaming or watching movies.Mrs

On this very site my friend, i don't know about you but i don't have a per second clock on my desktop, nor am i moving my mouse around while i read articles, so at the very least if i'm reading a dense page, my CPU and GPU can effectively power down for up to a minute until my clock ticks over to display the next minute. instead of constantly firing out the same image to the lcd.Hrel - Thursday, September 15, 2011 - link
Oh man, I can hear the customer support calls already. "I turned off my computer but the screen is still on, and it's not moving, it's broken and I need a new one". Lol. Except for stupid people this looks awesome. Definitely gonna be on my next laptop. Wish this had come out years ago.
