While the concept of a screensaver might not be all that novel in the PC world, apparently it's a new idea in TVs.

LG Display said Tuesday that the company's panels will now be able to use a few cached images stored in the TV's idle memory and will present them in Idle mode. The combination will save a bit of power, as well as give users something nice to look at while their TVs are not being used for video.

A single 47-inch TV model with the "Digital Photo TV" technology will be on display this week at the CES show in Las Vegas, said LG Display. Other technologies, including improved motion picture response time (MPRT) displays and eco-friendly displays, will be presented privately.

When in Photo mode, the TV uses just 10 to 15 percent of its normal power, according to LG Display. The panel's "idle memory" will be used instead of external memory - most likely limiting the number of images to just a few. However, cycling the images will also prevent image burn-in.
