Qualcomm is developing a technology that can bring videos to electronic paper, essentially adding more thrust to the technology.
In most e-paper displays, however, pixels switch on and off too slowly to display video, says James Cathey, vice president of business development for Qualcomm MEMS Technologies, based in San Diego. In contrast, pixels in the new Qualcomm display can switch in just tens of microseconds—fast enough to produce sharp video images. Cathey says that this ability to use the displays for video could make e-paper less of a niche technology and suitable for more mainstream multimedia displays for mobile devices like cell phones.
Electronic papers are highly power efficient, but the lack of response time has always been a disadvantage. Many firms are developing electronic paper products (Tech.co.uk) mainly for mobile technologies (IDG News Service | ComputerWorld).
Qualcomm's innovative technology is based on a principle similar to a film of oil on water that reflects several colors of the spectrum. Numerous cells sensitive to specific colors are turned on and off to display the images.
