Epson shows 0.47-inch, 800x600 EVF panel

Epson has began producing a small, high-temperature polysilicon LCD panel that is just 0.47 inches in diagonal size and has an extremely dense 800x600 resolution. The panel is meant for use in the electronic viewfinders (EVF) of some digital cameras and is crisp enough to replicate an actual optical eyepiece. Unlike competing products that display RGB colors in sequence, the new example doesn't produce color breakup. This is evident as an iridescence in the outlines of objects when panning or looking away from the screen at a certain speed.

Panasonic's Lumix G1 digital camera suffers from this phenomena with its own EVF, Epson is quick to point out. Epson's LCD panel shows all RGB colors simultaneously by using a color filter.

Epson plans to put the new EVF screen into production in the near future and has plans for a 2.07-megapixel, full HD version in the near future at the request of camera manufacturers. These weren't named but may include Panasonic, Olympus and others that can't use optical viewfinders. [via TechOn]
