Flexible poster combines OLED, LED

A Japanese company demonstrates how to combine LEDs and OLEDs to create a flexible poster.

While we're still waiting for OLED TVs to get more realistic prices, a Japanese company is moving on to making OLED-based posters for advertising.

The prototype, pictured above as a poster for Japan's Rakuten Eagles professional baseball team, uses both organic light-emitting diodes (OLED) and inorganic light-emitting diodes (regular LEDs) to create an image that looks like it's animated, according to Tech-On. The poster measures approximately 29 inches by 20 inches, and was created by Dai Nippon.

The LEDs are used for white backlighting behind a printed color image, and the OLEDs to create the text. Light is alternately emitted from areas of the LED, making parts of the poster seem to appear or disappear.

The material is slightly flexible, so it can be placed on a curved surface, and is resistant to vibration. Flexible displays are being developed in several different labs, and OLED has long been thought to be a great application since it doesn't use a rigid glass substrate the way LCD panels do.

A poster is a relatively new application, and one that might seem like a pricey and gimmicky way to do advertising. Gimmicky, perhaps, but Dai Nippon insists it's not that expensive: it's about 60 percent of the cost of a fluorescent lamp, and can run for 20,000 hours continuously.

The product isn't expected to be mass produced until 2010, but can be seen in person where it is currently on display at the Eagles' stadium in Sendai City, Japan until April 11.
