Based on layers of organic molecules that are sandwiched together, OLEDs represent the most exciting development in display technology since the introduction of the LCD. OLEDs are already popping up on a few mobile devices. Eastman Kodak, for example, has released a digital camera-the EasyShare LS633-that fea- tures an OLED preview screen. Future OLED panels could find homes on products ranging from desktop and notebook PCs to PDAs to smart phones and a wide array of office and consumer appliances. In fact, the displays are thin and light enough to be plastered onto a wall like wallpaper or even sewn into clothing. Researchers, however, have yet to develop screens that are larger than a few inches in diameter at a price point that's even remotely competitive with LCD technology. "We're still a long way off from OLED in a laptop," says Sam Bhavnani, a mobile computing analyst at ARS, a technology research firm located in La Jolla, California. "You might start to see 10-inch or maybe a 12-inch [screen] in the beginning of 2005, at best," he says. Meanwhile, engineers at the University of Toronto are among many researchers worldwide working on developing a flexible OLED technology. The school's engineers recently became the first Canadian team to construct a flexible organic light-emitting device (FOLED), a technology that could lay the groundwork for future generations of bendable television, computer, PDA, and mobile phone screens. "It opens up a whole new range of possibilities for the future," says Zheng-Hong Lu, a professor in the University of Toronto's Department of Materials Science and Engineering.
