Sony may have jumped the gun with its 10-inch OLED monitor, but we still think organic light-emitting diode may be the future of display technology. Well, it will be, as soon as someone figures out how to produce it for cheap. OLED is basically a thin film made up of organic compounds that come to life when an electric current passes through it. This allows devices based on the tech to be super-thin. And because it doesn't use a backlight, colors come out bright and sharp. It has a faster response time than LCDs. Though there are a host of burdens to overcome besides the cost of production—five-year average life spans, outdoor viewing—the possible applications are limitless.
