OLED TV
Previously I wrote about how computers need to have displays that can be rolled up or folded before they can begin to displace books and newspapers. That day may come sooner than we think.
According to this article in the Economist, Sony has started selling organic light-emitting diode (OLED) TV sets. OLEDs manage to combine the advantages of plasma (blacker black, angle view, clearer motion) with that of liquid-crystal (thinner, consumes less energy). Most remarkable of all, OLEDs can be made on thin and flexible materials, using ink-jet printing processes.
OLEDs have actually been around for quite some time, but life expectancy has been a major technical challenge. Sony claims that its OLED TV has a lifespan of 30,000 hours, which is only half of that of plasma displays and much less than that of LCDs. Nonetheless it’s a major improvement over earlier OLEDs which could only last for 5,000 hours.
