Sony introduces world's first 16.7 million color flexible OLED display

Flexible displays while a novelty today, may prove to be extremely useful in many industries a few years from now. Many of the big display manufacturers are developing flexible displays such as flexible e-paper.

A number of companies working on delivering E-paper technology to the masses. LG.Philips demonstrated a 14.1-inch flexible display capable of 4,096 colors. Another company, Nempotec, demonstrated a similar display that same day.

This week Sony announced yet another world first: a flexible organic LED (OLED) display that is capable of displaying 16.7 million colors. Current OLED technology is only capable of up to a few thousand colors. Samsung and LG.Philips have flexible OLED displays too, but they are only capable of 262,000 and 16,000 colors respectively.

Sony's display is only 0.3mm thick. Since OLEDs are their own light source -- they don't require backlighting -- and manufacturers can produce extremely thin substrates. The display is 64mm in diameter, has 160x120 pixel resolution and sports a 1000:1 contrast ratio.

However, don't expect these flexible OLEDs to replace e-paper anytime soon. OLED displays require power to retain an image, whereas e-paper displays only use electricity when change is needed.  Thus, the power draw on e-paper devices is still considerably lower than OLED.

Red and Green last the same as LCD or plasma, blue is about half that but they are working on it.

Actually they've made good advances in the blue led, which iirc had a considerably shorter lifespan than the others.

I doubt it take very long before this technology matures. The market is there I think, especially with all the green initiatives out there considering the power savings involved.

Plus, hey they look very nice.
