Konica Minolta claims it has developed an OLED (Organic Light-Emitting Diode) which offers the world's most efficient electric light source. Their new OLED technology runs at 64 lumens/W and has a brightness of 1000 cd/m2.

The company said the next-gen OLED has an expected lifetime of 10,000 hours. Because the device can emit light of varying color tones to simulate tungsten electric bulb or fluorescent light, it can be used in various general lightning applications including backlight for handset displays.

OLED is a thin-film, light-emitting diode (LED) designed primarily as picture elements in practical display devices. OLED displays do not require a backlight to function and consume less energy and operate longer on battery.
