UDC is saying they have produced an ultra-thin flexible OLED display. The entire thing is less than 50 micrometer!  R.Ma from UDC says "We have chosen thin metal foils as the substrates for flexible displays because of their excellent thermal, mechanical and permeation barrier properties and good flexibility. Metal foils as thin as 25 mm have been used and planarization process has been developed. Another key challenge is to develop a flexible thin film permeation barrier. OLEDs degrade as a result of exposure to atmospheric oxygen and water. Working with Professor Wagner’s team at Princeton University, we have identified a flexible, highly impermeable barrier layer that is deposited from environmentally-friendly and inexpensive precursors in a single-chamber reactor. The lifetime of OLEDs encapsulated with the layers exceeds the industrial target of 1,000 hours and also the lifetime of conventionally sealed glass packaged OLEDs. Many materials are used in a flexible AMOLED: organ...

Last week marked the announce of the N85, the first Nokia Nseries device with an OLED screen. But first is first. What is an OLED screen?  OLED stands for organic light-emitting diode. (OLED) are screens that depends on very minute diodes that light up forming what we see, thus it doesn’t need backlight and this reduces the power consumption dramatically, while the traditional Liquid Crystal displays is made of pixels that require backlight, so the battery charges is drained faster, But that’s not it’s only pro, it’s also known for forming more realistic more lively photos that looks more real than the ones showed on LCDs and last but not least the Cost of production of OLED screens is much less than that of LCDs, cool, huh?! Guys over at Smape.com had the chance to review both the N85 and N96 and managed to compare the N96’s 2.8″ LCD screen with the N85’s 2.6″ OLED screen, and the results was stunning! Yes, there’s a huge difference between both screens, the N85’s screen rendered pho...
