Organic light-emitting diode - OLED - Admin_phpbb3_import1 - 02-23-2009
An Organic Light Emitting Diode (OLED), also Light Emitting Polymer (LEP) and Organic Electro Luminescence (OEL), is any Light Emitting Diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. The layer usually contains a polymer substance that allows suitable organic compounds to be deposited. They are deposited in rows and columns onto a flat carrier by a simple "printing" process. The resulting matrix of pixels can emit light of different colors.
Such systems can be used in television screens, computer displays, small, portable system screens such as cell phones and PDAs, advertising, information and indication. OLEDs can also be used in light sources for general space illumination, and large-area light-emitting elements. OLEDs typically emit less light per area than inorganic solid-state based LEDs which are usually designed for use as point-light sources.
A significant benefit of OLED displays over traditional liquid crystal displays (LCDs) is that OLEDs do not require a backlight to function. Thus they draw far less power and, when powered from a battery, can operate longer on the same charge. Because there is no need for a backlight, an OLED display can be much thinner than an LCD panel. Degradation of OLED materials has limited their use.

that's great, the future is approaching. I can't wait to hold a cell phone like this in my hand. I'm usually behaving very uncareful with cell phones and they break quickly. This one I can drop hundreds times and nothing will happen to it!

The innovation is great. It is a half step to future, since the basic idea was established. Science can also use this technology for medical purposes, for example for examining organs of the body, as the OLED is flexible and can penetrate places that up to the moment were unavailable for the medicine researching.

I remember recently Samsung boasted they can make their phones half the thickness of paper. Do you think it's possible? I mean a paper thickness is probably 0.3 mm.

I don't know about phones half the thickness of paper but the new samsung omnia hd with oled display looks very impressive.

The first phones with elastic OLED displays that would make it possible to control the phone only via touch-screening will leave no chances for other phones to survive on the market. They will never break, so it's very convenient for people that are not careful with such gadgets.

OLED display gives better and more natural colours. As I can see, this phone has 16 million colours (16 bits), which is great. Old phones that have 16 million colours couldn't boast about the true colour showed on the screen, since it shrank the diapason of colours, but the OLED seems to be giving the true colour.

Impressive device. I saw that only in movies. Like 15 years ago we couldn't imagine that the future is so near and what we see in movies is soon likely to become reality. Great!

I think we should relax, as we're not gonna see these items selling on the market in the near future. Yet, it is worth of waiting, OLED colours are so vivid. Prepare to throw your big TVs (even LCDs) away. OLED products are gonna eat you alive.

Small-molecule OLED are definitely the winners

It is a very interesting inovation! I belive such screens will be spread a lot in a close future
