A great percentage of future gadgets will depend on OLEDS so it’s time we provided a little insight into this technology. Organic Light Emitting Diodes were truly born in 1990, when years of research produced a highly efficient polymer that emitted green light. Layers of organic semi conductors are sprayed onto a screen (or polymer).
An applied voltage causes electrons to move into the emissive layer, leaving the conductive layer full of ‘electron holes.’ The electrons and their holes recombine in the emissive layer and this causes light to be given out. The emitting layer contains different compounds which give out red, blue and green light.
Combined, these three compounds can give out around 16 millions different colours. That’s pretty impressive, to say the least.

Do you remember how much fun rubber pencils were when they were all the rage? OLED screens are just as flexible since the technology can be printed onto almost anything so we can even have ultra-thin or transparent displays too. (This makes the screen very lightweight; another advantage.)
The best part is that these futuristic screens are environmentally friendly. The OLED components are green. The screens are very bright but their power consumption is so low that this technology is the future of lighting too. Imagine pairing OLED devices with photovoltaic technology (solar power). The anticipation to see how Green technology really gets is spine-tingling.
So without further delay, let’s see what the century has dished up so far.

(i) Google Vision
The retractable, transparent screen is only the portal of all the information Google plans to bring you. Advanced image recognition will tag whatever you aim the device at. When on vacation, you’ll no longer be the ignorant tourist since Google Vision will identify any landmarks you happen to point at too. The global positioning system will let you use this device to navigate as well.


(ii) OLED lighting
There really isn’t much to say here. They’re environmentally friendly and we can look forward to a whole range of creative OLED lights since the technology can be printed onto a vast number of surfaces. There’s almost nothing out on the market now but Philips lets you order while OLED panels to use or play about with.

(iii) Samsung Notebook
Feast your eyes on the world’s first OLED laptop.
The 12-inch display is razor thin and the whole laptop only weighs a kilogram.
The prototype does have people wondering about the mouse pad, strange keypad feel and battery space but perhaps by the time this is commercialised Samsung’s end product will be something that is completely satisfactory.
