OLED(Organic Light-Emitting Diode) displays



Yeah, we hear you. Another year, another promise that OLED screens are going to take over. Haven't we heard it all before? Except this time it could be true.
Google's Nexus phone has just launched with an OLED screen, and by all accounts it makes the handset almost – say it in hushed tones – more desirable than the iPhone. Brighter colours, sharper resolutions, darker blacks, whiter whites; why is this OLED technology so superior?
Put simply, it's because instead of filtering the light from a white or blue lamp behind the screen, each pixel in an OLED panel produces its own light. You don't have to be an optometrist to see why this is better, but it is much more expensive to produce.
Still, it also means OLED screens are much thinner than backlit ones, for obvious reasons, and while you may not be using an OLED PC monitor by the end of the year there are a lot more laptops with the technology arriving.
