Display Heaven
Samsung announced a 50" OLED screen last week. There's no word on pricing and availability yet, but I'm drooling already.
Forgot why OLED (Organic Light-Emitting Diode) was so much cooler than normal LCDs (what we see all over the place now), so I dug up my notes from the displays class I took, back in grad school.
Basically, LCDs are nonorganic, nonemissive light devices. They block/pass light reflected from an external light source or provided by a back lighting system. The back lighting system accounts for half of the LCD power requirements, which is the reason for their increased power consumption.
OLEDs are devices with carbon-based films placed between two electrodes (for positive and negative charges). When current is applied to OLED, the positive and negative charges recombine and generates electro-luminescent light. There's no need for backlighting in the packaging. And since it is emissive, that translates to better view angle. It's main advantages over LCDs are: more durable, increased brightness/contrast, lighter, thinner, faster response time, consumes less power.
"Your privates will become this small if you keep on using CRTs" -- The Samsung model points out the painfully obvious advantage of developing new devices with lower electromagnetic emissions. A MUST for engineers and geeks.
