Q.
A. Before we discuss these different technologies, let's clear up the terminology.
LCD stands for liquid-crystal display. LEDs are light-emitting diodes, while OLEDs are organic light-emitting diodes.
LCDs and OLEDs are types of display. Technically, LEDs are not displays. LEDs are lights which are used in some displays as a backlight.
Traditional LCDs are backlit by CCFLs, cold cathode fluorescent lamps. These backlights are relatively bulky compared to LEDs.
CCFLs have other drawbacks, too. For example, they contain mercury, which is toxic. They also provide a limited spectrum of color.
So, some manufacturers are producing LED-backlit displays. You'll see these types of LCDs in some monitors and laptops. Some LCD televisions also use LED backlights. (Incidentally, some DLP TVs use LEDs, as do projectors.)
LED backlights certainly have their pluses. You'll get a brighter picture with a broader color spectrum. This is ideal for photographers and artists.
LEDs also use less power than CCFLs. That makes them particularly attractive in laptops. LED backlights are also thinner. And they don't contain mercury.
However, this is a next-generation technology. You're right; it's pricey. Until more people adopt it, prices will remain high
OLEDs are quite exotic for now. OLED displays contain a layer of organic material. A charge is applied to the material, resulting in a picture. There is no backlight; the material itself gives off light.
OLEDs have many advantages over other technologies. You'll get a bright, vibrant picture. The contrast ratio is phenomenal compared to LCDs. They also have a razor-thin form and consume minimal electricity.
There are drawbacks to OLEDs, of course. Their lifespan is limited in comparison to LCDs. However, a new technology could double OLEDs' lifespan. It would surpass that of LCDs.
Also, OLEDs are expensive. Sony is currently the only company selling an OLED display. The XEL-1 is a 3mm-thin, 11-inch television. It's a mere $2,500!
The future looks pretty good for OLEDs, though. They can be printed on surfaces. Since they're printed, they can be manufactured cheaply. I wonder how much of the XEL-1's price goes to research and development.
OLEDs are probably out of the question for you. However, an LED-backlight might be for you. That just depends on your needs�and your budget. Expect to pay about $1,000 more for an LED-backlit monitor.

LCD and LED monitors?
Q. I currently have an LCD monitor for my computer and I am getting a second monitor and it is LED. Will there be much difference and will they work well side by side. They both have DVI input.
Thanks for the answers, much appreciated. I will be getting the LED monitor.

A. A LED monitor is just an LCD monitor that uses a LED backlight instead of a fluorescent one. This helps alleviate the problem of poor color fidelity that LCD's suffer from, but does little to help poor black levels, response time, and viewing angles.
Hope it helps ! :-)
