So I was looking at the customization options for the Dell Studio XPS 13, and noticed that the LED backlit screen was more expensive. Why is that? I thought that LEDs were supposed to be cheaper.

Yeah, I understand that. I guess it has to do with manufacturing; since LEDs for now only emit one color, so they have to produce backlights with the individual LEDs for the color.

What?

Do backlights even need to emit more than one color? Isn't having white enough? Is there even such a thing as a non-white backlight?

Its probably referring to Organic LED's as opposed to old style LED's. OLED is really brand new technology, the first OLED television was made by Sony last year, was 10 inches and cost a fortune, the equivalent of a 40" 1080p plasma. Ive seen laptops with OLED displays, like the Macbook air, and yes it saves battery and has a much more vibrant rich display then normal LCD TFT displays.

More info on OLED here http://en.wikipedia.org/wiki/Organic_light-emitting_diode


Edit: heres a link to that TV I was talking about. http://www.sonystyle.com/webapp/wcs/stores...552921665327724

well....... I am not sure what you are talking about specifically, the are two things it could be

1) OLED display, a display comprising entirely of millions of tiny LEDs
2) LED backlit LCD, this is a normal LCD, but instead of a florescent backlight, it has hundreds of LEDs, this saves power, and allows the backlight to be dimmed locally to get "blacker blacks"
