LED-Backlit Apple and HP Laptops in Q2?

Laptops from Apple and HP might use LEDs as a backlight source starting in the second quarter of this year. These LED backlights distribute backlight more evenly than the cold cathode florescent backlights used in laptops today, and also offer a higher range of colors.


We've tested LCD monitors using LED backlight, and their increased color saturation gives the screen noticably more-intense colors—so much so that they look almost unnatural at first. This technology has been around for a while. In fact, we tested an IBM monitor with an LED backlight four years ago. However, LED backlights haven't been adopted in laptop screens thus far because of fears of high power consumption.

What about higher prices? If the cost of these fancy screens raises the prices of notebooks by too much, this tech will probably not hit the mainstream for a while. There's no word on which models will be upgraded with the LED technology.

A single LED requires next to no power, if it's just your standard run of the mill LED.

But to EVENLY light a display, usually requires many LEDs placed all over the display area, or possibly some kind of optical distribution, which would then require a high power LED.

When you are talking a lot of LEDs, it can get expensive. If you need high power LEDs, they are expensive as well.

That is the main reason for cost and power efficiency. Only recently, has the efficiency of high power LEDs started to compare with other light sources.

I'm looking forward to this technology, because generally, the lifetime of LED technology is almost twice that of CCFL (100K hours, versus 60K hours), the backlighting will be more even, better color rendering, hopefully less backlight leakage (problem with some LCD TV's), etc.
