led`s to be used in TV`s and Monitors for backlight

[TinderBox (UK)]

Hi.

I found a picture of the strip of led`s that are to be used in the upcoming models.

I wonder if they will just fit in the slot that the florecent tubes use to go in?

regards.

John.

This isn't in the future, this is happening now.

The high end LCD screens can already be had with LED backlighting.

The 15" Macbook Pro's already use them.

Dell also offers LED backlit screens on some of their laptops.

According to the Barco rep I spoke to at SIGGRAPH last week, LED backlighting is on its way to taking over, for both conventional displays and for higher-gamut and high dynamic range displays coming soon.

With 100lm/W LEDs becoming highly available and affordable, CCFLs have been overtaken in terms of efficiency. In addition, the driver circuitry is more simple (simple constant current buck/boost, instead of high voltage inverter), plus the durability and longevity of LEDs is much much higher than the CCFL. The only thing that CCFL probably has as an advantage right now is price, but I bet that will go away in a couple years as well.

I'd venture a guess that the Rebel's form factor is going to make it very popular in backlighting. I wouldn't be surprised if that was the indended application for the rebels.

NEC had LED displays on the market over a year ago - almost a 100% accurate colour reproduction and accuracy, although it's ugly as sin and super expensive.

One of thier initial advantages is that they have no mercury which makes for easier disposal.

Low cost implementations will use white LEDS, i.e. cheap displays, in car stuff, etc. Where quality is more important, i.e. higher end TVs, they will use RGB for perfect color and better gamut. You can also play games with the backlight, turning it on and off at the right time to increase contrast and effectively increase the on/off time of the LCD. Once the LCD elements become fast enough (<2msec ... very close now), we should start seeing displays that have no RGB matrix but are monochrome but with sequential backlight color using LEDs. That will increase the efficiency of current LCD displays by a factor of 3-4x or more. It should make for a more pleasing display as well.
