Apple patent on LED backlights could spread tech

Apple LED backlight patent

Apple has sought to patent an LED backlighting scheme which could make the technology more practical for monitors in general, and possibly the company's own computers. While Apple notes that LED improves the color, life, brightness and power efficiency of monitors, the most recent 24-inch Cinema Display is said to have created unique design issues, demanding a way around problems with thermal control and area-to-perimeter ratios.

The Apple solution involves a collection of tiled LED lights, operating together in a "thermally and mechanically structurally integrated" matrix. The result is described as simple to implement and cost-effective, ideal for mass-producing larger displays. Apple may thus be ready to bring LED to different sizes of Cinema Display, or even the iMac, which does not use any form of LED backlighting at present.

    this is all good...

    ...but they also need to bring back a non-glossy finish as well.

    I'mhappy the tech makes things more efficient and better in the long run - but Apple still fails to understand that glossy only looks good on display in a shop to appeal to buying customers. It's not practical ina professional work environment under flourescent lighting.
