“On May 28, 2009, the US Patent & Trademark Office published an Apple patent (United States Patent Application #20090135583) that generally relates to display systems, and more particularly to a desktop display system with a distributed LED backlight,” Jack Purcher reports for MacNN.
“Apple’s iPod, MacBook, MacBook Pro, MacBook Air and Cinema Display currently use LED based displays which provide substantial improvements over LCDs in brightness, energy efficiency, color range, life expectancy, durability and robustness. Yet creating the 24″ Cinema Display was no small task, as larger LED display configurations create area-to-perimeter ratio difficulties,” Purcher reports.
“Apple’s patent greatly details their integrating a plurality of tile LED light sources into a thermally and mechanically structurally integrated distributed LED tile matrix backlight light source. At the end of the patent, Apple states that their new distributed LED backlight system has provided for a straightforward, cost effective and uncomplicated process that is readily suited for efficiently and economically manufacturing large size display devices,” Purcher reports.
