The transition which began last year appears to be coming to an end with Apple's remaining notebooks set to receive LED back lit units by 2009.
According to the Chinese-language Economic Daily News (EDN) Apple plans to use back light unit maker (BLU) Kenmos Technology to help complete a promise Apple made last year to transition all notebooks to LED-lit displays.
Since Steve Jobs' open letter declaring Apple's aim to become "greener" the company made LED-lit display standard on the 15-inch MacBook Pro, and an option on the 17-inch MacBook Pro, but in a storming move for the industry introduced the MacBook Air with the brighter and more power efficient LED backlit technology.
