Apple considering Dual-LED Backlight for iPad 3 Retina Display

Apple plans to modify its LED backlight solutions for the display of the next generation iPad, in order to accomodate a much-improved screen resolution, according to Digitimes (opens in new tab).

Apple is expected to adopt LCD panels with a resolution higher than 2048x1536 pixels, which means that the existing single LED light bar integrated in iPad 2 has to be improved, otherwise the panels' brightness cannot be maintained or strengthened.

Sources from Apple's Taiwanese based backlight unit makers, reveal that vendors have offered two alternatives for Apple's display to be integrated in the upcoming iPad.

One suggestion panel makers have made is "to keep the light bar in a single-bar form factor but with two LED chips inside", according to Digitimes; the alternative would be the use of dual-LED light bars.

The source inside the Taiwanese supply chain suggested that Apple will probably accept the design with dual light bars. Especially since manufacturers declared they have resolved the issue with heat dissipation and battery consumption for this solution.

Previously it was suggested that manufacturers are facing real challenges with the mass production of the Retina Display for the iPad 3, expected to be released in Spring next year.
