iPad 3 Rumor: New LED Back-Light System for Retina Display?
[ Technology]

You know those awesome, super high-resolution retina displays that are said to be coming to the next-generation iPads? Apparently, Apple needs to modify their back-lighting in order to support the new technology.

According to DigiTimes, LED Back-light unit vendors have given Apple two options on how to power their new devices. According to Taiwanese back-light unit manufacturers, Apple can either abandon the single LED light bar, or add LED chips to the current setup.

The high-resolution displays are reportedly going to top 2048×1536, and the current single LED light bar can’t quite handle it:

With the next-generation iPads expected to adopt LCD panels with resolutions higher than 2048 by 1536, the current single LED light bar designed for the iPad 2 has to be modify in order to maintain or strengthen the brightness of the panels, the sources explained.

One manufacturer has suggested designs that keep the single light bar, but add two LED chips. Another manufacturer suggests that Apple switch over to using dual-LED light bars.

According to the sources, Apple is likely to go with option B, and insert dual light bars into the upcoming tablet. Apparently, manufacturers have solved problems that were associated with dual light bar designs like heat production and battery depletion.

Last month, we heard a rumor that manufacturers of the high-resolution retina displays were having problems producing them in mass quantities. The iPad 3′s speculated 2048×1536 display will have a super-high pixel density, almost double that of the iPad 2.

The manufacturers, of course, can produce one of these screen no problem. The reported issue is producing them in high quantities.
