iPad 3 Retina Display: Apple Considering Dual LED Light Bars

• 15

   

If you’ve been following closely, then you will know that the iPad 3 has been running into quite a few issues that are threatening to delay the release of the refreshed tablet.  We reported earlier that Apple was having difficulties with production times and costs with the A6 Processor as well as the “must have” Retina Display.
The latest rumor coming from DigiTimes who has a somewhat credible history of insider information, references the current problems with retaining the brightness of the proposed super display on the iPad 3.  That display would come in at a resolution of 2048×1536 and be pushing out some truly impressive PPI; but the size of the screen is where Apple and its supply chain have been running into difficulties compared with the smaller display on the iPhone.
Once Apple gets all the bugs worked out including the recent resolved heat dissipation and battery consumption problems, this display is going to be the most sought after and vivid display on the market that some are arguing is the best possible display that can be made.  The human eye can only pick up differences in pixels up to a certain PPI or pixels per inch, meaning that anything over that number would be virtually wasteful as far as production costs and technology go.
The present issues run into by the Cupertino giant and their Taiwanese supply chain is the LED backlight.  The current single LED back-light bar (in the iPad 2) is “insufficient” to maintain and strengthen the brightness of the retina display for the iPad 3.
LED back-light unit vendors or BLUs have proposed two solutions to help Apple.  The first would involve adding a second LED chip inside the single-bar form factor, while the second would be to use a “dual-LED light bar inside the iPad 3, one on the left and one on the right,” to support the display.  Apple is reportedly keener with the second option and will be using that as pre-run production continues.
We’re hoping this is good news that the iPad 3 could still make its debut in March of 2012, but with the past rumor of two tablet models from Apple in 2012, some are still going with the notion that the iPad 3 with these proposed specs won’t be ready in time.  After all Apple only needs to stay slightly ahead of its competitors technology spec plans to remain in the lead
