iPad 3 Codenamed “J2″, To Carry 2048 x 1536 Resolution Display? – [RUMOR]

Following a number of reports to surface from Taiwanese publication DigiTimes over the last few weeks, 9to5Mac claims that it has found what it believes is the codename for Apple’s upcoming “iPad 3″. Found deep within iOS 5‘s source code, the string “J2″ has been uncovered which surprisingly matches up perfectly with the codename discussed by DigiTimes in one of its previous reports.

The report reads:

Apple is currently giving two tablet PC projects codenamed J1 and J2 to its upstream partners for development. The sources revealed that the major differences of the new tablet PCs compared to the previous model are their size, specifications and technologies.

Codenames aside for a second, the report also notes that Apple could be looking into alternative ways to backlight the iPad 3′s rumored “2048 by 1536″ display, highlighting that Apple intends to use two LED light bars versus just one to achieve this.

Since the new tablet PCs have a higher resolution, Apple has demanded the design of the light source to be changed from a single LED light bar to two LED light bars on the left and right sides of the machine, but since the method of adopting two LED light bars has created difficulty in shrinking the machine’s thickness, some vendors have come out with designs that only adopt one light bar, but are packing two LED chips into one package.

Although, this isn’t the first time we’ve hear that one of Apple’s future iPad iterations may feature a 2048 x 1536 resolution display. In January of this year, Engadget reported that an update to iBooks contained “Retina”-ready artwork fit for viewing on a 2048 x 1536 display. At the time it was thought this display would be present on Apple’s iPad 2.

Then, in March, a number of strings were found in the iOS 5 SDK suggesting Apple’s next-generation iPad could carry a Retina display.

From the original report:

Kuo now claims that iPad 3 will deliver a Retina Display-like quality and resolution doubling to 2048×1536, an enhancement originally thought to make it into the more immediate release of iPad 2.

This was then followed by reports in July suggesting Apple has already began testing a new display for the iPad 3, dubbed a ‘“HD”-Quality Display’, which would be manufactured by LG. This was never confirmed to be the case.

Finally, in August of this year, The Wall Street Journal stuck its neck out and claimed the iPad 3 would be announced in “early 2012″, also noting that it believed the device would likely carry a “high resolution display”.

According to DigiTimes this week, Apple’s Retina display-boasting “iPad 3″ is expected to arrive in the third quarter of 2012, with the introduction of a possible stop-gap model (codename J1) in Q1 or Q2 next year.
