According to a CNET report, LG and Samsung are having difficulties in manufacturing high resolution 10-inch displays for Apple’s upcoming iPad 3. This isn’t the first time reports like these have emerged, a couple of months ago DigiTimes also reported issues plaguing Apple’s Retina display manufacturers.
The closest that iPad display manufacturers like LG Display and Samsung can get is 2048×1536 resolution display, according to the source. That’s a PPI of 264, twice the 132 PPI on the iPad 2.
But whether manufacturers can make them in volumes that Apple demands is the question. “They have production plans for 2,048×1,536 displays. Starting in November. But those are only plans at this point,” said the source, referring to LG and Samsung.
“It’s not a question of making just one. That, of course, can be done. The challenge is making lots of them,” the source said. “This is a quantum leap in pixel density. This hasn’t been done before.”
Apple had two options while choosing Retina Display for the iPad. The first was to reach a pixel density of 326 PPI, the screen density of the iPhone 4 and iPhone 4S. The other was to achieve a resolution double that of the iPad 2, making the density 264 PPI.
According to CNET, Apple went with the second option because iPads aren’t held as close to the eye as iPhones and a pixel density of 326 PPI would make the screen so dense that it would be hard for the human eye to notice the level of detail.
Apple also has a fallback option in case LG and Samsung can’t manufacture enough of these high resolution displays – a relatively less dense screen resolution of 1,600×1,200. This however seems unlikely since it isn’t a whole number multiple of the current generation iPad resolution – 1024×768 – which would make it difficult for developers as well as Apple to manage backward compatibility.
Difficulties in keeping up with huge demand is a problem that Apple and its suppliers had to deal in the past with the original iPad as well as the iPad 2. It was just in July of this year, that Apple was able to cope up with the demand for iPad 2 and with 5 months still to go for the iPad 3 launch, Apple’s manufacturers have enough time to get things sorted as iPad 3 without Retina Display would be disappointing.
