There's been speculation for a while that Apple will replace the iPad's glass-on-glass (GG) structure with one or another alternative, partly to make it thinner, partly to improve manufacturing yields for this components. NPD DisplaySearch's Calvin Hsieh noted in a January assessment -- "Is Apple Changing its Mind on Touch Panel Structures?" -- the widespread belief that both in-cell and glass film dual ITO (sometimes rendered as GF2, according to one analyst) have relatively lower yields and therefore higher costs for now (though Apple evidently thinks those drawbacks are outweighed by consumer preference for thinner and lighter tablets).
Hsieh actually doesn't answer the question he poses. Rather he lays out the complex issues -- including adequate manufacturing volumes and intellectual property sharing -- that Apple faces in switching to two alternatives. One is a proprietary touch-on-display technology from Innolux, "a type of on-cell touch structure in which the sensor is located on the upper glass (the color filter substrate), beneath the top polarizer." The other is one-glass-solution (OGS) technology, which integrates the touch ITO sensor circuits into the cover glass. Taiwan's giant LCD maker, TPK, holds extensive patents in this area, according to Hsieh.
Hsieh references Asian news reports that both Innolux and TPK recently have delivered samples of their respective products to Apple. But that timeline, if true, might make it difficult for Apple to introduce either technology in a 2013 iPad 5.
iPad 5 suffering from low yields of stereo speaker rumors
"One of the things that has bugged me about Apple's flagship tablet since the first iPad arrived in 2010 has been the device's lack of stereo speakers" grouses Bryan M. Wolfe, in a post at AppAdvice, headlined "The One iPad 5 Rumor We Haven't Heard Much About But Really Should."
So actually there are two things bugging him. The second is there aren't enough rumors about stereo speakers for the Next iPad. Apparently, Wolfe would feel better about the future of iPad stereo if there were more rumors about them. Welcome to surreality.
"While this was okay many iPad versions ago, it has become increasingly unacceptable," he declares, sounding increasingly vehement. "This is especially true given what the competition has done with tablet speakers, as has Apple with the iPad mini."
Like what, you ask? "The $199 Kindle Fire HD includes dual-driver stereo speakers that include Dolby Digital Plus technology. And yes, users can experience this with or without a headset."
