Super High Aperture: it's why the new iPad's Retina display is so dense

Super High Aperture. Heard of it? Probably not, but thanks to Apple, you'll probably long for days when you didn't in just a few months. According to an in-depth look from the folks at DisplaySearch, the aforesaid technique is the primary reason that Apple was able to shove 2,048 x 1,536 pixels into the 9.7-inch panel on the new iPad. Not surprisingly, it wasn't Apple that conjured up the magic; instead, it was crafted by engineers at Sharp and JSR (a display materials maker from Japan), but it'll be the iPad that makes an otherwise geeky achievement something that the mainstream covets. According to the science behind it, SHA is "a method of increasing aperture ratio by applying approximately a 3 [micrometer] thick photo-definable acrylic resin layer to planarize the device and increase the vertical gap between the [indium tin oxide] pixel electrodes and signal lines." Reportedly, there are also "at least twice as many" LEDs in the panel compared to that on the iPad 2, further suggesting that there's way more battery within the new guy than the last. Technophiles need only dig into the links below to find plenty more where this came from.
