Before the new iPad was announced, there were only couple of android tablets that could do 1920×1080 at 10″ screen. That was among the world’s densest display in consumer grade electronics but the iPad changed it all.
iPad 3’s aka iPad sports super high 2048×1536 resolution on a 9.7″ screen, 264ppi. This changes everything.
The display is made possible with technology called Super High Aperture.
However, it wasn’t developed or manufactured by Apple. The credit for the Magic goes to Sharp and JSR (a display materials maker from Japan).
Super High Aperture 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 drain that it used to be in iPad 2.
However, as super high resolution displays for mobile applications have increased the importance of high transmission and low power consumption, SHA has now become a critical technology for manufacturing high quality LCDs. Already more than 25% of LCDs adopt SHA technology and that is likely to continue to grow in the future.
The method used reduces unwanted capacitive coupling and enables the electrode to be extended over the gate and data lines without causing cross talk or affecting image quality—thus increasing aperture area.
