Luckily, the display experts over at DisplaySearch can explain what exactly Apple did to pack four times the amount of pixels onto the new iPad screen compared to its predecessor’s (none-too-shabby) display. According to DisplaySearch, Apple did it using a pixel-design technique called Super High Aperture, or SHA, which has a highly technical explanation:

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. As we explained in our TFT LCD Process Roadmap Report, this 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.

If that wasn’t completely clear to you — and you’re not alone — here’s a graphic DisplaySearch put together showing what this design looks like in cross section: …
