Here’s how Apple’s new retina display on the new iPad works
No doubt Apple’s display gives a resolution four times that of any tablet out there, not just the iPad 2. Apple uses a Super-high aperture or SHA display. They apply a 3 µm (smaller than mm) layer of resin under the display. This layer then creates a gap between the pixel electrodes receiving the signal. This is the magic elixir that lets Apple squeeze in more pixels than the others. That is it!
