Apple made sure to remind us of how difficult it was to squeeze in four times as many pixels into its new iPad Retina Display, and that it was a ‘breakthrough’. But how about a technical explanation of how it was accomplished? DisplaySearchBlog gives us the fine details:
If you didn’t catch what Apple means by that, they are referring to SHA (Super High Aperture) pixel designs. SHA is a method of increasing aperture ratio by applying approximately a 3 µm thick photo-definable acrylic resin layer to planarize the device and increase the vertical gap between the ITO 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.
That makes total sense, right? SHA technology was noted to have been started by Sharp and JSR years back. You’ll be getting your hands on the Retina Display, hopefully by Friday.
