Sharp starts producing IGZO panels for smartphones and tablets
designers looking to increase the resolution on a product's screen, and those looking to build a slim device. The material used in producing these screens allows for the use of smaller TFTs and more illumination for each pixel which reduces the need for a powerful backlight. Had the IGZO panels been available in time to use on the new iPad, the third iteration of Apple's tablet might not have needed the bigger battery and thicker footprint necessary to include extra LED backlighting. The latter is required to keep the unit's 2048x1536 resolution Retina display bright. The IGZO panels were unable to be used for the most recent iPad model because the panels failed Apple's approval process.
