The next generation of iPad, the iPad 3, will have improved LED backlight solutions so the device’s screen may have a better screen resolution. According to Digitimes, the new resolution is likely to be higher than 2048X1536 pixels.
Currently, iPad2’s screen provides 1024×768 resolution.
The Retina display includes LED backlighting and an ambient light sensor that automatically adjusts the brightness of the screen for the best viewing and battery life possible.
It also means the LED light bar in the current iPad2 needs to be improved otherwise the brightness levels required in the retina display would not be sustainable.
Some Taiwan based manufacturers have suggested that the light bar be kept in single bar form factor. There would be two LED chips inside though Apple is likely to go in favour of dual light bars. The problem surrounding mass production of retina display, as suggested by earlier reports, seems to have cleared up by now as well.
When the Retina Display arrived in iPhone 4, it was billed as a great way of viewing photos for the users but the similar pixel density for iPad 3 would likely turn out extremely useful for professionals, such as pilots who would be watching their electronic charts on the tablet and the doctors would watch the medical imaging on iPad 3.
In fact, many airlines have already started replacing their flight bags with the iPad, though the pilots still cannot use iPads for in route charts because of the complexity involved in them. Even in medical imaging, doctors are already using iPads to view the images. The larger screen devices arrived on Android first but Apple was the first to bring high resolution, Retina Display, on its screens. The iOS already has the necessary ground work done to support Retina Dislay for iPad, so users may not expect any problems on that part.
