In respect to suggestions from customers the upcoming device should feature a USB port, front and rear facing cameras and also should have Retina Display which is speculated to be unveiled in the first half of 2011.
According to recent news this next generation iPad’s Back Light Units will be extensively supplied from Coretronic which clearly indicates that there will be no AMOLED displays because this particular display doesn’t require any back lighting.
It has also been brought into consideration that for LCD displays of the next generation iPad, Chimei Innolux and LG are in contention. So it is completely sure that the next version of iPad will have LCD panel.
