And now the iPad 3 part photos are really starting to come in thick and fast! No sooner had the rumour appeared that Apple might be considering using Samsungâ€™s IGZO displays for the next iPad, MacRumors prints leaked photos that were posted to a Korean forum that are said to be of an iPad 3 display panel. The picture shows two iPad displays, with the top one being from the iPad 2 and the bottom one said to be from the iPad 3. They are the same size (9.7â€ across), but MacRumors points out that the bottom iPad has a different cabling configuration, and suggests that the three wide ribbon cables attached to the iPad 3 display might be there for additional data bandwidth purposes. If the iPad 3 is to have a high resolution screen of 2560x1600, i.e. four times the pixels of the iPad 2, it will surely need the additional data bandwidth, so that sounds like a plausible explanation.
