Preview at WWDC likely in June, followed by September launch.
iPad 2 Yellow Screen Tinting Likely to Go Away Like iPhone 4?
iPhone 4 discoloration
A few readers have noticed a yellow tinting on their brand new iPad 2 screens. The color changes are reminiscent of a similar issue that appeared on early iPhone 4 shipments. At the time the issue was described as follows:
Apple is using a bonding agent called Organofunctional Silane Z-6011 to bond the layers of glass. Apparently, Apple (or more likely Foxconn) is shipping these products so quickly that the evaporation process is not complete. However, after one or two days of use, especially with the screen on, will complete the evaporation process and the yellow "blotches" will disappear.The issue seemed to resolve itself over a couple of days for the iPhone 4 based on reader experiences. With any brand new launch, Apple seems to be shipping the units as quickly as they are manufacturing them, preventing the required time for the bonding agent to set. We'll know for sure in a few days.
