Some of the folks who lined up and picked up a shiny new iPad 2 today are reporting that the device’s screen exhibits a faint yellow tint. Remember that iPhone 4 owners also experienced a similar phenomenon and that the yellow shade eventually dissipated.
Explaining the issue as it pertains to the iPhone 4 and invariably the iPad 2, an AppleInsider forum poster had this to say this past Summer:
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.
How do I know? I was involved in pitching Z-6011 to Apple.
So there ya have it.
