Today the iPhone 4 was launched in many countries however a few big problems have arisen. The first one being the retina display which on 1000’s of users iPhone 4 is showing a yellow tint in parts of the screen.
However there has been a follow up on this issue someone posting on the AppleInsider forums seems to know why:
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.
