A touch panel defect could mean a short iPhone 5 supply come launch day
A touch panel defect on the upcoming iPhone 5 could result in disgruntled, empty handed customers on launch day.
According to Digitimes the panels produced by Wintek suffer from a "delayed bubble" defect that involves bubbles of gas being trapped between the film layers.
The problem is discovered later on during the assembly process.
Digitimes sources note that "Wintek accounts for 20-25% of the total production of touch panels used in iPhone 5, while Taiwan-based TPK Holding accounts for 60-65% and Chimei Innolux for the remainder".
