The iPhone 4 launch fiasco is about to repeat itself. A defect has presented in some iPhone 5 touch panels produced by Wintek which may affect the ability to meet initial shipment targets for the launch which is expected in October, according to iPhone supply chain makers.
In response, Wintek simply indicated that all of its products are being delivered on schedule.
Wintek, is the company where n-hexane poisoning took place this time last year. N-hexane, a poisonous chemical was used to quicker manufacture iPhone4 screens. Wintek still accounts for 20-25% (while Taiwan TPK Holding accounts for the rest) as Apple has no problem in putting their worker's health behind profits.
"The defect, "delayed bubble", is difficult to avoid during panel production, particularly when the defect is not detected during the process of laminating touch panels, and only later found during assembly, the sources said."
More advanced smartphones use AMOLED or SuperAMOLED screens that are thinner, use less power and to not require the old "lamination" procedure as the display and the touch screen are one and the same panel.
