Apple has switched suppliers for the iPad's capacitive touch panel to keep production running, a rumor from Taiwan argued on Friday. The company has supposedly been relying on TPK Touch Solutions for some of the panels but, frustrated with delays, has moved more orders to Wintek to keep production moving. A previous rumor had blamed Wintek itself, but it's implied by DigiTimes that Wintek has either addressed earlier problems or would be used to balance the workload.
