Strong demand for Apple’s iPad 2 tablet has reportedly lead the Cupertino-based company to add a third touch panel manufacturer to its supply chain. Bloomberg has confirmed the deal with two anonymous sources who claim that Foxconn affiliate Chimei Innolux will begin supplying touchscreen displays for Apple’s iPad 2 beginning next month. The Taiwan-based manufacturer will join Apple’s current iPad 2 touch panel suppliers, Wintek and TPK Holding, which apparently have not been able to combine to meet the unrelenting demand for Apple’s latest tablet. Apple declined to comment on the deal, as did Wintek, TPK Holding and Chimei Innolux.
