Two of Apple's touch panel suppliers, TPK and Wintek, wiil see shipments to drop by 15 to 20 percent in the current quarter because of the transition from the iPhone 4S to the next-generation iPhone, industry sources tell DigiTimes. The 4S is described as "moving into the final stage of its product life cycle," and TPK has previously stated that it expects revenues to fall 10 percent sequentially in Q2 as a result of iPhone 4S stockpiling and people holding off on buying an iPhone.
