The mythical Apple tablet was supposed to be launched before the now expected Q1 of 2010, but a problem with the touchscreen forced the Cupertino based firm to delay the release of the product. Not only was the tablet delayed because of problems with the strength of the glass panels used for the display, the problem has forced Apple to seek other vendors who can offer a solution to the problem. According to DigiTimes, Innolux, a subsidiary of the Foxconn Group that will manufacture the tablet and puts together the iPhone, will be the primary source of the 10 inch touch panels for the tablet with Wintek becoming a possible secondary supplier at a later time. Foxconn's glass processing subsidiary, G-Tech Optoelectronics, will provide a process for strengthening the glass along with Taiwan based Wah Hong Industrial. The latter is a company that makes optical film. The Apple tablet is expected to be introduced in late January with shipments to take place starting in March or April based on DigiTimes analysis of the shipping schedules of Apple's component partners.
