Google took another step toward a commercial version of its Google Glass eyewear by acquiring a small stake in a unit of Taiwanese chipmaker Himax Technologies Inc that develops tiny displays. Himax’s shares were up a third to US$6.86 on the Nasdaq. Google will take a 6.3 per cent stake in Himax Display (HDI) and has an option to raise its stake to 14.8 per cent within a year, Himax said in a statement without disclosing the financial details. Google confirmed the deal in an email to Reuters and said Himax Display had been its partner for several years. Himax said the investment would help fund production of liquid crystal on silicon (LCoS) chips and modules, tiny devices used to project images inside head-mounted devices such as Google Glass as well as head-up displays and pico-projectors. As competition moves from smartphones and tablets to wearable technology, Google is pushing its eyewear as rivals Apple and Samsung Electronics work on devices to be worn like a wristwatch. Described by Google chief executive Larry Page as vital to the company’s future, Google Glass incorporates a stamp-sized display mounted on the left side of a pair of eyeglass frames that can record video, access messages and retrieve information from the Web.

Developers, such as those at eBay, have already started working on potential apps, while venture capital firms have teamed up to provide funding for startups working with Google Glass. Google, which has unveiled its own apps for Glass, has distributed the device to a limited set of early users and developers, and expects to make it available “more widely” later this year. Jay Srivatsa, managing director of equity research at Chardan Capital Markets, said the investment by Google endorsed Himax’s capabilities in LCoS displays and confirmed the Taiwanese company as a “key supplier” to Google Glass. Srivatsa, rated three out of five by StarMine for the accuracy of his Himax earnings forecasts, estimated Google’s investment in the unit to be in the range of US$20 million to US$40 million.
