Apple has been widely rumored to be readying a Siri-enabled television for release this year, but a new report claims component availability issues will prevent the highly anticipated “iTV” from launching in the first half. Citing unnamed sources within Apple’s supply chain, DigiTimes on Friday reports that Sharp, rumored to have been contracted to supply display panels for Apple’s debut HDTV, is not yet ready to ship the indium gallium zinc oxide (IGZO) panels Apple will use in its iTV. According to the site’s sources, upcoming HDTV models from Samsung and LG will occupy much of the OLED panel capacity during the first half, so Apple has chosen to instead utilize IGZO panels. Sharp is reportedly not yet ready to mass produce its latest IGZO panels, however, and Apple’s iTV launch may have been pushed to the second half as a result. Apple’s iOS-powered iTV will reportedly support apps and feature voice controls powered by Siri as well as access to on-demand content through iTunes.
