Samsung Electronics has been developing 12.2-inch tablets and adopted a film-based capacitive touch solution mainly provided by China-based Shenzhen O-film Tech, with production to kick off at the end of 2013, according to Taiwan-based supply chain makers.

　　With its advantage of in-house memory, panels and assembly as well as global brand reputation and marketing resources, Samsung's initiative to offer large-size tablets may cause other vendors to follow suit in 2014, the sources said.
