Consumers waiting for the new iPad Mini may have to wait awhile longer. Apple is pushing back the launch of the Mini 2 due to burn-in problems on the tablet’s LCD panel, claims Korean News site ETNews. Citing an unnamed industry source, ETNews says that the glitch stems from the IGZO (indium gallium zinc oxide) technology used for the panels manufactured by Sharp. The smaller pixels required for the Mini 2’s Retina display pose a challenge to the technology, thus creating production issues. Though the burn-in is not visible to the naked eye, the panels don’t meet the technical standards to pass Apple’s muster. LG Display also is making panels for the Mini 2. However, it uses a different method. As a result of Sharp’s issues, Apple is currently talking to archrival Samsung about supplying display panels for the Mini 2 starting next year, according to the sources.
