The IPS (in-plane switching) displays used in the current iPhone 4S and iPad 2 could make way for a different type of panel in Apple’s upcoming mobile devices. Citing “sources in Apple’s supply chain,” Digitimes is reporting that Apple will use IGZO (indium gallium zinc oxide) panels possibly starting with the next-generation iPad.
The IGZO panels are to be provided by Sharp. In preparation for what could be a substantial order, it has reportedly begun switching some of its production capacity for large-size panels to smaller-sized panels suitable for smartphones and tablets.
IGZO panels could allow Apple to offer displays with a resolution of up to 330 dots-per-inch. Given the rumours that the next iPad will feature a higher resolution display, it’s not unlikely that Apple is at least considering this technology. Add to that the fact that IGZO panels would not require dual-bar LED backlighting and offer better power management and the argument gets even more compelling. The catch: IGZO panels apparently have lower yield rates than IPS ones. Perhaps Sharp has solved this.
