Apple again rumored to switch to IGZO displays for 'iPad 3'


Digitimes has reported that Apple will be utilizing IGZO (indium gallium zinc oxide) flat panels instead of IPS (in-plane switching panels) in its "next-generation mobile display products" such as the iPad 3.

Starting with the new iPads, Apple will utilize IGZO panels from Sharp in order to upgrade the display resolution of the new tablets to full HD level, the sources indicated.

Though, such rumors aren’t new ones. We have already heard that Apple could use this technology in the next-generation iPad. A research note from Jefferies analyst Peter Misek back in November made very similar claims:

Also, we believe that Apple and Sharp together have a modified IGZO (indium, gallium, zinc) technology to achieve 330 dpi, which is sufficient for an HD display while not using IPS nor having to include dual-bar LED backlighting. In our view, this should lead to several design advantages, namely the device can be thinner, battery life should be longer, and the overall experience for users should be meaningfully improved.

In April, Sharp revealed its plans to commercialize new IGZO panels for mass production later this year. DisplayBlog recaps the advantages of this new technology:

The benefits of IGZO are plenty: lower cost of manufacturing, up to 30x higher electron mobility than a-Si (amorphous silicon), increased aperture ratio for improved light transmittance, higher resolution in terms of ppi, etc. IGZO would allow for significant cost reductions compared to LTPS (Low Temperature Poly-Silicon).

The new technology is said to allow Apple not to use a second light bar system that is presently used in the iPad and to avoid making the iPad 3 thicker than the current iPad.
