Apple to Use IGZO Displays to Achieve a Thinner Lower-Power iPad 3?
The latest Digitimes report claims 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.
Given Digitimes' misstep just yesterday about Apple's plans for Macworld, it might be hard to take their new report at face value.
However, this is not the first time that we've heard that Apple will be pursuing this new technology for the iPad 3. 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.
Sharp announced plans in April to commercialize these new IGZO panels for mass production later this year. The advantages of the new technology that should allow for lower power consumption and higher resolution displays. 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) based high resolution LCDs like the rumored 9.7-inch 2048×1536 IPS LCD for the iPad 3.
It sounds as if this new technology will allow Apple to avoid adding a second light bar system to the more traditional IPS display that is presently used in the iPad. It may also allow Apple to avoid making the iPad 3 thicker than the current iPad, and should consume less power.
