Rumors are swirling around the net about what Apple is going to do about the new display for its iPhone 5. We know that it is going to be an IGZO (Indium, Gallium, Zinc , Oxygen) display. We also know that it will be 4 inches. What I do not know for sure is the manufacturer of the display. Some speculate Sony and Hitachi others say Sharp. From what I have been following it looks like it will be Sharp. Whoever makes the display the faithful are bound to be thrilled. These panels are also bound to be used in the next Apple iPad

According to Shuji Sako of Sharp, ¨The IGZO LCD panel´s performance outclasses anything attainable with conventional amorphous-silicon TFT panels.¨ IGZO transistors have mobility of its electrons up to 40 times higher than amorphous-silicon thin-film transistors. The IGZO transistors can also be made smaller and have the same performance. This helps the display save 30% in energy consumption and higher resolution over the traditional amorphous-silicon TFT panels. The display is said to perform at 330 dpi. The IGZO display would also enable the iPhone 5 to be thinner.

The demand for small and mid-size LCD panels is growing rapidly putting strains on the supply chain. What many tech blogs fail to say is that this amazing growth also puts strains on the natural resource supply chains. The technology needs Indium, Gallium and Zinc. Two of these metals have been deemed to be at Critical Levels according to the British Geological Survey and the US Geological Survey. Over 95% of these rare industrial or technical metals are supplied by China. Even if the prices of the metals go up 100% the end user will see a very small price increase because such a small amount of the metals are used in each device.
