Sharp has just announced that they will produce a 5.5-inch screen with a "mind-boggling" 806 pixel density. The company is set to mass produce 4K IGZO displays in 2016. It was said that Apple might release a phablet sporting this display, which could contend the company's rivals such as Samsung.
Recent reports mentioned that Sharp would produce a 5.5-inch screen that has a 3840 x 2160 resolution, which could fit in phablet devices. At some point in the near future, Sharp is going to release 4K IGZO displays that would contend Samsung's 4K AMOLED screens, which some are expecting to see the display featured in the Galaxy Note 5.
There are speculations that Apple could release a phablet, either iPhone 6S Plus or iPhone 7 Plus, sporting a 4K IGZO supplied by Sharp, since the two are long-time partners. It is reportedly "wise for Apple to supersize further with its upcoming phablet" as Samsung's Galaxy Note 5 is expected to have a "near desktop-class" display, and LG's G4 with Quad HD screen technology.
The only downside of having an 806 ppi resolution is that its power consumption is moderately higher than QHD displays. However, Apple has been offering battery-related job hires recently. At least nine listings were reportedly connected to battery technology, which included a battery life software engineer, a power analytics engineer, and a software power systems engineer. Taking note of these three listings, Apple is said to seek a candidate who is "able to think of innovative solutions to improve battery life, while always delivering great end user experience."
So far, Apple has not yet given any statement about their device releases. Speculations are saying that the company might release an iPhone 6S or an iPhone 7.
IGZO means indium gallium zinc oxide. This semiconducting material is used in the backplane of flat-panel displays (FPDs) in devices such as smartphones, tablets, 32-inch LCDs, and others. Because of its high electron mobility, IGZO can improve the speed, resolution, and size of various flat-panel displays. That is why the material is taken as one of the most promising thin-film transistors for use in OLED displays.
An example of using IGZO in OLED displays is LG's 55-inch OLED TV. Further, IGZO can be employed in LCD panels. One example is Fujitsu's 14-inch 3200x1800 LCD ultrabook PC.
