Sources at upstream component suppliers told DigiTimes that Apple's next-generation iPhone will get a 4" screen to compete with the Google Android platform in the 4" to 7" smartphone/tablet market:
The component suppliers noted that the production lines for Apple's next generation iPhone have begun testing, and Apple is interesting in expanding the screen size to 4-inches to support the tablet PC market as the vendor only has a 9.7-inch iPad in the market.
In fact, smartphones that adopt the Google Android platform are mainly 4-inch and larger models. Samsung Electronics' Galaxy S and Google's Nexus S adopt 4-inch panels, Sharp adopts 5.5-inch for its smartphone, and Acer plans to launch a 4.8-inch smartphone. With Apple joining the 4-inch and larger market, 4- to 5.5-inch will become the major battlefield for smartphones and further change the industry dynamics for small- to medium-size panels.
