It's long been asserted that the next iPhone would be the first to feature a larger screen - most likely a 4-incher. However, it seems the true innovation here will be in the display's thickness. According to the Wall Street Journal, "people familiar with the matter" have revealed that the next generation iPhone will use in-cell touch technology.
Modern smartphone displays are made up of several layers - one for the LCD components, one for the touch sensors and one for the glass that we, the users, actually interact with. In-cell technology effectively removes one of these stages by squashing the LCD and the touch components together into a single layer.
The benefits of this approach are two-fold. For one thing the removal of a layer makes in-cell displays a fair bit thinner and lighter than current mobile screen standards, which would certainly help Apple minimise the impact of adding an extra half-inch of surface area to its beloved smartphone.
The second benefit is clarity - one less layer means that the picture is even clearer and brighter. Considering the iPhone 4 and iPhone 4S contain some of the finest displays to be found on any smartphone as it is, this is exciting news.
According to the report, Japanese manufacturers Sharp and Japan Display are already manufacturing these new in-cell displays, which would add further credence to the suggestion that we'll be seeing the iPhone 5 some time in September or October.
