Reports have emerged that Apple is tapping Japanese firm Sharp to supply the screen display that the tech giant will install on the rumoured iPhone 6, this time able to recognise handwriting using an ordinary pen.

Sharp will reportedly bring in a new display technology to the upcoming Apple handset that will enjoy "up to 8 times higher sensitivity to a capacitive touch panel," per reports by PatentlyApple.

With Sharp coming to the Apple supply chain, it is likely too that the projected screen size of the iPhone 6 will be stretched to five inches at the maximum, also the optimal screen setting offered by the fully-developed Sharp technology.

The new screen display allows too the production of thinner display component for the iPhone 6 while at the same time accommodating the possibility of direct handwriting on the gadget screen.

That should mean users can write notes and compose an email or text message without relying on a stylus, which Apple co-founder Steve jobs had dismissed an unnecessary tech tool.

"It'll be the first time in history that a user will be able to write on a display using an ordinary pen or pencil for taking notes," PatentlyApple said.

Another added premium is the ability to scale the iPhone 6's 5-inch screen to TV monitors with up to 60-inch screen size without compromising the Full HD rendition.

However, the same report noted that there is no assurance that Apple will deploy Sharp's display technology with the iPhone 6m, which analyst said will most likely come out on Q1 2014.

While Apple has yet to comment on the likelihood that it will enter the phablet arena, analysts believe the bigger iPhone represents one of the killer offerings that the tech giant will unveil in the quarters ahead to check the rising surge of its chief rival, Samsung.

Apart from the large-screen iPhone 6, Apple is also rumoured to release a budget iPhone version, alongside the iPhone 5S by June or July this year, the expanded models apparently to compete with the wide-range of choices offered by Samsung's Galaxy smartphone lines.
