Most rumours suggest
that the screen will have a Full HD 1,920x1,080 resolution. However, we think
that the resolution could be wrong, mostly because of the way that Apple works.
Generally speaking
Apple likes resolutions that scale easily from previous products, so it and
developers know how apps will look on-screen. Full HD doesn't do this from the
existing iPhone or iPads. We think that Apple could quadruple the existing
iPhone 5S's screen resolution, giving an iPhone 6 with a resolution of
2,272x1,280 instead. We've covered why
the iPhone 6 won't have a Full HD screenin more detail.
Increasing the screen
size isn't all that Apple seems to have planned, as the company is also looking
at ways of improving image quality. Apple has long been known for its
high-quality screens and it seems that it wants to stay ahead of the pack with
its latest smartphone. This time around, Apple is said to looking atquantum
dot technology for the iPhone 6.
Quantum dots are
man-made nanoparticles of semiconductor material, used to create light. They're
so small that quantum effects start to take place. Without getting too bogged
down in the science, the result is that the size of the dot affects its
behaviour.
From a display
manufacturer's point of view, this behaviour can be harnessed, as the size of
the quantum dot directly affects the wavelength of its light emission. The
smaller the dot is, the closer to the blue end of the spectrum; the larger the
dot, the closer to the red end of the spectrum it gets.
What's exciting about
this is that displays can be fine-tuned using quantum dots of specific sizes.
It means that a display can show more accurate colours. Quantum dot is not new
technology and the Kindle
Fire HDX uses this
technology in its screen already. However, as we noted in our Kindle review,
one of the downsides was some light bleed around the edge of the screen.
Apple is aware of this
problem and is working to correct it. According to recent patents, discovered
by Patently Apple, the company is also working on a methods to
improve colour gamut. If Apple can overcome some of the limitations of quantum
dot technology, the iPhone 6's screen could be hugely impressive
