Apple has always tried to push the bezel of a smartphone and tablet to the limit, maximising screen potential. A new patent from Cupertino may completely eradicate the bezel and bring it back when the user needs the thumb space.
The patent allows the user to control the bezel space, for small devices or devices looking to maximise screen real estate, this could be a grand move, allowing the user to get the full screen when watching a movie and then some thumb space when writing an email.
Apple does have a slight problem when they apply patents, they sometimes never get round to using them. We may see the bezel-less iWatch or iPad coming soon or Apple may discard this patent like many others.
