Apple Patents a Way To Deliver 3D Content Without 3D Glasses

Apple has patented the ability to deliver 3D content to devices like the iPhone, iPad and Macs without requiring 3D glasses. From a report: The company recently filed a patent with the heading of 'Split-screen driving of electronic device displays.' And the tech it describes means that flat screens on smartphones and tablets will be able to show an image in 3D without the viewer having to wear any glasses or VR headset. The idea is that iPhone and iPad screen will be able to display two different images simultaneously, in a way that will fool your brain into seeing a three-dimensional image.
Yes, there are already devices that do this, but the patent notes that existing methods are 'problematic,' stating: 'it can be difficult to provide this type of content on a multi-function device such as a smartphone or a tablet without generating visible artifacts such as motion blur, luminance offsets, or other effects which can be unpleasant or even dizzying to a viewer.' The rest of the patent application goes into a great deal of depth about how Apple plans to resolve these problems, and create a smooth 3D viewing experience on a flat screen without the need for glasses. This is gets hugely technical, but starts from the notion that the screen switches between left and right sides of an image via alternating pixel rows.
The patent is also quite vague about how this will all work on a practical level. It doesn't state, for example, what angle viewers will need to position their iPhone or iPad at to get the effect. But it does show that Apple is serious about developing this tech, and has put some proper thought into it.
