Patent number: 10726609Abstract: A multi-layer display may include a first screen and a second screen arranged in a substantially parallel manner, with the first screen and the second screen including an array of pixels and the second screen overlapping the first screen, a light configured to provide light to the first screen and the second screen of the multi-layer display system, and a processing system comprising at least one processor and memory. The processing system may be configured to apply perspective distortion to automatically bake the desired aspects of perspective into a physically thin object. To achieve this, the object's vertices are moved along lines drawn through a fixed point in space (a primary viewpoint). From this viewpoint, regardless of any perspective distortion applied, the object will appear to not change.Type: GrantFiled: November 21, 2018Date of Patent: July 28, 2020Assignee: Pure Depth LimitedInventor: Austin F.
