A new concept for displaying images to a viewer has been patented. It uses new principles for creating an image on the viewer's retina. An image with a particular resolution can be considered as a distribution of picture elements in two dimensions within the integration time of the human eye. The image production can now be divided between two separated display elements which can combine the generation of pixel information in a number of different ways. Synchronization between the display elements is essential. The first and second display elements are arranged at a distance from one another along a line creating a viewing direction for the viewer, which essentially coincides with the direction from the viewer to the first display element. The second display element is carried by the viewer and as he moves, the image remains in a fixed position in space, different to a conventional head-mounted display. Other features possible are: physically small displays; large image angles and/or high resolution; 'private' image seen only by those using personal equipment; separate images to different viewers (e.g. blank display); stereo and 'real' 3D. Demonstrators have been built using TV sets, LED arrays and laser scanners as the first display element, and low-frequency optomechanical deflectors or FLC switches as the second display element.
