Patent ID: 6999071

Claim:
An apparatus for displaying 3D images, the apparatus comprising a, a screen for direction selectively transmitting and/or reflecting light, b, a screen illuminating system, the screen illuminating system comprising c, modules for generating light beams, the light beams being associated to multiple different points of the screen, and being associated to different emitting directions of the points of the screen, and further d, the screen providing divergence to the transmitted or reflected light, according to the angle between neighbouring emitting directions, and the apparatus further comprising e, a control system for controlling the modules, characterised in that f, the modules further comprise a two-dimensional display, and g, an optical system for simultaneously imaging the individual pixels of the display onto the screen, where h, the display pixels on the two-dimensional display associated to the different points on the screen and corresponding to the different emitting directions associated to the different screen points generate substantially simultaneously light beams with different co-ordinates but substantially without emitting direction information, and i, the imaging optics associated to the display substantially simultaneously images the light beams generated by the display pixels with different co-ordinates into different emitting directions or imaging directions.
