PROJECTION DISPLAY DEVICE AND METHOD OF DISPLAYING FULL IMAGE FOR PROJECTION SURFACES OF ARBITRARY SHAPE OR INCLINED PROJECTION SURFACES Russian patent published in 2016 - IPC G03B21/14 H04N9/31 

FIELD: optics.

SUBSTANCE: versions of invention relates to image projection display device and method for mapping of full image. Projection display device includes image forming system, which is implemented so that set of points in sub-images, each of which is applied in corresponding common point in common image due to multichannel optics, differs depending on what distance corresponding to common point in full image to multichannel optics.

EFFECT: higher quality of projecting at desired level of miniaturisation using surfaces projection of arbitrary shape or inclined surfaces projection.
