Display apparatus and method of displaying using light source and beam scanning arrangement

Abstract

A display apparatus includes at least one light source per eye, the at least one light source being operable to emit a light beam; at least one beam scanning arrangement per eye, the at least one beam scanning arrangement being configured to direct the light beam towards a projection surface, and to sweep the light beam according to a scanning pattern, the scanning pattern being substantially in a form of a spiral; and a processor configured to control the at least one light source and the at least one beam scanning arrangement to draw at least a first region of an input image over the projection surface, wherein a resolution of the first region of the input image is to vary as a function of an angular distance from a centre of the spiral.
