CA 2133977

2133977 9321673 PCTABS00027 A visual display system is disclosed which utilizes one- and/or two-dimensional arrays of visible emitting vertical-cavity surface-emitting lasers (VCSELs) (200) in order to provide a desired visual display within an observer's field of view (220). Sweep and subscanning techniques are employed, individually or in combination, to create a full M x N image from 1 x L or K x L arrays of VCSELs, where M and N are multiple integers of K and L, respectively. Preferably, the VCSELs (200) are contained within a display housing which may be attached to the head of the user by an attachment mechanism or may alternatively be hand held or mounted to a surface. The circular symmetry and low divergence of the emitted VCSEL radiation as well as the availability of multiple wavelengths, particularly, red, blue, and green, allow high resolution monochrome or color images to be generated.
