A display system is disclosed for use in an augmented reality display (30), the system comprises a waveguide (32) having a front surface and a rear surface. A front input projector (34) projects polychromatic light through a front surface, and a back input projector (36) projects polychro matic light through the rear surface. Input light impinges on an input grating (38) on a rear surface of the waveguide (32), and light travels through the waveguide by total internal reflection. An output grating (40) is provided for coupling light out of the waveguide. A plurality of front and back input projectors (34, 36) are provided in a staggered configuration along the width of the waveguide (32) and respective edges of adjacent front and back input projectors are aligned along the width of the waveguide to permit a continuous projection of light.
A display system for use in an augmented reality display, the system comprising:
The display system of any of the preceding claims wherein the respective fields of view of the first and second input projectors are arranged so that there is substantially no gap between them, along the width of the waveguide.
The display system of any of the preceding claims wherein the first and second faces are substantially parallel in the waveguide.
The display system of any of the preceding claims wherein the first and second input projectors are arranged on opposite sides of the waveguide.
The display system of any of the preceding claims comprising a plurality of first input projectors and a plurality of second input projectors arranged on successively opposite sides of the waveguide across its width.
The display system of any of the preceding claims wherein the normal of the at least one input grating is tilted with respect to the light projected by the first and second input projectors.
The display system of any of the preceding claims comprising a first input grating configured to couple light from the first input projector into the waveguide and a second input grating configured to couple light from the second input projector into the waveguide.
