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 polychromatic 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. |
