<p>A colour display device including a chromatic dispersive grating and an active matrix such as a liquid crystal active matrix. The device further includes a spherical microlens matrix in which the cross-sectional shape of the microlenses is such that the RGB-coloured beam spread may be compensated by the use of a dispersive grating, and thus the use of the circular aperture of the projection lenses may be optimised.</p> |
