摘要:
A display device is achieved using a simplified optical system which generates an expanded exit pupil without compromising magnification or resolution. Modulated light from a source is converged toward a focal point by an optics subsystem. A scanning subsystem deflects the converging light, and thus the focal point, along a raster pattern to define an intermediate image plane. A lens array defines a surface which coincides with the image plane. The lens array includes a plurality of lenses and a polymer dispersed liquid crystal film. The film serves to spread incident light and thus form an expanded exit pupil.
