Abstract

Image display apparatus and methods may use a single imaging element such as a digital mirror device (DMD) to spatially modulate plural color channels. A color channel may include a light steering element such as a phase modulator. Steered light from a light steering element may be combined with or replaced by additional light to better display bright images. These technologies may be provided together or applied individually.
