Abstract:
1. A method of forming an image, comprising: introducing light into a reflective optical cavity including a plurality of light-transmissive regions through which light can escape the reflective optical cavity; allowing the introduced light to escape the reflective optical cavity through at least one of the light-transmissive regions; providing a plurality of light modulators, each having at least first and second states, wherein, in the first state, a light modulator obstructs a corresponding light-transmissive region thereby preventing light introduced into the reflective optical cavity from illuminating an image pixel that corresponds to the light-transmissive region, and in the second state, the light modulator allows light escaping the reflective optical cavity through the corresponding light-transmissive region to illuminate the image pixel corresponding to the light-transmissive region; and forming an image by selectively controlling the states of the plurality of light modulators.
