Method and apparatus for miniaturizing digital light processing displays using high refractive index crystals

摘要

A digital light processing display system is provided with fewer major moving parts and a smaller form factor. A high-intensity, high-frequency strobe light is used to direct a pulse of light through colored filters. The colored pulses of light are passed through separate prisms, each with a high index of refraction. The index of refraction and the length of the path through the prism result in a delay for each color. For each pixel with a component of the color for each colored pulse, a controller activates the corresponding mirror in an array of mirrors. The timing of the activation of the mirrors is coordinated with the timing of the colored pulses of light to form a full color image.
