Key Technology
A combination of two laminated prisms, a TIR prism effectively directing the incident light to DMD chip, the expected image is projected following the light beam reflected by DMD chip.
Application
Applied in DLP® projection system, light path is changed by using TIR to save the space in optical engine and enhance contrast level of the system.
