Before revision: How 3LCD technology works Creating Colors from White Light:A projector using 3LCD technology works by first splitting the white light from the lamp into its three primary colors of red, green and blue by passing the lamp light through special dichroic filter / reflector assemblies called “dichroic mirrors.” Each dichroic mirror only allows specific colored wavelengths of light to pass through while reflecting the rest away.
