DS005AKC Datasheet, PDF (2/12 Pages) Sony Corporation – Single-Panel Liquid Crystal Optical Engine for Rear Projectors

DS005AKC
Description of Basic Operation
• Apply DC 300V to the lamp driver.
• Light emitted by the lamp is focused by an elliptical reflector and is converted to an approximately collimated
ray by a relay lens.
• After that the light passes through the polarizer conversion system elements and an optical integrator.
• Light output from the optical integrator passes through a Fresnel lens to become a collimated ray, which is
color-separated by a group of dichroic mirrors.
• The color-separated rays illuminate the LCX021BM evenly, and are focused on the respective RGB dots by
microlenses mounted on the LCX021BM and distributed.
• After transmitting the panel, the light is enlarged and projected onto a screen by a projection lens.
For details of the LCD panel operation, see the LCX021BM specifications.
