Single-Panel Liquid Crystal Optical Engine for Rear Projectors

Sony Semiconductor 

DS005AKA

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.
