Single-Panel Liquid Crystal Optical Engine for Rear Projectors

Sony Semiconductor 

DS001AKA

Explanation of Basic Operation

• Apply DC 300V to the lamp driver.

• Light emitted by the lamp is focused by an elliptical reflector on a glass rod integrator, and is rendered

homogeneous at the output end of the integrator.

• Light output from the integrator passes through a relay lens and collimator lens to become a collimated ray,

which is color-separated by a group of dichroic mirrors.

• The color-separated rays are focused on the respective RGB dots by microlenses mounted on the

LCX011AM, 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, please refer to the LCX011AM specifications.
