Optical Engine. DS002AKA Datasheet
Single-Panel Liquid Crystal Optical Engine for Rear Projectors Preliminary
For the availability of this product, please contact the sales office.
The DS002AKA is a single-panel liquid crystal
optical engine for use in rear projectors, capable of
full-color displays without color filters (CF).
Up/down and/or right/left inversion functions
accommodate various mounting methods.
Short projection distances are made possible
through the adoption of ultra-wide angle lenses. In
addition, a projection lens floating mechanism
delivers 27" to 55" projected images with minimal
A high intensity discharge (HID) lamp ensures high
luminance and low power consumption.

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 LCX019AM specifications.
