Single-Panel Liquid Crystal Optical Engine for Rear Pr ojectors
Description
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
image distortion.
A high intensity discharge (HID) lamp ensures high
luminance and low power consumption.
Features
• The number of active dots: 576,000
• Horizontal resolution: 600 TV lines
• NTSC mode selectable (PAL mode also available through conversion of scanned dot numbers by an
external IC)
• Up/down and/or right/left inverse display function
• Full-color display with CF-less projection system
• High luminouce flux: normally-white 120 ANSIlm (typ.)
• Ultra-wide angle lenses for short projection distances (646mm/40", at 4.5% overscanning)
• Image distortion correction floating mechanism to support 27" to 55"
• Relative illumination: 70% or above
• Uses HID lamp (100W)
Preliminary
Engine Configuration
• HID lamp
• Lamp driver (DC 300V input)
• High-efficiency illumination system employing glass rods
• Separate RGB illumination systems using dichroic mirrors (DM)
• LCD panel mounting mechanism, adjustable along XYθ axes
• LCD panel (LCX019AM)
Dots
1199.5 (H) × 480 (V) = 575,760 dots
• Wide fixed focal length lenses for enlarged projection of LCD
• Silent fans for cooling

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.
