DS002AKA
Single-Panel Liquid Crystal Optical Engine for Rear Projectors Preliminary
For the availability of this product, please contact the sales office.
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)
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

1. Focus adjustment
Loosen the screws (four) holding the projection lens in place, and adjust the eccentricity roller for focus
adjustment to change the focus between 27" to 55".

Projection distance [nm]
∗1 The projection distance is the distance from the front edge of the projection lens to the screen.
2. Floating mechanism
The floating mechanism corrects for distortion between 27" to 55". At time of shipment, it is optimized for a
diagonal of 40" (including 4.5% overscan), but the floating mechanism should be adjusted if the projection size
is different and image distortion becomes prominent. Recommended values for different projection sizes are
given below, but adjustments should be made such that image distortion is minimized.
