DS005AKA
Single-Panel Liquid Crystal Optical Engine for Rear Projectors
For the availability of this product, please contact the sales office.
Description
The DS005AKA is a single-panel liquid crystal
optical engine for use in rear projectors, and is
capable of full-color displays without color filters (CF).
The DS005AKA employs a square pixel arrangement
optimal for data projector applications, and allows
clear graphic and character displays. Up/down and/or
right/left inversion functions accommodate various
mounting methods.
Short projection distances are made possible through
the adoption of an ultra-wide angle lens. In addition, a
projection lens floating mechanism delivers 40" to 50"
projected images with minimal image distortion.
A high intensity discharge (HID) lamp ensures high
luminance and low power consumption.
Features
Number of active dots: 1,456,000
Horizontal resolution: 600 TV lines
Supports SVGA (804 × 3 × 604)/PC98(804 × 3 × 500) mode display
NTSC/NTSC-WIDE/PAL/PAL-WIDE modes 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 luminance: normally-white 200 ANSIlm (typ.)
Ultra-wide angle lens for short projection distances (592.8mm/39.8")
Image distortion correction floating mechanism to support 40" to 50"
Relative luminance: 70% or more
Uses HID lamp (100W)
"PC98" is a trademark of NEC Corporation.
Engine Configuration
HID lamp
Lamp driver (DC 300V input)
High-efficiency illumination system employing an integrator
Separate RGB illumination systems using dichroic mirrors (DM)
LCD panel mounting mechanism, adjustable along XYθ axes
LCD panel (LCX021BM)
Dots: 2412 (H) × 604 (V) = 1,456,848 dots
Wide fixed focal length lens for enlarged projection of LCD
Applications
Liquid crystal rear projection TV/monitor
