Single-Panel Liquid Crystal Optical Engine for Rear Projectors
Description
The DS005AKC 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 DS005AKC 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
type 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 type)
• Image distortion correction floating mechanism to support 40 to 50 type
• 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
