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

1. Contrast ratio
Contrast ratio (CR) is given by the following formula.
L (White): Surface illuminance of the screen at the input signal amplitude VAC = 0.5V.
L (Black): Surface illuminance of the screen at VAC = 4.5V.
Both luminances are measured by Measurement System I.
CR = L (White)/L (Black)
2. Luminous intensity
In Measurement System I, the average of the illuminance at the nine points specified in the ANSI standards
when the input signal amplitude VAC is 0.5V, multiplied by the projection area, is computed.
L = average illuminance at nine ANSI points (lm/m2) × projection area (m2)
H/3 H/3 H/3
Nine ANSI points: centers of each of the
areas obtained by dividing
the effective display area
into nine smaller areas

3. Chromaticity
Raster modes of each color are defined by the representations at the input signal amplitude conditions shown
in the table below. Measurement System I uses chromaticity of x and y of the CIE standards here.
Signal amplitude (VAC) applied to each input
R input
G input
B input
R 0.5 4.5 4.5
G 4.5 0.5 4.5
B 4.5 4.5 0.5
(Unit: V)
4. Color shading
In Measurement System I, the maximum values of CIE color differences at the three points in the middle row
of the nine ANSI points, measured at an input signal amplitude VAC of 0.5V, are used to compute the color
shading.
∆u'v' = (u'1 – u'2)2 + (v'1 – v2)2
