Single-Panel Liquid Crystal Optical Engine for Rear Projectors
For the availability of this product, please contact the sales office.
Description
The DS001AKA is a single-panel liquid crystal
optical engine for use in rear projectors, capable of
full-color displays without color filters (CF).
This engine provides a wide aspect ratio of 16:9,
such as those represented in HD.
The side-black function also allows an aspect ratio
of 4:3 in the NTSC/PAL mode. 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 30" to 60" 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: 768,000
Horizontal resolution: 600 TV lines
NTSC/NTSC-WIDE/HD (band: 20MHz) mode selectable (PAL/PAL-WIDE mode also available through
conversion of scanned dot numbers by an external IC)
Up/down and/or right/left inverse display function
Side-black function
16:9 and 4:3 aspect-ratio switching 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 (531mm/37", at 4.5% overscanning)
Image distortion correction floating mechanism to support 30" to 60"
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 (LCX011AM)
Dots
16:9 display: 1599.5 (H) × 480 (V) = 767,760 dots
4:3 display: 1199.5 (H) × 480 (V) = 575,760 dots
Wide fixed focal length lenses for enlarged projection of LCD
Silent fans for cooling

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 System I.
CR = L (White)
L (Black)
2. Luminous flux
In measurement system I, the average of the luminance at the nine points specified in ANSI standards when
the input signal amplitude VAC is 0.5V, multiplied by the effective display area, is computed.
L = average illuminance at nine ANSI points (lm/m2) × effective display 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
H
3. Chromaticity
Raster modes of each color are defined by the representations at the input signal amplitude conditions shown
in the table below.
System I uses chromaticity of x and y on the CIE standards here.
Signal amplitude (VAC) supplied 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 uniformity
In the measurement system I, the maximum values of the 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 uniformity.
Wx = x max – x min
Wy = y max – y min
For other electro-optical characteristics, refer to the LCX011AM specifications.
