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)

DS001AKA

Explanation of Basic Operation

• Apply DC 300V to the lamp driver.

• Light emitted by the lamp is focused by an elliptical reflector on a glass rod integrator, and is rendered

homogeneous at the output end of the integrator.

• Light output from the integrator passes through a relay lens and collimator lens to become a collimated ray,

which is color-separated by a group of dichroic mirrors.

• The color-separated rays are focused on the respective RGB dots by microlenses mounted on the

LCX011AM, and distributed.

• After transmitting the panel, the light is enlarged and projected onto a screen by a projection lens.

For details of the LCD panel operation, please refer to the LCX011AM specifications.

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.

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

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.

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 30" to 60". At time of shipment, it is optimized for a

diagonal of 37" (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.

Notes on Handling

(1) Cooling

1) This optical engine is provided with DC fans to cool the panel and lamp unit. However, the set should

be designed for enough ventilation and convection to ensure sufficient cooling.

2) The lamp should under no circumstances be lit while the cooling DC fans are not operating. The

cooling DC fans are provided with sensor output pins to detect operation, and the lamp driver is

provided with start control input pins. The set should be designed so that if the cooling fans are not

operating, the lamp driver does not operate.

3) When using a dust filter with ventilation orifices, reduced ventilation due to filter clogging can cause

rises in temperature, possibly damaging the LCD or other components. The temperature of the optical

engine should be controlled, and filters should be changed as appropriate.

(2) Lamp unit

1) In order to prevent burns and other accidents, do not directly touch the lamp housing while the lamp is

lit or immediately after it has been extinguished.

2) Because of the extremely high focusing power of the ellipsoid reflector, if it is not installed in the

specified position, damage to the engine or other problems may arise. Ensure that, if the lamp housing

is not mounted in the specified position when changing the lamp, the lamp power supply will not

operate.

3) Always use the included lamp driver to light the lamp. If the lamp is turned on and off repeatedly in

short cycles, the lamp lifetime will be shortened.

4) The lamp is designed to be lit in a horizontal position. Ensure that the optical axis of the ellipsoid

reflector is within ±20° of horizontal.

5) The lamp emits ultraviolet rays while lit and immediately after being extinguished. Be sure not to look

directly at the lamp.

(3) Protection from dust and dirt

Image quality is significantly degraded by dust in the optical engine. Employ a set construction such that

after dust is removed by a filter or other means during air cooling, air is blown into the optical engine.

1) Operate in clean environment.

2) Do not touch the surface of a projection lens and polarizer. The surfaces are easily scratched. When

cleaning, use a clean-room wiper with isopropyl alcohol. Be careful not to leave stains on the surface.

3) Use ionized air to blow off dust at an optical engine.

(4) Static charge prevention

1) Use non-chargeable gloves, or simply use bare hands.

2) Do not touch any electrodes.

3) Wear non-chargeable clothes and conductive shoes.

4) Keep optical engines away from any charged materials.

5) Use ionized air or some other means to discharge.

– 10 –

DS001AKA

(5) Other handling precautions

1) The DM angles of this optical engine are adjusted to their optimal values, and should not be changed.

2) Do not remove or take apart the engine cover, projection lens, projection lens mount, relay lens,

integrator support, or lamp housing.

3) Light emitted from the lamp and from the projection lens may harm the eyes. Do not look directly into

the light from the lamp or lens.

4) Do not drop an optical engine.

5) Do not twist or bend an optical engine.

6) Keep an optical engine away from heat source.

7) Do not dampen an optical engine with water or other solvents.

8) Avoid to store or to use an optical engine in high temperature or in high humidity, which may result in

optical engine damages.
