Sony DS001AKA Datasheet

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

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.
