The detailed design specifications of each of these subassemblies are provided in SUbsequent
subsections of this document The most important design archrtecture aspects are:
1. The light projection architecture utilizes a two-fold configuration that allows for achieving a
minimal depth chassis design.
2. The main enclosure mechanical design concept has as few as possible mechanical components
to hetp in reducing the tooling cost and the assembly cost of the chassis.
3. The main enclosure mechanical design concept allows the main assemblies to be used with
multiple front-view assemblies to offer different aesthetic look industrial designs with different
screen
sIZes.
4. In order to allow for competitive procurement of the most costly subassembly, the main enclosure
is designed to allow for the use of optical engines from at least two different optical engine
supphers
5. In order to provide AKAI with the ability to address different
d~tribution
channels ',·. • th a different
aesthetic look and screen size designs, the main enclosure is designed such tr,at it allows
mounting of the optical engine platfonm in such a way to accommodate the throw distances for
sizes ranging from a 42" diagonal screen to a 46" diagonal screen.
S The Formatter Board, which provides the video and graphics for display on the screen, features:
Low-voltage differential signal (LVDS) video input interface for reduced EMI emission .
• Cost effective Single Board Design
