DLP® technology |
For each individual pixel,
DLP® (Digital Light Processing) projectors use
tiny mirrors that are mounted on the Digital micro
mirror Device (DLP® chip) and tilt in response to
an electric signal. A DLP® chip's micro mirrors
are mounted on tiny hinges that enable them to
tilt either towards the light source in a DLP®
projection system (ON) or away from it (OFF).
This creates a light or dark pixel on the projection
surface. To generate a colour picture, 1-chip
DLP® projectors use a quickly rotating colour
wheel that projects the primary colours one after
the other.

Eco mode |
Eco mode is an environmentally
friendly function designed to save energy.
This function is useful in situations where the full
amount of brightness offered by the projector is
not needed. Reducing brightness by around 20%
decreases power consumption, minimises fan
noise and significantly prolongs lamp life.

Freeze |
This function allows the user to freeze
the projected image at any time, for example to
modify the contents of a presentation without
the audience noticing and then show it at a later
stage.

Image resolution |
The number of pixels,
horizontally and vertically, defines the resolution.
It is expressed as width x height. The principal
image resolution formats are S-VGA: 800 x 600
pixels, XGA: 1,024 x 768 pixels, S-XGA+: 1,400 x
1,050 pixels, Full HD: 1,920 x 1,080 pixels and W-
XGA. The more pixels an image contains, the
richer its detail. The ratio between the horizontal

Inorganic panel |
Inorganic LCD panels ensure
striking picture quality, because they allow an
even more natural colour reproduction. The
particularly deep black value and the related
contrast ratio guarantee impressive images. The
reduced border thickness of the individual pixels
increases the light output, which boosts image
brightness. Inorganic LCD panels absorb fewer
UV rays, thereby significantly increasing their
service life.

Interchangeable lenses |
Interchangeable lenses
are available as an option for many projectors.
They provide a particularly flexible response to
the presentation environment and requirements.
Wide-angle, standard and telephoto lenses are
available for a broad range of throw ratios.

Keystone correction |
Keystone is a trapezoidal
distortion of an image caused by projecting at a
steep vertical or horizontal angle. The electronics
behind modern data and video projectors can
correct this distortion to produce a rectangular
image display. The Keystone correction function
can be set automatically or manually, or it can be
disabled.

Lens shift |
Projecting an image vertically and
horizontally causes trapezoidal distortion of the
image. The Lens shift function allows the
position of the lens to be varied both vertically
and horizontally to correct the distortion. The
resolution and image geometry are fully retained.

MyLogo function |
Give your presentations an

screen appearing between presentations or
when the projector is turned on, you can set
individual logos or images to display, and secure
this setting using a PIN code.

Network capability/W-LAN |
Including projectors
in a network offers numerous advantages – for
example, it allows projectors to be maintained
and configured over a company network or the
Internet. Problems are displayed automatically
and resolved faster. Because of the integrated W-
LAN connection between computer and
projector, there's no need to hook the projector
up using cables before a presentation can start.

the network to one or more projectors. In

QuaDrive® |
An additional fourth LCD panel
called the Color Control Device (CCD) separately
controls the amount of yellow light in the
projected image and increases the displayed
colour space by up to 20%. This allows for even
more realistic and vivid colour tones, especially in
the red and green ranges. The result is more
vibrant colours and higher image brightness.

Rear projection |
The projector is installed behind
the screen. It projects the image to a special rear
projection surface. A setting in the projector's on-
screen menu allows you to choose reversed
image display. Light beams are prevented from
being broken up in the presentation room,
thereby eliminating potential problems.

controls can be uniquely assigned to a specific

Security features |
Security features ensure that
the projector cannot be used or removed without
authorisation. They provide valuable protection
wherever numerous individuals have access to
the device – in the public sector, universities,
schools or the business world. SANYO projectors

Signal types |
Depending on the user's needs,
a projector can be connected to various image
sources, for example DVD player, AV/TV receiver
or PC. The following signals can be connected:
Composite (FBAS), S-Video, RGB, Component
(YUV) and digital signals.

Throw ratio |
The throw ratio specifies the ratio
between the projection distance and image
width; this depends on the lens being used.
Example: With a throw ratio of 2 : 1, for a
projection distance of 4 m the image width is
2 m. Since most lenses are equipped with an
optical zoom function, the throw ratio is given
in a range such as 1.5–2 : 1. This means that
an image width of 2 m can be displayed from
a distance of 3–4 m.
