Light Source
Mercury-free LED (up to 20000 hours in Normal

NOTE: The LED life rating for any projector is a measure of
brightness degradation only, and is not a specification for the time it
takes a LED to fail and cease light output. LED life is defined as the
time it takes for more than 50 percent of a LED sample population
to have brightness decrease by approximately 50 percent of the
rated lumens for the specified LED. The LED life rating is not
guaranteed in any way. The actual operating life span of a projector
LED will vary according to operating conditions and usage patterns.
Usage of a projector in stressful conditions which may include dusty
environments, under high temperatures, many hours per day, and
abrupt powering-off will most likely result in a LED’s shortened
operating life span or possible LED failure.

Appendix: Glossary
ANSI Lumens — A standard for measuring the brightness. It is calculated by
dividing a square meter image into nine equal rectangles, measuring the
lux (or brightness) reading at the center of each rectangle, and averaging
these nine points.
Aspect Ratio — The most popular aspect ratio is 4:3 (4 by 3). Early
television and computer video formats are in a 4:3 aspect ratio, which
means that the width of the image is 4/3 times the height.
Brightness — The amount of light emitted from a display or projection
display or projection device. The brightness of projector is measured by
ANSI lumens.
Color Temperature — The color appearance of white light. Low color
temperature implies warmer (more yellow/red) light while high color
temperature implies a colder (more blue) light. The standard unit for color
temperature is Kelvin (K).
Compressed Resolution — If the input images are of higher resolution
than the native resolution of the projector, the resulting image will be
scaled to fit the native resolution of the projector. The nature of
compression in a digital device means that some image content is lost.
Contrast Ratio — Range of light and dark values in a picture, or the ratio
between their maximum and minimum values. There are two methods
used by the projection industry to measure the ratio:
1 Full On/Off — measures the ratio of the light output of an all white image
(full on) and the light output of an all black (full off) image.
2 ANSI — measures a pattern of 16 alternating black and white rectangles.
The average light output from the white rectangles is divided by the
average light output of the black rectangles to determine the ANSI contrast
ratio.
Full On/Off contrast is always a larger number than ANSI contrast for the
same projector.
dB — decibel — A unit used to express relative difference in power or
intensity, usually between two acoustic or electric signals, equal to ten
times the common logarithm of the ratio of the two levels.
Diagonal Screen — A method of measuring the size of a screen or a
projected image. It measures from one corner to the opposite corner. A 9

Glossary
FT high, 12 FT wide, screen has a diagonal of 15 FT. This document
assumes that the diagonal dimensions are for the traditional 4:3 ratio of a
computer image as per the example above.
DLP® — Digital Light Processing™ — Reflective display technology
developed by Texas Instruments, using small manipulated mirrors. Light
passing through a color filter is sent to the DLP mirrors which arrange the
RGB colors into a picture projected onto screen, also known as DMD.
DMD — Digital Micro-Mirror Device — Each DMD consists of thousands of
tilting, microscopic aluminum alloy mirrors mounted on a hidden yoke.
Focal Length — The distance from the surface of a lens to its focal point.
Frequency — It is the rate of repetition in cycles per seconds of electrical
signals. Measured in Hz (Hertz).
HDCP — High-Bandwidth Digital-Content Protection — A specification
developed by Intel™ Corporation to protect digital entertainment across
digital interface, such as DVI, HDMI.
HDMI — High-Definition Multimedia Interface — HDMI carries both
uncompressed high definition video along with digital audio and device
control data in a single connector.
Hz (Hertz) — Unit of frequency.
Keystone Correction — Device that will correct an image of the distortion
(usually a wide-top narrow-bottom effect) of a projected image caused by
improper projector to screen angle.
Maximum Distance — The distance from a screen the projector can be to
cast an image that is usable (bright enough) in a fully darkened room.
Maximum Image Size — The largest image a projector can throw in a
darkened room. This is usually limited by focal range of the optics.
Minimum Distance — The closest position that a projector can focus an
image onto a screen.
NTSC — National Television Standards Committee. North American
standard for video and broadcasting, with a video format of 525 lines at 30
frames per second.
PAL — Phase Alternating Line. A European broadcast standard for video
and broadcasting, with a video format of 625 lines at 25 frames per second.
Reverse Image — Feature that allows you to flip the image horizontally.
When used in a normal forward projection environment text, graphics, etc.
are backwards. Reverse image is used for rear projection.
SVGA — Super Video Graphics Array — 800 x 600 pixels count.
Glossary

SXGA — Super Extended Graphics Array, — 1280 x 1024 pixels count.
UXGA — Ultra Extended Graphics Array — 1600 x 1200 pixels count.
VGA — Video Graphics Array — 640 x 480 pixels count.
XGA — Extended Video Graphics Array — 1024 x 768 pixels count.
WXGA — Wide Extended Graphics Array — 1280 x 800 pixels count.
Zoom Lens — Lens with a variable focal length that allows the operator to
move the view in or out making the image smaller or larger.
Zoom Lens Ratio — Is the ratio between the smallest and largest image a
lens can project from a fixed distance. For example, a 1.4:1 zoom lens ratio
means that a 10 foot image without zoom would be a 14 foot image with
full zoom.
