A
Active matrix 
 
This is a kind of liquid crystal display structure in which switching tr\
ansistors are attached to each 
pixel to control the on/off voltage. It produces a brighter and sharper \
display with a broader viewing 
angle than a passive matrix display. Also refer to TFT (thin film trans\
istor).

A semiconductor material that is used to make the thin film...

Glossary
The light source for a transmissive LCD. There are two techniques used i\
n nowaday LCD designs. 
Most TFT LCD panels use CCFLs (cold cathode fluorescent light) and a d\
iffuser panel directly 
behind the liquid crystal layer. New technology using Light Emitting Dio\
des (LED) are still under 
development.
 
Brightness
The dimension of color that is referred to an achromatic scale, ranging \
from black to white, also 
called lightness or luminous reflectance. Because of confusion with satu\...

Glossary
Contrast
The luminance variation between light and dark areas in an image.
 
Contrast ratio
The ratio of luminance between the brightest white pattern and the darke\
st black pattern.

Energy Star Computers Program 
An energy conservation program launched by the US Environmental Protecti\
on Agency (EPA), 
promotes the manufacture and marketing of energy-efficient office automa\
tion equipment. 
Companies joining this program, must be willing to commit themselves to \
manufacture one or more 
products capable of going into a low -power state (< 30 W) either afte\
r a period of inactivity, or after 
a predetermined time selected by the...

Such a series may be made up of steps, which appear to be equally distan\
t from one another. If the 
Analog/ Digital converter is 8 bit, then the monitor can display at most\
 2
8 = 256 levels. For a color 
monitor, R.G.B. each color hads 256 levels. Thus, total color can displa\
y is 256x256x256= 16.7 
million.
 
 
H 
Hue
The main attribute of a color that distinguishes it from other colors. F\
or example, a color may have a 
green, yellow, or purple hue. Color defined as having hue are know...

Luminance
A measure of the brightness or luminous intensity of light, usually expr\
essed in units of Candelas 
per square meter (cd/m2) or foot Lamberts. 1 fL=3.426 cd/m2.

N
Nit
A unit of luminance equal to 1 cd/m2 or 0.292 ftL.
P
Pixel
PICture Element; the smallest element on a computerized CRT or LCD image\
, and hence a display.
 
Polarizer
A light filter which only allows light waves of a certain rotation throu\
gh. Polarized material with

Glossary
Refresh rate
The number of times per second the screen is refreshed or redrawn. This \
number is usually stated 
in Hz (Hertz) or cycles per second. A rate of 60 Hz is equal to 60 tom\
es per second.
 
S 
 
SmartContrast 
Unique technology that dynamically analyzes displayed content and automa\
tically optimizes a LCD 
monitors contrast ratio for maximum visual clarity and viewing enjoymen\

Glossary
Attachment points are referred to as ports. Each hub converts a single a\
ttachment point into 
multiple attachment points. The architecture supports concatenation of m\
ultiple hubs. 
The upstream port of a hub connects the hub towards the host. Each of th\
e other downstream ports 
of a hub allows connection to another hub or function. Hubs can detect, \
attach and detach at each 
downstream port and enable the distribution of power to downstream devic\
es. Each downstream 
port can be...
