this device gernerate about 1,500~2,000V.

- AC Adapter

Device that converts AC(90V~240V) to DC

(+12V or 14V)

- SMPS(Switching Mode Power Supply)

Switching Mode Power supply. This design

technology is used to step up/down the

input power by switching on/off

- FRC(Frame Rate Controller)

Technology that change image frame quantity

displayed on screen for one second.

Actually TFT-LCD panel require 60 pcs of

frame for one second.

so,this technology is needed to convert input

image to 60 pcs regardless input frame quantity.

- Image Scaler

Technology that convert various input resolution to

other resolution.(ex. 640* 480 to 1024*768)

- Auto Configuration(Auto adjustment)

This is an algorithm to adjust monitor to optimum

condition by pushing one key.

- OSD(On Screen Display)

On screen display. customer can control

the screen easily with this.

- Image Lock

This means "Fineness adjustment" in

LCD Monitor, the features are "Fine" and "Coarse"

- FINE

"Fine" adjustment is used to adjust visibility by

control phase difference.

- COARSE

This is a adjustment by tuning with Video colck

and PLL clock.

- DVI (Digital Visual Interface)

This provides a high speed digital connection

for visual data types that is display technology

independent. this interface is primarily forcused

at providing a connection between a computer

and its display device.

- L.V.D.S.(Low Voltage Differential Signaling)

a kind of transmission method for Digital.It can

be used from Main PBA to Panel.

- T.M.D.S
(Transition minimized Differential Signaling)

a kind of transmission method for Digital.

It can be used from Video card to Main PBA.

- DDC(Display data channel)

It is a communication method between

Host Computer and related equipment.

It can make it Plug and Play between

PC and Monitor.

- EDID

Extended Display Identification Data PC can

recognize the monitor information as Product

data, Product name,Display mode,Serial

number and Signal source,etc through DDC

Line communicating with PC and Monitor.

- Dot Pitch

The image on a monitor is composed of red, green
and blue dots. The closer the dots, the higher the
resolution. The distance between two dots of the
same color is called the 'Dot Pitch'. Unit: mm

- Vertical Frequency

The screen must be redrawn several times per
second in order to create and display an image
for the user. The frequency of this repetition per
second is called Vertical Frequency or Refresh
Rate. Unit: Hz

Example: If the same light repeats itself 60 times

per second, this is regarded as 60 Hz.

- Horizontal Frequency

The time to scan one line connecting the right
edge to the left edge of the screen horizontally is
called Horizontal Cycle. The inverse number of the
Horizontal Cycle is called Horizontal Frequency.
Unit: kHz

- Interlace and Non-Interlace Methods

Showing the horizontal lines of the screen from
the top to the bottom in order is called the
Non-Interlace method while showing odd lines
and then even lines in turn is called the Interlace
method. The Non-Interlace method is used for the
majority of monitors to ensure a clear image.
The Interlace method is the same as that used
in TVs.

- Plug & Play

This is a function that provides the best quality
screen for the user by allowing the computer and
the monitor to exchange information automatically.
This monitor follows the international standard
VESA DDC for the Plug & Play function.

- Resolution

The number of horizontal and vertical dots used
to compose the screen image is called 'resolution'.
This number shows the accuracy of the display.
High resolution is good for performing multiple
tasks as more image information can be shown on
the screen.

Example: If the resolution is 1280 x 1024 , this

means the screen is composed of 1280 horizontal
dots (horizontal resolution) and 1024 vertical lines
(vertical resolution).

- DVD

A type of digital disk technology that takes up only
the benefits of CD and LD, to implement a high
resolution/quality, which enables the user to enjoy
clearer images.

- DTV

Broadcasting (Digital TV Broadcasting)
An enhanced broadcasting technology to process
digital video signals using a set-top box, which
implements a high resolution and clearer digital
images on the screen.

- A2

This system uses two carriers to transmit voice
data. Countries such as South Korea and
Germany use this system.

- BTSC

Broadcast Television System Committee
The stereo broadcasting system that is used in
most of the countries that have adopted the NTSC
system, including the United States, Canada,
Chile, Venezuela and Taiwan. It also refers to the
organization that has been organized to promote
its development and management.

- EIAJ

Electronic Industries Association of Japan.

- RF Cable

A round signal cable generally used for TV
antennas.

- Satellite Broadcasting

Broadcasting service provided via satellite.
Enables high picture quality and clear sound
throughout the country regardless of the location
of the viewer.

- Sound Balance

Balances the levels of the sound coming from
each speaker in televisions with two speakers.

- Cable TV

Whereas the terrestrial broadcasting is delivered
via frequency signals through the air, cable
broadcasting is transmitted via a cable network.
In order to view cable TV, one must purchase a
cable receiver and hook it up to the cable network.

- CATV

"CATV" refers to the broadcasting service offered
at hotels, schools and other buildings through their
own broadcasting system, apart from VHF or UHF
broadcasting by terrestrial broadcasters.
The CATV programs may include movies,
entertainment and educational programs.
(Different from cable TV.)
CATV can be viewed only within the area in
which the CATV service is offered.

- S-Video

Short for "Super Video." S-Video allows up to 800
lines of horizontal resolution, enabling high-quality
video.

- VHF/UHF

VHF indicates TV channels 2 to 13, and UHF

indicates channels 14 through 69.

- Channel Fine Tuning

This feature allows the viewer to fine-tune the TV
channel to obtain the best viewing conditions. The
Samsung LCD TV has both automatic and manual
channel fine-tuning features to enable the viewer
to adjust their desired settings.

- External Device Input

External device input refers to video input from
such external video device as VCR, camcorder
and DVD player, separate from a TV broadcast.

- LNA (Low Noise Amplifier)

This derives from artificial satellite technology that
amplifies weak signals even in poor reception
areas for sharper images.

- Antenna Converter

A connection part that is used to link a wide

antenna cable (feeder cable) to the TV.

- English Caption (= Caption Setting)

A kind of language selection feature that provides
English subtitles (caption) or character information
services from broadcasting services (ex: AFKN) or
video tapes (marked CC), and which are especially
useful for studying English.
