14-1 Technical Terms

- TFT-LCD

(Thin film Transistor Liquid Crystal Display)

ADC(Analog to Digital Converter)

This is a circuit that converts from analog signal to

digital signals.

- 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.

- PLL(Phase Locked Loop)

During progressing ADC, Device makes clock syn-

chronizing HSYNC with Video clock

- Image Lock

This means "Fineness adjustment" in LCD

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

- Inverter

Device that supply Power to LCD panel lamp. this

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

- FINE

"Fine" adjustment is used to adjust visibility by

control phase difference.

- AC Adapter

Device that converts AC(90V~240V) to DC(+12V

or 14V)

- COARSE

This is a adjustment by tuning with Video colck

and PLL clock.

- SMPS(Switching Mode Power Supply)

Switching Mode Power supply. This design tech-

nology is used to step up/down the input power by

switching on/off

- 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.

- FRC(Frame Rate Controller)

Technology that change image frame quantity dis-

played 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.

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

a kind of transmission method for Digital.It can be

used from Main PBA to Panel.

- Image Scaler

Technology that convert various input resolution to

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

- DVI (Digital Visual Interface)

This provides a high speed digital connection for

visual data types that is display technology inde-

pendent. this interface is primarily forcused at pro-

viding a connection between a computer and its

display device.

- 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.

- 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.

- 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.

- 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.

- EDID

Extended Display Identification Data PC can rec-

ognize the monitor information as Product data,

Product name,Display mode,Serial number and

Signal source,etc through DDC Line communicat-

ing with PC and Monitor.

- 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).

- 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 sec-

ond 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.

- 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.

- 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

- EIAJ

Electronic Industries Association of Japan.

- RF Cable

A round signal cable generally used for TV antennas.

14 Reference Infomation

- Satellite Broadcasting

Broadcasting service provided via satellite.

Enables high picture quality and clear sound

throughout the country regardless of the location of

the viewer.

- 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.

- Sound Balance

Balances the levels of the sound coming from

each speaker in televisions with two speakers.

- External Device Input

External device input refers to video input from

such external video devices as VCRs, camcorders

and DVD players, separate from a TV broadcast.

- Cable TV

Whereas the terrestrial broadcasting is delivered

via frequency signals through the air, cable broad-

casting 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, entertain-

ment 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 indi-

cates channels 14 through 69.
