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
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.

adjustment)
This is an algorithm to adjust monitor to optimum condition by pushing one key.
OSD(On Screen Display)
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 clock 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).
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 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, 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.

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 devices as VCRs, camcorders and DVD players, separate from a TV broadcast.
