Sync Signal
Sync (Synchronized) Signals refer to the standard signals that are required to display desired colors on the monitor. They are divided into Vertical and Horizontal Sync Signals. These signals display normal color images by the set resolution and frequency.
Types of Sync Signals
| Separate |
| This is a scheme of transmitting individual vertical sync signals to the monitor. |
|
|
|
|
Composite | This is a scheme of combining vertical sync signals into one composite signal | ||
|
|
| and transmitting it to the monitor. The monitor displays the color signals by |
|
|
| separating the composite signal into original color signals. |
|
|
|
|
Sync On Green | This scheme does not use sync signals. Instead, it combines horizontal and | ||
|
|
| vertical sync signals into a Green signal and transmits to the monitor. It is mainly |
|
|
| used for workstations. |
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
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
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).
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.
