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

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).
