Dot Pitch

The image on a monitor is composed of red, green and blue

 

dots. The closer the dots, the higher the resolution. The dis-

 

tance 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 fre-

 

quency of this repetition per second is called the Vertical

 

Frequency or Refresh Rate. Unit: Hz

 

Example: If the same light repeats itself 60 times per sec-

 

ond, 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 the Horizontal

 

Cycle. The inverse number of the Horizontal Cycle is called

 

Horizontal Frequency. Unit: kHz
