Raster Scan
Raster Scan Technique
This is the universally accepted one used in CRT displays of the PC's. This technique the horizontal and vertical deflection signals are generated to move the beam in forward and backward direction across the screen like a raster. The retrace portion of the raster scan pattern is suppressed (blanked) by reducing the intensity of the electron beam during the time of retrace. The complete CRT screen canbe considered to be made of hundreds of dots commonly knownas pixels. Any pixel can be illuminated by the electron beam during the raster process or it can be blanked by reducing the intensity of the electron beam.
