Cathode Ray Tube
Cathode Ray Tube is Commonly called CRT
Tube. It is a Vacuum Tube which has Electron gun and also a
fluorescent screen where the beam strikes. There X-X plates
and Y-Y Plates for beam deflection. This section is called
Deflecting section. Now Flat panel Displays and Liquid Crystal
Displays Have replaced CRT's.
First the electron beam is thrown by
electron guns which is then focused and deflected and we see
it on the phosphor coated screen. In Televisions entire area
of Vacuum Tube is scanned line by line called raster scan. In
random scan only those areas are beamed where we need the
picture from the buffer.
