DISPLAY DEVICES
● The display device is an output device used to represent the information in
the form of images (visual form).
● Display systems are mostly called a Video monitor or Video Display Unit
(VDU).
● Display devices are designed to model, display, view, or display information.
● The purpose of display technology is to simplify information sharing.
CATHODE RAY TUBE(CRT)
CRT is a technology used in traditional computer monitors and televisions.
● The image on CRT display is created by firing electrons from the back
of the tube of phosphorus located towards
the front of the screen.
● Once the electron heats the phosphorus, they
light up, and they are projected on a screen.
● The color which is viewed on the screen is
produced by a blend of red, blue and green light.
COMPONENTS OF CRT
ELECTRON GUN
DEFLECTION YOKE
CONTROL ELECTRODE
PHOSPHORUS-COATED SCREEN
FOCUSING SYSTEM
ELECTRON GUN
Electron gun is defined as
the source of focused and
accelerated electron beam.
It is a device used in Cathode Ray
Tube for displaying the image on the
phosphorous screen of CRT.
The electron gun emits electrons and
forms them into a beam by the help of
a heater, cathode, grid, pre-
accelerating, accelerating and
focusing anode.
DEFLECTION YOKE
A deflection yoke is a kind of
magnetic lens, used in cathode
ray tubes to scan the electron
beam both vertically and
horizontally over the whole
screen.
FOCUSING SYSTEM
It is used to create a clear picture
by focusing the electrons into
a narrow beam.
DEFLECTION YOKE
A deflection yoke is a kind of
magnetic lens, used in cathode
ray tubes to scan the electron
beam both vertically and
horizontally over the whole
screen.
PHOSPHORUS-COATEDSCREEN
On the inside the CRTs are coated with a
phosphor layer that, when bombarded
with electron beams, converts the kinetic
energy of the electrons into light
radiation. Different compositions of
phosphor produce different colors. This
is defined as the phosphor spectral
characteristic.
