MY PRESENTATION TOPICS IS OUTPUT
DEVICE
WHAT IS

AN
OUTPUT DEVICE ?
An output device is any piece of computer
hardware equipment used to communicate the
results of data processing carried out by an
information processing system (such as a
computer) to the outside world.
THE OUTPUT DEVICES ARE:
Monitor
 Speaker
 Headphone
 Printer
 Plotter
 Projector

MONITOR
Monitor is a TV like device that display
information.
 It can display text as well as graphic images in
color or black & white while based on monitor
type.
 Monitors are classified on the basis of color and
signals.

THE CLASSIFICATION OF MONITOR
1. Based on color
2. Based on signals
BASED ON COLOR
Based on color monitor are three types:
They are: Monochrome
 Gray-scale
 Multi color
MONOCHROME
It display two color, one on the forge round and one on
the background the colors can be black and white, green
and black and amber and black.
GRAY-SCALE
Special type of monochrome Monitor capable of display
different Shades of gray.
MULTI-COLOR
They are called RGB monitor. They accept three
separate signals Red, Green and Blue. A multi-color
monitor can display any color.
BASED ON SIGNALS
Based on signs monitor are two types:
 Digital Monitor
 Analog Monitor
DIGITAL MONITOR
It accepts digital signals rather than analog.
 The term digital refers to the type of input
received from the video adapter.
 Digital monitors are fast and produce clear
images.
Ex: Flat-panel display which uses Liquid Crystal
Display technology.

ANALOG MONITOR
This is the traditional type of color display that
has been used for years in televisions.
 In reality all monitors based on CRT(Cathode
Ray Tube) technology are analog.
 The monitor consumes much space.

SOME ANALOG MONITOR
Flat Panel Display : For laptop computers more
compact, low-power, and durable monitors are
used, A number of flat-panel display technology are
available for this. The most common are the
plasma and liquid crystal display.
Plasma Display: A Plasma display consists of
ionized near argon gas (plasma) sealed between
two glass plates. One plate encase a set of vertical
wires. Pixel are formed by the intersection of the
horizontal and vertical wires.
CRT: Liquid crystal display have been used for several
years in calculators and digital watches. A thin layer of
liquid crystal substance is suspended between two thin
sheets in polarized gloss and separated by a wire grade
into tiny squares. As current is applied to the wires the
liquid crystal substance within the square changes from
clear to opaque or black. The thousands of clear and
black squares produce palters of characters.
