What is?

Display output device is a device to visually present information, related to the touch, saved or sent in various forms.

An output of the equipment can menyampaiakan information visually. The information is usually displayed with a soft copy.


With the very rapid development, there are currently three types of technology monitor. The three classes of technologies are CRT (Cathode Ray Tube), Liquid Crystal Display (LCD) and plasma gas.

Directly touching the screen with a finger.
Weaknesses:
-Exhausting;
-Hands cover the screen;
-Hands away from the keyboard;
-The appointment is not precise;
-Screen can be dirty.


CRT

In the CRT monitor, the screen is used as a cathode ray tube. This technology automatically display on the monitor with the electrons to emit rays of a point on the screen. Rays will be strengthened to show the bright side and dark side to diperlemah.
CRT technology is the cheapest technology, compared with the other two technologies. However the resulting resolution is quite good for various purposes. The only electricity required is quite large and has a radiation elektromagnetik strong enough.
For example, television and computer monitors


LCD

LCD monitor is no longer using electron tubes, but use a similar liquid crystal that can be fluorescent. This technology produces a monitor that is known by the name of Flat Panel Display with the screen flat-shaped, and the ability of a higher resolution than the CRT. Because of the flat, the flat type of monitor by using the energy of small and widely used in portable computers.


Plasma Gas

Monitor this type of technology combines with a CRT monitor. With the resulting technology, able to create a screen-like LCD with flimsiness and perspectives that can selebar CRT.
Plasma gas also use phosphorus as well as on CRT technology, but the screen on the plasma gas can without the assistance perpendar light behind the screen. It will create energy that is not absorbed as much as CRT monitor. Contrast color produced is better than LCD.
For example, plasma television
