Computer MonitorsBy: Jason Fenwick

Basic Information about Computer Monitors

Monitor, Screen or Visual Display Unit are some of the names

The monitor is usually a Thin film transistor liquid crystal display (The TFT-LCD)

Originally computer monitors were used to process data while television receivers were used for entertainment

This making computer monitors have less graphics than a tv

Monitors have now been more processed to be used for both data and entertainment

Difference in Computer Monitors

The early computer monitors were used for processing data which allowed them to be made with less graphics than the newer models

Newer models are trying to become more hands on with better graphics to allow users to have more experience and entertainment on the computers

Different Ways of Screen Lighting

Cathode Ray Tube: These were the first monitors. They were used until 1980s and were knows and "Video display terminals”

Liquid Crystal: These type of screens are still with us and have been used, upgraded and continuously expanding known as LCD screens.

Organic Light-Emitting Diode: These screens are very expensive and new. They start pricing at around $7500 but are expected to drop in price

Video Card

The screen or monitor can display video and information generated through the "Video card”

The video card is placed inside the computer, which allows screen or monitor to be viewed.

The video card is a rectangular shape with tons of contacts on the bottom of the card and one or more on the side for connection to other devices

What is the LED?

An LED is a Semiconductor that permits current flow in one of the directions. this allows heat to be created which also gives off light

The Sixth Sense.

Computer Monitors are going to start to become more and more interactive with people therefore creating the sixth sense.

The sixth sense is going to be a digital world that can be accessed using your hands

Using the sixth sense people will be able to control computers with their hands and the computer screen with out having a real screen.

This will further advance the monitor because it will allow any surface to become your monitor
