Short slide on types of moniter and display on market
and what is running and what is coming on market

2. INTRODUCTION A computer monitor is an output device that displays information in pictorial form. A monitor usually comprises the display device, circuitry, casing, and power supply . Monitors are very important because without them you wouldn't be able to view your output.

3. HISTORY Originally, Monitors were used for data processing while Television sets were used for entertainment . As technology developed engineers realized that the output of a CRT display was more flexible than a panel of light bulbs and eventually, by giving control of what was displayed in the program itself, the monitor itself became a powerful output device in its own right. Computer monitors were formerly known as visual display units ( VDU ), but this term had mostly fallen out of use by the 1990s.

4. TECHNOLOGY Cathode Ray Tube monitors The first computer monitors used were cathode ray tubes (CRTs) and these monitors employed the use of CRT technology. The display was monochrome and far less sharp and detailed than on a modern flat-panel monitor. This necessitated the use of relatively large text and severely limiting the amount of information that could be displayed at one time. Later on , high-resolution CRT displays were developed for the specialized military, industrial and scientific applications.

5. TECHNOLOGY Liquid crystal display The LCD monitor makes use of one of the most advanced tech available today by using CCFL(cold cathode fluorescent) for back lighting. The advantages of LCDs include their compact size which makes them lightweight. The images transmitted by LCDs do not get geometrically distorted and they do not consume much electricity and can be run off of batteries. They also have a larger viewing area , with a typical widescreen monitor having a 16:9 aspect ratio ,compared to 4:3 aspect ratio of a typical standard width monitor.

6. TECHNOLOGY Organic LED (light-emitting diode) monitors OLEDs are flat panel , or slightly curved displays which make use of light-emitting diodes for back lighting instead of CCFL used in LCDs for back-lighting. Organic light-emitting diode (OLED) monitors provide higher contrast and better viewing angles than LCDs . It has a very short depth and is light in terms of its weight. They are often less expensive , more reliable , longer lifespan and less environmental impact.

7. ADVANCEMENTS Some other types of Monitors:- Touch Screen Monitors - These use touch as an input method. Ultra wide Screen Monitors – Monitors that feature an aspect ratio of 21:9 as opposed to the more common 16:9.Mainly used for gaming purposes. Tablet Screens Monitors – This is a combination of monitor with a graphics tablet.
