Write the types of monitors? Explain their features.

The different types of monitors are:

1. Cathode Ray Tube (CRT) Monitors — The features of a CRT monitor are:

   1. CRT monitors consist of an electron gun.
   2. In these monitors, a beam of electrons lights up the pixels/phosphor dots, which form the inner coating of the screen.
   3. Colour is achieved by combining Red, Green, and Blue (RGB) shades of different intensities.
   4. CRT monitors are bulky and occupy a lot of space.
   5. They are available in various sizes, like 14 inches, 15 inches, 17 inches, and 21 inches.
   6. A CRT monitor still has better contrast ratios and viewing angles than any other type of computer monitor.

2. Liquid Crystal Display (LCD) Monitors — The features of LCD monitors are :

   1. LCD monitors are relatively thinner and lighter than CRT monitors.
   2. They use the light modulating properties of Liquid Crystals (LCs).
   3. Liquid Crystals do not emit light directly.
   4. They save a lot of space and can be mounted on walls.
   5. They provide a wide viewing angle and come in various sizes ranging from 17 inches to 60 inches.
   6. They display sharp images and require less power to run.
   7. They are used in a wide range of applications including computer monitors, television, instrumental panels, aircraft cockpit displays, etc.
   8. They are also used in devices, such as clocks, watches, calculators, gaming devices, and telephones.

3. Light Emitting Diode (LED) Monitor — LED display has the following features:

   1. LED monitors are light emitting diodes that act as performance boosters in them.
   2. LED monitors offer better colour quality, clarity, and display than the LCD monitors.
   3. These monitors are flat, thinner and lighter in weight.
   4. The biggest advantage of LED display is its efficient and low energy consumption, which is especially needed for handled and chargeable devices, such as mobile phones, tablets, and laptops.
   5. These monitors are in maximum use nowadays.
