Types of Computer Displays
1. Cathode Ray Tube (CRT)
Initially, these were mainly used as displays but they were large and very heavy with high power consumption rates. Cathode Ray Tubes works by directing electron beams onto the back surface of a screen causing it to emit light.
2. Liquid Crystal Display (LCD)
This type of display is flat and thin. It functions through the blocking of light rather than creating it like other types do. There are two glass layers with liquid crystal material between them in an Liquid Crystal Display. The crystals rotate to either allow or block light that creates images on screens. They are popular because they are slim and consume less power compared to CRTs.
3. Light Emitting Diode (LED)
In LED displays, small lights referred to as LEDs are used as their lighting source instead of other backlights like those found in LCDs . This makes them thinner and lighter than any other kind of display device panel can be made thinner using this technology too which contributes towards improved color and brightness features OLED uses organic materials while QLED utilizes nanoparticles for producing different kinds of LED displays
What is a display ?
A screen is a display that shows images or words. It allows us to view data from computers, phones, televisions, and other devices. It is very significant to have displays because they enable us to interact with technology and perceive things we want to know. Most of the current devices would not be easy to operate without displays. Some common types of displays are computer monitors, TV screens, and smartphone screens. They make our lives easier by clearly showing us visuals.
