What are video display devices?
Video display device means an electronic device with an output surface that displays or is capable of displaying moving graphical images or visual representations of images sequences or pictures that show a number of quickly changing images on a screen to create the illusion of motion.
What are the three video display types?
As a rule, specialists name three types based on what is inside them. These types are: CRT – Cathode Ray Tube. LCD – Liquid Crystal Display.
What do you mean by display devices?
A display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people). Common applications for electronic visual displays are television sets or computer monitors.
What are the properties of video display devices?

What are the use of display devices?
The display device is an output device used to represent the information in the form of images (visual form). Display systems are mostly called a video monitor or Video display unit (VDU). Display devices are designed to model, display, view, or display information.
What are the characteristics of display devices?
Display technology – CRT or LCD technologies.
Which type of display is best?
IPS LCD Stands for In Plane Switching liquid Crystal Display. This technology offers better display quality as compared to the TFT-LCD display. The good part about IPS LCD is that it offers better viewing angles and consumes less power. Due to higher costs, it is found only on high-end smartphones.
What characteristics should a display have?
