First, CRT (cathode ray tube) technology was implemented in computer monitors in 1992, but the commercial version was introduced only in 1954. This technique is being used since 2000 till date.

CRTs use a vacuum tube that is coated on one side with phosphorus. They emit light when all the electrons are spread over them. These types of CRTs produced output only in text form and were also colorless.

It was eventually changed to LCD (liquid-crystal display) technology. The LCDs we use today are divided into two parts namely TN (Twisted Nematic) and IPS (In-Plane Switching). IPS models are more expensive than TN display models, but those models are more capable of producing great colors, viewing angles, and a lightweight screen.
