It stands for Cathode-ray tube. CRT monitor was first developed by German scientist Karl Braun in 1897 but it wasn’t until 1940’s when the first CRT came out in a TV. Even though it was developed over hundred years ago, scientists have improved its picture quality over time. But it still runs on the basic principal. It is used in most TV screens as well as PC monitor. How CRT tube works is pretty simple. It moves electro beams back and forth and displays it across the back of the TV or PC monitor. Some negative points of CRT monitors is that they are power hungry, they are heavy and pretty big. The big advantage of it is that it is cheaper to manufacture which enables the poor countries to afford such a product. In a competition world for TVs and computer monitor has changed over the years. Many large companies have halted their production of CRT monitor due to drastic decrease in revenue. Most companies have recorded a decrease of half of what CRT monitors used to bring. More companies are focusing on big demand of the new LCD monitors. It's a changing world and you have to change with it.
