Crt

Cathode Ray Tube (CRT) Technology has been around since the 1930's. it is reliable, tested, and effective. However, because of its' age, it is also not energy efficient, it is bulky, and the quality of to display is beginning to look more and more dated. because of this, CRT has recently been shunned in favor of LCD, Plasma, and LED technologies

How CRT WorksEdit

CRT displays work by firing electrons from an electron gun at high speeds toward a phosphorescent screen. When the hit the phosphor, they turn to photons, highly charged atomic particles. Color TV's use 3 different electron guns: one for red, one for green, and one for blue. Each of these can light multiple pixels, and it turns into a viewable image. The electron beams that hit the screen are all focused on a shadow mask, which seperates the pixels from one another. == CRT Positives/Negatives==
