CRT displays are bulkier and larger than flat-panel displays. One of the reasons why CRT isn’t used for modern-day displays involves its size. So, why aren’t CRT displays still being produced? Today, most displays use a flat-panel technology, such as liquid-crystal display (LCD) or one of its variants. As manufacturers gradually transitioned to these new flat-panel display technologies, CRT displays began to fade.Ģ008 was a turning point for the industry, as it marked the first time that flat-panel displays outsold their CRT counterparts. Around the turn of the 21st century, alternative display technologies emerged, specifically flat-panel display technologies. You typically won’t find any newly manufactured displays featuring CRT technology. The vacuum tube allows the electron gun or guns to shoot the phosphor compounds from behind. This is because their electron gun or guns are placed in a vacuum tube. Electrons essentially excite the phosphor compounds, causing them to illuminate so that an image is produced.ĬRT displays are also known as picture tubes. To produce images, CRTs strike the phosphor compounds with electrons. They feature a layer of phosphor compounds, which serves as the pixel layer. What Is CRT Display?Ī CRT display is a type of display device that uses one or more electron beams to produce images. To learn more about CRT displays and why they are no longer around, keep reading. Like many other display technologies, though, CRT has since become a thing of the past. CRT, in fact, has become synonymous with old-style displays. In the past, most displays - televisions, computer monitors, etc.

It wasn’t long ago when cathode-ray tube (CRT) dominated the display market.
