What is a CRT Monitor?
CRT monitors have been the backbone of computer displays since home computers began popping up in the ’90s, but advances in technology are beginning to render the CRT monitor obsolete. However, CRT monitors are still preferred in a few applications. What Is a CRT Monitor? CRT stands for cathode ray tube. A CRT monitor is built using old vacuum-tube technology that formed the basis for many televisions and viewing screens for the past several decades. CRT technology involves electrons firing through a vacuum, translating to fast response times and a clear, precise picture. For years, CRT monitors were the only choice for home computer users. CRT Monitors Are Larger Because of the mechanics involved in CRT monitors, they’re larger than their LCD cousins. Even a flat panel CRT monitor tends to be quite bulky, requiring a lot of space from the back of the monitor to the front, whereas LCD monitors are flat and don’t require much space. If space is a consideration, LCD monitors are preferab
CRT stands for cathode ray tube, describing the technology inside an analog computer monitor or television set. A CRT monitor or TV is readily recognizable by its bulky form. LCD monitors and plasma television sets, or flat panel displays, use newer digital technologies. The CRT monitor creates a picture out of many rows or lines of tiny colored dots. These are technically not the same thing as pixels, but the terms are often used interchangeably. The more lines of dots per inch, the higher and clearer the resolution. Therefore 1024 x 768 resolution will be sharper than 800 x 600 resolution because the former uses more lines creating a denser, more detailed picture. Higher resolutions are important for displaying the subtle detail of graphics. For text, resolution isn’t as critical. But how do those colored dots appear on the screen? Inside a CRT monitor is a picture tube that narrows at the rear into a bottleneck. In the bottleneck is a negative charged filament or cathode enclosed in
A CRT Monitor is a computer monitor based around a device called a Cathode Ray Tube. The size and shape of the tube has determined the dimensions of computer monitors for many years, and has recently been upstaged by LCD monitors. Many people and companies are still using existing CRT monitors until they need to be replaced or upgraded.
The original CRT (cathode ray tube) technology was invented more than 100 years ago and has been greatly refined since. Inside a color CRT, three electron guns shoot streams of electrons at the screen. A mask blocks the electrons so that the beam from one gun hits only red phosphor dots on the screen, just as the beams from the other guns only hit green or blue phosphors. By controlling the position of the beams and how fast they turn on and off, a CRT can create pixels of varying sizes, so it can produce different-resolution images with little loss of image quality. Although they’re big and boxy, CRTs are inexpensive–and indispensable for some computing tasks such as video-editing and gaming. Here’s a look at the good and the bad in CRTs.
