![]() They also produced an image faster with less input delay. They did not have a native resolution, allowing you to switch between resolutions without any loss of image quality. CRT monitors were able to reproduce colors more accurately than early LCDs. It is in fact the dominant electronic display device, and likely to remain so in the forseeable future. Robbins Contrary to the impression created by many proponents of flat panel displays, the CRT is not the last vestige of a moribund technology. A ViewSonic CRT monitorÄespite being completely replaced in the market by flat-panel LCDs, CRT monitors had some advantages over LCDs during the time they were both available. The cathode-ray tube will not go away m why it by D. Eugen Goldstein coins the term 'cathode rays' to describe the light emitted when an electric current was forced through a vacuum tube. The length required for the vacuum tube to operate meant that most CRT monitors were deeper than they were wide or tall, and the shape of the tube meant that they were very front-heavy. Boston civil servant George Carey was thinking about complete television systems and in 1877 he put forward drawings for what he called a selenium camera that would allow people to see by electricity. A 17" CRT monitor was one of the most common sizes and usually weighed around 35 or 40 lbs (15-18 kg). The vacuum tube used in a CRT monitor required thick, lead-coated glass to hold up to the pressure larger monitors required thicker glass, making them even heavier. Physically, CRT monitors were bulky and heavy compared to modern LCDs. The cathode-ray tubeA review of current technology and future trends. These phosphor dots - arranged in stripes of red, green, and blue ( RGB) - glow when hit by an electron to produce an image. A CRT display operates by firing electrons from the back of the vacuum tube towards an array of phosphor dots that coat the inside of the glass screen. CRT displays were a type of analog computer monitors and televisions commonly used up through the mid-2000s.
