In 1947, the cathode-ray tube amusement device, the earliest known interactive electronic game as well as the first to incorporate a cathode-ray tube screen, was created. From 1949 to the early 1960s, there was a shift from circular CRTs to rectangular CRTs, although the first rectangular CRTs were made … See more A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical See more Body The body of a CRT is usually made up of three parts: A screen/faceplate/panel, a cone/funnel, and a … See more CRTs were produced in two major categories, picture tubes and display tubes. Picture tubes were used in TVs while display tubes were used in computer monitors. Display tubes had no overscan and were of higher resolution. Picture tube CRTs have … See more Ionizing radiation CRTs can emit a small amount of X-ray radiation; this is a result of the electron beam's … See more Discoveries Cathode rays were discovered by Julius Plücker and Johann Wilhelm Hittorf. Hittorf observed that some unknown rays were emitted from the cathode (negative electrode) which could cast shadows on the glowing wall of … See more • LCD advantages over CRT: Lower bulk, power consumption and heat generation, higher refresh rates (up to 360 Hz), higher contrast ratios • CRT advantages over LCD: Better color reproduction, no motion blur, multisyncing available in many monitors, no input lag See more Under some circumstances, the signal radiated from the electron guns, scanning circuitry, and associated wiring of a CRT can be captured remotely and used to reconstruct what is shown on the CRT using a process called Van Eck phreaking. Special See more WebCathode rays are so named because they are emitted by the negative electrode, or cathode, in a vacuum tube. To release electrons into the tube, they must first be detached from the atoms of the cathode. The early cold cathode vacuum tubes, called Crookes tubes, used a high electrical potential between the anode and the cathode to ionize the ...
