Re: What is CRT in computer graphics? CRT is a component of the color monitor that was in practice earlier. It has been widely replaced by LCD panels. CRT stands for Cathode Ray Tube, which is essentially a tube where a jet of ions is projected onto a screen with the help of electricity and magnets. The corresponding area reacts by lighting up a phosphor dot. |

quick question Shalom people... I'm really new to the internet stuff so i really hope i am not asking stupid questions ... I want to learn how to get freebies... I heard some people submit some details and receive like a free trip, or one of those fancy mp3 players... so if anybody could please help me, I'd appriciate it deerly. Thanks. |

Re: What is CRT in computer graphics? hii CRT in computer graphics CRT means cathode ray tube which is used in older version of computer monitor now a days in modern monitors a thin transistor liquid crystal display (TFT-LCD) is used. The CRT monitor displays images with colors that can be viewed comfortably from different angles.It is useful for displaying and working with graphics and photographs where color plays an important role.CRT monitors are available with curved or flat screens. good luck |

Re: What is CRT in computer graphics? Its hard to explain CRT without any diagram... but still I am trying. first take a look at the diagram here: CRT is Cathode Ray Tube. The operation of most of the video monitors are based on CRT technology. A CRT is similar to a big vacuum glass bottle. It contains 3 electron guns that squirt out focused beam of electrons.. deflection apparatus (magnetic or electrostatic) , which deflects these beams both up and down and sidewise,... and a phosphor coated screen upon which these beams impinge. the vacuum is necessary to let those electron beams travel across the tube without running into airmolecules that could absorb or scatter them.... The primary component in an electron gun is a cathode (negatively charged) encapsulated by a metal cylinder known as the "control grid". a heater inside the cathode causes the electrons to be heated up as current is passed.. these heated electrons are accelerated towards the CRT screen by a high positive voltage applied near the screen or by "accelerating anode". The cloud of electrons is forced to converge to a small spot as it touches the CRT screen by a "focusing coil" using an magnetic field. A pair of magnetic deflection coils mounted outside the CRT envelope deflects the concentrated electron beam to converge at different points on the screen in the process of scanning. When the electron beam converges on to a point on the phosphor coated face of the CRT screen, the phosphor dots absorb some of the kinetic energy from the electrons. This causes the electrons in the phosphor atoms to jump to higher energy orbits. After a short time these excited electrons drop back to their earlier stable state, releasing their extra energy as small quantum of light energy....as long as these excited electrons return back to their stable state phosphor continue to glow (phosphorescence) but gradually looses brightness. The brightness of the light emitted by phosphor depends on the intensity with which the electron beam (no. of electrons) strikes the phosphor. The intensity of the beam can be regulated by applying measured negative voltage at the control grid, which in turn will shut off the electron beam by repelling the electrons and stopping them from coming out of the gun and hitting the screen. |
