A CRT (Cathode Ray Tube) is, essentially, a big glass bottle which has had all the air removed. The front is then coated with a "phosphor" material which glows when struck by fast-moving electrons. In a colour screen, there's actually three phosphors - one which glows red, one which glows green, and one blue (hence: RGB, or Red Green Blue). Immediately behind the phosphor coating, there's a grid - like a fine mesh - to ensure the electrons only hit specific parts of the screen (the pixels) and don't just splash around the place. Finally, at the back (neck) of the "tube", there's an electron "gun" (three, for colour screens - one for each colour), which "fires" electrons towards the screen. Powerful electromagnets steer each beam towards the correct phosphor dots. The image on the screen is built up line by line; so each colour beam starts at the top left corner, and "scans" across, firing whenever a coloured dot is required. When the end of the line is reached, the beam jumps back to the left hand side, of the second line down; the process is repeated until all of the "scan lines" are complete; then the whole process starts again. And that, basically, is how a CRT works.
LCD monitors are NOT faster than CRT's, CRT images move at the speed of light and have almost no input lag. LCDs have input lag and this is why good ones are so expensive.
Yes they are the same. A cathode ray tube (CRT) uses an electron gun to "shoot" electrons from the cathode to specific positions on the anode of the CRT.
The CRT refers to cathode ray tube. This is the oldest of the varous TV types. More recent developments have been projection, plasma, etc.

No they do not.
CRT screens don't have a port for you to plug in a HDMI cable.
To type on and do your work just normal everyday things.
CRT screens can work with an input signal with varying refresh rates while TFT displays have a manufacturer-set refresh rate. TFT screens however produce clearer images than CRT.
CRT monitors use a beam of electrons to form the picture - LCD's use microscopic pixels. CRT's need large amounts of electricity to form the picture - LCD's work with low voltages.
there are not many similaritys between crt tvs and flat screen tvs the closed to a crt tv to flat screen technology is plasma tvs plasma tvs work in a similar way by having an electron hit a phosphorous screen which excites and produces light crt tvs work in a similar way
CRT Lanaudière was created in 2002.
CRT is cheaper than LED.
yes ..
i think dear it's by..refresh rate of crt..the screen refresh by vertical direction..so light pen can update it's possition..in every..refresh of crt'..but in lcd this is oppisite
