What is the basic colour's in CRTs?
Answer:
Red,Green & Blue
CRTs are also referred to as RGB (red, green, blue) monitors.
Red Green and Blue Its basic and primary colours, in the CRT(Cathod Ray Tube), Red Green and Blue Phosphor generate colour by help of electron beam . Percentage of electron beam intensity, this three Primary colours makes millions of colours .
As all the other post have said.. Red Green and Blue, but just to give you and many others something to think about is the fact that only colour info for red and blue are transmitted !Cheers Pete
The cathode ray tube (CRT), invented by German physicist Karl Ferdinand Braun in 1897, is an evacuated glass envelope containing an electron gun (a source of electrons) and a fluorescent screen, usually with internal or external means to accelerate and deflect the electrons. When electrons strike the fluorescent screen, light is emitted.
The electron beam is deflected and modulated in a way which causes it to display an image on the screen. The image may represent electrical waveforms (oscilloscope), pictures (television, computer monitor), echoes of aircraft detected by radar, etc.
The single electron beam can be processed in such a way as to display moving pictures in natural colors.
The generation of an image on a CRT by deflecting an electron beam requires the use of an evacuated glass envelope which is large, deep, heavy, and relatively fragile. The development of imaging technologies without these disadvantages has caused CRTs to be largely displaced by flat plasma screens, liquid crystal displays, DLP, OLED displays, and other technologies.
The inverse process can be used to create an electronic version of an image impinging on a suitable screen in the video camera tube: electrons are emitted by the photoelectric effect; the resulting electrical current can be processed to convey the information, later to be recreated on a CRT or other display.
