How does a CRT monitor produce color?

Answer 1

we uses the crt monitors for displays the colors on the screen.the CRT monitors have a vacuum tube, which initialy filled with gases.the crt monitors have a electron gun, the electron gun consists a cathod,a anode and a focusing anode.initially we put a voltage on the anode which create a electric field between cathod and anode.when the electric field established the electrons are start moving from cathod to anode and this flow of electron is natural.the anode have a small hole between it and electrons are come with some velocity and have some mometum.Due to their momentum they cross the anod on the electron gun and strike on the crt screen called flouphorence.when the electrons are cross the anode through its hole then focusing anode on electron gun focus the electrons into a narrow beam.CRT also contain the two other plates known as vartical and horizontal plate.the horizontal plate make the horizontal adjustment of electron beam where as the vartical plates make vartical adjustment of electrons beam.

The crt screen are cover with phosphor and when electron beam strick on ctr screen's phosphor the phosphor of crt sreen get excited and they come energetic and then start emitting light so that they come into initial state.the time taken by phosphor to maitain the the light is called persistance.

the persistance is just like a resistance which resists the phosphor to release their energy come in to initial stage.there rae different type of phospor are use on the crt screen to produce color.majorly p1 p2 ......p7 p11 p12 p35 etc.

when the phosphor loses their energy become fade.to maitain the picture on the screen we needed such a mechanism to maintain the color of phosphor .we can maintain the phosphor color by refresing the light on the same point of posphor to maitain the color during certain period of time.this is called refrashed CRT.

Answer 2

The CRT uses an evacuated glass envelope which is large, deep (i.e. long from front screen face to rear end), fairly heavy, and relatively fragile. As a matter of safety, the face is typically made of thick lead glass so as to be highly shatter-resistant and to block most X-ray emissions, particularly if the CRT is used in a consumer product.

Answer 3

Uses its brain; there are many neuron links inside a processor, this allows the computer to perceive the three primary colours and from this, allows the computer to 'mix and match' as such to generate all the colours that we ourselves are akin to.

Hope this helps!!!!
