WebThe meaning of PHOSPHOR is a phosphorescent substance. WebBlack, White, and Gray: Nothing, All, or Some. When no electrons strike the phosphors of a computer screen the phosphors emit no light and the screen appears black. On a white section of a screen all three phosphors are excited and produce light with about the same relative intensities as in sunlight so the light appears white. WebPhosphors are materials that have the ability to absorb the high energy (short wavelength) emitted by the LED chip and down-convert them into lower energy (longer wavelength). … tsc1 and tsc2 mutation
