Explanation:
Detailed explanation-1: -Cathode-ray tube The first computer monitors used cathode-ray tubes (CRTs).
Detailed explanation-2: -The earliest version of the CRT was known as the “Braun tube", invented by the German physicist Ferdinand Braun in 1897. It was a cold-cathode diode, a modification of the Crookes tube with a phosphor-coated screen. Braun was the first to conceive the use of a CRT as a display device.
Detailed explanation-3: -Electrons that pass through the mesh then hit the phosphor coating which is on the inside of the glass screen. When the particles hit the phosphor, they immediately light up-causing the light to shine through the front of the monitor, thus making up the picture on the screen.
