Answer 1

The display component of a television set is referred to as a Cathode Ray Tube (CRT). This vacuum tube incorporates an electron gun and a luminescent display surface. The electron gun generates a focused electron beam that impinges on the phosphor-coated screen, thereby producing images.
This technology was prevalent in older televisions and computer displays prior to the widespread adoption of LCD and LED screens.
