Why is the screen clearer than the LCD screen?

Different from LCD screen, TV screen is a display element developed from vacuum tube, which emits light through the impact of electrons on phosphor on anode. It is a self-luminous display element. It belongs to self-luminous pixels, so compared with other display pixels, it has a wider field of view and a more vivid display effect.

However, its disadvantage is that the radiation is large, and the electron beam will produce powerful electromagnetic radiation when it hits the phosphor. Relatively speaking, LCD has inherent advantages in radiation protection.
