Will the segment LCD screens we use radiate? Is it harmful to the human body?
Relatively speaking, liquid crystal displays have inherent advantages in radiation protection, because the harm to the human body is minimal. In terms of preventing electromagnetic waves, liquid crystal displays also have their unique advantages. It uses strict sealing technology.
The low electromagnetic wave of the self-driving circuit is encapsulated in the display. In order to dissipate heat, the internal circuit of the ordinary display must be in contact with the air as much as possible, so that the electromagnetic wave generated by the internal circuit will "leak" to the outside.
The display material of the traditional display is phosphor, which is displayed by hitting the phosphor with an electron beam. When the electron beam hits the phosphor, strong electromagnetic radiation is generated.
Although there are many display products that deal with the radiation problem effectively and reduce the amount of radiation as much as possible, it is difficult to completely eliminate it.
CRT is a cathode ray tube display with radiation, LCD is a liquid crystal display, without electromagnetic radiation, and the main box has no radiation.
Therefore, the LCD screen does not emit light, so you can rest assured.
