Is LCD production harmful to human body? If so, what are the injuries?

according to statistics.
due to long-time use of computer, 57% of graphic design and program developers in the world have poor eyesight, which is mainly due to the damage caused by display radiation.

according to statistics.
due to long-time use of computer, 57% of graphic design and program developers in the world have poor eyesight, This is mainly due to the damage caused by the display radiation.
from the current market situation.
flat panel display has gradually replaced the traditional CRT display, but compared with low radiation liquid crystal display, the electromagnetic radiation of flat panel display is still very high, which will cause certain impact on human health.
especially for pregnant women, children and children For the elderly and the young people in their growth and development period,
long time use of this kind of display will cause immeasurable harm to the body.
in addition,
due to the "scanning" display mode that CRT can not overcome, Using CRT display for a long time will also bring great damage to users' vision.

another problem of using CRT technology is that high energy electron beam will produce some harmful rays when bombarding phosphors.
although some measures can be taken to reduce its damage to human body, However, it can not completely eliminate all the potential hazards.
LCD is different from CRT.
it uses a cold light source similar to fluorescent tubes to produce bright backlight. After passing through the color filter and liquid crystal pixel unit, it presents the color we need and will not produce harmful rays.
LCD has a simple structure.
it is small in size and has little waste after scrapping, It is easy to recycle.
moreover, the heavy metal elements which are difficult to recycle are much less than CRT.
the results show that CRT is more suitable for recyclingThis makes LCD more environmentally friendly.

LCD is not zero radiation.
.
however.
is LCD really "zero damage" to our eyes? In terms of radiation damage alone, it is true that LCD screen does not have as strong radiation damage as CRT screen, but it can only be said to be "low radiation" rather than "zero radiation". "
moreover,
some inferior brands of LCD will produce strong electromagnetic waves.
the research report points out that long-term exposure to electromagnetic waves will cause some symptoms of nerves and allergies to users, The symptoms include headache, vomiting, arrhythmia, memory loss, infertility, stroke and so on.
it may even cause digestive system disorders, neurological disorders and fertility reduction and other serious consequences.

.
at present.
most LCD manufacturers in the market pay too much attention to its multimedia function, memory loss, infertility and stroke The digital signal receiving function and fashionable appearance often ignore the health concept as the foundation of LCD.
due to too many additional functions,
the power consumption and operation power of the display are increased, and the electromagnetic wave emission and resource consumption are increased to a certain extent, which makes our original intention of choosing LCD for environmental protection and health backfire.
