Is the liquid crystal display safe to the human body?

The liquid crystal display does not have no radiation absolutly , just radiation is low, it is difficult to perceive . Liquid crystal display and purely flat biggest difference lie in the electronic screen is different from picture tube, so the difference that the radiation degree caused stood opposite each other. The liquid crystal display has certain radiation, just radiation is little. Not having no radiation absolutly, the injury and influence to a certain extent exist to eyes.

The liquid crystal display has less and more injury to the human body than the past RTC display, but does not mean that the liquid crystal display has no injury to the human body. RTC display with getting long to can make eyes redness turn sour, but to liquid crystal display, what above-mentioned situation show very obvious, it is difficult for eyes not to produce the tired sense , but this does not mean that the liquid crystal display has no effect on eyes.

Liquid crystal display, will feel very tired if the screen is long that look at eyes. Ordinary to is it can feel tired one hour to see while being purely flat, and liquid crystal display think will feel tired in 3 hours. 30% of the persons feel tired after using 3- hours of liquid crystal display, 33% of the persons feel after using 5- hours, 8% of the persons are using 6-  Did not feel tired 7 hours later. It is tired that 25% of the persons have no sense . Through the careful contrast, we find that it is comparatively lower than the tired sense degree after using the purely flat display to use the tired sense of the liquid crystal display.

But liquid crystal display true eyes in we accomplish " zero injury "?

Though only as regards radiation injury, certain liquid crystal display screen have strong radiation injury as CRT screen, but it can only it says to be " low radiation " but not " zero radiation " reluctantly. And some quality inferior of inferior brand liquid crystal display will produce the strong electromagnetic wave. The research paper points out , it will cause nerve and some irritated symptoms to the user in the electromagnetic wave environment to expose for a long time, called it " the electromagnetic wave allergy ". The symptom is as follows: Having a headache , vomitting , cardiac arrhythmia , memory failing , infertile , apoplexy ,etc., serious consequence of lacking proper care and reducing fecundity etc. that it will produce the digestive system disorder , nerve that even.

Harmful to radiation for what has been stopped and reduced the display, the design of the display should pass MPR II authentication , TCO authentication , and CCC authentication of our country, all there is measuring standard that radiation is correlated with in the authentication . So will not endanger the health through LCD display of authentication .
