Character LCD Modules TV Really radiation?

In theory, the traditional CRT TV display material is phosphor by electron beam strikes the phosphor display, the electron beam hit a moment on the phosphor will have a strong electromagnetic radiation, although there are many CRT TV products the radiation more effective treatment, as much as possible the amount of radiation to a minimum, but it is difficult to completely eliminate. Relatively speaking, LCD TV has its own unique advantages in terms of prevention of electromagnetic waves the strict sealing technology will be a small amount of electromagnetic waves from the driver circuit is enclosed in the display, theoretically there is no radiation. While the ordinary display to the need to dissipate heat must be placed as to let the internal circuit in contact with air, so that the internal circuit to generate an electromagnetic wave is also a large number of outwardly "leak".color lcd display module

Most authoritative radiation evaluation report to implement a five-point scale, who was named one-fifth, are all seriously overweight, need to pay attention; belong exceeded more than three weeks, you need to pay attention to; Star, is safe, you can rest assured that use. The electromagnetic radiation at two levels, which the band at work in μT, if the radiation is strong radiation more than 0.4μT in a certain harm to the human body, long-term exposure to susceptibility to leukemia. If radiation in the following 0.4μT, relatively safe. Radiofrequency unit is μW / cm 2. Radiation evaluation report shows that the LCD TV, both positive and half a meter or three meters in front of the range, instant boot normal viewing, change the channel, the the standby test results are 0.1μT the side only 0.11μT, basically The radiation intensity does not change. Series of radiation tests on traditional TV, LCD TV, plasma TV, rear projection TV, LCD TV, rear projection TV radiation minimum, slightly stronger than that of plasma TVs, traditional CRT TV CRT maximum radiation.Character LCD Display

The above data is not LCD TV is absolutely no radiation, people can rest assured that the purchase and watch. But in fact, some common sense will know: by electricity from the conductor will produce a magnetic field. Therefore, the single radiation damage, really did not like the CRT screen LCD TV so strong radiation damage. Its radiation than cathode ray tube itself to be small, but that no radiation is completely impossible, it is, after all, is an electronic device itself in addition to the liquid crystal panel itself, there are many internal circuit device. It can at best be said to be "low-E" instead of "zero radiation. The principle of the radiation current generates a magnetic field, the magnetic field generates an electric field, electric field and then generate a magnetic field of such an infinite loop. LCD TV screen TV screen than the commonly used to count, so by the total area of ​​the LCD TV radiation, radiation or inevitably.
