LED backlight LCD TV, good for the eyes?
Compared with liquid crystal is also reflected in the aspects of environmental protection compared with the traditional CRT, this is because the LCD has no high voltage components like CRT, so it may not appear as X ray high voltage lead to exceed the standard, so the radiation indicators generally lower than CRT.Although the LCD screen is much smaller than the average display, it is more likely to make our eyes tired and even cause headaches, because of the high brightness of the lcd. The researchers pointed out that when the brightness of the display reached 100cd per square meter (luminous intensity unit of La Kan), it would have an impact on the eyes. But they tested the liquid crystal display, its luminous intensity is more than 300cd per square meter, and some even reached 400cd - 500cd.
LED TV is TV LCD (Liquid Crystal Display), which is a kind of LCD TV, LCD TV and traditional is different is the use of the backlight is different, resulting in the performance of many different LED TV using light emitting diode as a backlight, CCFL backlight than traditional LCD TV in the thickness and picture quality life, energy saving and environmental protection, more advantages, LCD has become the development direction of TV industry recognized.
LED backlight LCD TV is not absolutely good for the eyes.LED backlight LCD TV damage to the eyes, relatively small compared to the old picture tube TV, LED TV radiation is relatively small, can reduce the damage to the eye.
