Is TFT screen harmful to the eyes?

Many people feel that playing electronic products, will hurt the eyes, and indeed, with the increase of electronic products, people suffer from myopia, as well as eye diseases more and more, then there are people who will ask, TFT screen whether it hurts the eyes? Next we will discuss around this issue.

1. No comparison, no harm

Do people say that tft screens hurt their eyes?

The answer is yes, all screens hurt the eyes when used for a long time, because staring at the item for a long time will cause irritation to the eyes, thus reducing the eyesight.

However, tft screens are not as harmful to the eyes as other types of displays, and as long as they are used appropriately, they will not cause any harm to the eyes. This is mainly with the tft screen dimming method, tft screen using the dimming method is DC dimming, this dimming method is the display industry is recognised as the least harmful to the eyes of the dimming method. And for example, OLED is using PWM dimming, the principle of PWM dimming is to let the OLED screen by adjusting the speed of brightness to adjust the OLED brightness, the faster the speed of brightness, the higher the OLED brightness.

2. DC dimming

TFT screens generally use DC dimming, and the principle of DC dimming is very simple, which is to change the brightness of the TFT screen by increasing or decreasing the power of the TFT screen circuit. Power = voltage x current, so changing the voltage or current can change the brightness of the TFT screen.

In conclusion, does TFT screen hurt eyes? It is certain that it hurts eyes, but it depends on how it is used. Proper use can avoid damage. The lethality of TFT screen to eyes is much lower than that of other types of displays. This is why the industry says that TFT screens do not hurt eyes.
