[Summary description] In China, parents have always opposed their children's indulging in video games. One important point is that it hurts the eyes. Moreover, with the increase in the number of video games, the number of Chinese people suffering from myopia and eye diseases is also increasing. Is it possible to conclude that TFT screens hurt the eyes? The answer is no! Today, I will discuss with you that this TFT screen does not hurt your eyes. Below, we will discuss around this issue.
1. Without comparison, there is no harm.
Everyone asks if the tft screen can hurt the eyes? The answer is yes, all screens are harmful to the eyes when used for a long time, because looking at the object of concern for a long time can cause irritation to the eyes, thereby reducing vision.
But the tft screen actually hurts the eyes no higher than other types of screens. As long as it is used properly, the tft screen is not harmful to the eyes. The tft screen adopts DC dimming technology, which is considered by the industry to be the least harmful to the eyes, while the dimming technology used in the tft screen is DC dimming technology. For example, OLED adopts PWM dimming technology. The principle of PWM dimming is to adjust the on-off speed of OLED by adjusting the on-off speed of the OLED screen. The faster the on-off speed, the higher the brightness of the OLED.
2. DC dimming.
In general, the tft screen adopts DC dimming. The principle of DC dimming is very simple, that is, the brightness of the tft screen is changed by increasing or decreasing the circuit power of the tft screen. Power = voltage x current, so changing the voltage or current can change the screen brightness tft.
In short, the tft screen does not hurt the eyes, it is certain that it hurts the eyes, but it depends on how to use it. Using the tft screen correctly has a much lower lethality than other types of screens. This is why the industry says that on the tft screen Does not hurt the eyes.
