What's the difference between buying a mobile phone's LCD screen or LED and eyes?

In fact, to be more accurate, the material of mobile phone screen can be divided into organic light-emitting diode and LCD screen, with different materials, different lighting principles, different use time and different cost control. Therefore, in order to see the influence of organic light-emitting diode screen and liquid crystal screen on human eyes, we need to start from many aspects. First of all, let's understand the difference between these two screens. Almost all the mobile phones we use use these two materials as screens, so we can find the difference between the two materials through the small problems in our daily use.

The LCD screen makes the screen shine through the backlight, so we can distinguish what screen the mobile phone uses by the screen color. Because the LCD itself does not emit light, it needs the backlight of the white liquid crystal layer to penetrate the black screen, but this liquid crystal layer cannot be completely extinguished, so the LCD we see is generally gray. On the other hand, every pixel of the screen of the organic light emitting diode is self-luminous. As long as it is turned on, the screen itself glows, and there is no need for an external light source.

The LCD screen will also leak light in the dark because of the backlight of the screen, which greatly affects the viewing experience of users' daily use and even irritates their eyes when playing mobile phones at night.

Speaking of organic light-emitting diode screens, although organic light-emitting diode screens have many advantages over LCD screens, there are also many places that affect people's viewing experience. Because the organic light-emitting diode screen itself emits light, on this basis, its screen brightness is more prominent and the contrast is higher, so it is easier to hurt people's eyes.

At the same time, the OLED screen will flicker under normal circumstances, which is almost the most criticized place of this screen. This kind of screen flash is not easy for us to see, so it hurts our eyes inadvertently.
