In fact, LED display screen is still LCD display screen in essence, but LCD TV with LED backlight is adopted, and the LCD display screen in everyone's mouth is the traditional LCD display screen, which adopts CCFL backlight. The display principle is similar. Here, I call these two types of backlight LCD collectively as LCD display.

The pixels of the LCD display cannot be self luminous, while the pixels of the OLED screen can be self luminous. This is the biggest difference between the two screens. At present, Samsung's AMOLED screen is actually a type of OLED screen. AMOLED can achieve static screen display, which is due to the self luminous characteristics of OLED screen pixels.

Because the LCD screen will not emit light by itself, the LCD screen adopts a blue LED backlight, which is covered with red filter, green filter and colorless filter. When the blue light passes through the three filters, it forms RGB three primary colors. However, the blue light cannot be completely absorbed by the filter, and will penetrate the screen to form short wave blue light. When human eyes are in close contact for a long time, it will cause damage.

Which is more eye damaging than LCD, led and OLED screens?

No matter what kind of screen, it will cause damage to your eyesight. We should try to avoid looking at the mobile phone screen for a long time and reduce the use time of the mobile phone in a dark environment.

If you really want to choose one of them who hurts your eyes more, I choose OLED screen. Unfortunately, AMOLED screens will be used in high-end mobile phones from apple, Samsung and many domestic manufacturers.
