Simply put, the night mode technology reduces the minimum brightness of the screen to a lower level through more precise and detailed adjustment of the screen backlight to ensure a more comfortable viewing effect at night.
First of all, we need to understand the structure of the display screen. The main components of the display screen are the LCD panel and the LED backlight assembly. There are two ways to reduce the brightness of the display screen: one is to reduce the light transmission rate of the LCD panel, and the other is to reduce the brightness of the display. The brightness of the background light.
The night mode technology used by Xiaomi phones (REDMI phones) is to further reduce the minimum brightness that the screen can display by optimizing these two aspects.

cd/㎡ is the unit of brightness, candela per square meter (cd/㎡); it refers to the light intensity density of its unit surface in a certain direction, which can also be said to be the brightness of the light source or the illuminated surface perceived by the human eye.
