1. Vehicle power supply limitation: Compared with household power supply, the voltage and stability of vehicle power supply may be limited. This will affect the brightness level of the display screen and limit the adjustment range.
2. Limitations of display design: The display design of some models may not be flexible enough, and the range of brightness levels may be narrow. This is due to the limitations of vehicle manufacturers on the layout and design of on-board equipment, which may lead to the limitations of the brightness level function of the display screen.
3. Automatic brightness level function of display screen: Some vehicles are equipped with automatic brightness level function, which can automatically adjust the brightness of display screen according to the change of ambient light. In this case, the user may feel that it is impossible to manually adjust the brightness because the display will automatically adapt to the ambient light.
It should be noted that different models may have different display brightness level modes and limitations. Some vehicles may provide a wider range of brightness levels and options, while others may limit the function and range of brightness levels.

In addition to the limitation of brightness level, the brightness of the display screen will also be affected by other factors, such as the lighting conditions of the use environment. In strong sunlight, even if the display screen is turned to the maximum brightness, its visibility is still limited. At this time, you can consider using a sun visor or adjusting the position of the vehicle to improve the visibility of the display screen.
In addition, the brightness of the display screen is also very important for the driver's visual experience and safety. Too bright or too dark display may adversely affect the driver's attention and visual fatigue. Therefore, it is suggested to adjust the brightness of the display screen according to the actual needs and environmental conditions to ensure a comfortable driving experience and safety.
