Ambient light sensors are widely used in mobile devices such as mobile phones, tablet computers, and notebook computers. They are also used in the cars and TVs. When the indoor lights are dimmed, the pupils of the eyes will be enlarged. If the screen brightness of electronic products is too high, the users may feel uncomfortable.
The ambient light sensor can adjust the brightness of the screen to the brightness acceptable to the human eye, and it can also prolong the battery life. In broad daylight or a bright environment, the backlight needs to be brighter. However, long-term high-brightness display increases power consumption and greatly reduces battery life. The battery life is greatly extended due to the use of the ambient light sensors.
For the LED lighting, the ambient brightness is sensed by the ambient light sensor, and the brightness of the LED lamps is adjusted accordingly, which is not only environmentally friendly, but also saves the number of LEDs used whenever it is possible.
