Light sensor is integrated by Apple on their Macbook product lines. So what is the use of the light sensor? Let’s go with Tnhelearning.edu.vn to learn about it today!
What is Ambient Light Sensor?
Ambient Light Sensor aka light sensor . Designed next to the camera cluster on the front of technology devices in general and Macbook in particular. Ambient Light Sensor is a type of optical sensor. With the function of adjusting the screen light intensity appropriately in different environments, to enhance the user experience.
Working principle of light sensor
Optical diodes adapt to different spectrums. From there, based on the principle of “absolute position” to help perceive light and adjust the light intensity of the screen. After sensing the change of ambient light, these diodes will transmit a signal to the processor so that the screen automatically increases and decreases the brightness to suit the best.
Advantages and disadvantages of Light Sensor
Advantage
- Light sensor helps to reduce the case of harmful light to the eyes. The screen will automatically adjust the brightness to match the surrounding environment.
- Improve the display quality of devices to users with the best experience.
- Adjusting the screen brightness will help the laptop not drain the battery too much during use.
Defect
The unusual increase or decrease in brightness will sometimes cause discomfort to users. Especially when you are in an area where the light changes with each angle, this will cause the screen light to be continuously increased and decreased.
How to enable/disable Light Sensor on Macbook
Go to Settings > Select Display > Tick Automatically adjust brightness.
So you have enabled the automatic light adjustment function on the Macbook. When you don’t want to use it anymore, just remove the check mark in that box.
