Light sensors, such as sensors for ambient light, manage the backlight of the display on a phone. Ninety percent of smartphones have it, according to Bouchaud, who also mentioned that color sensors can come with RGB (red, green, and blue), which is actually supposed to improve the display. It adapts to the kind of light the user has on the phone. Sunlight, neon light, and incandescent light are all different environmental lighting situations that are supported now on these devices. Light sensors are also used for high-resolution displays.

AMS' digital ambient light sensor
The ams AG'sTSL4531 is a digital ambient light sensor that is targeted at daylight harvesting. The device is in automatic control of street lights and security, billboards, and automotive lighting. It can also be used in solid-state lighting (SSL) and general lighting for automatic control and daylight harvesting to maximize energy conservation. It approximates regular human eye responses under different lighting conditions. It comes with a wide dynamic range of ALS, which makes it especially practical for outdoor applications in which it is directly exposed to sunlight. It allows for display backlight control for extended battery life and optimal visibility in cell phones, tablets, and notebooks. It is integrated with LEDs to offer an additional 30% energy savings. It also offers three user-selectable integration times of 400 ms, 200 ms, and 100 Ms. It rejects 50 Hz to 60 Hz of lighting ripple and comes in ultra-small 2 mm x 2 mm Chip LED package. It comes with 2.5 V supply voltage with 1.8 V logic interface.
