For example, the intensity values of the two ambient light sensors are 70 and 80. The average value of the intensity values of the two ambient light sensors is 75. The electronic device determines the ambient light intensity according to the average value 75. For example, the ambient light intensity is determined as the average value 75. The electronic device controls the display screen to respond according to the average value, for example, reducing brightness of the display screen.

In some embodiments, the number of the ambient light sensors included in the electronic device may be three, four or other number. The plurality of ambient light sensor included in the electronic device are spaced apart from each other.

In some embodiments, as illustrated in FIG. 7, the display region 21 of the display screen 20 includes a first part 211 and a second part 212 disposed oppositely. It should be understood that, the first part 211 may locate at the top of the display screen 20, and a second part 212 may locate at the bottom of the display screen 20. One of the two ambient light sensors included in the electronic device may be disposed facing an edge of the first part 211, and the other one may be disposed facing an edge of the second part 212. For example, one of the two ambient light sensors included in the electronic device may be disposed facing the top left corner, and the other one may be disposed facing the lower right corner of the display region 21.

In some embodiments, as illustrated in FIG. 4, controlling the display screen to respond according to the ambient light intensity value at block S130 may include actions illustrated in following blocks.
