First Claim
Patent Images
1. A method for adjusting brightness of a display screen executable by at least one processor of a computing device, the method comprising:
- obtaining vision information of a user;
determining a nearest distance, a longest distance, and an optimal distance between the user and the display screen;
detecting an actual distance between the user and the display screen;
comparing the actual distance to the nearest distance, the longest distance, and the optimal distance;
calculating a brightness value of the display screen according to the comparison result; and
adjusting brightness of the display screen according to the calculated brightness value.

Abstract
In a display screen brightness adjustment method, vision information of a user is obtained. A nearest distance, a longest distance, and an optimal distance between the user and the display screen are determined. An actual distance between the user and the display screen is detected. The actual distance is compared to the nearest distance, the longest distance, and the optimal distance. Then a brightness value of the display screen is calculated. Accordingly, brightness of the display screen is adjusted.
