Method comprise the steps：
The current environment temperature of step S1, acquisition terminal.Terminal can be by built-in or external temperature sensor to environment
Temperature is detected.
Step S2, the first threshold temperature by terminal current environment temperature with setting are compared, and judge that terminal is current
Environment temperature whether be more than the first threshold temperature, when the current environment temperature of terminal is more than the first threshold temperature, into step
Rapid S3, is otherwise failure to actuate.
Step S3, turn down screen intensity.The screen intensity of terminal can be adjusted by preset rules, it is as current in calculated
Difference between environment temperature and the first temperature threshold, then according to the difference and default algorithm, calculates the screen after turning down
Brightness value, then adjusts the screen intensity of terminal according to calculated screen brightness value.Assume that default algorithm is that temperature is every
2 DEG C are raised, screen intensity just turns down 1cd；The first temperature threshold is assumed for 25 DEG C, detecting the current environment temperature of terminal is
39 DEG C, both differences are 4 DEG C, then screen intensity turns down 2cd.When the Amplitude Ratio that screen intensity is turned down is larger, can be set to by
Default paces are adjusted to screen intensity, in case human eye cannot be adapted at short notice.
