The invention discloses an LED over temperature protection method, terminal and computer readable storage medium. As for a terminal adopting an LED as a backlight source, when data of a to-be-displayed image is received and current of each LED backlight section is a preset maximal current, whether a current duty ratio of at least one LED backlight section higher than a preset current duty ratio isin presence or not is determined. If the current duty ratio of at least one LED backlight section higher than a preset current duty ratio is in presence, the accumulated lasting time length when thecurrent duty ratio of at least one LED backlight section is higher than a preset current duty ratio is determined. If the accumulated lasting time length reaches a preset threshold value, the currentof the corresponding LED backlight section is decreased to safety current and then kept for a while. Therefore, the temperature of the corresponding LED backlight section can be reduced quickly and damage due to over high temperature of the LED can be prevented.
