Abstract
A method of preventing a backlight module from overheating and a display device are provided. The method can prevent backlight partitions from having a long-time high-brightness operation and causing the backlight module to overheat by obtaining a driving current of each backlight partition in the backlight module, judging whether a brightness of each backlight partition in the backlight module exceeds a reference brightness, and adjusting the brightness of each backlight partition that exceeds the reference brightness to a target brightness.
