Abstract:
A backlight control method is provided. The method includes: determining, based on a global backlight brightness value, a backlight brightness interval in which the global backlight brightness value is located; determining, according to a correspondence between the backlight brightness interval and a backlight gain coefficient table, a backlight gain coefficient table corresponding to the backlight brightness interval, where the backlight gain coefficient table is configured to indicate a gain coefficient corresponding to a partition backlight brightness value; determining, according to a partition backlight brightness value of each of backlight partitions and the backlight gain coefficient table, a gain coefficient of each of the backlight partitions; and driving each of the backlight partitions according to the gain coefficient of each of the backlight partition and the partition backlight brightness value of each of the backlight partitions.
