ELECTRONIC APPARATUS AND DISPLAY BACKLIGHT CONTROL METHOD

摘要

An electronic apparatus and a display backlight control method are provided. The electronic apparatus includes a display, a processing unit, a read-only memory and a backlight controller. The read-only memory stores a basic input output system (BIOS) and a setting table. The setting table includes a plurality of backlight setting values corresponding to each of the displays. When the processing unit executes the BIOS, the processing unit identifies an identifier corresponding to the display connected to the electronic apparatus, so as to obtain the backlight setting values corresponding to the display according to the identifier and the setting table. Then the processing unit provides the backlight setting values to the backlight controller, and the backlight controller controls the backlight power of the display according to the backlight setting values.
