A device and a method for adjusting backlight brightness employed in a display are provided. The electronic device includes a display unit, a backlight unit, a light sensor, a distance sensor, and a control unit. The backlight unit is configured to emit backlight for the display unit. The light sensor is configured to sense ambient brightness of the electronic device in real time. The distance sensor is configured to sense an object within a predetermined coverage area in real time. The control unit is configured to detect whether the ambient brightness changes, evaluate whether the object is sensed by the distance sensor within the predetermined coverage area when detecting that the ambient brightness is low, and not control the backlight unit to adjust the backlight brightness of the display unit when the object is sensed within the predetermined coverage area.
