Abstract:
An electronic device having a display unit, an indicator, an illuminance sensor and a controller is provided. The indicator is configured to be turned on for emitting light and to be turned off. The illuminance sensor is configured to sense ambient illuminance. The controller is connected to the display unit, the indicator and the illuminance sensor. The controller is configured to turn on and off the indicator. The controller is configured to set brightness of the display unit depending on a value of the ambient illuminance sensed by the illuminance sensor while the indicator continues to be off.
