A display apparatus including at least one sensor, a processing unit and a control unit is provided. The sensor senses a human body. The processing unit is coupled to the sensor, and captures and processes signals from the sensor to obtain a sensing data. The control unit is coupled to the processing unit, and analyzes and determines whether the human body is to enter into or to be distant from a sensing range of the sensor according to the sensing data. When the control unit determines that the human body is to be distant from the sensing range for a first predetermined time, the control unit turns off the display apparatus or makes the display apparatus get into a power-saving/sleeping mode. When the control unit determines that the human body is to enter into the sensing range for a second predetermined time, the control unit turns on the display apparatus. |
