摘要： A digital photo frame (DPF) capable of indicating battery is provided. The DPF includes a light-emitting diode (LED) unit, a battery, a battery detection unit, a processing unit, and a display control unit. The battery detection unit is connected to the battery and is configured to detect the charge of the battery and output a low battery alarm signal when the charge of the battery is below a predetermined value. The processing unit is connected to the battery detection unit, and is configured to producing a control signal when receiving the low battery alarm signal. The display control unit is connected to the processing unit and the LED unit, and is configured to control the LED unit to change its display state when receiving the control signal.
