Abstract

The invention relates to an energy saving control method for a digital photo frame and a digital photo frame adopting the method. The digital photo frame is provided with a screen. The method comprises the steps that: a sensor used for sensing people at certain range around the digital photo frame is provided; the sensor shifts the digital photo frame into a power saving mode when the sensor does not detect any person appearing at the certain range after a certain period of time. The method of the invention shifts the system to an awakening state or causes the system to return to a normal working state in a real-time manner through the sensor which can still monitor whether any people are around the digital photo frame regardless of which status the sensor is at. The method monitors whether people appear around the digital photo frame through the sensor and coordinately adopts the stage energy saving control strategy, thereby being capable of greatly reducing power consumption and fulfilling the purpose of prolonging service life.

Description

technical field

[0001] The invention belongs to digital display devices such as digital photo frames, and in particular relates to an energy-saving control method of a digital photo frame capable of automatically controlling a display mode and having a high-efficiency energy-saving effect, and a digital photo frame adopting the method. Background technique

[0002] At present, most digital photo frames on the market are powered by an external AC power supply, so the photo frame body must be close to the power outlet, which not only restricts the placement and portability, but also easily damages the overall appearance of the digital photo frame due to the power cord. . On the other hand, since the power consumption of the internal processing chip and the display screen of the digital photo frame is relatively large, it will be difficult to maintain long-term use if it is powered by a battery. In view of this, how to provide a digital photo frame that can save power consumpt...
