The invention relates to a system and a display device for charging a portable electronic device. The display device comprises a first connection interface, a power supply device, a storage device, a first switch and a first control unit, wherein the first connection interface comprises a first voltage transmission end point; the storage device is used for storing functional messages; the first switch is coupled with the first voltage transmission end point and the storage device; the first control unit is coupled with the first switch, and is used for controlling the first switch to be selectively connected to the power supply device or the storage device; when the first connection interface is coupled with a second connection interface, the first voltage transmission end point is coupled with a second voltage transmission end point, and the first control unit controls the first switch to make the power supply device coupled with the first voltage transmission end point. The system and the display device can be used for charging the portable electronic device.
Description
【Technical field】 [0001] The present invention relates to a system and a display device for charging a portable electronic device, especially a system and a display device for charging a portable electronic device according to the presence or absence of an effective connection between the display device and the system . 【Background technique】 [0002] At present, many portable electronic devices are equipped with video function or other functions that require a large amount of data. In order to implement these functions, these portable electronic devices are also equipped with data transmission interfaces to perform necessary functions such as information exchange with other external devices. However, when these functions are turned on, the power consumption rate of the portable electronic device itself will also increase, and the use time of the portable electronic device will easily encounter a bottleneck when there is no external power source to charge it. 【Content of ...
