Embodiment Construction

[0024] Since not all the additional functions of the electronic device are always in operation, the electronic device does not actually require such a high amount of power. In particular, at present, the charging efficiency of electronic products is very important. Users hope that the electronic products can be fully charged as soon as possible on the corresponding sockets with charging functions. Socket with charging function. Therefore, in order to effectively and fully distribute the power in the electronic device in the limited power supply, and to allow the charging socket to have a higher charging power, in order to fully charge the electronic products connected to the charging socket as soon as possible, the present invention implements The electronic device of this example uses dynamic power management to transfer the idle power of the backlight light source and the idle power of the data connection port not connected to the external data load to the charging controlle...

Abstract

The invention discloses an electronic device and a power adjusting method thereof. The electronic device comprises at least one data connection port, a charging controller, at least one charging connection port and a power controller. The charging controller controls the charging power of at least one charging connection port; the power controller is directly or indirectly electrically coupled with the at least one data connection port and the charging controller; when the power controller judges that the at least one charging connection port is connected to an external to-be-charged load andjudges that one of the at least one data connection port is not connected with an external data load, the first idle power corresponding to the at least one data connection port which is not connectedto the external data load is allocated to the charging controller for use. The power is effectively distributed in the limited power supply power, so that the charging connection port can quickly charge the external to-be-charged load with better power, and the original display function and the data transmission function of the electronic device are maintained.

Description

technical field [0001] The invention relates to a power management technology, and in particular to an electronic device with a display function and a power adjustment method used therein. Background technique [0002] With the advancement of technology, electronic devices with display functions (such as home TVs, monitors, etc.) have added many additional functions in addition to increasingly sophisticated display functions. Additional functions can be, for example, High Dynamic Range Imaging (HDR) functionality that improves image contrast and color vividness, data transfer in Universal Serial Bus (USB) 2.0 / ISB 3.0 / USB typc-C Function and fast charging function (currently commonly used fast charging function can be divided into BC1.2 and power delivery (Power Delivery; PD) two charging specifications), wireless networking function, set-top box function, etc. [0003] Usually, hardware modules corresponding to additional functions are configured on the main board of the el...
