The invention provides a power supply circuit and a display device. The power supply circuit comprises a communication interface and a voltage converting module, wherein an input pin of the communication interface is connected to an outside voltage signal; the voltage converting module is connected with an output pin of the communication interface to be used for converting the outside voltage signal into a preset voltage signal. The power supply circuit and the display device, disclosed by the invention, multiplex the communication interface as a power supply interface to be connected with the outside voltage signal, so that a space is saved, and the voltage converting module can be used for converting the outside voltage signal into the preset voltage signal to be used for power supply for interfaces.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a power supply circuit and a display device. Background technique [0002] Existing display devices usually require 5V (volts) and 12V power supplies, and most of them use several separate power supply boards and communication boards for power supply and communication. The multi-function adapter board includes a power interface, a 5V transfer board, and Interface, 5V transfer switch input interface, 12V conversion interface, 12V transfer switch interface, communication interface, etc. The multi-function transfer board integrates the voltage conversion interface and communication interface on one circuit board. However, the multi-functional adapter board used in the existing display device needs a special power interface, and cannot multiplex the communication interface, resulting in too many interfaces being used. Contents of the invention [0003] The main purpose of the pre...
