    摘要： A power circuit according to the present disclosure may include a multiplexer connected to a first power line and a second power line and selecting and outputting one of a first voltage supplied through the first power line and a second voltage supplied through the second power line. Further, the power circuit may include a first power circuit which generates a first driving voltage and a second driving voltage by using a voltage supplied from the multiplexer, recognizes whether there is the first voltage supplied through the first power line, and does not output the first driving voltage when the first voltage is not recognized.
