The present invention relates to a technique for displaying method for displaying a charging state of a terminal to be charged by using a real-time gauge in a set-top box embedded in a wireless charging device and, more specifically, to a technique for enabling a user to intuitively check a charging state of a terminal to be charged through a display device by outputting a pulse signal through an LED port provided in a charging control chipset apart from a charging line, when the charging control chipset receives a charging available preparation signal from the terminal to be charged, while the charging control chipset of a wireless charging device and the terminal to be charged adjacent to the outside communicate with each other, counting the outputted pulse signal by a microcomputer mounted in a set-top box, and increasing a charging gauge provided in the display device in association with an increase of the count. According to the present invention, convenience in wireless charging and immersion in the broadcast program can be all maintained by enabling a user to intuitively check a charging state of a terminal to be charged while watching the TV. |
