It is in operation, and the demand for digital signage continues to increase.

The initial form of digital signage consists of digital information display such as Plasma Display Panel (PDP), Liquid Crystal Display (LCD), and Light Emitting Diode (LED), and stores and reproduces digital media information produced in advance. It was the way. Recently, network type digital signage, in which an advertisement providing device transmits digital media information through a communication network, and the digital signage which receives the digital signal, outputs the received digital media information.

However, digital signage requires a separate exhibition space for installing digital information displays such as plasma display panels (PDPs), liquid crystal displays (LCDs), and light emitting diodes (LEDs).

In addition, since the digital media information output to the digital information display is limited to the size of the screen of the digital information display, the size of the digital media information that can be output through the digital information display is limited. Of course, a digital information display having a large screen size can be used, but as the screen size increases, the installation cost of digital signage increases.

In addition, since the digital information display is installed in the exhibition space in the form of a stand or a wall, and focuses on providing information and advertisement data rather than harmony with the exhibition space, there may be a problem that the digital information display is not in harmony with the exhibition space.
