Generally, a media box refers to a device that maximizes the display effect by combining a show case and a display device.

In such a media box, a window of a showcase, which is conventionally formed of a polygon, is made of a transparent display panel, and text information is displayed in the empty space while an article placed inside is displayed.

Particularly, in recent years, an LCD panel for upgrading the media box to reproduce an image of a specific item and a transparent display panel for displaying text information are horizontally arranged horizontally inside the showcase so that the display image and the information are displayed together Media boxes were also presented.

However, such a media box has a problem in that a plurality of display panels are overlapped and images and information of an exhibition product are displayed in the same direction, overlapping colors depending on the three primary colors of light and an additive method.

Accordingly, in order to solve such a problem, a method of recognizing the positions of the images reproduced through the respective panels and controlling the colors of one side image according to the navy color method or the color matching method when the plurality of images are superimposed on each other, However,

There is a problem in that a plurality of transparent display panels arranged side by side are arranged as close as possible to each other.

That is, as each of the display panels is far away, the upper and lower or right and left viewing angles of the distance between the two neighboring panels are secured, and the color appearance changing through each of the panels is directly exposed.

Therefore, the media box should be such that a plurality of display panels are maximally adjacent to each other so that a wide viewing angle can not be ensured.

As a result, the size of the show case must be limited to a small size or the panels should be arranged as close as possible to the adjacent panels. As a result, the panels are located as close to each other as possible.

Furthermore, such a media box requires that a touch panel for controlling the image or text information of the transparent display panel or the general display panel be separately installed,

In particular, there was a problem that the touch panel installed in the window caused the cost to rise and exposed to the heat and the electromagnetic waves without any protection.
