The left frame 220b and the right frame 220c have almost similar configurations, and in FIGS. 3 to 5 , the downward direction in the drawing is the front direction of the transparent display apparatus 200 .

The transparent display apparatus 200 of the present invention includes a frame 220 , a display panel 240 , and driving units 230a and 230b.

The frame 220 includes an outer frame 226 that forms the exterior of the front circumference and side surfaces of the transparent display device 200 , a divided frame 226 disposed in contact with the side surface of the display unit, and the transparent display device 200 . an injection frame 228 located around the rear surface of the; and a foam filler 225 filled in the space formed by the outer frame 226 , the divided frame 226 , and the injection frame 228 .

The outer frame 226 forms the exterior of the front circumference and side of the transparent display device 200 as shown in FIG. 3 . Conventionally, a thick frame 220 was used using aluminum, but the present invention uses a thin thin plate-shaped outer frame 226 using SUS (steel use stainless). Aluminum has a problem of low rigidity when it is light but thinly formed, so a material with high rigidity such as SUS is used. In addition, when using SUS, it is possible to form a pattern on the outer surface.

The outer frame 226 is bent in an L-shape as shown in FIG. 3, and in the rear direction from the rear end as shown in FIG. 3 in order to couple with the first coupling part of the injection frame 228 to be described later. It may include a bent edge portion 226c. That is, the outer frame 226 is formed in a U-shape that is folded twice by the front, side, and edge portions 226c, and the rigidity may be increased by folding a plurality of times to form a U-shape.

The division frame 226 is disposed adjacent to the side surface of the transparent display panel 240 to form a boundary between the transparent display panel 240 and the frame 220 . The division frame 226 is a member for forming a space inside the frame 220 by separating it from the transparent display panel 240 , and as it does not require rigidity compared to the outer frame 226 , light aluminum may be used. The end of the split frame 226 may be combined with the injection frame 228 to be described later, and may be combined with the injection frame 228 by folding the end in the rear direction as shown in FIG. 3 .

The injection frame 228 positioned on the periphery of the rear surface of the transparent display device 200 forms a rear structure of the frame 220 and serves to contact the periphery of the front surface of the housing 100 . A gasket comprising a material such as rubber or silicone having elasticity that changes shape when a force is applied to provide a magnet to the injection frame 228 so as to be stably coupled with the front circumference of the housing 100, or 229) can be combined. The gasket 229 may divide its interior into a plurality of spaces as shown in FIG. 3 so as to maintain its shape to a certain extent.

The foam filler 225 is positioned in the inner space composed of the outer frame 220 , the split frame 226 , and the injection frame 228 . The foaming filler 225 injects the foaming solution at high pressure through an injection hole located at the lower end of the frame 220 . Since the foaming solution expands immediately, it can be injected at a high speed and can be injected through two or more holes to ensure uniform injection.

Since the side of the lower frame 220 faces the floor when the predetermined product 10 is installed, it is invisible to the user, so that a solution injection hole may be formed on the side of the lower frame 220 . A cap blocking the solution inlet may be used to prevent the foam filler 225 from being exposed to the outside. In order to provide sufficient space in which the foamed filler 225 is injected, the thickness of the outer frame 226 and the divided frame 226 may be formed as thin as about 1 mm.

The rear cover 260 forms the rear surface of the frame 220 together with the injection frame 228 . The end engages with the injection frame 228 and provides a space for the cable to pass through together with the injection frame 228 and the split frame 226 and glass. The cable connects the first driving unit 230a located in the upper frame 220 and the second driving unit 230b located in the lower frame 220 when the display driving units 230a and 230b are respectively located at the upper and lower portions, or , supplies power to the internal light 270 coupled to the rear cover 260 .

The interior lighting 270 illuminates the interior 120 of the housing as shown in FIG. 3 to provide light so that the interior items are visible. A light source such as an LED can be used as the internal light 270 , and the internal light 270 can be installed only on the left frame 220 and the right frame 220 , or can also be installed on the upper frame 220 and the lower frame 220 . have. When the transparent display panel 240 is not activated and is in a transparent state, the internal light 270 is turned on, and when the transparent display panel 240 is activated and an image is output, the interior 120 of the housing is dark in order for the image to be clear. As a result, the interior light 270 can be turned off.

In the transparent display panel 240 , a light guide plate and a liquid crystal panel 241 may be positioned between a pair of transparent glasses 245 . As shown in FIGS. 4 and 5 , the light guide plate evenly provides light supplied from the light source of the display unit positioned on at least one of the upper and lower sides in the front direction.

Since the display panel 240 of the present invention has a larger size than a laptop or a mobile terminal, it is preferable to supply light in two directions, upper and lower, and light sources may be disposed on the upper and lower portions of the transparent display panel 240, respectively. .

The pair of glasses 245 may be made of different materials. For example, the first glass 245a positioned on the front side may be made of a tempered glass material, and the second glass 245b positioned on the rear surface may be made of a heat insulating material. The reason is that, since the first glass 245 is located at the outermost portion, it is necessary to block external impact. 2 The glass 245b may be used as a heat insulating material.

In addition, an anti-reflection (AR) coating film may be formed on the entire surface of the glass 245 . When external light is reflected by the glass 245 , the luminance and contrast of the image displayed on the transparent display panel 240 may be prevented from being deteriorated.

The edge region of the glass 245 is coupled to the frame 220 , and in particular, the first glass 245a positioned on the front side is fastened with the front part of the outer frame 226 to form a periphery of the first glass 245a . is not visible from the front. A light source or an opaque signal line may be disposed on an edge of the transparent display panel 240 covered by the outer frame 226 .

Next, a first spacer 227 and a second spacer may be disposed on edge regions of the first and second glasses 245a and 245b. Here, the first spacer may control the distance between the first and second glasses 245 , and the second spacer may control the distance between the second glass 245 and the transparent display panel 240 .

The driving units 230a and 230b may be located on at least one side of the upper frame 220 and the lower frame 220 as shown in FIGS. 4 and 5 , and in this embodiment, the first driving unit 230a is located on the upper part and the lower part. may include a second driving unit 230b. The first driving unit 230a and the second driving unit 230b may further include a driving unit frame 223 to distinguish them from an area filled with the foamed filler 225 . As shown in FIG. 4 , the driving unit frame 223 may be configured to extend from the divided frame 226 , that is, to include the divided frame 226 and a single member.

The driving unit frame 223 may be formed by folding the split frame 226 in the rear direction, and a first driving unit 230a and a second driving unit 230b may be formed in a space between the rear cover 260 and the driving unit frame 223 . ) is placed.

When the frame 220 is rotated to open the inside of the product 10 , the luminance of the transparent display panel 240 may be controlled. In addition, the driving units 230a and 230b may control the transparent display panel 240 to display information related to the article 14 stored in the predetermined product 10 . Next, the driving units 230a and 230b may control the transparent display panel 240 so that a light transmitting area and a non-transmissive light transmitting area are simultaneously displayed.

Here, the driving units 230a and 230b may control the transparent display panel 240 so that information related to the article 14 stored in the predetermined product 10 is displayed in the non-transparent area.
