A display case door assembly for a temperature-controlled storage device includes a frame defining an opening into the temperature-controlled storage device and a transparent unit coupled to the frame. The transparent unit includes a first vacuum pane, a second vacuum pane, and an evacuated gap between the first and second vacuum panes. The evacuated gap has a predetermined thickness within which a vacuum is drawn, thereby providing a thermal insulation effect for the transparent unit. The transparent unit further includes a plurality of spacers disposed within the evacuated gap and configured to maintain the predetermined thickness of the evacuated gap when the vacuum is drawn therein.

Disclosed in the present invention is a transparent display device. The transparent display device according to the present invention comprises: a frame having first and second apertures; a transparent display panel disposed on the first aperture of the frame; and a control module, disposed on the second aperture of the frame, for controlling the transparent display panel, wherein the frame is installed to cover the front surface of the door unit of a certain product or is separated from the front surface of the door unit of the certain product, and wherein an extension frame extended from an edge of the frame toward the door unit of the certain product can engage with the side of the edge of the door unit of the certain product.

Provided is a refrigerator, which includes a refrigerating compartment, a freezing compartment, and a door assembly. The freezing compartment is adjacent to the refrigerating compartment. The door assembly selectively opens the refrigerating compartment and the freezing compartment. The door assembly includes a glass member defining a frontal exterior thereof and allowing an inside of the refrigerating compartment or the freezing compartment to be seen therethrough when the door assembly is closed, a deposition treated layer formed on a rear surface of the glass member to allow light to partially pass through the glass member, and a transparent plate spaced a predetermined distance from the glass member. Gas for insulation is injected in a space formed between the glass member and the transparent plate, and the space is sealed.

A display device for selectively displaying an at least one multi-dimensional object is disclosed. In at least one embodiment, the display device provides an upper portion and a corresponding lower portion configured for selective engagement with the upper portion, thereby allowing the upper portion to remain in a substantially vertical orientation. The upper portion provides a first frame and an opposing second frame selectively engageable with the first frame. The first frame provides a first aperture, the first aperture having a first window panel spanning the first aperture. The second frame provides a corresponding second aperture sized for approximating the dimensions of the first aperture, the second aperture having a second window panel spanning the second aperture. The first and second apertures cooperate to define an enclosure therebetween for selectively receiving the at least one object therewithin.

A retail electronic product demonstration fixture for demonstrating portable electronic devices. The product demonstration fixture may include an exhibition portion and a base portion. A portable electronic device offered for sale may be affixed to the exhibition portion. The base portion may include an electronic display, an auxiliary battery, and an auxiliary controller. The auxiliary controller may direct power from the auxiliary battery to the electronic display upon determining that a battery within the electronic display has fallen below a particular selected level. Similarly the auxiliary controller may direct power from the auxiliary battery to the portable electronic device offered for sale upon determining that a battery within the portable electronic device has fallen below a selected level.

A transparent display device attached to a predetermined product, displaying article information in the product, advertisement, etc. is disclosed. The transparent display device comprises a frame including an opening; a transparent display panel arranged at the opening; and a control module arranged in an area of the frame to control the transparent display panel, wherein the frame in which the transparent display panel and the control module are arranged is provided to cover a front surface of a predetermined product so as to form a door unit of the predetermined product, and is rotatably moved when the inside of the predetermined product is opened and closed.

A display apparatus comprises a locker, at least one display cabinet, and a PLC system. The PLC system controls a display product transmitted between the locker and the at least one display cabinet, and when the at least one display cabinet is destroyed, the PLC controls the display product transmitted to the locker from the locker.
