A semi-transparent sign includes a reflective display, multiple layers and a control circuit. The reflective display may be semi-transparent, have a first side subject to a thermal load, have a second side opposite the first side, and configured to generate a plurality of visible images. A heat sink layer may be attached to the first side, be transparent, and configured to carry heat energy away from the reflective display. The thermal layer may be attached to the heat sink layer, be semi-transparent, and configured to reduce an intensity of the thermal load reaching the reflective display. The warming layer may be attached to the second side, be transparent, and configured to heat the reflective display in response to an electric current. The control circuit may be configured to control the electric current to the warming layer based on a temperature signal indicating a temperature of the semi-transparent sign.

The present disclosure describes shelf assemblies having illuminated frames for products including appliances such as refrigerators.

An information display device (1G) attachable to a structure includes a display panel (23) and a surface member (11). The display panel (23) has a display surface and displays information on the display surface. The surface member (11) is disposed on the display surface side of the display panel (23) and is in a state where only the information displayed on the display surface of the display panel (23) is visible through the surface member (11) when the display panel (23) is turned on. The surface member includes a first layer (71) disposed on a front side, and a second layer (72) that is disposed on the display panel (23) side with respect to the first layer (71). The second layer (72) is configured to compensate the difference of transmittance depending on the position on the first layer (71).

A portable cylindrical light box, including a strut, an advertising fabric, a fixed profile and a transparent film. An inner wall of the advertising fabric is sewn with a first silicone strip. An outer wall of the first silicone strip abuts the transparent film. A second silicone strip is adhered to the bending portion of an outer wall of the transparent film. The groove is provided on the strut. An outer wall of the fixed profile is fixed with a light bar including an adhesive layer, a soft base layer adhesively connected to the fixed profile by the adhesive layer, and an LED bead SMD fixed on the soft base layer. The upper and lower ends of the fixed profile are respectively mounted with a bottom plate assembly and a cover plate assembly fixedly connected to the upper end of the fixed profile by screws.
