A display device includes a housing with a grid assembly received therein. A plurality of light assemblies is coupled to the grid assembly, for example in a grid pattern to create a dynamic display area. Each of light assemblies has an actuator assembly, with each one of the actuator assemblies being individually controllable to move the corresponding light assembly between a retracted state and a plurality of extended states. A controller is coupled to each of the plurality of light assemblies and programmed to control the actuator assemblies to move the light assemblies between the retracted state and the plurality of extended states.

A system and method for removable or semi-permanent installation of a TOLED display are disclosed. In one embodiment, the system includes a TOLED display that includes a TOLED panel coupled to a cover glass. The system further includes a top hinge assembly and a bottom hinge assembly used to rotatably couple the TOLED display to a support structure to facilitate rotation of the TOLED display to different positions and to provide relatively easy removal of the TOLED assembly.

Self-contained devices, systems and methods for housing holiday lights in the form of icicles, and the like, in self-contained boxes that can easily be mounted and removed around house windows and eaves. The lights can be retractable and extendable from the boxes, and the lights can be remotely controlled by smart phones and the like. The boxes can have displays for holiday messages as well as speakers for playing music and messages.

An energy harvesting system and an indicator using same are disclosed. The disclosed indicator using an energy harvester comprises: an energy harvesting unit including at least one solar cell; a panel unit, which is arranged to face the energy harvesting unit, transmits sunlight and displays guide information; and a light-emitting unit for emitting light at the side surface of the panel unit.

An illuminated sign for a commercial or residential building is provided. The illuminated sign comprises a body having a design portion. The body of the sign includes at least one reflective surface and at least one solar panel along at least one edge of the body of the sign. The solar panel electrically coupled to a charge control that is electrically coupled to a battery. The battery being electrically coupled to a LED driver that controls the electrical current provided from the battery to an LED light strip that is used to illuminate the illuminated sign.

A display device includes a plurality of display modules provided to output visual information, having a bar shape, and sequentially disposed in one direction, a connection unit connecting the plurality of display modules such that the plurality of display modules are relatively moved, and a controller controlling the connection unit to relatively move the plurality of display modules to adjust daylighting using a space between the plurality of display modules.

A solar-powered advertising kiosk can include a frame configured to divide the solar-powered advertising kiosk into one or more sections. The solar-powered advertising kiosk can also include a roof configured to convert sunlight to electricity to power one or more advertising displays, wherein the roof includes a first portion of the frame, and wherein the roof includes one or more solar tents each including one or more solar modules. The solar-powered advertising kiosk can further include a body configured to display one or more images on the one or more advertising displays, wherein the body includes a second portion of the frame.

There is provided a method for forming a three-dimensional decoration on a wall surface, wherein the method comprises: drawing a sketch on the work wall-surface; installing a crack-prevention member on the work wall-surface to suppress a separation between the three-dimensional decoration and the wall surface, wherein the crack-prevention member is disposed in a first region corresponding to the sketch; plastering a cement-mortar in the first region on the work wall-surface so as to embed the crack-prevention member in the cement-mortar, thereby to form a cement-mortar relief; three-dimensionally engraving a front face portion of the cement-mortar relief to form a cement-mortar relief-type decoration as the three-dimensional decoration; and coloring the cement-mortar relief-type decoration using a mixture of silicon as a binder and coloring pigments.

An energy harvesting system and an indicator using same are disclosed. The disclosed indicator using an energy harvester comprises: an energy harvesting unit including at least one solar cell; a panel unit, which is arranged to face the energy harvesting unit, transmits sunlight and displays guide information; and a light-emitting unit for emitting light at the side surface of the panel unit.
