A vented LED display is described including an LED display panel having a plurality of LEDs disposed thereon and defining a plurality of vent slots between the plurality of LEDs, each of the plurality of vent slots having a vent height. The vented LED display also includes a unitary injection-molded vent having a plurality of louvers and coupled to the LED display panel such that each louver corresponds to at least one vent slot and includes a louver length extending downwardly to at least 75% of the vent height of the corresponding vent slot.

A peg array assembly includes a housing having an opening and defining an internal volume. The assembly also includes a panel having an array of a plurality of apertures formed therethrough. Each aperture of the panel is configured to receive a respective light-transmitting peg and retain the respective light-transmitting peg until the respective light-transmitting peg is selectively removed from the respective aperture. The peg array assembly is configured to selectively receive a mobile device configured to emit light towards the array of the plurality of apertures. A mobile app may display a design template and/or an animation, and systems include the mobile app and the peg array assembly. Methods include accessing design templates and/or animation libraries via the mobile app, inserting light-transmitting pegs through the panel, and displaying a design and/or animation via the light-transmitting pegs and light emitted from the mobile device or other light source.

A display device includes a base structure, a plurality of modules coupled to the base structure, where each of the modules include a plurality of actuator assemblies. Each of the actuator assemblies is individually controllable to move the actuator assemblies between a retracted state and a plurality of extended states. A controller is coupled to each of the modules and is programmed to control the actuator assemblies to move the actuator assemblies between the retracted state and the plurality of extended states.

A true three-dimensional volumetric imaging device includes an imaging light source, a light source adjusting unit, an imaging plate, and a movement driving unit. The light source adjusting unit is arranged between the imaging light source and the imaging plate, and the imaging plate is connected to the movement driving unit. A light beam emitted from the imaging light source is incident onto the imaging plate after being adjusted by the light source adjusting unit, and the movement driving unit causes the imaging plate to oscillate in a direction parallel to an outgoing direction of the light beam emitted from the imaging light source. In the true three-dimensional volumetric imaging device, the true three-dimensional volumetric display of an image is achieved. An algorithm herein is simpler, and a more complete volumetric object can be shown.
