Embodiments of this disclosure disclose a display panel and a display device including the display panel. The display panel includes a base substrate, the base substrate including a display area and a non-display area around the display area, a touch electrode layer on the base substrate, the touch electrode layer being within the display area of the base substrate, and a plurality of signal lines electrically connected with the touch electrode layer, the plurality of signal lines being distributed within a first area of the non-display area adjacent to the display area. The display panel further includes a plurality of outer dummy traces within a second area of the non-display area, the second area is between the first area and an outer border of the non-display area, and the plurality of outer dummy traces and the plurality of signal lines are separated from each other.

Disclosed is a method for controlling a plurality of light-emitting devices. The method includes at least: inputting group information into a respective light-emitting device, the group information to be inputted corresponds to a seat in a venue, on which the respective light emitting device to be positioned; and selectively controlling illuminating or extinguishing of groups of light-emitting devices, in accordance with the group information, to present an image over the plurality of light-emitting devices positioned on seats in the venue of an event during a particular period of a group-performance presentation.

A current-generated photo-luminescent hybrid sign is provided that includes one or more light emitting elements within a channel in the frame to evenly distribute light, while at the same time energizing a photo-luminescent glow material in case of power outage. A method of use of the sign is also provided.

An apparatus includes a support member forming a plurality of seats, wherein each seat is adapted to secure an upper end of a yard stake. The support member is further adapted to support at least two retainer arms, and each retainer arm has a distal end including a hook adapted to secure an edge of a display object. The apparatus may be used to assembly a display easel, such as may be used to display a yard sign. The support member may be a rigid block or a wire bracket. A kit may include some or all of the components of a display easel. The support member may be elevated above the ground using yard stakes.

Architectural tiled panel systems composed of at least one sensory output tile module and a plurality of non-sensory-output tile modules. Each sensory output tile module includes any one or more of a variety of electronic devices, such as a video display device, an audio speaker, and an illumination device (e.g., an LED or light bulb), among others. Each non-sensory-output module includes a presentation face that is visually appealing. The non-sensory-output tile modules can be used to provide aesthetic surrounds for each of one or more sensory output tile modules and/or groups of sensory output tile modules. In some embodiments, a plurality of video display type sensory output tile modules are grouped together and controlled to provide a larger mosaicked video display. In some embodiments, abutting tile modules are secured together using connectors having a latch mechanism for each tile module connected thereby.

A free-standing vertical structure is described including at least one wall structure having a plurality of live plants removably secured thereto. The wall structures may also include non-botanic media in combination with the plurality of plants such as traditional media, to form a new mixed media format for conveying information, herein referred to as botanic media. The plurality of plants may be configured to surround the non-botanic media to create a frame or border. The plants may also be arranged and configured to display information themselves. The non-botanic media and/or plants are configured on the wall structure to convey information readily perceivable by a passerby. The plants are preferably hydroponically-fed with nutrients and water from an irrigation system.

An outdoor display screen includes a housing, a display screen, a control module, a heat dissipation module, and a power supply component. A first cavity and a second cavity are disposed on the housing. The display screen, the control module, and the power supply component are mounted in the first cavity, and the heat dissipation module is mounted in the second cavity. A cable-through hole is disposed on the housing. An air exhaust vent connected to an air intake vent of an internal circulation path and an air intake vent connected to an air exhaust vent of the internal circulation path are disposed in the first cavity to form an internal circulation heat-dissipation air duct. An air intake vent and an air exhaust vent are disposed in the second cavity to form an external circulation heat-dissipation air duct.

A solar powered vehicle topper unit and systems and methods for the same are provided. A solar energy harvesting device is electrically connected to an electronic display within a housing. The solar energy harvesting device is located above the housing. The solar energy harvesting device has a first footprint, and the housing has a second footprint which is smaller than the first footprint.
