A display module comprises light-emitting elements coupled to one or more mounting structures and grouped Into a pixels in a pixel array on a display face to display textual, graphical, or video Information, with each pixel comprising a grouping of one or more light-emitting elements. A face cover Is mounted to the mounting structure and is positioned in front of at least a portion of the display face. The face cover comprises a plurality of moguls arranged in a mogul array with each mogul positioned in front of and proximate to a corresponding one of the pixels so that the mogul covers at least a portion of the corresponding pixel, and one or more light-emitting openings in each mogul, each positioned relative to one or more corresponding light-emitting element of the pixel to permit light emitted from the corresponding one or more light-emitting elements to pass through the mogul.

An illuminated floor tile, includes a rear body, an LED lamp panel disposed on the rear body, and a glass cover provided over the LED lamp panel and secured to the rear body by an adhesive layer. The LED lamp panel includes a plurality of lamp beads fixedly arranged on a PCB board. The rear body includes a plurality of supports extending from a bottom hosing and through an opening of the PCB, such that a top surface of the supports is higher than the lamp beads and supports the glass.

An optical film includes a plane and a plurality of dents. The plane has a normal, and the dents are formed on the plane. Each of the dents is asymmetric relative to the normal, wherein each of the dents includes an opening, and the maximum aperture of each of the dents is the caliber of the opening.

The present invention is an optical LED light display incorporating one or more louvers operable to limit the light emission in a specified direction from a LED diode within the LED light display, each louvers being positioned in relation to each LED light element in the LED light display. The specified direction of the light emission may be towards a target audience or a target direction. A method of the present invention that may be implemented by a software program processed by computer processors of a computer device, may be operable to enable the design of the LED display louver for installation in a specific area to enable simultaneous elimination of light trespass and preservation of image quality for the target audience. A LED light display can be manufactured, configured and installed in accordance with the method.

A system may have an exterior display. The exterior display may display symbols that correspond to intended actions for the system or instructions for nearby viewers. The exterior display may include an array of light-emitting diodes, a collimator, a one-way filter to prevent sunlight from washing out the display, and a cover layer. The one-way filter may include a microlens array and a masking layer. The collimator is configured to collimate light from the array of light-emitting diodes and provide the collimated light to the one-way filter. The microlens array receives the collimated light and focuses the collimated light through a plurality of holes in the masking layer. In this way, the majority of display light is passed through the one-way filter towards a viewer. However, the majority of ambient sunlight is blocked by the masking layer, thus preserving a high contrast for the exterior display even in bright sunlight.

An electronic sign having at least one sectional sign assembly, the at least one sectional sign assembly having a signage support structure and an associated compound structural frame, wherein the compound structural frame has a unitary structural foam construction with a plurality of display module receiving bays, each configured for removably latching therein a plurality of display modules, the signage support structure and the associated compound structural frame cooperating when secured together to form a natural airflow cooling path extending from the top to the bottom of sectional sign assembly to provide sufficient cooling to the plurality of display modules when removably mounted within their display module receiving bays.

A display device in which pixels constituted by light emitting elements arranged on a substrate are arranged in a matrix, the substrate comprises: a canopy disposed at the upper or lower end of the pixels; and at least two kinds of anti-reflective components that are formed at a peripheral edge of the light emitting element and with different reflection angles with respect to incident light.

A dynamic message sign includes a front housing defining a viewing window and an interior. A LED assembly is in the interior for displaying a message within a cone of vision. A louver assembly limits the cone of vision. The dynamic message sign may also include a back frame for supporting the front housing and a bracket for setting the front assembly at an angle with respect to the back frame. The LED assembly can include a plurality of LED pixels arranged in rows and columns. The louver assembly can include a plurality of louver racks, each louver rack extending adjacent to a column of LED pixels.

A plurality of LED light sources that are mounted on a front face of a mounting plate are separated from each other respectively being disposed in cells of a partitioning wall. Inner faces of the respective cells are made of a material of low reflectivity. With respect to a normal line direction of the mounting plate, light of the LED light source is viewed, as light being brighter the closer to a back side and darker the closer to a near side on the inner face, in a state of being given gradations by the inner face.
