BACKGROUND

Displays comprising a plurality of light-emitting elements (such as light-emitting diodes, or “LEDs”) are used for the display of information. For example, dynamic message displays can comprise an array of light-emitting elements configured to display information. In some examples, individual displays are formed from a plurality of smaller display modules that are operated together to form a larger display.

SUMMARY

The present disclosure describes a face covering structure for a display module. The face covering structure (also referred to as the Face cover) provides shading of the light-emitting elements of the display module, similar to louver blades in conventional displays. The Face cover also provides enhanced impact protection and improved contrast. In some examples, the Face cover can allow the overall display to meet industry standards corresponding to the application of the display (e.g., transportation standards if the display is being used as a transportation information sign) with respect to impact resistance and contrast in a single simple structure that does not require secondary optics or many of the other more complicated solutions that have been used in displays.

The present disclosure describes a display module that includes a plurality of light-emitting elements and supporting electronics coupled to one or more mounting structures. The plurality of light-emitting elements are grouped into a plurality of pixels each comprising a grouping of one or more of the plurality of light-emitting elements, the pixels arranged in a pixel array on a display face to display one or more of textual, graphical, or video information. The display module also includes a face cover mounted to the one or more mounting structures and positioned in front of at least a portion of the display face. The face cover includes a plurality of moguls arranged in a mogul array, wherein each mogul is positioned in front of and proximate to a corresponding one of the plurality of pixels so that the mogul covers at least a portion of the corresponding one of the plurality of pixels, and a set of one or more light-emitting openings in each mogul, each positioned relative to a corresponding one or more of the light-emitting elements to permit light emitted from the corresponding one or more of the light-emitting elements to pass through the mogul.
