A display module according to claim 3 , wherein the first beveled portion is beveled at a first bevel angle corresponding to a first viewing angle for the first direction and the second beveled portion is beveled at a second bevel angle corresponding to a second viewing angle for the second direction.
5. A display module according to claim 3 , wherein the second direction is perpendicular or substantially perpendicular to the first direction.
6. A display module according to claim 3 , wherein the first direction is a horizontal or generally horizontal direction and the second direction is a vertical or generally vertical direction.
7. A display module according to claim 1 , wherein the face cover protects the plurality of light-emitting elements and the supporting electronics from damage due to impact from an object striking the display face of the display.
8. A display module according to claim 1 , wherein the face cover provides for improved contrast of the textual, graphical, or video information displayed by the light-emitting elements.
9. A display module according to claim 1 , wherein the face cover comprises a plurality of moguls arranged in a mogul array, wherein each mogul is positioned in front of 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.
10. A display module according to claim 1 , wherein the face cover comprises one or more alignment structures to align the light-emitting elements in a specified orientation relative to a corresponding one of the one or more light-emitting openings.
11. A display module according to claim 10 , wherein the one or more alignment structures are coupled to a rear face of the face cover.
12. A display module comprising:
a plurality of light-emitting elements coupled to one or more mounting structures;
wherein 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;
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 comprising:
a set of one or more light-emitting openings for each of the plurality of pixels, each set of one or more light-emitting openings is positioned relative to a corresponding one of the plurality of pixels to permit light emitted from the grouping of one or more of the light-emitting elements of the corresponding pixel to pass through the face cover; and
a plurality of bores in the face cover, each bore surrounding at least a portion of a corresponding light-emitting opening, wherein each bore comprises a first beveled portion positioned in a first direction relative to the corresponding light-emitting opening to control a first viewing angle in the first direction from the corresponding light-emitting opening and a second beveled portion positioned in a second direction relative to the corresponding light-emitting opening to control a second viewing angle in the second direction from the corresponding light-emitting opening.
13. A display module according to claim 12 , wherein the first beveled portion is beveled at a first bevel angle corresponding to the first viewing angle for the first direction and the second beveled portion is beveled at a second bevel angle corresponding to the second viewing angle for the second direction.
14. A display module according to claim 12 , wherein the second direction is perpendicular or substantially perpendicular to the first direction.
15. A display module according to claim 12 , wherein the first direction is a horizontal or generally horizontal direction and the second direction is a vertical or generally vertical direction.
16. A display module according to claim 12 , wherein the face cover protects the plurality of light-emitting elements and the supporting electronics from damage due to impact from an object striking the display face of the display.
