Abstract (en)
The present invention is directed to a highway electronic display comprising a printed circuit board (PCB) having a plurality of light emitting diodes (LEDs), an optics stage, and a display cover. The optics stage comprises an alignment plate and an optics plate, the alignment plate comprising a sheet of opaque material positioned intermediate the PCB and the optics plate and having a plurality of through holes arranged in rows and columns coincident with the LEDs, and the optics plate comprises a sheet of transparent material having a plurality of optical elements arranged in rows and columns coincident with the LEDs. Each optical element comprises a convex boss protruding outwardly from a rear face of the optics plate proximal the LEDs and a cylinder having a diffusing lens protruding outwardly from a front face of the optics plate distal from the LEDs. Each optical element is formed in a single, unitary piece with the sheet of transparent material. The advantage of providing such a highway electronic display is that the optics plate will be more cost effective to manufacture than manufacturing a plurality of individual optical elements.
