Abstract
An electronic display includes a matrix of LEDs mounted to a circuit board and selectively operated to produce a message or image. A reflector matrix mounts to the circuit board and provides light pipes which extend forward from each LED to direct its light and provide protection. A lens matrix is mounted to the reflector matrix and it provides convex lenses which are aligned to be received in the light pipes.
