A louver panel for an electronic sign incorporating multiple spaced primary and secondary louvers extending outwardly from a configured substantially planar panel to provide direct shading of the structure adjacent to an LED, to the structure of the louver panel including the louvers and the panel, and to provide shading for all or part of an LED. Spacings of the louvers provide for regions of shade which improve contrast and which in transition between panels camouflage horizontal seams.
