ABSTRACT:
Glare-reduction means are disclosed for use on, in or with a transparent visual display panel structure having an inner display surface which comprises a periodic pattern of luminous elements. The glare-reduction means on an outer surface of the panel structure has an irregularly rippled surface whose spatial frequency spectrum exhibits a suppression of spatial frequencies in a predetermined band of frequencies related to the spatial frequencies of the pattern of luminescent elements to prevent or reduce visible interference between the patterns.
