An edgelit display panel assembly comprising a frame (30) supporting a light-diffusive plate (10) and an electric light source (20) or sources disposed along and closely adjacent to at least one edge of that plate (10) for illuminating the whole plate (10) and transmitting light through a major surface of the plate within the frame (30) in use, wherein at least the said one edge of the plate (10) has a light-receiving surface (13,14,15) that is inclined and/or that lies within a recess (12) formed in the edge of the plate (10). Preferably, the or each light source (13,14,15) extends, in the plane of the plate (10), at least partly over the light-receiving surface. In an alternative assembly, the frame (30) comprises a hollow, open channel for accommodating electric circuit components for the electric light source (20), and the channel is closed, in use, by a removable elongate fascia panel connected by an elongate magnet and which preferably also serves to frame (30) the edge of the image-supporting substrate. <IMAGE> |
