Q.
"What are the differences between Back Lit, Edge Lit and Front Lit illumination?"
A. Back Lit: These are light boxes where
the illumination comes from the light source placed behind a translucent graphic
such a transparency or digital print to illuminate it.
Edge Lit: This is where the light source is placed along the edge of either
specially formulated or engraved acrylic to make the panel "light up".
Front Lit: This is where the illumination is placed in front of the
graphic so the light shines onto the front surface of any graphics printed
onto cardboard or a solid substrate.
A. Back Lit: LED Illumination comes in various forms either in strips, modules or lightboards. Much depends on the size and requirements regarding the depth of the lightbox. The deeper the lightbox the lower the quantity of strips or modules, which in turn can lower the manufacturing costs.
Edge Lit: Illumination comes LED strips either flexible or rigid and sometime modules located on or within the edge of the lightbox again depending on the lightbox profile depth. Ultra slim lightboxes as low as 10mm in depth are illuminated by an edge lit acrylic lightboard or lightsheet. The advantage of a lightboard over strips is the illumination is totally even across the whole surface, due to the CNC engraved grid technology. Edge lit boxes are ultimately slimmer than back lit.
