Backlighting
Backlighting means a translucent image is lit through from behind rather than lit from the front. The picture appears self-illuminated, brilliant and strong even in low ambient light – the classic „light box" effect, but as a modern, flat textile frame.
There are two ways to backlight. With edge lighting (edge-lit) the LEDs sit in the frame profile and feed the light in from the edge – flat and space-saving. With full backlighting (backlit) the LEDs are distributed behind the entire surface; this needs more depth but delivers extra light output on very large or particularly bright displays.
Which option makes sense depends mainly on the frame depth and the brightness required. For most trade-fair and retail displays, edge lighting is the more elegant solution.
