High density energy directing device

An energy directing device comprising:

• one or more energy locations;
• and
• one or more energy relay element stacks;
• wherein each energy relay element stack comprises one or more energy relay elements, each energy relay element comprising a first side and a second side, and each energy relay element being configured to direct energy therethrough;
• wherein the second sides of terminal energy relay elements of each energy relay element stack are arranged to form a singular seamless energy surface;
• wherein the one or more energy relay element stacks are configured to direct energy along energy propagation paths which extend between the one or more energy locations and the singular seamless energy surfaces;
• wherein a separation between the edges of any two adjacent second surfaces of the terminal energy relay elements is less than a minimum perceptible contour as defined by the visual acuity of a human eye having better than 20/40 vision at a distance, greater than the lesser of a height of the singular seamless energy surface or a width of the singular seamless energy surface, from the singular seamless energy surface.
