Abstract

A display for full color video includes light emitting diodes (LED's) arranged to increase LED density and thereby achieve enhanced resolution. The matrix is of the type that includes a plurality of physically separate, addressable dice fixed to a substrate. The display of the invention achieves increased density by utilizing dice of at least two distinct predetermined heights which are positioned onto the substrate in a predetermined pattern whereby the heights of adjacent dice differ. In this way, the closeness of inter-die spacing is not limited by the size of a positioning tool for grasping dice adjacent their upper portions.
