Abstract:
A two-dimensional visual display of rectangularly shaped light-emitting diodes surface-mounted on a printed circuit board, said display comprising:a printed circuit board having pairs of solder-coated conductive mounting pads, each pair of pads having a respectively corresponding anode and cathode of a rectangular light-emitting diode surface-mounted thereon with reflowed solder connections, each diode providing a dot of output light when activated, said rectangular light-emitting diodes being disposed in a two-dimensional row and column overlapping herringbone pattern array where rectangular diodes in each row are all parallel to one another but are all oblique with respect to diodes in adjacent rows, and such that at least one of the ends of each of the light-emitting diodes in a row is approximately centered with respect to a light-emitting diode in an adjacent row the diodes in each successive row slanting away from those in the other adjacent row or rows.
