Abstract
Surface mounted LEDs are arrayed in special patterns to provide a relatively high resolution dot-matrix visual display and/or multi-segment character displays. Especially abbreviated solder bonding pads are utilized to obtain a higher density packing of the surface mounted arrays in at least some embodiments. Special anti-glare coatings and structures are employed to reduce ambient light reflections for aircraft instrument applications. Multi-colored display outputs are also provided.
Claims24
A two-dimensional visual display of light-emitting diodes surface-mounted on a printed circuit board, said display comprising:
- a printed circuit board having pairs of conductive mounting pads with corresponding light-emitting diodes surface-mounted thereon, each diode providing a dot of output light when activated,
- said light-emitting diodes being disposed in a two-dimensional row and column array.
