System and method for surface mountable display
View Patent ↗A system and method is disclosed for allowing a solid substrate, such as a printed circuit board (PCB), to act as the support structure for an electronic circuit. In one embodiment, the LEDs which form a part of a scrambler assembly are constructed on a first substrate and the electrical connections are run to the edges of the substrate and end in electrical contacts positioned thereat. The substrate is then connected to the scrambler package by a series of electrical and mechanical connections to form the LED package. The electrical contacts which are part of the LED package extend from the LED package so as to enable electrical contact with a separate controller substrate.
