Abstract
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.
Claims23
An electronic device comprising:
- an electronic component housing;
- at least one electronic component positionable within said component housing;
- said component housing defining an area for receiving a solid substrate;
- and
- at least one set of electrical contacts positioned within said substrate receiving area, and contained by said component housing, said contacts adapted for spring-load mating with a substrate positioned within said area.
A display device comprising:
- a scrambler having a plurality of reflector partitions therein;
- at least one LED positionable within certain of said plurality of partitions;
- and
- a plurality of spring loaded electrical contacts positioned at peripheral locations around a bottom surface of said scrambler, said electrical contacts in electrical communication with substrates in mating relationship within said peripheral locations.
A method of constructing an LED display, said method comprising:
- mating a substrate against a bottom surface of a housing for distributing light from LEDs positioned within said housing, said substrate having thereon a plurality of LEDs, said LEDs becoming positioned within said housing when said substrate is so mated;
- and
- maintaining said mating relationship by at least one set of spring loaded contacts applying force between said substrate and said housing.
A substrate for supporting LEDs thereon, said substrate comprising:
- a plurality of spaced apart LEDs, each LED having electrical leads extending therefrom, and each LED for insertion into a reflector area of a light scrambler;
- and
- a plurality of electrical contacts positioned at the periphery of said substrate, said contacts each operable for spring-loaded contact with said light scrambler.
An LED display comprising:
- means for supporting a plurality of LEDs;
- means separate from said supporting means for physically distributing light from LEDs supported on said supporting means;
- means for flexibly locking said supporting means to said distributing means;
- and
- means, including said flexibly locking means, for transferring electrical control signals to said LEDs from a separate control board via a surface solder connection on said separate board.
