Abstract: Disclosed herein is an image sensor package including a printed circuit board, an image sensor electrically coupled to the printed circuit board, a sealing configuration coupled to a front face of the printed circuit board via a first gasket, and a base coupled to a back face of the printed circuit board via a second gasket. Electronic components embedded on the back face of the printed circuit board align with and connect to mating pads surrounding the image sensor on the front face of the printed circuit board. Wire bonds electrically connect the image sensor to the mating pads and the electronic components. The sealing configuration includes a cover attached to a frame surrounding the image sensor. A gap separates the image sensor from abutting the surrounding printed circuit board, which is coupled to the image sensor via the base.

Abstract: An LED visual display apparatus includes a plurality of LED pixels arranged in a generally rectangular array and each having a substantially identical construction. A controller controls groups of the LEDs to produce virtual pixels. In some instances, the construction of each LED pixel consists of 6 to 9 LEDs, inclusive, includes a plurality of red LEDs, a plurality of green LEDs and at least one blue LED, and has more red LEDs than green LEDs. In some instances, the array includes rows of LEDs that consist only of green and blue LEDs which define a repeating green-green-blue pattern. In some instances, the array includes rows of LEDs that consist only of red and green LEDs which define a repeating red-red-green pattern.

Abstract: An apparatus that supports operation of an LED sign includes a backplane that connects a backplane frame output of a first video data processor circuit card to a backplane frame input of a second video data processor circuit card, and also connects a backplane frame output of the second video data processor circuit card to a backplane frame input of a sign interface circuit card. Each video data processor circuit card includes a video source input, and the sign interface circuit card includes a video data output for coupling to distribution boards located at the sign. The backplane architecture provides flexible scalability by permitting the addition of further video data processor circuit cards and further sign interface circuit cards in any desired configuration.
