Classification: CPC H | IPC G  H

Claim 13:
14. An electrical circuit for driving light emitting diodes (LEDs) comprising:
a substrate including a plurality of scan lines substantially orthogonal to a virtual centerline of the substrate;
a first driver integrated circuit (IC) on a first side of the substrate, the first driver IC including a set of line switches coupled to a first set of the plurality of scan lines along a side of the first driver IC nearest the virtual centerline; and
a second driver IC on the first side of the substrate, the second driver IC including a set of line switches coupled to a second set of the plurality of scan lines along a side of the second IC nearest the virtual centerline;
wherein the first driver IC is configured to control the set of line switches of the second driver IC based on a scanning sequence of the plurality of scan lines;
wherein the scanning sequence is stored in a register via a digital core; and
wherein the scanning sequence is configured to be programmed through a communications interface responsive to signals provided at a data input and a clock input.
