Abstract
A LED driving system for driving a LED matrix. The LED driving system includes an interconnection structure having a first surface and a second surface opposite to the first surface and a plurality of driver dies/chips attached to the first surface of the interconnection structure. The LED matrix is divided into a plurality of sub LED matrix sections that are attached to the second surface of the interconnection structure. The interconnection structure is configured to electrically couple each one of the plurality of sub LED matrix sections to a corresponding one driver die/chip in the plurality of driver dies/chips.
