Abstract
An electronic device has a display substrate including a display area, a driver area, and a fan-out area. The fan-out area has interconnects providing electrical accesses to display elements of the display area. The device has a driver chip disposed on the driver area. The driver chip includes a first edge adjacent to the display area and multiple pad groups, each pad group including a respective row of electronic pads that is (i) arranged substantially in parallel with the first edge and (ii) electrically coupled to a respective subset of display elements via respective interconnects routed on a respective region of the fan-out area. The pad groups include a first pad group and a second pad group. The first and second pad groups have two different distances from the first edge and correspond to two different subsets of interconnects routed on two non-overlapping regions of the fan-out area.
