Abstract
An electronic device has a display screen and a driver chip disposed on a driver area of the display screen. A fan-out area of the display screen has interconnects configured to provide electrical accesses to display elements of the display area. The driver chip includes a first edge, a second edge, and a row of electronic pads proximate to the first edge. The electronic pads have a first subset of end pads at a first end of the first row, a second subset of end pads at a second opposite end of the first row, and a subset of intermediate pads located between the first subset and second subset of end pads. The first subset of end pads physically contact a first subset of interconnects from the first edge, and the subset of intermediate pads physically contact a second subset of interconnects from the one or more second edges.
