Abstract

Disclosed herein are display systems with multiple display packages. In some examples, a first display package includes a first LED die and a first backplane die. The first LED die includes a wire interface that is symmetric about a first plane. The first backplane die includes input/output (I/O) pads that are electrically connected to the wire interface and symmetric about a second plane, perpendicular to the first plane. A similarly configured second display package includes a second LED die with a wire interface identical in layout to that of the first LED die, and a second backplane die with I/O pads identical in layout to that of the first backplane die. The second LED die can be positioned with respect to the second backplane die as a mirror reflection across the second plane of the position of the first LED die with respect to the first backplane die.

Dependent claims

A display system comprising:

a first display package comprising:
a first light emitting diode (LED) die including a wire interface, wherein the wire interface is symmetric about a first plane such that wires carrying the same data are mirrored across the first plane;
and
a first backplane die including a set of input/output (I/O) pads electrically connected to the wire interface of the first LED die, wherein the set of I/O pads is symmetric about a second plane perpendicular to the first plane and is located near a center of the first backplane die;
and
a second display package comprising:
a second LED die including a wire interface identical in layout to the wire interface of the first LED die;
and
a second backplane die including a set of I/O pads identical in layout to the set of I/O pads of the first backplane die, wherein the set of I/O pads of the second backplane die is electrically connected to the wire interface of the second LED die, and wherein a position of the second LED die with respect to the second backplane die is a mirror reflection across the second plane of a position of the first LED die with respect to the first backplane die.
