Abstract: According to examples, systems and methods for implementing a conductive trace via laser direct structuring (LDS) and a light-emitting diode (LED) via surface-mount technology (SMT) on a carrier structure of a display device are described. A method may include printing a conductive trace onto a carrier, mounted a light-emitting diode (LED) onto the carrier, and attaching a flexible printed circuit (FPC) to the carrier, wherein the light-emitting diode (LED) is communicatively coupled to the flexible printed circuit (FPC) via the conductive trace.

Abstract: Antenna systems for near-eye devices are described which include multiple resonance sections fed by a single parasitic element. In one example, an antenna has multiple resonance sections which include an open-ended slot antenna section that resonates within a 2.4 GHz frequency band. In one example, the antenna has a monopole section and a dipole section which both resonate within a 5 GHz to 7 GHz frequency band. In one example, a floating dipole is created by locating an open-ended slot antenna parallel to a monopole antenna, where both antennas share the same electrical feed. In one example, multiple resonance sections on one side of a printed circuit board (PCB) are simultaneously electrically fed by a single parasitic element on the other side of the PCB.
