Abstract: An eye-tracking system may include an optical assembly with integrated micro light emitting diodes. The optical assembly may include a substrate and a flexible printed circuit board assembly bonded to the substrate. Micro light emitting diodes may also be bonded to the substrate. A plurality of conductors may be laminated in the substrate. The conductors may electrically connect the micro light emitting diodes to the printed circuit board assembly. An optically clear adhesive layer may be adhered to the substrate. The optically clear adhesive layer may include an anti-reflective layer and an optical adhesive layer to arranged in a stacked configuration.
