  • Patent number: 11955587
    Abstract: A light emitting diode (LED) package structure includes a glass substrate, conductive through holes, active elements, an insulating layer, LEDs and pads. The glass substrate has an upper surface and a lower surface. The conductive through holes penetrate the glass substrate and connect the upper and the lower surfaces. The active elements are disposed on the upper surface of the glass substrate and electrically connected to the conductive through holes. The insulating layer is disposed on the upper surface and covers the active elements. The LEDs are disposed on the insulating layer and electrically connected to at least one of the active elements. The pads are disposed on the lower surface of the glass substrate and electrically connected to the conductive through holes. A source of at least one active elements is directly electrically connected to at least one of the corresponding pads through the corresponding conductive through hole.
