Light-emitting structures
View Patent ↗Light-emitting structures of reduced size are realized with combinations of light-emitting diodes, resistive and conductive films, and interconnect members. Other embodiments are provided which simplify fabrication and assembly.
1. A light-emitting structure, comprising:
a plurality of light-emitting diodes each having an anode and a cathode and each configured to emit a respective color of light;
a plurality of resistive members spaced over at least one of said anode and said cathode of each of said diodes wherein each of said resistive members has a different resistance;
at least one conductive contact carried on each of said resistive members; and
a conductive wire coupled through a contact to a respective one of the resistive members of each of said diodes to thereby form an interconnected string of diodes that will each carry a respective current when a voltage is applied to said wire.
2. The structure of claim 1 , further including a conductive film inserted between each of said resistive members and its respective diode.
3. The structure of claim 1 , wherein each of said resistive members has a resistivity and a cross section configured to realize its respective resistance.
4. The structure of claim 1 , wherein said wire has a substantially flat cross section.
5. The structure of claim 1 , wherein each resistive member comprises a resistive film.
6. The structure of claim 1 , wherein each resistive member comprises a thin film resistor.
7. The structure of claim 1 , wherein each resistive member comprises a thick film resistor.
8. The structure of claim 1 , wherein said light-emitting diode is a semiconductor light-emitting diode.
9. The structure of claim 1 , wherein said light-emitting diode is an organic light-emitting diode.
10. The structure of claim 1 , wherein said light-emitting diode is a polymer light-emitting diode.
