Title:
REPAIR METHOD AND APPARATUS OF LIGHT EMITTING DIODE USING QUANTUM DOT COATING
Document Type and Number:
WIPO Patent Application WO/2011/030993
Kind Code:
A1
Abstract:
The present invention relates to a repair method and apparatus of a light emitting diode for improving a yield rate and repairing a light emitting diode which is selected as a defective product into a high-quality light emitting diode of which the emission color or brightness is improved, by measuring an emission property value of a manufactured light emitting diode and forming a quantum dot layer on the light emitting diode which is selected as the defective product. According to one aspect of the present invention, the repair method of the light emitting diode comprises the steps of: measuring the emission property value of the light emitting diode; determining the corresponding light emitting diode of which the measured emission property value is out of a target range as a defective light emitting diode; and forming a quantum dot layer on a top layer of the defective light emitting diode.
