Title:
METHOD AND APPARATUS FOR REPAIRING A LIGHT-EMITTING DIODE USING A QUANTUM-DOT COATING
Document Type and Number:
WIPO Patent Application WO/2011/062362
Kind Code:
A2
Abstract:
The present invention relates to a method and apparatus for repairing a light-emitting diode, which involve measuring the value of light-emitting characteristics of a produced light-emitting diode, determining the level of the measured value of the light-emitting characteristics, and coating the light-emitting diode with a quantum-dot mixture solution to form a quantum-dot layer, thereby repairing the light-emitting diode to form a good product with improved color of the emitted light and luminance, and improving yield. The method for repairing a light-emitting diode according to the present invention comprises the following three steps: measuring the value of light-emitting characteristics of a produced light-emitting diode, and determining the level of the measured value of the light-emitting characteristics; determining a repair quantum dot corresponding to the level of light emission; and forming a quantum-dot layer, corresponding to the repair quantum dot, on the top layer of the light-emitting diode.
