Method of repairing and apparatus for repairing multi-color organic light-emitting display device

Abstract

A method and an apparatus for repairing short circuits between electrodes of a multi-color organic light-emitting display device. A multi-color organic light-emitting display device having a color-converting filter section is provided. Then a short-circuited part between electrodes in the device is eliminated by irradiating the short-circuited part with a laser beam. The laser irradiation is carried out from the side of the device on which the color-converting filter section is not present. The method is carried out in an environment in which the moisture content is below a certain threshold value such as a vacuum or a dry nitrogen atmosphere.

1 - 2 . (canceled)  
   
   
       3 . A repair apparatus for repairing a short-circuited part between electrodes in a multi-color organic light-emitting display device, the device including a color-converting filter section and an organic light-emitting device, the repair apparatus comprising: 
 short-circuited part detecting means for detecting a short-circuited part from a color-converting filter section side, or the color-converting filter section side and an organic light-emitting device side,    positioning means,    lighting means for lighting of the multi-color organic light-emitting display device, and    a laser irradiation apparatus, wherein laser light irradiated from the laser irradiation apparatus is irradiated from the side of the multi-color organic light-emitting display device on which the color-converting filter section is not present.    
   
   
       4 . The repair apparatus according to  claim 3 , further comprising dry environment means providing a dry environment for within which to carry out the repair of the short-circuited part.  
   
   
       5 . An apparatus for repairing a short-circuited part between electrodes in a multi-color organic light-emitting display device, the multi-color organic light-emitting display device having a cathode, an anode, and a color-converting filter section, the cathode, anode and color-converting section being disposed in different layers, comprising: 
 a lighting device having the multi-color organic light-emitting display device positionable thereon, that illuminates the multi-color organic light-emitting display device;    a microscope that detects a short-circuited part between electrodes in the multi-color organic light-emitting display device;    a positioning device that moves the multi-color organic light-emitting display device to detect the short-circuited part between electrodes in the device; and    a laser that eliminates the short-circuited part by irradiating the part with laser irradiation, wherein the laser irradiation is carried out from a side of the device on which the color-converting filter section is not present.    
   
   
       6 . The apparatus according to  claim 5 , wherein the microscope is an emission microscope.  
   
   
       7 . In combination, a multi-color organic light-emitting display device having a cathode, an anode, and a color-converting filter section, the cathode, anode and color-converting section being disposed in different layers, with the anode being disposed between the cathode and the color-converting filter section; 
 means for detecting a short-circuited part between electrodes in the device; and    means for eliminating the short-circuited part by irradiating the part with laser irradiation, wherein the laser irradiation is carried out from a direction of the cathode toward the anode, and from a side of the device on which the color-converting filter section is not present.    
   
   
       8 . The combination according to  claim 7 , wherein the multi-color organic light-emitting display device is sealed, the short-circuited part being eliminated while in a vacuum or in a dry nitrogen atmosphere, prior to a sealing of the multi-color organic light-emitting display device.  
   
   
       9 . The combination according to  claim 7 , wherein the means for detecting is performed from a side of the device on which the color-converting filter section is present.
