Forming organic light emitting device displays on thinner substrates

Abstract

An organic light emitting device display may be formed with a first layer having standard thicknesses. The first layer may be manufactured to include the organic light emitting device material. The first layer may be secured to a second layer to form a panel. Thereafter, the resulting panel can be subjected to a grinding operation to reduce the thickness of the first layer.

What is claimed is:  
     
         1 . A method comprising: 
 forming an organic light emitting material on a first layer; and    grinding the first layer, with the organic light emitting material formed on the substrate, to a reduced thickness.    
     
     
         2 . The method of  claim 1  including securing the first layer to a second layer and then grinding the first layer to a reduced thickness.  
     
     
         3 . The method of  claim 1  including flattening said first layer before grinding said first layer.  
     
     
         4 . The method of  claim 3  including temporarily securing said first layer to a second layer, flattening said first layer, and then grinding said first layer to a reduced diameter.  
     
     
         5 . The method of  claim 4  including releasing said first layer from said second layer.  
     
     
         6 . The method of  claim 4  including temporarily securing said first layer to said second layer using an adhesive.  
     
     
         7 . The method of  claim 6  including providing a release layer between said second layer and said adhesive.  
     
     
         8 . The method of  claim 1  including flattening said first layer temporarily while grinding said first layer.  
     
     
         9 . An organic light emitting display comprising: 
 a front plate;    a back plate secured to said front plate; and    said front plate having a thickness of less than 0.5 millimeters and a ground exterior surface.    
     
     
         10 . The display of  claim 9  wherein said front plate is formed of glass.  
     
     
         11 . The substrate of  claim 9  wherein said back plate is formed of ceramic.  
     
     
         12 . The display of  claim 11  including a layer of adhesive on the exterior of said back plate.  
     
     
         13 . A device comprising: 
 a glass substrate;    a back plate secured to said glass substrate; and    said glass substrate having a thickness of less than 0.5 millimeters and a ground exterior surface.    
     
     
         14 . The device of  claim 13  including a ceramic back plate.  
     
     
         15 . The device of  claim 13  including a layer of adhesive on the exterior of said back plate.
