Abstract

Organic light emitting diode (OLED) devices are disclosed that include a first layer; a backfill layer having a structured first side and a second side; a planarization layer having a structured first side and a second side; and a second layer; wherein the second side of the backfill layer is coincident with and adjacent to the first layer, the second side of the planarization layer is coincident with and adjacent to the second layer, the structured first side of the backfill layer and structured first side of the planarization layer form a structured interface, the refractive index of the backfill layer is index matched to the first layer, and the refractive index of the planarization layer is index matched to the second layer.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An OLED device comprising:
 a first layer;   a backfill layer having a structured first side and a second side;   a planarization layer having a structured first side and a second side; and   a second layer;   
       wherein the second side of the backfill layer is coincident with and adjacent to the first layer, the second side of the planarization layer is coincident with and adjacent to the second layer, the structured first side of the backfill layer and structured first side of the planarization layer form a structured interface, the refractive index of the backfill layer is index matched to the first layer, and the refractive index of the planarization layer is index matched to the second layer. 
     
     
         2 . The OLED device of  claim 1 , wherein the backfill layer comprises a nanoparticle composite. 
     
     
         3 . The OLED device of  claim 1 , wherein the backfill layer is made from a polymerizable composition comprising monomers cured using actinic radiation. 
     
     
         4 . The OLED device of  claim 1 , wherein the backfill layer comprises a silsesquioxane. 
     
     
         5 . The OLED device of  claim 1 , wherein the backfill layer comprises nanoparticles. 
     
     
         6 . The OLED device of  claim 1 , wherein the backfill layer comprises an acrylic coating including silica nanoparticles. 
     
     
         7 . The OLED device of  claim 1 , wherein the backfill layer comprises an acrylic coating including zirconia nanoparticles. 
     
     
         8 . The OLED device of  claim 1 , wherein the planarization layer comprises nanoparticles. 
     
     
         9 . The OLED device of  claim 1 , wherein the planarization layer comprises an acrylic coating including silica nanoparticles. 
     
     
         10 . The OLED device of  claim 1 , wherein the planarization layer comprises an acrylic coating including zirconia nanoparticles. 
     
     
         11 . The OLED device of  claim 1 , wherein the structures of the backfill layer and planarization layer are nanostructures. 
     
     
         12 . The OLED device of  claim 1 , wherein the backfill layer comprises a bilayer of two different materials. 
     
     
         13 . The OLED device of  claim 12 , wherein one of the bilayers comprises an adhesion promotion layer. 
     
     
         14 . The OLED device of  claim 1 , wherein the first layer is an active matrix OLED backplane. 
     
     
         15 . The OLED device of  claim 1 , wherein the first layer is an active matrix OLED color filters on array. 
     
     
         16 . The OLED device of  claim 1 , wherein the first layer is an OLED solid state lighting element. 
     
     
         17 . The OLED device of  claim 1 , wherein the second layer is an active matrix OLED backplane. 
     
     
         18 . The OLED device of  claim 1 , wherein the second layer is an active matrix OLED color filters on array. 
     
     
         19 . The OLED device of  claim 1 , wherein the second layer is an OLED solid state lighting element.
