Arrangement of color sub-pixels for full color oled and method of manufacturing same

Abstract

A full-color display panel is provided comprising a repeating super-pixel block including four pixel units, wherein each of the pixel units has a first sub-pixel configured to emit a first color light, a second sub-pixel configured to emit a second color light, and a third sub-pixel configured to emit a third color light. The first or second sub-pixel abuts the same-color sub-pixel of the adjacent pixel unit thereof to form at least a double-sized sub-pixel area. The third sub-pixel abuts the same-color sub-pixel of all adjacent pixel units thereof to form at least a quadruple-sized sub-pixel area. The first color light, the second color light, and the third color light are one of emitted through or from respective organic layers of the first color sub-pixel, the second color sub-pixel and the third color sub-pixel.

         1 . A full-color display panel, comprising:
 a substrate; and   a plurality of pixel units formed on the substrate, wherein each pixel unit includes at least three sub-pixels each configured to emit colored light in the pixel unit,   where four pixel units are arranged in a two by two block to form a super-pixel, such that each pixel unit is rotated to define a mirror image arrangement within the super-pixel block, wherein at least one sub-pixel abuts the same color sub-pixel of both the vertically and horizontally adjacent pixel units to form a quadruple-sized sub-pixel group.   
     
     
         2 . The full-color display panel of  claim 1  wherein each sub-pixel has an area. 
     
     
         3 . The full-color display panel of clam  2  wherein the colors of the sub-pixels of each pixel unit are red, green, and blue. 
     
     
         4 . The full-color display panel of  claim 3  wherein the blue sub-pixel area is double the red or green sub-pixel area within each pixel unit. 
     
     
         5 . The full-color display panel of  claim 1  wherein a plurality of super-pixel blocks are arranged on the substrate such that at least two sub-pixel groups are at least quadruple the size of the respective sub-pixel area. 
     
     
         6 . The full-color display panel of  claim 1  wherein a plurality of super-pixel blocks are arranged on the substrate such that at least one sub-pixel group is at least octuple the size of the respective sub-pixel area. 
     
     
         7 . A display panel comprising a super-pixel repeating block comprising:
 four pixel units, wherein each of the pixel units comprises:   a first sub-pixel configured to emit a first color light;   a second sub-pixel configured to emit a second color light;   a third sub-pixel configured to emit a third color light;   wherein the first or second sub-pixel abuts the same-color sub-pixel of the adjacent pixel unit thereof to form at least a double-sized sub-pixel area; and   wherein the third sub-pixel abuts the same-color sub-pixel of all adjacent pixel units thereof to form at least a quadruple-sized sub-pixel area,   wherein the first color light, the second color light and the third color light are one of emitted through or from respective organic layers of the first color sub-pixel, the second color sub-pixel and the third color sub-pixel.   
     
     
         8 . The display panel of  claim 7  wherein the first, second, and third color light is one of red, green, or blue light. 
     
     
         9 . The display panel of  claim 7  wherein each of the pixel units is square. 
     
     
         10 . The display panel of  claim 7  wherein at least one of the sub-pixels is square. 
     
     
         11 . The display panel of  claim 7  wherein at least one of the sub-pixels is rectangular. 
     
     
         12 . The display panel of  claim 7  wherein the display panel is an organic light emitting display panel. 
     
     
         13 . A method of manufacturing a display panel, the method comprising:
 providing a substrate;   simultaneously providing a plurality of first sub-pixels of the display panel, wherein each of the first sub-pixels emits a first light;   simultaneously providing a plurality of second sub-pixels of the display panel, wherein each of the second sub-pixels emits a second light; and   simultaneously providing a plurality of third sub-pixels of the display panel, wherein each of the third sub-pixels emits a third light,   wherein the display panel comprises a plurality of pixel units, each of the pixel units having first, second and third sub-pixels, wherein four pixel units are arranged in a two by two block to define a super-pixel block, such that each pixel unit is rotated to define a mirror image arrangement within the super-pixel block,   wherein the super-pixel block is repeatedly formed on the substrate such that repeating sub-pixel blocks form sub-pixel groups with adjacent sub-pixels having the same color.   
     
     
         14 . The method of  claim 13  wherein simultaneously providing the first, second and third sub-pixels includes using a shadow mask or fine metal mask. 
     
     
         15 . The method of  claim 13  wherein each of the pixel units is square.
