Organic light emitting display

Abstract

An organic light emitting display is capable of reducing variation in power transmitted to pixels to reduce or prevent non-uniformity of brightness from being generated. The organic light emitting display includes a pixel including a red sub pixel, a green sub pixel, and a blue sub pixel and first pixel power source lines for supplying a first pixel power from a first pixel power source to the red sub pixel, the green sub pixel, and the blue sub pixel, wherein the first pixel power source lines coupled to at least two different color sub pixels of the red, green and blue sub pixels have different widths. The first pixel power source lines have widths that may correspond to a voltage drop of the first pixel power source or may correspond to deterioration of the respective sub pixels to which they are coupled.

1 . An organic light emitting display, comprising:
 a pixel comprising a red sub pixel, a green sub pixel, and a blue sub pixel; and   first pixel power source lines for supplying a first pixel power from a first pixel power source to the red sub pixel, the green sub pixel, and the blue sub pixel, wherein the first pixel power source lines coupled to at least two different color sub pixels of the red, green and blue sub pixels have different widths.   
     
     
         2 . The organic light emitting display as claimed in  claim 1 , wherein the widths of the first pixel power source lines are in accordance with voltage drop of the first pixel power source. 
     
     
         3 . The organic light emitting display as claimed in  claim 1 , wherein the widths of the first pixel power source lines correspond to deterioration of the respective sub pixels to which they are coupled. 
     
     
         4 . The organic light emitting display as claimed in  claim 1 , wherein the first pixel power source lines coupled to the blue sub pixels have a largest width among the first pixel power source lines. 
     
     
         5 . The organic light emitting display as claimed in  claim 1 , further comprising:
 a data driver for transmitting data signals to the pixel; and   a scan driver for transmitting scan signals to the pixel.   
     
     
         6 . The organic light emitting display as claimed in  claim 1 , wherein the first pixel power source lines coupled to the green sub pixels have a smallest width among the first pixel power source lines. 
     
     
         7 . The organic light emitting display as claimed in  claim 1 , wherein the first pixel power source lines comprise a first main pixel power source line electrically coupled to a first sub pixel power source line. 
     
     
         8 . An organic light emitting display comprising:
 a plurality of pixels, each of the pixels comprising a red sub pixel, a green sub pixel, and a blue sub pixel;   a data driver for transmitting data signals to the pixels; and   a plurality of power lines coupled to the sub pixels, wherein the width of the power lines coupled to the blue sub pixels are larger than the width of the power lines coupled to the red and green sub pixels.   
     
     
         9 . The organic light emitting display as claimed in  claim 8 , wherein the width of the power lines coupled to the green sub pixels are smaller than the width of the power lines coupled to the red sub pixels.
