摘要:
It is an object of the present invention to avoid the above-mentioned problems and provide a multicolor OLED display with improved power efficiency that reduces the need for precisely patterning one or more of the OLED layers. This object is achieved by an OLED display having at least red, green, and blue colored pixels, including a magenta light emitting layer provided over a substrate for red and blue pixels and a green light emitting layer provided over the substrate for producing at least a green pixel. It is also achieved by first and second color filters in operative relationship with the magenta light-emitting layer to respectively produce red and blue pixels.
