Color oled display with improved emission |
摘要 |
A color organic light-emitting display having an array of pixels divided into at least two different color pixel sets each color pixel set emitting a different predetermined color, wherein each pixel in the array includes a metallic bottom-electrode layer (12T); an organic EL element (14) including a light-emitting layer (14C) for emitting the predetermined color light and a metallic top-electrode layer (16R) over the organic EL element, spaced from the metallic bottom-electrode layer by a distance selected to improve the emission light output efficiency; and wherein one of the metallic electrode layers is semitransparent and the other one is essentially opaque and reflective; wherein the material for the semitransparent metallic electrode and the reflective electrode includes specific materials; and the thickness of the semitransparent metallic electrode layer and the position of the light-emitting layer between the electrodes are selected to enhance emission light output efficiency. |
