Abstract
The present invention has provided a method for fabricating a white-light organic light-emitting diode (OLED) which allows single emitting layers and micro-molecular materials to be formed on the substrate. The white-light OLED includes a white organic emitting layer, a first electrode nearby the first surface of white organic emitting layer, and a second electrode nearby the second surface of white organic emitting layer. The white organic emitting layer is formed by mixing organic light-emitting dyes of white light combination with a micro-molecular substrate via a solution manufacturing process.
Claims10
A white-light organic light-emitting diode comprising:
- a white organic emitting single layer having mixed organic light-emitting dyes of white light combinations into a micro-molecular substrate by a solution manufacturing process, said white organic emitting single layer being a single emissive layer;
- a first electrode having a hole transport layer positioned adjacent a first surface of said white organic emitting layer;
- and
- a second electrode having an electron transport layer positioned adjacent a second surface of said white organic emitting layer, said organic light-emitting dyes comprising a mixture of red dyes and green dyes and blue dyes, said red dyes being 0.01 to 10 weight percent of the layer, said blue dyes being 0.01 to 30 weight percent of the layer.
