Red-green-blue light emission from a thin film electroluminescence device based on parahexaphenyl

For colored flat panel displays electroluminescent organic semiconductors are very promising. A novel means is described for the realization of red, green, and blue (RGB) dots based on an all-organic color transformation technique. The construction of the parahexylphenyl-based electroluminescence device and its combination with suitable matrix dye layers and dielectric mirrors and filters are outlined. The simplicity of the production of the device and the tunability of the emitted colors make this technique technologically attractive.
