[Analysis Case] Analysis of Organic EL (OLED) Emission Layer

Quantitative evaluation of the guest in the light-emitting layer and film thickness is possible.

Organic EL displays are advancing towards practical use by leveraging advantages such as high brightness, high-resolution color, and thinness due to their self-emission principle. In the emission layer, guest molecules are doped into host molecules to enhance the emission efficiency. In this study, we identified the emission layer materials for red pixels in organic EL display elements. Additionally, we conducted thickness evaluation of the emission layer using a newly developed step gauge and quantified the guest materials within the emission layer. This allows for qualitative and quantitative analysis of guest molecules in the emission layer, as well as evaluation of the thickness of the emission layer.
