OLED Organic Light Emitting Diode

We started to develop R&D of OLED since 1995 Analysis experiences including reverse engineering reach to more than 5,000 OLED panels. We provide analytical services which can solve the problems in manufacturing process and improve materials with accumulated knowledge for OLED analysis, such as organic materials, composition, multilayer structure, degradation analysis, water permeability etc.

• Water permeability analysis by D-SIMS

  Use of isotope-labeled water, D₂O, and D-SIMS enables us to clarify permeated D₂O profile after exposure in D₂O vapor. This method is promising for evaluating the water permeation behavior both in inorganic films and organic films.

• Determination of multilayer structure of OLED by cross-sectional_TEM

  Organic layers with similar composition can be distinguished by TEM with our original contrast enhancement. By cross-sectional TEM-EDX of the defect which was found in surface SEM, we can reveal the detailed structure and the composition of it.

• TOF-SIMS MS/MS for analysis of degradation product in OLED driving test

  PL line analysis, GCIB-TOF-SIMS, and TOF-SIMS MS/MS were applied to the degradation analysis of OLED in driving test. TOF-SIMS MS/MS revealed the detailed chemical structure of degradation product in the specific depth region in OLED stacks.
