Characterization of Impurities in OLED (Organic Light Emitting Diode) Materials using High Resolution Mass Spectrometry



  June 25, 2019

  8:00 a.m. PDT, 11:00 a.m. EDT, 16:00 BST, 17:00 CEST




The Organo-metallic dyes found in Organic Light-Emitting Diode (OLED) materials enable electronic displays to emit color light directly in response to an electric current without a backlight. A critical aspect of creating high-performance, durable OLED products is the purity management of raw materials, intermediates, and final products that go into OLED based displays. Synthetic by-products, residual starting materials and contamination from outside the manufacturing and development process can significantly impact OLED performance and drastically shorten durability. High-Resolution Mass Spectrometry (HRMS) provides a powerful analytical methodology for detecting and quantifying impurities during the manufacturing process to ensure that OLED materials meet desired performance and durability requirements.
