Analysis of LCD Display Materials

アイテス

Liquid crystal displays use various organic materials, including liquid crystals, sealing materials, encapsulants, and polarizers. Considering the material properties and degradation mechanisms of each component from a chemical perspective is important for product evaluation and failure analysis. This document presents examples of chemical analyses for the components of liquid crystal displays. 【Examples of Chemical Analysis】 ■FT-IR: Principal component analysis ■EDX: Elemental analysis ■GCMS: Liquid crystal component analysis ■HS-GCMS: Outgassing analysis (degradation analysis) and others

Analysis of Liquid Crystal Display Materials
We propose analytical methods tailored to materials and purposes! Here are examples of chemical analysis for each component, such as liquid crystals and sealing materials.

【Other Examples of Chemical Analysis (Partial)】 < Liquid Crystals > ■ GCMS: Analysis of Liquid Crystal Components ■ ICP-AES: Analysis of Metal Elements in Liquid Crystals ■ Results - Liquid crystal components containing cyano groups were used, and metal elements were detected in the liquid crystal. - The polarization of the cyano group may interact with metals and affect liquid crystal driving. < Polarizers > ■ HS-GCMS: Outgassing Analysis (Degradation Analysis) ■ Results - In samples subjected to constant temperature and humidity tests, hydrolysis of cellulose acetate due to the degradation of the polarizer was confirmed. - Hydrolysis of the polarizer is one of the causes of panel display defects. *For more details, please refer to the PDF document or feel free to contact us.
