Biotoxicity Test of Materials in Crystal Liquid Displays

The liquid crystal display (LCD) of a notebook personal computer (PC) contains a complex array of organic compounds (liquid crystal materials) of which the specific formula are normally kept confidential by the manufacturers. Toxicities for most of the materials are unknown. The biotoxicities of the liquid crystal materials from LCDs of a variety of notebook PCs are being tested using several testing methods. The results will be published in the near future.
