DuPont Display Enhancements Awarded Foundational Patent for Display Bonding Technology
Manufacturing Breakthrough Enables More Rugged & Readable LCD and Touch Screen Displays
DuPont Display Enhancements, Inc. (DuPont) has been awarded a new patent based on a manufacturing method for bonding Liquid Crystal Displays (LCD) and touch screens or cover glass. U.S. Patent No. 8,468,712, entitled “Method for Bonding a Transparent Substrate to a Liquid Crystal Display and Associated Device,” covers a foundational process methodology for producing optically bonded displays, utilizing a dam and fill technique to apply DuPont™ Vertak™ optical bonding adhesive. Growth in the use of optical bonding has been dramatic over the past few years because it improves display durability, readability in bright lighting conditions and allows greater design flexibility.
The proprietary dam and fill technique DuPont developed is used to ensure a consistent, uniform bond gap and provides superior adhesive flow control resulting in a high-quality, high-yield bonding process. DuPont was previously awarded a counterpart patent in China and is currently pursuing additional international counterpart applications.
“We are very pleased to announce the issuance of this patent,” said William S. Bandel, global business director, DuPont Display Enhancements. “It affirms our continuing commitments to driving innovation and maintaining our position of industry leadership for advanced optical bonding display technology.”
