Crystal Clear Adhesives Improve Quality and Strength of LCD Displays and Touch Screens

Posted By ASC, Thursday, November 19, 2015

Adhesives have multiple functions. They bond materials, equalize tension and conduct electricity, but they also provide optical enhancement and re-enforcement when used on LCD displays and touch screens.

Unless screens are attached using adhesives, gaps remain around the edges. Crystal clear adhesives produce an invisible bond and improve viewing quality. They also prevent humidity and dust from affecting internal components.

Light reflection from screens is reduced by as much as two-thirds and color contrast is stronger when crystal clear adhesives are used to seal glass screens. But special crystal clear adhesives can also be used to provide improved shock resistance when combined with aluminosilicate glass.

In tests conducted by Delo Industrial Adhesives, a 13.49 lb. steel ball was dropped onto standard LCD screens and equivalent bonded glass composites from a height of 8.27 feet. Standard LCD screens shattered, but bonded glass composites made with crystal clear adhesive coatings merely bent.
