New Adhesives Improve Displays and Touch Panels

The search for a better adhesive in LCD displays and touch panels has led to the development of a whole new chemistry, involving dual curing by light and humidity. The new adhesives have been developed to help overcome problems associated with traditional adhesives used in displays and touch panels. They reduce the problem of poor readability in bright surroundings, such as direct sunlight, by allowing the glass plate to be bonded directly to the LCD and cured using a combination of light and humidity. Among other things, direct bonding also increases the display’s readability and reduces dust contamination and fogging caused by humidity between the glass plates. It also increases the display’s resistance to shocks and vibrations. The direct bonding made possible by these new adhesives is expected to have significant applications in large area displays used in the automotive, aircraft and military industries.
