Which of the following allows for good screen durability in infra-red touch technology?

In infra-red touch technology, choosing durable glass material contributes significantly to screen durability. Glass is inherently strong and can withstand normal use, including scratches and impacts, while maintaining clarity and touch sensitivity. This enhances the overall user experience by providing a responsive surface that is also resistant to wear and tear over time.

Thin plastic layering, while lightweight and flexible, may not offer the same level of protection against scratches and damage as glass. Highly flexible membranes can improve touch sensitivity but may compromise durability, especially in high-use environments. Reinforced metal screens, though robust, may not be practical for touch technology due to the lack of a smooth, responsive surface essential for accurate touch input. Thus, the use of durable glass provides the ideal balance between functionality and durability in infra-red touch technology.
