Why must high-quality capacitive touch screens undergo chemical tempering?

When choosing a PCAP touch screen, in addition to focusing on core parameters such as resolution and touch sensitivity, its physical strength and durability cannot be ignored. As the original factory of touch screens, Xinlilai Optoelectronics will analyze how chemical strengthened technology has become a "required course" for high-quality capacitive touch screens from practical applications today.
 

In these harsh or high-frequency environments, the fragility of an unreinforced ordinary glass screen is evident. And chemical tempering treatment is the core technology that endows glass screens with the "strong and resilient vitality" to cope with these challenges.
 

The core value of chemical strengthened of  PCAP touch screen is reflected in:
 

Improving surface hardness: The Mohs hardness of glass can be increased to 6-7 or even higher (depending on the glass raw material and process), effectively resisting scratches from hard objects, maintaining smooth and unobstructed touch areas, and avoiding scratches that affect display and touch effects.
 

Enhanced impact resistance: When the screen is subjected to external impact, the dense compressive stress layer on the surface can effectively absorb and disperse the impact energy, significantly reducing the probability of overall glass fragmentation. Even if it breaks, the fragments produced by chemically tempered glass are usually smaller and have blunter edges, which can reduce the risk of secondary harm to the human body.
 

Improve bending strength: The screen may experience bending stress during installation or use. Chemical strengthened can significantly enhance the bending resistance of glass, preventing internal circuit damage or functional failure caused by deformation.
 

Strong adaptability: Chemical strengthened has relatively small limitations on glass shape (such as irregular cutting) and thickness (which can be as thin as 0.4mm or even lower), and can flexibly meet the design needs of various customized touch screens.
 

Xinlilai Touch is well aware that the failure of a touch screen may affect the operation of the entire device and user trust. Therefore, we consider chemical tempering as a key part of quality assurance, ensuring that every shipped capacitive touch screen undergoes carefully optimized chemical tempering treatment, laying a reliable and durable solid foundation for your products.
