Low Resistance USB 86" Projected Capacitive Touch Screen
86" PCAP Touch Panel with SP-ITO film with Low Resistance High Stability
Introduction of SP-ITO Touch Screen
SP- ITO is a thin film material that can conduct electricity and behave as optically transparent. It is an extremely important optoelectronic material. It is widely used in P- cap Touch Panel, Smart Touch Window, EMI touhch products etc.
SP-ITO flexible nano transparent conductive material uses magnetron sputtering process, which effectively improves the stability and cost advantage of the product. It is completely different from ITO, metal mesh, and nano silver wire, and has a greater cost-effective advantage.

Advantages of SP-ITO Touch Screen
1. Compared with other materials, SP-ITO has good electrical conductivity, good light transmission, excellent flexibility, high cost performance, good stability, and no moiré issue.
2. Realize process simplification: The new material application process can directly simplify more
than half of the traditional process, and the yield rate is greatly improved.
3. Cost down:
a. The application of new materials can eliminate all silver paste manufacturing processes and reduce the production cost of products.
b. The application of new materials can reduce the investment of production
personnel by more than half compared with the traditional production process.
