55~86Inch GFF PCAP Touch Panel With SP-ITO Film With High Transmittance Low Resistance
This capacitive touch screen is GFF structure, it is using SP- ITO film for touch sensor, which 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 Window,EMI etc.
Compared with other materials, SP-ITO has good electrical conductivity, good light transmission, excellent flexibility, high cost performance, good stability, can make super-narrow bezel, flexible touch screen and no moiré issue

Capacitive Touch Panel:
Capacitive Touch Panel is to use the working current of induction of human body.The operational principle of the projected capacitive touch panel: There are two layers of the ITO layer under the surface of glass. This ITO layer respectively forms the electric field of X axis and Y axis, which can keep balance by crossing the surface of the class. Once the fingers approach the glass surface, the fingers and the electrode X axis or Y axis will form a new electric field, which can make the local capacitance change. Then the controller will determine the location based on capacitance changes.
Advantages of SP-ITO Touch Screen
1. Provide new solutions for flexible curved touch panel, and super-large touch panel to 86” now.
2. Effectively control optical defects and reduce phase difference.
3. Higher yield and process stability.
4. More suitable for accuracy design.
5. Better curling performance (more than 100,000 bending tests).
6. The silver paste loading process can be omitted for low impedance (patent applied).
7. Low resistance 5Ω~10Ω.
8. High transmittance about 82%~86%.
9. Super-narrow bezel without silver paste.
