Features
SITO PCAP product has excellent performance and is suitable for high-end market applications
It also has greatest advantages such as:
- High reliability: As ITO single-sided design, circuits and conductive areas are not exposed on the contrary, they are completely covered and protected between the cover glass.
- Narrow bezel Design: It can achieve the design of narrow bezel, and also with better stability
With good optical performance
AG, AR, AF, or AB coating is available for customized requirement
Multi-touch Interaction
It enables input through multiple touch points, lines and gestures.
High Sensitivity
High Transmittance
Exceed 90%
High Durability
Surface Hardness > 6H
Operating Principle & Structure
The SITO PCAP touch panel is based on the concept of capacitive touch panel. With two adding sets of transparent wires (X, Y) and driving lines that are in different layers, a capacitor node will be formed at the intersection due to they are perpendicular to each other. When the current passes through one of the wires, the other wire and the electronic circuit will connect while the change of the capacitance value is detected. During operation, the controller sequentially supplies current to the drive lines in different layers, so a specific electric field will form between each node and the wire. When a finger or touch medium approaches, the controller can quickly detect the change in capacitance between the node and the wire, and then confirm the position of the touch. Since the transparent wire forms a three-dimensional electric field on the panel that is different from the surface capacitance, the touch can still be operated without actual contact, so we can say, PCAP technology is with the Z-axis resolution capability.

Customized Enhanced Product (Optional)
To achieve the high efficiency of touch panel, our DITO PCAP product is also able to adopt with the following enhanced technology.
EMI Shielding
To meet high-end market needs, such as military standard applications, we can provide professional EMI shielding solutions.
UV Resistant Design
For outdoor application requirements, long-term exposure to the UV environment may cause potential damage to the surface or the coating of the touch panel, which might affect the appearance and the function of it. UV-resistant design can effectively reduce the issue caused by UV exposure.
Vandal Proof Design
To meet safety regulation requirements, products with vandal proof design are provided. The glass substrate of the touch panel must meet the vandal proof specification when it is broken. Ensuring that the fragments will not splash out and injure people when the glass is cracked.
According to some specific optical application, we can use these solutions to achieve clear vision, low reflections, and high penetration.
