Capacitive Touch Panel Technology
Capacitive Touch Panels are an all-glass touch panels with a transparent metallic conductive coating. An electrode pattern printed along the edges which distributes a low voltage field over the conductive layer.
When a finger touches the panel and draws a minute amount of current to the point of contact, creating a voltage drop. The current flow from each corner is proportional to the distance to the touch point.
The X/Y location of the point of contact is calculated by the controller and transmitted to the computer.
Capacitive Touch Panel Benefits:
- Excellent optical properties with a transmittance greater than 90%.
- Tempered glass with a scratch hardness of 6H.
- FPC tail offers low resistance, flexibility and robustness.
- High sensitivity, immediate response at the slightest touch.
- Touch panels are extremely durable. Withstanding water, dust, harsh chemicals and grease.
Advantages:
- Accurate Control: Less than +/-1.5% linearity deviation and controller with excellent speed.
- FPC Tail Technology: FPC tail has low resistance and is very flexible and robust.
- Durability: Our Capacitive touch screen withstand contaminants such as grease, dirt, water, running liquid, harsh chemicals.
- Performance: A transparent protective hard-coating minimizes reflection and maximizes light transmission. Hardened glass offers excellent scratch resistance and durability.
