HOW DOES PROJECTED CAPACITIVE TOUCH SENSOR TECHNOLOGY WORK?
Projected capacitive touch sensor technology works by utilizing a grid of micro-fine wires that are bonded onto a glass or laminated film surface.
This type of touch technology is commonly used in modern touchscreens and offers precise and responsive touch input.
The touch sensor grid consists of two layers of conductive material, typically indium tin oxide (ITO), arranged in a matrix pattern.
These layers are separated by a dielectric material, forming a capacitor at each intersection point of the grid.
When the user touches the surface of the touchscreen, their finger or a conductive stylus alters the capacitance at that specific point, creating a measurable change in electrical charge.
To detect and locate touches accurately, the touch controller continuously scans the entire grid, measuring the capacitance at each intersection point.
By analyzing the changes in capacitance, the touch controller can determine the position and movement of the touch input.
The projected capacitive touch technology offers several advantages.
It allows for multi-touch functionality, meaning it can detect and track multiple touch points simultaneously.
This enables gestures like pinch-to-zoom, swipe, and rotate, enhancing the user's interaction with the touchscreen.
Additionally, projected capacitive touch sensors offer high clarity and transparency, making them ideal for applications where image quality and visual aesthetics are crucial.
The use of glass or laminated film as the touch surface provides durability and scratch resistance, ensuring long-lasting performance.
