Action principle and product structure
DITO projection capacitive touch screen is basically based on the concept of capacitive touch screen, consisting of two sets of transparent axes (X, Y) with different planes and perpendicular to each other, and surrounding printed circuits. Due to the X and Y structures on different surfaces, a capacitive node is formed at their intersection. When current passes through one of the wires through the driving line, the other layer of wires and the electronic circuit that detects changes in capacitance value are connected. During operation, the controller sequentially supplies power to the drive lines of different layers, thus forming a specific electric field between each node and the wire. When fingers or touch media approach, the controller quickly measures the change in capacitance value between the node and the wire, thereby confirming the position of the touch. Due to the three-dimensional electric field formed by transparent wires on the touch screen body, which is different from the surface capacitance, touch can still occur without actual contact; In other words, projection capacitive touch application technology with Z-axis resolution capability.
