Resistive touch screen has already been widely adapted in in various touch-based products. Depending on different design and detection principles, resistive technology can be categorized into four-wire (4w) and five-wire (5w) products.
(1). 4W Principle Design:
With top and bottom surfaces as X-axis and Y-axis electric fields, two conductive wires are added to the surroundings of the two axis respectively. Setting fixed voltage on either ends forms an evenly distributed electric field.
(2). 5W Principle Design:
X-axis and Y-axis are controlled by bottom electrodes. Top surface electrodes are merely used as conductors for the two axis for the sake of detecting voltages. Having such function gives the 5W design a superior consistency and reliability over that of the 4W design.
