Matrix Touchscreens
Matrix touchscreens offer flexibility and economy in applications where mouse-emulation is not required, or when replacement of mechanical buttons and membrane switches with software-enabled buttons is desirable. Matrix technology is a cost-effective touchscreen for use in security systems, home control systems, appliance and automotive controls, and industrial equipment.
Matrix touchscreens are constructed of two conductive layers, a polyester top sheet and glass bottom layer, each etched to create a grid of rows and columns. Each layer carries four transparent conductive strips, connected by electrodes to four wires per layer, which in turn are connected to controller electronics. Touch compresses the layers, causing current to flow through the rows and columns where the touch occurs.
