29 Projected Capacitive Technology The most recent addition to projected capacitive technology is Multi-TouchMulti-Touch Projected Capacitive Sensor
30 Projected Capacitive Technology There are Two Projected Capacitive Sensing Methods:Self-Capacitance (Rarely Used Now)Mutual Capacitance (Most Common)Mutual – How it WorksContains grid of sensing and driving lines to determine touch location.Makes use of the fact that most conductive objects are able to hold a charge if they are very close together. If another conductive object, like a finger, bridges the gap, the charge field is interrupted and detected by the microcontroller, resulting in a touch.Mutual Capacitance , compared to self-capacitance makes it easier to identify the specific touch points.
31 Projected Capacitive Technology ScanningProjected Capacitive touch screens are “scanned”, meaning they are made up of a matrix of rows and columns that are “read” one by one to get a reading or count.How it WorksTo get an exact coordinate, the results from several row/column intersections are read and the counts are used to triangulate the exact touch location.BenefitsThe touch points are extremely precise and the resolution is usually 1024 by 1024 (ten bit).Scanning also has an advantage of being free of coordinate drift.Without the issue of coordinate drift, projected capacitive touch screens do not have to be calibrated by the end-user.
