To get an exact coordinate, the results from several row/column intersections are read and the counts used to triangulate the exact touch location. so dass kapazitive Platten, Gitterstrukturen fr resistive Touch-Sensoren und. Projected capacitive touch screens are “scanned”, meaning most of these touch screens are made up of a matrix of rows and columns that are “read” one by one to get a reading or count. The invention relates to a multi-touch screen according to the preamble of. PSoC Automotive Multitouch touchscreen controllers leverage the industry's broadest capacitive touch IP portfolio to deliver a new standard for performance to automotive touchscreens. If another conductive object, in this case, a finger, bridges the gap, the charge field is interrupted and detected by the microcontroller. With displays becoming noisier and devices being used in harsher conditions, providing high-touch performance demands a tougher touchscreen controller. Mutual capacitance is now the more common projected capacitive approach and makes use of the fact that most conductive objects are able to hold a charge if they are very close together. The most common design incorporates the simple concept shown below. All projected capacitive touch screen designs have two key features in common – the sensing mechanism (ITO layer) that lies behind the touch surface and the use of no moving parts. Capacitive multi-touch display Can be used in portrait or landscape mode ARM Cortex A9 800 MHz microprocessor 1 or 2 Ethernet interfaces Optional SmartWire. In the short time since the introduction of projected capacitive touch screens in the iPhone, a multitude of construction methods have been developed.
