Back side of a Multitouch Globe, based on projected capacitive touch (PCT) technology Schema of projected-capacitive touchscreen. Projected capacitive touch (PCT; also PCAP) technology is a variant of capacitive touch technology but where sensitivity to touch, accuracy, resolution and speed of touch have been greatly improved by the use of a ...

Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens).
[7] [8] [2] [9] [10] In 1973 Beck and Stumpe published a CERN report, outlining the concept for a prototype touchscreen as well as a multi-function computer-configurable knob. [11] [12] On the left, x-y multi touch capacitance screen prototype developed at CERN in 1977; [13] [14] on the right, self capacitance screen developed at CERN in 1972. [15]
Resistive touchscreen technology works well with almost any stylus-like object, and can also be operated with gloved fingers and bare fingers alike. In some circumstances, this is more desirable than a capacitive touchscreen, which needs a capacitive pointer, such as a bare finger (though some capacitive sensors can detect gloves and some gloves can work with all capacitive screens).
One Glass Solution [1] (OGS) is a touchscreen technology which reduces the thickness of a display by removing one of the layers of glass from the traditional capacitive touchscreen stack. The basic idea is to replace the touch module glass with a thin layer of insulating material. In general, there are two ways to achieve this.
Capacitive styluses work by distorting the screen’s electrostatic field. [9] Screens that receive input from a capacitive stylus (as well as human fingers) can't register pressure applied by the pen; tilting of the pen; and can't distinguish between a capacitive stylus, your finger, or a resting palm as input - it will register all of these ...
