A Touch Panel is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touching the display of the device with a finger or hand. Touch Panels can also sense other passive objects, such as a stylus.
FEMA Electronics offers touch panels in these standard sizes: 2.8", 3.5", 4.3", 5.6", 5.7", 6.4", 7.0", 8", 10.1", 10.4". We also produce them in custom sizes per customer specification.

View Resistive Touch Panel Specs
Resistive touch panels are composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. When contact is made to the surface of the touchpanel, the two sheets are pressed together. On these two sheets there are horizontal and vertical lines that when pushed together, register the precise location of the touch. Because the touchpanel senses input from contact with nearly any object (finger, stylus/pen, palm) resistive touch panels are a type of "passive" technology.

View Capacitive Touch Panel Specs
A capacitive touch panel is one which consists of an insulator such as glass, coated with a transparent conductor such as indium tin oxide (ITO). As the human body is also a conductor, touching the surface of the panel results in a distortion of the panel's electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing.
