Capacitive sensing in touch screens has been around since the 1970’s, but with the recent explosion in popularity of the smart phone, projected capacitive sensors (PCAP) have come to the forefront of touch screen technology. PCT technology is a capacitive technology which permits more accurate and flexible operation, projection of the touch field through additional layers of material plus offers full multi-touch …
Dr Pan: When a finger comes close to the surface of projected capacitive touch screen, it will absorb some electricity from the near insulated ITO grids and the electrostatic capacitance will change according to distance from the finger.
30/9/2019· Projected Capacitive Touchscreens Explained Also known as PCT or PCAP, projected capacitive is a form of touchscreen technology that’s used in smartphones, tablets, human machine interfaces (HMIs) and dozens of other touchscreen devices. It’s essentially the same as surface capacitive technology but with a few added upgrades.
A projected capacitive is very similar to a surface capacitive, but has some added features that make the touch technology a bit more unique. A projected capacitive touch has the ability to enable multi-touch that can be applicable to certain touch appliions.
Projected capacitive technologies detect touch by measuring the capacitance at each addressable electrode. When a finger or a conductive stylus approaches an electrode, it disturbs the electromagnetic field and alters the capacitance.
Projected Capacitive Touch Panel Technology Projected capacitive touch panels are also built with two parallel layers of ITO, but, unlike resistive touch panels, the ITO layers in a projected capacitive touch panel are sealed between two sheets of glass by an optically clear adhesive. There is no air gap between layers like a resistive touch panel.

Projected Capacitive Touch Screen Projected Capacitive (P-Cap) is similar to Surface Capacitive, but it offers two primary advantages. First, in addition to a bare finger, it can also be activated with surgical gloves or thin cotton gloves. Secondly, P-Cap enables multi …
The PCAP or Projected Capacitive touch screen technology provides the accessible multi-touch experience through tablets, smartphones to operate through extremely light touch using an extremely tough glass surface.
Projective Capacitive Touchscreen (PCAP/PCT) The PCAP touch screen technology is the newest generation of capacitive touchscreens, a further development of the surface capacitive touch. PCAP touch screens are usually used for consumer products like smartphones or tablets.
Projected Capacitive Touch Screen. Projected Capacitive (P-Cap) is similar to Surface Capacitive, but it offers two primary advantages. First, in addition to a bare finger, it can also be activated with surgical gloves or thin cotton gloves. Secondly, P-Cap enables multi …
The technology, called projected capacitive touch, is the first choice for most touch products now in development. The technology is not just Apple-trendy but incorporates the best of the competing touch technologies. There are several benefits to using projected capacitive technology but the four most important are: 1. Long Life 2. Excellent
Touch Foil (Flexible Film) Projected Capacitive Touch (40 points) - incorporates the patented Projected Capacitive Technology (PCT). It is designed to be mounted to the rear surface of a rigid transparent substrate (such as glass

Projected Capacitive Touch Screen Technology and Borders With the advent and ever-increasing popularity of smartphones and tablet computers, projected capacitive (PCAP) touch sensors are becoming more prevalent every day. This prevalence is leading more and more product development teams to look at including touch features in their new designs.
Projected capacitive requires an advanced technology to measure electrostatic capacitance and achieve precise loional information from it. Unlike resistive technology, it does not work simply by connecting a touch screen with a controller sourced from somewhere. A projected capacitive touch screen and controller need to be designed together.
The clear advantages of this touchscreen quickly transformed the industry – the use of capacitive screens exploded and by 2013, only 3% of touchscreens shipped were Resistive and 90% were Projected Capacitive Screens. As the cost of capacitive screens decreases and quality is continuing to progress rapidly, this technology continues to
Projected capacitive touch screen monitors provide great clarity with a durable touch screen that has excellent resistance to surface contaminants such as dust, oil, grease and water droplets, with high scratch resistance.
Antibacterial surface protection for displays is an innovative and effective solution that users can rely on and trust. It''s the next big step in smart display solutions.
