A Projected Capacitive Touch (PCT; also PCAP) technology consists of an insulator such as glass, which is coated with a transparent conductor, like ITO (indium tin oxide). The user’s finger conducts electricity, so touching the surface of the screen results in a distortion of the screen’s electrostatic field; that distortion is measurable as a change in capacitance.

Infrared (IR) and Projected Capacitive (PCAP) are the two most common types of touch screen technologies. Although you may not be able to tell the difference when using an interactive touch screen unless you know how to identify which is which, they are quite different in structure and design. Below we’ll break down the difference between the two to give you better idea of why one might be better than the other for whatever purpose you may be buying or renting your touch systems for.

PCAP touch screen software is typically used in smart phones and tablets, but can also be used for much larger screens. It works through the use of a conductive grid that recognizes changes in its electromagnetic field by the touch of your finger. Projected capacitive touch screen technology does not require a bezel. They detect only fingers or styluses. PCAP displays very accurate, and capable of up to 60 touch points.

IR touch technology involves an embedded overlay of infrared beams from top to bottom and side to side around the device’s bezel. When the invisible plane provided by the beams in broken by any object, the device registers a touch point. With up to 40 simultaneous touch points, IR touch screen displays are a bit less accurate than PCAP displays. That said, Infrared displays are still quite accurate enough to be used in a wide variety of settings. But when used outdoors on a bright and sunny day, the sunlight can sometimes interfere with the overlay’s touch reception.

PCAP technology is a newer variation of the commonly used capacitive touch sensors. Combining the same grid-patterned electrode style of traditional capacitive sensors results in a high-resolution, fast, and intuitively responsive touch screen that can be used with even laminated glass. Pro Display offers a range of PCAP touch technologies including ourInteractive Touch Foil, which transforms any glass or acrylic surface into a touch screen (and can even be used with gloves), great for use in store window displays these foils are a great example of how projected capacitive touch screen technology can be used. PCAP solutions are available in single, dual and multi touch options up to 40 touch points.

Some of our most popular PCAP technologies include ourInteractive Touch Table, ideal for meeting rooms and collaborative workspaces and ourInteractive Projection Foils, which incorporate our range of high gain / high contrast rear projection films.

Now that you know a bit more about PCAP, infrared andgesture touch technologies, you might be wondering which one is best suited to your application and why. Let’s look into the pros and cons of each technology, as well as outlining which are best for different use-cases.

PCAP screens share many of the same advantages and disadvantages of capacitive touch screens, with a few key additional benefits and drawbacks. PCAP screens possess greater scratch resistance than infrared touch screens, usually featuring a glass or acrylic overlay to protect the display underneath.

PCAP screens allow for multi-touch use, allowing users to manipulate their screen applications using up to 40 touch points instead of the single touch point offered by standard capacitive touch screens, while better maintaining functionality in the presence of dirt, dust, grease and water.

If you do use a PCAP screen, however, you’ll be unable to operate the screen with solid objects like a plastic card or pen—only tapping with thin cotton/latex gloves or an exposed finger will create the desired response from the device. The screens are also highly sensitive to electro-magnetic interference and radio frequency interference. Therefore, if you use a PCAP screen around these waves then this will likely affect the usability and performance of the screen.

Infrared, the most standout technology when compared to PCAP and capacitive touch screens, comes with its own unique advantages. IR touch relies on the sensors located around the inside of the screen’s bezels to register a touch and effectively have an unlimited “touch life” since wear and tear from physically using the device will not degrade the screen’s responsiveness. However, due to touch frames sitting on top of the display itself, the screen surface is still susceptible to wear and tear. This can be solved by one of two ways, one option is to set the touch frame away from the screen itself, to allow the sensors to register the touch before the user makes contact with the screen. Alternatively, our touch frames can be manufactured with a glass or acrylic overlay to protect the display, ideal for softer screens like LCD’s and monitors.

Whilst the body tracking foundations of this technology could potentially change the way we use touch screens entirely, it still has its drawbacks. Whilst technologies like Infrared and PCAP offer solutions with up to 40 touch points, the Azure Kinect is limited to the amount of bodies it can track based on the field of view, making it unsuitable for use in high traffic areas.

Projected capacitive (PCAP) touch screens are the latest iteration of a long history of touch sensor technologies dating back decades. The usage of PCAP touch screens has risen in conjunction with the proliferation of consumer electronics, medical device advancements and more sophisticated automotive applications, creating breakthrough specializations and use cases.

A PCAP screen’s conductive grid picks up changes in capacitance, which is the mechanism behind registering a touch. Paired with different bonding techniques, surface treatments and touch controller tunings, the ability to customize PCAP touch screens has led to endless permutations of highly successful touch display products.

PCAP screens use two layers of electrodes (X and Y) that form a capacitive electromagnetic field around them. When a finger, stylus or other conductive object hovers or touches the screen, it results in an electric charge that enables the processing system to identify, register and respond to the signal. A finger, for example, penetrates the electromagnetic field, creating a change in capacitance.

PCAP sensors have almost completely replaced resistive touch sensors over the years due to their numerous advantages. They can support multi-touch, gestures and 3D proximity sensing, and provide superior reliability and durability. This makes them ideal for automotive, consumer, medical, and industrial applications that require more functionality than buttons and single points of contact can offer.

PCAP technology is highly customizable and can be designed to individual customer needs. Engineers can tune PCAP touch sensors for application-specific sensitivity and accuracy, using custom touch controller algorithms. These capabilities make PCAP touch sensors an ideal solution for applications with rigorous requirements.

A 2-layer glass touch panel stack has X and Y electrodes patterned on two different glass layers, bonded together using OCA. The Y electrodes are patterned on the top glass layer, and the X electrodes are patterned on the bottom glass layer. This stack is customizable with additional protective cover lens optically bonded to the sensor, with optional back printing. This was the initial structure used for PCAP stack-ups.

One final point of differentiation among PCAP touch panel designs is how and where the chip is mounted. Two methods can be used:COF (Chip-on-flex:) The controller and supporting electronics are on a flexible substrate. This is the primary chip integration method used for touch sensors due to it being slim and flexible, but may not be possible for sensors larger than 15 inches.

Projiziert kapazitive Touchscreens werden meist kurz PCAP (von projected capacitive) Touchscreens genannt. Sie sind robust, können problemlos auch mit dicken Schutzgläsern versehen werden und bieten eine Multi-Touch Funktion für bis zu 10 Finger, die Gestensteuerung möglich macht.

PCAP Touchscreens sind mit einem Netz aus Elektroden ausgestattet (Metal Mesh, Silver Nanowire, ITO), die ein elektromagnetisches Feld aufbauen (projizieren), das auch durch ein Schutzglas reicht. Wenn sich dieses Feld an einer Stelle durch Berührung mit einem Finger oder einem Eingabestift verändert, wird die Touch Position berechnet und an den Controller weitergeleitet. Drag & Drop, Zoomen, Drehen oder Blättern duch Gestensteuerung sind ebenfalls möglich.

Durch die Glasoberfläche sind die PCAP Touchscreens besonders kratzfest und lassen sich mit allen Reinigungsmitteln säubern - ein wichtiger Vorteil in hygienisch sensiblen Bereichen.

Mit speziellen Schutzgläsern werden die Touchscreens vandalensicher und lassen sich in öffentlichen Bereichen einsetzen. Die Anzahl der Touchpunkte kann allerdings je nach Stärke des verwendeten Schutzglases variieren. PCAP Touchscreens eignen sich perfekt für moderne True Flat Designs, wie bei Smartphones oder Tablet PCs und sorgen so für ein ansprechendes Gerätedesign. Gerne bieten wir Ihnen die Touchscreens auch optisch gebondet als Einheit mit einem Schutzglas und/oder einem TFT Display an.

Projected capacitive (PCAP) touch technology has just recently been scaled up for use in large format applications like the TSItouch interface. PCAP touch has been implemented in popular handheld devices such as smartphones and tablets for years. In a PCAP system, a touch point is detected when a finger or stylus comes in contact with the surface, signaling a change in the system’s electromagnetic field and capacitance.

This touch triggered change is then pin-pointed and converted to locations on an X/Y electronic grid. The system uses this point on the X/Y grid to determine the placement of the touch. The TSItouch PCAP interface features a seamless at front bezel design, allowing the monitor to be easily be wiped clean, eliminating having to worry about dust and dirt collection.

Projective Capacitive touchscreen (P-CAP, Pro-Cap or PCAP touch screens) sensors function by maintaining a standing electrical charge across the sensor that extends through a contact surface, where changes in the electrical charge caused by the proximity of other capacitive bodies (such as touch stylus, fingers etc.) can be detected by a touch controller.

Due to the glass surface, the PCAP touch screens are particularly scratch-resistant and can be cleaned with all cleaning agents - an important advantage in hygienically sensitive areas.

This PCAP touchscreen technology is generally now used as the preferred method of user interface for modern tablets and smart phones because the touch sensor is on the rear it allows for a true flat edge to edge cover glass given this up to date feel for the touchscreen. We can produce Capacitive touchscreens from as small as 1.77” diagonal to 86”
