Did you know that touch panel technology was invented in the 60s?

That's right. Long before your precious smartphone entered the market in the late 00s, touch panels had already been an established technology for nearly 4 decades. 

Despite the panels' simplicity of use, the underlying technology is more complex than it appears, with 4 different touch panel types in existence. 

Before we get to that, let's back up.

It's quite possible that you're not clear on exactly what a touch panel is, what the touch panel types are, or how they're applied in your daily life, beyond that of your smartphone. For that and more, we're here to help. 

What Are Touch Panels?

Quite simply, touch panels, which are also known as touchscreens or touch monitors, are tools that allow people to operate computers through direct touch. More specifically, via the use of internal sensors, a user's touch is detected, then translated, into an instructional command that parlays into visible function. 

The Different Touch Panel Types

Delving deeper into the technical side of things, touch panels are not as cut-and-dry as they may seem. In fact, the way they sense and react to touch can widely differ based on their inherent designs. As such, there are 4 touch panel types in regular use ' Resistive, Optical Imaging, Projected Capacitive, and Infrared. Below, we'll dig into their specifics, which include their advantages, disadvantages, and real-life product applications. 

1. Resistive Touch

Resistive touch panels are cost-effective variants that detect commands by way of pressure placed on the screen. This pressure sensitivity is generally limited to single-point touch, with a 20-inch maximum screen, which is fine for many usage cases. These range from styluses to fingertips. As a result, if used correctly, resistive touch panels will remain functional even if a water drop has landed on the screen.

As a result of this versatility, however, many will find that resistive touch panels are less durable than their competitors. Moreover, with its reliance on single-point touch, this touch panel type is not actually capable of multi-touch functionality. Regardless, resistive touch panels are often found in grocery stores, where stylus-based signatures are typically required after credit card purchases.

2. Infrared Touch

Some like it hot and some don't. Infrared touch panels definitely fall into the latter category. By setting up a grid of infrared beams across the panel, which may be up to 150-inches, touch is detected by way of this panel's disruption.

Although infrared touch panels are durable and support multi-touch functionality, it does possess one potential drawback. Depending on where you sit, literally.

Despite infrared implying heat, infrared touch panels actually perform rather poorly in it, particularly in direct sunlight. In those circumstances, the infrared light beams can be disrupted by the sun's rays, as opposed to your fingers. As such, be sure to place your infrared touch panel device in an appropriately dark location.

3. Optical Imaging Touch

Light, and the disruption thereof, is not just a great way to produce a shadow, but also to design a touch panel type. To take advantage of this principle, optical imaging touch panels are designed to sense touch through infrared cameras and the disruption of light strips. This can be achieved through any input you want, across its 100-inch maximum size, from gloves to bare hands, and beyond.

All in all, optical imaging touch panels are just about the most versatile option the touch-based world can offer. From durability to multi-touch, and universal input prospects, the possibilities may truly be endless. Although its only disadvantage may be its non-compact design, common applications of optical imaging touch panels include certain varieties of interactive whiteboards.

4. Projected Capacitive Touch

If you identify with the phrase, 'go with what you know', then projected capacitive touch panels are the touch panel type for you. For now, you can guess where you know it from.

By way of their electrical-based touch detection, Projected Capacitive touch panels are known for their high precision and high-speed response times. What's more is that they possess multi-touch functionality and can be used within small, compact, yet expensive, devices. Due to their underlying technology, it has proven challenging to scale up to larger sizes. Figured it out yet?

Assuming you haven't, or would like to enjoy the gratified feeling associated with being right, allow us to reveal where you interact with projected capacitive touch panels on a daily basis ' Smart Phones! What's more is that they're not alone, with tablet computers and GPS devices also utilizing projected capacitive touch screens.

Touch Panel Types in the Professional World

It would be a mistake to assume that the applications of all these touch panel types are limited to that of consumer-level devices, or even those that have been previously mentioned. Really, these touch panel types can be found throughout everyday life and in a variety of industries.

What's more is that in many of these industries, these touch panel types are used less to market products to consumers, and more to sell solutions to businesses. Whether it be in regards to finance, manufacturing, retail, medicine, or education, there is always a need for touch-based solutions. In conjunction with the so-called 'Internet-of-things', these touch-based solutions play a key role in practices related to industry 4.0.

In practice, these solutions largely offer a form of personnel management. In hospitals, stores, or banks, for instance, these touch panel types can be used to answer basic questions, provide product information, or offer directions, based on the user's needs. When it comes to manufacturing, on the other hand, these solutions enable employee management in the possible form of workplace allocation or attendance tracking.

At the end of the day, touch panels are here to stay. In the four decades since their inception, the level of adoption this technology has experienced is remarkable. They transform how we teach in classrooms and collaborate with colleagues. 

Although you may not have been clear on the specific details of each touch panel type, we hope that you are now. This knowledge will absolutely serve you well, particularly if you're interested in ViewSonic's selection of touch-based solutions.

With the growth of smart devices, the application of touchscreens is getting closer and closer to our life. Various electronic devices, vehicle tools, daily entertainment equipment, shopping navigation equipment, etc., and the LCD touchscreen has already been integrated into our daily life. When we meet various touch technologies and choose a device with a touchscreen, many questions often arise. What are the advantages of touch displays, and how to choose a better one? Today I will show you a brief introduction to 5 common types of touch screens, as well as their advantages and disadvantages.

According to the touch principle, touch screens can be divided into five basic types: capacitive touchscreens, resistive touchscreens, infrared technology touchscreens, surface acoustic wave technology touchscreens, and low electromagnetic guidance touchscreens. In fact, there are four types of touch screens that we often come into contact with at present, they are resistive touch, capacitive touch, infrared and surface acoustic wave touch. We mainly introduce the differences between these 4 types of touch displays.

1: Capacitive Touchscreen

The technology of the capacitive touch is inseparable from the human body. It needs the mutual induction of the human body current and the ITO conductive layer to work.

First of all, the capacitive touch has 4 layers of glass. The inner surface of the glass and the interlayer are each coated with a layer of ITO. The outermost layer is a protective layer of silica glass. The interlayer ITO coating is used as the working surface, and the electrodes are respectively drawn out from the four corners. when there is a touch with the human body, the finger and the working surface form a current, and the current flows out from the electrodes on the four corners of the touch screen, and the electrodes can sense the change of the surface charge and then determine the coordinates of the touch point. Capacitive touchscreens require only touch, not pressure.

Pros of Capacitive Touchscreen

1. The capacitive touch has fewer corrections working after production, which can improve work efficiency and reduce the generation of defective products;

2. Long working life;

3. Light transmittance and clarity are better than the resistive touchscreen;

4. Capacitive touch is easy to design on large-size LCD display and the cost is relatively low;

5. Can support multi-touch technology.

Cons of Capacitive Touchscreens

1. When a large-area palm or a handheld conductor is close to the capacitive touch display, even if there is no touch on the screen panel, it can also cause a touch action on the display panel;

2. For objects such as wearing gloves or holding an insulating object, the touch does not work, because the insulation medium is added, and the touch point will move;

2. The light transmittance of the capacitive touch screen is not uniform, and there is a problem with color distortion. Due to the reflection of light between the layers, the image characters will be blurred;

4. When the ambient temperature and humidity change, it will cause the capacitive touch point to move and the touch will be inaccurate.

 

2: Resistive Touchscreen

A resistive touchscreen is a type of touchscreen that uses pressure sensing for control.

It uses two layers of ITO (Indium Tin Oxide) plastic film (ITO+Glass) coated with conductive function. The side of adjacent to the film and glass are all coated with ITO coating. When there is no pressure, there is a gap between the two layers of ITO, and the certain gap is in a non-conductive state. When there is pressure, whether it is human finger pressure or object pressure, the two ITO layers will contact to form a current signal, and then convert the corresponding pressure point by detecting the X-axis and Y-axis voltage changes to complete the touch processing of the entire screen mechanism.

Pros of Resistive Touchscreens

1. Mature technology, low cost;

2. Good environmental adaptability, no worry about the influence of dust, water vapor and oil pollution;

3. Good stability, both the human body and objects can be touched;

4. The precision of the resistive touch screen is high; it is easy to design on a large resolution LCD screen;

Cons of Resistive Touchscreens

1. The touchscreen is easily scratched and the makes the touch is unavailable;

2. Poor light transmission, easy to increase battery consumption;

3. When multi-touch is used, due to unbalanced pressure, the tactility is not good, and the touch point will be incorrect;

4. Relatively low touch sensitivity.

3: Infrared  Touchscreen

The infrared touchscreen is easy to install, just add a light spot distance frame on the LCD display panel, no need to coat any IoT. The infrared touch display uses the dense infrared matrix in the X and Y directions to detect and locate the touch point. When the user touches the screen, the touching object will block the two horizontal and vertical infrared rays passing through the position, so as to obtain the position of the touch point to realize the touch. Any touching object can change the infrared rays on the contacts to realize the touch screen operation.

Pros of Infrared Touchscreen

1. The infrared touchscreen is not affected by the current, voltage and static electricity;

2. Low price, easy installation, no need for any controller;

3. Compatible with computers of various grades.

Cons of Infrared Touchscreen

1. Difficult to use on large size LCD screens;

2. Easily disturbed by external light,

3. The infrared touch screen is not waterproof or oil-proof, and any small foreign objects will cause errors and affect its performance.

 

4. Surface Acoustic Wave Touchscreen

The touch screen part surface of acoustic wave touch can be in a flat, spherical or cylindrical glass plate, a piece of glass installed in front of the CRT, LED, LCD or plasma display screen. This glass has been strengthened and specially treated, and it is installed on the surface of the display. Vertical and horizontal ultrasonic senders are installed on the upper left and lower right corners of the glass, and ultrasonic receivers are installed in the upper right and low left corners. when the finger touches the glass surface, the finger absorbs part of the sound wave energy, the controller records this anomaly and calculates the position of the touch point.

Pros Surface Acoustic Wave Touchscreen

1. High clarity and good light transmittance.

2. Highly durable, good scratch resistance and responsive.

3. Not affected by environmental factors such as temperature and humidity, high resolution, and long prolife;

4. High light transmittance, can maintain clear and bright image quality;

Cons of Surface Acoustic Wave Touchscreen

1. Applicable to smaller screens, hard to use on larger screens more than 30 inches;

2. Susceptible to moisture damage, so not suitable for many industrial and commercial applications;

3. Dirty surfaces can cause dark spots on the screen and require regular cleaning
