Did you know that touch panel technology was invented back in the 1960s? That’s right—long before smartphones became the norm, touch panels had already been shaping the way we interact with technology. Despite their simplicity to use, the underlying technology is intricate, with four main types of touch panels leading the way.

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

Touch panels are far more nuanced than they might initially seem. The way they sense and react to touch varies significantly depending on their design and underlying technology. Currently, there are four main types of touch panels in regular use: Resistive, Infrared, Optical Imaging, and Projected Capacitive. Below, we’ll explore their unique features, advantages, limitations, and common applications.

1. Resistive Touch

Resistive touch panels are among the most cost-effective options. They operate by detecting pressure applied to the screen, which makes them compatible with various input methods, such as fingertips, styluses, or even gloved hands. These panels consist of two thin, flexible layers separated by a gap. When pressure is applied, the layers make contact, registering the touch.

Advantages:

Affordable and widely accessible.

Functional even with non-conductive inputs (e.g., gloves, styluses).

Unaffected by water on the surface, making them reliable in wet environments.

Disadvantages:

Limited to single-touch functionality.

Less durable compared to other technologies due to wear over time.

Typically capped at smaller sizes (around 20 inches).

Applications:
Resistive touch panels are commonly used in point-of-sale systems (like grocery store checkout screens) and industrial equipment, where cost-effectiveness and simplicity are key.

2. Infrared Touch

Infrared touch panels use an invisible grid of infrared beams projected across the screen. When an object interrupts the beams, the panel detects the touch. This technology allows for larger screen sizes, often up to 150 inches.

Advantages:

Highly durable and resistant to wear and tear.

Supports multi-touch functionality.

Works with any input, such as fingers, gloves, or styluses.

Disadvantages:

Poor performance in direct sunlight or high-temperature environments, as infrared beams can be disrupted by external light sources.

Applications:
Infrared touch panels are often used in interactive displays and large-format touchscreens for conference rooms, education, and digital signage.

3. Optical Imaging Touch

Optical imaging touch panels detect touch using infrared cameras and light strips that sense disruptions in light patterns. This technology supports large touchscreens (up to 100 inches) and allows for input from virtually anything, including gloves or objects.

Advantages:

Versatile input options.

Durable and supports multi-touch functionality.

Ideal for large-scale applications.

Disadvantages:

Bulkier design compared to other touch panel types.

Applications:
Optical imaging touch panels are widely used in interactive whiteboards and digital kiosks, where flexibility and durability are critical.

4. Projected Capacitive Touch

Projected capacitive (PCAP) touch panels are well-known for their precision and responsiveness. They work by detecting changes in an electrical field when conductive objects (like fingers) touch the surface. These panels are compact and widely recognized for their multi-touch capabilities.

Advantages:

High-speed response and precision.

Supports multi-touch gestures.

Durable surface, resistant to scratches and wear.

Disadvantages:

More expensive than other options.

Limited scalability for larger screens due to increased complexity and cost.

Applications:
Projected capacitive touch panels are most commonly found in smartphones, tablets, and GPS devices, where compact, high-performance touchscreens are essential.

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.

Final Thoughts

Touch panel technology has made remarkable strides since its invention in the 1960s. From budget-friendly resistive panels to the cutting-edge precision of projected capacitive screens, each type fulfills specific purposes across a broad range of industries and applications. Whether in retail, education, corporate settings, or personal workspaces, touch panels have become an essential part of our daily lives.
