Touchscreens grow in popularity as a part of user interface systems and become a critical design decision. Each type of touchscreen, resistive or projected capacitive, offers many advantages. 

Do you want to know how to select the one that provides the optimal user experience from the wide variety of touchscreen options?

1. What Is Touchscreen Technology?

Traditional input devices for computer systems contain keyboards and mice. Touchscreen technology has become widely used to interact with computer systems and mobile devices.

A touchscreen is an electronic visual display that a user controls by touching the screen with fingers. A touchscreen allows more direct interaction with what is displayed than a mouse device. Touchscreens have become very common on smartphones, tablet computers, and other mobile devices. Additionally, standard laptops and desktop computers use touchscreen displays to use both touches and more traditional ways of input.

The first major successful technology was the resistive touchscreen, which uses a panel including two thin, electrically charged layers separated by a narrow space. These two layers touch by pressing the panel, and the location of the connection is recorded as the input. Resistive touchscreens are somewhat cheap and resistant to liquids, but they have relatively poor contrast, and you need to press them down with some pressure. Resistive touchscreens did not become widely used for computer systems but developed as part of other electronic systems. For instance, control panels in factories and the display screens used in restaurants to enter orders are resistive touchscreens.

The second major technology used in touchscreens is the capacitive touchscreen, which uses a layer of insulating material, such as glass, coated with a transparent conductor and touching the screen with your finger changes the screen’s electrostatic field. Several approaches can be used to record the location of the touch. Using a fine grid of capacitors is one of the most common ways to record the electrostatic field’s change. 


2. Multi-Touch Gestures

Touchscreen technology works similar to a computer mouse at a basic level. Instead of moving your pointer with a mouse, press the location with your finger. Multi-touch technology makes it possible to interact with the computer display in many ways. With touchscreen technology, tasks like scrolling up and down a web page, selecting text and drag-and-drop have become quite different. This figure shows several single and multi-touch gestures.


Things To Consider When Choosing A Touchscreen Technology

There are some important things you need to know while choosing a touchscreen, which are given below.

3. What Is The Intended Use Of The Device?

The first step is to precisely define what the device will be used for and which touchscreens are feasible. For instance,

Is the screen intended for an inexpensive toy where durability is not a huge concern?

Will your display be for a military application, subject to harsh conditions? 

Both situations require different durability, functionality, pricing, and input registration screen technologies. The next step is to figure out which functionalities are necessary once you have narrowed down the planned use for the display.


4. Which Touch Features Are Required?

You should know about users’ preferences; for example, will users only need to select single inputs with one finger on your device? 

If Yes, a standard 4-wire resistive touchscreen is perhaps a perfect option for them. A 4-wire resistive touchscreen’s simple construction handles this without adding much cost. However, if users need to zoom, scroll, or activate features with multiple touchpoints, that will narrow the selection to screens with multi-touch functionality, such as a projected capacitive or a resistive multi-touch screen.

5. How Will The Touchscreen Be Activated?

Given how touchscreens register inputs, activating the screen is an important consideration. 

Will the user wear gloves or another object to touch the screen? If so, specific types of touchscreens are necessary to register those inputs. While the sensitivity of a projected capacitive touchscreen can be adjusted to note certain styluses and gloves, the object used must be able to disrupt the capacitive field. A resistive touchscreen is optimal for applications where other input devices can register inputs from nearly any object.


6. What Is The Environment To Use Touchscreen?

Where the touchscreen will activate is another essential factor to consider.

Is it subject to drastic cleaning agents in a medical setting?

Will it be used in an industrial environment to repeat impacts? 

 PCAP technology is ideal if durability is a vital concern, given that damage to the cover glass does not change its ability to register inputs correctly. Resistive screens meet performance requirements for softer environments without adding additional cost.

7. What Is The Price Point?

Resistive touchscreens still tend to be cheaper, as PCAP touchscreens technology becomes more popular and its cost decreases. If you are looking for a touchscreen for a game, toy, or other cheap application, a simple 4-wire resistive touchscreen may add unnecessary cost to the device. However, a projected capacitive screen will be worth the additional cost in the case of a computer, smartphone, or other costly application that requires a high-end look.

8. How Many Actuations Does The Touchscreen Require To Handle?

Different touchscreen constructions are ranked for different numbers of actuations. A 4-wire or 8-wire resistive touchscreen will be optimal for a device that needs to remain accurate only for a few thousand actuations. In contrast, if the device will require significantly more usage, a 5-wire touchscreen is a better choice. However, a projected capacitive screen would be ideal if a display handles millions of actuations, as it can maintain its accuracy over infinite inputs.


9. Final Words

All the above questions are a great start, and this is far from a comprehensive list of variables to consider when deciding on the optimal touchscreen technology. Please schedule a consultation with our experts to discuss your project requirements and custom solutions.

The day-by-day increase in touch screen devices makes people aware of the three main types of touch screens, and a capacitive touch screen is one of them. Capacitive has become the world’s most popular touchscreen technology and commonly used, and it powers everything from smartphones to human-machine interfaces (HMIs), smartwatches, and much more.

1. What Is a Capacitive Touchscreen?

A capacitive touch screen is a capacitive sensor of a conductor and an insulator. Capacitive touchscreen monitors are highly responsive due to their conductive capabilities, even to the slightest touch of your finger. They are double-layered; the top layer is made with durable glass for protection, a strong point of contact, and the inner layer comprises heavy-duty insulation. The human body has conductive properties, so capacitive monitors respond to human contact only, and it automatically registers the exact point of contact as soon as the device detects heat. 

2. How Do Capacitive Touch Screens work?

You should know about answers to a few questions.  

How does an ordinary keyboard work? 

Where each key is an electrical switch is vital to understanding?

How does Capacitive Touch Screen work?

Touchscreens work in different ways; some of them can detect one finger. It becomes too confusing if two different places are touched simultaneously, but others can be with this action. The arrival of touchscreens brought “swear words” like “capacitive screen” or “resistive screen” in our lives that many people cannot distinguish in the end. All the touch screen devices offer a two-dimensional detection process made of two sheets of material. And divide them into separate sheets. Closing an electrical circuit using your fingers makes it very simple to detect human contact accurately, as humans are good drivers of this technology. 


Touchscreens have three vital components: 

  1. a touch sensor,
  2. a touch controller,
  3. a software controller. 

The screen is an input device itself, and the touch input system is completed by combining it with a PC or monitor.

Touch Sensor

A transparent glass panel with a susceptible touch surface is a touch sensor, and different types use another method to detect the input. The sensitive area of the panel covers the display area of the video screen as the touch panel is placed on top of a display screen.

Touch Controller

The touch controller is a PC card linked between the PC and the touch sensor. Usually, it is installed inside the touch screen to integrate the screen. The controller translates the information from the touch monitor that the PC can understand. 

Software Driver

Software driver provides a software update for the PC system to allow the PC and touch screen to work together and determines how the PC operating system would interpret the touch event information sent from the controller. It provides the opportunity to create new applications without specific touch screen programming. Most touch screen drivers emulate the mouse-type driver, enabling the touch screen to work with existing software.

3. How to Choose a Capacitive Touchscreen?

You need to know four main things if you want to buy a capacitive touchscreen. Following a few tips will help you find the perfect and long-lasting capacitive touchscreen.


All capacitive touch monitors require backlighting to express the screen interface to look at the icons and virtual buttons. There are two types of backlighting EL and LED, used in capacitive touchscreens and are energy efficient, but EL uses a little more power than LED backlighting.

  • electroluminescent (EL) backlighting
  • light-emitting diode (LED) backlighting.

Surface or Projected 

Two types of capacitive touchscreen technology include: surface and projected.

Both projected capacitance and surface capacitance are similar technologies, but projected capacitance uses intelligent processing to deliver a higher level of accuracy and detect touch commands more accurately; this is the main difference. 


The resolution offered to the numbers of pixels included in the display and a grid of pixels responsible for producing visible images when illuminated by the backlighting.

The resolution of a capacitive touchscreen display varies, and the display will produce more precise and more detailed images with a high resolution.


When choosing a capacitive touchscreen, you should consider the size. Capacitive touchscreens are available in many sizes. You can order them in a custom size to fulfil the needs of your application. 

4. Benefits of Capacitive Touchscreen Technology

Most manufacturers of touchscreen devices prefer capacitive technology over resistive. So, what makes capacitive the preferred choice?

Requires Less Pressure

Capacitive touchscreens require less pressure to operate because they register touch via the human body’s electrical current. You can generally use a capacitive touchscreen by dragging your finger across the surface. 


The key benefit of capacitive touch screen technology is its strength and durability. Capacitive touchscreens are more durable; it’s essential to choose a durable touchscreen device that can withstand this use. 

Cracked Screens Continue to Function

Small cracks do not interfere with the function of a capacitive touchscreen device. It will continue to measure the electrical charge produced by the operator, using this information to determine where precisely the touch occurred.

Improved Picture

 Capacitive touchscreen devices have an exceptional quality picture. You’ll want to choose a capacitive model for this reason if you are planning to use the touchscreen device to watch movies, TV shows, and videos.


5. Benefits of Capacitive Touch Monitor

There are different advantages of using Capacitive touch screens compared to other technologies. Some of the benefits are listed below.


The pressure applied to register a touch is irrelevant because this technology relies on capacitance. And hence it is easier to use and lighter to operate.

Responsiveness is enhanced 

There is a chance of fewer accidental interactions because the objects with which a “touch” is registered are limited.


Capacitive touch screens are more durable and used in relatively harsh environments than other technologies.

Improved image quality 

Since the display screens have glass top layers instead of plastic layers, the image quality in these touch screens is much better.


The most significant benefit of this technology is that it will continue to function even with minor cracks on the screen; the capacitance will still be measured, thus ensuring the smooth functioning of your device.


6. Disadvantages of Capacitive Touch Screens Technology

It has a few disadvantages. Some of which are as follows

  • A capacitive touch monitor based on conductivity. It requires a special stylus that is conductors of electricity
  •  a capacitive touch screen tends to be costly
  • It is prone to breaking or cracking and requires a protective guard to protect the display screen.

7. Uses Of Capacitive Touch Screen 

Today, capacitive touch screens are used in almost every smartphone due to their efficiency and other advantages. The reason is that a capacitive touch screen gives a clearer picture than a resistive one. 

It is used in:

  • displaying computers, 
  • mobiles, 
  • Microsoft Surface laptops, 
  • Apple iPods, iPhones, and Ipods
  • other electronic devices. 


8. The Capacitive Touch Screen Benefit

Smartphones and other electrical appliances that employ touch screen technology are now essential in our lives.

Listed are some benefits that will bring to your organization are as follows

  • Capacitive touch screens are susceptible and maximize accuracy with potent sensors that more accurately detect your touch make your work efficient and save your time.
  • It requires less pressure to use and provides a longer shelf-life for your device.
  • It gives a better display and higher resolution, ensuring a better consumer experience.
  • Capacitive touch screen technology used for Multi-touch touch screens will help you perform various complex functions on your device
  • Capacitive touch screens with their dynamic functions have shown in a new area for touch screen technology. 

9. Choose Which Screen Is Better for Our Business

The type of touch screen you need is highly subjective to your business’s requirements that also depend on how much money you’re willing. And also able to spend on these devices.

The capacitive touchscreens tend to be a little more expensive because they are newer technological developments. They are worth investment for office-based businesses. 

10. Contact Points Of A Capacitive Touch Screen

When you want to use a screen with the ability to detect multiple points of contact, for example, when zooming with two fingers, in addition to the screen itself, you will need special software. This software must be adequate and powerful enough to understand what is happening on the screen regarding the electric field to avoid confusing the points that are being pressed.
