Top 10 Advantages and Disadvantages of Capacitive Touchscreen


When you use touch phones and POS devices, have you ever wondered why you could control them by touch? Yes, capacitive touch screen technology can achieve these functions. Now let's read the following article to learn about capacitive touch screen technology.


Do you want to know what the capacitive touch screen means?

A capacitive touch panel is a control display that uses the conductive touch of a human finger or a specialized device for input.
Capacitive touchscreen devices are typically handheld and connect to networks or computers via an architecture that supports various components, including satellite navigation devices, personal digital assistants and mobile phones.
A capacitive touchscreen glass is activated by human touch, which serves as an electrical conductor used to stimulate the electrostatic field of the touch screen. However, special gloves that produce static electricity or specialized stylus pens may be used.

How Capacitive Touch Panels Work?

Capacitive sensors are used to detect the position of the touch. Capacitive touch screens are designed to sense the human touch.
In capacitive touchscreen display, glass panel of a particular device is covered with a capacitive layer with a static charge when we touch a finger on the screen some of the charge shifts from the device to the finger.
This decreased charge is noticed by the system. The system processed the information to the program which tells the exact location of a touch

View the video explanation of the capacitive touch panels:


Capacitive touch screen panel glass types are as follows:

  • Projected Capacitive Touch (PCT): Uses etched conductive layers with electrode grid patterns. It has robust architecture and is commonly used in point-of-sale transactions.
  • PCT Mutual Capacitance: A capacitor is at each grid intersection via applied voltage. It facilitates multitouch.
  • PCT Self Capacitance: Columns and rows operate individually via current meters. It has stronger signal than PCT mutual capacitance and functions optimally with one finger.
  • Surface Capacitive touchscreen: Coated on one side with small voltage conductive layers. It has limited resolution and is often used in kiosks.

The Capacitive Touchscreens Kit Uses:

  • • Tablets
  • • Smartphones
  • • Android phones
  • • Microsoft Surface
  • • Advertising device
  • • Subway ticketing equipment
  • • Bank automatic withdrawal device
  • • Apple’s iPhone, iPad and iPod Touch
  • • So etc

Top 10 Advantages of Capacitive Touch Screens

Easy to learn and use

It turns out that the touch screen is very intuitive to use. This is why using a capacitive touch screen in an application helps eliminate errors.
Choosing the right button or menu item on the screen has never been easier. You just need to point it out. The on-screen buttons can be as big as necessary. Make sure that all users have a clear view of the button and know where to touch to select a feature or feature. capacitive touchscreen stylus requires little coordination by the user. The final benefit of the touch screen is to help users protect system content from unauthorized access. Always ensure that the right users can interact with the right content and information.

Incredible durability

Of course, the main advantages of capacitive touch screen technology are its strength and durability. Touch screen devices have seen many uses over the years, especially in commercial applications.
When your application or the environment of the application can be described as harsh a capacitive touch screen is the way to go. Capacitive touch screens are typically more robust than resistive touch screens.
They can better withstand demanding use in difficult environments. When the touch solution is frequently used resistive touch screens tend to show some wear. MMake them not respond in the heavy use area. Capacitive touch panel does not have this problem.

Easy to Clean

The tft lcd capacitive touch screens have a durable glass top layer. So, a Capacitive Touch Screen is not affected by dirt, rain, grease or dust.
Capacitive Touch screens are very well adapted for public use and applications that require heavy usage.

The most reliable in touch screen

Cracked touch screen glass continue to function. TFT capacitive touchscreen are more likely to continue to work when damaged. Cracked screens are among the most common type of damage sustained by touchscreen devices.
We almost hope that the HMI Operator Panel continue to work as usual, even when the screen is broken, shattered or pierced,
But the resistive touch screen will almost always stop working if any part of the screen is broken.
Anyway, minor cracks should not interfere with the function of the capacitive touch panel device. It will continue to measure the charge generated by the operator controller and use this information to determine the exact location where the touch occurred.

Support personalized customization

One of the biggest benefits of capacitive touch screens is the fact they are usually all-in-one solutions. The factory can customize different sizes of a capacitive touch screen according to customer needs.
Capacitive touch panel controller / touch monitors save space on desks as a mouse or keyboard is not needed. Integrating everything into the display helps save us valuable space. Integrating data entry with the display saves space in the final device

Sharper images with better contrast

The big difference between resistive and capacitive touch screens is the top layer. Capacitive touch screen devices have extraordinary picture quality thanks to their use of a glass layer.
Resistive touch screens have a flexible plastic layer. Glass is more clear than plastic, greatly improving the image quality of a capacitive touch screen compared to a resistive touch screen.
If you’re planning to use the touchscreen device to watch movies, TV shows or videos, you’ll probably want to choose a capacitive model for this reason.

More sensitive to light touch

Because capacitive touchscreens register touch via the human body’s electrical current, they require less operating pressure than resistive touch panel glass.
You can usually operate a capacitive touch screen simply by dragging your finger across the surface. This is in stark contrast to resistive touchscreens, which typically require a firm, medium-pressure press.

Provide multi-touch sensing

Projected capacitive touch screens are very similar to conventional capacitive touch screens. Projected capacitive touch screens make multi-touch possible, which is a big advantage for these types of touchscreen capacitive.
It allows gesture touches and functions such as pinch zoom. This is very beneficial for your application and allows you to do more as you want.

Efficient work and cost reduction

Use the touch screen interface to increase accuracy and reduce time spent on devices.
This will increase efficiency and ultimately reduce costs.
Users of touch screen devices can respond quickly without making errors. This will increase efficiency and ultimately reduce costs.

Better development prospect

One of the greatest benefits of touchscreens is the intuitive interaction between user and device. We uses a touchscreen interface in life that is usually capacitive,such as tablets, smartphones, Microsoft Surface, etc. Therefore manufacturers around the world are committing to touchscreen technology.
We believe capacitive touch screens will become the technology of choice for many different industries. This means advancements will most likely be designed to fit capacitive touch. They are making the technology future proof and compatible with developments.

Disadvantages of Capacitive Touch Screens

The glass is more susceptible to crack damage

The top glass layer makes the capacitive touch panel extremely durable and reliable. They are not susceptible to scratches and other damage as well as external influences.
But glass is easier to break than plastic and even though breakage doesn't affect the touch screens a lot. We can add a protective layer like thermally hardened glass in the future

Cannot be used with most gloves--Limited touch object

Where human touch makes work easy and quick on small and standard sized appliances there, it becomes problem on a wide screen or if it is placed at higher place.
Like it is not suitable for projectors because you cannot use hand everywhere and it becomes difficult to explain a higher point on the projector where your hand is not able to reach.
Here is another limited, the need for a conductive object eliminates many other touch objects, such as a gloved finger.
