The 5 Types Of Capacitive Touch Screen Monitor Technology

Touch screens are everywhere. You interact with a touch screen monitor constantly throughout your daily life. They can be found at the airport where you check into your flight, at automatic ticket vending machines on the train platform and even in some cash registers. Touch screens provide an efficient and intuitive option for interacting with digital devices on a large scale. While they make our lives easier, touch screens can be complex devices. So what are the different types of capacitive touch screen monitors?

The first 10.1 inch touch screen monitor was based on mutual capacitance technology. It had conductive leads at the bottom of the screen, which picked up changes in capacitance caused by objects nearing or touching the screen. This meant that you could not put anything over this type of capacitive touch screen monitor without disrupting its ability to sense input.

The capacitive touch screen monitors we see today are based on one of four technologies mutual capacitance, self-capacitance, projected capacitance or surface acoustic wave. Each type has its own advantages and disadvantages, which is why touch screens are found in such a wide variety of applications.

Resistive Touch Screen

This capacitive touch screen monitor type is the oldest and most commonly used. It relies on pressure from your finger to create a connection between two metal electrodes at the point of contact. A resistive touch screen monitor is “two-dimensional” because it can only detect input from one plane. This makes it less accurate than other types of capacitive touch screen monitors and susceptible to scratches and smudges.

Surface Acoustic Wave

A surface acoustic wave capacitive touch screen monitor uses high-frequency sound waves to detect input. When your finger contacts the screen, it disrupts the waves and causes a change in capacitance that is registered by the device. This type of capacitive touch screen monitor is very accurate and can be used in applications where water or wind may be present.

This capacitive touch screen monitor is often found on smartphones and tablet computers because of its light weight, high resolution and clear image quality. It scans your finger instead of detecting capacitance at a single point like the resistive touch screen monitor does. This capacitive touch screen monitor can determine not only the location of your touch but also its motion and size of the object touching the screen. This capacitive touch screen monitor is very durable, even when used with water or other liquids, because it uses sound waves to detect input rather than electrodes.

Projected Capacitive Touch Screen

This capacitive touch screen monitor is similar to the self capacitance type, but it uses a projector to create an image of your finger on the screen. This capacitive touch screen monitor has the advantage of being able to detect input from any direction, making it very accurate. It also has high resolution and can be used in direct sunlight because of its ability to adjust to changing light.

10.1 Inch Capacitive touch screen monitor are constantly evolving and improving. It is interesting to note that capacitive touch technology itself was developed by the gaming industry. A capacitance-based joystick controller was patented in 1977, but it wasn’t until 1981 that capacitive touch appeared commercially in devices like video game consoles.

If you are designing capacitive touch screen monitors or capacitive touch screens, capacitive touch technology is constantly improving and expanding to meet the needs of users. It is important to keep up with current capacitive touch technologies so your capacitive touch screen is always up-to-date and functional for your needs.

SAW (Surface Acoustic Wave) Touchscreen

A surface acoustic wave touchscreen (SAW touchscreen) is a type of capacitive touchscreen that uses high-frequency sound waves to detect input. When your finger contacts the screen, it disrupts the waves. And causes a change in capacitance that is registered by the device.

SAW touchscreens are very accurate and can be used in applications. Where water or wind may be present, i.e., outside of a building or vehicle.

SAW touchscreens can determine not only the location of your touch. But also its motion and size of the object touching the screen. This capacitive touch screen monitor is very durable because it uses sound waves to detect input rather than electrodes.

SAW touchscreens are typically found in smartphones and tablet computers. Because of their light weight, high resolution, and clear image quality. They also work well in direct sunlight because they can adjust to changing light levels.

IR (Infrared) Touch Screen

An infrared capacitive touch screen monitor works much like a SAW capacitive touchscreen. Except it uses light to detect input rather than sound waves. When your finger contacts the surface of the capacitive touch screen monitor. A beam of light is interrupted and a change in capacitance is detected.

IR capacitive touch screen monitors have many applications because they are unaffected by water or other liquids. They are often used in outdoor environments, such as manufacturing plants and airports, because they are very durable.

IR touch screen monitor can determine not only the location of your touch. But also its motion and size of the object touching the screen.

Advantage

  • Aesthetic appeal (no markings on screen)
  • unable to work in total darkness, but can measure ambient light and adjust accordingly.
  • OTF (Outgoing Transmitted Frequency) touch screen monitor

An OTF touch screen monitor is a capacitive touch screen monitor. That sends out a signal and detects any changes in capacitance. OTF capacitive touch screens are the most accurate type of capacitive touch screen monitors and can be used in all environments, including those with high levels of electro-magnetic interference (EMI).

Disadvantages

  • Cannot work in direct sunlight
  • Not as accurate as OTF capacitive touch screen monitor
  • More expensive than other types of capacitive touch screen monitors
  • Susceptible to electrostatic discharge (ESD)
  • Glass surface may be damaged by sharp objects

Conclusion

capacitive touch screen monitors come in a variety of types, each with its own advantages and disadvantages. It is important to select the touch screen monitor that is best suited for your needs. Capacitive touch screen monitors are constantly evolving. So it is important to stay up-to-date on the latest technologies.

Touch screen monitors have many practical applications. Because capacitive touch technology is so simple yet so accurate. Touch screen monitors can be found in smartphones, tablets, kiosks, ATMs, ticket vending machines and more!
