Types of Electromagnetic Touch Screen

The electromagnetic touch screens produced by our company mainly include the following types:

10.9 Inch Electromagnetic Touch Screen

One of the advantages of electromagnetic induction touch screens is its high precision and sensitivity. They are capable of detecting subtle changes in the electromagnetic field, enabling extremely accurate touch positioning.

15.6 Inch Electromagnetic Touch Screen Panel

The fundamental operating principle of electromagnetic induction touch screens relies on the varying magnetic fields generated by the electromagnetic pen and the underlying sensor.

17 Inch Electromagnetic Touch Screen

This technology is widely used in various applications, including tablet computers, drawing tablets, and digital signature devices. It offers users a natural and intuitive input method and is particularly useful in scenarios that require high precision and fine control, such as drawing, handwriting, and design.

Advantages of Electromagnetic Touch Screen

Precise Positioning
High accuracy across all parts of the active area. Since the high-frequency electromagnetic signals emitted by the pen are less susceptible to external interference, the algorithm can accurately locate the pen tip.

Long Lifespan and Low Replacement Cost
The positioning antenna board is located beneath the touch surface, meaning it doesn’t directly interact with the positioning equipment. Unlike resistive or capacitive screens, where touch operations are performed directly on the surface, leading to potential scratches or wear over time, electromagnetic screens are more durable.

Excellent Light Transmission
Since the touch layer is not installed on top of the LCD screen, it allows for better light transmission.

Strong Anti-Interference
It is resistant to interference from light, temperature, humidity, and noise, making it suitable for various environments, both indoors and outdoors.

Pressure Sensitivity Support
It can accurately reflect the user’s writing pressure, perfectly reproducing the authentic handwriting based on the force applied.

Precautions for Using Electromagnetic Touch Screen

If you change the display resolution or display mode of the touch screen when operating the electromagnetic touch screen, or adjust the refresh frequency of the touch screen controller by yourself, and feel that the cursor and the touchpoint cannot correspond, you must calibrate the touch screen system again.

In order to ensure the normal operation of the touch screen system, in addition to ensuring the correct installation of the system software, it is also necessary to remember not to install two or more touch screen drivers on one host, which will easily cause conflicts occurring when system running and prevents the touchscreen system from functioning properly.

When using the electromagnetic touch screen, if the cursor does not move or can only move in a local area, the user can check whether the touch area of the touch screen is always pressed by other touch objects.

When there are inaccurate clicks or drift when the system changes the display, adjusts the screen size, or the first installation of the system, you need to start the positioning program that comes with the application to reposition, but it is best to use a relatively thin pen or fingertip for positioning when positioning, which is more accurate.

The working environment of the surface acoustic wave touch screen has high requirements. It must work in a clean and dust-free environment, and the dust on the surface of the touch screen should be cleaned regularly.

Do not let water droplets or other soft things stick to the surface of the touch screen, otherwise, the electromagnetic touch screen is easy to mistakenly think that the surface acoustic wave screen is touched by hand, which could cause inaccuracy of the surface acoustic wave touch screen.

Packaging and Shipping

Packaging

1. Honeycomb cartons are used outside, and pearl cotton is used inside the honeycomb cartons.

2. The goods exported to foreign countries will be packed in additional wooden boxes outside the honeycomb carton due to the impact of the humid environment of sea transportation or the impact of air transportation.

3. The packaging method can be customized according to customer requirements.

Shipping

We will help you to choose the best shipping way according to your detail requirements. By sea, by air, or by express, etc.

FAQ

Q: What is an electromagnetic touch screen?

A: An electromagnetic touch screen utilizes electromagnetic technology to detect and respond to touch input. It typically involves a grid of wires embedded in the screen that interacts with a stylus or pen emitting an electromagnetic signal.

Q: How does an electromagnetic touch screen work?

A: Electromagnetic touch screens work by detecting changes in the electromagnetic field caused by the stylus or pen when it comes into contact with the screen. This allows for precise positioning and pressure sensitivity, making it suitable for tasks that require accuracy and detail.

Q: Are electromagnetic touch screens compatible with fingers?

A: Electromagnetic touch screens are primarily designed for use with a stylus or pen that emits an electromagnetic signal. While they may not be optimized for finger touch input, some models may support limited finger touch functionality.

Q: Can electromagnetic touch screens work with gloves?

A: Since electromagnetic touch screens rely on the interaction between the stylus/pen and the screen, they may not be compatible with gloves unless the gloves are specifically designed to work with such screens or have conductive material on the fingertips.

Q: How do you clean an electromagnetic touch screen?

A: Use a soft, dry cloth to gently wipe the screen. If there are stubborn stains, a small amount of mild cleaning solution can be used, but make sure to avoid getting the solution into the edges or openings of the device. Do not use abrasive cleaners or rough cloths that could scratch the screen.

Q: How often should the electromagnetic touch screen be calibrated?

A: The frequency of calibration depends on the usage and the device. Generally, if you notice a decrease in the accuracy of the touch screen, it may be time to calibrate it. Some devices may require calibration every few months, while others may need it more frequently, especially if they are used heavily or in harsh environments.
