Why Does The Usb Capacitive Touch Panel Sometimes Fail To Respond When Wearing Gloves In Winter?

With the rapid development of technology, more and more Usb Capacitive Touch Panel are now applied to various products. Because of the arrival of capacitive touch screens, it has brought great benefits to our lives. So everyone likes to use capacitive touch panel. Recently, a customer asked why the touch screen does not respond when wearing gloves in winter? So let's talk about this issue today.

The Reason Why The Usb Capacitive Touch Panel Sometimes Does Not Respond When Wearing Gloves In Winter:


1) The Working Principle Of Usb Capacitive Touch Panel

Sometimes there is no response when operating the touch screen with gloves in winter, and the problem is not with the gloves. But because many products are now capacitive touch screens. The principle is when the finger touches the capacitive screen. Due to the electric field of the human body, the finger and the working surface form a coupling capacitor. Because there are high-frequency signals connected to the working surface. So the finger absorbs a very small current. This current flows from the electrodes on the four corners of the screen. And theoretically, the current flowing through the four electrodes is proportional to the distance from the finger to the four corners. The controller obtains the position through precise calculation of the ratio of the four currents.

2) Low Dielectric Constant Of Gloves

However, gloves made of knitted, woven materials or wool-like materials have many large holes. Therefore, the dielectric constant is very low, which insulates the finger from the sensor electrode. Therefore, the response of the touch screen will be affected and become insensitive. In addition, whether the gloves are very wet, whether they contain detergent plasma compounds, etc., will also have a great impact on the capacitive touch sensor.

Touch Screen Solution With Gloves:

When capacitive touch screens first became popular, it is true if you are wearing gloves. The capacitive touch screen is really difficult to react when touched. But with the continuous update and iteration of the chip. The solution for touching with gloves is now very mature. Because in general industrial and medical applications, many need to wear gloves to operate the touch screen. So if you have a touch screen solution that requires gloves, please feel free to contact us.
