The Advantage And Disadvantage Of Capacitive Touch Screen Kit

With the development of science and technology, our lives are becoming more and more intelligent now. Now many smart terminals have use the capacitive touch screen. As a special display external device, capacitive touch screen kit is currently the simplest, convenient and natural way of human-computer interaction. It brings a lot of convenience to our lives. Today, let us discuss the advantages and disadvantages of the capacitive touch screen kit.

The Advantages of capacitive touch screen Kit

The capacitive touch screen kit is because the current of the human body and the conductive layer form a capacitive field, and the touch screen works. It is not like a resistive touch screen, which requires external pressure to generate a signal. So you only need to touch with your finger to click the content you want.

The capacitive touch screen is automatically calibrated, you only need to plug in the capacitive touchscreen, and it will automatically calibrate according to the content of your display. The resistive screen often needs software to assist in calibration.

The life of the capacitive touch panel will be longer, because the parts in the capacitive touch screen do not need any movement.

How to choose which touch screen technology? Mainly depends on what touches the screen. If you just use finger to touch, a capacitive touch screen is a better choice. If you need a stylus, whether it is plastic or metal, a resistive touch screen can do the job. The capacitive touch screen can also use a stylus, but it needs a special capacitive stylus to cooperate.

The Disadvantages of capacitive touch screen Kit

The light transmittance and clarity of the capacitive touch screen is better than that of the four-wire resistive touchscreen. But it can't be compared with surface acoustic wave touch screen and five-wire resistive touch screen. The capacitive touch screen has serious reflections, especially under strong light. It makes it difficult to see the contents of the display.

Moreover, the four-layer composite touch screen of capacitive technology has uneven light transmittance to light of various wavelengths. What’s more , it has the problem of color distortion. The reflection of light between the layers also causes blurring of image characters.

Although the capacitance value is inversely proportional to the distance between the poles.It is directly proportional to the relative area and is also related to the insulation coefficient of the medium. There is another disadvantage that it does not respond to ordinary capacitive touch screens when they touch with gloved hands or non-conductive objects. This is because a more insulating medium is added.
