How to choose the touch mode of industrial tablet?
1、 Response speed:
As many friends know, capacitance screen is certainly stronger than resistance screen. The resistance screen needs to press the touch, and the capacitance screen is just like a mobile phone that people can't leave their hands all day long. A touch gives a reaction.
2、 Surface hardness:
The hardness is low, that is, there is a soft feeling on the painting. Because the surface of the resistance screen should be bent and induced, while the outer layer of the capacitance screen is usually glass lining, smooth and hard. It's a difference. Then there are scratches on the surface. Film can also be used without film. In fact, for the high-quality capacitor screen, the purpose of film pasting is to prevent fingerprints from being left on it, but the resistance screen generally needs to be protected by film pasting, because the screen itself is relatively fragile, and it is easy to break or scratch without film pasting protection.

3、 From a technical point of view, the capacitor screen technology is relatively high-end.
The application time of capacitor screen technology is later than that of resistance screen. In common parlance, capacitance screen is more expensive than resistance screen. So that's a difference. A lot of times we see that the configuration difference of a few hundred and a few thousand tablets with many prices is not big. Part of the situation is caused by the screen difference.
4、 There are differences between them in operation mode:
Resistance screen is the operation mode of pressure sensing. Any object can be sensed as long as it causes bending on the screen surface. The working principle of the capacitive screen is different. When the user touches the capacitive screen, the human electric field of the finger and the working surface form a coupling capacitance. Because there is a high frequency signal on the working surface, the finger absorbs a very small current, and the current flows out from the electricity on the four corners of the screen respectively. In theory, the current flowing through the four electricity is proportional to the distance from the finger to the four corners, controlling The position of the brake is obtained by precise calculation of four current ratios. Therefore, the capacitive screen is operated by human touch without pressing.
