1. Consider the Response Speed of Panel PC
Many friends know that capacitive screens are definitely stronger than resistive screens. Resistance screens need to be pressed and touched. Capacitance screens are like mobile phones that people keep their hands on all day long, and they respond when touched lightly.
2. Considering the Surface Hardness of Panel PC
Its hardness is low, that is, it has a soft feeling on the painting. Because the surface of resistance screen should be bent induction, and the outer layer of capacitance screen is usually glass lining, smooth and hard. This is a difference. Then there are scratches on the surface. It can also be used without film sticking. In fact, for high-quality capacitive screens, the film is only used to prevent fingerprints from being left on them. But the resistance screen should be protected by film, because the screen itself is fragile, and the protection without film is easy to break down and there will be too much scratch.
3. From the technical point of view of constituting panel pc, the technology of capacitive screen is relatively high-end.
The application of capacitive screen technology is later than that of resistive screen. In popular words, capacitive screens are more expensive than resistive screens. Many times, we see that there is little difference in the allocation of hundreds of yuan and thousands of yuan for many price tablets. Part of the problem is screen differences.
4. Compare the differences between the two in terms of the way panel pc is operated
Resistance screen is the operation mode of pressure induction. Any object can be sensed as long as it bends on the screen surface. The working principle of capacitive screen is different. When the user touches the capacitive screen, the electric field of the human body and the working surface of the finger 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 of the four corners of the screen separately, and theoretically flows through four electric currents. The current is proportional to the distance from the finger to the four corners. The position of the controller is obtained by precise calculation of the four current ratios. Therefore, the capacitive screen is a human touch operation, without pressing.
