There is a difference in skills
The use of capacitive screen skills is later than that of resistive screens, and the skills are more advanced than resistive screens, and the price is naturally more expensive. This is what we often see, the same equipment of industrial tablet PCs, in terms of price, but there is a big difference, part of which is because of the difference in screens.
There is a difference in operation
The resistive screen adopts the form of pressure-sensitive operation, which can be operated by fingers, nails, stylus, etc.; The capacitive screen is positioned by using the current generated when the screen is in contact with the screen, and can only be operated with fingers, and cannot be operated by non-living organisms, such as nails and pens.
The hardness of the surface of the screen is different
The appearance of the resistive screen needs to be curved and the screen hardness is relatively low, and it is easy to apply the scratch process during application. As a result, resistive screen tablets often need to be protected by movies. The outermost layer of the capacitive screen is a glass lining, which is lubricated and strong and not easy to scratch. It can be used without shooting, and the effect is not affected by the glare.
Responsiveness
The response speed of an industrial tablet with a resistive screen is much slower than that of a capacitive screen. Users who have played the game have a deep feeling. In the process of swiping the screen quickly, invalid actions often occur. This type of industrial panel PC typically uses a resistive screen.
