What's the difference between a capacitor screen and a resistive screen
- May 10, 2018 -

The appearance of resistive screen in the year of domestic large-screen shanzhai machine red. It was the standard match of the shanzhai machine. With the advent of high-end capacitive screens such as apple's iphone, the resistive screen has lost its competitiveness and is slowly being cooled by people. The difference between a resistive screen and a capacitive screen is described below. And by the way, some knowledge about resistive screens and capacitive screens.

From a technical point of view, the application of capacitive screen technology is later than resistive screen. Capacitive screen technology is relatively high-end. In popular terms, a capacitive screen is more expensive than a resistive screen. So that's the first difference. A lot of times we see a lot of flat-rate flat-panel, a few hundred and a few thousand configurations that are not very different, and part of it is the screen difference.

There's a difference in the way we do things, and the common joke is that we buy an iphone and we get a stylus. The implication is that the stylus is a resistive screen. The resistive screen is a pressure-sensitive operation that can be induced by any object that bends on the surface of the screen. Working principle of the capacitive screen, on the other hand, when a user capacitive touch screen, the user the fingers of the human body and face to create a coupling capacitance, because the working plane to have a high frequency signal, so the fingers on a very small current, respectively from the screen and the current issue on the four corners of the electrode, and theoretically through the four electrode current is proportional to the distance with the finger to the four corners, the controller through the precise calculation of the four current ratio, it is concluded that location. So the capacitive screen is a human touch operation that doesn't need to be pressed.

Surface hardness. Because the surface of the resistive screen should be curved, the hardness is low, which is to have a soft feel. And the capacitive screen is usually the outermost layer of glass, smooth and hard. This is a difference.

And then there's the scratches on the surface. In fact, for the high quality capacitive screen, the film is only to prevent the fingerprints from being left on, and it can also be used without the film. However, the resistive screen is generally protected by the film, because the screen is fragile, and the protection of the film is easy to be broken and too much scratches.

Response speed. A friend who has used a shanzhai or resistive screen to cut fruit must know that the response is slow. High-end capacitive screens respond very quickly in just a few milliseconds.

Multipoint control, although not all capacitive screens are multipoint control. But there is a conclusion that not all single electronic controls are resistive screens, but the multipoint control is basically a capacitive screen. Multi-point control technology makes the operation of capacitive screen more convenient and more casual. That's one of the big advantages.

Finally, compare the universality of the application. Resistive screens used to be popular on shanzhai phones, and as the shanzhai disappeared, the resistive screens are now only available on low-end tablets. And the capacitive screen is divided into different grades, and it is used on the phone tablet of all grades. So now capacitive screens are more mainstream.
