Why is the touch screen of car navigation not as good as the mobile phone?
Your question should be thought from two directions. First, the touch screen of car navigation is like the touch screen of a mobile phone, which is used by many original car GPS. Basically, capacitive touch screens are used, which is similar to the feeling of using a mobile phone, and is different from the resistive touch screens used by some commercial navigators. Second, using a capacitive touch screen does not mean that you don't press B if you want to press A, but it is affected by driving environment, strong outdoor light, high temperature and other factors.

Under normal circumstances, the resistance screen sometimes needs to be pressed hard to respond, while the capacitive screen is only needed in the case of long duration and complicated operation. For a car, the screen operation is not too complicated, just one button. It's not a mobile phone. You don't need multi-touch to play games on it.

In addition, capacitive screens are hard screens, and glass is easy to stab people after an accident, but resistive soft screens are safer. Moreover, the hard screen with glass and the strong shaking of the car are also easy to damage the tempered glass capacitive screen, so it will be banned in some automobile production standards. Of course, the cost of resistance screen is basically lower than that of capacitive screen, which is also a big factor.

The touch sensitivity of the touch screen of resistive or capacitive car navigator is often disturbed. The resistance screen will drift when used for a long time, and it is also very laborious to correct it; And when there is no static electricity in your hand, the capacitive screen can't be controlled. So there is another infrared touch screen system. This is a system that locates by photoelectric detection. It locates two-dimensional space by using the characteristics of good directivity and accurate positioning of infrared rays, and eliminates the interference caused by ambient light and internal switches of the system by using small signal amplification circuit and square wave shaping circuit. But at present, capacitive touch screen has not been popularized, and infrared touch screen has to wait for popularization.

Car navigation generally uses resistance screens, and mobile phones generally use capacitive screens. Capacitive screen represents Apple series products, and has an extraordinary touch experience that other products can't surpass, which has made great contributions to the successful promotion of capacitive screen. For example, the smart car brain uses the Kangding chimpanzee three-generation screen. Apple products are the first generation, the screen does not reflect light, only absorbs light, and looks very comfortable.

? Advantages compared with resistance screen: Advantages: The screen cost and control system are relatively cheap, and the response sensitivity is also very good. Moreover, whether it is a four-wire, five-wire, seven-wire or eight-wire resistive touch screen, it is completely isolated from the outside world, not afraid of dust and water vapor, and can adapt to various harsh environments.

It can be touched by any object and has good stability. Capacitive screen: Advantages: high touch sensitivity, easy to realize multi-touch, better light transmittance and clarity than resistance screen, and high screen hardness. I feel that the price of resistance screen for car navigation is also a factor.
