As we all know, there are mainly capacitive, resistive, infrared touch and surface acoustic wave screens on the market. Among these methods, capacitive screens and resistive screens are more popular among users of touch display devices. The significant difference between the two is that the capacitive screen can achieve multi-touch, while the resistive screen can achieve one-touch.
1.Technical principles
The industrial screen reacts with current and generates signals without pressure. To put it simply, the screen is divided into blocks, and a set of mutual capacitance modules are set up in each area to work independently, so that the touch situation in each area can be independently detected, and after processing, multi-touch can be achieved. For the demand for industrial screens, most users prefer capacitive touch screens. Capacitive touch screens not only support ten-point touch, but also have outstanding electrostatic anti-interference performance, which is more advantageous in scenarios such as power cabinets.
2. Simple correction
They can be installed and used once or produced without any calibration, whereas resistive technology requires routine calibration. After installing a capacitive touch screen on an industrial screen, the touch display manufacturer will simply touch it to check whether the screen is well connected with the machine's internal components.
3.Longer service life
Industrial screen capacitive touch screens have a longer service life because the components do not require any movement. The upper ITO film needs to be thin enough to be elastic so that it can bend downward to contact the lower ITO film.
4. Lower power consumption
From the perspective of touch technology, capacitive technology is superior to resistive technology in terms of optical loss and system power consumption, so this is also reflected in the advantages of industrial capacitive touch screens.
5. Routine operations are more convenient
For the choice of industrial screen touch mode, users need to consider the application scenario of the device. Choosing capacitive screen or resistive screen mainly depends on the objects on the touch screen. If it's finger touch, capacitive touch screens are a better choice. If you need a stylus, whether it's plastic or metal, a resistive touch screen will do the trick, or you can use a stylus, but you'll need a specialized stylus.
6. Small and medium-sized equipment is more suitable
For capacitive touch screens, large screens can implement capacitive touch on the surface, but they currently cannot support gesture recognition. Therefore, it is now mainly used for small and medium-sized touch display devices ranging from 7 to 21.5 inches, such as industrial screens, all-in-one computers, etc., and can support gesture recognition.
7. Low maintenance cost
Industrial screen touch screen, multi-finger touch will cause little damage to the screen, and the capacitive technology itself has the characteristics of wear resistance and long life, so the user's maintenance cost is also low, which can be said to help users save a lot of operating expenses.
