The advantages of capacitive touch-screen



Capacitive touch screens require only touch, without the need for pressure to generate signals.

Capacitive touch screens require only one or no correction at all after production, and resistance technology requires regular calibration. The capacitance scheme has a longer lifespan because the components in the capacitive touch screen do not need any movement.

In resistive touchscreen, the ITO film on the upper layer needs to be thin enough to be flexible so that it bends downward to contact the Ito film below.

Capacitance technology outperforms resistive technology in light loss and system power dissipation. The choice of capacitive or resistive technology depends primarily on the object that touches the screen. Capacitive touch screen is a good choice if you touch the finger. If you need a stylus, whether it is plastic or metal, the resistive touch screen can do the job.

The capacitive touch screen can also use a stylus, but requires a specially crafted stylus to fit.

Surface capacitance can be used for large-size touch screens, and this is also low, but the current cannot support gesture recognition: inductive capacitance is mainly used for small and medium-sized touch screen, and can support gesture recognition.

Capacitive technology is wear-resistant, long life, low maintenance costs for users, so the overall operating costs of the manufacturer can be further reduced. Capacitive touchscreen is the ability to support multi-touch technology, and is not as slow as the resistive touch screen and not easy to wear.
