What is the technical principle of touch screen

The touch screen senses the touch of our fingers because when the fingers touch a specific position on the screen, it is equivalent to sending an accurate electronic signal to the screen. There are many types of touch screen, which can be roughly divided into resistive touch screen and capacitive touch screen. At present, the […]

Knowledge analysis of resistive touch screen and capacitive touch screen

At present, there are several types of touch screen, they are: resistance type (double layer), surface capacitance type and induction capacitance type, surface acoustic wave type, infrared type, bending wave type, active digital converter type and optical imaging type. They can be divided into two categories, one needs ITO, such as the first three touch […]
