Capacitive touch screen technology uses the human body's current induction to work.

（SAW）Surface acoustic waves are mechanical waves that propagate along the surface of a medium. The corners of the touch screen are equipped with ultrasonic transducers.

Shenzhen GreenTouch Technology Co., Ltd has been in touch filed for 13 years, we have our own brand “GreenTouch”

Among the mainstream conference tablets in the smart office field, there are touch technologies such as infrared touch technology and capacitive touch technology. So, what are the principles of these different touch technologies? What are the differences?

When a single TP is used for testing. Please put an insulating material (such as foam, etc.) under the TP before testing, and you need to re-plug the USB cable after moving the TP or unplugging the FPC during the test to ensure normal touch.

The working principle,including 4 wire resistive touch screen and 5 wire resistive touch screen is mainly to realize the operation and control of the screen content through the principle of pressure sensing.
