At present, the touch screens often sold on the market are capacitive touch screens and resistive touch screens. What's the difference between capacitive touchscreen and resistive touch screen?
1. The first difference between capacitive touchscreen and resistive touch screen: comparison of damage resistance.
The outermost layer of the capacitive screen has a glass protective layer, which may break under the action of external force. The outermost of the resistive screen is a thin film, which needs to be pressed to form a pressure sensor, and the resistive screen supports a stylus, so the screen is prone to scratches, needs to be protected by protective film, and needs to be calibrated frequently, which is not easy to break relative to the capacitive screen.
2. The second difference between capacitive touchscreen and resistive touch screen: comparison of touch sensitivity.
The capacitive screen works by using the current induction of the human body, so any non-conductive objects such as nails and gloves can not be recognized by capacitance sensors. The resistance screen works through a pressure sensor, can be touched by any object, and supports a stylus.
3. The third difference between capacitive touchscreen and resistive touch screen: the comparison of the feasibility of multi-touch.
The resistive screen does not support multi-touch, and sharp, insulated objects such as fingernails and stylus can be controlled; the capacitive screen relies on the capacitance formed by the human body and the electrode to achieve positioning. It must be touched by the skin or other objects that can conduct electricity. It is impossible to control the industrial tablet computer with fingernails, stylus and so on.
