21 inch touch screen

21 inch touch screen.Capacitive touch screens are coated with narrow electrodes on all sides of the touch screen to form a low-voltage AC electric field in the conductive body . When the screen is touched, due to the electric field of the human body, a coupling capacitance is formed between the finger and the conductor layer. The current from the four electrodes will flow to the contact, and the current strength is proportional to the distance from the finger to the electrode. Will calculate the proportion of current and strength to accurately calculate the position of the touch point. The double glass of the capacitive touch screen not only protects the conductors and sensors, but also effectively prevents external environmental factors from affecting the touch screen. Even if the screen is stained with dirt, dust or oil, the capacitive touch screen can still accurately calculate the touch position.
