touch screen lcd

touch screen lcd.Capacitive touch screens are plated 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.
