13 inch touch screen laptop.In addition, narrow electrodes are plated on all four sides of the additional touch screen to form a low-voltage AC electric field in the conductive body. When the user touches the screen, a coupling capacitance is formed between the human body's electric field, the finger and the conductor layer. The current from the four electrodes will flow to the contact, and its strength is proportional to the distance between the finger and 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.
