touch screen display 42

touch screen display 42.The working principle is mainly as follows: if two adjacent rows / columns are energized, there is a fixed capacitance value C p as shown in FIG. 3 . If a human finger touches the surface of the touch screen, a capacitance is generated as shown in FIG. 4 . By row / column scanning , if the capacitance changes significantly, it is considered as a valid touch, and the controller can calculate the center position of the finger based on the new parasitic capacitance to calculate the X (Y) coordinate of the point on the screen By combining the upper and lower positions, a complete coordinate can be obtained. Because the upper and lower electrode surfaces are composed of multiple transparent electrodes that are not connected to each other, touching one point does not affect other parts, so multiple touch points can be identified at the same time.
