## Capacitive Touchscreens vs. Resistive Touchscreens.
1. The main difference between capacitive and resistive touchscreens lies in how they detect touch input. Capacitive touchscreens use the electrical charge of the human body to detect touch, while resistive touchscreens rely on pressure applied to the screen to register input.
2. Capacitive touchscreens work by sensing changes in electrical charge when a conductive object, such as a finger, comes into contact with the screen. The screen is coated with a transparent conductive material, such as indium tin oxide (ITO), which forms an electrostatic field. When a conductive object touches the screen, it disrupts the electrostatic field, allowing the touchscreen controller to determine the position of the touch.
3. On the other hand, resistive touchscreens are made up of multiple layers, typically two flexible layers with a small gap between them. When pressure is applied to the top layer, it comes into contact with the bottom layer, creating an electrical connection at the point of touch. The touchscreen controller then determines the touch location based on the changes in electrical current flowing through the layers.
In summary, capacitive touchscreens detect touch input based on changes in electrical charge, while resistive touchscreens register input through pressure-sensitive layers coming into contact. Capacitive touchscreens are known for their responsiveness and multitouch capabilities, while resistive touchscreens are more durable and can be operated with gloves or a stylus.
