What is a capacitive screen and a resistive screen

Capacitive screens and resistive screens are two types of touchscreen technologies used in electronic devices such as smartphones, tablets, and GPS navigation systems.

A capacitive screen uses an electrical charge to detect when a conductive object, such as a finger, comes into contact with the screen. This type of screen provides a more accurate and responsive touch experience, making it easier to perform actions such as pinch-to-zoom and swipe gestures. However, capacitive screens are less sensitive to non-conductive objects, such as gloves or styluses, and can be more expensive to manufacture.

On the other hand, a resistive screen uses two layers of conductive material that are separated by a small gap. When pressure is applied to the screen, the layers touch, and the location is detected. This type of screen is more affordable to manufacture and can be used with a stylus or even a gloved hand. However, resistive screens can be less accurate and less responsive than capacitive screens.

In summary, the main advantages and disadvantages of capacitive screens and resistive screens are:

Capacitive screens: 

Advantages: more accurate and responsive touch experience, better for multitouch gestures, can be used with a bare finger.

Disadvantages: less sensitive to non-conductive objects, more expensive to manufacture.

Resistive screens: 

Advantages: more affordable to manufacture, can be used with a stylus or gloved hand.

Disadvantages: less accurate and less responsive touch experience, not ideal for multitouch gestures.
