For the touchscreen to work, it needs to get in contact with the human body, which stores an electrical charge. This layer also functions as coordinates. Ĭapacitive touchscreen displays are only composed of a single layer.
Resistive touchscreen displays are not capable of accommodating several fingers simultaneously since the software can only distinguish a single point of contact. The software acknowledges this change and starts to perform its task of either opening, closing or swiping an application. This point of contact leads to a change in electric current. Whenever you touch the screen, its resistive layer has a hard feel and gets in touch with the conductive layer. These layers both come with electric currents and are kept apart from each other one is resistive while the other is conductive. To work, it relies on pressure from the user’s touch. The resistive touchscreen is composed of two layers.
There are two common types of touchscreens used in laptops the resistive type and the capacitive type.
