 Touchscreen devices are common these days and cover a majority of technological gadgets.  Most of these devices use either resistive or capacitive types of touchscreens. The general difference is that resistive touchscreens identify the origin of a touch when two layers are pressed together, similarly to the keypad on a microwave oven. This type of touch screen is known as a membrane switch. Capacitive devices function by identifying the electrical coupling produced by the operator’s touch.  To make it more clear, we have five simple points to understand the differences between the two types of touchscreens - resistive and capacitive.  Different Method of Input The two types of touchscreens use a different method of input and mark a notable difference between these.  Devices with capacitive touchscreens offer a single method of input i.e. direct finger or special stylus touch only. Whereas devices with resistive touchscreens offer multiple input methods like direct bare finger touch,

 The existence of touch screen monitors has been around almost as long as computers themselves. But the added features made it more capable and efficient for use in different industries and for various purposes. The main gain of a touch screen is its versatility as an input device. A touch screen can replace the need for a keyboard and mouse. Resistive touch screens work utilizing a flexible transparent conductive membrane fixed to a similarly conductive coated glass substrate both separated by tiny spacer dots. An electrical current is applied to one of the the two layers and when an operator touches the screen, the membrane layer contacts the substrate glass and a voltage is read by the opposite layer. The touch screen controller then computes the touch coordinates by way of an analogue to digital circuit. This process is done for both the X and Y planes at high speed.  4-Wire Resistive Touch Screens are very efficiency and draw a very low amount of power. It has a range of features
