In electrical engineering, resistive touch screen is coated with a resistive touch materials and two elastic plates separated by an air gap or microdots composed of computer monitors. There are two different types of metal layers. The first type is known as a matrix, in which the substrate, such as glass or plastic strip electrodes facing each other. The second type is called simulation which consists of a transparent electrode pattern does not face any other. When the contact on the touch screen to the surface of the two pieces are pressed together. These two sheets at a horizontal and vertical lines, when pushed together, the precise location of the touch register. Since the contact sensing inputs touchscreen almost any object (finger, stylus / pen, palm) resistive touch screen is a "passive" technology.

For example, during operation of a four-wire touchscreen, a uniform, unidirectional voltage gradient is applied to the first sheet. When the two sheets are pressed together, the second sheet measures the voltage as distance along the first sheet, providing the X coordinate. When this contact coordinate has been acquired, the voltage gradient is applied to the second sheet to ascertain the Y coordinate. These operations occur within a few milliseconds, registering the exact touch location as contact is made, provided the screen has been properly calibrated for variations in resistivity.

Resistive touchscreens typically have high resolution (4096 x 4096 DPI or higher), providing accurate touch control. Because the touchscreen responds to pressure on its surface, contact can be made with a finger or any other pointing device.

Resistive touchscreen technology works well with almost any stylus-like object, and can also be operated with gloved fingers and bare fingers alike. In some circumstances, this is more desirable than a capacitive touchscreen, which needs a capacitive pointer, such as a bare finger (though some capacitive sensors can detect gloves and some gloves can work with all capacitive screens); resistive touchscreens, due to requiring harder pressure, are also more accurate than capacitive touchscreens. Costs are relatively low when compared with active touchscreen technologies, but are also more prone to damage.Resistive touchscreen technology can be made to support multi-touch input.

For people who must grip the active portion of the screen or must set their entire hand down on the screen, alternative touchscreen technologies are available, such as active touchscreen in which only the stylus creates input and skin touches are rejected. However, newer touchscreen technologies allow the use of multi-touch without the aforementioned vectoring issues.

Where conditions allow bare finger operation, the resistive screen's poorer responsiveness to light touches has caused it to lose market share to capacitive screens in the 21st century.
