Resistive Touch Screen Panel

Product Description

In order to measure a coordinate on specific direction of resistive touch screen, resistive touch screen panel needs to bias one resistive layer: one side is connected to VREF and the other side is grounded. At the same time, will not offset the layer connected to the high impedance input terminal of a ADC. When the pressure of the resistive touch screen panel is large enough, the contact between the two layers, the resistive surface is divided into two resistance. Their resistance and touch points to offset edge is proportional to the distance. The resistance between the touch point and the ground side of the equivalent of the resistor divider in the following. Therefore, the voltage measured on the offset layer is directly proportional to the distance between the touch point and the ground edge.            


Advantages and disadvantages of resistive touch screen 

The advantages of resistive touch screen panel is the screen and its control system are relatively cheap, sensitivity is also very good, but whether it is four or five wire resistive touch screen resistive touch screen, they are a completely isolated on the outside of the work environment, not afraid of dust and water vapor, can adapt to the harsh environment. It can be used to touch any object, good stability.

The disadvantage is the outer membrane of the resistive touch screen panel is easy to scratch the touch screen is not available, the multilayer structure will lead to great loss of light, for handheld devices usually need to increase the backlight to compensate the light is not good, but it will also increase the consumption of battery.
