In today’s world, touch screen technology has become an integral part of our daily lives. From smartphones to ATMs, we use touch screens almost everywhere. Resistive touch monitor are one of the most commonly used touch screens. In this blog post, we will discuss how resistive touch monitor work.
A resistive touch monitor comprises two transparent layers of conductive material, usually indium-tin oxide (ITO), separated by thin spacer dots. The bottom layer is attached to the display screen, while the top layer is attached to a flexible plastic film. When pressure is applied to the top layer, it touches the bottom layer, completing the circuit, and a voltage drop occurs.
When you touch a resistive touch monitor, the top layer makes contact with the bottom layer at that point, causing a change in voltage. The change in voltage is detected by the controller chip, which calculates the exact location of the touch. The controller chip then sends the information to the device’s processor, which translates it into a specific action.
One of the primary advantages of resistive touch monitor is that they are relatively inexpensive and easy to manufacture. They are also highly accurate and can detect touch from any object, including a stylus or gloved hand. However, they have some drawbacks, such as lower image clarity due to the two layers of material, less sensitivity, and lower durability than other touch technologies.
In conclusion, resistive touch monitor work by two layers of conductive material coming into contact, completing a circuit and sending a signal to the device’s processor. While they have some drawbacks, their low cost and accuracy make them a popular option for various devices, such as point-of-sale terminals, industrial controls, and medical equipment.
