A resistive touch screen is made of a glass substrate as the bottom layer and a film substrate as the top layer, both coated with a transparent conductive layer (ITO: Indium Tin Oxide), separated by spacer dots to create a small air gap. The film substrate is typically clear polycarbonate or PET. ITO is made up of two conducting layers that are facing one another. The conductive ITO thin layers come into contact with a user's fingertip or stylus when they touch a specific area of the screen. Resistance is altered by it. The touch position is computed by the RTP controller after it notices the change. This voltage shift identifies the point of contact.
The ease of manufacture and low cost of production of resistive touch panels is one of the main reasons they are still in use. Low MOQ and NRE (Non-Recurring Expense) requirements apply. Driving is easy and inexpensive. The power usage is also minimal. Additionally, the resistive touch panel has good EMI resistance. It can use the overlay to make it flexible for designs even though it can't use the cover lens at the surface.
Touchscreens with resistive technology provide an unmatched level of durability. For precisely this reason, manufacturing businesses, eateries, and retailers frequently favor them over other kinds of touchscreens. Resistive touchscreens have a robust design that allows them to withstand moisture and stress without breaking down.
You can control a resistive touchscreen using a stylus or while wearing gloves. Most capacitive touchscreens only register commands performed with a bare finger (or a special capacitive stylus). If you use a stylus or a gloved finger to tap the interface, the capacitive touchscreen won’t respond to your command. Resistive touchscreens register and respond to all forms of input, though. You can control them with a bare finger, a gloved finger, a stylus, or pretty much any other object.
The biggest advantages of a resistive touch panel are its touch experience and clarity. It can only be used for single touch, no gestures or multi-touch. False touches can be generated if using two or more fingers to touch it.
The resistive touch panel’s transparency is relatively low. To prevent Newton rings or fingerprint marks, sometimes AG(anti-glare) film has to be used to make it look smoky. Optical bonding can’t be used for RTP. The surface of the resistive touch panel is soft and easily gets scratched.
Resistive touchscreens still have a couple of potential drawbacks. Resistive touchscreens are less sensitive than capacitive touchscreens. Although still responsive, a resistive touchscreen requires more force to recognize your input than a capacitive one.
Compared to capacitive touchscreens, resistive touchscreens typically have lower display resolutions. Of course, not every application needs a display with a high resolution. Resolution shouldn't be an issue if a touchscreen is used as a point-of-sale (POS) system in a retail setting, for instance.
