Resistive or Capacitive Touch Screen

Resistive touch screens operate by sensing direct pressure applied by the user. It can be activated by pressing it not only with a finger but also with a stylus (unlike the competing capacitive technology).

A resistive touch screen consists of a touch layer placed on top of a standard display. The touch layer normally includes two transparent electrical layers separated by a small gap. Resistive touchscreens can be used effectively for simple panel controls, such as an automotive GPS panel control or other keypad-replacement applications, or in applications that require gloved use.

Capacitive touch screens are built with a thin layer of conductive material, such as copper or Indium Tin Oxide (ITO), printed onto the underside of the display's insulating outer layer. When a finger touches the screen, a small electrical charge is drawn to the point of contact, which effectively becomes a functioning capacitor. The resulting change in the electrostatic field is then measured to pinpoint where the contact took place. Capacitive touch screens accept “Multi-touch” controls and require less physical force to register a touch. They’re longer-lived than comparable resistive touch screens, making them suitable for high-grade panel controllers.

Advantages of Resistive touch screen:

1. Good resistance

2. Lower price – resistive touch screens are less expensive than capacitive touch screens, which have a more complex technological structure.

3. The versatility of touch – resistive touch screens can react to multiple types of touch. For example, they can register input from gloved or ungloved fingers, but also a fine point of contact as they offer more sensors per inch than capacitive touch screens.

4. Lower sensitivity – a resistive touch screen is less sensitive to touch than a capacitive touch screen. While a high degree of sensitivity to touch can be a good thing, it’s not in environments where accidental stimuli such as liquid spills and splatters can cause them to react unintentionally. That’s why resistive touch screens are widely used in industrial contexts, while the more sensitive capacitive screens are part of consumer products like tablets or smartphones. Drawbacks of resistive touch screens

Advantages of Capacitive touch screens:

1. Easy and flexible operation – a capacitive touch screen is very sensitive to the input and reacts to it immediately.

2. Multi-touch support – it’s possible to press on an icon and enlarge an image on the screen at the same time.

3. Greater display quality – a capacitive touch screen offers a higher degree of contrast and helps users to see the content displayed on the screen more easily.

4. More accurate input – the potential for errors is greatly reduced as there is little or no leeway for the touch screen to interpret input inaccurately.

5. Enhanced durability – a capacitive touch screen can be more durable than a resistive touch screen. That’s because frequently used areas on a capacitive touch screen usually don’t break down and become unresponsive following heavy use. Also, when a capacitive touch screen is scratched, pierced, or cracked, it will continue to operate. The same isn’t true for a resistive touch screen, which usually stops working when its surface is damaged.

In conclusion, determining which type of touchscreen is best for your product is a matter that you should give some consideration to. If you would like some more info on both technologies and how Reshine Display can help you to arrive at the best solution, don’t hesitate to get in touch with Reshine Display.
