Capacitive touch screen vs. resistive touch screen

Capacitive touch screen
Capacitive touchscreen technology is our most common method of interaction. This is the type of display we see on smartphone, laptop and tablet screens.
Capacitive screens are composed of multiple layers of glass and plastic coated with a conductive material such as indium tin oxide or copper. This conductive material reacts when it comes into contact with another electrical conductor, such as a bare finger. When you touch a screen, a circuit forms where your finger touches, changing the charge at that location.
Capacitive touch screens generally have a brighter, clearer appearance and are much more responsive than resistive touch screens. We tend to see capacitive touch screens in more modern technology like smartphones and tablets. They allow us to experience high-quality images that mimic reality.
With social media so integrated into our lives, we are constantly sharing and experiencing life through our devices. The latest capacitive touch screens make it possible to interact with high-quality applications easily.

Resistive touch screen
Resistive touch screens work just as their name implies – they have touch resistance. A layer of glass or hard plastic is covered by a resistive metal layer that conducts electrical charges. The two are separated by a spacer in the screen, so when your finger presses hard against the protective plastic layer, the two layers come into contact, changing the charge at that location, prompting the software to respond.
Resistive screens are not as bright as capacitive screens because their thick blue and yellow layers make their interface look darker than capacitive screens. You’ll often see resistive screens used on ATMs, checkout counters, and POS (point-of-sale) terminals. They tend to be more durable and more affordable than capacitive screens due to their hard plastic exterior.
Each screen has pros and cons that make it a better choice for certain applications. Capacitive screens offer greater flexibility in functionality, as resistive screens cannot register multiple touch points simultaneously.
Think about when you zoom in on your smartphone – you use two fingers on different receivers to zoom in on the image. Resistive touch screens get confused when you try to apply multiple points to them because their technology relies on identifying pressure at specific locations.

Advantages of capacitive touch screens

– Fast, responsive touch response and excellent dragging performance
– Multi-touch supports gestures such as pinch to zoom, etc.
– High durability
– Excellent optical clarity and color fidelity
– Stable performance, no drift – No calibration required
– Only recognizes touches from a finger or capacitive stylus
– Touch performance is generally unaffected by daily use and accidents such as dirt, dust, condensation, liquid spills, contaminants or cleaning solutions.

shortcoming
– Projected capacitive technology is more expensive than resistive technology
– High levels of electronic noise can reduce accuracy.
– Only recognizes touches from a finger or capacitive stylus
– Conductive smudges and similar interference on the panel surface may affect performance. This type of conductive stain mainly comes from sticky or sweaty fingertips.

Application areas
– Point of sale terminals (POS)
– Retail kiosks
– game entertainment
– hotel
– Corporate offices and meeting rooms
