What is a Resistive Touch Screen?
In simple terms, a Resistive Touch Screen is a touch-sensitive computer display that responds by applying pressure. It’s made from two resistive-coated transparent sheets that are separated by a small air gap. When contact is made to the surface of the touchscreen, these two sheets are pressed together. Each sheet has horizontal and vertical lines that register the precise location of the touch. Because the touchscreen senses input from contact with nearly any object (finger, stylus/pen, palm, etc.) resistive touchscreens are a type of passive technology. All this means is that the Resistive Touch Screens do have an internal power source, and so rely on electromagnetic energy transmitted from an RFID reader.
What are the different types of Resistive Touch Screens?
There are two types of resistive touch screens:
- A Digital Resistive touch screen works by applying pressure to the screen, and can be operated by pressing a finger, a stylus or even a fingernail onto the surface. This type of touch screen works on an X-Y matrix.
- Analog touch screens are designed for pen recognition applications and can offer higher resolutions.
What are the advantages & drawbacks of Resistive Touch Screens?
Advantages of using resistive touch screens:
- Very cost effective
- Easy to integrate
- Can be operated with numerous touch signals
- Resistant to dust, moisture and humidity
Drawbacks of using resistive touch screens compared to other technologies like capacitive touch screens:
- Can be prone to damage as they require more of a physical contact with the touch layer to detect an input
- Limited contrast and do not support multi-touch.
What is a Capacitive Touch Screen?
Capacitive Touch Screen panels look similar to digital panels to the user, but they do not require pressure to operate. A simple touch of the finger draws a small amount of current creating a voltage drop, therefore, it does not need as much physical pressure on the screen. This can help ensure the touch screen’s longevity. Since both layers of a Capacitive Touch Screen are glass, it allows for higher resolution and can detect multi-touch. Generally, Capacitive Touch Screens are more expensive due to their complex structure.
The differences between the three types of touch screens can be subtle, but they are important in determining which touchscreen is best for you. Whether you need a Digital Resistive, Analog Resistive, or Capacitive touch screen, RSP has the versatility to provide the best option for your company.
