Here are five different types of touchscreen technology that are currently making huge waves in the tech industry:
Resistive Touchscreen
For several reasons, resistive touchscreens are the most commonly used touchscreens. They are inexpensive to produce, highly durable, and possess a high degree of versatility. They can be used with almost any instrument, such as your fingers, stylus pens, the edge of a credit card, and so on. You can even use them while wearing gloves. Resistive touchscreens are made up of a carefully crafted multi-layered infrastructure glass and a protective film screen, both of which are shielded by a metallic layer, as well as a tiny gap that allows for precise point of contact recognition. When you touch the outer layer, the two layers come together at that precise point.
Capacitive Touchscreen
Capacitive touchscreens are not as durable or versatile as resistive touchscreens and can only be used in a few industries. They are more susceptible to environmental damage and cannot be used with different objects. They can only respond to the touch of a bare finger because they rely on conductivity produced by the human body. They are, however, ideal for indoor office or retail use. There are two types of capacitive touchscreens:
Surface capacitive touchscreens have an additional protective layer that’s scratch, drop, dirt, and liquid-resistant. These are ideal for the retail or restaurant industry because they have quick response and dragging capabilities.
Projected capacitive touchscreens are also ideal for indoor use because they’re equipped with an external layer of tempered glass, making them resistant to cracks, defacement, and rough usage.

Surface Acoustic Wave Touchscreen
Surface Acoustic Wave (SAW) touchscreens can be used with almost any instrument because they do not rely on conductivity to function. This perimeter-based technology detects points of contact using ultrasonic waves. They have exceptional visual abilities due to the lack of a filmy protective layer. Unfortunately, this makes SAW touchscreens more vulnerable to damage from outside sources.
Infrared and Optical Touchscreens
Infrared and optical touchscreens are also based on the perimeter. Infrared light beams are used in infrared touchscreens. LED sensors on one side of the screen interact with light sensors on the other until they are interrupted by a touch at a point of contact. Optical touchscreens, like infrared touchscreens, use infrared lights, but their setup is slightly different. Within the screen's structure, two cameras detect touch and calculate the precise point of contact.
