How to choose Capacitive touch monitors and infrared touch monitors

In the world of touchscreens and touch monitors, two popular touch technologies stand out: capacitive and infrared. Understanding their differences can help you make the right choice for your specific applications.​

 Touch Technology Basics​

Capacitive touchscreens rely on the electrical conductivity of the human body. When a finger touches the screen, it disrupts the electrostatic field, and the monitor detects the change to register the touch location. This technology offers high – precision touch function, allowing for smooth interactions like pinch – to – zoom and multi – touch gestures.​

On the other hand, infrared touch monitors use an array of infrared LEDs and photodiodes around the edges of the screen. When an object, such as a finger or a stylus, interrupts the infrared beams, the monitor calculates the touch point. It doesn’t depend on electrical conductivity, so it can be used with gloves or other non – conductive objects.​

Touch Function and User Experience​

Capacitive touchscreens provide a very responsive touch function. The touch is extremely sensitive, making it feel natural for users. However, it may not work well with wet hands or if the screen has a layer of moisture on it.​

Infrared touch monitors, while generally responsive, may not offer the same level of sensitivity as capacitive ones in some cases. But their ability to work with various objects gives them an edge in certain scenarios. For example, in industrial settings where workers may need to use the touch monitor while wearing gloves, infrared technology is more suitable.​

Applications​

Capacitive touch monitors are widely used in consumer electronics like smartphones, tablets, and some high – end touch – enabled laptops. In business, they are popular in areas where a sleek and modern look is desired, such as in retail point – of – sale systems for a more consumer – friendly interface.

Infrared touch monitors find their niche in industrial applications, outdoor kiosks, and medical equipment. Their durability and ability to work in harsh environments, including those with moisture or when used with non – standard input devices, make them a preferred choice in these fields.

In conclusion, both capacitive and infrared touch technologies have their own strengths, and the choice between them depends on the specific requirements of the touch application.
