This article provides some possible causes of interference on PCAP touchscreens

Capacitive touch screens rely on changes in capacitance to detect touch inputs. There are a few factors that can interfere with their performance. Some of these may include:

1. Conductive materials: Conductive materials such as metal or liquids can interfere with capacitive touch screens by disrupting the electrical field that the touch screen relies on to detect touch inputs.

2. Electromagnetic interference: Electromagnetic fields from devices such as cell phones, radios, or other electronic devices can interfere with the capacitive touch screen's electrical field and cause false touch inputs or decreased sensitivity.

3. Protective coverings: Some protective coverings or cases for mobile devices can interfere with the touch screen's ability to detect touch inputs by adding an extra layer of material between the user's finger and the touch screen.

4. Dirt and moisture: Dirt, oil, and moisture on the touch screen surface can interfere with the capacitance and reduce the touch screen's sensitivity.

5. Power source: If the touch screen's power source is not consistent, it can affect the touch screen's ability to accurately detect touch inputs.

If you experience interference in your PCAP touchscreen, check the list above for anything that may be causing it. Move the Elo device to a different location or remove the equipment causing the interference.
