Infrared (IR) touch technology is susceptible to interference from strong light sources (like sunlight). Avoid placing these devices in high-brightness environments.


  1. Avoid Direct Light Sources: Do not install [IR Touch] devices near windows, under skylights, or outdoors. The IR spectrum in sunlight can "overwhelm" the sensors.

  2. Control Ambient Light: If the room is too bright, use [Blackout Curtains], blinds, or UV-filtering films to block external infrared interference.

  3. Bezel Maintenance: Regularly clean the [Inner Edges of the Bezel]. Dust buildup combined with bright light causes signal refraction, leading to touch drift or "Ghost Touches."

  4. Environment Diagnostic: To test, turn off overhead lights or cover nearby windows. If touch functionality returns to normal, the issue is environmental, not a hardware defect.


Notes:

  • Tip: If the installation site requires high-brightness placement, consider switching to models with PCAP (Projective Capacitive) touch technology.

  • Note: Some IR models have an "Ambient Light Compensation" setting; check the OSD menu to enable this feature if available.
