Overview

Once your touch detection is working well, you should perform Calibration. Accuracy during this process is essential to ensure precise touch response. This applies to all DISPLAX sensors.

How to Perform Calibration

1. Launch Displax Connect on the PC connected to your sensor.

2. Navigate to the CALIBRATION tab.

3. Select the screen you want to calibrate, if using multiple screens.
   

4. Leave Normal selected.
   

1. For custom-shaped sensors, see Drag Mode.
   

2. For sensors covering multiple diplays/projections, see Multi Point.

5. Click CALIBRATE.
   
   
   

6. A screen with four calibration targets will appear. For each target:

   • Touch and hold your finger on the center of the target until a full green circle appears and the message “Wait. Processing point data.” is displayed.
     
     
     
     
     

   • Then release and proceed to the next point.

7. Once all points are processed, a message will display "Geometric calibration succeeded." Displax Connect will automatically save the calibration data to the touch controller.
   
   
   

   💡 Since calibration is stored on the touch controller itself, you can connect it to other HID-compliant machines without needing to recalibrate.

8. You may now close Displax Connect.

Why Calibration Matters

• Ensures touch accuracy across the full display area.

• Minimises touch-point drift or offset, especially after installation or physical changes to the screen/sensor.

• Saves on downstream support efforts by providing predictable behaviour across devices.

Best Practices & Tips

• Perform calibration after final physical installation (screen set, air-gap settled, sensor mounted).

• Use a single consistent touch point per calibration target (e.g., a fingertip) and hold steady until completion.

• Avoid recalibrating unless needed (sensor relocated or performance degraded) — the controller retains the calibration profile.

• Do not move your finger whilst touching the target during calibration.
