Threshold

Threshold

Overview

The Threshold setting in DISPLAX Service defines the sensitivity level used to determine what is considered a valid touch input. Adjusting the Threshold helps improve touch accuracy, stability, and reliability across different sensor sizes, glass thicknesses, and installation conditions.

Threshold tuning is commonly performed together with Gain adjustments.

Check the Current Threshold Value

To view the current Threshold value on a local device, run:

displaxservice -a 127.0.0.1 --thni

This command returns the active Threshold value.

Set the Threshold Value

To change the Threshold value, specify a numeric value.

Example: Set Threshold to 30

displaxservice -a 127.0.0.1 --thni 30

The new Threshold value will be applied to the connected touch controller.

What Threshold Controls

  • Higher Threshold values increase sensitivity but may cause false touches

  • Lower Threshold values reduce sensitivity and improve noise immunity

The correct Threshold value depends on:

  • Touch sensor size

  • Glass thickness

  • Installation environment

  • Level of electromagnetic interference

Best Practices

  • Start with a lower Gain and gradually increase the Threshold.

  • Test dragging across the entire sensor, including edges and corners.

  • Increase Threshold until touch tracking is continuous and stable;

    • if this is not achieved with Threshold at maximum value of 50, increase the Gain by 1 value, and start again with Threshold from 0

  • Avoid excessive Threshold values that make the sensor hyper-sensitive.
