Gain & Threshold Adjustment in Displax Connect

Gain and Threshold are settings used to fine-tune touch performance:


  • Gain: Adjusts the signal strength sent from the touch controller to the touch sensor.

    • Use a higher Gain for thicker glass or larger sensors.

  • Threshold: Sets the sensitivity level for what is recognized as a touch.

How to Adjust Gain and Threshold

  1. Set Gain to the lowest value (0) and wait 2 seconds.

    • A “Do not touch” message will appear during this time.

  2. Adjust Threshold:

    • Touch and drag on the display.

    • Increase the Threshold gradually until touch performance is smooth and continuous, especially when dragging across the center and edges of the screen.

    • If the drag color changes or touch stops, touch detection has been lost.

  3. If Threshold reaches the maximum value (50) without good performance, increase the Gain by 1 and repeat step 2.

  4. Repeat steps 2 and 3 until you achieve a good touch performance.


What is Good Touch Performance?

✅ Continuous and uninterrupted touch tracking across the entire touch area.
✅ No touch loss during dragging, including at the screen borders.

⚠️ Note: If good performance is achieved but false touches still occur, review the Shield feature.
