Good touch performance refers to reliable, continuous, and accurate touch detection across the entire active area of a DISPLAX touch sensor, under normal user interaction conditions.
The guidelines below describe how to verify whether a touch sensor is correctly tuned and performing as expected.
Drag one finger across the screen
Finger should be held approximately 90° relative to the display
Apply minimal finger pressure
Touch detection must remain continuous and uninterrupted
Test across:
Center of the sensor
All borders and edges
Repeat the drag test using two or more fingers
Touch detection must remain active for all fingers
No touch dropouts should occur during movement
Use one hand with four fingers touching
Drag across the entire active area:
Left hand: left → right
Right hand: right → left
Touch detection must remain stable from one side to the other, without interruptions
Larger sensors need increased finger separation to maintain accurate detection
📄 Exact finger distance recommendations are defined in the technical specifications provided with each DISPLAX touch sensor.
A touch sensor is considered well-tuned when it provides:
Continuous drag without loss
Reliable multi-touch detection
Stable performance across center and edges
Correct behavior with minimal pressure
If these conditions are not met, further adjustment of Gain, Threshold, Shield, or Calibration may be required. For further assistance, contact support@displax.com
