Touch Screen Tap-and-Scratch Durability Tester
The Touch Screen Tap-and-Scratch Durability Tester is a dedicated life-cycle testing system for evaluating the tapping and scratching durability of mobile phone touch screens and similar display surfaces. The instrument simulates real user interaction by repeatedly tapping or sliding a stylus (or equivalent rubber tip) across the screen under controlled force, speed, and trajectory. By presetting test cycles and motion paths, the system assesses the screen’s resistance to wear, scratching, and functional degradation caused by long-term touch operations.

Test Procedures
Specimen installation
Fix the touch screen or display module securely on the test fixture at each station.
Ensure the test surface is flat, clean, and properly aligned with the motion path.
Parameter setting
Set tapping force (100–500 gf) via the cylinder control.
Select movement speed (0–300 mm/s).
Choose motion pattern (rectangle, triangle, straight line, or diagonal).
Input required test cycles on the counter.
Running the test
Start the system; the stylus performs programmed tapping or sliding movements.
The system automatically records cumulative cycles and continues until completion.
Test completion
The machine stops automatically when the preset cycles are reached.
Inspect the screen for scratches, wear, or functional degradation.
Maintenance Information
Keep the stylus tip clean and replace it if worn or damaged.
Regularly check the cylinder pressure and air supply stability.
Clean guide rails and motion components to avoid dust interference.
Avoid overloading beyond specified force range.
Perform periodic calibration of movement speed and force output.
