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.
