How many sensitivity tests does a PCAP touch screen need to go through?

In the laboratory of Xinlilai Optoelectronics, every PCAP touch screen must undergo strict testing before leaving the factory. Behind these rigorous tests is our persistent pursuit of high-quality and sensitive PCAP touch screen.
 

Phase 1: Environmental simulation
Freeze for 48 hours in a -40 ℃ cold storage to test low-temperature touch stability
Simulate coastal climate with a salt spray box and continuously spray for 72 hours to test corrosion resistance
100000 click durability test conducted in a high temperature and high humidity environment at 85 ℃
 

Phase 2: Accuracy Verification
Engineers use laser locators for "millimeter level flaw detection":
1. Project a coordinate grid of 100 × 100 onto the screen
2. Use a 0.3mm stylus to sequentially click on each intersection point of the robotic arm
3. The system records the deviation value between the actual contact point and the theoretical position
Only products that meet the ± 0.05mm error standard can proceed to the next stage.
 

Phase 3: Scene based practical combat
The most interesting test is undoubtedly the "coffee shop simulation": tilting the screen at a 15 degree angle while spraying latte coffee to simulate a splashing scene. The tester needs to wear gloves dipped in cream and quickly slide between the 20 randomly lit dots on the PCAP touch screen. Through 200 sets of such 'stress tests', ensure that the product remains sensitive and reliable in real-world scenarios.
 

The PCAP touch screen that has been tested layer by layer maintains good touch performance. Equipped with waterproof performance, from the precise control of medical equipment to the rainstorm mode of outdoor advertising machines, the sensitivity of the PCAP touch screen is no longer just a parameter, but an instinctive response integrated into the touch screen itself.
