5,Frequently Asked Questions (FAQ)
Q1: Will changing the operating system affect touch functionality?
A: No, it will not affect functionality on systems above Windows 7. For Linux, Android, or other OS platforms, corresponding drivers may need to be installed manually.
Q2: What are the optical transmittance and surface hardness of the touch screen?
A:
- Transmittance: 85%–90%
- Surface Hardness: >6H
Q3: What is the minimum border width for silk-printing on PCAP touch screens?
A: We can design the printed cover glass border to match the sensor size exactly, achieving a minimal margin if needed.
Q4: What is the service life of the capacitive touch screen?
A: Mechanically, the touch screen can last over 30 years under normal usage. The actual lifespan depends more on the controller quality and usage conditions.
Q5: What is the burst point rate, and what is its value in typical solutions?
A:
- Burst point rate refers to the scanning frequency of the touch points per second.
- The typical rate in standard solutions is around 150 Hz, ensuring smooth and responsive touch performance.
Q6: How to reduce signal interference with the touch panel?
A:
- Here are some effective methods:
- Ensure proper system grounding
- Place insulation material (e.g. foam) between the touch panel and housing
- Reconnect the USB cable
- Use shielded cables where possible
Q7: What is the correct procedure to test the capacitive touch screen?
A:
- Connect the PCB to the FPC cable.
- Plug the USB cable into the PCB and then into your computer.
- Launch the test software to perform functionality checks.
- After testing, disconnect the USB from the computer.
- Then disconnect the PCB from the FPC and finally detach the USB from the PCB.
