Upgrading from an LVDS to a USB-based display system introduced ESD vulnerabilities, causing failures during 15 kV air discharge testing and resulting in video interruptions and system resets. By optimizing the USB ground path and adding fast-acting TVS protection, the system achieved full compliance, ensuring stable performance and reliable certification readiness.

3M’s APF (Advanced Polarizing Film) is an on-glass reflective polarizer that recycles unused light within the backlight system, boosting brightness, improving energy efficiency, and enabling thinner LCD module designs. Compared to traditional DBEF solutions, APF stands out for its superior wide-angle performance, higher integration, and better suitability for thin, high-efficiency display applications.
