Abstract
This application provides a high-flexibility layered VR-FPC, including a VR-FPC body, which includes a connecting body, a printed marking line at the mid-frame end, a dynamic bending zone, a connector end at the temple, a steel plate at the connector end, a double-sided adhesive area, a laser-engraved QR code at the connector end, and an EMI area on the back. The dynamic bending zone in this application serves a dynamic bending function. It is a 4-layer FPC composed of 4 FCCLs with a PI of 12.5μm and a Cu of 6μm. The dynamic bending zone is designed with 3 multi-layer boards to form 4 independent single-layer FCCLs, so that the force is distributed among the 4 single-layer FCCLs during bending, achieving a 3g low rebound force and easy installation effect. At the same time, the dynamic bending life is increased from 100,000 times to 300,000 times, greatly improving the bending performance. The printed marking line at the mid-frame end serves an alignment function, and the steel plate at the connector end serves a reinforcing function, which can increase the strength of the connector end at the temple.
