1. What is the function of EMI shielding film?
EMI shielding film is used to suppress electromagnetic interference (EMI) and electromagnetic radiation. It prevents electromagnetic leakage, protects information security, and avoids data theft or monitoring. It also enhances the product’s electrostatic resistance.
2. Where is the shielding film applied in a display module?
The shielding film is placed between the display and the touch panel using a full lamination process.
3. What are the common application scenarios for shielding film?
● Defense & Military
● Automotive electronics
● Medical equipment
● Communication devices
4. What are the material types and performance of shielding films?
Different materials are selected based on application scenarios. The main categories include:
材料类型 | 屏蔽效果 | 显示效果 | 透过率 |
纳米银材料 | >27dB | 无颗粒感 | 80% |
不规则金属网屏蔽膜 | >40dB | 有少量颗粒感 | 75% |
4K 屏蔽膜（颗粒纹理） | >45dB | 可见摩尔纹 | 75% |
