1Object-generated harmful factors
If holes are formed in the LED screen to reduce sound blockage, then sound quality and volume are improved, but data leakage risk increases due to failure to meet FIPS requirements
Solution Approach 1:
The invention divides the screen structure into multiple segments: LED light-emitting units for visual display, sound through-channels for audio transmission, and conductive layers for electromagnetic shielding. This segmentation allows each component to fulfill its specific function without compromising overall performance, enabling sound to pass through while maintaining data security through proper conductive layer design
Solution Approach 2:
The conductive layer acts as an intermediary element between the sound through-channels and the external environment. It provides electromagnetic shielding to prevent signal leakage while allowing sound waves to pass through, thus mediating between the conflicting requirements of sound transmission and data security
