The J J-Dream Hanging Privacy Shield is a mechanical optical component constructed from Grade-A acrylic. Unlike PET films, this 15.6-inch shield utilizes a hanging lip for attachment, creating a slight air gap between the laptop panel and the filter. This architecture facilitates thermal management by preventing heat trapping on high-brightness displays. Material analysis confirms a multi-layer stack with high-precision micro-louver alignment, providing a 60-degree total privacy cutoff.
Technical specifications indicate a 9H surface hardness rating, which serves as a physical barrier against keyboard imprinting and micro-scratches. The blue-light filtration coating is verified for attenuation up to the 450nm spectrum. Because the unit is non-adhesive, it leaves no chemical residue on the display's oleophobic coating. The 16:9 aspect ratio is strictly enforced by the acrylic mold, making it incompatible with 16:10 or 3:2 panels.
- Substrate material: Grade-A Acrylic.
- Surface hardness: 9H.
- Mounting mechanism: Bezel-hanging lip.
Performance limitations include a portability barrier, as the laptop lid cannot be closed while the shield is attached. The air gap between the panel and the shield may also catch reflections from overhead lighting in specific office environments. Technical documentation suggests verifying bezel thickness to ensure the hanging lip sits securely on the host hardware.
For users who require a more portable 15.6-inch solution that allows the laptop to close, the Peslv Magnetic 15.6-inch Filter provides a lower-profile alternative.
This unit is classified as a heavy-duty variant within the privacy screens hardware family.
