Material specifications for the Magicmoon 15.6-inch Privacy Filter confirm a PET-based multi-layer substrate designed as a passive optical device. It utilizes micro-louver technology to restrict the viewing angle to 30 degrees from the center. Forensic analysis indicates the anti-glare coating achieves an 85% diffusion of specular reflections. The physical dimensions are fixed at 344mm by 194mm, optimized for 16:9 aspect ratio panels. Standardized testing protocols show a luminance attenuation ranging from 15% to 20% due to the density of the louvered layers.
The unit provides a 60-degree total viewing cone and is reversible to accommodate different ambient lighting conditions. The matte side is designated for glare reduction, while the glossy side is intended for increased color clarity. Performance metrics indicate that the film also provides a physical barrier for the Thin-Film Transistor (TFT) layers against micro-abrasions. Mounting is achieved through clear adhesive tabs or slide-on plastic clips, as the unit lacks integrated magnetic components.
- Visual cone: 60 degrees total (±30 degrees).
- Substrate: Multi-layer PET.
- Mounting options: Adhesive strips, slide-on tabs.
Technical limitations include a potential "screen door effect" when applied to high-DPI or 4K displays and a reduction in capacitive touch sensitivity. Reliability is dependent on surface preparation; technical documentation suggests using 70% isopropyl alcohol to remove oils before application to prevent adhesive failure during thermal cycling from the laptop’s heat output.
Users operating with 15.6-inch hardware who prefer a non-adhesive, hanging installation may consider the J J-Dream Hanging Shield to avoid residue.
This filter is an architectural component of the privacy screens classification, providing analog data protection.
