Filtro de privacidade sem moldura 3M BP140W9B 14" resistente a riscos

The 3M BP140W9B frameless display privacy filter is designed for 14-inch netbooks to protect on-screen data from side glances while preserving image clarity for the primary user. This slim, black privacy filter offers scratch resistance and anti-glare properties, transmitting approximately 85% of light and narrowing the visible angle to 60 degrees to reduce viewing from oblique positions.

Advantages

The frameless design keeps the filter lightweight and minimally intrusive while providing screen protection against scratches. With an 85% light transmission rate and anti-glare surface, the filter maintains comfortable viewing for the user while limiting visibility for others. The 60-degree privacy angle helps prevent visual hacking without altering the device form factor.

Suitable for

• 14-inch netbooks and similarly sized laptops
• Mobile work in public spaces (cafés, trains, airports)
• Office environments where screen confidentiality is required
