Μεμβράνη απορρήτου χωρίς πλαίσιο DICOTA D80121-4AD 27,9 cm 2H

The DICOTA frameless 4-way privacy filter for 27.9 cm (11") displays reduces side visibility to protect personal and confidential information in public places such as libraries, open-plan offices, airports and trains. The matte, frameless filter limits the viewing angle to ±30° while allowing approximately 50% light transmission for usable screen brightness. A silicone layer enables easy, bubble-free application and residue-free removal; the filter also reduces reflections, limits fingerprints and offers scratch resistance with a 2H hardness rating.

Advantages

This privacy filter darkens the screen from the right, left, top and bottom at viewing angles outside ±30°, helping to keep on-screen content private. The frameless design and matte finish reduce reflections and glare. A special silicone adhesive allows straightforward, bubble-free attachment and clean removal without leaving residue. The filter is lightweight (about 100 g) and provides surface protection against scratches and smudges.

Suitable for

• Tablet users who work in public spaces
• People who handle confidential or personal data on a 27.9 cm (11") display
• Commuters using tablets on trains or planes

How to use

Clean the tablet screen thoroughly to remove dust and grease. Peel off the protective film from the silicone layer, align the frameless filter with the display edges and press gently from the centre outward to apply without bubbles. If small bubbles remain, smooth them toward the edges. To remove, lift a corner and peel the filter off slowly; the silicone layer is designed to leave no adhesive residue.

Recommendations

Use the privacy filter when working in public or shared environments where on-screen information should remain confidential. Avoid prolonged exposure to heat sources and store the filter flat when not in use to preserve its shape and adhesive properties.
