1. ACCURATE SIZE: The private computer screen perfectly fits 21.5 inch computers, with an aspect ratio of 16:9, 475mm wide and 268mm high. Unique double-sided structure, shiny has better anti-peeping effect.
2. : The frosted is made of premium technology, which reduces glare by more than 90 degrees and softens the light, so you won't feel strong reflections in bright light environments.
3. ANTI BLUE LIGHT: The computer private filter is made of imported optical material, which can reduce 92% of blue light and 98% of UV rays, filtering out all harmful light emitted by the screen and protecting your eyes.
4. HIGH DEFINITION: This computer private filter protective film has a highly transparent reinforced built-in protective layer, which does not present high-definition image quality, but also protects your screen from scratches.
5. HIGHER SAFETY: With the private filter of the computer screen, the data on the screen is visible to sitting in front of the screen, making the screen appear dark when viewed from an angle (30° for each angle, 60° for both).
