Black Edge Invisible Shield 23.8 Inch Removable Laptop Privacy Screen Filter
◎ What is Privacy Filter?
A privacy filter, also called a privacy screen or a monitor filter, is designed to protect a laptop or the screen of a desktop monitor from prying eyes and shoulder surfers. They decrease the viewing angle, allowing only the person sitting immediately in front of the screen, typically the user, to view the contents of the screen. Privacy filters fit directly above a monitor screen and attach securely in front. Privacy filters also reduce radiation and glare generated from LCD and CRT computer monitor displays.
