The 3M ThinkPad Yoga Landscape Privacy Filter from Lenovo utilizes patented 3M Microlouver privacy technology, ensuring that the screen can only be viewed by individuals directly in front of it. Bystanders or those viewing the display from an angle will see a blank, dark screen. As identity theft becomes an increasing concern and laws regarding information disclosure grow stricter, the need to protect confidential data is particularly critical. Thanks to unique attachment systems, the privacy filter remains in place even when the laptop is closed. Reversible for glossy or matte screen finishes, it reduces glare when the matte side is facing you. Easy to attach and remove, it protects the LCD display from scratches.
