Add a privacy glass layer to the 11.6-inch display used by Lenovo 300e Gen 3 notebooks. CELLAIRIS 11-0078584 is matched to the system's 16:9 screen format, providing display coverage without selecting a generic laptop-size protector. Its privacy treatment helps restrict viewing from side positions, making the screen more suitable for work performed around nearby users. The glass construction provides a screen-protector option for organizations maintaining Lenovo 300e Gen 3 systems in education, shared-device, and mobile-user environments. Compatibility with the specific notebook model matters because screen protectors must align with the actual display dimensions and aspect ratio rather than only the diagonal screen measurement. This protector is intended for the 11.6-inch Lenovo 300e Gen 3 display. Choose this version where both screen coverage and privacy viewing control are required. The privacy feature distinguishes it from a standard clear glass protector, while its Lenovo 300e Gen 3 compatibility separates it from protectors intended for other laptop display sizes. It is a focused accessory for protecting the display area and reducing off-axis visibility during routine notebook use.
