TV Screen Protector For 39-40 Inch Displays

This anti-blue light filter panel measures 35.6 by 21.3 inches and is designed to fit LCD, LED, 4K OLED and QLED televisions between 39 and 40 inches. It blocks 60% of harmful blue light between 380 and 480 nanometres and 100% of UV light while maintaining full colour transparency. The panel helps reduce eye strain, fatigue and sleep disruption caused by prolonged screen exposure.

Check Screen Dimensions And Mounting Before Ordering

Measure the visible display area of your television to confirm it matches the 35.6 by 21.3 inch panel size. The filter attaches using supplied Velcro strips and a security strap that wraps around the TV stand or wall mount. Ensure your TV design allows access to the rear for the strap and that the bezel does not obstruct the panel edges.

Ideal For Office Workers And Evening Viewers

This protector suits anyone who spends long hours in front of a large screen and wants to reduce blue light exposure without distorting picture quality. It is not for users whose TV dimensions fall outside the specified range or who cannot accommodate the strap mounting method. Buyers needing a filter for smaller monitors or different aspect ratios should look at other sizes.
