Stroboscopic effect refers to the periodic fluctuation of screen brightness, which is particularly obvious in OLED screens with low-brightness PWM dimming. Some sensitive people may experience reactions such as eye strain and headache. This is a real issue, but its solution lies in the screen dimming method, not the film.
It should be truthfully stated that no film can change the dimming method of the screen, and the "anti-flicker film" lacks a physical basis. This special topic provides system setup paths and purchasing suggestions for sensitive groups.
