Do computer monitors flicker? Yes, some of the monitor screens can flicker up to 250 times per second, so 8 hours in front of a monitor can expose you to 5.8 million flickers on your screen, which cause the pupil and ciliary muscles in the eye to be stimulated and act continuously. Over exposure to this flickering can lead to eye fatigue, headaches, and blurred vision.
Generally, the flickering of the computer screen is mainly due to the LED backlight used in the LCD panel. The backlight of monitors without Flicker-Free technology is driven by "pulse width modulation" (PWM) which turns the backlight on and off rapidly to adjust the screen brightness.
The BenQ research team established an expert panel of ophthalmologists to determine how to resolve distracting flickers. The problem was solved when BenQ introduced a DC dimming backlight technology to monitors, and released the world first Flicker-free monitor in the world in 2011.
BenQ’s Flicker-free technology, certified by international TÜV Rheinland, eliminates flicker. While you’re looking at your display, your BenQ monitor is looking after your eyes.
