Blue light with wavelengths under 455 nm could affect vision. Eye-Care solution is designed for eyesight protection: the display provides proprietary eye-care technology with ultra-low blue light emission and no visible or invisible flicker within the range of 0-3000Hz, preventing eyestrain caused by extended sessions in front of a display. In addition, advanced anti-glare screen treatment minimizes distracting reflections and glare for optimal productivity and comfort.

• To meet the Low Blue Light TÜV certification, the display settings should be:
  • Picture mode: Standard
  • Color temperature: Normal
• The default settings of the display meets the Flicker-Free & Flicker-Reduced TÜV certification.

Flicker-Free and Flicker-Reduced is improved from the power circuit. Flicker-Free uses DC power technology for linear dimming or adjusts the PWM frequency to meet safer specifications. Flicker-Reduced only uses PWM and adjusts the PWM frequency to meet the criterion.

With this technology, the light source of the LED backlight module either avoid or reduce screen flicker to reduce eye fatigue. BenQ’s non-flicker technology has also been certified by TÜV Rheinland, which shows BenQ’s commitment in safeguarding vision health of consumers.

The BenQ Board Essential RE04  touchscreen is treated with nano-ionic silver, an antimicrobial agent that prevents the spread of germs. The RE04 screen ensures 99.9% protection against common germs, as certified by TÜV.
