BenQ is First on Board for New Trend of Low Blue-light & Flicker-Free Displays

People are spending an increasing amount of time on their computers, mobile phones, tablets, and cameras these days. To protect the eyes of users and prevent injury from long-term exposure to the blue-light wavelengths of LCD monitors, major international manufacturers have begun producing electronic-display devices that emphasize flicker-free, low blue-light features. Among these manufacturers, Taiwan's BenQ has taken the lead by being the first to obtain TÜV Rheinland's flicker-free LCD monitor certification.

Although the ‘flicker' phenomenon usually refers to a very slight difference in contrast brightness and is usually undetectable by the human eye, flicker originating from LEDs, illuminating devices, televisions, or monitors which involve long-term exposure during normal use are considered harmful to the human eye. In the past, 'flicker-free' was a standard consideration for 3D monitors; but the market is now turning to 2D monitors, with those that exhibit the flicker phenomenon considered inferior and incapable of high-definition presentation.

In addition, it is generally believed that long-term exposure to a blue-light environment may cause macular degeneration and be harmful to the eye.  Therefore, the market is developing low-blue-light products that are safer for users, especially gamers, who concentrate on screens for long periods.  “Low-blue-light designs can reduce stress to the human eye, but may result in the distortion of color richness. TÜV Rheinland's low blue-light quality certification aims to balance these two problems,” says Jerry Lin, project manager of BenQ's display devices department.

TÜV Rheinland, a professional certification body for displays, has developed its own specific 2PfG display-quality standards for testing and measurement under different levels of environmental brightness, blue-light strength, wavelength, etc.  For example, displays need to be flicker-free, even in darkrooms and environments with low brightness and lighting. With its measuring equipment and professional team, TÜV Rheinland Taiwan can quickly measure screen reaction times up to 0.1ms, suitable for mobile phones, laptops, tablets, and all-in-one computer-screen product testing.

With extensive experience in the testing and certification of display products, TÜV Rheinland  can help companies further improve the image quality of their displays.
