HONG KONG, June 20, 2014 /PRNewswire/ -- People are spending an increasing amount of time on their computers, mobile phones, tablets and cameras these days. In order to protect our eyes and to prevent them from injury from long-term exposure to the blue-light wavelengths of LCD monitors, electronic-display devices that emphasize flicker-free, low blue-light features have quietly emerged as the new mainstream in recent years. Major international manufacturers have gone into the production of such displays, among which BenQ gained the lead by being the first to obtain TUV Rheinland's first flicker-free LCD monitor certificate.
Although the "flicker" phenomenon usually refers to a very slight difference in contrast brightness and usually is undetectable to the human eye, flicker originating from LED, illuminating devices, televisions, or monitors which require long-term exposure during normal use are considered harmful to the human eye. In the past, flicker-free was the standard consideration for 3D monitors, but the market now is turning to 2D monitors, with those that exhibit the flicker phenomenon considered inferior products and incapable of high-definition presentation.
In addition, it is generally thought that long-term exposure to blue-light environments may cause macular degeneration and be harmful effect to the human eye. Therefore, the market is developing low blue-light products safer for users, especially for gamers, who must 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. TUV Rheinland's low blue-light quality certification aims to balance the two problems," says Jerry Lin, project manager of the display devices department.
TUV Rheinland is a professional and experienced certification body for displays. We have developed our specific 2PfG display-quality standards for the 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 our measuring equipment and professional team, TUV Rheinland can quickly measure screen reaction times up to 0.1ms, suitable for mobile phones, laptops, tablets, and all-in-one computer-screen product testing.
TUV Rheinland has extensive experience in the testing and certification of display products, and can assist companies in further improving the image quality of their displays.
