TÜV SÜD Japan, local subsidiary of TÜV SÜD, a globally acclaimed German safety and quality expert, launched certification service for Blue Light Ratio in July 2020. This service provides a certification mark including the percentage of the Blue Light Ratio for PC, televisions, smartphones, and other devices that have been tested according to international standards.
There has been a remarkable shift from paper media to displays, and people are becoming increasingly concerned about blue light. Blue light is said to affect eyestrain, and many companies are proposing measures for the light emitting side (e.g., attaching filters and low-blue light mode to devices) and the light receiving side (e.g., blue light-cutting glasses). However, the abundance of various anti-blue light products leads to difficulties for consumers to distinguish good products.
To address this issue, TÜV SÜD Japan has launched a service to test and certify the Blue Light Ratio* of products using LED backlight, LCD displays or LED displays. This service, which was launched in September 2007 at a laboratory in TÜV SÜD Taiwan, provides an objective assessment of product safety based on multiple international IEC/EN standards.
The main feature of this service is the certification mark showing the percentage of Blue Light Ratio (see “Certification Mark Features” below). The minimum requirement of Blue Light Ratio of 25 % or less, and the ratio is detailed in 5 % increments (10 % / 15 % / 20 % / 25 %). This allows equipment manufacturers to specifically indicate the blue light percentage of their products and allows consumers to identify it. TÜV SÜD Japan will continue to provide trust along with services that meet the needs of the market.
