With the emergence of light-emitting diodes (LEDs), organic light emitting diodes (OLEDs) technology, QLED and micro LED, and its increasing use in electronic display products, public interest and concern about blue light has increased. Additionally, with daily screen time continuing to increase and close-up use of devices occurring at all times during the day, users are being exposed to increasing amounts of high-energy visible (HEV) blue light from their devices.
The display industry has developed two different methods to achieve the blue light reduction: a software solution and a hardware solution.
The hardware solution was developed to control the blue light range emission. Instead of reducing the total blue range, the selected range reduction does not impact CCT and display color. It exposes users to less blue light emission while letting them enjoy good color on the display.
TÜV Rheinland has tested this product in order to ascertain the product can offer an effective reduction of hazardous blue light by offering a hardware solution that can filter or reduce the blue light range of the display spectrum.
TÜV Rheinland has defined a catalogue of tests, which establishes the minimum standards for the low blue light content characteristic according to the product and manufacturer's information.
This standard focuses on the blue light ratio and category and the color space coverage.
The testing criteria are based on TÜV Rheinland’s research and development, as well as industry standards, exceeding the industry standards.
The blue light content was measured and evaluated in the laboratory using spectro-radiometers.
The keyword " Low Blue Light (Hardware Solution)" confirms that the product satisfies TÜV Rheinland's test criteria.
