TUV Rheinland proposes a star rating standard for eye comfort for laptop display design
At CES 2025, TÜV Rheinland introduced a star-rating system for eye comfort in laptop displays, and brands including ASUS, Dell, HP, and Lenovo have already joined or obtained this certification. Previously, TÜV Rheinland had already established a star-rating system for eye comfort in desktop monitors; this new standard for laptops also uses a five-star rating system to evaluate laptops' performance in terms of eye comfort. The laptop version of the "eye comfort" certification process mainly tests four technical aspects: "image quality," "ambient light management," "eye protection technology," and "user guide," as well as 15 different test items that significantly affect eye comfort. This version of the certification standard also adds "intelligent brightness control" and "intelligent color temperature control" as bonus features for testing products, thereby making product ratings more accurate. This standard is also the world's first multi-dimensional evaluation system for laptop screen comfort, allowing business users with higher functional requirements, multimedia designers demanding precise image quality, or consumers seeking a comfortable visual experience to choose suitable monitors based on this certification standard. Laptops must achieve a rating of three stars or higher in the test evaluation to obtain certification, representing essential image quality and a satisfactory user experience. Four stars indicate excellent image quality and ambient light management, while five stars signify superior image quality, excellent ambient light management, and a superb user experience.
