TÜV Rheinland issued its “perceptual color volume” certification to the new Lenovo Yoga Pro 9i laptop, which was unveiled at the Consumer Electronics Show in Las Vegas earlier this month.
During testing the Yoga Pro’s Mini LED backlit LCD screen was able to reproduce almost all colors within the DCI-P3 color volume range.
“When it comes to display innovation, we know from customer feedback that perceptual color volume is an important factor,” said Zhaochun Ma, vice president and general manager of consumer and SMB at the Notebook Development Center in Lenovo’s Intelligent Devices Group. “That’s why we made sure the new Lenovo Yoga Pro 9i laptop offers eye safety for consumers under different brightness levels while providing richer, more realistic color reproduction.”
TÜV Rheinland’s perceptual color volume evaluation standard is based on the latest CAM16 color appearance model from the International Commission on Illumination (CIE).
The CAM16-based standard takes into consideration the color adaptation and brightness adaptation characteristics of the human eye and can scientifically describe the true three-dimensional color volume size of display products relative to the human eye’s real perception of color, said TÜV.
TÜV Rheinland said it conducted a full year of research on the color volume measurement of display products, before concluding that the CIE CAM16 uniform color volume was currently the most ideal color appearance model.
“By comparing the overlap rate between the measured color volume of a product and the DCI-P3 color volume with equivalent peak brightness in a three-dimensional space, the actual percentage of the product’s standard DCI-P3 color volume reproduction can be accurately measured,” TÜV Rheinland said in a press statement.
