TÜV Rheinland Releases the White Paper on Perceptual Color Volume and Issues Perceptual Color Volume Certification to BOE Laptop Display Module
Greater China | 03 April, 2024
On April 1, TÜV Rheinland Greater China, an international independent third-party testing, inspection, and certification organization, attended the 2024 International Conference on Display Technology (ICDT) held in Hefei, officially released the White Paper on Perceptual Color Volume and issued the Perceptual Color Volume Certification to the BOE laptop display module (model: NE160QDM-NM7).
TÜV Rheinland released the White Paper on Perceptual Color Volume
Color volume represents the range of colors reproducible by a display, and is mainly affected by three factors, namely color reproduction technology or display media, viewing conditions, and color space, among which the latter two constitute a color appearance model (CAM). With the continuous advancement of the display technology, the limitations of color volume evaluation on traditional display products are becoming increasingly prominent, as it is only a simplified model of the human eye's color perception and cannot fully reflect the human eye's color perception under different brightnesses.
The White Paper on Perceptual Color Volume released by TÜV Rheinland provides an in-depth analysis of the shortcomings in traditional color volume evaluation and emphasizes the importance of color volume in improving the color performance and user experience of display products. The White Paper systematically proposes an indicator for measuring, calculating and evaluating the 3D perceptual color volume of display devices, aiming to provide a more scientific color evaluation method for the display industry, promote display technology progress and industrial upgrading, and bring consumers richer and more realistic visual experience.
"TÜV Rheinland collaborated with the Color Engineering Laboratory of Zhejiang University to conduct a full year of research on the color volume measurement and calculation of display products, and has developed the perceptual color volume evaluation standard based on the latest CAM16 color appearance model from the International Commission on illumination (Commission Internationale de L'Eclairage, CIE). We will work with global display industry partners to promote this standard and gradually establish a more scientific color evaluation system." said Liu Xiqiang, Global Technical Director of Display Products at TÜV Rheinland.
Compared with the widely used two-dimensional color volume coverage based on the CIE 1931 standard colorimetric system, the perceputal color volume 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; 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.
The BOE laptop display module obtained the Perceptual Color Volume Certificate
During the same period, TÜV Rheinland issued the Perceptual Color Volume Certificate to the BOE laptop display module. After testing and evaluation, this laptop features over 105% color volume coverage and an average color accuracy of ∆E2000<3 for 4096 colors. This means that the screen can reproduce almost all colors within the DCI-P3 color volume range, allowing it to pass the TÜV Rheinland’s Perceptual Color Volume Certification with excellent color performance.
“BOE continues to develop high-quality color volume technology in the display industry and has accumulated a number of industry-leading technologies in terms of laptop screen such as UHD image quality, excellent color, healthy eye care and so on, bringing excellent visual enjoyment and user experience to the majority of users. The color volume certification project launched in conjunction with TÜV Rheinland aims to fit the overall color perception of the human eye, and truly depict the product's color reproduction capabilities in the full brightness range based on the users' visual experience. In the future, BOE will continue to adhere to the "Empower IoT with Display" strategy, empower thousands of application scenarios with innovative technology, and open up new vision of wisdom.” said Zhang Dayu, Notebook Customer Development Manager of BOE LCD Product Development Center.
The unified color volume model can better adapt to the human eye's overall perception of color, including brightness, hue and saturation, and can also more objectively manifest the color uniformity of the product. A color volume will better manage the color calibration of the product and finely control key indicators such as uniformity and tone consistency. In the future, TÜV Rheinland will further provide technical solutions for quality evaluation and user experience issues in industrial development through industry-university-research cooperation, assist enterprises in product research and development and technological innovation, and provide professional guidance for consumers in purchasing high-quality products.
