TÜV Rheinland Collaborates with TCL and Nanosys on Display Technologies, Unveils Latest Achievements at CES

From January 6 to 7, 2026 (local time), during the Consumer Electronics Show (CES), TÜV Rheinland Greater China, an international independent third-party testing, inspection, and certification organization (hereinafter referred to as "TÜV Rheinland"), together with TCL and Nanosys, announced the latest outcomes of their collaboration in the display technology field.

Several TCL Products Receive Certification

At CES 2026, TÜV Rheinland and TCL jointly released the White Paper on Perceptual Color Volume. This application guideline for television color evaluation provides an in-depth analysis of the performance differences in three-dimensional color gamut across multiple display technology pathways, including SQD-Mini LED, QD-Mini LED, RGB backlight Mini LED, and OLED. By incorporating human visual perception into technical assessment, the white paper aims to establish a more scientific and perceptually aligned image-quality evaluation framework for the display industry.

During the event, TÜV Rheinland also awarded certificates to several TCL products. The TCL X11L television received TÜV Rheinland Perceptual Color Volume Certification. The TCL Note A1 NXTPAPER e-Note was certified for Paper-Like Display, Flicker-Free performance, and Reflection-Free characteristics. In addition, the T-Pen Pro stylus supplied with the Note A1 obtained TÜV Rheinland Pencil-Like Display certification.

As display technologies continue to advance, traditional two-dimensional color gamut evaluation methods are increasingly unable to meet users' expectations for consistent color performance across diverse usage scenarios. TÜV Rheinland's Perceptual Color Volume Certification addresses these limitations by incorporating the human eye's color adaptation and luminance adaptation characteristics. The evaluation framework extends beyond planar color gamut coverage to three-dimensional color volume coverage, while also integrating key performance parameters such as color accuracy, peak brightness, crosstalk interference, and color consistency across viewing angles. Certified products are required not only to achieve wide color gamut coverage, but also to maintain stable and accurate color reproduction across varying brightness levels and display conditions, placing stringent demands on both display panel technologies and backlight control solutions.

Based on comprehensive testing and evaluation, the TCL X11L television, featuring SQD-Mini LED technology, achieved 100 percent BT.2020 color gamut coverage along with globally consistent wide color performance. The display demonstrates rich and pure color reproduction while effectively addressing common industry challenges such as color crosstalk and color shift, fully meeting the requirements of TÜV Rheinland Perceptual Color Volume Certification.

With the growing prevalence of digital reading and writing, users are placing increasing emphasis on visual comfort when using electronic devices. TÜV Rheinland's Paper-Like Display certification evaluates products across multiple dimensions, including environmental adaptability, contrast stability, resistance to ambient light interference, and eye health protection, helping consumers identify high-quality paper-like display solutions. Testing results show that the NXTPAPER Pure paper-like display technology used in the TCL Note A1 meets the stringent requirements of the Paper-Like Display certification. In parallel, TÜV Rheinland conducted evaluations in accordance with its Flicker-Free and Anti-Reflection certification standards, with results indicating that the Note A1 delivers a stable and comfortable visual experience and effectively reduces visual fatigue during extended use.

As digital note-taking and creative applications become more widespread, consumer expectations for stylus performance-such as writing smoothness, latency, and pressure sensitivity-continue to rise. In response, TÜV Rheinland has established a multi-dimensional evaluation framework under its Pencil-Like Writing certification, assessing key performance aspects including friction and damping sensation, response speed, stroke straightness, pressure sensitivity accuracy, battery life and storage, and overall user experience. The certification requires products to deliver stable, smooth, and realistic physical feedback across various writing scenarios, setting high standards for hardware design, signal transmission, and software algorithms.

Designed with the goal of replicating the experience of writing on paper, the TCL T-Pen Pro stylus works in close synergy with the NXTPAPER Pure display technology of the Note A1. This integration effectively simulates the friction and tactile feedback of paper, providing users with a natural reading and writing experience comparable to that of traditional paper.

TÜV Rheinland and Nanosys jointly released the "Quantum Dot Display White Paper"

Quantum Dot (QD) technology is widely regarded as a key driver enabling the display industry's transition into the era of ultra-wide color gamut and high dynamic range (HDR) following LCD technology. However, rapid market expansion has also led to the misuse of concepts such as "pseudo quantum dots" and "placebo-style quantum dots," which undermines consumer trust and hampers the healthy development of the industry. To address these challenges and promote market standardization, TÜV Rheinland and Nanosys jointly released the White Paper on Quantum Dot Display. The white paper proposes a scientific, phased framework for defining "quantum dot displays," advocating a transition from physical structure verification toward an optical performance-oriented approach. This framework maintains clear technical baselines while allowing room for future innovation, with the aim of guiding the display industry toward greater transparency, authenticity, and performance-driven development.

As a globally leading technical service provider, TÜV Rheinland has been deeply engaged in the display sector for decades. The organization offers a comprehensive portfolio of standards and certification services covering low blue light, flicker-free performance, reflection-free design, paper-like display, circadian-friendly displays, three-dimensional color gamut, dynamic privacy protection, and sustainability-related requirements, all of which are widely recognized by the industry. Looking ahead, TÜV Rheinland will continue to work closely with its partners to advance research in quality evaluation and user experience, contribute to standards development, and support continuous technological progress in the display industry, while providing consumers with reliable guidance for selecting safe and high-quality products.
