On December 16, the 2024 TCL QD-Mini LED new technology launch conference with the theme of "Light Creates Everything" was officially held. A series of leading technologies such as All-in-One Partitioning, Quantum Dot Pro 2025, and Colorful XDR made their debut. Through the upgrading of Mini LED underlying technology, it brought unprecedented picture quality experience.

TCL has recreated the ceiling of Mini LED technology, creating a top-level visual feast for users. It also indicates that the TV industry will enter the next cycle and start a new chapter of development with underlying technology as the core.

Start the image quality leap and reshape the world

Backlight partitioning and peak brightness are the two core indicators of Mini LED TVs, which have greatly improved the picture quality of TVs. However, in recent years, many consumers have found that some TV products have high indicator parameters, but the picture quality is not satisfactory. In fact, improving the picture quality of Mini LED TVs requires a complete set of full-link systematic optical solutions, involving a large number of Mini LED underlying technologies. Only TV products that truly apply these underlying technologies can give full play to the role of backlight partitioning and peak brightness in improving picture quality and create an ultimate picture quality experience for users.

As the earliest TV company in the industry to enter the Mini LED market, TCL has upgraded the underlying technology of Mini LED based on years of deep cultivation and accumulation, achieving a technical breakthrough in the complete link system level from backlight to imaging, including light-emitting chips, lens technology, OD design, light control algorithms and screens. Based on this, TCL has developed the most powerful light control system for Mini LED at present - Vientiane Halo Control Technology. The partition using this technology is Vientiane partition, and the light control effect is several times that of ordinary partitions, bringing consumers an unprecedented Mini LED picture quality experience.

The upgrade of the light-emitting chip is the first step in creating the Wanxiang partition. TCL upgraded the sapphire high-gloss crystal base to a super-energy high-gloss crystal base, and used the ALD atomic-level corrosion-resistant process to achieve a significant improvement in the brightness and energy efficiency of the TV. Compared with the previous generation of multi-core Mini LED chips, the brightness is increased by 53.8% and the energy efficiency is increased by 10%. Second, TCL uses an upgraded version of the arch bridge light control technology and adopts more reliable LSR flexible optical materials. At the same time, through the exclusive elite light type calculation model, the new generation of focusing micro-lenses can bring 86% improvement in backlight uniformity and 67% improvement in halo control ability under the same number of partitions, better shaping light type, removing halo, and achieving precise light control.

In the third link of the Mini LED imaging chain, TCL adopts a macro OD backlight design. The distance between the backlight panel and the diffuser is extremely small, so that the partitions do not affect each other, effectively controlling the halo and improving the brightness uniformity of the TV. Not only is the picture more delicate, but the outlines of objects are also clearer.

To accurately control the backlight status, intelligently optimize the image signal, and achieve precise coordination between the partition and the picture signal, a powerful light and shadow control algorithm is needed. As early as the beginning of this year, TCL launched two algorithms, transient response and bidirectional 16-bit, to strengthen the control of Mini LED backlight. This time, not only has it been upgraded to 23-bit based on the bidirectional 16-bit, but also a new ultra-dynamic light and shadow bionic algorithm has been added. It combines the human eye perception characteristics and the picture pixel information to intelligently optimize the SDR signal and optimize the SDR signal to a nearly HDR effect. The HDR effect can be greatly enhanced, the details and contrast of bright and dark scenes can be greatly improved, and online film and television resources can also present more realistic light and shadow details.

As the only company among many domestic TV manufacturers that owns a screen factory, TCL has always insisted on independent research and development of screens. The Huaxing HVA screen it launched has liquid crystal molecules arranged in a butterfly-wing shape, which has stronger light-shielding ability and a faster response speed. It can accurately control the direction of light, has a higher contrast, and is more suitable for Mini LED products, making it the best partner for Mini LED TVs.

In summary, through full-link optimization from backlight to imaging display, the newly launched Vientiane halo control technology brings industry-leading Vientiane partitioning, achieving the strongest light control effect, making the light and dark contrast of the TV screen more realistic and the details more delicate, reshaping the Vientiane world on the screen and opening up a real leap in picture quality.

Both color and brightness are upgraded to make it brighter, longer-lasting and more colorful

Compared with traditional LED TVs, Mini LED TVs have a higher number of backlight zones, which allows for more precise control of the brightness of each zone, improving the contrast and layering of the picture. TCL has once again achieved a qualitative leap in color performance and peak brightness with its innovative and upgraded Quantum Dot Pro 2025 and Colorful XDR technologies, presenting users with more vivid and realistic picture effects.

In terms of materials, Quantum Dot Pro 2025 has been fully upgraded. It has been upgraded from quaternary quantum crystal to colorful quantum crystal, using a composite nano-diamond structure, and using multi-layer co-extrusion technology and high-precision mixing technology to make the quantum dot layer, which greatly improves the luminous efficiency. At the same time, TCL uses human color optimization technology, through intelligent recognition of the color of the picture, dynamic color management according to the different colors of the picture, and multi-dimensional rendering, so that the color display of quantum dots is more in line with the human eye's perception of the world.

With the combined effect of the new quantum dot material and color adjustment, TCL TVs equipped with Quantum Dot Pro 2025 have the industry's highest color gamut value, can display 1.07 billion colors, and the TV's full-screen color purity is increased by 95%, the color accuracy ΔE < 0.99, and the color performance is accurate. More importantly, due to the inorganic material characteristics of quantum dots, its stable service life reaches 100,000 hours without fading, truly realizing a 1 billion primary color screen and 10 years of good color.

At the same time, TCL launched the Colorful XDR technology, whose ultra-dynamic light control allows the TV to achieve long-term high-brightness display, solving the problem that the peak brightness of Mini LED TVs can only be maintained for a short time before rapidly decaying. When users watch the high-brightness scenes of movies and TV series, they can see the real and restored high-brightness scenes, and the viewing experience will not be affected by the fact that the brightness is only bright for a moment and then dims.

Through the technological upgrades of Quantum Dot Pro 2025 and Colorful XDR, TCL brings a new generation of advanced QD-Mini LED products with better color experience. They are brighter, brighter and more eye-friendly, achieving a truly valuable improvement in picture quality experience for users.

As easy to use as a mobile phone, large model enables full-dimensional

In addition to the comprehensive breakthrough in Mini LED core technology, TCL has also achieved innovative breakthroughs in the control experience. Based on the easy-to-use functions of the smart control desktop, the smart control system 3.0 deeply customizes the functions for audio and video, games, entertainment and other smart scenes, upgrading the desktop to a TV system that is as easy to use as a mobile phone, making it even easier to use.

First, the desktop supports editing more card components. Users can add and delete more than 300 smart cards, and can also put smart assistants, weather and other tool components in a prominent place on the desktop. Secondly, the TV control path is more simplified. In addition to the shortcut keys of the remote control, you can also use voice to add/delete/move cards, and aggregate all screen projection functions for display, so that even the elderly and children can get started; in addition, it supports the four major NAS protocols FTP/SMB/NFS/WebDAV, and can also aggregate local and network disk resources, so that audio and video geeks can quickly find the movies they want to watch; finally, exclusive collection skins are customized for the three major game consoles Xbox/Switch/PlayStation, which automatically identify the host adaptation, and maximize the sense of ritual and immersion. In addition, it is equipped with a hardcore high-playing second control console for game enthusiasts, which integrates many graphic effects and can be used for exclusive game settings to fully meet the diverse usage habits and needs of different users.

It is worth noting that as a technology manufacturing company, TCL has made forward-looking arrangements and continued to invest in research in the field of AI, covering the optimization of sound and picture quality and the improvement of TV user experience. Now it has launched the Fuxi AI big model equipped with TCL's self-developed quantum supercomputing platform, so that users' ideas can be understood by the TV, and what they think is what they get, providing users with the content and services they need in a timely and accurate manner.
