QD-Mini LED with Precise Dimming Technology
TCL's QD-Mini LED combines the merits of QLED and OLED technologies, transforming the traditional backlight into lighting that is close to pixel-level precision. It utilizes the world's leading QLED technology, offering contrast and colour gamut comparable to OLED, while also providing higher peak brightness and a longer lifespan. This represents the future technology of large-screen displays.
448 Precise Dimming Zones
The Precise Dimming Series features Mini LED technology with all-domain halo control. The new generation of powerful light-emitting chip, condensed micro lens and Micro-OD make the light shape of individual zones more perfect, with halo control ability several times that of ordinary zones. Combined with CSOT HVA panel technology with higher native contrast ratio and the world's leading light and shadow control algorithm, the 448 Precise Dimming Zones deliver deeper blacks and higher brightness, dramatically improving the TV's comprehensive picture quality performance compared to ordinary TVs.
TCL All-Domain Halo Control Technology
TCL all-domain halo control technology covers the entire path from light generation to imaging, integrating high-efficiency light-emitting chips and self-developed lens technology, combined with Micro-OD, light and shadow control algorithms, and TCL's unique self-produced high-end CSOT HVA Panel technology. Through system-level precise control of light, it effectively solves the halo problem and delivers a premium viewing experience.
Powerful Light-Emitting Chip
The A400U's ground-breaking Powerful Light-emitting Chip significantly improves brightness and energy efficiency compared with the previous generation of conventional light-emitting chip, reproducing natural bright and dark scenes with clarity.
Condensed Micro Lens
TCL's self-developed condensed micro lens technology precisely controls light direction through its arch bridge dimming design. Its selection of nano-optical materials with greater plasticity form a golden curvature with super light-focusing properties, and precisely controls light point by point, greatly improving the backlight uniformity and halo control capabilities, making picture details clearer.
Micro-OD
With TCL's powerful Mini LED optical technology, the A400U delivers an astonishing Micro-OD that not only offers a slimmer TV unit but also significantly reduces the Mini LED halo issue by working with the condensed micro lens and ultra-high zoning, giving the stars in the night sky a deep, delicate, and sharp look.
Dynamic Lighting Bionic Algorithm
Combined with human perception characteristics and picture pixel information, the lighting details are optimized for SDR and HDR signals, while the details and contrast of light and dark scenes are greatly improved. This delivers more real lighting effects of streaming media resources on TCL TV.
Transient Response
Transient response prevents dark shadows, bright spots, and trailing caused by backlight lag in motion pictures, making motion pictures sharper and enhancing your viewing experience.
Bidirectional 23 Bit Precision Control
Bidirectional 23 bit precision control technology accurately senses the ambient brightness and colour temperature, and finely controls the TV brightness and colour temperature to make the picture more vivid and colourful.
CSOT HVA Panel Technology
CSOT's HVA Panel technology stands at the forefront of the industry. By incorporating polyimide into the liquid crystal molecules, it forms a butterfly-wing-shaped microstructure. Combined with more precise panel design, this innovation enables precise control over the light passing through the liquid crystal layer, making dark areas appear even darker and significantly enhancing the screen's contrast ratio of up to 7000:1, delivering a more vivid and immersive visual experience.
HDR 2500 Nits Peak Brightness
Thanks to its peak brightness of 2500 nits, the A400U features an ultra-high contrast ratio of 25 million:1 and a higher dynamic range. With its precise dimming capability, the A400U displays both deep darkness and bright, vivid details.
QLED Colour Technology
TCL QLED utilizes Colourful Quantum Crystals, which integrate nanoscale quantum dot materials with organic materials in multiple layers. The high light transmittance film equipped achieves a 10% energy saving for the entire machine by enhancing the light transmittance. Together with backlighting technology, this breakthrough achieves exceptional colour and optical performance. Each frame masterfully renders more than a billion hues of perfect vivid colours, showcasing stunningly vivid colours with enhanced brightness that illuminates subtle details.
High-Transmittance Filter
The screen of the A400U is equipped with a new-generation high light transmittance film, which greatly enhances the display purity of vivid colours while maintaining high light transmittance. This significantly enhances colour stability and improves light transmittance, resulting in more stunning colour performance.
Colourful Quantum Crystal
TCL QLED introduces the next-generation Colourful Quantum Crystal, featuring a more stable multi-layer nano-protection and precision crafting. This innovation delivers an extraordinary, long-lasting colour experience with exceptional brilliance and depth.
93% DCI-P3 Ultra-High Colour Gamut
Utilizing Quantum Dot technology, the A400U unveils over 1,000,000,000 hues of vibrant and precise colours, providing up to 93% colour gamut according to DCI-P3 standard, bringing digital environments to life in ways previously unimaginable.
Bionic Colour Optimization Technology
Optimizing colour based on human preferences, TCL intelligently analyzes image content and enhances scene colours with remarkable precision, boosting realism and immersion. At the same time, it restores and protects natural skin tones, delivering vibrant, true-to-life visuals.
Pioneer in Quantum Dot Technology
TCL remains at the forefront of innovation, investing heavily in QLED technology with a total of 2913 patents. With a dedicated team of nearly 100 experts and an international Quantum Dot Lab, TCL continues to push the boundaries of display technology.
39.9mm Ultra-Slim Flat-Thin Design
TCL A400U's 39.9mm integrated flat and slim design, plus nearly seamless 3mm-gap wall mounting, fuses art and technology to blend effortlessly into any home.
Star Ring Cooling System
The Star Ring Cooling System adopts aviation-grade heat-conducting materials and is paired with a bionic fin radiator structure, which greatly improves heat dissipation efficiency. It also optimizes the design of heat dissipation air ducts to reduce heat accumulation. Among products in the same class, the spatial temperature rise is reduced by 3 to 5 degrees.
Light Home Aesthetics
TCL aims to advocate the future concept of Light Living and Chic Life Style, conveying to users a comfortable and natural life intention, and moving towards a warmer and more considerate direction. The versatile home decoration design allows you to match your home decor and adapt to your preferences, filling the home with a warm, flowing sentiment.
HVA Pro Panel
The liquid crystal display features nanoscale bionic technology, which forms a butterfly-wing microstructure by adding polyimide to the liquid crystal molecules. This allows for precise control over the amount of light passing through the liquid crystal layer and a notable improvement in contrast with 5x contrast enhancement, making the image richer in details. It also comes with a nanoscale low-reflective film that reduces reflection on the display and presents a more crystal-like screen with sharper details.
