Ultra-Slim Unibody Design
A400M features an integrated flat-back design that looks slimmer from the side and more immersive from the front—so it feels less like a device and more like part of your home. Designed for a cleaner wall presence, A400M reduces visual bulk and helps your space look more refined and modern.
Flexible Placement
Whether wall-mounted or placed on a stand, A400M keeps a clean, premium look that fits different rooms and layouts.
Star Ring Cooling System
The star ring cooling system helps reduce heat build-up in tight spaces, supporting stable performance for everyday, all-day viewing.
QD-Mini LED Technology
TCL's QD-Mini LED combines the wide colour performance of QLED with the precise light control of Mini LED, bringing backlight control closer to pixel-level accuracy. It delivers stronger contrast, higher brightness, and richer colour depth—while maintaining stable performance over time.
Up to 448 Precise Dimming Zones
Precise Dimming Series refers to Mini LED TVs with all-domain halo control. A new generation of high-efficiency light-emitting chips, condensed micro-lens optics, and Micro-OD architecture helps shape each zone more accurately and reduce halo. Combined with a high native-contrast HVA panel and advanced light-and-shadow algorithms, it delivers more cinematic contrast and clearer details than conventional TVs.
TCL All-Domain Halo Control Technology
TCL all-domain halo control covers the full path from light generation to final imaging. By integrating high-efficiency chips, self-developed lens technology, Micro-OD, light-and-shadow algorithms, and TCL CSOT HVA panel technology, it helps reduce halo and deliver a cleaner, more premium viewing experience.
Halo Control Components
- Powerful light-emitting chip: High-efficiency chips improve brightness and energy efficiency, reproducing natural bright and dark scenes with greater clarity.
- Condensed Micro Lens: TCL's condensed micro-lens design precisely directs light to improve backlight uniformity and halo control, making details clearer.
- Micro-OD: Helps keep the TV slimmer while supporting cleaner light control, reducing halo and sharpening delicate highlights—like stars against a night sky.
- Dynamic lighting bionic algorithm: Optimizes lighting for SDR and HDR based on human perception and pixel information, improving contrast and detail across scenes.
- Transient response: Faster light response works with the control algorithm to reduce trailing and improve clarity in fast-moving content.
- Bidirectional 23-bit: Senses ambient brightness and colour temperature and fine-tunes the picture to keep colours vivid and consistent.
- HVA panel technology: Enhances contrast by improving light control through the liquid crystal layer, making dark areas darker and the picture more immersive.
High HDR Brightness
Even in a bright room, you can still enjoy clear pictures with vivid colours and see more detail in both sunny and shadowy scenes.
QLED Colour Technology
TCL QLED uses advanced quantum dot materials and a high-transmittance film to improve light efficiency and colour stability. Together with backlight technology, each frame renders rich, vivid colour with smoother gradients—revealing subtle details for a more immersive, lifelike viewing experience. Quantum dot technology renders over a billion colours and delivers up to 93% DCI-P3 coverage for more lifelike visuals.
Bionic Colour Optimization Technology
Intelligently analyzes content to enhance scene colours while protecting natural skin tones for more realistic viewing.
TSR AiPQ Processor
The TSR AiPQ processor integrates TCL's proprietary tuning algorithms and intelligent perception to optimize clarity, contrast, colour, and motion at the pixel level—so every frame looks more natural, layered, and lifelike.
288Hz Game Accelerator
A400M leverages VRR to deliver dual-mode refresh rates: native 4K at 144Hz and 1080p at 288Hz. Run, race, and shoot with less stutter, tearing, and blur for a faster, smoother experience.
