The World-leading QD-Mini LED

QLED with Mini LED

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

Deeper blacks, brighter highlights

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

Mini LED TV: The Halo Eliminator

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.

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

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

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

Bright and brilliant

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

More than a billion hues of vivid colour

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.

Up to 93% DCI-P3

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

Powered by TSR AiPQ Processor Computational image quality

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.
