Chinese electronics company TCL announced on May 18 that it will launch its ultra-slim television model, the “A400M,” in the South Korean market.
The A400M is a TV based on Quantum Dot (QD)-Mini LED technology and features an ultra-slim integrated design with a thickness of just 39.9 millimeters. Its flat one-piece rear body design delivers a sleek appearance while enhancing screen immersion.
The TV can be installed neatly either as a wall-mounted unit or with a stand, allowing it to blend naturally into home interiors. It is also equipped with a “Star Ring” cooling system that minimizes heat buildup even in confined spaces, ensuring stable long-term performance.
Using QD-Mini LED technology, the A400M delivers near pixel-level backlight control. The TV combines up to 448 precision local dimming zones (based on the 98-inch model) with TCL's all-domain halo control technology to reproduce deep blacks and bright highlights simultaneously.
The model also incorporates ergonomic light optimization and rapid response technologies to maintain vivid image quality even in bright environments, offering a more immersive viewing experience. Its high-performance processor automatically optimizes sharpness, contrast, color, and motion at the pixel level.
The display supports refresh rates of up to 288Hz, enabling smooth and responsive gaming performance without screen tearing or lag. The TV also offers immersive sound and a wide range of content powered by Google TV.
A TCL official said the A400M is designed to satisfy consumers looking for a clean and sophisticated living space while also delivering strong picture quality, gaming performance, and sound. The company added that the model is expected to appeal to consumers with diverse lifestyle preferences.
