Product Description

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. 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.

TCL AI:
TCL AI has developed a robust underlying hardware capability through independent research and development. It has created a quantum supercomputing platform that integrates a variety of self-developed professional models and has built an industry-leading Mariana database. This enables continuous deep learning and evolution of the TCL AI model. In addition, TCL AI deeply integrates many AI capabilities and has a large number of powerful scenario-based intelligent agents. It provides you with a smarter and more convenient audio-visual entertainment experience across four dimensions: AI image quality, AI sound quality, AI interaction, and AI content generation.

Art Gallery Mode:
Transform your living space with the TCL A400 Pro's Art Gallery Mode a curated digital canvas that turns your television into a work of art. Browse over 80 masterpieces from global museums, spanning Impressionism, Abstract Geometry and Contemporary Art, all displayed in stunning 4K resolution on a matte, anti-glare HVA panel that mirrors the texture of a real canvas. Generate bespoke AI artwork in seconds, or upload your own photos to create a custom gallery.
