TCL 85 inch 4K QD-Mini LED Google Smart TV 85C6K Installation Charges Extra Applicable QD-Mini LEDQLED with Mini LED 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 also utilizes the world's leading QLED technology, offering contrast and color gamut comparable to OLED, while also providing higher peak brightness and a longer lifespan. This represents the future technology of large-screen displays. TCL All-domain Halo Control TechnologyMini LED TV: The Halo Eliminator The 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 high-end 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 ChipMaster light and dark, capture intricate details Compared with the previous generation of conventional light-emitting chip, C6K's ground-breaking Powerful Light-emitting Chip significantly improves brightness and energy efficiency, reproducing natural bright and dark scenes with clarity. Condensed Micro LensMicro lens, big power TCL's self-developed condensed micro lens technology precisely controls light direction through its arch bridge dimming design. Through the elite light type calculation model, a golden curvature with super light focusing ability is formed, which greatly improves the backlight uniformity and halo control for clearer screen details. Micro-ODBetter image quality, thinner body With TCL's powerful Mini LED optical technology, C6K delivers an astonishing Micro-OD. It not only offers a slimmer TV unit but also puts an end to 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.
