Currently, Skyworth and Sony are the leading brands in high-density backlight zoning technology, achieving industry-leading display effects through different technological paths.
Skyworth: Chameleon Display Technology Platform
Skyworth's Chameleon Display Technology Platform is the core of its high-density backlight technology. Through end-to-end innovation encompassing hardware, algorithms, and sensing, this platform achieves an extremely high number of backlight zones within an ultra-thin body.
Technical Highlights: Utilizing ultra-macro OD10 technology, the light mixing distance is shortened to an industry-leading 10mm, allowing thousands of high-density backlight zones to be accommodated within a limited space. For example, its 85-inch wallpaper TV features up to 3840 QD-Mini LED backlight zones.
Picture Quality Performance: Combined with its self-developed Chameleon AI picture quality chip S7 (2.5T integrated AI computing power), pixel-level light control is achieved, significantly improving backlight uniformity (+30%) and halo suppression (+40%), and supporting adaptive ambient light adjustment. Sony: RGB High-Density LED Backlight System
Sony showcased its RGB high-density LED backlight system at AWE 2025, focusing on high color purity and a wide color gamut, especially suitable for large-screen viewing needs.
Technical Features: Employs an RGB three-color emission method, offering excellent native color performance and a greater advantage on large-screen displays. Sony developed a dedicated control chip for precise light control.
Market Positioning: Aiming to bring a cinematic experience to the home, enhancing immersion through high-density backlight technology and collaborating with content platforms to optimize calibration modes.
Other Brand Technology Updates
TCL CSOT: In the Mini LED backlight field, its AM Mini LED technology based on LTPS substrates can achieve ultra-high zone design with good halo control, but the reference information does not explicitly mention the specific number of zones.
Industry Trends: High-density backlight technology is developing towards higher zones and more precise light control. Skyworth and Sony's technologies represent the current advanced level in the industry.
