In his update from Display Week 2024, Chris Chinnock of Insight Media featured ViStar, a new subsidiary of Visionox dedicated to advancing MicroLED technology.

1. Flagship 88-inch MicroLED Display

• Modular Design: The 88-inch 4K display is built from several 14.5-inch modules, which are themselves composed of a 2×8 matrix of smaller tiles.
• Zero-Bezel Splicing: To create a seamless “splicing” effect, the edges are metalized with contacts, allowing modules to be tiled together without visible seams.
• Technical Specs: It features a 0.5 mm pixel pitch and 25-micron full-color MicroLEDs on an LTPS-on-glass active-matrix backplane.
• Performance: The display achieves a peak brightness of 2,000 nits, 10-bit color depth, and a 100% DCI-P3 color gamut.

2. Manufacturing & Production Process

• Mass Transfer: ViStar uses a stamp-based mass transfer process and reported a record-setting 99.995% yield rate.
• Quality Control: The company utilizes a proprietary algorithm for binning and characterizing LED wafers to ensure maximum color and brightness uniformity across the screen.
• Production Roadmap: Equipment for the world’s first TFT-based Micro-LED production line was installed in late 2024, with a goal of scaling toward mass production by late 2025.

3. Business Model

ViStar’s strategy is to act as a module supplier. They intend to sell their 14.5-inch MicroLED modules to third-party manufacturers, who can then integrate them into various end-user products, such as:

Command and control center displays.

High-end home theater TVs.

Large-scale digital signage.
