Noesi Technology unveils the world's first XGA vertical-stacked full-color Micro-LED micro-display chip.

Recently, Innovision Technology successfully lit up the world's first XGA vertical-stacked full-color Micro-LED micro-display chip. This chip integrates RGB tri-colors and a CMOS driving backplane using the WLVSP™ (Wafer-Level Vertical Stacked Pixels, hereinafter referred to as VSP) technology solution, marking a significant breakthrough in Innovision Technology's core technology for Micro-LED full-color micro-display single chips.

Innovision Technology is a startup dedicated to commercializing Micro-LED micro-display technology and providing the best solutions in the micro-display field for its customers. Its VSP (Vertical Stacked Pixel) technology platform breaks through the limitations of pixel miniaturization in the micro-display field, enabling the creation of high-performance micro-display chips.

 Single-chip full-color is the ultimate challenge for Micro-LED micro-displays. Current commercial color solutions are achieved through the assembly of red, green, and blue chips combined with prism structures. However, this combined light approach has limitations in size, efficiency, and cost. Innovision Technology's successful lighting up of a single-chip full-color micro-display chip is expected to significantly accelerate the commercialization process of color Micro-LED micro-displays globally.

The lighting of this chip utilizes Innovision Technology's independently developed innovative VSP technology. This technology integrates the integrated circuit process with LEDs through vertical stacking of multiple light-emitting units. It combines the advantages of large-size epitaxy, homogeneous integration, and extremely small pixel sizes to achieve breakthroughs in cost, yield, and performance. This approach is poised to become the optimal technological solution for the commercialization of Micro-LED micro-display chips.

Advanced technology and leading manufacturing processes accelerate Innovision Technology's commercialization progress. In September 2023, Innovision Technology successfully established the VSP process flow, achieving vertical integration of the AlGaInP and GaN material systems. In March 2024, Innovision Technology successfully lit up a single-chip full-color vertical-stacked micro-display chip with active driving, marking another significant breakthrough following its previous achievement of lighting up the world's smallest 0.12-inch monochrome micro-display chip. In the next phase, Innovision Technology will continue to focus on advancing the performance optimization of single-chip full-color Micro-LED micro-display chips to achieve large-scale production at the fastest possible pace.
