Mini Optoelectronics has made significant progress in high-resolution Micro LED full color display, developing a highly consistent pixel based quantum dot color conversion color film preparation technology. This technology solution can reduce the number of massive transfers by two-thirds, effectively solving the technical pain points of low yield, low light efficiency, and high difficulty in massive transfer of Micro LED red light chips, further improving yield, reducing repair, and reducing costs, injecting new momentum into the industrialization process of Micro LED.

Breaking Through Blockages and Further Industrialization of Micro LED

In recent years, Micro LED display technology has developed rapidly due to its significant advantages, but due to factors such as immaturity and cost barriers, there are numerous obstacles to the large-scale commercialization of Micro LED displays. Quantum dot color conversion technology is a common key technology for Mini/Micro LED, OLED, and LCD wide color gamut displays. The color conversion scheme is significantly superior to the RGB display scheme in terms of transfer difficulty and circuit design, achieving lower power consumption and higher yield. It is also the best way to achieve high-resolution Micro LED full color display, and is most likely to be the first to achieve Micro LED industrialization.

On the basis of this technical solution, the Quantum Dot Color Converter (QDCC) developed by Mini Optoelectronics can accurately and efficiently convert high-energy blue light into red and green light, comprehensively improving display performance such as color gamut coverage, color control accuracy, and red green color purity. Based on this, the company has developed high consistency quantum dot color conversion films with different pixel arrangements, further breaking through the technical challenges of Micro LEDs.
