0.18cc Full-color Micro-LED Light Engine Powered by QDPR Technology

The miniaturization of LEDs has enabled their application in displays of various sizes, with Micro-LEDs emerging as a transformative technology in the field of micro-displays. Known for their high brightness, low power consumption, and exceptional reliability, Micro-LEDs are widely regarded as the optimal solution for AR/XR terminal devices. Early development of Micro-LED micro-displays built upon traditional LED manufacturing processes, utilizing sapphire and flip-chip solutions for low-resolution displays. However, these approaches faced significant limitations in meeting the stringent requirements of AR/XR applications, particularly due to challenges in GaN material growth and integration processes, which hindered the realization of single-chip full-color displays. Recent advancements in single-chip integration technology have paved the way for wafer-level full-color Micro-LED micro-display chips, positioning this technology as a leading candidate for future AR/XR systems.

A notable breakthrough in this field is the development of a 0.13-inch micro-display with a full-color resolution of 320×240 (Micro-LED resolution of 640×480) and color performance exceeding 100% of the DCI-P3 standard. This technology achieves a peak full-color brightness of 500,000 nits while maintaining low power consumption, with a single-chip full-color light engine volume of just 0.18cc, the smallest in its class. The architecture also demonstrates significant potential for further performance enhancements. Beyond display capabilities, this innovation represents a critical step toward mass production, leveraging quantum dot lithography as a highly feasible approach for full-color Micro-LED micro-display fabrication. The integration of versatile interfaces, such as MIPI and QSPI, ensures broad compatibility with diverse hardware systems, reducing development costs and accelerating adoption in AR/XR applications. These advancements underscore the potential of Micro-LED technology to redefine micro-displays for next-generation AR/XR devices.
