Breakthrough for single panel RGB microLED display
Mojo Vision in the US has integrated red, green and blue (RGB) sub-pixels into a first-of-its-kind single panel.
The single panel microLED display, shown at CES 2024 in the US this week, uses proprietary high performance Quantum Dots (QDs) and integration processes developed by Mojo Vision for use in augmented reality (AR) devices outdoors.
The proof of concept integrates 1.3um diameter red and green QD-based sub-pixels adjacent to 1.3um diameter native blue sub-pixels, demonstrating the viability of the company’s path to developing single-panel RGB micro-LED displays.
The company’s focus on blue micro-LEDs at 200- and 300-mm wafer scale, coupled with its proprietary high-performance QD technology, leads the display industry to more scalable and commercial solutions. Current commercially available QDs, designed for conventional displays like LCD, lack the reliability under high light conditions required for AR glasses says MoJo.
“Mojo Vision’s proprietary process for robust quantum dots addresses the common industry challenge of achieving high brightness and durability when creating single-panel RGB displays,” said Nikhil Balram, chief executive officer of Mojo Vision.
“This process ensures the technology’s reliability, coupling high image quality with efficiency and lifespan. As companies develop wearables and smart glasses equipped with artificial intelligence (AI), micro-LEDs enable much better display resolution, brightness, contrast, and dynamic range, crucial for rendering detailed images and supporting the advanced image recognition that the disruptive industry requires.”
The company previously announced a 300mm GaN-on-Silicon micro-LED array wafer, marking important progress towards maturing micro-LED manufacturing. It also demonstrated a vibrant red micro-LED microdisplay using 1.3um diameter red QD regions on top of 1.3 um diameter blue micro-LEDs.

“Augmented reality technology continues to progress toward the goal of seamlessly blending immersive, virtual experiences into the physical world and enabling natural interactions with digital objects,” said Dr. Achin Bhowmik, president of the Society for Information Display (SID). “Achieving this requires the high dynamic range, great contrast and image quality, super resolution, low power consumption and compact form factor of micro-LED. Mojo Vision’s single-panel RGB display is a significant advancement towards realizing this promise.”
