Mojo Vision, a high-performance micro-LED company, has announced that it successfully powered the world’s highest-density red microLED microdisplay.
The company states the powering of the red micro-LED display is an important step in overcoming challenges of delivering high-performance and reliable full-color microLED displays. To accomplish its goals, the company points out that it used its proprietary Quantum Dot (QD) process to display visually vibrant, state-of-the-art red micro-LEDs, measuring 1.37um in diameter and set on a 1.87um pitch. The level of quality at this size is critical in meeting the full-color requirements for augmented reality (AR) and extended reality (XR) markets.
“The ability to make very small red, green, and blue micro-LEDs on the same substrate is critical to achieving vibrant and effective full color microdisplays,” says Dr. Nikhil Balram, CEO of Mojo Vision.
“Powering a true red display, rather than leaning toward orange as others do, at this size and specification puts us a big step closer to producing a micro-LED display that will meet or exceed the current performance and form factor requirements for AR and XR products.”
According to the company, one of the primary challenges with current display technologies, such as OLED, in today’s AR/VR headsets is the ability to deliver optimal brightness and contrast dynamically as environmental light conditions change. When microLEDs are commercially available, the displays will be able to provide rich device functionality in all ambient conditions for AR and XR emerging products. Mojo Vision’s high-density red microLED is the industry’s first to overcome wavelength and visual challenges with ultra-high pixel density, brightness, contrast, color gamut and energy efficiency.
Mojo Vision asserts that while it is typically easier to deliver high-quality micro-LEDs at larger sizes (> 5um), the industry has struggled with smaller microLEDs, particularly those using color conversion materials. Mojo Vision’s breakthrough sets a new state-of-the-art benchmark for microLED manufacturers by achieving true red vibrancy at a record-small pitch exceeding past records for red wavelengths of 620 nanometers or more that are required by major color standards used in broadcast and consumer displays.
“Full color micro-LED microdisplays are going to start emerging in the market in the coming years,” adds Dr. Guillaume Chansin, director of display research at Display Supply Chain Consultants (DSCC).
“Mojo Vision’s prototype stands out as a new milestone, by demonstrating red color conversion with a sub-2um pixel pitch. This development is significant for the micro-LED industry and shows the potential of Mojo Vision’s approach towards full color, high resolution microdisplays.”
