Startup Sitan Semiconductor International Co. Ltd. (Hong Kong, China) has developed a series of monochrome and full-colour microLED display modules.
Sitan adopts monolithic integration technology that can provide monochrome modules and single-screen full-color microdisplay modules based on quantum dot color conversion. These displays vary in resolution from 400 by 300 pixels up to 1920 by 1080 pixels and with module sizes of between 0.13-inch diagonal up to 0.45-inch diagonal.
Applications include AR/XR glasses/headsets, head-up displays, projection displays. The 0.13-inch 1024 by 768 microLED display module has pixel density of 10,000ppi.
The company was founded in 2021 by Zhaojun Liu, a researcher at Hong Kong University of Science and Technology. Liu worked in the Advanced Displays and Optoelectronics Laboratory on active matrix driven microLED displays.
Sitan has been able to demonstrate displays brightness exceeding one million nits and of thousands of nits when used in conjunction with a diffraction optical waveguide. This allows in-glasses AR/XR displays capable of working outdoors, the company said.
The company has demonstrated an AR glasses product with full-color display of 0.18-inch with power consumption below 100mW and a screen brightness of more than 10,000 nits.
