China-based MicroLED microdisplay developer Jade Bird Display announced a new 0.13" VGA microdisplay, which it says is the world's smallest microdisplay. This is a monochrome (red) display.
JBD did not yet share any details on this new display, but it says it will be launched by the end of 2020.
In July 2017 the company demonstrated a 5000 PPI active-matrix group III-V microLED array on Si ICs. In 2019 JBD unveiled more prototypes, including a 2 million nits display and a 10,000 PPI display.
