A team from Kaist in Korea has developed microLEDs and a transfer mechanism for the chips that can transfer a 50 x 50 array of LEDs. The LEDs are then interconnected using anisotropic conductive film (ACF). The LEDs are 5µ thick and less than 80µ wide.
The group claims that the use of flexible vertical microLEDs (f-vled) allows an optical power density of 30 mW/mm² which is said to be three times that of lateral microLEDs.
There is a video on YouTube that explains the process.

Although there are applications in displays, the group seems to be focusing initially on medical applications for these LEDs. (BR)
