Researchers develop selective transfer printing technology for microLEDs

(Nanowerk News) MicroLEDs are a light source for next-generation displays that utilize inorganic LED chips with a size of less than 100 µm. MicroLEDs have attracted a great deal of attention due to their superior electrical/optical properties, reliability, and stability compared to conventional displays such as LCD, OLED, and QD. To commercialize microLEDs, transfer printing technology is essential for rearranging microLED dies from a growth substrate onto the final substrate with a desired layout and precise alignment. However, previous transfer methods still have…
