Bicolour, large area, inkjet-printed metal halide perovskite light emitting diodes

Abstract

We demonstrate a bicoloured metal halide perovskite (MHP) light emitting diode (LED) fabricated in two sequential inkjet printing steps. By adjusting the printing parameters, we selectively and deliberately redissolve and...

Improving the uniformity of the inkjet-printed polymer film in a bank by Marangoni flow and contact line sliding

“…Inkjet printing technology is a direct patterned solution processing method, which has been widely used to process patterned organic light-emitting diodes (OLED) in recent years. [1][2][3][4][5][6][7] It has the advantages of no contact with the substrate, material saving, pixelated processing and high efficiency in industrial production. [8][9][10] To achieve pixelated processing, the substrate of OLED devices usually needs to be patterned.…”
