It is understood that the materials science and engineering team of Yonsei University in South Korea has developed a3D printingTechnology, can print the OLED screen into any shape of transparent structure, which means that almost anything can be turned into a transparent color display. The team’s research paper was published in the journal “advanced science”, aiming to elevate the development and manufacturing of complex screen shapes to a new level by printing 3D support structures and 3D screen electronic devices. Current technology usually requires 3D structures to be used in conjunction with linked 2D screens, and this technology allows designers to create screens of almost any shape without any additional thermal annealing steps.
This method uses a digital light processing (dlp) system to print a transparent plastic “frame” with a gap where the screen is to be placed, and then moves to a five-axis electric hydraulic jet (e-jet) printer, which can Create an oled screen using the following layers:
1. Transparent electrode at the bottom, including silver nanowire matrix
2. Pixel limiting layer made of light-cured polyurethane
3. Poly(ethylenedioxythiophene): the hole transport layer of polystyrene sulfonate
4. Use (try to speak quickly) 4,4′-double[4-（二-对甲苯基氨基）苯乙烯基]Biphenyl-doped 2-tert-butyl 9,10-bis(naphtha-2-yl) light-emitting layer anthracene
