South Korean university solves a major manufacturing problem
Much as serious home entertainment fans might love OLED TVs, most will surely wish they didn’t have to pay so much to buy one. While prices have slowly come down over recent years, to a point, in fact, where many OLED TVs can be considered good value for the quality they offer, the fact remains that even the cheapest OLED TV models still carry premium price tags compared with the majority of the LCD TV world.
This barrier to OLED entry might soon be overcome, though, thanks to a new breakthrough in OLED manufacturing developed by researchers at South Korea’s Pusan National University.
The new solvent-resistant hole injection layer material for the scientists among you!) developed by Professor Hwang and his colleagues also provides supposedly excellent film-forming properties, optimum energy and high mobility - adding up to a development that the university believes represents “a major stepping stone toward commercial viability of solution-processed OLEDs.”
The solution-processed OLED approach can, the Pusan National University researchers claim, run at large scale fabrication levels much more easily and affordably than the current notoriously cost and labor intensive approach to making OLED displays.
The Pusan National University research team first presented technical details of its OLED breakthrough in a paper published online on October 22 2022, before getting the paper published in the Chemical Engineering Journal on 15 February 2023.
