"A display is produced by forming fine pixels on a thin film with a material called photoresist that changes its chemical properties when exposed to light. Until now, photoresist materials have been processed at a high temperature.... high resolution is possible without requiring a high temperature for the process... commercializing an actual product by applying the technology... Thanks to this, it is expected to have the economic ripple effect of more than KRW 60 billion (USD $50 million) in 2021 alone"
