Overview
Koyj makes coated optical films, thin sheets applied inside the backlight units of LCD screens to spread light evenly and reduce glare, and supplies them to LCD display manufacturers.
It also operates subsidiaries that produce metal-cast automotive parts and electronic organic and inorganic materials, including inputs for secondary-battery cathodes and semiconductor and display applications. Listed on KOSDAQ, Korea's tech and small-cap board, Koyj's core business is optical film coating, where it mixes its own coating solutions in-house rather than purchasing ready-made formulas, a process it says lowers production costs.
