Latest Patents

Wonhoe Koo holds a patent for a "Buckled organic light emitting diode for light extraction without blurring." This invention features a layered OLED device that incorporates a buckled structure over a portion of the light emitting face. The design aims to improve light output compared to traditional flat OLED devices. The buckled structure consists of both fine and gross buckling, which are quasi-periodic. The method of producing this OLED device involves a transparent substrate coated with a transparent elastomeric layer, onto which a thin metal layer is deposited at an elevated temperature. Upon cooling, the metal layer buckles, forming the quasi-periodic buckling. The metal layer is then oxidized to create a metal oxide layer that retains this buckling. An OLED with a buckling structure is constructed on this metal oxide layer, preserving the buckling effect.
