Latest Patents
One of his latest patents is a display device that includes a display panel, a supporter disposed on the surface of the display panel, and an adhesive layer between the supporter and the display panel. The supporter consists of metal layers spaced apart from each other, with a cushion layer surrounding the metal layers. The adhesive layer has a first area overlapping the metal layers in a vertical direction to the display panel and a second area that does not overlap the metal layers. Notably, the modulus of the second area of the adhesive layer is larger than that of the first area.
Another significant patent is a method for removing nitrogen and phosphorous in wastewater. This method employs fermentation broth obtained from anaerobic fermentation of organic solid wastes. The process involves subjecting organic waste material to anaerobic fermentation at temperatures between 30 to 40°C for 2 to 4 days. The fermentation broth is then added to a sequencing batch reactor with alternating anaerobic-aerobic-anoxic cycles. This innovative method can remove more than 95% of nitrogen in the influent wastewater and maintain phosphorous concentration below 1 ppm, all while reducing overall treatment costs.
