Patent number: 10472276Abstract: A composition for forming film having wrinkle structure and a method of forming the film are disclosed. The composition includes photo-curable agent and photoinitiator dissolved in the photo-curable agent. The cut off wavelength of light transmittance of the photo-curable agent is greater than the cut off wavelength of light absorbance of the photoinitiator. Photo-cured thin film is formed at the upper portion of composition layer at an initial time period of irradiation. By subsequent contraction, the photo-cured thin film forms wrinkles. The wrinkle structure is controlled by the relation of the cut off wavelength of light transmittance of the photo-curable agent and the cut off wavelength of light absorbance of the photoinitiator, the photo-curing rate of the composition and the thickness of the composition layer, and the photoinitiator concentration, etc., before photo-curing. The film may increase the emission efficiency of LED and OLED and the sensing effect of sensor.Type: GrantFiled: August 10, 2015Date of Patent: November 12, 2019Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Seung Koo Park, Jaehyun Moon, Jeong Ik Lee, Byoung Gon Yu, Jonghee Lee, Chul Woong Joo, Doo-Hee Cho, Jun-Han Han
