Patent number: RE47578Abstract: An organic light emitting diode (OLED) and a method of manufacturing the same. An auxiliary layer comprising a high density metallic compound and an emission layer are formed by a laser induced thermal imaging (LITI) process. The LITI process reduces manufacturing costs and time by eliminating the need for a mask patterning process. The metallic compound has a density of 2 g/cm3 or greater to promote adhesion and improve interfacial planarization. This results in improved luminance uniformity (i.e. luminance mura) between pixels within an OLED display device.Type: GrantFiled: October 19, 2017Date of Patent: August 20, 2019Assignee: SAMSUNG DISPLAY CO., LTD.Inventors: Kyul Han, Sang-Woo Lee, Hyo-Yeon Kim, Hye-Yeon Shim, Heun-Seung Lee, Sang-Woo Pyo, Ji-Hwan Yoon
