Patent number: 10297648Abstract: The disclosure discloses an Organic Light-Emitting Diode (OLED) display, a method for fabricating the same, and a display device, where a color filter layer is used as an insulation layer between electrically conductive layers in a touch electrode structure, so that the insulation layer and the color filter layer are the same film layer, thereby improving the integrity of the OLED display, and reducing the thickness of the OLED display. Also, the OLED display can be fabricated by forming the electrically conductive layers and the color filter layer in the touch electrode structure through inkjet printing, thereby preventing an organic light-emitting diode layer from being affected in an etching process. Therefore, at least one inorganic encapsulation layer can be arranged on a side of the touch electrode structure furthest away from the organic light-emitting structural layer to enable the touch electrode structure to be integrated in the OLED display.Type: GrantFiled: October 17, 2017Date of Patent: May 21, 2019Assignee: XIAMEN TIANMA MICRO-ELECTRONICS CO., LTD.Inventors: Jun Ma, Hanyu Gu
