Abstract
A flexible OLED display panel is disclosed and includes an encapsulation structure. The encapsulation structure includes: a first inorganic thin film formed on a surface of an OLED display layer and a surrounding region of the surface; a first organic thin film formed on a surface of the first inorganic thin film; and a plurality of dams. Each of the dams has a first sub-dam close to the first inorganic thin film and a second sub-dam away from the first inorganic thin film. A gap is formed between the first sub-dam and the second sub-dam which are located at a same side. The gap is filled with desiccant.
