The invention relates to an organic light-emitting display device. The organic light-emitting display device comprises a base plate; a pixel insulating column; an inorganic protecting layer covering the top and the side wall of the pixel insulating column; a pixel main body; an inorganic packaging layer covering the inorganic protecting layer and the pixel main body; and an organic packaging layercovering the inorganic packaging layer. The organic light-emitting display device is characterized that the top and the side wall of the pixel insulating column are covered by the inorganic protecting layer, the side face and the top of the pixel main body are covered by the inorganic protecting layer and an inorganic packaging film, namely the side face and the top of the pixel main body are inorganic material layers, so the pixel main body is surrounded by an inorganic material, thereby the pixel main body is not easily separated from the inorganic packaging film while bended. The product reliability is improved, and the flexibility performance is developed beneficially. The invention further provides a preparation method for the organic light-emitting display device, and an organic light-emitting display unit.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display device, a preparation method thereof, and an organic light-emitting display device. Background technique [0002] Organic light-emitting display has become the focus of research and development due to its flexible properties. [0003] At present, organic light-emitting displays are generally encapsulated by a thin film encapsulation process. The thin-film packaging process generally includes: after the main body of the pixel is formed, first cover the inorganic film layer, and then cover the inorganic film layer with the organic film layer; the inorganic film layer and the organic film layer together form the packaging film layer; the packaging film layer can block water. The role of oxygen, thereby preventing the erosion of water and oxygen on the main body of the pixel. [0004] However, after the current organic light-emitting display devic...
