Method of manufacturing a flexible organic light-emitting diode (OLED) display panel by laser lift-off of a glass carrier through a planarization layer

A method of manufacturing a flexible OLED display panel, comprising

• providing a glass carrier, sequentially forming a flexible substrate, a low temperature poly-Si layer and an OLED element layer on a surface of the glass carrier;
• forming a planarization layer on a second surface of the glass carrier which is away from the flexible substrate and obtaining a planarized OLED display panel;
• removing the glass carrier by laser lift-off the planarized OLED display panel, and obtaining the flexible OLED display panel;
• sequentially forming a packaging protecting layer, a flexible rear cover on the OLED element layer, the flexible substrate and the flexible rear cover forming an enclosed space for accommodating the OLED element layer and the packaging protecting layer;
• and
• forming a touch wire on the flexible substrate;
• or forming a first blocking layer on the flexible substrate, and forming the touch wire on the first blocking layer.
