Abstract

The invention provides a flexible OLED display device and a preparation method of a module laminated structure of the flexible OLED display device. The preparation method comprises steps that a back plate is stripped from a display panel through a heating process, a foam layer is used for replacing the back plate to be attached to the display panel, in this way, the flexible OLED display device without the back plate can be manufactured, and the foam layer can further support and protect the display panel, so the requirement that the flexible OLED display device is lighter and thinner can be met under the condition that the display panel is not damaged.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a flexible OLED display device and a module stacked structure thereof. Background technique [0002] Compared with liquid crystal display (liquid crystal display, LCD) panels, organic light-emitting diode (organic light-emitting diode, OLED) flexible panels have many advantages such as simple structure, bendability, self-illumination, and fast response speed. Therefore, OLED flexible panels have gradually attracted everyone's attention. However, there are still some defects in the manufacturing process of OLED flexible panels, and OLED technology is not mature enough, so many processes still need to be gradually improved. [0003] Currently, in the module stacking manufacturing stage of flexible OLED display devices, a glass cover plate is peeled off from a display panel by a laser liftoff (LLO) process, and a back plate is attached to the display panel. ...
