Abstract

The application provides a display module and a display device. The display module includes a flexible display panel; a functional layer arranged on the flexible display panel; a thermosetting resin layer arranged on one side of the flexible display panel; a polymer electric heating film , arranged on the side of the thermosetting resin layer away from the flexible display panel; wherein, the hardness of the thermosetting resin layer changes with the temperature of the polymer electrothermal film. This application uses a combination of a thermosetting resin layer and a polymer electric heating film under the flexible display panel. The polymer electric heating film is connected to the power input module on the reel through the power module. When the temperature of the polymer electric heating film rises to the preset temperature value, the thermosetting resin layer is cured, and the hardness of the thermosetting resin layer increases, thereby enhancing the hardness and flatness of the flexible display panel during use, and maintaining the flatness of the flexible display panel.

Description

A display module and display device technical field [0001] The present application relates to the field of display technology, and in particular, to a display module and a display device. Background technique [0002] With the development of the times, high-performance electronic products have brought forth new ones, thin, flexible and bendable consumer electronics. The products have attracted the investment and development of various major manufacturers. Among them, the active matrix organic light emitting diode (AMOLED) has high contrast, Features such as wide viewing angle, fast response speed, and flexibility are expected to outlaw liquid crystals and become the mainstream choice for next-generation displays. select. [0003] At present, the rollable flexible panels include glass cover plates, polarizers, display panels, backplanes and other materials. After unfolding, because the lower part of the flexible panel is less rigid, when it is in a curled state for a lo...
