Description

Display module and display device Technical Field The embodiment of the application relates to the technical field of display, in particular to a display module and a display device. Background With the rapid development of consumer electronics, the screen ratio of a display panel becomes one of the important indicators for measuring the competitiveness of the product. In order to pursue extremely narrow-frame and even borderless effects, flexible display module technology is widely used. The binding area of the display substrate is bent towards one side deviating from the cover plate, so that the non-display area of the display module is obviously reduced, the narrow frame design is realized, and the visual effect and the market competitiveness of the product are greatly improved. However, due to the extremely narrow frame, the distance between the frame in the whole machine and the fragile parts of the display substrate in the structures such as the bending area (Bending arc area) and the four corner area of the display substrate is greatly shortened. When the whole machine falls or is impacted, external impact force is directly transmitted to the glue injection layer filled between the middle frame and the display substrate through the middle frame, and then the glue injection layer acts on the bending arc area and the four corner area of the display substrate in a concentrated mode, so that cracks (crick) are easily generated on the display substrate at the weak position, and display abnormality and even functional failure are caused. Therefore, how to effectively improve the anti-falling impact capability of the display module while maintaining the advantages of the narrow frame is a technical problem to be solved in the field.
