Embodiment Construction
[0034] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
[0035] In order to solve the problem that the existing curved display device is prone to breakage at the bending point, resulting in bright lines, the embodiment of the present invention provides a display module, which ensures that at the bending position of the display panel, the bending area and the panel area The reliability of the connection between them can reduce the bending stress at the bending position, so as to avoid the occurrence of bending fracture and the problem of bright lines.
[0036] The display module described in one of the embodiments of the present invention, such as figure 1 with figure 2 shown, including:
[0037] The display panel 100 includes a flexible base substrate 101 and an inorganic material layer 102 located on the f...

The invention provides a display module and a display device, and is applied to the technical field of display. The module comprises a display panel, the display panel comprises a flexible substrate and an inorganic material layer, the inorganic material layer comprises a slotting area penetrating to the substrate, and the slotting area is filled with an organic material layer to form a bending area; the display panel further comprises a first area; a contact area of the inorganic material layer on the first area and the organic material layer of the bending area forms a first connection area; a first back film, at least one part of the bending area extends out of the first end face of the first back film and bends and extends in the direction away from the first end face; the orthographic projection of the first connecting area on the plane where the first back film is located is located on the first back film; and a protective layer which is arranged on one side, deviating from the first back film, of the first area, covers the bending area and extends to cover the whole first connecting area. According to the display module, by setting the relative position relation among the back film, the protective layer and the first connecting area, the problem of bright lines caused by bending breakage can be avoided.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] With the development of flexible display technology, curved display has become a major development trend in the current display field. In addition to curved screens, folding screens are also one of the display structures for curved displays, and achieving bending or even folding is currently a difficult point in the design of curved display panels. [0003] In the existing technology, the folding screen is pulled due to the force at the bending point, and there is a dislocation of the connecting layer, or a bending fracture occurs, which causes the problem of bright lines and affects the performance and display effect of the display product. The structure is improved to solve this technical problem. Contents of the invention [0004] The purpose of the technical solution of the present invention is ...
