Detailed Description
Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

In recent years, full-screen displays have become the mainstream design scheme in the display field and are favored by consumers. At present, the flexible characteristic of the flexible screen is mainly utilized to realize the full-screen, the edge of the flexible screen is bent to the back of the main body display area, the width of a frame of the flexible screen is further reduced, and the screen occupation ratio is improved.
At present, after a flexible display module is bent, a screen body is often fixed through a padding block to prevent the bending part from rebounding, but the padding block is formed by compounding multiple layers of materials, and the padding block is easy to delaminate and lose efficacy, so that the reliability of the display module is low; in addition, because the metal layer dyne value of the display module is low, the padding block can not be attached to the metal layer frequently, and the corresponding padding block attachment area on the metal layer needs to be protected particularly in the module manufacturing process, so that the cost and the operation are increased.
Based on the above problems, embodiments of the present invention provide a display module and a display device, which can not only improve the structural reliability of the display module, but also reduce the operation and cost in the module manufacturing process.
