Description

Display module and folding device Technical Field The application relates to the technical field of folding equipment, in particular to a display module and folding equipment. Background With the advancement of technology, large screen devices are becoming increasingly popular with consumers. In order to solve the problems of large size and inconvenient carrying of the traditional tablet equipment, folding equipment is generated. Along with the continuous development of the folding display module, the three-fold equipment becomes a development direction due to the large screen occupation ratio and convenient carrying. However, when the three-fold display module is folded, the two folding structures can be mutually influenced, so that the form of the folding structure in a folded state is asymmetric, the folding radius of the partial folding structure is smaller, and when the folding device falls or is extruded, the display module is easy to damage and lose efficacy, and the reliability is lower. Disclosure of Invention The embodiment of the application provides a display module and folding equipment, which are used for solving the problem of how to improve the reliability of the display module. In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme: In a first aspect, an embodiment of the present application provides a display module, where the display module has an unfolded state and a folded state. The display module includes a display panel and a support plate. The support plate is arranged on the non-display side of the display panel in a lamination mode and is fixed with the display panel, the support plate comprises a first flat plate part, a first bendable part, a second flat plate part, a second bendable part and a third flat plate part which are sequentially connected, the first bendable part comprises a first section, the first section comprises a first part and a second part which are connected, the first part is connected between the second part and the first flat plate part, when the display module is in a folding state, the first flat plate part and the third flat plate part are all in lamination arrangement with the second flat plate part, the first section is in an arc shape, at least one part of the first part and at least one part of the second part are in lamination arrangement along the thickness direction of the second flat plate part, and bending rigidity of the first part is smaller than that of the second part. Compared with the situation that the bending rigidity of the second part is the same as that of the first part, the bending rigidity of the second part is larger than that of the first part, the display module provided by the embodiment of the application can increase the curvature radius of each point on the second part when the display module is in a folded state, and further can increase the curvature radius of each point on the display panel of the corresponding part, so that the display panel is prevented from being damaged and failed due to the fact that the internal stress of the display panel is increased greatly due to the fact that folding equipment falls or is extruded. In some possible implementations of the first aspect, the first portion has a plurality of groups of first through holes, the second portion has a plurality of groups of second through holes, when the display module is in the unfolded state, the plurality of groups of first through holes are arranged at intervals along the first direction, the plurality of groups of second through holes are arranged at intervals along the first direction, and a distance between two adjacent groups of first through holes is smaller than a distance between two adjacent groups of second through holes along the first direction. The first direction is the direction from the first bendable portion to the second bendable portion. Therefore, the bending rigidity of the second part is increased by adjusting the distance between two adjacent groups of second through holes to be larger than the distance between two adjacent groups of first through holes, the first bendable part is not required to be subjected to additional structural design, and the design and manufacturing difficulty of the supporting plate are simplified. In addition, the distance between two adjacent groups of second through holes is increased, the strength of the second part can be increased, and the supporting reliability of the supporting plate on the display panel is further improved, so that the overall reliability of the display module is improved. In some possible implementations of the first aspect, when the display module is in the unfolded state, a distance between two adjacent sets of second through holes gradually increases along the first direction. Therefore, the strength of the second part can be gradually increased along the first direction while the bending rigidity of the secon
