Embodiment Construction
[0062] In order to further illustrate the cover plate, display module, and display device provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.
[0063] Such as Figure 1 to Figure 3 As shown, since the ink layer (such as the mark 20 ) is provided on the cover plate, the ink layer will produce a level difference, resulting in an uneven surface where the cover plate and the folding screen are bonded. When the cover plate is bonded to other structures included in the folding screen through the glue material 45, the part of the glue material 45 located in the overlapping area 44 is bonded to the ink layer, and the part of the glue material located in the filling area 43 is bonded to the periphery of the ink layer. Then, it is used to fill the level difference formed by the ink layer.
[0064] Such as image 3 and Figure 4As shown, if the thickness of the adhesive material is thin, the ef...

The invention provides a cover plate, a display module and a display device, relates to the technical field of display, and aims to solve the problem that when the cover plate is bonded with other structures included in a folding screen through a glue material, if the glue material is thin, bubbles are easily generated between the cover plate and the other structures, and the display effect of the folding screen is affected. And if the thickness of the rubber material is relatively large, the folding performance of the folding screen is easily influenced. The cover plate comprises a cover plate body, a light shielding layer and a segment difference compensation layer, wherein the light shielding layer is located on the cover plate body; and the segment difference compensation layer and the shading layer are arranged on the same layer, and the thickness of the segment difference compensation layer is smaller than or equal to that of the shading layer in the direction perpendicular to the cover plate body. The cover plate provided by the invention is used for covering a display substrate to form a module structure.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a cover plate, a display module and a display device. Background technique [0002] In recent years, folding screens have attracted much attention due to their flexible and variable display methods. In order to realize the folding function, the cover selected for the folding screen needs to have both flexibility and certain strength. However, the current cover plate structure has the following problems: when the cover plate is bonded to other structures included in the folding screen through the adhesive material, if the thickness of the adhesive material is thin, it is easy to generate air bubbles between the cover plate and other structures, affecting The display effect of the folding screen. If the thickness of the adhesive material is thick, it will easily affect the folding performance of the folding screen. Contents of the invention [0003] The purpose of the present...
