Fig. 1 is a schematic structural view of an exemplary flat display module, and fig. 2 is a schematic structural view of an exemplary curved display module. As shown in fig. 1, the exemplary display module has a display area AA and a peripheral area FA surrounding the display module. The display module comprises a display panel 10, an adhesive layer 20, an ink layer 30 and a cover plate 40 which are sequentially stacked. Wherein, the first surface and the second surface of the cover plate 40 along the thickness direction are plane. The ink layer 30 includes a first sub-ink structure 31 and a second sub-ink structure 32 that are stacked, where the length of the first sub-ink structure 31 away from the edge of the cover plate is greater than the length of the second sub-ink structure 32 away from the edge of the cover plate, a height difference H1 exists between the first sub-ink structure 31 and the cover plate 40, a height difference H2 exists between the second sub-ink structure 32 and the cover plate 40, the height differences H1 and H2 are ink break differences, and the area covering the height differences H1 and H2 is the ink break difference area H. In the manufacturing process of the display module, the cover plate and the display panel are required to be attached through the colloid, in the attaching process, the colloid, the cover plate and the ink structure can form a cavity in the ink break zone, and under the effect of attaching pressure, the colloid can deform to fill the cavity and absorb residual gas in the cavity.

As shown in fig. 2, the display module includes a display panel 10, a glue layer 20, an ink layer 30 and a cover plate 40 sequentially stacked. Wherein, the first surface and the second surface of the cover plate 40 along the thickness direction are both curved surfaces.

Because the area and the appearance of the joint surface of the colloid are different from those of the joint surface of the cover plate, the colloid is required to deform so as to adapt to the joint surface of the cover plate, and the joint smoothness is ensured. In the laminating process of curved surface display module assembly, because the colloid originally is used for filling the deformability of printing ink offset district cavity and is dispersed, lead to the colloid unable original performance of full play, covering ability reduces, if the thickness of colloid in the curved surface display device is the same with the thickness of colloid in the plane display device, can't absorb the gas that remains in the cavity completely, finally form the bubble at printing ink offset district, only thicken the thickness of colloid, just can eliminate the bubble completely, but because the increase of colloid thickness, lead to the thickness of display module assembly also along with increasing.

In order to not change the thickness of the colloid in the curved surface display device, and also to eliminate the bubbles generated in the lamination process of the colloid and the cover plate, a first aspect of the embodiments of the present disclosure provides a display module having a display area and a peripheral area surrounding the display area, the display module includes: display panel, colloid and apron that the lamination set up in proper order. The cover plate is provided with a first surface and a second surface along the direction deviating from the display panel, the cover plate comprises a first main body part and a first peripheral part surrounding the first main body part, the first peripheral part is positioned in a peripheral area, and the first surface and the second surface of the first peripheral part are curved surfaces. The display module further comprises an ink structure which is arranged on one side of the cover plate facing the colloid, and the ink structure is attached to the first periphery; the ink structure, the colloid and the cover plate define a first cavity; the ink structure comprises: a first sub-ink structure and a second sub-ink structure are arranged in a lamination manner along a direction deviating from the first peripheral part; the second sub-ink structure is provided with an air guide channel which enables the first cavity to be communicated with the outside.

Through forming the air guide passageway at the printing ink layer, through the air guide passageway, the bubble that will produce at colloid laminating in-process discharges outside the display module assembly to this air guide passageway can also reduce the deformation of colloid at the laminating in-process, improves the gaseous covering ability of colloid after taking place deformation, avoids producing the bubble.
