[0041] The screen module comprising the curved portion needs to consider the fitting problem between the display body and the cover layer during the manufacturing process. Due to the difficulty in adapting the curvature of the display body and the cover layer, there are bubbles and black spots caused by wrinkles between the display body and the cover layer after fitting, which affects the overall aesthetics of the screen module. However, the solutions of optical adhesive expansion, optical adhesive thickness increase, and display body extrusion by structure not only have poor effect but also have the risk of damaging the display body.

[0042] The present disclosure provides a screen module, Figure 1is a schematic diagram of an assembly structure of a screen module in an example embodiment of the present disclosure, as shown in Figure 1 The screen module 1 includes a cover layer 12, a display body 11, and a first spray layer 13. The display body 11 is assembled to the inner side 121 of the cover layer 12, and the display body 11 includes an outer surface arranged towards the cover layer 12. In the corner area of the screen module 1, the inner side 121 includes a first curved structure 1211, and the outer surface includes a matching area 113. The first spray layer 13 is filled between the first curved structure 1211 and the matching area 113, and the first spray layer 13 includes a first side 131 matched with the matching area 113 and a second side 132 matched with the first curved structure 1211. The thickness of the first spray layer 13 decreases from the center of the corner area to the edge.

[0043] It should be noted that the thickness direction of the first spray layer 13 can be the same as the thickness direction of the screen module 1. The thickness direction of the planar area of the screen module 1 can be the direction perpendicular to the plane, and the thickness direction of the curved part of the screen module 1 can be the direction perpendicular to the tangent plane at the current position. The center of the corner area can refer to the geometric center of the corner area of the screen module 1. The thickness of the first spray layer 13 can decrease linearly, curvilinearly, or in steps from the center of the corner area to the edge. The present disclosure does not limit this.

[0044] The first spray layer 13 is filled between the cover layer 12 and the display body 11. The first spray layer 13 forms the first side 131 matched with the matching area 113 of the display body 11 and the second side 132 matched with the first curved structure 1211 of the cover layer 12. The thickness of the first spray layer 13 decreases from the center of the corner area of the screen module 1 to the edge to adapt to the bottom space formed by the first curved structure 1211, avoiding the appearance problems such as bubbles, wrinkles, and black spots caused by the display body 11 failing to adapt to the bottom space formed by the first curved structure 1211 with large curvature in the corner area of the screen module 1. The display body 11 and the cover layer 12 in the corner area of the screen module 1 can obtain the expected matching effect with the help of the first spray layer 13, improving the production yield and reducing the bonding cost of the display body 11 and the cover layer 12. The screen module 1 with excellent bonding effect can be mass-produced at a reasonable price and popularized to general models. In addition, the screen module 1 reduces the requirements and influence on the packaging technology, and reduces the requirements on the bonding equipment of the 3D guide film and the material requirements on the optical adhesive layer.

[0045] It should be noted that the screen module 1 can be a curved screen or a flexible screen. The screen module 1 can be an OLED-based display screen or an LCD display screen, and the present disclosure does not limit this.

[0046] In some embodiments, asFigure 2 As shown in the figure, the first spray layer 13 is formed on the first curved structure 1211 to obtain the first side surface 131 matched with the matching area 113 which is attached to the first side surface 131 through the optical adhesive layer. That is, the filler material is sprayed on the first curved structure 1211 of the cover plate layer 12 to form the first spray layer 13, and the first side surface 131 is obtained after the formation of the first spray layer 13. Generally, the curvature of the inner side surface 121 of the cover plate layer 12 corresponding to the curved portion of the screen module 1 is large, and the first side surface 131 reduces the curvature to match the matching area 113 of the display body 11, avoiding the modification of the display body 11, and helping to achieve the expected attachment effect between the cover plate layer 12 and the display body 11.

[0047] In other embodiments, as shown in the figure, the first spray layer 13 is formed on the matching area 113 to obtain the second side surface 132 matched with the first curved structure 1211 which is attached to the second side surface 132 through the optical adhesive layer. That is, the filler material is sprayed on the matching area 113 of the display body 11 to form the first spray layer 13, and the second side surface 132 is obtained after the formation of the first spray layer 13. Generally, the curvature of the inner side surface 121 of the cover plate layer 12 corresponding to the curved portion of the screen module 1 is large, and the first spray layer 13 of different thickness can adapt to the bottom space formed by the first curved structure 1211 in the process of attaching to the inner side surface 121 of the cover plate layer 12, and also can achieve the expected attachment effect between the cover plate layer 12 and the display body 11. Figure 3 In the above embodiments, as shown in the figure, the display body 11 and the cover plate layer 12 formed with the first spray layer 13 can be attached through the conventional optical adhesive layer, without the need to thicken or expand the optical adhesive layer to avoid the interference and extrusion of the structure of the display body 11. As shown in the figure, the cover plate layer 12 and the display body 11 formed with the first spray layer 13 can be directly attached by the adhesion of the first spray layer 13, or attached through the conventional optical adhesive layer, without the need to thicken or expand the optical adhesive layer to avoid the interference and extrusion of the structure of the display body 11.

[0048] Figure 2 Figure 3

[0049] The spraying process can use the coordinate range, walking range and thickness range of the spraying equipment to spray at any position, in any shape and with any thickness. As shown in the figure, taking the first spray layer 13 formed on the matching area 113 of the display body 11 as an example, local spraying is performed in the inkjet mode at the position of the matching area 113, and the thickness of the first spray layer 13 decreases from the center to the edge of the corner area of the screen module 1 to form a second side surface 132 in the form of a stepped, curved structure or inclined surface. Figure 4

[0050] ​​​​From the whole, the first spray layer 13 is formed at the matching area 113 as a whole, the tangent angle of the end of the whole and the plane is α, α can match the first curved structure 1211 of the cover plate layer 12, and then the display body 11 is implemented. The problem of black spots and bubbles can be solved, the screen module 1 at the curved part presents a round feeling and can be used for display.

[0051] In the spraying process, for example Figures 5-9 As shown, the thickness can be controlled by changing the color tone of the formed image, and the thickness of the first spray layer 13 can be obtained according to the curvature requirement of the first side 131 or the second side 132, and the spray color tone at different positions can be obtained according to the thickness. In the spraying operation, the spraying process can be completed according to the spray color tone information at different positions. For example Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 may correspond to the coating profile of the four rows of image color tones from top to bottom in Figure 5 respectively.

[0052] It should be noted that the refractive index of the first spray layer 13 and the optical glue layer can be the same, so as to ensure that the optical properties at the first spray layer 13 are consistent with the optical properties of other positions of the screen module 1, and the light will not produce additional refraction and reflection at the curved part of the screen module 1.

[0053] In the above embodiment, the matching area 113 can include a second curved structure 1131, and the first side 131 includes a curved surface with the same curvature as the second curved structure 1131. That is, the matching area 113 of the display body 11 can have the second curved structure 1131, and the first side 131 can be formed on the second curved structure 1131 or matched with the second curved structure 1131.

[0054] Further, the matching area 113 can further include a first plane 1132, and the first side 131 includes a plane matched with the first plane 1132. That is, the matching area 113 of the display body 11 can have the first plane 1132, and the first side 131 can be formed on the first plane 1132 or matched with the first plane 1132.

[0055] In the above embodiment, the inner side 121 of the cover plate layer 12 can further include a second plane 1212 connected with the first curved structure 1211, and the outer surface can further include a third plane connected with the matching area 113, the screen module 1 includes a second spray layer connected with the first spray layer 13, and the second spray layer is filled between the second plane 1212 and the third plane. That is, in addition to the first curved structure 1211, the first spray layer 13 can also be formed on the second plane 1212 of the inner side 121 or on the third plane, so as to improve the smoothness of the matching between the cover plate layer 12 and the display body 11.

[0056] In the above embodiment, the display body 11 comprises a display functional layer 111 and an encapsulation layer 112, and the encapsulation layer 112 encapsulates the display functional layer 111 to achieve encapsulation of the display functional layer 111. The encapsulation layer 112 can be a thin film encapsulation layer 112 or a glass encapsulation layer 112.

[0057] When the encapsulation layer 112 comprises two inorganic thin film layers and an organic thin film layer between the two inorganic thin film layers, thin film encapsulation can be achieved, and the encapsulation effect and the thinness of the screen module 1 are improved.

[0058] In some embodiments, the screen module 1 can comprise four corner regions, and the display body 11 is assembled to the inner side of the cover layer 12 to form a four-curved screen.

[0059] Alternatively, the screen module can also be a flexible screen, and the corner region of the flexible screen can refer to a region of the flexible screen that can be bent.

[0060] The present disclosure further provides an electronic device comprising the above screen module 1.

[0061] The first spray layer 13 is filled between the cover layer 12 and the display body 11, the first spray layer 13 forms a first side surface 131 matched with the matching region 113 of the display body 11 and a second side surface 132 matched with the first curved structure 1211 of the cover layer 12, and the thickness of the first spray layer 13 decreases from the center to the edge of the corner region of the screen module 1 to adapt to the bottom space formed by the first curved structure 1211, thereby avoiding appearance problems such as bubbles, wrinkles, and black spots caused by the display body 11 failing to adapt to the bottom space formed by the first curved structure 1211 with large curvature in the corner region of the screen module 1, so that the display body 11 and the cover layer 12 can obtain the expected matching effect in the corner region of the screen module 1 with the help of the first spray layer 13.
