During the assembly process of the display module, the four sides of the display panel 101 and the middle frame 102 are fixed by the light shielding tape 103. However, when the display module is deformed, the position where the display panel 101 and the middle frame 102 are connected by the light shielding tape 103 will generate mutual pulling stress, resulting in uneven force on the display panel 101, and further causing a difference in thickness between different areas of the substrates on both sides of the display panel 101, thereby causing poor display and uneven display problems, thereby causing poor display and uneven display of the display panel 101. In addition, the optical component 104 is located inside the middle frame 102. The optical component 104 is used to provide a light source with uniform brightness for the display panel 101. However, the light-shielding tapes 103 on the four sides of the display panel 101 and the middle frame 102 are easy to fall off, causing foreign particles to enter the middle frame 102, which will interfere with the uniform distribution of light by the optical component 104, thereby aggravating the uneven display and poor display.

[0030] In view of the above technical problems, an embodiment of the present invention provides a display module. Figure 2 is a structural schematic diagram of a display module provided by an embodiment of the present invention, Figure 3 yes Figure 2 The schematic diagram of the top view structure of the display module shown in FIG. Figure 2 and Figure 3 As shown, the display module includes a display panel 10 and a middle frame 20. The display panel 10 includes a first sub-portion 11 and a second sub-portion 12, the second sub-portion 12 surrounds the first sub-portion 11, the first sub-portion 11 is located in the display area of ​​the display panel 10, and the second sub-portion 12 is located in the non-display area of ​​the display panel 10; the middle frame 20 includes a first accommodating groove 21, the first accommodating groove 21 at least partially surrounds the display panel 10, and at least a portion of the second sub-portion 12 is embedded in the first accommodating groove 21.

[0031] Specifically, the display module includes a display panel 10 and a middle frame 20. The display panel 10 includes a first subsection 11 and a second subsection 12, the second subsection 12 surrounds the first subsection 11, the first subsection 11 is located in the display area of ​​the display panel 10, the display area is the image display area of ​​the display panel 10, and the second subsection 12 is located in the non-display area of ​​the display panel 10, the non-display area is the area in the display panel 10 where the driving circuit can be placed. The middle frame 20 includes a first receiving groove 21, and no adhesive such as glue is required to be set in the first receiving groove 21. The first receiving groove 21 at least partially surrounds the display panel 10. The structure of the first receiving groove 21 can effectively reduce the influence of external force on the display panel 10, and avoid the display panel 10 being uneven and poor due to being pulled by external force. At least part of the second section 12 is embedded in the first receiving groove 21 . The second section 12 surrounds the first section 11 . The first section 11 does not need to be embedded in the first receiving groove 21 , thereby ensuring that the display area of ​​the first section 11 can fully display the image without being blocked.

[0032] The technical solution in the embodiment of the present invention is that the display module includes a display panel and a middle frame, the display panel includes a first sub-section and a second sub-section, the second sub-section surrounds the first sub-section, the first sub-section is located in the display area of ​​the display panel, and the second sub-section is located in the non-display area of ​​the display panel, and the middle frame includes a first receiving groove, the first receiving groove at least partially surrounds the display panel, and at least part of the second sub-section is embedded in the first receiving groove. The embodiment of the present invention uses the first receiving groove to surround the display panel, which solves the problem of generating a pulling force by directly connecting the display panel and the middle frame through a light-shielding tape, resulting in uneven force on the display panel, and further causes a difference in thickness between different areas of the substrates on both sides of the display panel, thereby causing poor display and uneven display problems, reducing the influence of external forces on the display panel, and can effectively improve the poor display and uneven display of the display module, and improve the image quality of the display module.

[0033] Optionally, Figure 4 is a schematic diagram of the structure of another display module provided by an embodiment of the present invention, such as Figure 4 As shown, the display module also includes a cover plate 30, which is located on the light-emitting side of the display panel 10; the vertical projection of the middle frame 20 on the plane where the cover plate 30 is located is located in the area where the cover plate 30 is located, and at least part of the surface of the middle frame 20 opposite to the cover plate 30 is bonded by a glue material 40.

In the case where the vertical projection area of ​​the cover plate 30 is less than or equal to the vertical projection area of ​​the middle frame 20, the glue material 40 is easy to fall off after bonding, thereby causing the closed space formed inside the middle frame 20 to be destroyed. At least a portion of the second section 12 of the display panel 10 is embedded in the first accommodating groove 21. No adhesive such as glue is required in the first accommodating groove 21. At least a portion of the surface of the middle frame 20 facing the cover plate 30 is bonded by the adhesive material 40. This can avoid directly bonding at least a portion of the surface of the display panel 10 facing the middle frame 20 by the adhesive material 40, and can also achieve connection between the four sides of the middle frame 20 and the cover plate 30, thereby preventing foreign particles from entering the internal area of ​​the middle frame 20.
