Description

Technical Field

[0001] The present invention relates to the technical field of display modules, and particularly to a mounting structure adapted to a narrow-edge display module. Background Art

[0002] When manufacturing a display screen device, during its assembly process, a display module for controlling the light display function needs to be mounted on a backlight source. The mounting method generally uses an adhesive method. In order not to affect the light-emitting area of the backlight source, the adhesive area is only limited to the edge of the display module. And in order to ensure that the light-emitting direction of the backlight source is only limited to the direction perpendicular to the display module, the adhesive structure should also ensure that after the backlight source and the display module are adhered, light will not leak from the side of the adhesive joint.

[0003] In the prior art, the conventional method is to stack the adhesive layer between the connection of the backlight source and the display module. However, with the upgrade of display technology, narrow-bezel display devices have gradually become the mainstream. Therefore, the thickness of the adhesive layer is further reduced, resulting in a decrease in adhesive stability and affecting the product yield. For the problem of difficult adhesive assembly of narrow-bezel display devices, the prior art proposes a solution to use side adhesives instead of stacked adhesives. However, setting adhesives only on the side will cause a decrease in the tensile strength of the laminate in the vertical direction, and it is easy to cause gaps or spaces between layers under the action of pulling or swelling forces formed in the vertical direction, resulting in problems such as poor display or layer damage. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a mounting structure adapted to a narrow-edge display module, which can effectively solve the deficiencies in the above prior art.

[0005] A mounting structure adapted to a narrow-edge display module includes:

[0006] A display module, which includes a lower polarizer, a display control unit, and an upper polarizer stacked in sequence from bottom to top;

[0007] A backlight module, which includes a backlight source structure abutted against the side of the lower polarizer away from the upper polarizer and a backlight frame covering the backlight source structure;

[0008] Wherein, on the side of the backlight frame facing the lower polarizer, there is a flat section, a first inclined section arranged on the flat section facing the backlight source structure, and a second inclined section arranged on the side of the flat section away from the first inclined section. The inclination angle of the first inclined section is 20° - 48°, and the inclination angle of the second inclined section is 50° - 70°;

[0009] A glue colloid, which is used to connect the display module and the backlight module. The glue colloid includes a first glue part and a second glue part connected to the first glue part. The first glue part is pasted on the flat section, the first inclined section, the second inclined section, and the side of the lower polarizer away from the upper polarizer. The second glue part is pasted on the upper polarizer, the display control unit, the lower polarizer, the first glue part, and the backlight frame.

[0010] Furthermore, the projected area of the upper polarizer on the display control unit is larger than the projected area of the lower polarizer on the display control unit, and the projected area of the display control unit on the upper polarizer is equal to the projected area of the lower polarizer on the upper polarizer.

[0011] Furthermore, the second glue part is pasted on the side of the upper polarizer facing the lower polarizer.

[0012] Furthermore, the projected area of the lower polarizer on the upper polarizer is equal to the projected area of the backlight frame on the upper polarizer.

[0013] Furthermore, the width of the second glue part gradually decreases from the upper polarizer towards the backlight frame.

[0014] Furthermore, the inclination angle of the first inclined section is specifically 35° - 45°.

[0015] Furthermore, the inclination angle of the second inclined section is specifically 56° - 65°.

[0016] Furthermore, the first glue part is transparently arranged.

[0017] Furthermore, the second glue part is opaquely arranged.

[0018] Furthermore, a reflection unit is arranged on the first inclined section, and the reflection unit is a mirror.

[0019] The beneficial effects of the present invention are as follows: By pasting the first adhesive part on the flat section, the first inclined section, the second inclined section, and the side of the lower polarizer away from the upper polarizer, and by pasting the second adhesive part on the upper polarizer, the display control unit, the lower polarizer, the first adhesive part, and the backlight frame, the cross-sectional view of the first adhesive part and the second adhesive part connected to the first adhesive part is in a T shape, so that bonding in the vertical direction can be achieved even in the case of a narrow border, avoiding the decrease in the tensile strength in the vertical direction caused by only using side bonding, which easily leads to the formation of gaps or spaces between layers under the action of pulling or swelling forces formed in the vertical direction, resulting in problems such as poor display or layer damage; By providing a flat section on the side of the backlight frame facing the lower polarizer, a first inclined section of the flat section facing the backlight structure, and a second inclined section on the side of the flat section away from the first inclined section, while reducing the thickness of the first adhesive part, the pasting area of the first adhesive part can be increased, saving space, enabling the overall thickness of the assembled display device to be controlled to a relatively thin level, meeting the overall assembly requirements, and avoiding the decrease in bonding stability affecting the product yield rate; BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiment 1

[0029] Please refer to Figures 1 to 2 , the fitting structure adapted to the narrow-edge display module in the embodiment of the present invention includes:

[0030] A display module 10, the display module 10 includes a lower polarizer 11, a display control unit 12, and an upper polarizer 13 which are stacked in sequence from bottom to top;

[0031] A backlight module 20, the backlight module 20 includes a backlight source structure 21 abutted against one side of the lower polarizer 11 away from the upper polarizer 13 and a backlight frame 22 covering the backlight source structure 21;

[0032] Wherein, a flat section 23 is provided on one side of the backlight frame 22 facing the lower polarizer 11, a first inclined section 24 provided on the flat section 23 facing the backlight source structure 21, and a second inclined section 25 provided on one side of the flat section 23 away from the first inclined section 24. The inclination angle of the first inclined section 24 is 20° - 48°, and the inclination angle of the second inclined section 25 is 50° - 70°;

[0033] An adhesive colloid 30, the adhesive colloid 30 is used to connect the display module 10 and the backlight module 20. The adhesive colloid 30 includes a first adhesive part 31 and a second adhesive part 32 connected to the first adhesive part 31. The first adhesive part 31 is pasted on the flat section 23, the first inclined section 24, the second inclined section 25, and one side of the lower polarizer 11 away from the upper polarizer 13, and the second adhesive part 32 is pasted on the upper polarizer 13, the display control unit 12, the lower polarizer 11, the first adhesive part 31, and the backlight frame 22.

[0034] Further, the projected area of the upper polarizer 13 on the display control unit 12 is larger than the projected area of the lower polarizer 11 on the display control unit 12, and the projected area of the display control unit 12 on the upper polarizer 13 is equal to the projected area of the lower polarizer 11 on the upper polarizer 13.

[0035] Further, the second adhesive part 32 is pasted on one side of the upper polarizer 13 facing the lower polarizer 11.

[0036] Further, the projected area of the lower polarizer 11 on the upper polarizer 13 is equal to the projected area of the backlight frame 22 on the upper polarizer 13.

[0037] It should be noted that, in this embodiment, the first adhesive portion 31 is adhered to the flat section 23, the first inclined section 24, the second inclined section 25, and the side of the lower polarizer 11 away from the upper polarizer 13, and the second adhesive portion 32 is adhered to the upper polarizer 13, the display control unit 12, the lower polarizer 11, the first adhesive portion 31, and the backlight frame, wherein the second adhesive portion 32 is adhered to the side of the upper polarizer 13 facing the lower polarizer 11, and the second adhesive portion 32 is adhered to the outside of the display control unit 12, the lower polarizer 11, the first adhesive portion 31, and the backlight frame 22.

[0038] It can be understood that by adhering the first adhesive portion 31 to the flat section 23, the first inclined section 24, the second inclined section 25, and the side of the lower polarizer 11 away from the upper polarizer 13, and by adhering the second adhesive portion 32 to the upper polarizer 13, the display control unit 12, the lower polarizer 11, the first adhesive portion 31, and the backlight frame, wherein the second adhesive portion 32 is adhered to the side of the upper polarizer 13 facing the lower polarizer 11, and the second adhesive portion 32 is adhered to the outside of the display control unit 12, the lower polarizer 11, the first adhesive portion 31, and the backlight frame 22, so that the cross-sectional view of the first adhesive portion 31 and the second adhesive portion 32 connected to the first adhesive portion 31 is in a T shape, enabling bonding in the vertical direction even in the case of a narrow border, avoiding a decrease in the tensile strength in the vertical direction caused by only using side bonding, which easily leads to the formation of gaps or spaces between layers under the action of tensile or expansion forces formed in the vertical direction, resulting in problems such as poor display or layer damage; by providing the flat section 23 on the side of the backlight frame 22 facing the lower polarizer 11, the first inclined section 24 on the flat section 23 facing the backlight structure 21, and the second inclined section 25 on the side of the flat section 23 away from the first inclined section 24, while reducing the thickness of the first adhesive portion 31, the bonding area of the first adhesive portion 31 can be increased, saving space, enabling the overall thickness of the assembled display device to be controlled to a relatively thin level, meeting the overall assembly requirements, and avoiding a decrease in bonding stability that affects the product yield.

[0039] Further, the inclination angle of the first inclined section 24 is specifically 35° - 45°.

[0040] Furthermore, the inclination angle of the second inclined section 25 is specifically 56°-65°.

[0041] It should be noted that the arrangements of the first inclined section 24 and the second inclined section 25 can enable the first adhesive part 31 to have a certain expansion volume at this position to increase the contact area with the adhesion surface.

[0042] It can be understood that by setting the angle of the second inclined section 25 to be greater than that of the first inclined section 24, on the one hand, it is convenient to guide the first adhesive part 31 into the flat section 23 and the first inclined section 24 during assembly, thereby improving the assembly efficiency. On the other hand, the design of setting the angle of the second inclined section 25 to be greater than that of the first inclined section 24 can well buffer and disperse the longitudinal pulling stress on the adhesive body, playing a role in firm connection.

[0043] Furthermore, the width of the second adhesive part 32 gradually decreases from the upper polarizer 13 towards the backlight frame 22.

[0044] It can be understood that by setting the width of the second adhesive part 32 to gradually decrease from the upper polarizer 13 towards the backlight frame 22, the occupied space of the second adhesive part 32 can be reduced.

[0045] Furthermore, the first adhesive part 31 is transparently arranged.

[0046] Furthermore, the second adhesive part 32 is opaquely arranged.

[0047] It can be understood that by setting the first adhesive part 31 transparently and the second adhesive part 32 opaquely, the second adhesive part 32 plays a light-shielding role on the side, while the first adhesive part 31 is pasted on the flat section 23, the first inclined section 24, the second inclined section 25, and the side of the lower polarizer 11 away from the upper polarizer 13, serving the purpose of allowing the light emitted by the backlight structure to pass through, so as to minimize the loss of the light emitted by the backlight structure and improve the display effect.

[0048] Furthermore, a reflection unit 26 is arranged on the first inclined section 24, and the reflection unit 26 is a mirror.

[0049] It can be understood that by arranging the reflection unit 26 on the first inclined section 24 and reflecting part of the light reflected by the display module 10 to the first inclined section 24 through the angle design of the first inclined section 24, the light can be "re-concentrated and re-used", improving the light-emitting display effect.

[0050] In summary, for the assembly structure adapted to the narrow-edge display module in the above embodiments of the present invention, by pasting the first adhesive part on the flat section, the first inclined section, the second inclined section, and the side of the lower polarizer away from the upper polarizer, and by pasting the second adhesive part on the upper polarizer, the display control unit, the lower polarizer, the first adhesive part, and the backlight frame, the first adhesive part and the second adhesive part connected to the first adhesive part are in a T shape, so that bonding in the vertical direction can be achieved even in the case of a narrow frame, avoiding the decrease in the tensile strength in the vertical direction caused by only using side bonding, which easily leads to the formation of gaps or spaces between layers under the action of the pulling or swelling force formed in the vertical direction, resulting in problems such as poor display or layer damage; by providing a flat section on the side of the backlight frame facing the lower polarizer, a first inclined section of the flat section facing the backlight structure, and a second inclined section on the side of the flat section away from the first inclined section, while the thickness of the first adhesive part is reduced, the bonding area of the first adhesive part can be increased, saving space, enabling the overall thickness of the assembled display device to be controlled to a relatively thin level, meeting the overall assembly requirements, and avoiding the decrease in bonding stability affecting the product yield.
