It can be understood that, by providing the detachably connected protective bracket 20 on the display panel 10, the protective bracket 20 includes a bracket main body 201, an adhesive portion 202 and a supporting portion 203 respectively connected with the bracket main body 201, the bracket main body 201 covers the driving chip 101 and the component 102, the adhesive portion is adhered to the back plate through the buffer adhesive layer 204, and the supporting portion 203 is abutted against the display panel 10; the area of buffer bonding layer 204 is greater than the area of bonding portion 202, in the direction of perpendicular display panel 10, the projection of bonding portion 202 is located the projection region of buffer bonding layer 204 for buffer bonding layer 204' S edge is expanded outward for bonding surface S2 of bonding portion 202 laminating display panel 10, and protection support 20 also can protect components and parts 102 and driver chip 101 on the display panel 10 from external force damage, and simultaneously when protection support 20 tears, the buffer bonding layer 204 that expands outward can play the cushioning effect, prevents the copper foil 103 on the protection support 20 extrusion display panel 10 backplate, prevents to produce the impression on copper foil 103 in the tearing process, has guaranteed the display effect of display module assembly.
In an embodiment, the buffer adhesive layer 204 includes a first adhesive layer 2041 and a second adhesive layer 2042 that are stacked, the first adhesive layer 2041 is connected to the adhesive portion 202, the second adhesive layer 2042 is adhered to the display panel 10, the area of the second adhesive layer 2042 is larger than the area of the first adhesive layer 2041, the first adhesive layer 2041 is a double-sided adhesive layer, the second adhesive layer 2042 is a single-sided adhesive layer, and the adhesive surface of the second adhesive layer 2042 is adhered to the back plate.
Specifically, the first adhesive layer 2041 and the second adhesive layer 2042 are adhered to each other, and as shown in fig. 5 and 9, the protective bracket 20 is adhered to the display panel 10 in the order of the adhesive portion 202, the first adhesive layer 2041, the second adhesive layer 2042, and the display panel 10.
Specifically, the first adhesive layer 2041 may be a double-sided adhesive, the second adhesive layer 2042 may be a single-sided foam adhesive, the thickness of the double-sided adhesive is 0.2mm, and the thickness of the single-sided foam adhesive is 0.4mm.
Specifically, the area of the first adhesive layer 2041 may be equal to the area of the adhesive surface S2, or may be smaller than the area of the adhesive surface S2, that is, the front projection of the first adhesive layer 2041 on the display panel 10 falls within the front projection of the adhesive surface S2 on the display panel 10.
Specifically, when the first adhesive layer 2041 and the second adhesive layer 2042 are provided, the adhesive capacity between the first adhesive layer 2041 and the second adhesive layer 2042 can be smaller than the adhesive capacity between the second adhesive layer 2042 and the display panel 10 by selecting appropriate materials, so that when the protective bracket 20 is torn, the protective bracket 20 can be removed by adopting smaller force, the extrusion force strength of the protective bracket 20 to the copper foil 103 during tearing is reduced, the buffer effect of the second buffer layer can be ensured as much as possible, and the yield of the display panel 10 is improved.
It can be appreciated that by providing the buffer adhesive layer 204 includes the first adhesive layer 2041 and the second adhesive layer 2042, the first adhesive layer 2041 and the second adhesive layer 2042 are stacked, wherein the first adhesive layer 2041 plays a role in double-sided adhesion, and the second adhesive layer 2042 plays a role in adhering the display panel 10 and buffering, so that the second adhesive layer 2042 that the protective bracket 20 expands outwards in use can play a role in buffering better.
In an embodiment, the thickness of the second adhesive layer 2042 is greater than the thickness of the first adhesive layer 2041 in a direction perpendicular to the display panel 10.
Specifically, the thickness of the first adhesive layer 2041 is greater than or equal to 0.05mm, preferably 0.05mm to 0.3mm, and may specifically be 0.2mm, but the thickness of the first adhesive layer 2041 is not limited to the above range, and may specifically be adjusted according to actual production conditions.
Specifically, the thickness of the second adhesive layer 2042 is greater than or equal to 0.3mm, and may be specifically 0.4mm, but the thickness of the second adhesive layer 2042 is not limited to the above range, and may be specifically adjusted according to actual production conditions.
Specifically, the thickness of the second adhesive layer 2042 is greater than that of the first adhesive layer 2041, the second adhesive layer 2042 is directly contacted with the display panel 10, the second adhesive layer 2042 plays a role in buffering and pasting, and the first adhesive layer 2041 only plays a role in pasting.
It can be appreciated that, since the second adhesive layer 2042 is attached to the display panel 10, the thickness of the second adhesive layer 2042 is greater than that of the first adhesive layer 2041, so that the second adhesive layer 2042 can be more uniformly dispersed when the protective frame 20 is torn and pulled, and the buffering effect is better.
In an embodiment, the front projection of the adhesive surface S2 of the adhesive portion 202 contacting the buffer adhesive layer 204 on the display panel 10 covers the front projection of the first adhesive layer 2041 on the display panel 10.
Specifically, the area of the first adhesive layer 2041, i.e. the double-sided adhesive layer, is set smaller than the area of the adhesive surface S2, so that the distance of the first adhesive layer 2041 shrinking inside the first adhesive layer 2041 is not displayed, and can be specifically adjusted according to actual production requirements.
It can be appreciated that by arranging the front projection of the bonding surface S2 on the display panel 10 to cover the front projection of the first adhesive layer 2041 on the display panel 10, when the protective bracket 20 is attached to the display panel 10, the adhesive layer is not overflowed, so that other impurities in the transportation process are prevented from adhering to the exposed adhesive material, and the connection of BA elements in the bonding area of the display panel 10 is affected.

It should be noted that, since the second adhesive layer 2042 may be a single-sided foam adhesive layer, the second adhesive layer 2042 has a limited thickness and is soft, and when the second adhesive layer 2042 is adhered to the display panel 10, the edge portion of the second adhesive layer 2042 is easy to curl, so that the adhesion between the protective bracket 20 and the display panel 10 is uneven, and the accuracy is low.
It can be appreciated that, as shown in fig. 8, by thinning the edge thickness of the second adhesive layer 2042, the vertical section of the second adhesive layer 2042 is trapezoidal, so that the probability of edge curling of the second adhesive layer 2042 can be reduced, and the accuracy of the second adhesive layer 2042 when being attached to the display panel 10 can be improved.
In the above embodiment, as shown in fig. 6 and 7, before the second adhesive layer 2042 is attached to the display panel 10, a release paper 2043 is covered on the adhesive side of the second adhesive layer 2042, and the release paper 2043 has a certain stiffness compared with the second adhesive layer 2042, so that the second adhesive layer 2042 can maintain a certain flatness.
In one embodiment, as shown in fig. 6 and 7, a distance between an edge of the front projection of the buffer adhesive layer 204 on the display panel 10 and an edge of the front projection of the adhesive portion 202 on the display panel 10 is greater than or equal to 2mm.
Specifically, in comparison with fig. 3 and 4, in fig. 4, the bonding portion 202 may include a bonding surface S2 and a buffer inclined surface (not shown) formed at the periphery of the bonding surface S2, so that the front projection of the bonding portion 202 on the display panel 10 may be greater than or equal to the front projection of the bonding surface S2 on the display panel 10.
Specifically, as shown in fig. 6 and 7, the distance between the edge of the front projection of the buffer adhesive layer 204 on the display panel 10 and the edge of the front projection of the adhesive portion 202 on the display panel 10 may be actually understood as a shortest distance between the outer contour of the buffer surface and the outer contour of the buffer adhesive layer 204 in the direction perpendicular to the display panel 10 is greater than or equal to 2mm.
It can be appreciated that by setting a reasonable outward expansion distance, when the display panel 10 and the protective support 20 are torn away, the protective support 20 can be torn away from any direction to disperse the extrusion force of the protective support 20 on the copper foil 103, so as to prevent the copper foil 103 from being stamped.
In an embodiment, the display panel 10 includes a binding area BA near the edge of the display panel 10, the component 102 is disposed on the binding substrate 104, the binding substrate 104 is located in the binding area BA, and the supporting portion 203 abuts against the binding substrate 104.
