Fig. 1 is a schematic diagram of a disassembled structure of a terminal device according to an embodiment of the present application, and in one embodiment, referring to fig. 1, the terminal device provided by the present application includes a middle frame 20 and a display screen 10 disposed on the middle frame 20. By way of example, the display screen 10 may be a 2D screen, a 2.5D screen, a 3D screen, a curved screen, a straight screen, a folded screen, or the like.

Specifically, the display screen 10 includes a display surface and a rear surface. The display surface is used for displaying information such as video, images and characters, the back is the side that the display screen 10 faces the middle frame 20, the back of the display screen 10 is fixedly arranged on the middle frame 20 through the first bonding layer 101, the first bonding layer 101 is arranged in the central area of the back of the display screen 10, and the area of the first bonding layer 101 is smaller than that of the display screen 10.

The central area on the back of the display screen 10 may be an area centered on the central point of the display screen 10; the central area of the display screen 10 may also be an area containing the center point of the display screen 10. The rear surface of the display panel 10 is an edge area except for the center area where the first adhesive layer 101 is located.

It will be appreciated that, referring to the cross-sectional view along the thickness direction of the display screen shown in fig. 2, the first adhesive layer 101 disposed at the first region of the back surface of the display screen 10 may have the first gap 104 between the edge region of the display screen 10 and the middle frame 20. When the terminal device falls, generally, the edge area of the display screen 10 is firstly landed, after the display screen 10 is impacted by the ground, the first gap 104 between the display screen 10 and the middle frame 20 can enable the edge area of the display screen 10 to have enough buffer space to vibrate along the thickness direction H of the display screen 10 after being impacted, so as to avoid breakage caused by direct collision between the edge area of the display screen 10 and the middle frame 20 with higher hardness.

Alternatively, the thickness of the first adhesive layer 101 ranges from 0.05mm to 0.5mm, the thickness of the first adhesive layer 101 determines the height of the first gap 104, and the thickness of the first adhesive layer 101 is set within a suitable range, so that the display screen 10 has a buffer space of a sufficient height to vibrate in the first gap 104 after being impacted.

Further, the area of the area where the first adhesive layer 101 is located is smaller than the area of the edge area of the display screen 10, and for example, the ratio of the area of the display screen 10 to the area of the first adhesive layer 101 may be greater than or equal to 4.

In the embodiment of the present application, the first adhesive layer 101 includes one or more first adhesive members 1011 arranged in a row. The first adhesive member 1011 may have a regular shape such as a circle, a square, an ellipse, a rectangle, a fan, or the like, or may have an irregular shape, or may have a combination of a plurality of shapes. The shape of the first adhesive 1011 is not limited in this application.

In one example, when the first adhesive layer 101 includes a first adhesive 1011, the area of the first adhesive 1011 is smaller than the area of the display 10, and in particular, the ratio of the area of the display 10 to the area of the first adhesive 1011 may be greater than or equal to 4.

For example, referring to fig. 3 and 4, assuming that the length of the display screen 10 in the X direction (i.e., the horizontal direction in fig. 3) is L, the height in the Y direction (i.e., the vertical direction in fig. 3) is H, referring to the first structural schematic view of the display screen shown in fig. 3, the display screen 10 is provided with a rectangular first adhesive member 1011 toward the center region of the side of the middle frame 20, the center of the first adhesive member 1011 is the center of the display screen 10, the length range of the first adhesive member 1011 may be greater than 0 and less than or equal to L/2, and the height range of the first adhesive member 1011 may be greater than 0 and less than or equal to H/2. Referring to a second structural schematic diagram of the display screen shown in fig. 4, a square first adhesive member 1011 is disposed on a side of the display screen 10 facing the middle frame 20, a center of a center region where the first adhesive member 1011 is located is not equal to a center of the display screen 10, a horizontal distance between a left edge of the first adhesive member 1011 and a left edge of the display screen 10 in an X direction may be greater than or equal to L/4, a horizontal distance between a right edge of the first adhesive member 1011 and a right edge of the display screen 10 in an X direction may be greater than or equal to L/4, a vertical distance between an upper edge of the first adhesive member 1011 and an upper edge of the display screen 10 in a Y direction may be greater than or equal to H/4, and a vertical distance between a lower edge of the first adhesive member 1011 and a lower edge of the display screen 10 in a Y direction may be greater than or equal to H/4, that is, both the length and the width of the square first adhesive member 1011 may be less than L/2.

In another example, when the first adhesive layer 101 includes a plurality of first adhesive pieces 1011 arranged in a row, the area of the first adhesive layer 101 is the sum of the areas of the plurality of first adhesive pieces 1011, and the thickness of each first adhesive piece 1011 is equal, the plurality of first adhesive pieces 1011 may be arranged in a center region of the side of the display screen 10 facing the middle frame 20 based on a predetermined pattern.

In this example, the first adhesive layer 101 may include a plurality of first adhesives 1011 each having the same shape and size. As an example, referring to the structural illustration three of the display screen shown in fig. 5, the first adhesive layer 101 includes two square first adhesives 1011, the two square first adhesives 1011 are arranged in a central area of the back surface of the display screen 10 in a horizontal direction based on a preset interval, wherein a horizontal distance between a left edge of the first adhesive 1011 located on the left side and a left edge of the display screen 10 in the X direction may be greater than or equal to L/4, a horizontal distance between a right edge of the first adhesive 1011 located on the right side and a right edge of the display screen 10 in the X direction may be greater than or equal to L/4, and further, a vertical distance between an upper edge of the two first adhesives 1011 and an upper edge of the display screen 10 in the Y direction may be greater than or equal to H/4, and a vertical distance between a lower edge of the two first adhesives 1011 and a lower edge of the display screen 10 in the Y direction may be greater than or equal to H/4.

In this example, the shape and/or size of each first adhesive 1011 in the first adhesive layer 101 may be completely different or the shape and size of a portion of the first adhesive 1011 in the first adhesive layer 101 may be completely the same. As an example, referring to the structural schematic diagram of the display screen described with reference to fig. 6, the first adhesive layer 101 includes one rectangular first adhesive member 1011 disposed on the left side and three square first adhesive members 1011 disposed on the right side and arranged in a vertical direction based on a predetermined interval, wherein a horizontal distance between the left edge of the rectangular first adhesive member 1011 and the left edge of the display screen 10 in the X direction may be greater than or equal to L/4, a horizontal distance between the right edge of each square first adhesive member 1011 and the right edge of the display screen in the X direction may be greater than or equal to L/4, and further, a vertical distance between the upper edge of the rectangular first adhesive member 1011 disposed on the uppermost side and the upper edge of the display screen 10 may be greater than or equal to H/4, and a vertical distance between the lower edge of the rectangular first adhesive member 1011 disposed on the lowermost side and the lower edge of the display screen 10 may be greater than or equal to H/4.

In this embodiment, the first adhesive member 1011 of the first adhesive layer 101 may be a buffer material having an adhesive disposed on a side facing the middle frame 20 and a side facing the display screen 10, so as to fix the display screen 10 on the middle frame 20, such as foam, silica gel, foam, and the like. The first adhesive layer 101 not only can support the display screen 10 to form a first gap 104 between the edge area of the display screen 10 and the middle frame 20, but also can absorb part of impact energy after the display screen 10 is impacted, so that the deformation of the display screen 10 after being impacted is reduced, and the anti-falling performance of the display screen 10 is improved.

Alternatively, the impact energy absorption rate of the first bonding member 1011 may be more than 2%.

Further, a buffer layer 103 is further disposed on the periphery of the first adhesive layer 101, that is, the buffer layer 103 is disposed in the first gap 104 between the display screen 10 and the middle frame 20, and the impact energy absorption rate of the buffer layer 103 is greater than that of the first adhesive layer 101.

It should be noted that, when the general terminal device falls, the edge area of the display screen 10 is grounded first, after the first adhesive layer 101 is disposed in the central area of the display screen 10, a first gap 104 is formed between the edge area of the display screen 10 and the middle frame 20, and the edge area of the display screen 10 may have sufficient buffer space to vibrate, but there is no buffer space between the central area of the display screen 10 and the middle frame 20, so that the cracking point on the display screen 10 may be concentrated in the central area of the display screen 10, and the buffer layer 103 is disposed on the periphery of the first adhesive layer 101, and the buffer layer 103 and the first adhesive layer 101 may sequentially absorb the impact energy of the display screen 10, so as to reduce the vibration amplitude and deformation amount of the whole display screen 10 after being impacted, and improve the cracking height of the display screen 10, thereby improving the falling resistance of the display screen 10.

In an example, referring to the schematic structural diagram of the display screen shown in fig. 7, the buffer layer 103 may be disposed at the periphery of the first adhesive layer 101 without a gap between the periphery of the buffer layer 103 and the edge of the display screen 10, in which case, the inner contour of the buffer layer 103 is identical to the shape of the outer contour of the first adhesive layer 101, and, as shown in fig. 7, if the outer contour of the first adhesive layer 101 is rectangular, the buffer layer 103 may be disposed at the periphery of the first adhesive layer 101 without a gap, and the inner contour of the buffer layer 103 is also rectangular, and the outer contour of the buffer layer 103 is identical to the shape of the display screen 10, and no gap exists between the periphery of the buffer layer 103 and the edge of the display screen 10, so that the buffer layer 103 and the first adhesive layer 101 cover the entire back surface of the display screen 10.

In another example, referring to a sixth structural diagram of the display screen shown in fig. 8 and a second sectional diagram of the terminal device shown in fig. 9 along the thickness direction of the display screen, the buffer layer 103 may be disposed adjacent to the periphery of the first adhesive layer 101 at a certain interval. Optionally, the buffer layer 103 is spaced from the first adhesive layer 101 and from the edge of the display screen 10, or the buffer layer 103 is spaced from the first adhesive layer 101 but is not spaced from the edge of the display screen 10.

In other examples, buffer layer 103 may also include a plurality of second buffers. For example, the buffer layer 103 may include two second buffers, which may be disposed at left and right sides of the first adhesive layer 101 at intervals.

Alternatively, the thickness of the buffer layer 103 may be the same as that of the first adhesive layer 101. If the buffer layer 103 includes a plurality of second buffers, the thickness of each second buffer is the same.

By way of example and not limitation, the material of the buffer layer 103 may be a buffer material such as foam, silica gel, foam, or the like. The impact energy absorption rate of the buffer layer 103 may be greater than 5%.

In the embodiment of the present application, as shown in fig. 1, an edge area of a side surface of the middle frame 20 facing the display screen 10 may be glued with an edge of the display screen 10 to further fix the display screen 10 to the middle frame 20.

In one example, if the display screen 10 is a straight screen, the adhesive 102 may be dispensed on the edge area of the middle frame 20 based on a dispensing process, and then the display screen 10 is pressed on the middle frame 20 to glue the display screen 10 with the middle frame 20 through the adhesive 102. If the display screen 10 is a curved screen, the display screen 10 includes a planar portion and an arc portion extending outward along an edge of the planar portion, and the adhesive 102 may be dispensed on an edge area of the middle frame 20 based on a dispensing process, so that the edge of the arc portion of the display screen 10 is pressed against the middle frame 20 to glue the display screen 10 and the middle frame 20 through the adhesive 102.

Illustratively, the adhesive 102 may be a waterproof adhesive.

The side of the middle frame 20 facing away from the display screen 10 is provided with a battery compartment 202 for accommodating the battery 30, and the side of the middle frame 20 facing away from the display screen 10 is provided with a second adhesive layer 201 to fix the battery 30 in the battery compartment 202 through the second adhesive layer 201.

Further, referring to another cross-sectional view of the terminal device along the thickness direction of the display screen shown in fig. 11, in order to increase the buffer space of the central area of the display screen 10 along the thickness direction H when the central area of the display screen 10 is impacted, the setting position of the second adhesive layer 201 in the middle frame 20 may avoid the setting position of the first adhesive layer 101 in the middle frame 20, specifically, along the thickness direction H of the display screen 10, the projection of the second adhesive layer 201 on the middle frame 20 and the projection of the first adhesive layer 101 on the middle frame 20 do not overlap, so that a second gap 203 is formed between the projection area of the first adhesive layer 101 on the middle frame 20 and the battery 30, thereby increasing the buffer space of the central area of the display screen 10 along the thickness direction H of the display screen 10, avoiding the central area of the display screen 10 from being broken by direct impact of the middle frame 20 and the battery 30 after the display screen 10 is impacted, and improving the anti-drop performance of the display screen 10.

In an example, referring to the cross-sectional view shown in fig. 11 and the first schematic structural view of the middle frame shown in fig. 12, a groove 2011 may be formed in the second adhesive layer 201, where the groove 2011 is disposed at a projection area of the first adhesive layer 101 on the middle frame 20 along the thickness direction H of the display screen 10, and the size of the groove 2011 may be greater than or equal to the size of the first adhesive layer 101, so that a second gap 203 is formed between the projection area of the first adhesive layer 101 on the middle frame 20 and the battery 30, and a projection of the second adhesive layer 201 on the middle frame 20 and a projection of the first adhesive layer 101 on the middle frame 20 along the thickness direction H of the display screen 10 do not overlap.

Further, the shape of the recess 2011 may be the same as that of the first adhesive layer 101, and if the first adhesive layer 101 includes a square first adhesive member 1011 as shown in fig. 4, the shape of the recess 2011 may also be square.

In another example, referring to the second schematic structural diagram of the middle frame shown in fig. 13, the second adhesive layer 201 may include a plurality of second adhesive pieces 2012 having the same shape or different shapes, and the plurality of second adhesive pieces 2012 may be disposed at positions on the middle frame 20 so as to avoid the projection area of the first adhesive layer 101 on the middle frame 20 along the thickness direction H of the display screen 10, so that the projection area of the first adhesive layer 101 on the middle frame 20 forms the second gap 203 with the battery 30.

The foregoing is merely specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes and substitutions are intended to be covered by the scope of the present application.
