Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

In order to solve the technical problem of poor falling strength of a display screen module of an electronic device in the prior art, an embodiment of the invention provides a display screen body assembly. This display screen body subassembly includes: display screen body, first circuit board and second circuit board. The first circuit board and the second circuit board are respectively electrically connected with the display screen body, and the first circuit board and the second circuit board are arranged in an overlapped mode. The first circuit board is provided with a first space at the part overlapped with the second circuit board, the second circuit board is provided with a first element protruding from the area corresponding to the first space, and the first element is embedded into the first space so as to reduce the stacking thickness of the first circuit board and the second circuit board. As described in detail below.

Referring to fig. 1, fig. 2a-2b and fig. 3a-3c, fig. 1 is a schematic structural diagram of a display panel assembly according to an embodiment of the present invention, fig. 2a-2b are schematic structural diagrams of a first circuit board and a second circuit board according to an embodiment of the present invention, and fig. 3a-3c are schematic structural diagrams of a first device according to an embodiment of the present invention, in which a first space in the form of a through hole is adapted to different thicknesses.

In which fig. 2a shows a first circuit board 12, fig. 2b shows a second circuit board 13, and fig. 3a-3c show a first embodiment of the cross-sectional structure of the first circuit board 12 and the second circuit board 13 shown in fig. 1 in the H-H direction.

In one embodiment, the display screen body assembly 10 may be applied to a display device, such as a smart phone, a tablet computer, etc., which serves as a display device to provide a human-computer interaction window to a user. Specifically, the display panel assembly 10 may apply an OLED (organic light-Emitting semiconductor) display technology.

Specifically, the display screen body assembly 10 includes a display screen body 11, a first circuit board 12, and a second circuit board 13. The display screen body 11 may be substantially an OLED display panel. The first circuit board 12 and the second circuit board 13 are electrically connected to the display screen body 11, respectively, and are used for implementing corresponding functions of the display screen body 11, such as a display function of the display screen body 11 and a touch function of the display screen body 11.

Also, the first circuit board 12 and the second circuit board 13 are disposed to overlap. The first circuit board 12 has a first space 121 formed at a portion overlapping with the second circuit board 13, as shown in fig. 2 a. The second circuit board 13 is provided with a first element 131 protruding from an area corresponding to the first space 121, i.e. the first element 131 protrudes from the surface of the second circuit board 13, as shown in fig. 3a-3 c. Compared with the case that the first element 131 on the second circuit board 13 is directly stacked on the first circuit board 12, the first element 131 is embedded in the first space 121, so that the stacking thickness of the first circuit board 12 and the second circuit board 13 can be reduced, that is, the overall thickness of the assembly formed by stacking the first circuit board 12 and the second circuit board 13 can be reduced.

The stacking thickness of the first circuit board 12 and the second circuit board 13 should be understood as the dimension of the whole assembly formed by stacking the first circuit board 12 and the second circuit board 13 in the opposite direction (as shown by the arrow X in fig. 3a, the same below) of the first circuit board 12 and the second circuit board 13, and fig. 3a shows the stacking thickness W of the first circuit board 12 and the second circuit board 13.

In this way, the reduction of the stacking thickness of the first circuit board 12 and the second circuit board 13 means that the distance between the first circuit board 12 and the second circuit board 13 and the housing of the display device is increased, so that the risk of the interference problem such as collision between the first circuit board 12 and the housing of the display device and the second circuit board 13 is reduced, and therefore, the risk of the interference problem between the display screen body assembly 10 and the housing of the display device can be reduced, and the falling strength of the display screen body assembly 10 can be improved.

In one embodiment, the first circuit board 12 is preferably a driving circuit board, on which circuits, devices, etc. for driving the display screen body 11 to display can be integrated. And the second circuit board 13 is preferably a touch circuit board on which circuits, devices, etc. for implementing the touch function of the display screen body 11 may be integrated. In addition, in order to reinforce the circuit board structure, a reinforcing member is usually added on the circuit board in consideration of the large size of the touch chip. Therefore, the second circuit board 13 of the present embodiment is provided with a touch device for realizing the touch function of the display screen body 11 and a reinforcing member for reinforcing the circuit board structure.

In particular, the surface of the second circuit board 13 facing away from the first element 131 is provided with a second element 132, also protruding, as shown in fig. 3 a. The first element 131 is one of a touch device and a reinforcement member, and the second element 132 is the other of the touch device and the reinforcement member. The following description will be made by taking the first element 131 as an example embedded in the first space 121 on the first circuit board 12 and the first element 131 as a reinforcing member, which is only for discussion purpose and is not limited thereto.

In one embodiment, the thickness of the first circuit board 12 is preferably 0.1mm to 0.3mm, such as 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, etc., which is beneficial for the functional implementation and module design of the circuit on the first circuit board 12. The thickness of the first element 131 is preferably 0.1mm-0.25mm, e.g. 0.1mm, 0.15mm, 0.2mm, 0.25mm, etc. The thickness of the first element 131 is to be understood as the dimension of the first element 131 in a direction perpendicular to the surface of the second circuit board 13 where it is located. That is, there are cases where the thickness of the first element 131 is greater than, equal to, and less than the thickness of the first circuit board 12.

Please continue with fig. 3a-3 c. In one embodiment, the first space 121 formed on the first circuit board 12 is preferably a through hole for facilitating the process, because the process of forming a through hole directly on the first circuit board 12 is easy to implement. At this time, the thickness of the first element 131 may be greater than the thickness of the first circuit board 12, as shown in fig. 3b, the stacking thickness of the first circuit board 12 and the second circuit board 13 may be reduced by one thickness of the first circuit board 12; the thickness of the first component 131 can also be equal to the thickness of the first circuit board 12, as shown in fig. 3a, the stacking thickness of the first circuit board 12 and the second circuit board 13 can be reduced by the thickness of one first circuit board 12 or the thickness of one first component 131 (both are equal); alternatively, the thickness of the first element 131 is smaller than that of the first circuit board 12, as shown in fig. 3c, the stacking thickness of the first circuit board 12 and the second circuit board 13 can be reduced by one thickness of the first element 131.

Referring to fig. 4a-4c, fig. 4a-4c are schematic structural views of a first element with a blind via type first space adapted to different thicknesses according to an embodiment of the present invention. Fig. 4a to 4c show a second embodiment of the cross-sectional structure of the first circuit board 12 and the second circuit board 13 shown in fig. 1 in the H-H direction.

In an alternative embodiment, the depth of the first space 121 is smaller than the thickness of the first circuit board 12, i.e. the first space 121 is a blind hole. At this time, the thickness of the first element 131 may be greater than the depth of the first space 121, as shown in fig. 4a, the stacking thickness of the first circuit board 12 and the second circuit board 13 may be reduced by one depth of the first space 121; or the thickness of the first element 131 may be smaller than the depth of the first space 121, as shown in fig. 4b, the stacking thickness of the first circuit board 12 and the second circuit board 13 may be reduced by the thickness of one first element 131.

Preferably, the thickness of the first element 131 is equal to the depth of the first space 121, as shown in fig. 4c, the stacking thickness of the first circuit board 12 and the second circuit board 13 can be reduced by the depth of one first space 121 or the thickness of one first element 131 (both are equal). In this way, the design that the first space 121 is a blind hole and the thickness of the first element 131 is equal to the depth of the first space 121 can ensure the rationalization of the design of the stacked module of the first circuit board 12 and the second circuit board 13, and at the same time, the stacked thickness of the first circuit board 12 and the second circuit board 13 can be reduced to the maximum.

Referring to fig. 1, fig. 5a to 5c and fig. 6a to 6c, fig. 5a to 5c are schematic structural diagrams of a first element with different thicknesses adapted to a second space in the form of a through hole according to an embodiment of the present invention, and fig. 6a to 6c are schematic structural diagrams of a first element with different thicknesses adapted to a second space in the form of a blind hole according to an embodiment of the present invention. Fig. 5a to 5c show a third embodiment of the sectional structure of the first circuit board 12 and the second circuit board 13 shown in fig. 1 in the H-H direction, and fig. 6a to 6c show a fourth embodiment of the sectional structure of the first circuit board 12 and the second circuit board 13 shown in fig. 1 in the H-H direction.

In one embodiment, the display panel assembly 10 may employ flexible display technology, which generally requires the first circuit board 12 and the second circuit board 13 electrically connected to the display panel 11 to be bent to one side of the display panel 11. Therefore, the display screen assembly 10 further includes a connector 14, and the connector 14 is disposed on a side of the first circuit board 12 away from the second circuit board 13, so as to fix the first circuit board 12 and the second circuit board 13 relative to the display screen body 11 after the connector 14 is connected to the display screen body 11. Specifically, the connecting body 14 may be a double-sided tape, and the like, and connects the display panel body 11 with the bending motion of the first circuit board 12 and the second circuit board 13, so that the first circuit board 12 and the second circuit board 13 are fixed relative to the display panel body 11.

Specifically, for the case that the thickness of the first element 131 is greater than the thickness of the first circuit board 12 and the first space 121 is a through hole in the above embodiment, in order to further reduce the stacking thickness of the first circuit board 12 and the second circuit board 13, the area of the connecting body 14 corresponding to the first space 121 of the embodiment is opened with the second space 141 communicating with the first space 121, and the first element 131 is embedded in the first space 121 and the second space 141.

Please continue to refer to fig. 5a-5 c. In an embodiment, also for the convenience of the process, the second space 141 formed on the connecting body 14 is preferably a through hole. At this time, the thickness of the first element 131 may be greater than the thickness of the first circuit board 12 and less than the sum of the thicknesses of the first circuit board 12 and the connecting body 14, as shown in fig. 5b, the stacking thickness of the first circuit board 12 and the second circuit board 13 may be reduced by the thickness of one first element 131; the thickness of the first component 131 can also be equal to the sum of the thicknesses of the first circuit board 12 and the connecting body 14, as shown in fig. 5a, the stacking thickness of the first circuit board 12 and the second circuit board 13 can be reduced by the thickness of one first component 131 or the sum of the thicknesses of one first circuit board 12 and the connecting body 14 (both are equal); alternatively, the thickness of the first component 131 is larger than the sum of the thicknesses of the first circuit board 12 and the connecting body 14, as shown in fig. 5c, the stacking thickness of the first circuit board 12 and the second circuit board 13 can be reduced by one sum of the thicknesses of the first circuit board 12 and the connecting body 14.

Please continue to refer to fig. 6a-6 c. In an alternative embodiment, the depth of the second space 141 is smaller than the thickness of the connector 14, i.e. the second space 141 is a blind hole. Therefore, in order to further reduce the stacking thickness of the first circuit board 12 and the second circuit board 13, the connecting body 14 retained at the bottom of the second space 141 allows the first element 131 embedded in the second space 141 to be connected with the connecting body 14 at the bottom of the second space 141, so that the connecting body 14 can also directly fix the second circuit board 13 through the first element 131, thereby avoiding the problem that the second circuit board 13 interferes with the chassis due to the separation of the first circuit board 12 and the second circuit board 13.

That is, the thickness of the first element 131 is greater than or equal to the sum of the depths of the first space 121 and the second space 141, as shown in fig. 6a and 6c, so that the first element 131 can be connected to the connection body 14 at the bottom of the second space 141 after the first element 131 is inserted into the first space 121 and the second space 141. Preferably, the thickness of the first element 131 is equal to the sum of the depths of the first space 121 and the second space 141, so that the stacking thickness of the first circuit board 12 and the second circuit board 13 can be minimized while the first element 131 can be connected to the connecting body 14 at the bottom of the second space 141.

Of course, the thickness of the first element 131 is greater than the depth of the first space 121 and may also be smaller than the sum of the depths of the first space 121 and the second space 141, as shown in fig. 6b, after the first element 131 is inserted into the first space 121 and the second space 141, a certain gap is formed between the first element 131 and the bottom of the second space 141, which is not limited herein.

Of course, in other embodiments of the present invention, the connecting body 14 may not be provided with the second space 141, and the first element 131 passes through the first space 121 and directly abuts against the connecting body 14, as shown in fig. 3a, the connecting body 14 can also directly fix the second circuit board 13 through the first element 131, so as to avoid the problem that the second circuit board 13 interferes with the housing due to the separation of the first circuit board 12 and the second circuit board 13.

Optionally, the thickness of the connecting body 14 is preferably 0.03mm to 0.2mm, such as 0.03mm, 0.05mm, 0.1mm, 0.15mm, 0.2mm, and the like, so as to facilitate the connecting body 14 to relatively fix the first circuit board 12, the second circuit board 13, and the display screen body 11, which is not limited herein.

Please continue to refer to fig. 5 a. In an embodiment, an orthographic projection of the first element 131 on the second circuit board 13 on the reference plane is located in an orthographic projection of the first space 121 on the reference plane, so that the first element 131 on the second circuit board 13 can be embedded in the first space 121 on the first circuit board 12. Wherein the reference plane is perpendicular to the relative direction of the first circuit board 12 and the second circuit board 13. The reference plane is shown as plane a in fig. 5a, and the relative direction of the first circuit board 12 and the second circuit board 13 is shown as arrow X in fig. 5 a.

Further, the distance between each side of the orthographic projection of the first element 131 on the reference plane and the corresponding side of the orthographic projection of the first space 121 on the reference plane is not less than 0.25mm, which further ensures that the first element 131 can be embedded in the first space 121 on the first circuit board 12.

Fig. 5a and 7 illustrate the case where the orthographic projection B of the first element 131 on the reference plane a is rectangular and the orthographic projection C of the first space 121 on the reference plane a is rectangular. And D is the distance between each side of the orthographic projection B and the corresponding side of the orthographic projection C, wherein the distance D is not less than 0.25 mm.

Also, fig. 5a shows a case where orthographic projections of the first space 121 and the second space 141 on the reference plane a coincide. Of course, in other embodiments of the present invention, the orthographic projection of the first space 121 on the reference plane may also be in the orthographic projection of the second space 141 on the reference plane, or the orthographic projection of the second space 141 on the reference plane is in the orthographic projection of the first space 121 on the reference plane, which is not limited herein.

Continuing to refer to fig. 1, fig. 1 shows the insulating protective film 15. In fig. 3a to 3c, 4a to 4c, 5a to 5c, and 6a to 6c, the insulating protective film 15 is omitted.

In one embodiment, the display screen body assembly 10 further includes an insulating protective film 15, the insulating protective film 15 covers at least a portion of a surface of the second circuit board 13 facing away from the first circuit board 12, and the insulating protective film 15 further extends onto a surface of the first circuit board 12 close to the second circuit board 13. That is to say, the first circuit board 12 and the second circuit board 13 are combined together through the insulating protection film 15, so that the risk of separation of the first circuit board 12 and the second circuit board 13 can be reduced, the risk of interference problems such as collision between the first circuit board 12 and the chassis and the second circuit board 13 is further reduced, specifically, the risk of interference problems such as collision between the second circuit board 13 and the chassis is reduced, and the falling strength of the display screen body assembly 10 can be improved.

It should be noted that, the insulating protection film 15 of the present embodiment, in combination with the connecting body of the above embodiments, can further reduce the risk of separating the first circuit board 12 from the second circuit board 13 by connecting the first element to connect the second circuit board, and after the connecting body is connected to the display screen body 11 along with the bending of the first circuit board 12 and the second circuit board 13, it is ensured that the first circuit board 12 and the second circuit board 13 are reliably fixed to the display screen body 11.

In addition, in the above embodiment, the first element is taken as an example of the reinforcement member, which means that the second element 132 on the surface of the second circuit board 13 away from the first element is a touch device. After the insulating protection film 15 is attached, the second member 132 directly contacts the insulating protection film 15, and the insulating protection film 15 also directly contacts the circuit on the first circuit board 12. Therefore, the insulating protection film 15 of the present embodiment has an insulating property to prevent the second element 132 on the second circuit board 13 from being electrically connected to the circuit on the first circuit board 12 to affect the normal function.

Alternatively, the thickness of the insulating protective film 15 is preferably 0.03mm to 0.1mm, for example, 0.03mm, 0.05mm, 0.1mm, and the like, so that the insulating protective film 15 can reliably bond the first circuit board 12 and the second circuit board 13 together. Here, the thickness of the insulating protective film 15 should be understood as the dimension of the insulating protective film 15 in the direction in which the first circuit board 12 opposes the second circuit board 13.

In summary, in the display panel assembly provided by the present invention, the portion of the first circuit board overlapping the second circuit board is provided with a first space, and the protruding first element on the second circuit board is embedded into the first space, so as to reduce the stacking thickness of the first circuit board and the second circuit board. The reduction of the stacking thickness of the first circuit board and the second circuit board means that the distance between the first circuit board and the housing of the display device and the distance between the second circuit board and the housing of the display device are increased, so that the risk of interference problems such as collision between the first circuit board and the housing of the display device and the risk of interference problems between the display screen body assembly and the housing of the display device are reduced, and the falling strength of the display screen body assembly can be improved.

In addition, in the present invention, unless otherwise expressly specified or limited, the terms "connected," "stacked," and the like are to be construed broadly, e.g., as meaning permanently connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
