Detailed Description
To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
The display module is an important component of the display screen and mainly comprises a display panel and a back plate, and the display panel is attached to the back plate.
In the manufacturing process of the display screen, the display module is required to be placed on the equipment table, and one surface of the backboard far away from the display panel is contacted with the equipment table. In order to avoid abrasion of the back plate, a protective film is generally attached to the side of the back plate away from the display panel, and the back plate is in contact with the equipment table through the protective film.
However, in the manufacturing process, the display module often generates static electricity, and the static electricity will affect the electrical property of the display panel, resulting in poor display effect of the display module. In order to solve the problem, in the related art, a layer of anti-static liquid is coated on the device platform, so that a conductive layer is formed on the device platform, and static electricity on the display module can be conducted to the device platform through the conductive layer. However, since the conductive capability of the protective film itself is poor, even if a conductive layer is provided on the device stage, the effect of eliminating static electricity is not good.
In order to solve the above technical problems, an embodiment of the present disclosure provides a display module, which may be an OLED (Organic Light-Emitting Diode) display module.
Fig. 1 is a schematic view of the display module, which includes a display panel 100, a backplane 200 and a protection film 400. The display panel 100, the backplane 200, and the protective film 400 are sequentially stacked, one surface of the protective film 400 is electrically connected to the backplane 200, and the other surface of the protective film 400 is used for electrical connection to the device stage 300.
In this embodiment, the protection film 400 can protect the backplate 200 and prevent the backplate 200 from being worn. Because one side of the protection film 400 is electrically connected with the backplate 200, and the other side of the protection film 400 is electrically connected with the equipment platform 300, the protection film 400 can dredge static electricity from the backplate 200 to the equipment platform 300, thereby eliminating the static electricity and avoiding the static electricity from influencing the display module.
As can be seen from the foregoing, the protection film 400 plays a key role in preventing static electricity from affecting the display module, and the protection film 400 is described below.
The disclosed embodiment provides a protection film, fig. 2 is a schematic structural diagram of a first viewing angle of the protection film, the first viewing angle of the protection film refers to a viewing angle facing a first surface of a film body 1, and in the embodiment, the protection film includes the film body 1 and a conductive body 2, in combination with fig. 2. The electrical conductor 2 is connected to the membrane body 1, a first part of the electrical conductor 2 being located on a first side of the membrane body 1 and a second part of the electrical conductor 2 being located on a second side of the membrane body 1.
With reference to fig. 1, after the protective film 400 provided by the embodiment of the disclosure is attached to the backplate 200 of the display module, the film body 1 can protect the backplate 200 and prevent the backplate 200 from being worn. Because the first part of the conductor 2 is located on the first surface of the film body 1 and can be in contact with the back plate 200, and the second part of the conductor 2 is located on the second surface of the film body 1 and can be in contact with the equipment platform 300, the conductor 2 can dredge static electricity from the back plate 200 to the equipment platform 300, thereby eliminating the static electricity and avoiding the static electricity from influencing the display module.
If static electricity occurs on the display panel 100 of the display module, the static electricity is dissipated to the equipment platform 300 through the backplate 200, the first portion of the conductor 2 and the second portion of the conductor 2 in sequence to eliminate the static electricity. If the back plate 200 of the display module has static electricity, the static electricity is dissipated to the equipment platform 300 through the first portion of the conductor 2 and the second portion of the conductor 2 in sequence.
As described above, the protection film 400 is capable of satisfactorily conducting static electricity because the protection film 400 includes the conductor 2. The electrical conductor 2 will now be described.
Referring again to fig. 2, in the present embodiment, the conductive body 2 includes a first conductive layer 21, a second conductive layer 22, and a conductive connecting member 23. The first conducting layer 21 is attached to the first surface of the film body 1, the second conducting layer 22 is attached to the second surface of the film body 1, and the conducting connecting piece 23 is connected to the side edge of the film body 1 and is respectively connected to the first conducting layer 21 and the second conducting layer 22.
In the above implementation manner, the first conductive layer 21 is located on the first surface of the film body 1 and is used for being electrically connected to the back plate 200 of the display module, the second conductive layer 22 is located on the second surface of the film body 1 and is used for being connected to the equipment platform 300, and the conductive connecting member 23 is used for connecting the first conductive layer 21 to the second conductive layer 22, so that the electrical connection between the display module and the equipment platform 300 can be realized through the conductive body 2, and a path is provided for dredging the display module.
The first conductive layer 21, the second conductive layer 22 and the conductive connecting member 23 will be described below, respectively.
In the present embodiment, the first conductive layer 21 has two structural forms, which are as follows:
in a first structure, referring to fig. 2, in the present embodiment, the first conductive layer 21 is a mesh structure, and an outer edge of the first conductive layer 21 is flush with an outer edge of the first surface of the film body 1.
Since the first conductive layer 21 is a mesh structure, the first conductive layer 21 only shields a portion of the first surface of the film body 1. In this way, when the protective film is bonded to the back plate 200 or the device stage 300, the first conductive layer 21 does not excessively affect the adhesion of the film body 1. Since the outer edge of the first conductive layer 21 is flush with the outer edge of the first surface of the film body 1, connection with the conductive connecting member 23 can be facilitated, and connection stability between the first conductive layer 21 and the conductive connecting member 23 is ensured.
It should be noted that although the first conductive layer 21 shown in fig. 2 is an orthogonal mesh structure, in other embodiments, an oblique mesh structure can be selected according to requirements, and the disclosure is not limited thereto.
In a second structure form, referring to fig. 3, fig. 3 is another structure schematic diagram of a first view angle of the protective film, in this embodiment, the first conductive layer 21 includes a plurality of first conductive strips 211, the plurality of first conductive strips 211 are spaced from each other, the plurality of first conductive strips 211 extend along a length direction of the film body 1, and end edges of the plurality of first conductive strips 211 are flush with an outer edge of the first surface of the film body 1.
Based on the same reason of the mesh-shaped first conductive layer 21, since there is a gap between two adjacent first conductive strips 211, the first conductive layer 21 only shields a portion of the first surface of the film body 1. In this way, when the protective film is bonded to the back plate 200 or the device stage 300, the first conductive layer 21 does not excessively affect the adhesion of the film body 1. Since the end edges of the first conductive strips 211 are flush with the outer edge of the first face of the film body 1, the connection with the conductive connecting piece 23 is facilitated, and the connection stability between the first conductive layer 21 and the conductive connecting piece 23 is ensured.
In order to ensure that the first conductive layer 21 can be in sufficient contact with the back plate 200 or the device table 300 to ensure the conductive performance, optionally, the orthographic projections of the first conductive layer 21 on the plane where the first surface of the film body 1 is located are all located in the first surface of the film body 1. With such a design, the first conductive layer 21 can be prevented from protruding beyond the first surface of the film body 1 and affecting other components.
Illustratively, the first conductive layer 21 is any one of conductive glass or conductive metal. For example, the structure is an Indium Tin Oxide (ITO) structure, so that the function of electrostatic dissipation is achieved by utilizing the electrical conduction characteristic thereof.
Illustratively, the first conductive layer 21 is uniformly distributed on the first surface of the film body 1 by means of sputtering or coating.
In the present embodiment, the second conductive layer 22 also has two structural forms, which are as follows:
in the first structure form, referring to fig. 4, fig. 4 is a schematic structural diagram of a second viewing angle of the protective film, which refers to a viewing angle toward the second side of the film body 1.
In the present embodiment, the second conductive layer 22 is a mesh structure, and the outer edge of the second conductive layer 22 is flush with the outer edge of the second surface of the film body 1.
Since the second conductive layer 22 is a mesh structure, the second conductive layer 22 only shields a portion of the second surface of the film body 1. In this way, when the protective film is bonded to the back plate 200 or the device stage 300, the second conductive layer 22 does not affect the adhesion of the film body 1 too much. Since the outer edge of the second conductive layer 22 is flush with the outer edge of the second face of the film body 1, connection with the conductive connecting member 23 can be facilitated, and connection stability between the second conductive layer 22 and the conductive connecting member 23 is ensured.
It should be noted that although the second conductive layer 22 shown in fig. 4 is an orthogonal mesh structure, in other embodiments, an oblique mesh structure can be selected according to the requirement, which is not limited by the present disclosure.
In a second structure form, referring to fig. 5, fig. 5 is another structure schematic diagram of a second view angle of the protective film, in this embodiment, the second conductive layer 22 includes a plurality of second conductive strips 221, the plurality of second conductive strips 221 are spaced from each other, the plurality of second conductive strips 221 all extend along the length direction of the film body 1, and end edges of the plurality of second conductive strips 221 are all flush with an outer edge of the second surface of the film body 1.
Based on the same reason of the mesh-shaped second conductive layer 22, since there is a gap between two adjacent second conductive strips 221, the second conductive layer 22 only shields a portion of the second surface of the film body 1. In this way, when the protective film is bonded to the back plate 200 or the device stage 300, the second conductive layer 22 does not affect the adhesion of the film body 1 too much. Since the end edges of the second conductive strips 221 are flush with the outer edge of the second face of the film body 1, the connection with the conductive connecting piece 23 can be facilitated, and the connection stability between the second conductive layer 22 and the conductive connecting piece 23 is ensured.
In order to ensure that the second conductive layer 22 can be in sufficient contact with the backplate 200 or the device stage 300 to ensure the conductive performance, optionally, the orthographic projections of the second conductive layer 22 on the plane of the second face of the film body 1 are all located in the second face of the film body 1. By such a design, the second conductive layer 22 can be prevented from exceeding the second surface of the film body 1 and affecting other components.
Illustratively, the second conductive layer 22 is any one of conductive glass or conductive metal. For example, the structure is an Indium Tin Oxide (ITO) structure, so that the function of electrostatic dissipation is achieved by utilizing the electrical conduction characteristic thereof.
Illustratively, the second conductive layer 22 is uniformly distributed on the second side of the film body 1 by means of sputtering or coating.
It should be noted that, both the first conductive layer 21 and the second conductive layer 22 may be mesh structures, or both the first conductive layer 21 and the second conductive layer 22 may be strip structures, or the first conductive layer 21 and the second conductive layer 22 may be mesh structures. The present disclosure is not so limited.
In this embodiment, the conductive connecting member 23 is a conductive adhesive and is located at the peripheral outer edge of the film body 1. For example, if the film body 1 is a rectangular film body 1, the conductive connecting member 23 is located at least on one side of the film body 1 to connect the first conductive layer 21 and the second conductive layer 22. Of course, the conductive connecting members 23 may be located on all sides of the film body 1 to increase the connection area between the first conductive layer 21 and the second conductive layer 22.
The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
