Fig. 1 is a schematic structural diagram of a display device 100 according to an embodiment of the present application. For convenience of explanation, the display device 100 or the display module 10 defines a display side X for displaying and a rear side Y opposite to the display side X.
As shown in fig. 1, the display device 100 includes a display module 10 and a flexible circuit board 50, wherein the display module 10 is used for displaying, and may include a display panel 20 on a display side and a conductive back plate 31 on a back side Y. The flexible circuit board 50 is used to electrically connect the display module 10 with an external circuit. The external circuit may be, for example, a processing circuit of a touch signal, or may be other circuits of the client system, and similar to the case that the external circuit is other kinds of circuits, the details are not repeated here.
The display panel 20 may be an Organic Light-Emitting Diode (OLED) display panel, a liquid crystal display (Liquid Crystal Display, LCD) panel, a Micro Light-Emitting Diode (Mini LED) display panel, or a Micro Light-Emitting Diode (Micro LED) display panel.
In this embodiment, in the case where the display device 100 is a touch-type liquid crystal display device, the display module 10 may further include a touch layer 40 and a backlight module 30.
The touch layer 40 is located on the display side X of the display panel 20. And the touch layer 40 is used for sensing a touch operation, the flexible circuit board 50 is used for electrically connecting the touch layer 40 with an external circuit, such as a processing circuit of a touch signal.
The backlight module 30 is located at the back side Y of the display panel 20. And the backlight module 30 is used for providing a backlight source for the display panel 20, the backlight module 30 may include a metal back plate, and the metal back plate forms the conductive back plate 31.
In the embodiment of the present application, as described above, the display module 10 includes the conductive back plate 31, and the flexible circuit board 50 has the main body 51;
wherein, the main body 51 is arranged on the conductive backboard 31 and is positioned on the back side Y of the conductive backboard 31; the main body 51 is provided with a conductive pattern 53 for electrically connecting with an external circuit, and the conductive pattern 53 is positioned on one side of the main body 51 facing the conductive backboard 31 and is opposite to the conductive backboard 31;
the display device 100 further includes a spacer 60, and the spacer 60 is sandwiched between the conductive back plate 31 and the main body portion 51 so that a space is provided between the conductive pattern 53 and the conductive back plate 31.
In the above-described aspect, by providing the spacer 60 and clamping the spacer 60 between the conductive back plate 31 and the main body portion 51 with a space between the conductive pattern 53 and the conductive back plate 31, in effect, the spacer 60 plays a supporting role to support the flexible circuit board 50, and a space is formed between the area occupied by the conductive pattern 53 on the flexible circuit board 50 and the conductive back plate 31, thereby preventing static electricity from being generated due to direct contact between them, and thus improving the reliability of the display device 100.
In the embodiment of the present application, the conductive pattern 53 may be a gold finger, and the conductive pattern 53 is disposed toward the conductive back plate 31, and in addition, the conductive pattern 53 is also disposed opposite to the conductive back plate 31 in general.
Illustratively, the main body 51 is disposed opposite to the mounting surface 312 on the side of the thickness direction H of the conductive back plate 31, and the spacer 60 may be disposed on the mounting surface 312 with the projection of the conductive pattern 53 on the mounting surface 312 spaced from the spacer 60. Here, the mounting surface 312 may be a surface of the conductive back plate 31 facing the back side Y.
In other words, as for the positional relationship of the conductive pattern 53 and the spacer 60, the conductive pattern 53 and the spacer 60 are arranged at a distance from each other when the structure diagram shown in fig. 1 is viewed from the top. The spacer 60 does not contact the conductive pattern 53 and does not affect the electrical contact of the conductive pattern 53 with an external circuit. Alternatively, the spacer 60 may be made of a conductive material, for example, it is possible to integrally form the spacer 60 with the conductive back plate 31.
Of course, the embodiment of the present application is not limited thereto, and at least part of the structure of the spacer 60 may be in contact with the conductive pattern 53, and the spacer 60 needs to be made of an insulating material to avoid conducting the conductive pattern to the conductive back plate 31.
In this embodiment, referring to fig. 1, the main body 51 is a portion of the flexible circuit board 50 located on the back side Y of the conductive back plate 31, and the main body 51 may be mechanically connected to the conductive back plate 31. Illustratively, the main body 51 and the conductive back plate 31 may be bonded together by the adhesive 70, that is, the adhesive 70 is bonded between the mounting surface 312 and the main body, or may be connected together by a fastener such as a screw, so long as the main body 51 and the conductive back plate 31 can be connected together, which is not limited in this application.
For convenience of description, the main body 51 defines a first end 511 and a second end 512 that are disposed opposite to each other, and for example, the first end 511 may be located at an edge of the conductive back plate 31, that is, the first end 511 may be located at a position corresponding to the first edge 311 of the mounting surface 312, and the second end 511 may be located at a predetermined position inside the edge of the conductive back plate 31, and the conductive pattern 53 may be disposed on the second end 512.
At this point, glue 70 or a fastener may be located between first end 511 and spacer 60. Thus, the adhesive 70 or the fastener may be clamped between the main body 51 and the conductive back plate 31, and also play a certain role in supporting. Generally, the adhesive 70 is disposed at the same height relative to the mounting surface 312 as the spacer 60 is disposed at the mounting surface 312 or slightly below the spacer 60 is disposed at the mounting surface 312.
Further, the flexible circuit board 50 further includes an extension 52 for electrically connecting with the display module 10. One end of the extension portion 52 is continuous with the first end 511 of the main body portion 51, and the other end of the extension portion 52 protrudes toward one side in the thickness direction of the conductive back plate 31, where continuous means that one end of the extension portion 52 is continuous with the first end 511 of the main body portion 51 as a whole.
Illustratively, the other end of the extension 52 protrudes toward the display side X of the display module 10, such that the interface portion of the extension 52 and the body 51 wraps around the first edge 311. In particular, an electrical connection terminal is actually provided on the extension 52, and the electrical connection terminal is electrically connected to the touch layer 40. In this way, the touch signal sensed by the touch layer 40 is transferred to the flexible circuit board 50 through the electrical connection terminal, so that the electrical connection between the touch layer 40 and the flexible circuit board is realized.
Here, the spacer 60 may be located between the first end 511 and the second end 512 of the body portion 51.
In the above-described aspect, the boundary between the main body portion 51 and the extension portion 52 wraps the edge of the conductive back plate 31, that is, the first edge 311. The spacer 60 is located between the first end 511 and the second end 512 of the body 51, and may support the portion of the body 51 located between the first end 511 and the second end 512 to prevent the second end 512 of the body 51 from sagging into contact with the conductive backplate 31.
In the embodiment of the present application, the spacer 60 may be formed in the vicinity of the conductive pattern 53. For example, on a side of the conductive pattern 53 near the first end 511.
In particular, when the distance h1 between the spacer 60 and the conductive pattern 53 is greater than or equal to 2mm, it can be ensured that the distance between the conductive pattern 53 and the conductive back plate 31 is greater than the safe distance when the spacer 60 supports the main body 51, and the possible conduction situation when the distance between the conductive pattern 53 and the conductive back plate is too close can be effectively avoided.
The distance h1 between the spacer 60 and the conductive pattern 53 refers to the distance between the end of the spacer 60 closest to the conductive pattern 53 and the end of the conductive pattern 53 closest to the spacer 60, that is, the minimum distance between the spacer 60 and the conductive pattern 53.
The specific structure of the spacer 60 is described below with reference to the drawings.
Fig. 2 is a schematic structural diagram of a display device according to an embodiment of the present application under a condition that a flexible circuit board is bent, and fig. 3 is a top view of a spacer in the display device according to an embodiment of the present application.
Referring to fig. 1 and 2, the spacer 60 is configured as a protruding structure protruding from the conductive back plate 31 toward the main body portion 51. This means that the spacer 60 should have a certain thickness in the normal direction of the conductive back plate 31 so as to support the main body 51 away from the mounting surface 312.
Of course, in specific implementation, the protruding height h2 of the spacer 60 from the conductive backboard 31 may be greater than or equal to 2mm, so that when the main body 51 is supported by the spacer 60, the distance between the conductive pattern 53 and the conductive backboard 31 is ensured to be greater than the safe distance, and possible conduction situations when the distance between the conductive pattern and the conductive backboard is too close can be effectively avoided.
It should be noted that the protruding height h2 of the spacer 60 from the conductive back plate 31 refers to the distance between the end of the spacer 60 closest to the main body 51 and the plate surface of the conductive back plate 31.
Of course, it is possible to satisfy both: the distance h1 between the spacer 60 and the conductive pattern 53 is greater than or equal to 2mm, and the protruding height h2 of the spacer 60 from the conductive back plate 31 is greater than or equal to 2mm, so that the supporting effect on the main body portion 51 is better.
In addition, as described above, the spacer 60 and the conductive back plate 31 may be integrally formed, which may improve productivity, and the spacer 60 may be spaced apart from the conductive pattern 53 at a certain distance.
Alternatively, the spacer 60 and the conductive back plate 31 may be formed separately, and the spacer 60 may be detachably connected to the conductive back plate 31. The spacer 60 is attached to the conductive back plate 31 by, for example, adhesive or fasteners, etc.
