A groove 6 communicating with the wire outlet groove 5 is formed on the side surface of the backlight rubber frame 4, and a through groove 7 communicating with the groove 6 is formed on the back surface of the backlight rubber frame 4. The FPC 2 extends into the wire outlet groove 5, the groove 6 and the through groove 7 and exits from the side surface of the backlight rubber frame 4.

[0042] Please refer to Figure 2-7, by making a groove 6 on the side of the backlight rubber frame 4 to facilitate the alignment of the FPC2, since a first rounded corner 8 is provided at the corner of the first long groove 601 and the second long groove 602, and a second rounded corner 9 is provided at the corner of the wire outlet groove 5 and the first long groove 601, and the FPC2 is fixed inside the groove 6 through the back glue 204, it is convenient for the bending and alignment pasting of the FPC2, avoiding the phenomenon of the FPC2 falling off. When installing, the FPC2 of the display screen 1 can be bent out through the groove 6 on the side, and the through groove 7 can be located on the left side, right side, upper side or lower side of the back of the backlight rubber frame 4, so that the FPC2 can be led out from the left and right side surfaces and the upper frame side surface, which can provide multi-directional plugging positions and angles, better meeting the market needs. And because the FPC is in the groove on the side of the backlight rubber frame, the depths of the groove 6 and the through groove 7 are both greater than the thicknesses of the FPC2 and the back glue 204, so that the FPC2 will not protrude from the surface of the backlight rubber frame 4, thus not affecting the assembly of the module.

[0043] Further optimize the FPC side lead-out structure of the display module provided in Embodiment 1. Specifically, as Figure 2-6 shown, the FPC2 includes an extension part 201 horizontally arranged with the backlight rubber frame 4. One end of the extension part 201 is electrically connected to the display screen 1 and forms a bending area 203. The other end of the extension part 201 is fixedly connected with a connecting part 202, and the connector 3 is fixedly connected to the connecting part 202. The groove 6 includes a first long groove 601 opened on the lower surface of the backlight rubber frame 4 and a second long groove 602 opened on the right side of the backlight rubber frame 4. The through groove 7 is located on the right back of the backlight rubber frame 4 and communicates with the second long groove 602. The bending area 203 is located inside the wire outlet groove 5, the extension part 201 is located inside the first long groove 601 and the second long groove 602, and the connecting part 202 is located inside the through groove 7. In this way, the through groove 7 is located on the right side of the back of the backlight rubber frame 4, so that the FPC2 can be led out from the right side surface;

[0044] As Figure 2 and Figure 3 shown, the back of the extension part 201 is fixedly connected with a back glue 204, and the extension part 201 is fixedly connected inside the first long groove 601 and the second long groove 602 through the back glue 204. The FPC2 can be fixed inside the first long groove 601 and the second long groove 602 through the back glue 204, which is convenient for the bending and alignment pasting of the FPC2, making the fixation of the FPC2 more firm and avoiding the phenomenon of the FPC2 falling off;

[0045] As Figure 3 and Figure 7 shown, a first rounded corner 8 is provided at the corner of the first long groove 601 and the second long groove 602, the radius of the first rounded corner 8 is greater than 1 mm, and a second rounded corner 9 is provided at the corner of the wire outlet groove 5 and the first long groove 601, and the radius of the second rounded corner 9 is greater than 1 mm;

[0046] When the FPC is bent around the groove 6 in this way, the angle between the bending area 203 and the extension part 201 is reduced by the first rounded corner 8, and the angle when the extension part 201 is bent is reduced by the second rounded corner 9. Moreover, the four right angles of the backlight rubber frame 4 can be made into rounded corners with a radius of more than 1.0 mm, so as to facilitate the bending of the FPC 2 around the side surface.

[0047] The through groove 7 is located on one of the left side, right side, upper side or lower side of the back of the backlight rubber frame 4. In this way, by opening a plurality of grooves 6 along the side surface of the backlight rubber frame 4, the FPC 2 can be led out from the left and right side surfaces and the upper frame side surface, so as to provide multi-directional plug-in positions and angles.

[0048] Further optimize the FPC side outlet structure of the display module provided in Embodiment 1 or 2, such as Figure 2 and Figure 3 As shown, the extension part 201, the connecting part 202 and the bending area 203 are an integrally formed structure. The bending area 203 and the extension part 201 are in a vertical structure, and the extension part 201 and the connecting part 202 are in a vertical structure. In this way, the FPC 2 is convenient to process, is perpendicular to the backlight rubber frame 4 after bending, and is convenient for wire outlet;

[0049] The depths of the first long groove 601, the second long groove 602 and the through groove 7 are all greater than the thicknesses of the FPC 2 and the back adhesive 204. With such a setting, since the FPC is in the groove on the side surface of the backlight rubber frame, and the depths of the groove 6 and the through groove 7 are both greater than the thicknesses of the FPC 2 and the back adhesive 204, the FPC 2 will not protrude from the surface of the backlight rubber frame 4, so as not to affect the assembly of the module.

[0050] Further optimize the FPC side outlet structure of the display module provided in the above embodiments, such as Figure 8-10 As shown, two positioning grooves 205 are opened on both the front and rear sides of the extension part 201. The inner walls on both the front and rear sides of the first long groove 601 are fixedly connected with first positioning posts 10, and the inner walls on both the front and rear sides of the second long groove 602 are fixedly connected with second positioning posts 11. The first positioning posts 10 and the second positioning posts 11 are respectively located inside the two positioning grooves 205. The back adhesive 204 is a double-sided adhesive, and an avoidance groove 206 is opened at the bending part of the back adhesive 204.

[0051] With such a structural design, when the extension part 201 is bent in the first long groove 601 and the second long groove 602, the two positioning grooves 205 cooperate with the first positioning posts 10 and the second positioning posts 11 to make the FPC 2 fixed in the groove 6 more accurately. At the same time, the existence of the avoidance groove 206 will not cause excessive pressure due to extrusion at the bending part of the back adhesive 204, and better enables the bending and alignment pasting of the FPC 2.

[0052] The use process of the FPC side outlet structure of the display module provided by the present utility model is as follows:

[0053] By making a groove 6 on the side of the backlight rubber frame 4 to facilitate the alignment of the FPC 2, since a first rounded corner 8 is provided at the corner of the first long groove 601 and the second long groove 602, and a second rounded corner 9 is provided at the corner of the wire outlet groove 5 and the first long groove 601, and the FPC 2 is fixed inside the groove 6 through the back glue 204, it is convenient for the bending and alignment pasting of the FPC 2, avoiding the phenomenon of the FPC 2 falling off. When installed, the FPC 2 of the display screen 1 can be bent out through the groove 6 on the side, and the through groove 7 can be located on the left side, right side, upper side or lower side of the back of the backlight rubber frame 4, so that the FPC 2 can be led out from the left and right side surfaces and the upper frame side surface, thus providing multi-directional plug-in positions and angles, better meeting the market needs. And because the FPC is in the groove on the side of the backlight rubber frame, the depths of the groove 6 and the through groove 7 are both greater than the thicknesses of the FPC 2 and the back glue 204, so that the FPC 2 will not protrude from the surface of the backlight rubber frame 4, thus not affecting the assembly of the module.
