Of course, in other embodiments, based on the above-mentioned scheme that the bottom frame 310 of the backlight source has the side plate 312, and the scheme that the groove 211 is not disposed on the supporting portion 210 of the middle frame 200, the supporting portion 210 has a through hole, the through hole simultaneously penetrates through the supporting portion 210 towards one side of the display panel 100 and one side of the supporting portion 210 away from the display panel 100, and one end of the side plate 312 away from the bottom plate 311 penetrates through the through hole and is covered by the reinforcing adhesive 400. So set up, still can make reinforcement glue 400 not only can bond together center 200 and display panel 100, can also bond together backlight underframe 310 to further improve the holistic steadiness of display device, further strengthened display panel 100's mounting strength.
Or, in other embodiments, based on the above-mentioned scheme that the backlight bottom frame 310 has the side plates 312, and the grooves 211 are disposed on the supporting portions 210 of the middle frame 200, the supporting portions 210 are provided with via holes, the via holes are not communicated with the grooves 211, and one end of the side plate 312, which is away from the bottom plate 311, passes through the through hole 212 and is covered by the reinforcing adhesive 400. By such arrangement, on one hand, the injection volume of a worker during injection of the reinforcing glue 400 can be increased, so that the reinforcing glue 400 can extend into the groove 211, and the connection strength of the reinforcing glue 400 between the middle frame 200 and the display panel 100 is enhanced; on the other hand, the reinforcing glue 400 can bond the middle frame 200 and the display panel 100 together, and also can bond the backlight bottom frame 310 together, so that the overall stability of the display device is further improved, and the installation strength of the display panel 100 is further enhanced.
Further, referring to fig. 1, fig. 3, fig. 5 and fig. 7, in the first embodiment, the second embodiment and the third embodiment of the present invention, the direction from the supporting portion 210 to the display panel 100 is defined as a low-to-high direction, the display panel 100 further has a light emitting surface 102 deviating from the light incident surface 101, and the retaining wall 220 is disposed below or flush with the light emitting surface 102 of the display panel 100.
By disposing the retaining wall 220 below or flush with the light emitting surface 102 of the display panel 100, it is convenient for workers to inject the reinforcing adhesive 400 between the retaining wall 220 and the display panel 100, thereby reducing the difficulty of injection. Specifically, when the retaining wall 220 is lower than the light emitting surface 102 of the display panel 100, the top of the retaining wall 220 (i.e., the direction of the retaining wall 220 away from the supporting portion 210) has a certain operating space, and a worker can inject the reinforcing adhesive 400 between the retaining wall 220 and the side surface of the display panel 100 along a direction forming an included angle with the extending direction of the retaining wall 220, so that the reinforcing adhesive 400 is conveniently bonded with the display panel 100, the difficulty of injection can be greatly reduced, and the situation that the injection head touches the display panel 100 is reduced. Or, the height of the retaining wall 220 may be equal to the height of the light incident surface 101 of the display panel 100, and at this time, the user may inject the reinforcement adhesive 400 into the gap between the display panel 100 and the retaining wall 220, so as to ensure that the reinforcement adhesive 400 can be injected between the display panel 100 and the retaining wall 220, thereby reducing the difficulty of injection.
In this embodiment, referring to fig. 1, fig. 3 and fig. 5, in the first, second and third embodiments of the present invention, the direction from the supporting portion 210 to the display panel 100 is defined as a low-to-high direction, and the side of the reinforcement adhesive 400 departing from the supporting portion 210 is lower than or flush with the side of the retaining wall 220 departing from the supporting portion 210.
By setting the side of the reinforcement adhesive 400 away from the supporting portion 210 lower than or equal to the side of the retaining wall 220 away from the supporting portion 210, the reinforcement adhesive 400 is prevented from overflowing out of the retaining wall 220, or the reinforcement adhesive 400 is prevented from overflowing out of the display panel 100 to affect the display effect of the display panel 100.
Specifically, referring to fig. 1 to 5, the edge of the bonding glue 500 connected to the reinforcing glue 400 is serrated.
In this embodiment, the edges of the bonding glue 500 connected to the reinforcing glue 400 are zigzag, so that the connecting area between the edges of the reinforcing glue 400 and the bonding glue 500 can be increased when the edges are connected, thereby improving the connecting strength between the reinforcing glue 400 and the bonding glue 500. In addition, one side of the reinforcing glue 400 connected with the bonding glue 500 is also in a zigzag shape, so that when the edge of the reinforcing glue 400 in the zigzag shape is correspondingly connected with the display panel 100, the connection area between the reinforcing glue 400 and the display panel 100 is increased, the bonding strength between the display panel 100 and the reinforcing glue 400 is further improved, and the installation stability of the display panel 100 is improved. Specifically, the edge of the adhesive 500 may be circular arc-shaped saw-toothed, or zigzag-shaped saw-toothed.
Further, based on the scheme of connecting the reinforcing glue 400 and the adhesive glue 500, please refer to fig. 1, fig. 3, fig. 5, and fig. 7, the projection of the adhesive glue 500 on the light incident surface 101 is located on the side of the edge of the light incident surface 101 far from the retaining wall 220.
The projection of the adhesive 500 on the light incident surface 101 is located on the side, away from the retaining wall 220, of the edge of the light incident surface 101, so that a gap is reserved between the edge of the light incident surface 101 and the supporting portion 210, and further, when the reinforcement adhesive 400 is connected with the adhesive 500, the reinforcement adhesive can extend to a position between the display panel 100 and the supporting portion 210, so that the adhesion area between the reinforcement adhesive 400 and the display panel 100 is increased, the installation strength of the display panel 100 is further improved, and the display device can be allowed to be manufactured into a narrow-frame structure to a certain extent. In addition, the reinforcing glue 400 is connected with the adhesive glue 500, so that the reinforcing glue 400 and the adhesive glue 500 are integrated, the bonding strength of the reinforcing glue 400 and the adhesive glue 500 is mutually enhanced, and the bonding strength of the display panel 100 is further improved.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
