The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted.

The preferred embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the present specification.

One aspect of the present application provides a display module 10, as can be understood in conjunction with fig. 1 and 4, the display module 10 includes: a bottom shell 100 and a lamp panel 200.

A support 300 is disposed between the lamp panel 200 and the bottom housing 100, and the support 300 abuts against between the bottom housing 100 and the lamp panel 200 and is connected to the bottom housing 100 and the lamp panel 200 respectively. Support piece 300 supports and leans on support lamp plate 200, can optimize the intensity and the plane degree of lamp plate 200, makes lamp plate 200 be difficult to warp, also makes lamp plate 200's plane degree to a certain extent obtain correcting and keeping.

The lamp panel 200 is provided with a first connector 400, and the first connector 400 can be used to connect with the box body 30. Like this, the assembly between display module assembly 10 and the box 30 can use lamp plate 200 as the benchmark of location to eliminated the assembly deviation between drain pan 100 and the lamp plate 200 and to the adverse effect that the equipment between display module assembly 10 and the box 30 caused, can make the display effect of the display screen 20 of formation of assembling better.

In some embodiments, as in the example of fig. 2, the first connector 400 includes a positioning protrusion 410, the positioning protrusion 410 is disposed on and raised relative to a surface of the lamp panel 200, and the positioning protrusion 410 is configured as a first magnetic attraction portion that can be used for magnetic attraction connection. As shown in fig. 5, the positioning protrusion 410 can be inserted into the positioning hole 32 of the box body 30 to position the lamp panel 200 and the box body 30 and magnetically connect with the box body 30. Wherein, still be limited with supporting surface 210 on lamp plate 200, when location convex part 410 inserts in the locating hole 32 and with box 30 magnetism inhale and be connected, supporting surface 210 corresponds and supports the boss 33 position with box 30 and lean on. Like this, location convex part 410 and locating hole 32 are pegged graft the cooperation, can restrict the relative motion along upper and lower direction and left and right directions between box 30 and the lamp plate 200, and location convex part 410 is inhaled a magnetism with box 30 as first magnetism and is connected, can restrict the relative motion along the fore-and-aft direction between box 30 and the lamp plate 200 to realize that the equipment is reliable and stable between lamp plate 200 and the box 30, and have simple structure, the convenient advantage of equipment.

Alternatively, as can be understood from fig. 6 and 7, the surface of the lamp panel 200 at the position on the circumferential side of the positioning convex portion 410 is formed as the support surface 210. Like this, the support face 210 supports with the support boss 33 of box 30 and leans on to make between lamp plate 200 and the box in the time of spacing from beginning to end, can make lamp plate 200 be located the position around locating convex part 410 and obtain to support and lean on to strengthen, can compensate lamp plate 200 like this to a certain extent because the tensile stress deformation that the connection received is inhaled to locating convex part 410 magnetism to ensure lamp plate 200's intensity and plane degree better.

In some embodiments, as can be understood from fig. 6 and 7, an avoiding hole 101 is formed in the bottom case 100, the positioning protrusion 410 passes through the avoiding hole 101, a space is formed between the positioning protrusion 410 and a side wall surface of the avoiding hole 101, and a gap between the positioning protrusion 410 and the side wall surface of the avoiding hole 101 corresponds to the position of the supporting surface 210, as shown in fig. 5, the gap between the positioning protrusion 410 and the side wall surface of the avoiding hole 101 can be used for the supporting boss 33 to pass through. Can realize that holding surface 210 is corresponding and support boss 33 position of box 30 and lean on like this, avoid lamp plate 200 and the influence that receives drain pan 100 in the box 30 connection process, thereby the influence of drain pan 100 and lamp plate 200 assembly deviation has been eliminated, and location convex part 410 and support boss 33 dodge through dodging hole 101, dodge hole 101 and can effectively protect location convex part 410 and support boss 33, promote product reliability, and this structure also does benefit to the display screen attenuate that the equipment formed.

In some embodiments, a protrusion height of the positioning convex portion 410 with respect to the surface of the lamp panel 200 (the protrusion height may also be understood as a height dimension of the positioning convex portion 410 from an end connected to the lamp panel 200 to an end away from the lamp panel 200) is smaller than a distance between the end of the avoidance hole 101 away from the lamp panel 200 and the lamp panel 200. Thus, as shown in fig. 13, when the positioning protrusion 410 is inserted along one end of the avoiding hole 101, the positioning protrusion will not substantially penetrate out of the other end of the avoiding hole 101, and the avoiding hole 101 can avoid the positioning protrusion 410 from being damaged during the transferring or transporting process of the display module 10.
