Technical Field

[0001] The utility model relates to the technical field of liquid crystal display, and in particular to a display module and a display device. Background Art

[0002] After the display module using IPS (In-Plane Switching) technology is assembled, due to the gravity, stress and local unevenness of the panel, black screen and oppressive light leakage will appear. In the prior art, in order to solve the above problems, the display module often uses foam glue as a buffer substrate. Figure 1 is a schematic diagram of a display module provided by the prior art, such as Figure 1 As shown, a certain thickness of foam glue 4 is provided between the front frame 1 and the panel assembly 2, and between the panel assembly 2 and the middle frame 3. Usually, the foam glue 4 is provided with a thickness of 0.5 mm. However, for a display module with a narrow front frame, after using the foam glue 4, the gap between the panel assembly 2 and the film layer 5 becomes larger, thereby making the front frame line of the display module poor and the quality of the four sides of the display module worse.

[0003] Therefore, a new display module is urgently needed to solve the above problems. Utility Model Content

[0038] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0039] Figure 2 Schematic diagram of a display module provided by a specific embodiment of the utility model; Figure 2 As shown, this embodiment provides a display module, which includes a back panel 100, a membrane layer assembly 200, a middle frame 300 and a panel assembly 500, the back panel 100 includes a back panel base plate 110 and a back panel side plate 120 upright on the back panel base plate 110; the membrane layer assembly 200 is arranged inside the back panel 100; the middle frame 300 is abutted against the top of the back panel side plate 120, and a buffer component 410 is sandwiched between the middle frame 300 and the back panel side plate 120; the panel assembly 500 is arranged on the top of the middle frame 300, a first shock absorbing component 420 is sandwiched between the panel assembly 500 and the middle frame 300, and a gap layer 440 is arranged between the panel assembly 500 and the membrane layer assembly 200.

[0040] By sandwiching a buffer 410 between the middle frame 300 and the back plate 100, and sandwiching a first shock absorber 420 between the panel assembly 500 and the middle frame 300, the buffer 410 and the first shock absorber 420 ensure sufficient shock absorption of the panel assembly 500, and avoid the problem of oppressive light leakage of the black screen caused by the panel assembly 500 being subjected to gravity, stress and local unevenness of the sheet metal. At the same time, by adding a buffer 410 between the middle frame 300 and the back plate 100 to cooperate with the first shock absorber 420 for shock absorption, the thickness of the first shock absorber 420 can be less than the thickness of the foam glue in the prior art, thereby reducing the thickness of the gap layer 440 between the panel assembly 500 and the membrane layer assembly 200, thereby improving the four-sided display taste of the display module and thus improving the user experience.

[0041] Specifically, the buffer 410 is set to rubber; and the thickness of the buffer placed between the middle frame 300 and the back panel side plate 120 is set to 0.5mm-2mm. At the same time, the thickness of the first shock absorber 420 is set to 0.3mm, which is 0.2mm less than the thickness of the foam glue in the prior art. In addition, since the additional buffer 410 can play a better buffering and shock absorbing effect, the first shock absorber 420 can be set to PET material.

[0042] In this embodiment, the middle frame 300 includes a middle frame bottom plate 310 and a middle frame side plate 320 bent downward relative to the middle frame bottom plate 310. The connection between the back plate side plate 120 and the middle frame side plate 320 is realized, and the membrane layer assembly 200 is arranged on the inner side of the back plate 100. It is worth noting that in order to enable the buffer 410 to reduce the problems of gravity, stress and local unevenness of the sheet metal on the panel assembly 500, the buffer 410 is arranged between the back plate side plate 120 and the middle frame side plate 320, and the first shock absorbing member 420 is arranged on the middle frame bottom plate 310 and the panel assembly 500. Optionally, the first shock absorbing member 420 is connected to the middle frame bottom plate 310 and the panel assembly 500 by gluing. In addition, the middle frame 300 and the back panel 100 connected by the back panel side panel 120 and the middle frame side panel 320 can reduce the single-side width by 0.4 mm compared with the prior art, which is conducive to the setting of a narrow front frame and increases the display area.

Optionally, the supporting part 412 is bonded to the inner side of the back panel side plate 120 and the middle frame side plate 320, as well as the back panel bottom plate 110 and the middle frame bottom plate 310.

[0046] Preferably, the positioning groove 121 is set to be a quadrilateral, the positioning protrusion 321 is set to be wedge-shaped, and the width close to the bottom of the positioning groove 121 is smaller than the width away from the bottom of the positioning groove 121. The positioning protrusion 321 with a wedge-shaped setting, on the one hand, provides guidance for the cooperation between the positioning groove 121 and the positioning protrusion 321 when installing the middle frame 300; on the other hand, it can also ensure that the shock absorbing part 411 of the buffer 410 has a suitable deformation, so that it has a suitable interference to ensure that the connection between the positioning groove 121 and the positioning protrusion 321 is reliable and has a certain shock absorption. In other embodiments, the positioning protrusion 321 can also be set on the back panel side plate 120, and the positioning groove 121 can be set on the middle frame side plate 320.
