[0043] Combination Figure 1 and Figure 2 As shown, in one or more embodiments, the present application provides a display module, which includes: a middle frame 101, a back panel 102, a light guide plate 103 and a diaphragm 104; the middle frame 101 includes a first pressure plate 105; the back panel 102 is fixedly connected to the middle frame 101, the back panel 102 includes a main panel 106 and side panels 107, the side panels 107 are fixedly connected to the main panel 106, and a limiting space 108 is formed between the main panel 106 and the first pressure plate 105; the light guide plate 103 is arranged in the limiting space 108; the diaphragm 104 and the light guide plate 103 are stacked, the side surface of the diaphragm 104 in the thickness direction is opposite to the side surface of the first pressure plate 105 in the thickness direction, the diaphragm 104 and the first pressure plate 105 are located on the same side of the light guide plate 103, and the diaphragm 104 is connected to the side panels 107.

[0044] The display module provided in the present application utilizes a first pressing plate 105 and a main panel 106 to clamp the light guide plate 103 in a limiting space 108, thereby limiting the light guide plate 103 in the thickness direction of the display module; and the membrane plate is connected to the side plate 107 to reduce the shaking of the membrane plate; the membrane 104 and the first pressing plate 105 are located on the same side of the light guide plate 103, which is beneficial to reducing the overall thickness of the display module and facilitating the thinning design of the display module.

[0045] Combination Figure 1 and Figure 2 As shown, in some embodiments, the width direction of the display module is the AA direction, the height direction of the display module is the BB direction, and the thickness direction of the display module is the CC direction. The width direction of the display module, the height direction of the display module, and the thickness direction of the display module are perpendicular to each other. The display module can be a liquid crystal display module, such as a liquid crystal display; the edge area of ​​the light guide plate 103 is inserted into the limiting space 108, the first pressing plate 105 is attached to one side of the light guide plate 103, and the diaphragm 104 is attached to one side of the light guide plate 103, so that the first pressing plate 105 and the diaphragm 104 are located on the same layer, which is conducive to the thinning of the thickness of the display module; and when the first pressing plate 105 and the diaphragm 104 are located on the same layer, the diaphragm 104 is connected to the side plate 107, so that the positioning of the side plate 107 is achieved, and its shaking is reduced, thereby ensuring the stability of the display module after thinning.

[0046] Combination Figures 1 to 3As shown, in some embodiments, the display module further includes a reflective sheet 109, and the reflective sheet 109 is located between the main panel 106 and the light guide plate 103. The reflective sheet 109 can completely reflect the light or weaken the reflection, or perform a shielding effect such as interference. Exemplarily, the reflective sheet 109 is attached to the other side opposite to the light guide plate 103, and the reflective sheet 109 is also attached to the main panel 106, so that the reflective sheet 109 can also be supported by the back plate 102; and after the reflective sheet 109 is combined, the light guide plate 103 can be limited and fixed in the thickness direction of the display module, reducing the possibility of its shaking.

[0047] See also Figure 1 As shown, in some embodiments, the display module further includes a liquid crystal panel 110 and a touch screen 111, and the liquid crystal panel 110 is located between the touch screen 111 and the membrane 104. In this way, the touch screen 111 is located at the top layer as a user interaction interface; and the liquid crystal panel 110 is located below the touch screen 111, and realizes the display of images by controlling the arrangement direction of liquid crystal molecules.

The limiting insert 113 is inserted into the limiting plug hole 112 so that the diaphragm 104 is connected to the side plate 107. In this way, the cooperation between the limiting insert 113 and the limiting plug hole 112 can reduce the shaking of the diaphragm 104.

In this way, the shaking of the diaphragm 104 in the width direction and the height direction of the display module can be reduced. Exemplarily, the first sub-panel 114 and the main panel 106 are an integral structure, for example, made by an integral molding process; the diaphragm 104 has a protrusion 116 on one side of the height direction of the display module, and the limiting plug hole 112 is opened on the protrusion 116, so that the protrusion 116 can not affect the function of the main part of the diaphragm 104; when the side surface of the protrusion 116 in the thickness direction abuts against the middle frame 101, the shaking of the diaphragm 104 in the width direction of the display module can be further reduced. The number of the protrusions 116 can be one or more. When the number of the protrusions 116 is multiple, such as the number of the protrusions 116 is two, three or four, the specific number can be determined according to actual conditions. In this way, a limiting hole 112 is set on each protrusion 116, and a limiting plug 113 equal to the number of the protrusions 116 is set on the side plate 107, which can further ensure the stability of the diaphragm 104.

The limiting plug 113 on the second sub-board 115 cooperates with the limiting hole 112 on the protrusion 116 on one side in the width direction of the display module of the diaphragm 104, so that the diaphragm 104 can be better positioned.

The third sub-plate 117 and the two fourth sub-plates 118 enclose an insertion area 119, and the insertion area 119 is for inserting the diaphragm 104, so that the insertion area 119 can also limit the diaphragm 104. The third sub-board 117 is provided with an escape notch 120 , which can provide an escape space for the protrusion 116 on one side of the diaphragm 104 in the height direction of the display module, so as to facilitate the matching of the limiting plug hole 112 on the protrusion 116 with the limiting plug 113 on the first sub-board 114 .
