[0033] Figure 1 The existing structure of the display module is illustrated. The back plate 110' is an F-shaped folded edge structure with two steps. A display panel is set on one of the steps. A buffer 130', such as a buffer foam, is set between the display panel 120' and the step. The optical component 140' is set on the non-display side of the display panel, located at the other step. In this structure, since a step is required to support the display panel, the molding process of the back plate structure is complicated. At the same time, stamping and splicing cannot be completed at the corners, and the corners need to be sealed by welding or additional corner pieces.
[0034] Therefore, in order to simplify the structure of the back plate 110, reduce the molding process of the back plate 110, and reduce the use of splicing corner pieces, the embodiment of the present application provides a display module. Figure 2 As shown, the display module provided in the embodiment of the present application includes:
[0035] A back plate 110, wherein the back plate 110 has a support surface 111;
[0036] An optical component 140, wherein the optical component 140 is disposed on the supporting surface 111;
[0037] A buffer member 130, wherein the buffer member 130 has a first side surface 131 and a second side surface 132 which are arranged opposite to each other; the first side surface 131 is in contact with the supporting surface 111;
[0038] The display panel 120 is arranged opposite to the back plate 110 and has a fixing surface 121 facing the supporting surface 111 , and the fixing surface 121 is attached to the second side surface 132 ; wherein the thickness of the buffer 130 is greater than the thickness of the optical component 140 .
[0039] In the technical solution of the embodiment of the present application, the fixed surface 121 of the display panel 120 facing the back plate 110 is attached to the second side surface 132 of the buffer 130, and the first side surface 131 of the buffer 130 opposite to the second side surface 132 is arranged on the support surface 111 of the back plate 110. At the same time, an optical component 140 is also provided on the support surface 111, so that the optical component 140 and the display panel 120 are jointly arranged on the same support surface 111 of the back plate 110. At the same time, the thickness of the buffer 130 is greater than the thickness of the optical component 140, ensuring that the buffer 130 can effectively support the display panel 120; therefore, in the display module provided in the embodiment of the present application, the back plate 110 does not need to be set as two step structures, that is, the back plate 110 does not need to be set as an F-type structure, thereby simplifying the structure of the back plate 110, reducing the molding process of the back plate 110, and reducing the use of splicing corner pieces.
[0040] In some prior arts, since the back panel 110 is set as an F-shaped structure, it is necessary to set a Mylar or rubber strip on the F-folded plane; however, in the technical solution of the present application, since the back panel 110 does not need to be set as an F-shaped structure, it is not necessary to set a Mylar or rubber strip structure, which can simplify the process of the display module and reduce material and process costs.
[0041] like Figure 2 As shown, the display module has a display side, and the fixing surface 121 of the display panel 120 is the opposite surface of the display side.
[0042] In an embodiment, the display panel 120 may be a liquid crystal panel.

The first adhesive layer 134 is glued to the supporting surface 111, and the second adhesive layer 135 is glued to the fixing surface 121.
[0044] As an optional implementation of the above embodiment, the buffer 130 further has a third side surface 133, and the third side surface 133 is respectively connected to the first side surface 131 and the second side surface 132; at least one end surface of the optical component 140 is configured to be abutted against the third side surface 133. In this embodiment, at least one end surface of the optical component 140 is abutted against the third side surface 133, and the buffer 130 can also provide limited support for the optical component 140 when fixing the display panel 120.
[0045] In the embodiment, the third side surface 133 extends from the first side surface 131 to the second side surface 132 in the thickness direction. Generally speaking, the third side surface 133 is a side of the buffer 130 in the width direction thereof.
[0046] In an embodiment, the end surface of the optical component 140 may be an end surface in the length direction or an end surface in the width direction thereof.
[0047] As an optional implementation of the above embodiment, the optical assembly 140 includes a diffuser 141 and an optical film 143 and a reflective sheet 142 disposed on opposite sides of the diffuser 141; the optical film 143 faces the fixed surface 121, and the reflective sheet is disposed on the support surface 111. In the embodiment, the optical film 143 and the reflective sheet can be pasted on both sides of the diffuser 141; in some embodiments, the optical film 143 can be set as an integral structure with the diffuser 141, and the reflective sheet 142 is pasted on the side of the diffuser 141 away from the optical film 143. In the embodiment, the optical film 143 is disposed facing the fixed surface 121 of the display panel 120; the reflective sheet 142 is disposed on the support surface 111, and the optical assembly 140 is supported by the back plate 110. In the embodiment, the optical film 143 is a brightness enhancement film, the diffuser 141 evens the light of the light source in the display module, and the reflective sheet 142 reflects the light.
[0048] As an optional implementation of the above embodiment, Figure 4 As shown, the display module has a sky side and a ground side that are arranged opposite to each other. The sky side and the ground side are generally two sides of the display module in the height direction. The end face of the optical component 140 includes a sky side end face 144 located on the sky side and a ground side end face 145 located on the ground side, the sky side end face 144 can abut against the third side face 133 located on the sky side, and the ground side end face 145 is fixed on the back plate 110.
[0049] In an embodiment, the buffer 130 is disposed on the sky side of the display module. The sky side end face 144 of the optical component 140 can abut against the third side face 133 located on the sky side, and the ground side end face 145 of the optical component 140 is fixed on the back plate 110 to fix the optical component 140. The sky side end face 144 of the optical component 140 can abut against the third end face on the sky side, thereby limiting the excessive movement of the optical component 140 in the height direction. Limiting the movement of the optical component 140 is understood as: when the optical component 140 expands, it can abut against the third end face on the sky side, and the optical component 140 compresses the buffer 130. Since the buffer 130 has a certain hardness, the excessive movement of the optical component 140 can be avoided.

[0051] In some embodiments, the optical component 140 and the third side surface 133 may be matched with zero clearance or with a small clearance (eg, 0.3 mm to 1.3 mm, further such as 0.3 mm, 0.5 mm, 1.0 mm, or 1.2 mm).
[0052] In some other embodiments, the top-side end surface 144 is glued to the third side surface 133 located on the top side.

[0053] In some technical solutions of the embodiments of the present application, the optical component 140 has a sky side edge located at the sky side and a ground side edge located at the ground side; the sky side edge and / or the ground side edge are glued to the support surface 111. Figure 4 As shown, the diffuser 141 is provided with a fourth adhesive layer 150 at the upper edge and / or the lower edge. The fourth adhesive layer 150 is provided on the supporting surface 111 , thereby fixing the position of the optical component 140 .
[0054] In the embodiment, the optical component 140 has a side facing away from the display panel 120 , and the fourth adhesive layer 150 is disposed on the side and located at the top edge of the side close to the top end surface 144 and / or the bottom edge of the side close to the bottom end surface 145 .

[0057] In some embodiments, the diffuser 141 has no fourth adhesive layer 150 at the ground side edge, but has a fourth adhesive layer 150 at the sky side edge, and the ground side end surface 145 is fixed to the edge of the back plate 110 at the sky side.
