The

20 includes a

220, a

240, a

260 and a

280.

The

220 is a protective structure for protecting the outermost side of the

20. The

220 may be made of tempered glass or the like.

The

240 abuts the

220.

The

260 is disposed on a side of the

240 away from the

220, the

260 has a

262 facing the

220, the

262 is disposed on a side of the

240 and used for protecting the

240, and a gap 264 is disposed between the

262 and the

220.

The

280 is disposed in the gap 264 and connects the

262 and the

220. In a falling or other cases, the cover plate is subjected to an impact force (e.g., an impact force perpendicular to the cover plate), because the

280 is connected with the

262 and the

220, the

280 and the

260 having the

262 are matched to support the

220, and simultaneously, the

240 and the

260 are matched to also support the

220 and share the impact force of the

220, so that the impact force is well dispersed, the

220 is protected from being easily broken, and the probability of breakage of the cover plate is reduced.

The display module can be an LCD display module, an OLED display module or other display modules. Referring to fig. 4 and fig. 5, fig. 4 is a schematic diagram of a third partial structure of a display device according to an embodiment of the present application, and fig. 5 is a schematic diagram of a fourth partial structure of the display device according to the embodiment of the present application. When the display module is a liquid crystal display module, the

240 may include a

242 and a

244, the

242 includes liquid crystal, the

244 includes a supporting

2442 exceeding the

242, a driving circuit may be disposed on the supporting

2442, and the driving circuit may be configured to drive the

242, may also be configured to drive other modules (such as a touch module) of the

20, and may also be configured as needed. The

20 further includes some

246, some of the

246 are disposed between the supporting

2442 and the

260, and the side of the supporting

2442 that is beyond the

242 and faces the

220 is not abutted by the

242, which can also be understood as a state where the supporting

2442 is suspended, and is a single layer of glass, and the thickness of the

244 is about 0.1 mm to 0.4 mm, which is relatively fragile. In some embodiments, the display module may include an array substrate and a color film substrate, a plurality of functional layers such as a liquid crystal layer are disposed between the array substrate and the color film substrate, the plurality of functional layers are used as a display layer of the display module, and the plurality of functional layers are provided with a driving circuit, the driving circuit is not only disposed in the functional layers, but also needs to be connected to an external driving chip, so that the array substrate or the color film substrate has a portion that exceeds the display layer, the portion is used as a bearing portion, and the driving circuit in the display layer is electrically connected to the external driving chip through the driving circuit on the bearing portion. The array substrate or the color filter substrate with the bearing portion is the glass substrate in the above embodiment.

The

262 of the

260 is at least partially disposed opposite to the supporting

2442, and it can also be understood that the

262 of the

260 is disposed corresponding to the supporting

2442. The

20 requires the

260 and the

240 to cooperate to display images, the edge of the

260 corresponding to the supporting

2442 has a

262, and the

262 can protect the supporting

2442 and prevent the supporting

2442 from being broken by an impact force perpendicular to the protrusion direction (which can also be understood as an impact force parallel to the cover plate direction).

Because there is tolerance in the mold injection of the

260, and thickness tolerance in the assembly process of each layer of the

240, in order to prevent the interference between the

262 and the

220 and the light leakage at the bottom edge caused by the jacking up of the

240, a certain gap must be reserved between the

220 and the

262. In addition, considering the industrial process capability comprehensively, a gap of 0.05 mm-0.1 mm is reserved between the protruding

262 and the

220 to avoid interference. The gap may have product in excess of 0.1 mm due to process fluctuations and the like.

The

280 is disposed in the gap 264 and connects the

262 and the

220. In a dropping or other situations, the

260 receives a Z-direction (perpendicular to the cover plate) impact force on one side, because the

280 connects the

262 and the

220, the

260, the

220 and the

240 are deformed integrally, the deformation of the

244 having the

2442 in the

240 is limited, and the

244 is not easily broken due to the deformation. Without the filler, the gap between the protrusion and the cover plate is too large, and the

2442 does not support effectively in the presence of external force. The load bearing

2442 is deformed excessively, and is very likely to be broken due to the excessively large amount of deformation, resulting in failure of the display device.

In this embodiment, the

260 and the

262 thereof cooperate with the

220 to protect the

244 having the supporting

2442 in the horizontal direction (i.e., parallel to the cover plate direction), and the

280 connects the

262 of the

260 and the

220 to protect the

244 having the supporting

2442 in the Z direction (i.e., perpendicular to the cover plate direction), so as to enhance the protection of the

244 having the supporting

2442, reduce the failure probability of the

20, and enhance the anti-drop performance of the

20.

Wherein the filling

280 may be formed of glue. It should be noted that the glues have a certain fluidity, but at the same time have a relatively high viscosity to each other, and do not flow like water. The glue may fill the gap, and the glue after filling the gap cures to form the

280, and the

280 connects the

262 and the

220.

Glue can also be filled into the gap without a jig. Specifically, please refer to fig. 6 and 7, fig. 4 is a schematic diagram of a fifth partial structure of the display device according to the embodiment of the present application, and fig. 7 is a schematic diagram of a sixth partial structure of the display device according to the embodiment of the present application. The

262 has a

2622 and a

2624 opposite to the

2622, the

2622 faces the

220, the

262 has a through

2626 penetrating the

2622 and the

2624, the through

2626 communicates with the gap, and the filling

280 is further disposed in the through

2626. Glue can be located the opening position injection of

2624 from through-

2626, then flows into the clearance through-

2626, and through-

2626 can be roughly perpendicular to

220, conveniently irritates glue, and through-

2626's size can be far more than the clearance in addition, need not set up very little nozzle or other tool again, just can irritate through-

2626 to glue. The glue has certain mobility, and the glue naturally flows to the gap to fill up the gap, and glue is also stored in the through

2626 above the gap, and when the glue in the gap flows outwards, the glue in the through

2626 can also be supplemented into the gap to ensure that the gap is filled up with the glue before curing, and the gap is also filled up with the

280 after the glue is cured, so that the gap cannot be filled up with the

280 after curing due to the mobility of the glue.

The filling

280 may include a

282 and a

284, the first filling

282 is located in the through

2626, the

284 is located between the

2622 and the

220, and an area of an orthographic projection of the

284 on the

220 is larger than an area of an orthographic projection of the first filling

282 on the

220. After the glue is injected into the through

2626 and flows into the gap, the glue can diffuse and flow outwards in the gap to fill the gap and flow out of the region corresponding to the

262, so that the glue can still fill the gap during the glue curing process, and a gap between the glue and the

2622 of the

262 cannot exist due to the flowability of the glue.

It should be noted that the type of the glue may be selected from materials with high viscosity, high stability and proper fluidity, and the curing mode may be natural air drying or ultraviolet curing. After the glue is cured, the glue is adhered and fixed with one side of the

220 facing the

260. The protruding

262 of the

260 is integrally connected to the

220 by the cured glue (i.e., the filling material).

The dimensions of the different locations in the through hole may be equal, i.e. the through hole may be understood as cylindrical. Referring to fig. 8, in particular, fig. 8 is a schematic diagram illustrating a seventh partial structure of a display device according to an embodiment of the present disclosure. The through

2626 includes a

2623 on the

2622 and a

2625 on the

2624, the size of the

2625 being larger than the size of the

2623, and the size of the through

2626 being smaller from the

2625 to the

2623. The

2625 is sized to facilitate injecting glue. In other embodiments, the size of the second opening may be smaller than that of the first opening, and the size of the through

2626 may be larger from the second opening to the first opening. The glue can be conveniently and quickly filled into the gap.

The area of the first surface and the area of the second surface of the protruding part may be substantially equal or unequal. Referring to fig. 9 in detail, fig. 9 is a schematic diagram of an eighth partial structure of a display device according to an embodiment of the present application. When the area of the

2622 is larger than that of the

2624, the area of the

2622 is larger, and more glue can be carried, so that the area of the filling

280 is larger, the contact area with the

220 is larger, and the Z-direction impact force is better dispersed. It should be noted that the area of the first surface is larger, and the opening of the through hole on the first surface may be larger.

The protrusion may be provided with a groove in addition to the through hole, that is, the groove in the present embodiment may replace the through hole in the above-described embodiment. Referring to fig. 10 and fig. 11 in detail, fig. 10 is a schematic diagram of a ninth partial structure of a display device according to an embodiment of the present application, and fig. 11 is a schematic diagram of a protruding portion in the display device shown in fig. 10. The

266 in the

262 communicates with the gap and a

280 is also provided in the

266. It will be appreciated that glue may be injected into the

266 and then flow into the gap along the

266.

Wherein the

262 includes a bottom wall that forms the bottom of the

266 and side walls that form the sides of the

266. The

266, where the

266 is opposite the bottom wall, may open toward the

2442 or away from the

2442.

If

266 opens away from

2442, it will also be understood that

266 opens out of

20, and the side walls have a gap communicating with the gap, and the glue generator can conveniently inject glue through the opening of

266, forming a bottom wall at the bottom of

266 that allows glue to flow down

266 and through the gap into the gap. Groove 266 may also have another indentation disposed on

2624, and glue may be injected through the indentation of

2624. It will also be appreciated that the

266 may be in communication with the gap at one end and may be located intermediate the projections at the other end, in which case glue may be injected from the opening of the groove. One end of the

266 is connected to the gap and the other end can penetrate the

2624 of the protrusion, at which time glue can be injected from the opening of the groove or from the notch of the second face (notch of the groove).
