Thedisplay device 20 includes acover plate 220, adisplay module 240, abacklight module 260 and afilling body 280.

Thecover plate 220 is a protective structure for protecting the outermost side of thedisplay device 20. Thecover plate 220 may be made of tempered glass or the like.

Thedisplay module 240 abuts thecover plate 220.

Thebacklight module 260 is disposed on a side of thedisplay module 240 away from thecover plate 220, thebacklight module 260 has aprotrusion 262 facing thecover plate 220, theprotrusion 262 is disposed on a side of thedisplay module 240 and used for protecting thedisplay module 240, and a gap 264 is disposed between theprotrusion 262 and thecover plate 220.

Thefilling body 280 is disposed in the gap 264 and connects theprotrusion 262 and thecap plate 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 thefiller 280 is connected with theprotrusion 262 and thecover plate 220, thefiller 280 and thebacklight module 260 having theprotrusion 262 are matched to support thecover plate 220, and simultaneously, thedisplay module 240 and thebacklight module 260 are matched to also support thecover plate 220 and share the impact force of thecover plate 220, so that the impact force is well dispersed, thecover plate 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, thedisplay module 240 may include adisplay layer 242 and aglass substrate 244, thedisplay layer 242 includes liquid crystal, theglass substrate 244 includes a supportingportion 2442 exceeding thedisplay layer 242, a driving circuit may be disposed on the supportingportion 2442, and the driving circuit may be configured to drive thedisplay layer 242, may also be configured to drive other modules (such as a touch module) of thedisplay device 20, and may also be configured as needed. Thedisplay device 20 further includes somefunctional modules 246, some of thefunctional modules 246 are disposed between the supportingportion 2442 and thebacklight module 260, and the side of the supportingportion 2442 that is beyond thedisplay layer 242 and faces thecover plate 220 is not abutted by thedisplay layer 242, which can also be understood as a state where the supportingportion 2442 is suspended, and is a single layer of glass, and the thickness of theglass substrate 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.

Theprotruding portion 262 of thebacklight module 260 is at least partially disposed opposite to the supportingportion 2442, and it can also be understood that theprotruding portion 262 of thebacklight module 260 is disposed corresponding to the supportingportion 2442. Thedisplay device 20 requires thebacklight module 260 and thedisplay module 240 to cooperate to display images, the edge of thebacklight module 260 corresponding to the supportingportion 2442 has aprotrusion 262, and theprotrusion 262 can protect the supportingportion 2442 and prevent the supportingportion 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 thebacklight module 260, and thickness tolerance in the assembly process of each layer of thedisplay module 240, in order to prevent the interference between theprotrusion 262 and thecover plate 220 and the light leakage at the bottom edge caused by the jacking up of thedisplay module 240, a certain gap must be reserved between thecover plate 220 and theprotrusion 262. In addition, considering the industrial process capability comprehensively, a gap of 0.05 mm-0.1 mm is reserved between the protrudingpart 262 and thecover plate 220 to avoid interference. The gap may have product in excess of 0.1 mm due to process fluctuations and the like.

Thefilling body 280 is disposed in the gap 264 and connects theprotrusion 262 and thecap plate 220. In a dropping or other situations, thebacklight module 260 receives a Z-direction (perpendicular to the cover plate) impact force on one side, because thefiller 280 connects theprotrusion 262 and thecover plate 220, thebacklight module 260, thecover plate 220 and thedisplay module 240 are deformed integrally, the deformation of theglass substrate 244 having thebearing portion 2442 in thedisplay module 240 is limited, and theglass substrate 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 thebearing portion 2442 does not support effectively in the presence of external force. The load bearingportion 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, thebacklight module 260 and theprotrusion 262 thereof cooperate with thecover plate 220 to protect theglass substrate 244 having the supportingportion 2442 in the horizontal direction (i.e., parallel to the cover plate direction), and thefiller 280 connects theprotrusion 262 of thebacklight module 260 and thecover plate 220 to protect theglass substrate 244 having the supportingportion 2442 in the Z direction (i.e., perpendicular to the cover plate direction), so as to enhance the protection of theglass substrate 244 having the supportingportion 2442, reduce the failure probability of thedisplay device 20, and enhance the anti-drop performance of thedisplay device 20.

Wherein the fillingbody 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 thefilling body 280, and thefilling body 280 connects theprotrusion 262 and thecap plate 220.

Filling the glue into the gap can be realized by matching with a jig, and then curing the glue to form a filling body. Exemplarily, the tool can include a hourglass hopper-shaped gluey portion of gluing and a tubulose some department of gluing, and the injecting glue portion includes that the first port that the bore is big and the second port that the bore is little, and the first port is used for receiving glue, and the second port tie point is glued the portion, and the diameter of some portion of gluing is little, can set up in the clearance or the clearance limit, makes things convenient for glue to pour into in the clearance. Wherein, injecting glue portion can become certain angle with some gluey portion, for example between 90 degrees to degree 150 degrees, can make things convenient for the glue generater to place.

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. Theprotrusion 262 has afirst face 2622 and asecond face 2624 opposite to thefirst face 2622, thefirst face 2622 faces thecover plate 220, theprotrusion 262 has a throughhole 2626 penetrating thefirst face 2622 and thesecond face 2624, the throughhole 2626 communicates with the gap, and the fillingmember 280 is further disposed in the throughhole 2626. Glue can be located the opening position injection ofsecond face 2624 from through-hole 2626, then flows into the clearance through-hole 2626, and through-hole 2626 can be roughly perpendicular toapron 220, conveniently irritates glue, and through-hole 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-hole 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 throughhole 2626 above the gap, and when the glue in the gap flows outwards, the glue in the throughhole 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 thefiller 280 after the glue is cured, so that the gap cannot be filled up with thefiller 280 after curing due to the mobility of the glue.

The fillingbody 280 may include afirst filling part 282 and asecond filling part 284, the first fillingpart 282 is located in the throughhole 2626, thesecond filling part 284 is located between thefirst face 2622 and thecover plate 220, and an area of an orthographic projection of thesecond filling part 284 on thecover plate 220 is larger than an area of an orthographic projection of the first fillingpart 282 on thecover plate 220. After the glue is injected into the throughhole 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 theprotrusion 262, so that the glue can still fill the gap during the glue curing process, and a gap between the glue and thefirst surface 2622 of theprotrusion 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 thecover plate 220 facing thebacklight module 260. The protrudingportion 262 of thebacklight module 260 is integrally connected to thecover plate 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 throughhole 2626 includes afirst opening 2623 on thefirst side 2622 and asecond opening 2625 on thesecond side 2624, the size of thesecond opening 2625 being larger than the size of thefirst opening 2623, and the size of the throughhole 2626 being smaller from thesecond opening 2625 to thefirst opening 2623. Thesecond opening 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 throughhole 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 thefirst surface 2622 is larger than that of thesecond surface 2624, the area of thefirst surface 2622 is larger, and more glue can be carried, so that the area of the fillingbody 280 is larger, the contact area with thecover plate 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 through hole may also have other configurations, for example, the through hole may include two parts, that is, the through hole includes a first part and a second part which are adjacent to each other, the first part penetrates through the second surface, and the size of the first part is larger than that of the second part. The first part of the through hole penetrates through the second surface of the protruding part, and the first part is larger in size, so that a nozzle for spraying glue can conveniently enter the first part, or more glue sprayed by the nozzle can conveniently enter the through hole.

In other embodiments, the first portion may extend through the first face, and the first portion may have a size greater than the second portion. The size that the first portion of through-hole run through the first face of protruding portion is bigger, can make things convenient for glue to flow into the clearance, increases the area of contact of glue and the lateral wall that forms the through-hole moreover, increases the joint strength between glue and the protruding portion.

The through hole may further include three portions, the through hole including a first portion, a second portion, and a third portion, the third portion connecting the first portion through the second portion, the first portion penetrating the second face, a size of the first portion being larger than a size of the second portion, the third portion penetrating the first face, a size of the third portion being larger than a size of the second portion.

The third part runs through the first face of the protruding part in the through hole, and the size of the third part is larger, so that glue can conveniently flow into the gap, the contact area between the glue and the side wall of the through hole is increased, and the connection strength between the glue and the protruding part is increased. Wherein the first portion and the third portion may or may not be the same size.

The sizes of the different positions of the first part, the second part and the third part of the through hole in the above embodiments may be equal or unequal.

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. Therecess 266 in theprojection 262 communicates with the gap and afiller 280 is also provided in therecess 266. It will be appreciated that glue may be injected into thegroove 266 and then flow into the gap along thegroove 266.

Wherein theprojection 262 includes a bottom wall that forms the bottom of therecess 266 and side walls that form the sides of therecess 266. Therecess 266, where therecess 266 is opposite the bottom wall, may open toward thecarrier portion 2442 or away from thecarrier portion 2442.

Ifgroove 266 opens away fromcarrier 2442, it will also be understood thatgroove 266 opens out ofdisplay device 20, and the side walls have a gap communicating with the gap, and the glue generator can conveniently inject glue through the opening ofgroove 266, forming a bottom wall at the bottom ofgroove 266 that allows glue to flow downgroove 266 and through the gap into the gap. Groove 266 may also have another indentation disposed onsecond face 2624, and glue may be injected through the indentation ofsecond face 2624. It will also be appreciated that thegroove 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 thegroove 266 is connected to the gap and the other end can penetrate thesecond face 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).

Note that the glue may be a transparent Clear Adhesive (OCA). The optical cement is solid cement with high optical transmittance and is used for bonding the display screen and the protective glass. The glue may also be an opaque glue, for example, a melanin doped optical glue or other glue. The glue with low fluidity can be selected in the embodiment, the gap can be filled with the glue by controlling the amount of the glue and the glue injection speed, the glue overflowing to the outside of the gap is less, and the influence on the assembly of other parts is prevented.

It will be appreciated that the thickness of the part of the protrusion corresponding to the through hole or groove may be increased, i.e. the protrusion comprises a middle part and side parts, and the through hole or groove is arranged in the middle part, and the width of the middle part is larger than the width of the side parts in the direction parallel to the cover plate.
