The present disclosure provides a display module, which can be applied to display devices such as computer monitors and televisions.

As shown in <FIG>, in an embodiment of the present disclosure, the display module includes:.

It can be understood that, in this embodiment, the back plate body <NUM> is parallel to the display screen <NUM> (generally, the display screen <NUM> is parallel to the back plate body <NUM>, and the display screen <NUM> can also be slightly inclined to the back plate body <NUM>). The side wall <NUM> is bent relative to the back plate body <NUM>, and the optical film set <NUM> is located between the display screen <NUM> and the back plate body <NUM>.

Without loss of generality, in this embodiment, the display screen <NUM> is a liquid crystal screen. In this embodiment, the back plate body <NUM>, the side wall <NUM> and the connecting rib <NUM> are integrally injection molded. That is to say, the back plate <NUM> is configured as an injection molded part to facilitate batch preparation of the back plate <NUM>. In addition, thermal conductive plastics can be used for the injection molding material to facilitate the heat dissipation of the display module. Ordinary plastics can also be used for the injection molding material. In this case, a cooling fin can be added to the back plate <NUM> to improve heat dissipation efficiency, or a semiconductor chilling fin can be added to cool down the back plate <NUM>. However, the design is not limited to this, in other embodiments, the back plate body <NUM>, the side wall <NUM> and the connecting rib <NUM> can also be integrally die-casted. That is, the back plate <NUM> is configured as a casting, which can also facilitate the batch preparation of the back plate <NUM>. In addition, the casting material usually has good heat dissipation efficiency, which is beneficial to the heat dissipation of the display module.

In this embodiment, the back plate body <NUM> is generally quadrilateral. A plurality of side walls <NUM> are provided, and the plurality of side walls <NUM> generally include a left side wall, a right side wall and a top side wall. A bottom of the back plate body <NUM> is empty, on the one hand, it is used to mount the backlight strip, and on the other hand, a core-pulling opening can be formed at the bottom of the back plate body <NUM>, so that the connecting rib <NUM> can be easily formed by core-pulling. Of course, in other embodiments, the core-pulling opening used to form the connecting rib <NUM> by core-pulling can also be an opening surrounded by the free sides of the connecting rib <NUM> of each of the plurality of side walls <NUM>. In this case, the core-pulling slider needs to retract into the opening, and then leave the mounting space in a direction away from the back plate body <NUM> to complete the core-pulling.

In technical solutions of the present disclosure, the inside surface of the side wall <NUM> of the back plate <NUM> is integrally formed with the connecting rib <NUM> for directly connecting the edge of the inside surface of the display screen <NUM>. In this way, parts such as the middle frame and the front frame can be reduced, thereby reducing the assembly steps of the display module, making the assembly of the display module more convenient, and saving labor costs. On the other hand, it also reduces materials and saves material costs, and there is no need to consider the size fit between the back plate <NUM> and the middle frame and the front frame during the development and preparation of the back plate <NUM>, which makes the product development and preparation easier, and as long as the dimensional accuracy of the back plate <NUM> meets the requirements, the product quality can be guaranteed.

In this embodiment, further, a free end of the side wall <NUM> is higher than the connecting rib <NUM>, therefore the free end of the side wall <NUM> can also provide collision protection for the side of the display screen <NUM>, thereby reducing the probability of the break of the display screen <NUM> due to collisions of the side of the display screen <NUM>. In this embodiment, a free end surface of the side wall <NUM> is higher than an outer surface of the display screen <NUM>. Compared with the technical solution in which the free end surface of the side wall <NUM> is lower than the outer surface of the display screen <NUM>, in the present technical solution, the free end of the side wall <NUM> can completely wrap the side of the display screen <NUM> so as to prevent the side of the display screen <NUM> from being impacted, thereby providing more effective collision protection for the side of the display screen <NUM>. In other embodiments, the free end surface of the side wall <NUM> may be flush with the outer surface of the display screen <NUM>, therefore the free end of the side wall <NUM> can also completely cover the side of the display screen <NUM>. It should be noted that, in this embodiment, the free end of the side wall <NUM> refers to an end of the side wall <NUM> away from the back plate body <NUM>, and the free end surface of the side wall <NUM> refers to the end surface of the side wall <NUM> away from the back plate body <NUM> and away from the back plate body <NUM>.

It should be noted that, in other embodiments of the present disclosure, the outer surface of the connecting rib <NUM> may also be flush with the free end surface of the side wall <NUM>. In this case, the display screen <NUM> is flush with the outer surface of the side wall <NUM>, such that when viewing the display module from the front perspective, the side wall <NUM> of the back plate <NUM> is completely invisible, and only the display screen <NUM> can be seen, thereby realizing a full screen in a strict sense and improving user experience. In some other embodiments, in order to realize a full screen, the display screen <NUM> may also be higher than the outer surface of the side wall <NUM>.

In this embodiment, further, the edge of the inside surface of the display screen <NUM> is adhered to an outer surface of the connecting rib <NUM>. Generally, Double-sided glue <NUM>, adhesive glue, etc. may be used to achieve the bonding between the display screen <NUM> and the connecting rib <NUM>. The fixing manner of bonding is simple, however, this design is not limited to this. In other embodiments, a fixing buckle may be integrally formed on the outer surface of the connecting rib <NUM>, and the fixing buckle restricts the display screen <NUM> from being separated from the connecting rib <NUM>. In this embodiment, a glue storage groove (not shown) is integrally formed on the outer surface of the connecting rib <NUM> to increase the use amount and bonding area of the adhesive glue when bonding with adhesive glue, so as to improve the bonding reliability between the display screen <NUM> and the connecting rib <NUM>. Further, a width of a cross section of the glue storage groove gradually increases in a depth direction. For example, the cross section has a dovetail shape. In this way, after the adhesive glue in the glue storage groove is cured and shaped, a wedge-shaped connection structure is formed between the adhesive glue and the glue storage groove, which can improve the connection strength between the adhesive glue and the display screen <NUM> and make the fixing of the display screen <NUM> more reliable.

As shown in <FIG>, in this embodiment, further, the optical film set <NUM> includes a first film <NUM> adjacent to an inner side of the display screen <NUM>, and an edge of the first film <NUM> is provided with a side protrusion <NUM>; and the outer surface of the connecting rib <NUM> is provided with a mounting sink <NUM> communicating with the mounting space, and the side protrusion <NUM> of the first film <NUM> is clamped into the mounting sink <NUM> to provide positioning and certain support for the first film <NUM>. It can be understood that the mounting sink <NUM> is recessed relative to the outer surface of the connecting rib <NUM>, and penetrates the end surface of the end of the connecting rib <NUM> away from the side wall <NUM> to communicate with the mounting space, and the side protrusion <NUM> can be inserted into the mounting sink <NUM> through the penetrating position. In this embodiment, the mounting sink <NUM> is usually provided on the connecting rib <NUM> of the top side wall. Without loss of generality, the first film <NUM> may be a brightness enhancement film, a diffusion film, or the like. As shown in <FIG>, in this embodiment, the connecting ribs <NUM> of each of the two adjacent side walls <NUM> transition smoothly at the corner of the back plate <NUM> without welding, which saves the process. It should be noted that, on the inner side of the first film <NUM>, the optical film set <NUM> may further include a second film, a third film, etc. having other optical properties.

In this embodiment, generally, a depth of the mounting sink <NUM> on the connecting rib <NUM> is not less than a thickness of the side protrusion <NUM> to avoid the side protrusion <NUM> hindering the installation between the edge of the inside surface of the display screen <NUM> and the connecting rib <NUM>. In some special cases, the thickness of the side protrusion <NUM> can also be allowed to be slightly larger than the depth of the mounting sink <NUM>, as long as the thickness of the side protrusion <NUM> is not greater than the sum of the depth of the mounting sink <NUM> and the thickness of the adhesive layer (double-sided glue <NUM> or adhesive glue).

In this embodiment, further, a hanging hole <NUM> is provided on the side protrusion <NUM>, and a hanging protrusion <NUM> is provided on the mounting sink <NUM>. The side protrusion <NUM> is hooked with the hanging protrusion <NUM> of the mounting member through the hooking hole <NUM>, to conveniently mount the first film <NUM> on the connecting rib <NUM>. However, this design is not limited to this, in other embodiments, the side projection <NUM> of the first film <NUM> may also be bonded to the mounting sink <NUM> of the mounting member <NUM>. In an embodiment, an area of the mounting sink <NUM> on the connecting rib <NUM> is greater than an area of the side protrusion <NUM> on the first film <NUM> to facilitate assembly. Similarly, the hanging hole <NUM> on the side protrusion <NUM> is larger than the hanging protrusion <NUM> on the mounting sink <NUM>.

It should be noted that, in this embodiment, the mounting sink <NUM> and the hanging protrusion <NUM> can be integrally formed when forming the back plate body <NUM> and the side wall <NUM> (that is to say, when the back plate body <NUM> and the side wall <NUM> are formed by injection or casting, the mounting sink <NUM> and the hanging protrusion <NUM> are formed at the same time). The mounting sink <NUM> and the hanging protrusion <NUM> can be integrally formed by milling groove technique on the outer surface of the connecting rib <NUM> after forming the back plate body <NUM> and the side wall <NUM>. That is to say, after the back plate body <NUM> and the side wall <NUM> are formed by injection or casting, the mounting sink <NUM> and the hanging protrusion <NUM> are further milled and processed.

As shown in <FIG>, in this embodiment, the optical film set <NUM> further includes a light guide plate <NUM> provided on the inner side of the display screen <NUM>, a positioning member <NUM> is provided on an inner side of the side wall <NUM>, the positioning member <NUM> is located between the connecting rib <NUM> and the back plate body <NUM>, and an side edge of the light guide plate <NUM> is abutted against the positioning member <NUM> to facilitate the positioning and installation of the light guide plate <NUM>. Without loss of generality, the first film <NUM> is located between the light guide plate <NUM> and the display screen <NUM>. Generally, in order to improve the backlight efficiency, the optical film set <NUM> further includes a reflective sheet <NUM> between the light guide plate <NUM> and the back plate body <NUM>. In this embodiment, generally, the inner sides of the left side wall, the right side wall and the top side wall are all provided with positioning members <NUM> to position the light guide plate <NUM> and avoid the shaking of the light guide plate <NUM>. However, this design is not limited to this. In other embodiments, the positioning member <NUM> can also be provided at two corners away from the bottom edge of the back plate body <NUM>.

In this embodiment, the positioning member <NUM> is mounted on the inside surface of the side wall <NUM>. However, this design is not limited to this. In other embodiments, the positioning member <NUM> can also be mounted on the inside surface of the back plate body <NUM>. Generally, the positioning member <NUM> will be adjacent to the side wall <NUM> at this time.

In this embodiment, further, a portion of the inside surface of the side wall <NUM> located inside the connecting rib <NUM> is located more outside than a portion of the inside surface of the side wall <NUM> located outside the connecting rib <NUM>, such that more space is provided on the side of the connecting rib <NUM> close to the back plate body <NUM> to facilitate the installation of the positioning member <NUM>. In this embodiment, generally, the outer side surface of the side wall <NUM> is arranged in a plane, so that the thickness of the part of the side wall <NUM> located inside the connecting rib <NUM> is smaller than the thickness of the part located outside the connecting rib <NUM>.

In this embodiment, the positioning member <NUM> is adhered to the back plate <NUM>. However, this design is not limited to this. In other embodiments, the positioning member <NUM> can also be detachably mounted on the back plate <NUM> (for example, but not limited to a tight fitting and embedding manner), so as to facilitate the replacement of the positioning member <NUM>.

In this embodiment, further, the positioning member <NUM> includes a first positioning block attached to the inside surface of the side wall <NUM>, and a second positioning block formed by bending and extending from a side of the first positioning block close to the back plate body <NUM>; and a free end of the second positioning block is abutted against the side edge of the light guide plate <NUM>. It can be understood that the first positioning block can provide the positioning member <NUM> with a larger area connected to the inside surface of the side wall <NUM>, thereby making the installation of the positioning member <NUM> on the side wall <NUM> more stable.

Besides, as shown in <FIG>, in this embodiment, a free end of the connecting rib <NUM> is provided with a positioning notch <NUM> at a position corresponding to the positioning member <NUM> to facilitate the fitting and installation of the positioning member <NUM> and the side wall <NUM>, and it is also beneficial to indicate an installation position of the positioning member <NUM>.

Further, in this embodiment, the positioning member <NUM> is configured as an elastic positioning member, that is to say, the positioning member <NUM> has elasticity, so as to avoid the phenomenon that the light guide plate <NUM> and the positioning member are difficult to match due to component tolerances. In an embodiment, the positioning member <NUM> may be configured as a rubber member, a silicone member, or the like. In addition, in order to prevent the positioning member <NUM> from absorbing light and affecting the backlight effect, the positioning member <NUM> can be a white rubber member.

The present disclosure also provides a television including a display module, and the specific structure of the display module refers to the above-mentioned embodiment. Since this television adopts all the technical solutions of all the foregoing embodiments, it has at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be repeated here.
