As shown in
In an exemplary embodiment, in order to enable the liquid crystal display component to emit light normally for display, a relative positional relation between the liquid crystal panel 2, the back plate 3 and the backlight component 4 in the liquid crystal display component is known to those skilled in the art, that is, an order of the above-mentioned liquid crystal panel 2, the backlight component 4 and the back plate 3 may be in a stacked arrangement. The backlight component 4 may include an optical film 41, a diffusion plate 42, a reflection plate 43, and lamp beads embedded in the reflection plate 43 which are sequentially arranged in a stacked manner, wherein light from the lamp beads is directed to the diffusion plate 42.
In an exemplary embodiment, the supporting frame 1 is a frame forming a ring, which may be a rectangular ring or a circular ring. The supporting frame 1 is used for mounting and fixing the liquid crystal panel 2, the back plate 3 and the backlight component 4, and is used for maintaining the relative positional relation between the liquid crystal panel 2, the back plate 3 and the backlight component 4, and for forming a relatively sealed space together with the liquid crystal panel 2 and the back plate 3. That is, the supporting frame 1 closes around an accommodation space formed between the liquid crystal panel 2 and the back plate 3 to form the sealed space, so that in the accommodation space the backlight component 4 may avoid intrusion of the dust, thus preventing entering dust from affecting the display effect. The frame body 11 of the supporting frame 1 is a supporting body surrounding around the back plate 3, wherein a cross-section of the frame body may be strip-shaped or may be designed according to the structural requirements of products. The frame body 11 of the supporting frame 1 and the supporting platform 12 may be integrally formed, for example, integrally formed by injection molding or extrusion. The cross-sectional shape of the supporting platform 12 is not limited, as long as the supporting platform 12 has a supporting surface capable of supporting the liquid crystal panel 2. The supporting surface may be a flat surface and have a certain angle with respect to the liquid crystal display panel, or may be a supporting surface with a colloid groove. As for the colloid layer 6 between the supporting platform 12 and the liquid crystal panel 2, the colloid layer 6 may be formed by dispensing glue on the supporting surface of the supporting platform 12 in advance by a dispensing process, and then the liquid crystal panel 2 is overlapped onto the supporting surface to make it contact with the colloid layer 6 to realize a gluing connection. A connection between the first end of the frame body 11 and the back plate 3 may be a clamping connection or a gluing connection. In order to ensure performance of convenient assembly, the frame body 11 and the back plate 3 may be in transition fit.
In the liquid crystal display component according to the embodiment of the present disclosure, the first end of the frame body 11 of the supporting frame 1 surrounds around the back plate 3 and is connected with the back plate 3, and the supporting platform 12 is convexly arranged at the second end of the frame body 11 and the supporting platform 12 is connected with the liquid crystal panel 2 by arranging the colloid layer 6. As shown in
In an exemplary embodiment, the narrowest width of the foam glue needs to be greater than or equal to 1.2 mm due to requirements of manufacturing processes of the foam glue and adhering of the foam glue. Therefore, if the liquid crystal panel 2 and the supporting frame 1 are connected with each other using the foam glue, the supporting platform 12 of the supporting frame 1 cannot be made narrower, that is, the effect of narrow bezel cannot be achieved. In the embodiment of the present disclosure, the supporting frame 1 and the liquid crystal panel 2 are connected with each other using the colloid layer 6, since the colloid layer may be formed narrower, the width of the supporting platform 12 from one side close to the middle part of the supporting frame 1 to the frame body 11 is provided to be greater than or equal to 0.5 mm and less than 1.2 mm in the embodiment of the present disclosure. Compared with use of the foam glue, the use of the colloid layer 6 in the embodiment of the present disclosure can achieve the effect of narrow bezel.
In an exemplary embodiment, a distance between the supporting surface of the supporting platform 12 and the second end of the frame body 11 is equal to a thickness of the liquid crystal panel 2.
In an exemplary embodiment, a step is formed between the supporting platform 12 and the second end of the frame body 11, wherein a height of the step is equal to the thickness of the liquid crystal panel 2. In this way, when the liquid crystal panel 2 is overlapped and bonded on the supporting platform 12, the liquid crystal panel 2 is flush with the second end of the frame body 11, and the formed liquid crystal display component has a flush light exiting surface for display, which is convenient for subsequent work such as closing the cover plate or packaging.
In an exemplary embodiment, the liquid crystal panel 2 is connected with the supporting surface of the supporting platform 12 with glue, and the glue needs to be dispensed on the supporting surface of the supporting platform 12 in advance during the production process. Therefore, in order to prevent the glue from flowing out from the supporting surface of the supporting platform 12, an included angle R between the supporting surface of the supporting platform 12 and the liquid crystal panel 2 may be set to be greater than 0 degree and less than or equal to 50 degrees, that is, the supporting surface of the supporting platform 12 inclines towards the frame body 11 by the above angle. The angle R between the supporting surface of the supporting platform 12 and the liquid crystal panel 2 may be greater than 0 degree and less than or equal to 10 degrees.
In an exemplary embodiment, a first groove 13 is arranged on one side of the supporting surface at a joint between the supporting platform 12 and the frame body 11, and the first groove is used for accommodating colloid 5 for bonding the liquid crystal panel 2.
In an exemplary embodiment, as mentioned above, it is necessary to dispense glue on the supporting surface of the supporting platform 12 in advance before bonding the liquid crystal panel 2 and the supporting platform 12. Therefore, in order to better ensure that the glue will not overflow, the first groove 13 may be arranged on one side of the supporting surface at the joint between the supporting platform 12 and the frame body 11. The first groove 13 is a glue overflow groove, wherein a shape of the first groove 13 may be arc-shaped.
In an exemplary embodiment, the colloid 5 is filled between the liquid crystal panel 2 and the frame body 11.
In an exemplary embodiment, by arranging the colloid layer 6 between the liquid crystal panel 2 and the supporting surface of the supporting platform 12, and arranging the colloid between the liquid crystal panel 2 and the frame body 11 as well, the liquid crystal panel 2 may be effectively fixed and the adhesive strength may be effectively increased. The colloid layer 6 arranged between the liquid crystal panel 2 and the supporting surface of the supporting platform 12 may be formed after a first time of dispensing. The colloid may also be arranged between the liquid crystal panel 2 and the frame body 11. After the first time of dispensing, a second time of dispensing may be performed between the liquid crystal panel 2 and the frame body 11 after the liquid crystal panel 2 is overlapped on the supporting surface and bonded with the colloid layer 6 after the first time of dispensing.
In an exemplary embodiment, a second groove 14 is arranged on one side opposite to the supporting surface at the joint between the supporting platform 12 and the frame body 11 .
In an exemplary embodiment, the frame body 11 and the back plate 3 may be in transition fit, so the arrangement of the second groove 14 may disperse the stress caused by interference fit, wherein the second groove 14 may be an arc groove or a rounded corner concaved toward the joint between the frame body 11 and the supporting platform 12.
In an exemplary embodiment, a clamping part 15 protrudes from the side opposite to the supporting surface of the supporting platform 12 toward the first end of the frame body 11. A first clamping part 16 is arranged at the first end of the frame body 11 toward the middle part of the supporting frame 1. A second clamping part 31 is arranged at the back plate 3. The first clamping part 16 is clamped with the second clamping part 31. An end of the back plate 3 is limited between the frame body 11 and the clamping part 15.
In an exemplary embodiment, due to the clamping between the back plate 3 and the frame body 11, space formed between the clamping part 15 and the frame body 11 may allow the end of the back plate 3 to extend therein. At this time, the clamping part 15 may limit the back plate 3 to a certain extent, so that the back plate 3 and the frame body 11 may be clamped with each other stably. The first clamping part 16 may be a clamping groove, and the second clamping part 31 may be a clamping block. Optionally, the first clamping part 16 and the second clamping part 31 may be interchanged, as long as it is ensured that the first clamping part 16 may be stably clamped with the second clamping part 31.
In an exemplary embodiment, the supporting frame 1 is in shape of a rectangular ring. As shown in
In an exemplary embodiment, because rectangular liquid crystal display components are commonly used, when the liquid crystal display component is rectangular, it is necessary to correspondingly provide the supporting frame 1 to be in shape of a rectangular ring. At this time, the four side frames of the supporting frame 1 may be formed by two parts or four parts. When the supporting frame 1 is formed by two parts, as mentioned above, the first part includes frames with three adjacent sides and is a U-shaped frame as a whole, and the second part is a line-shaped frame. At this time, the structure of the three frames of the first part may be completely the same as the structure of the second part, or the extension length of the supporting platform 12 of the line-shaped frame of the second part may be set to be relatively longer. So that the U-shaped frame of the first part may respectively correspond to three sides of the liquid crystal panel 2 where no driving circuit is arranged, while the line-shaped frame of the second part corresponds to one side of the liquid crystal panel 2 where a driving circuit is arranged. Similarly, when the supporting frame 1 is formed by four parts, all the four parts are line-shaped frames which may have the same structure. Or, as mentioned above, the three adjacent line-shaped frames have the same structure and correspond to the three sides of the liquid crystal panel 2 where no driving circuit is arranged, and an extension length of the supporting platform 12 of the other line-shaped frame is greater than an extension length of the supporting platform 12 of the other three line-shaped frames, and the line-shaped frame corresponds to the side of the liquid crystal panel 2 where the driving circuit is arranged.
As shown in
In an exemplary embodiment, since the supporting platform 12 of the liquid crystal display component according to the embodiment of the present disclosure is bonded with the liquid crystal panel 2, an extension length of the supporting platform 12 is short, that is, the liquid crystal display component has a narrow bezel. At this time, it is necessary to ensure that a gap between the optical film 41 and the back plate 3 is located within a range of the orthographic projection of the narrow bezel. Therefore, a lug 411 having a hitch through hole is arranged at an edge of the optical film 41 and hitched to the bump 32 at the end of the back plate 3. A certain tensile force may be generated in a process of forming and shrinking the optical film 41, so as to avoid a large gap between the optical film 41 and the back plate 3, and further ensure that light emitted by the backlight component 4 will generate no black edge on the edges of the liquid crystal display component.
In an exemplary embodiment, the first end of the frame body 11 is located on one side close to the middle part of the supporting frame, and a guide angle 111 is arranged from the first end of the frame body 11 to the second end of the frame body 11.
In an exemplary embodiment, an angle of the guide angle 111 may be, for example, 15 degrees. The arrangement of the guide angle 111 may facilitate the connection between the back plate 3 and the supporting frame 1, that is, when the back plate 3 is matched with the supporting frame 1, the guide angle 111 may serve a function of guiding the back plate 3.
Another embodiment of the present disclosure provides a liquid crystal display apparatus, which includes a liquid crystal display component as shown in
In an exemplary embodiment, the liquid crystal display component may directly use the liquid crystal display component according to the above-mentioned embodiment, and the implementation structure of the liquid crystal display component may be referred to the related contents described in the above-mentioned embodiment, which will not be repeated here.
In the liquid crystal display component according to the embodiment of the present disclosure, the first end of the frame body 11 of the supporting frame 1 surrounds around the back plate 3 and is connected with the back plate 3, the supporting platform 12 is convexly arranged at the second end of the frame body 11, and the supporting platform 12 is connected with the liquid crystal panel 2 by arranging the colloid layer 6. Compared with what is shown in
Another embodiment of the present disclosure provides a method for manufacturing a liquid crystal display component, which is used for manufacturing the liquid crystal display component according to the above embodiment, and includes steps 301-304 as shown in
Step 301 includes: positioning a supporting frame by using a mold, and performing a first time of dispensing on a supporting platform at a first end of the supporting frame.
In an exemplary embodiment, a mold 7 is used for positioning the supporting frame, which is arranged by a skilled person according to the structure of the supporting frame. For example, as shown in
Step 302 includes: buckling the liquid crystal panel on the supporting platform and bonding the liquid crystal panel with the supporting platform.
In an exemplary embodiment, this process may be completed by an automated machine. For example, a robot or an automated arm holds the liquid crystal panel by suction, buckles the liquid crystal panel onto the supporting platform, and bonds the liquid crystal panel with the colloid layer.
Step 303 includes: performing a second time of dispensing between the liquid crystal panel and a frame body of the supporting frame.
In an exemplary embodiment, as shown in
Step 304 includes: arranging a backlight component on a back plate, and connecting the back plate with a second end of the supporting frame.
In an exemplary embodiment, a structure after the back plate is finally installed is shown in
For the above manufacturing method, the second time of dispensing and the connection between the back plate and the supporting frame may be exchanged in sequence, which will not affect the finished product quality of the liquid crystal display component.
In an exemplary embodiment, the supporting frame may be configured in the form of a four-part supporting frame as described in the above embodiment. As shown in
In summary, in the liquid crystal display component according to the embodiment of the disclosure, the first end of the frame body of the supporting frame surrounds around the back plate and is connected with the back plate, the second end of the frame body is convexly arranged at the supporting platform, and the supporting platform is connected with the liquid crystal panel by arranging the colloid layer. Compared with the prior art, in which the liquid crystal panel is connected with the supporting frame by foam glue, because the foam glue is too narrow, the adhesive strength of the foam glue is insufficient to bond the liquid crystal panel and the supporting frame stably. If the foam glue is too narrow, it is difficult to grasp, which makes it difficult to perform the operation of sticking the foam glue on the supporting frame, and automation cannot be achieved. Manual sticking of the too narrow foam glue cannot be performed. Furthermore, the cutting of the foam glue in a width direction has a certain tolerance, so that it is impossible to bond the liquid crystal panel and the supporting frame by using the narrow foam glue, and it is necessary to use foam glue with a certain width and match the width of the supporting part of the supporting frame with the width of the foam glue. In addition, in order to limit the foam glue and prevent the foam glue from extending into a middle part direction of the supporting frame to block the display area of the liquid panel when the foam glue is stuck with the supporting part of the supporting frame, it is necessary to arrange the groove for limiting the foam glue in the supporting part of the supporting frame. However, the width of the supporting part cannot be equal to or less than the width of the groove due to arrangement of the groove. The width of the supporting part needs to be greater than the width of the foam glue, which in summary causes the supporting part of the supporting frame to extend too far into the orthographic projection area of the liquid crystal panel, that is, a narrow bezel cannot be achieved. In the embodiment of the present disclosure, the supporting frame and the liquid crystal panel are bonded by using the colloid layer. Since the colloid layer may be formed by dispensing, the width of the colloid layer may be accurately controlled by controlling amount of glue dispensed through a dispensing machine. The adhesive strength between the liquid crystal panel and the supporting frame may be met by a narrow colloid layer, so the colloid layer may be provided to be narrower than the foam glue. In addition, the colloid layer may be directly formed by gluing on the supporting surface of the supporting platform without arranging the groove on the supporting platform of the supporting frame. Further, the supporting platform may be made narrower by bonding the liquid crystal panel and the supporting frame using the colloid layer, that is, a distance by which the supporting platform extends toward the middle part of the supporting frame is small, and a distance by which the supporting platform extends into the orthographic projection area of the liquid crystal panel is small, thus making the contact width between the liquid crystal panel and the supporting platform small and the effect of narrow bezel of the liquid crystal display component is achieved.
It may be understood that the relevant features in the above devices may be referred to each other. In addition, “first”, “second”, etc. in the above embodiments are used to distinguish embodiments, and do not represent the advantages and disadvantages of the embodiments.
In the specification provided herein, a great number of details are described. However, it may be understood that embodiments of the present disclosure may be practiced without these details. In some instances, well-known structures and techniques have not been shown in detail so as not to obscure the understanding of this specification.
The above is only the specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited to this. Any person familiar with this technical field may easily conceive changes or substitutions within the technical scope disclosed in the present disclosure, which should be covered within the protection scope of the present disclosure.
