Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, the lcd panel splicing module 100 includes a first lcd module 10, a front frame 30 and a second lcd module 20. The first liquid crystal module 10 and the second liquid crystal module 20 are spliced with each other, and the front frame 30 is located between the first liquid crystal module 10 and the second liquid crystal module 20. The first liquid crystal module 10 includes a first back plate 12 and a first panel 11. The second liquid crystal module 20 includes a second back plate 22 and a second face plate 21. The front frame 30 includes a connecting portion 33, a first stopper portion 31, and a second stopper portion 33. The first limiting portion 31 and the second limiting portion 32 are both located at the same end of the connecting portion 33. In the first direction 001, the connection portion 33 is simultaneously in contact with and fixedly connected to the first back plate 12 and the second back plate 22. That is, the first back plate 12, the connection portion 33, and the second back plate 22 are sequentially contacted and fixed along the first direction 001. The first liquid crystal module 10 and the second liquid crystal module 20 are spliced and fixed together. In a second direction 002 perpendicular to the first direction 001, the first back plate 12, the first panel 11 and the first limiting portion 31 are sequentially located on one side of the connecting portion 33, and the second back plate 22, the second panel 21 and the second limiting portion 32 are sequentially located on the other side of the connecting portion 33. That is, the first back plate 12, the first panel 11, and the first position limiting portion 31 are symmetrically disposed on the other side of the second back plate 22, the second panel 21, and the second position limiting portion 32 with respect to the connecting portion 33. The first stopper portion 31 is in contact with the first panel 11, and the first panel 11 is fixed in the first direction 001 by the contact with the first stopper portion 31; the second stopper portion 32 is in contact with the second panel 21, and the second panel 21 is fixed in the first direction 001 by the contact with the second stopper portion 32. The connecting portion 33 is an integral structure, or the connecting portion 33 is at least two plate-shaped structures, and the at least two plate-shaped structures do not overlap in the first direction 001.
In the liquid crystal screen splicing module 100 of the present application, the first limiting portion 31 and the second limiting portion 32 of the front frame 30 respectively contact and fix the first liquid crystal module 10 and the second liquid crystal module 20, so that the first liquid crystal module 10 and the second liquid crystal module 20 share one front frame 30 during splicing, that is, only one connecting portion 33 exists between the first liquid crystal module 10 and the second liquid crystal module 20 and is fixed as a splicing seam. Compared with the existing liquid crystal splicing module, the arrangement has narrower splicing seams. Because the existing liquid crystal splicing module usually adopts the independent front frames between two mutually spliced liquid crystal modules, and then the two independent front frames are spliced together, namely the width of the splicing seam between the two adjacent spliced liquid crystal modules is the sum of the thicknesses of the two independent front frames. The liquid crystal display splicing module 100 has the advantage of narrow splicing seams.
It can be understood that, when this application two arbitrary mutual concatenations of LCD screen concatenation module 100 first LCD module 10 with all adopt between the second LCD module 20 during the setting of preceding frame 30, it is whole LCD screen concatenation module 100 can both possess narrower piece effect, and whole impression can effectively be promoted.
In the embodiment of fig. 2, the front frame 30 extends along a third direction 003 perpendicular to both the first direction 001 and the second direction 002 in the third direction 003. The first position limiting portion 31 and the second position limiting portion 32 completely cover the edge of the first panel 12 and the edge of the second panel 22 in the third direction 003 to provide the maximum pressing force to the first liquid crystal module 10 and the second liquid crystal module 20.
In one embodiment, see fig. 3, the first position-limiting portions 31 and the second position-limiting portions 32 are arranged alternately in the third direction 003 to form first notches 311 and second notches 321. The first notch 311 and the second notch 321 are arranged to save a part of material, and at the same time, the shielding area of the first limiting portion 31 and the second limiting portion 32 to the first panel 11 and the second panel 21 is reduced, so that the display area of the first panel 11 and the second panel 21 is increased. On the other hand, if the contact area of the first stopper portion 31 with respect to the first panel 11 is continuous contact, if the material of the first stopper portion 31 is different from the material of the first panel 11, the difference in thermal expansion coefficient between the first stopper portion 31 and the first panel under the same temperature change is likely to occur. That is, the amount of thermal expansion and contraction deformation of the two is different, and the continuous contact fixing mode is not beneficial to the thermal expansion and contraction deformation, or is described as being not beneficial to the stress release of the first limiting portion 31 or the first panel 11. Thus, the first notch 311 can protect the first stopper 31 and the first panel 11. Similarly, the second notch 321 can also protect the second limiting portion 32 and the second panel 21.
Furthermore, the number of the first position-limiting parts 31 is multiple, and a plurality of the first notches 311 are formed in the multiple first position-limiting parts 31; the second notches 32 are also plural, and the plural second limiting portions 32 form plural second notches 321. The plurality of first notches 311 and the plurality of second notches 321 can achieve a better stress relief effect. Meanwhile, the distribution of the first limiting portions 31 and the second limiting portions 32 in the third direction 003 is also beneficial to the respective contact and fixation of the front frame 30 to the first liquid crystal module 10 and the second liquid crystal module 20, so that the structural rigidity is more stable.
The staggered arrangement of the first limiting portions 31 and the second limiting portions 32 can be described as that at least one second limiting portion 32 is disposed between any two adjacent first limiting portions 31 in the third direction 003. On the contrary, at least one first limiting portion 31 may be disposed between any two adjacent second limiting portions 32. The first notch 311 and the second notch 321 are arranged in a staggered manner, so that the first limiting part 31 and the second limiting part 32 of the front frame 30 are uniformly distributed on two sides of the connecting part 33, the structure is more reasonable, and the rigidity is higher.
It can be understood that, when one of the second notches 321 is disposed between two adjacent first notches 311 and one of the first notches 311 is disposed between two adjacent second notches 321, the first notches 311 and the second notches 321 are staggered one by one in the third direction 003. In such a configuration, the first notch 311 and the second stopper portion 32 may be disposed on both sides of the connecting portion 33, and the second notch 321 and the first stopper portion 31 may also be disposed on both sides of the connecting portion 33. That is, the first position-limiting portions 31 and the second position-limiting portions 32 are arranged in a one-to-one staggered manner in the third direction 003. Thus, the projection of the first limiting part 31 on the plane of the connecting part 33 is not overlapped with the projection of the second limiting part 32 on the plane of the connecting part 33. The material saving is facilitated, and a plurality of sections of material can be divided at one end of the connecting portion 33, wherein one section of the material is bent toward one end of the first liquid crystal module 10 to form the first position-limiting portion 31, and the other section of the material is bent toward one end of the second liquid crystal module 20 to form the second position-limiting portion 32. The front frame 30 is made of one piece of material, which can save cost and simplify the assembly process.
In other embodiments, referring to fig. 3, in order to enhance the rigidity between the first position-limiting portion 31 and the second position-limiting portion 32, the first position-limiting portion 31 and the second position-limiting portion 32 may be sequentially connected. That is, in the third direction 003, the projection of the first stopper portion 31 completely covers the second notch 321, and the projection of the second stopper portion 32 completely covers the first notch 311. That is, the projection of the first position-limiting portion 31 on the connecting portion 33 and the projection of the second position-limiting portion 32 on the third direction 003 both have an intersection that coincides with each other. Thus, the first position-limiting portion 31 and the second position-limiting portion 32 are connected to each other, so that the rigidity is improved and the deformation is prevented.
For the embodiment that the connecting portion 33 has at least two plate-like structures, referring to fig. 4, the front frame 30 is divided into a first front frame 301 for positioning the first liquid crystal module 10 and a second front frame 302 for positioning the second liquid crystal module 20. The first front frame 301 is provided with a first connecting portion 331 and the first limiting portion 31, and the second front frame 302 is provided with a second connecting portion 332 and the second limiting portion 32. The first connecting portion 331 and the second connecting portion 332 are sequentially arranged in a non-overlapping manner along the third direction 003 to form the connecting portion 33, so that the arrangement of the first limiting portion 31 and the second limiting portion 32 can be more flexibly realized. The first front frame 301 is disposed at a position where the first liquid crystal module 10 needs to be contacted and fixed, and the second front frame 302 is disposed at a position where the second liquid crystal module 20 needs to be contacted and fixed, so that a better implementation effect can be achieved for some specially-shaped liquid crystal screen splicing modules 100. That is, when the lengths of the edges where the first liquid crystal module 10 and the second liquid crystal module 20 are spliced with each other in the third direction 003 are different, the flexible arrangement between the first front frame 301 and the second front frame 302 can respectively realize a better fixing effect on the first liquid crystal module 10 and the second liquid crystal module 20.
In some embodiments, the connection between the first liquid crystal module 10 and the second liquid crystal module 20 and the front frame 30 is implemented by using a bolt 41 and a positioning member 42. Referring to fig. 1, the bolts 41 simultaneously penetrate through the first back plate 12, the connecting portion 33 and the second back plate 22, so that the first liquid crystal module 10, the front frame 30 and the second liquid crystal module 20 are sequentially connected in the first direction 001. The positioning member 42, like the bolt 41, also penetrates through the first back plate 12, the connecting portion 33 and the second back plate 22, and the positioning member 42 is used for ensuring the relative position between the first liquid crystal module 10 and the second liquid crystal module 20. Specifically, the first liquid crystal module 10 and the second liquid crystal module 20 are located at opposite positions in the second direction 002. On the other hand, the positioning member 42 can also ensure that the front frame 30 effectively contacts the first panel 11 and the second panel 21, so as to achieve a fixing effect. That is, the positioning member 42 can simultaneously ensure the contact and fixation of the first position-limiting portion 31 and the first panel 11, and the contact and fixation of the second position-limiting portion 32 and the second panel 21.
In still other embodiments, the lcd panel splicing module 100 includes a positioning bolt 43, the positioning bolt 43 simultaneously penetrates through the first back plate 12, the connecting portion 33 and the second back plate 22 to connect the first lcd module 10, the front frame 30 and the second lcd module 20 in the first direction 001, and the positioning bolt 43 further positions the first lcd module 10, the front frame 30 and the second lcd module 20 in the second direction 002. It is understood that the positioning bolt 43 should include a positioning section 431 and a threaded section 432, and the positioning section 431 passes through the first back plate 12, the connecting portion 33 and the second back plate 22 for positioning therebetween. The threaded end 432 passes through the first back plate 43, the connecting portion 33 and the second back plate 22 before the positioning section 431, so as to achieve the connection function of the three.
In some embodiments, in order to eliminate the phenomenon of stress concentration, the boundary position between the connecting portion 33 and the first position-limiting portion 31 or the second position-limiting portion 32 is configured to be in fillet transition, so that cracks between the first position-limiting portion 31 and the connecting portion 33 or between the second position-limiting portion 32 and the connecting portion 33 due to stress concentration can be avoided, and the service life of the lcd panel splicing module 100 is prolonged.
The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
