[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] A sealing structure for a large display screen, referring to Figure 1 , including a display screen body 10, the display screen body 10 includes a plurality of neatly arranged single-grain display screens 20. The plurality of single-grain display screens 20 are neatly arranged on a large plate to complete the production of the display screen body 10.

[0026] Reference Figure 2 The single-grain display screen 20 includes a first layer of glass 21 and a second layer of glass 22 that are bonded to each other, and liquid crystal 23 is filled between the first layer of glass 21 and the second layer of glass 22. An annular frame glue area 30 is provided near the periphery of the single-grain display screen 20, and the annular frame glue area 30 is arranged around the single-grain display screen 20. The annular frame glue area 30 is filled with edge sealing glue 31, and the first layer of glass 21 and the second layer of glass 22 are bonded by the edge sealing glue 31 to form a hollow sealed cavity, and the liquid crystal 23 is filled in the sealed cavity to ensure the normal display function of the single-grain display screen 20.

[0027] Reference Figure 3 and Figure 4 A cutting route 40 is arranged on the periphery of the single-grain display screen 20 . The cutting route 40 is arranged around the periphery of the single-grain display screen 20 . The cutting route 40 is located on the periphery of the annular frame glue area 30 . The cutting route 40 is used to facilitate cutting of the single-grain display screen 20 .

[0028] Reference Figure 3 and Figure 4 The display screen body 10 is provided with a groove 50 at a position relative to the cutting route 40. The groove 50 is arranged along the circumferential direction of the cutting route 40, and the cutting route 40 is located in the groove 50. The groove 50 is formed on the display screen body 10 by etching, and the groove 50 is recessed in the surface of the display screen body 10. The size of the groove 50 is larger than the size of the cutting route 40, so that the cutting route 40 can be accommodated in the groove 50.

[0029] Reference Figure 3 and Figure 4The groove 50 is filled with a dispensing structure for reducing glass debris generated during cutting, and the dispensing structure is filled in the groove 50 along the circumferential direction of the groove 50. The dispensing structure is a sealant 60, and the sealant 60 covers the cutting route 40, so that when the single-grain display screen 20 is cut, the cutting knife cuts the single-grain display screen 20 along the cutting route 40, and the debris generated by the cutting will be stuck by the sealant 60 on both sides of the cutting route 40, so as to prevent the glass debris from splashing onto the single-grain display screen 20 and scratching the single-grain display screen 20.

[0030] Further, refer to Figure 3 and Figure 4 The distance between the two outer sides of the sealant 60 and the cutting route 40 is 1 mm-2 mm, so that when the cutting knife cuts along the cutting route 40, the glass fragments generated on the cutting route 40 are stuck by the sealant 60 on both sides.

[0031] Reference Figure 1 The area between two adjacent single-grain display screens 20 is also filled with sealant 60, and the display screen body 10 is provided with sealant 60 filling in the area outside the multiple single-grain display screens 20, so that glass fragments will not splash when cutting is performed on the display screen body 10.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
