Diodes made of compounds of gallium (Ga) and arsenic (As), phosphorus (P), nitrogen (N), and indium (In) can radiate visible light when electrons and holes recombine. Therefore, they can be used to make light-emitting diodes, which are used as indicator lights in circuits and instruments, or to form text or digital displays. Gallium arsenide phosphide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitrogen diodes emit blue light.

[0055] A method for splicing a seamless structure of a special-shaped LED display screen, the specific method is as follows:

[0056] A1. Place the card plate 1 on the component that needs to be positioned, and then tighten the screw 400 so that the screw 400 drives the extrusion limit plate 401 to extrude one side of the structure, thereby maintaining the installation stability of the splicing structure.

[0057] A2. The display screen to be spliced ​​is then placed in the slot on the card board 1. When the bottom of the display screen contacts the top of the extrusion plate 203, the display screen squeezes the slide plate 201 on the extrusion block 202, causing the airbag 200 to be squeezed. The gas in the airbag 200 then enters the interior of the airbag plate 204 through the connecting tube 205.

[0058] A3. Then, the laminating plate 207 on the airbag plate 204 is laminated to the bottom of the display screen, thereby reducing the gap between the display screen and the structure during use and increasing the fit between the display screen and the structure.

[0059] A4. When the display screen needs to be limited, loosen the nut 305, then adjust the position of the lower pressure plate 302 on the mounting plate 300, then engage the card slot with the card connection structure on the back of the display screen, and then tighten the nut 305 so that the nut 305 positions the threaded column 304, thereby facilitating the position limiting operation of the lower pressure plate 302, thereby increasing the support of the back of the display screen and improving the ease of use of the structure.

[0060] Working principle: When in use, place the card board 1 on the component that needs to be positioned, then tighten the screw 400, so that the screw 400 drives the extrusion limit plate 401 to extrude one side of the structure, so as to maintain the installation stability of the splicing structure, and then place the display screen that needs to be spliced ​​in the card slot on the card board 1. When the bottom of the display screen contacts the top of the extrusion plate 203, the display screen will squeeze the slide plate 201 on the extrusion block 202, so that after the airbag 200 is squeezed, the gas in the airbag 200 enters the interior of the airbag plate 204 through the connecting tube 205, and then makes the bonding plate 207 on the airbag plate 204 fit with the bottom of the display screen, so that the gap between the display screen and the structure can be reduced during use, and the fit between the display screen and the structure is increased;

[0061] When the display screen needs to be limited, loosen the nut 305, then adjust the position of the lower pressure plate 302 on the mounting plate 300, then engage the card slot with the card connection structure on the back of the display screen, and then tighten the nut 305 so that the nut 305 positions the position of the threaded column 304, thereby facilitating the position limiting operation of the lower pressure plate 302, thereby increasing the support of the back of the display screen and improving the ease of use of the structure.

Place the card plate (1) on the component to be positioned, and then tighten the screw (400) so that the screw (400) drives the extrusion limit plate (401) to perform an extrusion operation on one side of the structure, thereby maintaining the installation stability of the splicing structure; A2. The display screen to be spliced ​​is then placed in the card slot on the card board (1). When the bottom of the display screen contacts the top of the extrusion plate (203), the display screen squeezes the slide plate (201) on the extrusion block (202), so that after the airbag (200) is squeezed, the gas in the airbag (200) enters the interior of the airbag plate (204) through the connecting tube (205); A3. Then, the laminating plate (207) on the airbag plate (204) is laminated with the bottom of the display screen, thereby reducing the gap between the display screen and the structure during use and increasing the fit between the display screen and the structure; A4. When the display screen needs to be limited, the nut (305) is loosened, and then the position of the lower pressure plate (302) on the mounting plate (300) is adjusted, and then the card slot is engaged with the card connection structure on the back of the display screen, and then the nut (305) is tightened, so that the nut (305) positions the threaded column (304), thereby facilitating the position limiting operation of the lower pressure plate (302), thereby increasing the support degree of the back of the display screen and improving the convenience of use of the structure.
