The invention relates to a method for splicing a curved LED display screen for a smart television conference. According to the method, a plurality of polygonal display modules are adopted for splicing; in the splicing process, spliced seams are reserved in spliced parts of every two adjacent display modules which serve as a first display module and a second display module, the spacing of pixels, close to the corresponding spliced seams, of each first display module is d1, and the spacing of pixels, close to the corresponding spliced seams, of each second display module is d2; the spacing of the two pixel points, closest to each other, of each first display module and the corresponding second display module is d, and the spacing d of the cross-seam pixels at the spliced parts of each firstdisplay module and the corresponding second display module is not greater than the minimum value of d1 and d2. The method breaks through traditional methods of adopting a plurality of basic modules for splicing rigorous and seamless curved LED display screens with a mathematical meaning, the basic display modules are purposefully adopted for splicing the curved LED display screen, the splicing difficulty is greatly lowered, the precision is controlled easily, and a display effect is not affected.
