Embodiment Construction

[0028] Such as figure 1 As shown, taking a rectangular display module as an example, the curved LED display screen of the present invention adopts multiple rectangular display modules for splicing. When splicing, there are seams 4 at the splicing of adjacent display modules; The display modules are the first display module 31 and the second display module 32. The pixel pitch on the first display module 31 near the seam 4 is d1, and the pixel pitch on the second display module 32 near the seam 4 is d2. The span between the nearest two adjacent pixels between the display modules is d, and the spanning pixel pitch d at the seam 4 is not greater than the minimum value of d1 or d2.

[0029] Such as figure 2 , 3 As shown, the display module includes a drive circuit board 311, at least one drive IC 312 and an LED lamp module 313; the drive IC 312 is arranged on the back of the drive circuit board 311, and the LED light-emitting chip 313 is arranged on the front of the drive circuit boar...

Abstract

The invention relates to a splicing method of a curved LED display screen. In the method, splicing is carried out by means of a plurality of polygonal display modules; in the splicing process, splicing seams are reserved in the splicing positions of adjacent display modules; two adjacent display modules are set as the first display module and the second display module, the pixel pitch of the position, close to the seam, of the first display module is d1, the pixel pitch of the position, close to the seam, of the second display module is d2, the spacing between two closest adjacent pixel pointsof the two display modules is d, and the seam-across pixel pitch d of the splicing positions of the first display module and the second display module is not larger than the minimum value in d1 and d2. A method for splicing various basic modules into a mathematically tight and seamless curved LED display screen under traditional meanings is broken through, the basic display modules are spliced into the curved LED display screen with seams on purpose, the splicing difficulty is greatly reduced, precision is easily controlled, and the display effect is not affected.

Description

Technical field: [0001] The invention belongs to the technical field of LED display screens, and relates to a curved LED display screen spliced ​​by using one or more basic display modules and a splicing method thereof. Background technique: [0002] The current curved LED display screens are subjected to strict mathematical calculations, decomposing the spherical surface (or part of the spherical surface) into a variety of basic display modules (triangle, trapezoid, pentagon or hexagon), and splicing these basic display modules into one Seamless curved LED display. This kind of curved display screen is difficult to splice, and it is not easy to control the accuracy. In addition, splicing edges will appear at the joints of adjacent basic display modules, and reflections and cross-light phenomena are easy to appear near the splicing edges, which affects the display effect. Summary of the invention: [0003] The technical problem to be solved by the present invention is to provide ...
