Description
Technical field：
The utility model belongs to LED display technical field, is related to a kind of using one or more kinds of basic display moulds
The curved surface LED display screen of block splicing.
Background technology：
Current curved surface LED display screen be all calculated by stringent mathematics, spherical surface (or spherical calotte) is resolved into it is more
These basic display modules are spliced into a seamless curved surface by kind basic display module (triangle or pentagon, hexagon)
LED display.This camber display screen splicing difficulty is big, is difficult to control precision, and the edge joint position of adjacent basic display module
It will appear splicing rib, reflective, optical crosstalk phenomenon easily occur near splicing rib, influence display effect.
Invention content：
The technical problem to be solved by the present invention is to provide one kind capable of reducing splicing difficulty, the easily controlled song of precision
Face LED display.
In order to solve the above-mentioned technical problem, the curved surface LED display screen of the utility model by multiple polygons display module
It is spliced, it is characterised in that adjacent display modules stitching portion has piece；If two adjacent display modules are the first display
Module and the second display module close to the pel spacing of edge joint position are d1 on the first display module, close on the second display module
The pel spacing of edge joint position is d2, and span is d, the first display module between adjacent two nearest pixels between two display modules
With the second display module stitching portion across seam pel spacing d no more than the minimum value in d1 and d2.
Further, the display module shape used in Blending surfaces LED display can it is identical can not also be identical.
The display module includes drive circuit board, at least one piece driving IC and LED light module；Driving IC settings are being driven
The back side of dynamic circuit board, LED luminescence chips are arranged in the front of drive circuit board；Packaging plastic is being covered in drive circuit board just
Face.
Protective film is covered on the packaging plastic.
The side surrounding of the packaging plastic covers dark paint.
The surface of the packaging plastic is plane or curved surface.
The beneficial effects of the utility model：
The utility model breaks being made of a variety of basic modules (triangle or pentagon, hexagon) under traditional sense
Strict, flawless curved surface LED display screen in mathematical meaning, it is purposive bent using the seamed splicing of basic display module
It is difficult to greatly reduce splicing as long as ensureing to be not more than base pixel pitch requirements across seam pel spacing for face LED display
Degree, precision is easy to control, and does not influence display effect；Flexible design can be carried out in edge joint position, such as in the side of packaging plastic
Face surrounding covers dark paint, to avoid optical crosstalk, bright line.
Description of the drawings：
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the curved surface LED display screen partial schematic diagram using the splicing of isosceles triangle display module.
Fig. 2 is the curved surface LED display screen partial schematic diagram using the splicing of isosceles trapezoid display module.
Fig. 3 is adjacent display modules splicing schematic diagram.
Fig. 4 is panel display module structural schematic diagram.
Fig. 5 is convex surface display module structural schematic diagram.
Specific implementation mode：
As shown in Figure 1, the curved surface LED display screen of the utility model is spliced by multiple isosceles triangle display modules 1,
And adjacent display modules stitching portion has piece.
As shown in Fig. 2, the curved surface LED display screen of the utility model is spliced by multiple isosceles trapezoid display modules 2, and
And adjacent display modules stitching portion has piece.
As shown in figure 3, the first display module 31 is adjacent with the second display module 32, stitching portion between the two has piece
4；Pel spacing on first display module 31 at piece 4 is d1, the pixel on the second display module 32 at piece 4
Spacing is d2, d1≤d2, then the first display module 31 is not more than with 32 stitching portion of the second display module across seam pel spacing d
d1。
Display module shape used in Blending surfaces LED display can it is identical can not also be identical, triangle may be used
Shape, quadrangle, the splicing of pentagon or hexagon display module, can also use the display module of two or more shapes to splice.Its
Middle quadrangle can be square, rectangle, trapezoidal.The curved surface LED display screen of splicing can be seamed spherical surface, extrados, inner arc
Face and other curved surfaces.Pel spacing on same display module equal can not also wait.
As shown in figure 4, the display module includes drive circuit board 311, at least one piece driving IC312 and LED light mould
Group 313, three red, green, blue LED chips constitute a LED light module 313；Driving IC312 is arranged in drive circuit board 311
The back side, LED light module 313 are arranged in the front of drive circuit board 311；Packaging plastic 314 is being covered in drive circuit board 311 just
Face has protective film 315 on packaging plastic 314.
As shown in figure 4,314 surface of the packaging plastic is plane, and its side surrounding covers dark paint 316, such as black
Color, dark green, dark blue, brown, dark purple etc..
As shown in figure 5,314 surface of the packaging plastic is convex spherical.
Description forms seamed spherical surface with display module by taking trapezoidal display module as an example.It is wanted first according to the specific of spherical diameter
Seek the basic size for starting to design trapezoidal display module：Upper bottom width, lower bottom width and the height of trapezoidal display module.Similar to build a wall,
It along the circumferential direction spells display module since diametrical position, is within first week one just to set an inversion and spell trapezoidal display module.Second week
Start according to the case where diameter under section and upper diameter determine just setting, the number of upside-down trapezoid display module.Splicing allows
Top, it is following or it is upper have the gap simultaneously below, wanted no more than d1 across seam pel spacing d as long as pel spacing at gap meets
It asks.It is exactly " not having apertured display " in this way for observer.It so " piles up ", constantly adjusts the trapezoidal display mould of each circle
It number of blocks and just sets and inverted ratio.The ball of different-diameter has different display module sizes to be corresponding to it.In spherical top
Portion is not excluded for completing last splicing with another special-shaped module (such as triangle).
