The concrete meaning of invention.
The present invention provides a kind of design method of LED ball shape display screen, as follows：
Some LED display modules are arranged on the surface of spherical fixed mount and form spherical display screen, the LED display modules
Shape and the spherical fixed mount the shape surrounded of parallel and warp it is essentially identical；
Some LEDs are arranged in the LED display modules into array, often the quantity of row LED is identical, each column LED
Quantity is identical；
When the LED display modules change in the width on latitude direction, in LED substantially corresponding with the latitude direction
In lamp row, the spacing between at least one group of adjacent two row LED also changes.
In the method, some LED display modules by splice installed in the spherical fixed mount surface on from
And form spherical display screen.Be provided with some parallels and some warps on the surface of the spherical fixed mount, some parallels it
Between spaced predetermined latitude, spaced predetermined longitude between some warps, some parallels and some warps intersect shape
Into some regions（The shape that parallel and warp surround）.In that region, the shape base in the region on same latitude number
This is identical, and the shape in the region on the different dimensional number of degrees differs.It is it should be noted that spaced pre- between some parallels
The number of degrees for determining latitude can be with identical or differ, i.e., some parallels are uniformly distributed or uneven distribution；Between some warps mutually
The number of degrees of the predetermined longitude at interval can be with identical or differ, and even xeromenia line is uniformly distributed or uneven distribution.
The spherical fixed mount glomeration, some parallels can be provided in the mark on the surface of the spherical fixed mount
Parallel, some warps can be provided in the mark warp on the surface of the spherical fixed mount, mark parallel and mark warp
The surface of the spherical fixed mount is divided into some regions.
Or the spherical fixed mount is made up of some parallel plates and some warp plates, some parallel plates are arranged on some
The inside of warp plate, some warp plates are connected by connector with some parallel plates, or some warp plates and some warp plates
Weld together.Or the spherical fixed mount is made up of some parallel plates and some warp plates, some parallel plates and some
Warp plate, which intersects, to be fastened on together, i.e., some parallel plates and some warp plates are generally within same arcwall face.
The spherical fixed mount is made up of some parallel plates and some warp plates, and some warp plates and some parallel plates can
Using the warp and weft as spherical fixed mount when installing the LED display modules.Or some warp plate conducts
The warp of the spherical fixed mount during LED display modules is installed, the spherical fixed mount during LED display modules is installed
Parallel using mark parallel.Or latitude of some parallel plates as spherical fixed mount when installing the LED display modules
Line, the warp of the spherical fixed mount during LED display modules is installed using mark warp.
In the method, some parallels and some warps intersect to form some regions, and in that region, always
With the presence of the LED display module essentially identical with its shape, i.e., the shape of some LED display modules is substantially and some
The shape in region is essentially identical, and the shape of the LED display modules and the shape that parallel and warp surround are essentially identical.Namely
To say, the shape of four sides of the LED display modules is essentially identical with the parallel in corresponding region and the shape of warp respectively,
The side of left and right two of i.e. described LED display modules is corresponding with the warp in the region respectively, the LED display modules it is upper
Lower two sides are corresponding with the parallel in the region respectively, the side of left and right two of the LED display modules and upper and lower two sides
While respectively along in the region（The spherical fixed mount）Warp and weft set.Pacify by some LED display modules
When on the surface of the spherical fixed mount, it is only necessary to be separately mounted to some LED display modules and its shape phase
On same region.
Always have that the shape in some regions is identical in some regions, these shape identical regions are primarily present those latitudes
Numerical value identical region, such as be located at Same Latitude region, or above and below equator both sides south latitude region and north latitude region.This
Sample also causes, in some LED display modules, there is also the more than two LED display modules of shape identical.
In the method, some parallels and some warps intersect to form some regions, some regions be by warp and
Parallel is formed.With the increase of latitude, the distance between adjacent two warps are less and less, and the length of warp will not become.So
So that on projecting direction, the projection in some regions substantially into isosceles trapezoid, the projection of parallel be isosceles trapezoid upper bottom edge and
Bottom, the projection of warp is two waists of isosceles trapezoid.Isosceles trapezoid is projected into due to some regions so that the LED
For the projection of shape of display module also into isosceles trapezoid, the spherical display screen is into described in isosceles trapezoid as some projection of shape
LED display modules are spliced to form.It should be noted that the LED display modules can be designed to isosceles trapezoid tabular；Or
The LED display modules are designed camber by person, but it projects into isosceles trapezoid.
Due to the distance between the increase of latitude, adjacent two warps it is less and less.Therefore the width of isosceles trapezoid
Relation between latitude is, with the increase of latitude, the distance between two waists of isosceles trapezoid are more and more narrow；Or with
The distance between the reduction of latitude, two waists of isosceles trapezoid is more and more wider.That is, described two waists of LED display modules
The distance between it is more and more narrow with the increase of latitude, or the distance between two waists of the LED display modules are with latitude
Reduction it is more and more wider.Width of the i.e. described LED display modules on latitude direction narrows with the increase of latitude, or described
Width of the LED display modules on latitude direction broadens with the reduction of latitude.
Because the spherical fixed mount is made up of some parallel plates and some warp plates, some warp plates are as installation institutes
The warp of spherical fixed mount during LED display modules is stated, the parallel of the spherical fixed mount during LED display modules is installed
Using mark parallel.So left and right side by the LED display modules（Waist）Along the warp direction of the spherical fixed mount
Set, will the LED display modules left and right side（Waist）On warp plate.
In the method, when the LED display modules change in the width on latitude direction, with the latitude side
Into basic corresponding LED row, the spacing between at least one group of adjacent two row LED also changes.
The LED display modules are into isosceles trapezoid, width of the LED display modules on latitude direction（Between two waists
Distance）Narrow with increaseing or decreasing for latitude or broaden.In LED light array, often the quantity of row LED is identical, often
The quantity of row LED is identical.That is, change regardless of width of the LED display modules on latitude direction, in institute
The line number and columns for stating some LEDs in LED display modules do not change all the time, between the simply adjacent two row LED of change
Spacing, i.e., the change of width of the spacing with the LED display modules on latitude direction between adjacent two row LED and
Change.
When the LED display modules are in the narrowed width on latitude direction or when broadening, then basic with the latitude direction
In corresponding LED row, the spacing between at least one group of adjacent two row LED also narrows or broadened.That is, when described
LED display modules are in the narrowed width on latitude direction or when broadening, then in LED row substantially corresponding with the latitude direction
In, there is the spacing between one group of adjacent two row LED also to narrow or broaden, or between having between multigroup adjacent two row LED
Away from also narrowing or broaden, or all the spacing between adjacent two row LED also narrows or broadened.In the LED display modules
In LED row on the wider position of width, the gap ratio between adjacent two row LED is wider；And show mould in the LED
In LED row on the narrow position of group width, the spacing between at least one group of adjacent two row LED is narrow.Also
It is to say, in the LED display modules, on the wider position of distance between two waists, LED distribution is diluter, described
The pixel ratio of LED display modules is relatively low；In the LED display modules, on the narrow position of distance between two waists,
LED distribution is closeer, and the pixel ratio of the LED display modules is higher.
In the method, directly some LEDs can be arranged in the LED display modules into array, in LED battle array
In row, often the quantity of row LED is identical, and the quantity of each column LED is identical.In every row LED, at least one group of adjacent two row
The change of width of the spacing with the LED display modules on latitude direction between LED and change.For example, by first
Row LED, the second row LED ... Nth row LED（N is the integer more than or equal to 2）It is successively set on from top to bottom described
In LED display modules, the upper width of the LED display modules is less than its underpart width.In the second row LED, Ke Yishi
The distance between first row LED and secondary series LED narrow（Spacing between one group of adjacent two row LED changes）,
And the spacing between other groups of adjacent two row LEDs does not change.In the third line LED, can be secondary series LED and
The distance between 3rd row LED narrows, or/and the distance between the 4th row LED and the 5th row LED narrow, and other
Spacing between the adjacent two row LED of group does not change.
In the method, some lamp bars are provided with the LED display modules, some LEDs are separately positioned on some
In the lamp bar, the LED is arranged on into array at least provided with a row LED, some LEDs in each lamp bar
In display module.The LED display modules also include PCBA board, and some lamp bars are arranged in the PCBA board.
Some lamp bars are set into column-shaped, and the length of some lamp bars is identical, if each lamp bar is only set
It is equipped with a row LED, then the quantity of the LED in every lamp bar is identical and spacing between them is also identical.
In some lamp bars, the spacing between at least one group of adjacent two lamp bar is as the LED display modules are in latitude direction
On width change and change, i.e., when the LED display modules gradually broaden or narrowed in the width on latitude direction, extremely
Spacing between rare one group adjacent two lamp bars also gradually broadens or narrowed.That is, work as in certain a line, first
Spacing between lamp bar described in lamp bar described in bar and Article 2 changes, then lamp described in first lamp bar and Article 2
Spacing between bar from start to finish all changes.It can not say, in a second row, lamp described in first lamp bar and Article 2
Spacing between bar changes, and in the third line, the spacing between lamp bar described in first lamp bar and Article 2 is not
Change, the spacing between lamp bar described in lamp bar described in Article 3 and Article 4 changes.Some lamp bars can also embark on journey
Shape is set, then the length of some lamp bars differs, if each lamp bar is only provided with a row LED, then every
The quantity of LED described in bar in lamp bar is identical and spacing between them differs, the longer lamp bar of length its LED it
Between spacing it is bigger, the spacing between its LED of the shorter lamp bar of length is smaller.
In the method, when some parallels are uniformly distributed, some warps are uniformly distributed.The shape that then parallel and warp surround
To two extreme directions, its size is less and less since equator.That is, latitude is bigger, the chi for the shape that parallel and warp surround
It is very little smaller, while the size of the LED display modules becomes big also with latitude and diminished.The size of the LED display modules is determined
The quantity of fixed LED thereon, the size of the LED display modules is bigger, and the quantity of LED thereon is bigger；The LED shows
Show that the size of module is smaller, the quantity of LED thereon is smaller；Some LED display modules of size identical, thereon
The quantity of LED is identical.
In same longitudinal, the quantity of the LED in the two neighboring LED display modules is different, same
On individual latitude direction, the quantity of the LED in the two neighboring LED display modules is identical.Or in same longitudinal
On, the quantity of the LED in the two neighboring LED display modules is identical or different, on same latitude direction, adjacent two
The quantity phase XOR of LED in the individual LED display modules is identical.During installation, it is only necessary to which the LED display modules are installed
Surrounded in the parallel and warp essentially identical with its shape on position.

The shape in the region on the number of degrees is essentially identical, and the shape in the region on the different dimensional number of degrees differs.It is it should be noted that some
The number of degrees of spaced predetermined latitude can be with identical or differ between parallel 11, i.e., some parallels 11 are uniformly distributed or uneven
Even distribution；The number of degrees of spaced predetermined longitude can be with identical or differ between some warps 12, and even xeromenia line 12 is equal
Even distribution or uneven distribution.
The glomeration of spherical fixed mount 1, some parallels 11 can be provided on the surface of the spherical fixed mount 1
Parallel is identified, some warps 12 can be provided in the mark warp on the surface of the spherical fixed mount 1, identify parallel and mark
Know warp and the surface of the spherical fixed mount 1 is divided into some regions.
Or the spherical fixed mount 1 is by some parallel plates（Do not draw）With some warp plates（Do not draw）Composition, if
Dry parallel plate is arranged on the inside of some warp plates, and some warp plates are connected by connector with some parallel plates, or some
Warp plate is together with some warp plate welds.Or the spherical fixed mount 1 is by some parallel plates and some warp plate groups
Into some parallel plates and some warp plates intersection are fastened on together, i.e., some parallel plates and some warp plates are generally within same
In individual arcwall face.
The spherical fixed mount 1 is made up of some parallel plates and some warp plates, some warp plates and some parallel plates
Can be respectively as the warp 12 and parallel 11 of the spherical fixed mount 1 when installing the LED display modules 2.If or xeromenia
Warp 12 of the line plate as the spherical fixed mount 1 when installing the LED display modules 2, when installing the LED display modules 2
The parallel 11 of the spherical fixed mount 1 is using mark parallel.Or some parallel plates are used as when installing the LED display modules 2
The parallel 11 of the spherical fixed mount 1, the warp 12 of the spherical fixed mount 1 during the LED display modules 2 is installed using mark
Warp.
In the present embodiment, some parallels 11 and some warps 12 intersect to form some regions（Do not draw）, and
In that region, the LED display module 2 essentially identical with its shape always exists, i.e., some LED display modules
2 shape is substantially essentially identical with the shape in some regions, and shape and the parallel 11 and warp 12 of the LED display modules 2 close
The shape enclosed is essentially identical.That is, the shape of four sides of the LED display modules 2 respectively with corresponding region
The shape of parallel 11 and warp 12 is essentially identical, i.e., the sides of left and right two of described LED display modules 2 respectively with the region
The correspondence of warp 12, two sides up and down of the LED display modules 2 are corresponding with the parallel 11 in the region respectively, described
The side of left and right two of LED display modules 2 and upper and lower two sides are respectively along in the region（The spherical fixed mount 1）Warp
Line 12 and parallel 11 are set.When some LED display modules 2 are arranged on the surface of the spherical fixed mount 1, only need
