Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
The technical purpose of the present invention is to overcome in prior art, and the pixel arrangement technology of spherical LED display screen has row
The unreasonable technical problem causing image disappearance or pixel waste of array structure.There is provided a kind of aligned orderly, rationally increase and decrease, image are complete
Whole and do not result in pixel waste spherical LED display screen pixel arrangement structure.A kind of pixel row of spherical LED display screen
Array structure, includes spherical surface body, and the pixel quantity on parallel in described spherical surface body gradually successively decreases to sphere the two poles of the earth in the middle of sphere,
On parallel, its quantity of successively decreasing of adjacent rows pixel meets following relational expression：During N/X ＜ A, X-Y；Wherein N is unit parallel length, X
For pixel quantity, Y is the pixel quantity reducing, and A is pel spacing value；N/X is prediction pixel distance values；Pixel on described parallel
The distance between consistent.
Further, during described Y=1, Y is any one pixel on unit parallel；As Y ＞ 1, the picture being reduced
Between element, distance is immediate appropriate value with N/Y.
Further, each pixel comprising in Y is reduced with uniform snap shot principle between two parties.
Further, described A is pel spacing value：And allow the error of A ± A*10%.
Further, described pixel is LED/light source.
In the present invention, for convenience of understanding, the warp of sphere and parallel reference ground ball warp parallel are understood, every on warp
The distance between individual pixel is consistent, and on parallel, the distance between pixel is consistent.Wherein pel spacing value A be set to a little away from lower limit
Value, when point is away from during less than A, between pixels illustrated, density is excessive, it is desirable to reduce pixel quantity, and X is the pixel quantity of current arrangements,
Successively decrease as radix.Additionally, A pel spacing value allows to be set to higher limit, when point away from exceed higher limit when, pixels illustrated it
Between density too small, need increase pixel quantity, then meet following relational expression：During N/X ＞ A, X+1.A pel spacing value also may be used
To be a value range, such as A is spacing 10mm it is allowed to error amount is numerical value that ± 1 is 9mm-11mm scope；Work as prediction pixel
When distance values are more than 11mm, X+1；When prediction pixel distance values are less than 9mm, X-1.
In conjunction with Fig. 1 and Fig. 2, describe the specific embodiment of the present invention in detail, but claim is not limited in any way.
In a kind of pixel arrangement structure of spherical LED display screen of the present invention, in figure, N is unit parallel length, ball
On the body of face, the pixel quantity of parallel gradually successively decreases to poles on sphere 101 from sphere middle 100, and its quantity of successively decreasing meets following relation
Formula：During N/X ＜ A, X-1；Wherein N is unit parallel length.As example:When N is for 160mm, pixel quantity X value is 16, and N/X is
Prediction pixel distance values；N/X is 10mm；A is pel spacing value, and A is 10mm；N/X=A, then X need not subtract 1；When unit parallel
When length N is decremented to 155mm, prediction pixel distance values N/X are 9.6875mm, are 10mm less than pel spacing value A.Now X-1,
I.e. 16-1=15, then now prediction pixel distance values N/X are 155mm/15=10.333mm.On described parallel between pixel away from
From consistent, that is, put away from being all 10.333mm.Described A is 9mm or 10mm or 11mm；In addition, the length between two adjacent two parallels
When degree gap is larger, that is, after decreasing 1 pixel, point away from during still less than the value arranging, then is continued to successively decrease by principle, until symbol
Close.In the pixel of the present invention reduces, during described Y=1, Y is any one pixel on parallel；As Y ＞ 1, reduced
Between pixel, distance is the immediate appropriate value of N/Y.In conjunction with Fig. 2, carried out with snap shot as placed in the middle as possible or snap shot relatively placed in the middle
Reduce, each pixel comprising in Y is reduced with uniform snap shot principle between two parties.In Fig. 2, left side numeral is as number reduces
Quantity Y, i.e. snap shot quantity, the right is picture element matrix.
As Fig. 2：Pixel on parallel is 16,1 point between uniformly drawing between two parties, that is, cuts the 8th pixel, parallel pixel count
Quantitative change is 15；
As Fig. 2：Pixel on parallel is 16,2 points between uniformly drawing between two parties, that is, cuts the 4th pixel and the 12nd picture
Element, parallel pixel quantity is changed into 14；
As Fig. 2：Pixel on parallel is 16,3 points between uniformly drawing between two parties, that is, cuts the 3rd pixel and the 8th picture
Element, the 12nd pixel, parallel pixel quantity is changed into 13；
As Fig. 2：The pixel on parallel on parallel is 16,8 points between uniformly drawing between two parties, that is, cut the 1st, 3,5,7,9,
11st, 13,15 pixels, parallel pixel quantity is changed into 8；
As Fig. 2:The pixel on parallel on parallel is 16,15 points between uniformly drawing between two parties, that is, cut the 1st, 2,3,4,
5th, the 6,7 and the 9th, 10,11,12,13,14,15,16 pixels, parallel pixel quantity is changed into 1.
As example：Work as Y=3, when N is 160mm, N/Y：160mm/3 is 53.33mm；Spacing distance is immediate with 53.33mm
One appropriate value pixel snap shot；The beneficial effect of do so is image uniform transition.For convenience of understanding, the warp of sphere and latitude
Line reference ground ball warp parallel is understood；On warp, the distance between each pixel is consistent, the distance between pixel on parallel
Unanimously, wherein A be set to a little away from lower limit, when point away from during less than A, between pixels illustrated, density is excessive, it is desirable to reduce pixel
Quantity；X is the pixel quantity of current arrangements, successively decreases as radix.Additionally, A allows to be set to higher limit, when point is on exceeding
During limit value, the density between pixels illustrated is too small, needs to increase the quantity of pixel, then meets following relational expression：During N/X ＞ A, X+
1.A can also be a value range, and such as A is the numerical value of 9mm-11mm；When prediction pixel distance values are more than 11mm, X+1；When
When prediction pixel distance values are less than 9mm, X-1.Pixel adopts LED/light source.
In common plane LED display, pixel is made up of picture element matrix, and pel spacing is in X direction and y direction
Spacing equal so that image is indeformable, complete reflection image one-to-one relationship.Because LED display forms in sphere,
Warp and parallel also make corresponding arc deformation, and therefore, in certain visual range, pel spacing allows certain its pel spacing
Error, be traditionally arranged to be the 10% of pel spacing value as error amount, without leading to image to show obvious deformation, as
Plain distance values exceed ranges of error values, that is, need to reduce pixel quantity, namely snap shot；It is allowed to protect between parallel and the pixel of parallel
Hold the relative homogeneity in error range.
The pixel quantity Y that it reduces, on parallel, is reduced with uniform snap shot principle between two parties.Because spherical LED display screen exists
It is difficult to ensure that positive integer, in spherical LED display screen visual range, globally curved-surface natural becomes image arc length on warp and parallel
Shape, therefore its pel spacing value A value in the range of A ± A*10%, and do not affect picture quality.Pixel on warp direction
Distance values take A value, by the segmentation of meridional parts equal portions, till less than pel spacing A value.
In a word, the present invention passes through above-mentioned arrangement architecture, solves Substantial technical in arrangement for the spherical LED display screen
Problem, thus, the present invention has prominent substantive distinguishing features and significant technological progress.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
