Embodiment
Composition graphs 1 and Fig. 2, describe the specific embodiment of the present invention in detail, but be not limited in any way claim.
In the pixel arrangement structure of a kind of spherical LED display screen of the present invention, in the drawings, N is unit parallel length, and in spherical surface body, the pixel quantity of parallel successively decreases from sphere middle 100 gradually to poles on sphere 101, its quantity of successively decreasing meets following relational expression: during N/X < A, X-1; Wherein N is unit parallel length.As example: when N is 160mm, pixel quantity X value is 16, and N/X is predict 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 length N is decremented to 155mm, predict pixel distance values N/X is 9.6875mm, is less than pel spacing value A and 10mm.Now X-1, i.e. 16-1=15, then now predict pixel distance values N/X is 155mm/15=10.333mm.Distance on described parallel between pixel is consistent, and namely distance is all 10.333mm.Described A is 9mm or 10mm or 11mm; In addition, the length difference between two adjacent two parallels, apart from time larger, after namely decreasing 1 pixel, when point distance is still less than the value of setting, then continues to successively decrease by principle, until meet.In pixel of the present invention reduces, during described Y=1, Y is any one pixel on parallel; As Y > 1, the spacing of the pixel reduced is the immediate appropriate value of N/Y.Composition graphs 2, a little reduces to take out as far as possible between two parties a little or to take out relatively between two parties, and each pixel namely comprised in Y reduces evenly to take out a principle between two parties.In Fig. 2, left side numeral is that picture number reduces quantity Y, and namely take out a quantity, the right is picture element matrix.
As figure: the pixel on parallel is 16,1 point between evenly drawing between two parties, and namely cut the 8th pixel, parallel pixel quantity becomes 15;
As figure: the pixel on parallel is 16,2 points between evenly drawing between two parties, and namely cut the 4th pixel and the 12nd pixel, parallel pixel quantity becomes 14;
As figure: the pixel on parallel is 16,3 points between evenly drawing between two parties, and namely cut the 3rd pixel and the 8th pixel, the 12nd pixel, parallel pixel quantity becomes 13;
As figure: the pixel on the parallel on parallel is 16,8 points between evenly drawing between two parties, and namely cut the 1st, 3,5,7,9,11,13,15 pixel, parallel pixel quantity becomes 8;
As figure: the pixel on the parallel on parallel is 16,15 points between evenly drawing between two parties, and namely cut the 1st, 2,3,4,5,6,7 and the 9th, 10,11,12,13,14,15,16 pixel, parallel pixel quantity becomes 1.
As example: work as Y=3, when N is 160mm, N/Y:160mm/3 is 53.33mm; Get spacing distance and the immediate appropriate value pixel of 53.33mm is taken out a little; The beneficial effect done like this is image uniform transition.For convenience of understanding, the warp of sphere and parallel are understood with reference to earth warp and weft; Distance on warp between each pixel is consistent, and the distance on parallel between pixel is consistent, and wherein A is set to the lower limit of a distance, and when a distance is less than A, between pixels illustrated, density is excessive, needs to reduce pixel quantity; X is the pixel quantity of current arrangements, successively decreases as radix.In addition, A allows to be set to higher limit, and when a distance exceedes higher limit, the density between pixels illustrated is too small, needs the quantity increasing pixel, then meets following relational expression: during N/X > A, X+1.A also can be a scope value, and such as A is the numerical value of 9mm-11mm; When predict pixel distance values is greater than 11mm, X+1; When predict pixel distance values is 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 equal with the spacing of y direction in X direction, makes image indeformable, complete reflection image one-to-one relationship.Because LED display forms at sphere, also corresponding arc deformation is made at warp and parallel, therefore, its pel spacing is in certain visual range, and pel spacing allows certain error, is traditionally arranged to be 10% of pel spacing value as error amount, and image can not be caused to show obvious distortion, pel spacing value exceeds ranges of error values, namely needs to reduce pixel quantity, also namely takes out a little; The relative homogeneity in error range is remained between the pixel making it parallel and parallel.
Its pixel quantity Y reduced, on parallel, reduces evenly to take out a principle between two parties.Because spherical LED display screen arc length on warp and parallel is difficult to ensure positive integer, in spherical LED display screen visual range, image globally curved-surface natural distortion, therefore its pel spacing value A value within the scope of A ± A*10%, and do not affect picture quality.Pel spacing value on warp direction gets A value, by the segmentation of meridional parts equal portions, until be less than pel spacing A value.
In a word, the present invention, by above-mentioned arrangement architecture, solves the Substantial technical problem of spherical LED display screen in arrangement, and thus, the present invention has outstanding substantive distinguishing features and significant technical progress.
