Useful technique effect of the present invention is: by above-mentioned arrangement architecture, solved cleverly the reasonable Arrangement of spherical LED display screen matrix; Solved the series of technical that rambling laying out pixel brings, display image of the present invention shows evenly; And arrange rationally between the pixel, can not cause waste; Technical scheme of the present invention is non-obvious carrying out the Design with Rule of sphere when layouting for those skilled in the art; When using, can very reasonably solve spherical surface body pixel quantity problem; Therefore, the present invention is with respect to prior art, designs ingenious and has outstanding substantive distinguishing features and significant progressive.
Description of drawings
Fig. 1 is the theory structure synoptic diagram of one embodiment of the invention.
Fig. 2 is the picture element matrix synoptic diagram that the present invention takes out a principle between two parties, and left side numeral pixel is taken out a quantity (0-15), and pixel is a little taken out in the box indicating of black among the figure.
Embodiment
In conjunction with Fig. 1 and Fig. 2, describe the specific embodiment of the present invention in detail, but claim is not done any restriction.
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 the pixel quantity of parallel 100 successively decreases to poles on sphere 101 in the middle of the sphere gradually on the spherical surface body, its quantity of successively decreasing satisfies following relational expression: during N/X＜A, and X-1; Wherein N is unit parallel length.Such as example: when N was 160mm, pixel quantity X value was 16, and N/X is the predict pixel distance values; N/X is 10mm; A is the pel spacing value, and A is 10mm; N/X=A, then X need not subtract 1; When unit parallel length N was decremented to 155mm, predict pixel distance values N/X was 9.6875mm, and A is 10mm less than the pel spacing value.This moment X-1, i.e. 16-1=15, then this moment, predict pixel distance values N/X was 155mm/15=10.333mm.Distance on the described parallel between the pixel is consistent, and namely distance is 10.333mm all.Described A is 9mm or 10mm or 11mm; In addition, when the length difference between two adjacent two parallels when larger, namely reduced by 1 pixel after, point then continues to successively decrease by principle, until meet apart from still less than the value that arranges the time.In pixel of the present invention reduced, during described Y=1, Y was any one pixel on the parallel; When Y＞1, distance is the immediate appropriate value of N/Y between the pixel that reduces.In conjunction with Fig. 2, to take out as far as possible between two parties a little or to take out a little relatively between two parties and reduce, each pixel that namely comprises among the Y reduces evenly to take out between two parties a principle.Left side numeral reduces quantity Y for the picture number among Fig. 2, namely takes out a quantity, and the right is picture element matrix.
As scheming: the pixel on the parallel is 16, and 1 point between evenly drawing between two parties namely cuts the 8th pixel, and the parallel pixel quantity becomes 15;
As scheming: the pixel on the parallel is 16, and 2 points between evenly drawing between two parties namely cut the 4th pixel and the 12nd pixel, and the parallel pixel quantity becomes 14;
As scheming: the pixel on the parallel is 16, and 3 points between evenly drawing between two parties namely cut the 3rd pixel and the 8th pixel, the 12nd pixel, and the parallel pixel quantity becomes 13;
As scheming: the pixel on the parallel on the parallel is 16, and 8 points between evenly drawing between two parties namely cut the 1st, 3,5,7,9,11,13,15 pixel, and the parallel pixel quantity becomes 8;
As scheming: the pixel on the parallel on the parallel is 16, and 15 points between evenly drawing between two parties namely cut the 1st, 2,3,4,5,6,7 and the 9th, 10,11,12,13,14,15,16 pixel, and the parallel pixel quantity becomes 1.
Such as example: work as Y=3, when N was 160mm, N/Y:160mm/3 was 53.33mm; Getting the immediate appropriate value pixel of spacing distance and 53.33mm takes out a little; The beneficial effect of doing like this is the image even transition.Understand for convenient, the warp of sphere and parallel are understood with reference to earth warp and weft; Distance on the warp between each pixel is consistent, and consistent in the distance between the pixel on the parallel, wherein A is set to the lower limit of a distance, and when a distance during less than A, density is excessive between the pixels illustrated, needs to reduce pixel quantity; X is the pixel quantity of current layout, successively decreases as radix.In addition, A allows to be set to higher limit, and when a distance surpassed higher limit, the density between the pixels illustrated was too small, needs to increase the quantity of pixel, then satisfies following relational expression: during N/X＞A, and X+1.A also can be a scope value, is the numerical value of 9mm-11mm such as A; When predict pixel distance values during greater than 11mm, X+1; When predict pixel distance values during less than 9mm, X-1.Pixel adopts led light source.
In the common plane LED display, pixel is comprised of picture element matrix, and pel spacing equates with the spacing of y direction in X direction, so that image is indeformable, and complete reflection image one-to-one relationship.Because LED display forms at sphere, also make corresponding arc deformation at warp and parallel, therefore, its pel spacing is in certain visual range, and pel spacing allows certain error, be traditionally arranged to be the pel spacing value 10% as error amount, and can not cause image to show obvious distortion, the pel spacing value exceeds the error amount scope, namely needs to reduce pixel quantity, also namely takes out a little; Make it to remain between the pixel of parallel and parallel the relative homogeneity in the error range.
The pixel quantity Y of its minimizing reduces evenly to take out between two parties a principle on parallel.Because spherical LED display screen arc length on warp and parallel is difficult to guarantee positive integer that in spherical LED display screen visual range, image is along the distortion of sphere curved-surface natural, so its pel spacing value A value in A ± A*10% scope, and does not affect picture quality.Pel spacing value on warp direction is got the A value, cuts apart by the meridional parts equal portions, until less than pel spacing A value.
In a word, the present invention solved the substantive technical matters of spherical LED display screen on arranging, thereby the present invention has outstanding substantive distinguishing features and significant technical progress by above-mentioned arrangement architecture.
