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 clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Technical purpose of the present invention is to overcome in prior art, and the Pixel arrangement technology of spherical LED display screen exists the unreasonable technical matters that causes image disappearance or pixel waste of arrangement architecture.Provide a kind of and arrange in order, rationally increase and decrease, image are complete and can not cause the Pixel arrangement structure of the spherical LED display screen of pixel waste.
A kind of Pixel arrangement structure of spherical LED display screen, include spherical surface body, pixel quantity in described spherical surface body on parallel successively decreases gradually to sphere the two poles of the earth in the middle of sphere, and on parallel, adjacent its quantity of successively decreasing of two row pixels meets following relational expression: when N/X < A, and X-Y; Wherein N is unit parallel length, and X is pixel quantity, and Y is the pixel quantity reducing, and A is pel spacing value; N/X is predict pixel distance values; Distance on described parallel between pixel is consistent.
Further, when described Y=1, Y is any one pixel on unit parallel; In the time of Y > 1, between the pixel reducing, distance is and the immediate appropriate value of N/Y.
Further, each pixel comprising in Y reduces evenly to take out between two parties a principle.
Further, described A 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 are understood with reference to earth warp and weft, and the distance on warp between each pixel is consistent, and the distance on parallel between pixel is consistent.Wherein pel spacing value A is made as the lower limit of a distance, and in the time that a distance is less than A, between pixels illustrated, density is excessive, need to reduce pixel quantity, and the pixel quantity that X is current layout, successively decreases as radix.In addition, A pel spacing value allows to be set to higher limit, and in the time that a distance exceedes higher limit, the density between pixels illustrated is too small, need to increase the quantity of pixel, meets following relational expression: when N/X > A, and X+1.A pel spacing value can be also a scope value, and such as A is spacing 10mm, permissible error value is for ± 1 being the numerical value of 9mm-11mm scope; In the time that predict pixel distance values is greater than 11mm, X+1; In the time that predict pixel distance values is 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 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 to poles on sphere 101 gradually from sphere middle 100, its quantity of successively decreasing meets following relational expression: when N/X < A, and X-1; Wherein N is unit parallel length.As example: in the time that 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, X need not subtract 1; In the time that unit parallel length N is decremented to 155mm, predict pixel distance values N/X is 9.6875mm, and being less than pel spacing value A is 10mm.Now X-1, i.e. 16-1=15, now predict pixel distance values N/X is 155mm/15=10.333mm.Distance on described parallel between pixel is consistent, and distance is all 10.333mm.Described A is 9mm or 10mm or 11mm; In addition, in the time that the length difference distance between two adjacent two parallels is larger, reduce after 1 pixel, when point distance is still less than the value of setting, continued to successively decrease by principle, until meet.In pixel of the present invention reduces, when described Y=1, Y is any one pixel on parallel; In the time of Y > 1, between the pixel reducing, distance is the immediate appropriate value of N/Y.In conjunction with Fig. 2, to take out a little or relatively between two parties and to take out a little and reduce as far as possible between two parties, each pixel comprising in Y reduces evenly to take out between two parties a principle.In Fig. 2, left side numeral, for picture number minimizing quantity Y, is taken out a quantity, and the right is picture element matrix.
As Fig. 2: the pixel on parallel is 16, and 1 point between evenly drawing between two parties cuts the 8th pixel, and parallel pixel quantity becomes 15;
As Fig. 2: the pixel on parallel is 16, and 2 points between evenly drawing between two parties cut the 4th pixel and the 12nd pixel, and parallel pixel quantity becomes 14;
As Fig. 2: the pixel on parallel is 16, and 3 points between evenly drawing between two parties cut the 3rd pixel and the 8th pixel, the 12nd pixel, and parallel pixel quantity becomes 13;
As Fig. 2: the pixel on the parallel on parallel is 16, and 8 points between evenly drawing between two parties cut the 1st, 3,5,7,9,11,13,15 pixels, and parallel pixel quantity becomes 8;
As Fig. 2: the pixel on the parallel on parallel is 16, and 15 points between evenly drawing between two parties cut the the the the the 1st, 2,3,4,5,6,7 and the 9th, 10,11,12,13,14,15,16 pixel, and parallel pixel quantity becomes 1.
For example: work as Y=3, when N is 160mm, N/Y:160mm/3 is 53.33mm; Getting the immediate appropriate value pixel of spacing distance and 53.33mm takes out a little; The beneficial effect doing is like this image even 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 in the time that a distance is less than A, between pixels illustrated, density is excessive, need 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 in the time that a distance exceedes higher limit, the density between pixels illustrated is too small, need to increase the quantity of pixel, meets following relational expression: when N/X > A, and X+1.A can be also a scope value, such as the A numerical value that is 9mm-11mm; In the time that predict pixel distance values is greater than 11mm, X+1; In the time that 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 equates 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 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 pel spacing value 10% as error amount, and can not cause image to show obvious distortion, pel spacing value exceeds error amount scope, needs to reduce pixel quantity, also takes out a little; Make it to remain on the relative homogeneity in error range between the pixel of parallel and parallel.
The pixel quantity Y of its minimizing, on parallel, reduces evenly to take out between two parties a principle.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 is out of shape along sphere curved-surface natural, 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 is got A value, cuts apart, until be less than pel spacing A value by meridional parts equal portions.
In a word, the present invention, by above-mentioned arrangement architecture, has 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.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
