Embodiment Construction

[0014] combine figure 1 and figure 2 , which describes the specific implementation of the present invention in detail, but does not limit the claims in any way.

[0015] In the pixel arrangement structure of a spherical LED display screen of the present invention, in the figure, N is the length of the unit latitude, and the number of pixels on the latitude of the spherical body gradually decreases from the middle of the spherical surface 100 to the spherical pole 101, and the decreasing number satisfies the following relationship Formula: When N / X1, the distance between the reduced pixels is the closest appropriate value of N / Y. combine figure 2 , to reduce as much as possible or relatively centered, that is, each pixel contained in Y is reduced by the principle of centered and uniform sampling. figure 2 The number on the left is the number of pixels reduced Y, that is, the number of sampling points, and the right is the pixel matrix.

[0016] As shown in the figure: th...

Abstract

The invention provides a pixel arrangement structure of a spherical LED (light-emitting diode) display screen. The invention technically aims to provide the pixel arrangement structure of the spherical LED display screen, which has the advantages that pixels are orderly arranged and are reasonably increased and decreased; an image is complete; and the waste on the pixels cannot be caused. The pixel arrangement structure comprises a spherical body. The numbers of pixels on parallels on the spherical body are gradually decreased from the middle of the sphere to both poles of the sphere. The decreasing numbers of each two adjacent lines of pixels on the parallels meet the following relation: when N / X is less t than A, X-Y, wherein N represents a unit parallel length; X represents a pixel number; Y represents a reduced pixel number; A represents a pixel spacing value; N / X represents a forecast pixel spacing value; and the distances between the pixels on the parallels are consistent. The pixel spacing A on the adjacent parallels is allowed to have an error of A plus and minus A*10%. The display screen disclosed by the invention is uniform to display the image, cannot cause waste and is applicable to use in the spherical display screen.

Description

technical field [0001] The invention relates to an LED display screen, more specifically, to a pixel arrangement structure of a spherical LED display screen. Background technique [0002] In the existing technology, LED display is more and more widely used in the current technology due to its technical advantages of energy saving and long service life. The number of pixels between them is different, and the pixel arrangement of the spherical LED display in the prior art cannot meet the reasonable pixel arrangement. When the number of light source points is not properly arranged, it will cause the loss of displayed images or the waste caused by excessive image density; Become a technical problem urgently to be solved by those skilled in the art. Contents of the invention [0003] The technical purpose of the present invention is to overcome the technical problem of image loss or pixel waste caused by unreasonable arrangement structure in the pixel arrangement technology of...
