Problems solved by technology
[0003] 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 an urgent technical problem to be solved by those skilled in the art

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0020] 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 the spherical LED display screen in the prior art. The invention provides a pixel arrangement structure of a spherical LED display screen with orderly arrangement, reasonable increase and decrease, complete image and no waste of pixels. A pixel arrangement structur...

The invention provides a pixel changing method for a spherical surface LED display screen. The interval values of pixels on the adjacent longitude lines of the longitude lines of a spherical surface body are equal, and the interval changing number of lamp points on the latitude lines of the spherical surface body conforms to the following rules that when the quotient of N and X is equal to A, point pulling is not needed; when the quotient of N and X is smaller than A, the quotient of N and X is calculated again after each time of lamp point pulling until the numerical value of the quotient of N and X is approximately equal to the value of A; when the quotient of N and X is larger than A, the quotient of N and X is calculated again after each time of adding a lamp point until the numerical value of the quotient of N and X is approximately equal to the value of A; N is the unit latitude length, X is the pixel number, and A is the pixel interval value. According to the technical scheme, the pixel changing method for the spherical surface LED screen enables images to be displayed evenly, the pixels are arranged reasonably, and waste can be avoided.
Description
[0001] This application is a divisional application of a patent application with the filing date: January 13, 2012, the application number: 201210011890.7, and the title of the invention: a pixel arrangement structure for a spherical LED display. technical field [0002] The invention relates to an LED display screen, in particular to a method for changing pixels of a spherical LED display screen. Background technique [0003] 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 ...
