Abstract

The invention discloses a centering pixel extracting method for a spherical LED display screen. According to the method, the distances between adjacent rows of pixels are equal on the same meridian of a spherical body, and pixels on the same parallel are distributed according to the rule that if X/Y=2K, even pixel extraction is conducted to reduce the number of pixels with the K as the sector number, if X/Y=2K+1, centering pixels of X are changed firstly, then pixels are changed evenly with the center pixel as the center of horizontal symmetry and Y-1 as the sector number, wherein X is the number of pixels on the parallel, Y is the number of pixels needing to be changed, K is a natural number, and X,Y and K are all integers. The centering pixel extracting method for the spherical LED display screen is high in universality, suitable for LED spherical display screens in various radii, and capable of increasing the utilization rate of pixel points (lamp beads). Furthermore, pixels are arranged reasonably, waste can not be caused, and energy is saved.

Description

[0001] This application is a divisional application for a patent application with the filing date: January 13, 2012, the application number: 201210011890.7, and the invention title: a spherical LED display pixel arrangement structure. Technical field [0002] The present invention relates to an LED display screen, and more specifically, to a method for centering pixels of a spherical LED display screen. Background technique [0003] In the prior art, LED display screens are more and more widely used in the current technology due to their energy-saving and long service life technical advantages. Spherical LED display screens are in the middle of the sphere to the poles of the sphere due to the particularity of its parabolic shape. The number of pixels is different. The pixel arrangement of the spherical LED display screen in the prior art cannot meet the reasonable pixel arrangement. When the number of light source points is unreasonably arranged, the display image will be missing o...
