Visual display systems have wide-ranging applications in training simulators, serving as comprehensive systems that expand the display field of view by seamlessly combining multiple display units. This paper introduces an innovative spherical display system based on LED technology, designed to achieve close-proximity real-image display within a spherical enclosure. Additionally, we propose a channel division method tailored for this novel LED spherical display to enable efficient display driving. To address geometric distortion issues that arise when rendering flat graphics on a spherical surface, we present a geometric correction method specially designed for LED spherical displays, providing a comprehensive explanation of its theoretical principles and correction process. Experimental results demonstrate that with the implementation of our proposed channel division and geometric correction methods, the number of driving channels for the LED spherical display is reduced, image cropping is minimized, and there is no need for image fusion processing. Corrected images exhibit no distortion, and channel alignment remains continuous without any displacement. This method offers a straightforward operation, requires minimal parameter settings, and is easily implementable, providing a solid foundation for the widespread application of LED spherical vision display systems the future.
