Abstract: A method and apparatus for driving a tiled display, a server, and a storage medium are provided. The spliced display comprises a first sub-display screen and a second sub-display screen, wherein a filling screen is arranged between the first sub-display screen and the second sub-display screen. By the method, the pictures on the sub-display screens are displayed on the filling screen, and images do not need to be spliced after being displayed on the filling screen and the sub-display screens, so as to improve the accuracy of the images at the filling screen and avoid image dislocation.
