Abstract
A splice screen driving method, a splice screen driving device, an electronic device, and computer-readable medium are provided. According to a size of a filling screen in a splice screen, an initial video signal is expanded to obtain a first video signal that drives the filling screen. The second video signal corresponding to the filling screen in the first video signal is sharpened and filtered to improve a clarity of a picture at a connection of a sub-display and the filling screen, to solve a problem of picture blur.
