1. A splice screen driving method, wherein a splice screen comprises a plurality of sub-display screens and at least one filling screen, and wherein the plurality of sub-display screens are disposed at intervals by the at least one filling screen, and wherein the splice screen driving method comprises:
acquiring an initial video signal for driving the splice screen, and adjusting a resolution of the initial video signal according to the at least one filling screen to obtain a first video signal;
determining a second video signal corresponding to the at least one filling screen in the first video signal;
performing sharpening filtering on the second video signal to obtain a third video signal; and
replacing the second video signal with the third video signal to obtain a target video signal, and wherein the target video signal is used to drive the splice screen;
wherein the step of acquiring the initial video signal for driving the splice screen, and adjusting the resolution of the initial video signal according to the at least one filling screen to obtain a first video signal comprises:
acquiring the initial video signal, and adjusting the resolution of the initial video signal by linear interpolation to obtain the second video signal corresponding to the at least one filling screen;
wherein the first video signal comprises the second video signal and the initial video signal;
wherein the step of performing sharpening filtering on the second video signal to obtain the third video signal further comprises:
processing the second video signal by using a preset sharpening filter algorithm to obtain the third video signal; and
wherein the preset sharpening filter algorithm is:
g(x,y)=f(x,y)−c*∇2f(x,y)
wherein the g(x,y) is the third video signal, the f(x,y) is the second video signal, the ∇2 f(x,y) is a preset Laplace operator, and the C is a preset sharpening filter coefficient.
