## Abstract

The present application provides a splicing display, a driving method, and a splicing display device. The splicing display includes first sub-display panels and second sub-display panels. A size and a number of the first sub-display panels are respectively same as a size and a number of the second sub-display panels in horizontal or vertical directions. The first sub-display panel and the second sub-display panel are misaligned by N rows/columns of sub-pixels in the horizontal or vertical directions. Misaligning N rows/columns of the sub-pixels can increase an accuracy of the splicing display, and splicing positions can be prevented from problems of misalignment and blurring.
