Splicing display, driving method, and splicing display device

A splicing display device, comprising a splicing display, wherein the splicing display comprises at least two sub-display panels;

• wherein the at least two sub-display panels comprise at least one first sub-display panel and at least one second sub-display panel, 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 a first direction, the first sub-display panel and the second sub-display panel are spliced in the first direction with a misaligned manner, and the first sub-display panel and the second sub-display panel are misaligned by N rows/columns of sub-pixels;
• wherein the first sub-display panel comprises a first dynamic display region and a first normally black display region, the second sub-display panel comprises a second dynamic display region and a second normally black display region, the sub-pixels in the first dynamic display region and the second dynamic display region one-to-one correspond to each other and their number of rows/columns are same;
• wherein the first normally black display region comprises a first normally black sub-display region without correspondence, and the second normally black display region comprises a third normally black sub-display region without correspondence;
• wherein the first normally black sub-display region comprises N rows/columns of the sub-pixels, the third normally black sub-display region comprises N rows/columns of the sub-pixels, and N is a positive integer,
• wherein the first normally black display region further comprises a second normally black sub-display region, and the second normally black sub-display region and the first normally black sub-display region are respectively connected to two sides of the first dynamic display region;
• the second normally black display region further comprises a fourth normally black sub-display region, the fourth normally black sub-display region is connected between the second dynamic display region and the third normally black sub-display region;
• and
• numbers of rows of the sub-pixels of the fourth normally black sub-display region and the second normally black sub-display region are same, or numbers of columns of the sub-pixels of the fourth normally black sub-display region and the second normally black sub-display region are same.
