Abstract

The spliced display device comprising a plurality of display panels stitched to each other, and each of display panels has display region and non-display region. The spliced display device comprises at least one first display panel and at least one second display panel. An end of first display is backwardly bended away display surface at boundary between display region and non-display region. An end of second display panel is adjacent to first display panel and end of second display panel facing and correspondingly fixed to non-display region of first display panel after been bended. The spliced display device provides at least one non-display region is bended and stitched to other display panel. It closing the distant between the display regions of two adjacent display panels, and achieves to narrow down or even eliminates seam of spliced display device, and improve sense of segmental image vision.
