摘要： A tiled display comprises display devices adjacent to one another and each comprising first pixels and second pixels, a first boundary area where longer sides of at least two of the display devices are adjacent to each other, and a second boundary area where shorter sides of at least two of the display devices are adjacent to each other. Each of the first pixels and the second pixels comprises sub-pixels. The first pixels are disposed in the first boundary area such that the sub-pixels of the first pixels are parallel to the longer sides of the display devices. The second pixels are disposed in the second boundary area such that the sub-pixels of the second pixels are parallel to the shorter sides of the display devices.
