ABSTRACT:
An electro-luminescent display comprises a plurality of scanning lines, a plurality of data lines which are arranged to cross the plurality of scanning lines and forming a plurality of pixel regions, at least one indicating driving circuit, and at least one indicating electro-luminescent device. Each of the pixel regions includes a switching circuit, a pixel driving circuit, and a pixel electro-luminescent device having a color type. The switching circuit is electrically connected to a respective one of the scanning lines and a respective one of the data lines. The pixel electro-luminescent devices electrically connected to one of the data lines have the same color type as each other. The indicating driving circuit, distinct from the pixel driving circuits, is electrically connected to the one data line and is controlled by a signal thereon. The indicating electro-luminescent device is electrically connected to and is driven by the indicating driving circuit and having the same color type as the pixel electro-luminescent device electrically connected to the one data line.
