Abstract: There are provided an organic light emitting display device, a driving method thereof and a display apparatus. The organic light emitting display device includes an underlay substrate, and organic light emitting pixel units arranged in a matrix on the underlay substrate; wherein the respective organic light emitting units comprise at least two organic light emitting structures which have different light emitting colors, are disposed in cascades and insulated from each other, and a pixel circuit connected corresponding to the organic light emitting structures and configured to drive the organic light emitting structures to emit light. Since the respective organic light emitting pixel units comprise at least two organic light emitting structures which have different light emitting colors, are disposed in cascades, and are insulated from each other, when displaying, each organic light emitting pixel unit can display, in different frame pictures, grey scale effects of at least two colors according to applied signals. The display effect can be raised because each organic light emitting pixel unit can display more colors.
