The united display segment elements have common vertical segments. Greater freedom for representing the characters while requiring the smallest possible number of segments is obtained by such a construction. In addition, gaps between character representation can be minimized or eliminated, allowing characters to be represented in a centered arrangement with a regular spacing.
