ABSTRACT:
A planar solid state LCD display for presenting numeric information comprises six generally rectangular arrays of segments arranged in ladder-like disposition with the outermost rectangles being of progressively decreasing height. The segments are selectively energizable to present multiple 7 segment digit displays wherein a digit has maximum height when centered and a reduced height when above or below the centered position. This provides to a viewer a perception which simulates the rotation of rolling of a digit wheel of conventional counter type wherein the trend of rotation is observable.
