A display device having vertically interleaved lighting units comprises a base member (10), a rotational member (20) rotatably mounted on the base member (10), and a driving unit housed inside the base and rotational members. Across the cylindrical surface of the rotational member (20), there are at least two appropriately spaced light emitting arrays (211, 212, 213, 214), each containing at least one column of lighting units (210). The lighting units (210) in the columns of a light emitting array are positioned such that they interleave vertically with the lighting units in the columns of immediately adjacent light emitting arrays. Due to persistence of vision, the vertical gaps between the lighting units of a light emitting array appear to be compensated by the lighting units of adjacent light emitting arrays, when the rotational member is rotated. This arrangement aims to improve the vertical resolution of a rotating LED display.
