A multi-color display unit includes at least a first and second plurality of dot-type light sources, such as LED or small lamps, which are arranged in different geometrical patterns and may be powered in any desired order or combination thereof. Each plurality of dot-type light sources may be of different colors or may include color filters in combination with one-color dot-type light sources to form a multi-color display unit. The geometrical arrangement between those dot-type light sources may include bar-type, and/or circumferences, parallel or intersecting, and a combination with other geometrical patterns.
