Abstract: A three-dimensional light-source display device enables light sources to present a three-dimensional display effect in a three-dimensional space. In general, a single light-source display module is used to complete a uniaxial (Y axis) arrangement of light sources, and after the arrangement of a plurality of the light-source display modules is completed, a plurality of the light-source display modules are further arranged to form two-dimensional (X axis and Y axis) and three-dimensional (X axis, Y axis, and Z axis) arrangements. The present invention can further generate a three-dimensional display effect through a circuit design and programmable control.
