Abstract

A display apparatus and a method for distributed modules of light-emitting elements, the display apparatus comprising: a plurality of display modules, each comprising: a plurality of total passive clusters, an active control module and an electrical structure module. The total passive clusters and the active control module are attached onto the tube-shaped electrical structure module on one side or both sides. The electrical structure module comprises an interface for data and power transmission between the total passive clusters, the active control module and the electrical structure module such that a display apparatus for distributed modules of light-emitting elements is formed. Since easy assembly, setup, removal, maintenance, re-use, adjustment in display size, excellent display size/weight ratio and both single-sided and double-sided display can be achieved, the display apparatus is suitable for use in temporary display sites. Identical total passive clusters and active control modules can be attached onto different electrical structure modules for various luminance intensities and pitches to fulfill a full-color display. Furthermore, a roll-up mechanism may also be provided so as to unfold or fold the display.
