ENERGY EFFICIENT POWER SEQUENCER CONTROL CIRCUIT

摘要

An electronic system is described comprising an assembly of a plurality of electronic devices each driven by a local power unit and a power sequencer control circuit for controlling the power on or off operation of the local power units. The electronic devices can be for example display units of a display wall. An advantage of such an assembly, e.g. a tiled display or display wall in accordance with embodiments of the present invention is that a low level or as little energy as possible is dissipated by the local power units such as DC power supplies associated with the electronic devices, e.g. tiles of a display, and the associated "housekeeping" electronics. A further advantage of embodiments of the present invention is a limitation of the inrush current at start-up.
