Abstract: A method of power down control (PDC) for a display device is to be implemented by a processor in a power down controller of the display device. The power down controller includes a main system, a main system power source, and a PDC power source. The method includes the steps of: (A) receiving power from the PDC power source, determining if the main system is to be activated, and proceeding to step (B) if affirmative; (B) turning on the main system power source, and activating the main system; (C) determining if operation in a power down mode is intended, and proceeding to step (D) if affirmative; and (D) turning off the main system power source to operate in the power down mode. Further, a state parameter is stored that allows the main system to be restored to the operating state prior to a power interruption.

Abstract: In a power-saving control module for an electrical appliance that includes a DC power supply and a remote control receiver, a switch component serves to make or break electrical connection between an AC power source and the DC power supply, a diode provides a path for supply of a DC power output from the DC power supply to the remote control receiver when connection between the DC power supply and the AC power source is made, and a rechargeable power source provides DC power to the remote control receiver when connection between the DC power supply and the AC power source is broken. A driver is controlled by the remote control receiver so as to cause the switch component to make or break the electrical connection between the AC power source and the DC power supply.

Abstract: A cold cathode fluorescent lamp (CCFL) assembly includes a pair of CCFLs, and an inverter-type drive circuit. The drive circuit includes a first transformer having a primary winding adapted to be coupled to a power supply module, and a secondary winding with a pair of terminals. The CCFLs are coupled respectively to the terminals of the secondary winding. The drive circuit further includes a push-pull drive circuit coupled to the primary winding of the first transformer, and adapted to be coupled to the power supply module. The push-pull drive circuit excites the primary winding of the first transformer upon receiving power from the power supply module such that power is transferred from the primary winding to the secondary winding, thus activating the CCFLs coupled thereto.

Abstract: In a rotary supporting base, a stationary lower base member has a top surface formed with a ring-supporting region that is confined by an outer periphery concentric with and surrounding an inner periphery, and is formed with an engaging unit on the inner and outer peripheries. A coupling ring plate is disposed at the ring-supporting region, is rotatable relative to the lower base member, and has inner and outer peripheral edges which are in sliding engagement with the engaging unit to retain rotatably the coupling ring plate on the top surface of the lower base member. A rotatable upper base member is disposed on top of the lower base member and is coupled to the coupling ring plate for co-rotation therewith relative to the lower base member. A coupling unit is provided on the coupling ring plate and the upper base member and engages an upright prop of the display device.
