Abstract: A device for retaining a printed circuit board is provided, which includes a first side plate and two second side plates. The first has at least one first rib perpendicularly protruding therefrom, each of the second side plate has at least one second rib perpendicularly protruding therefrom. The second ribs of the two second side plate are located in a same plane, and the plane that the second ribs of the two second side plates are located is spaced from that the first rib is located. When a printed circuit board (PCB) is placed in the device, the first rib presses against one side surface of the PCB, and the second rib press against the other side surface of the PCB, so that the PCB is retained in the device.
Abstract: In a signal coordinating method and apparatus, a pulse generating circuit receives a VSYNC signal and generates a plurality of critical pulses that define critical time periods from fields can control edges of the VSYNC signal. A determining circuit receives an HSYNC signal and the critical pulses, and generates a trigger signal upon detecting that a line scan control edge of the HSYNC signal appears during one of the critical time periods. A time delay loop introduces a time delay into the VSYNC signal upon receipt of the trigger signal to cause the critical time period to appear after the line scan control edge of the HSYNC signal.
Abstract: A display device includes a display and a stand. The stand serves to support the display, and includes a bracket and a bracket covering. The bracket is mounted on a rear surface of the display, and has a peripheral edge that is formed with a plurality of tabs. The bracket covering includes a frame body that frames a portion of the peripheral edge of the bracket and that is formed with a plurality of pockets, each of which receives a respective one of the tabs of the bracket.
Abstract: A power control unit of a display apparatus includes an AC-to-DC converter for receiving an external AC power. A regulator receives a DC output from the converter, and is operable in one of an enabled state of outputting a target DC power when receiving a first level signal, and a disabled state of not outputting the target DC power when receiving a second level signal. An electronic switch is operable for switching from an OFF-mode, where a processor permits a delay circuit to output the second level signal to the regulator, to an ON-mode, where the electronic switch initially enables the delay circuit to output the first level signal to the regulator such that the processor receives the target DC power from the regulator and where the electronic switch outputs a trigger signal to the processor so as to enable the processor to latch the first level signal and to provide the target DC power to a display module.
Abstract: A method of automatic monitor display adjustments is disclosed. After the monitor is connected to the power and receives a display signal from a computer host, NTAA (No Touch Auto Adjustment) is initiated to automatically adjust the display range and other display settings of the monitor.
Abstract: In a display apparatus, an adjustable supporting device for supporting a display panel includes a support member having a support portion extending inclinedly from a base portion and formed with an upper pivot end opposite to a lower connecting end, which is connected to a rear end of the base portion, in an upright direction, and a pivot unit that includes a pivot plate disposed to confront a coupling member mounted on the display panel, a first pivot member interconnecting pivotally the coupling member and the pivot plate such that the coupling member is rotatable relative to the pivot plate about a first axis, and a second pivot member interconnecting pivotally the pivot plate and the support portion such that the pivot plate is rotatable relative to the support portion about a second axis transverse to the first axis and the upright direction.
Abstract: A stand for a flat panel display, such as an LCD display, includes a base member, a one-piece bracket plate, and a pair of mounting units for mounting pivotally the panel display. The bracket plate includes a planar support member, a front connecting member projecting forwardly from a lower end of the support member, and two bracing members projecting rearwardly from two lateral ends of the support member. Two connecting members project respectively rightward and leftward from lower ends of the bracing members. The front connecting member is secured on the base member. The support member has an upper edge with a length larger than that of the lower end thereof. The bracket plate defines right and left corners at the lateral ends so as to reinforce bending strength thereof.

Abstract: The invention provides a boost circuit including a first capacitor, a transformer, a sensing resistor and a second capacitor. The transformer has a boost side coil with its one end connected in series with the first capacitor. The sensing resistor is connected in series with the other end of the boost side coil of the transformer, and one end of the second capacitor is connected in parallel with the transformer. Also, the invention provides a power supply converter including a boost circuit and a detection circuit. The boost circuit is used to produce a voltage and output a detection signal to detect the occurrence of a spark. The detection circuit is electrically connected with the boost circuit and is used to receive the detection signal output by the boost circuit. When the detection circuit detects the detection signal contains an inrush signal, it determines that a spark is occurring within the boost circuit and outputs a control signal according to the inrush signal.
