摘要： The present invention sufficiently reduces unwanted radiation in a plasma display panel (PDP) display device. The display device includes a PDP having a pair of electrodes, a first, a second, and a third conductive member, and a pair of driving circuits used to apply a voltage to their respective electrodes. Each conductive member has substantially the same width and height as the PDP, and the first, second, third conductive members are disposed on the rear surface of the PDP, in this order on the rear side of the PDP. The PDP and the conductive members are connected electrically to one another in the end portions of these elements, either directly or via the driving circuits, so that the direction of the current flowing in the PDP during driving and discharge coincides with the direction of the current flowing in the third conductive member, and is opposite from the direction of the current flowing in the first conductive member and the second conductive member.

摘要： The present invention provides a shield structure for an electronic device allowing conductive members to be connected electrically to each other at low impedance while preventing the leakage of electromagnetic waves effectively. The first conductive member and the second conductive member for enclosing the electronic device respectively have laid portions that are laid one on the other and fastened to each other at plural positions by means of screw members. Through-holes into which the screw members are to be inserted are formed on both of the laid portions. Protruding portions, which protrude toward the laid portion of the second conductive member, each are formed between the adjacent through-holes on the laid portion of the first conductive member. The protruding portions each have a shape extending in the direction connecting the adjacent through-holes and bulging from both ends toward the center thereof in a smooth curve.

摘要： A voltage memory stores a signal level of a transmission signal from a signal generator at a timing of a clock signal, and outputs the transmission signal. A voltage difference detector detects a signal level of a transmission signal at a timing subsequent to the timing and detects a first signal level difference between the signal level and the signal level from the voltage memory. A maximum value detector, a voltage difference detector and bias voltage sources delay the transmission signal so as to keep a rise time of the transmission signal substantially within a predetermined value range by adding capacitances corresponding to the first signal level differences from the voltage difference detectors to transmission lines.
