摘要： A plasma display device has a pair of substrates having electrodes and terminals provided at ends of the electrodes. Driving circuits supply a driving voltage to the electrodes via flexible printed circuit boards to emit light. Connectors are detachably attached to the substrate. The connector includes a housing and terminal members disposed in the housing, with the terminal member having a U-shaped cross-sectional shape, so that a first portion as one leg of the “U” contacts the terminal of the electrode and a second portion as another leg of the “U” contacts the conductor of the flexible connecting member. The terminals of the electrodes are arranged in a staggered manner at the end of the substrate.

摘要： An electrode drive circuit performs interlaced scanning, ensuring that the phases of the sustaining pulse in odd-numbered lines and even-numbered lines among L1 to L8 between surface discharge electrodes are the reverse of each other. With this, when either odd-numbered lines or even-numbered lines are displayed, the voltages applied between the electrodes of the undisplayed lines are at 0, eliminating the necessity for partitioning walls on the surface discharge electrodes. In surface discharge electrodes, X electrodes are provided on the two sides of a Y electrode and the area between the Y electrode and the X electrode on one side is assigned a display line at an odd-numbered frame, and the area between the Y electrode and the X electrode on the other side is assigned a display line in an even-numbered frame. Alternate areas between the surface discharge electrodes are assigned as blind lines and a discharge light emission in the blind lines is blocked or incident light to the blind lines from the outside is absorbed. Address electrodes are provided for each monochromatic pixel column and selectively connected with the pads above them, performing simultaneous selection of lines.

摘要： A plasma display panel and driving method thereof perform addressing at a high speed and a low voltage without deteriorating contrast. Priming electrodes forming priming cells are located outside but adjacent a display area. Glow occurring in the priming cells is intercepted. When priming discharge is induced at a reset step, voltages lower than a discharge start voltage are applied to first (X) and second (Y) electrodes and third (address) electrodes respectively. Despite the voltages being lower than the discharge start voltage, once discharge is induced in the priming cells, discharge starts in adjoining cells. The discharge then spreads successively over all the cells, thus inducing discharge in all the cells. Consequently, wall charge is produced in all the cells.

摘要： A semiconductor delay circuit device comprises a pair of transistors of the same conduction type having source regions that are arranged adjacent to each other and facing each other, and a substrate contact diffusion region whose conduction type is opposite to that of the source regions. The substrate contact diffusion region extends between the source regions. Therefore, the source regions of the transistors do not influence each other.

摘要： Noise pulses having both polarities which are superposed on an input signal having a binary state of H/L levels forming a rectangular waveform, are suppressed or eliminated before transferring the input signal to an output stage. A noise pulse suppressing circuit is provided which comprises a latch circuit, a counter circuit, and a logic circuit including NAND gates and INVERTERs. For the latch circuit and the counter circuit, D-type flip-flops are also utilized. The input signal is inputted to a data input terminal of a flip-flop of the latch circuit and outputted from the data output terminal thereof. The latch circuits are triggered by a pulse signal applied to a clock terminal thereof. The above triggering pulse signal is generated by the counter circuit and the logic circuit, and it has a short pulse waveform responding to the input signal but delayed. No pulse in the output is produced which corresponds to the noise pulses in the input signal.
