摘要： A signal transfer circuit in a pre-drive circuit converts the reference potential of a control signal, supplied from a drive control circuit, to the reference potential of an output element. The control signal is then amplified in a signal amplifier circuit and thereafter supplied to the output element. This makes it possible to isolate the reference potential and transfer the control signal to the output element even when the reference potentials of the drive control circuit and the control signal are different from that of the output element. The drive control circuit can also be prevented from being affected by variations in potential of the output element or the like.

摘要： A predrive circuit, a drive circuit and a display device which are capable of driving output elements so as to transmit control signals stably even when reference potentials generated on the output elements side turn to high voltage. A first level shift circuit outputs a flow signal which is an input signal according to a first level shift potential. A second level shift circuit outputs a flow signal which is the flow signal output from the first level shift circuit, according to a second reference potential. A level shift power supply circuit supplies the level shift potential based on a prescribed power supply voltage and the second reference potential to the first level shift circuit and the second level shift circuit.

摘要： An air purifier includes a main body defining an air passage therein to allow sucked air to pass therethrough prior to being discharged, and a first filter installed in the main body to be switched between a closed state and an open state. The first filter removes contaminants from the sucked air in the closed state, and allows the sucked air to pass through the air passage in the open state. The air purifier may include a main body to suck and discharge air, with a bypass passage formed in the main body so that the bypass passage is opened or closed by a door, and a first filter installed in the main body. The sucked air passes through the first filter prior to being discharged when the door is closed, and passes through the bypass passage prior to being discharged when the door is opened.

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 method of driving a plasma display is disclosed, in which the deterioration of the display quality which otherwise might be caused by the light emission due to a reset pulse is prevented thereby to improve the display quality. The voltage of the reset pulse is set taking the voltage due to the accumulated charge into consideration in accordance with a specific display. In this way, the self-erasure discharge is not caused in all the cells but only in the cells involved in display. The display brightness is set also for the self-erasure discharge as a discharge involved in display like the sustaining discharge.

摘要： Method for driving a plasma display panel. At least one first discharge sustaining pulse is applied to a first pair of display electrodes, and at least one second discharge sustaining pulse applied to an adjacent pair of display electrodes.
