摘要： A plasma display panel driving method, in which a reset step, an address step, and a display sustaining step are performed on unit subfields, is provided. In the reset step, the charge states of display cells to be driven are uniformed. In the address step, wall charges with a predetermined voltage are formed on only display cells to be turned on. In the display sustaining step, alternating current pulses are applied to all of the display cells, so that only the display cells having the wall charges perform display discharge. In embodiments, the width of AC pulses and portions of the pulses applied to all of the display cells varies in the display sustaining step.

摘要： A plasma display panel sustain-discharge circuit. First and second signal lines for supplying first and second voltages and at least one inductor coupled between one end of the panel capacitor and a third voltage are formed. Energy is stored in the inductor through a path formed between the third voltage and the first signal line in a state where a voltage of one end of the panel capacitor is substantially fixed to the first voltage. The voltage of one end of the panel capacitor substantially decreases to the second voltage using resonance current generated between the inductor and the panel capacitor and the stored energy. Energy is stored in the inductor through a path formed between the third voltage and the second line in a state where a voltage of one end of the panel capacitor is substantially fixed to the second voltage. The voltage of one end of the panel capacitor substantially increases to the first voltage using the resonance current generated between the inductor and the panel capacitor and the stored energy.

摘要： Disclosed is a reset waveform of a plasma display panel. A rising or falling voltage is applied rapidly enough to cause an intense discharge in a reset interval. The electrodes are then floated to reduce the voltage applied into a discharge space during the discharge to cause a self-quenching of the discharge, thereby precisely controlling wall charges.

摘要： A panel driving method for driving pixels of a panel. The pixels are classified into a plurality of groups and the pixels of one of the plurality of groups are addressed and sustain-discharged before the pixels of another one of the plurality of groups are addressed and sustain discharged. In the panel driving method, a frame period for displaying a single image is divided into a plurality of sub-fields, each of which has a predetermined gradation, and the sub-fields are selectively operated to determine a gradation of visual brightness for each cell. In at least one of the sub-fields, an address period and a sustain period are sequentially performed on the pixels of each of the groups. While an address period is being performed on the pixels of a one of the groups, the pixels of other groups are idle. While a sustain period subsequent to the address period is being performed on the pixels of one of the group, a sustain period is selectively performed on the pixels of each of other groups that have already undergone an address period.

摘要： An average bidirectional flow tube, including a body having two side plates and upper and lower plates, a partition plate installed to be perpendicular to the side plates of the body so that front and rear ends of the tube are separated from each other, and two pairs of pressure impulse lines installed at front and rear positions of the partition plate. The upper and lower plates of the body each have a curvature to be in contact with an inner surface of a pipe in which the average bidirectional flow tube is installed, and each of the pressure impulse lines is installed to communicate with an interior of the pipe. Although a two-phase flow occurs in the pipe or the flow of the fluid flowing in the pipe is changed, an average flow rate of a fluid can be measured. Particularly, it is easy to measure an average flow rate of the fluid when the fluid flows at a low speed. Further, even when sudden pressure reduction occurs in the pipe, an additional cooling device is not required. When a two-phase flow occurs in the pipe, the fluid suffers a phase change due to the sudden pressure reduction of the pipe, or a stratified flow occurs due to the two-phase flow in a horizontal pipe, it is unnecessary to displace the average bidirectional flow tube.
