    摘要： A method for driving an AC-type Plasma Display Panel (PDP), and more particularly, for improving the brightness and contrast of the panel by reducing the time of scanning while increasing the discharge time of cells. Accordingly, a video signal is designed to change, as needed, the sequential order of two bits, to insert appropriate erasing pulses into vertical electrodes according to the sequential order of the two bits, and to select the erasing time of each cell being connected to horizontal electrodes. Thus, combining any two or a plurality of subfields reduces the time of scanning while increasing the discharging time of the cells.

    摘要： An impulse generation circuit is provided for generating an impulse using a transmission line. Impulse characteristics of the impulse generation circuit are varied with the length of a transmission line rather than the characteristic variation of various devices used therein. The length of the transmission line is adjusted, such that a width of a generated pulse is adjusted. Because an end of the transmission line is short-circuited, the transmission line length can be easily adjusted on a substrate, and a ringing phenomenon due to re-reflection can be removed using termination impedance.

    摘要： A method of and system for driving a plasma display panel (PDP), which is designed to increase the amount of data processed in unit time. The method includes the steps of dividing row electrodes into at least two groups, splitting the field, and applying driving pulses to each split field with a phase difference. Also, the present invention uses a lower bit preceding scanning method where the bits of a digital picture signal are aggregated by bits of a kind from the most significant bit to the least significant bit and divided into a plurality of pairs of upper and lower bits as (lower bit, upper bit), the lower bit in each pair of bits being successively scanned, followed by a scanning of the upper bit in each pair of bits. Thus, the efficiency of the AC PDP is enhanced with the reduction in the time needed to construct the field, and readily driving a field even when the amount of data to be scanned is increased.
